The battery in the lantern might be dead or the fall might have broken it.
Now, we know that the number of electrochemical equivalents electrolysed is proportional to the whole amount of electricity which passed through the circuit, and the product of this by the electromotive force of the battery is the work done by the latter, so that in this case also Joule showed that the heat generated was proportional to the work done.
I bought a battery, but it didn't do any good.
"It had a small size battery pack on the back," Howie offered, "not as large as a car battery."
I just came back from a battery of tests that said nothing's wrong with me.
He bought some battery powered lights to hang on the wagon and Gerald helped him pile hay on the wagon.
To the left from that village, amid the smoke, was something resembling a battery, but it was impossible to see it clearly with the naked eye.
We're building a bigger battery to store the energy we generate from the river, but … Kelli shrugged.
Christ, it tastes like battery acid.
Pierre went to the battery and the adjutant rode on.
On the opposite side the enemy could be seen by the naked eye, and from their battery a milk-white cloud arose.
Incoming currents pass from line through one coil of the relay, the key, and either the battery or battery resistance, according as whether the key is raised or depressed.
All I do is pull the battery and store the old gal together with half my gear and the next summer she's as raring and ready as I am.
And the solar battery farther back.
Deidre dug through her purse as she walked and pulled out her cell, thrilled to see she had battery power.
Normally a switch attached to the key cuts the battery off, and connects the line direct through the receiving relay; this switch is turned to " send " when transmission commences, and is moved back to " receive " when it ceases: this movement is done quite mechanically by the telegraphist, and as it is practically never forgotten, automatic devices (which have often been suggested) to effect the turning are wholly unnecessary.
By this method of transmission the battery is always to the line for the same interval of time, and alternately with opposite poles, so that the effect of electrostatic induction is reduced to a minimum.
We can get a view from there and in our battery it is still bearable, said the adjutant.
When a key is depressed, slightly raising one of the pins, the horizontal arm will pass over it and in doing so will momentarily join the battery to the line.
The singleneedle instrument is a vertical needle galvanoscope worked by a battery and reversing handle, or two " tapper " keys, the motions to right and left of one end of the index corresponding to the dashes and dots of the Morse alphabet.
At the same time the commander of the artillery of the 1st Corps, General Pernetti, with thirty cannon of Campan's division and all the howitzers of Dessaix's and Friant's divisions, will move forward, open fire, and overwhelm with shellfire the enemy's battery, against which will operate:
But the men in the battery seemed not to notice this, and merry voices and jokes were heard on all sides.
From the battery they could be seen running back past it carrying their wounded on their muskets.
Some militiamen who were entering the battery ran back.
The ratio of this to the whole work done by the battery is (C - C')/C, so that the efficiency is increased by diminishing C'.
It is not possible to work double current from one set alone, as in this case, if one key of a group of instruments is up and another is down, the battery would be short-circuited and no current would flow to line.
By the use of a key in the battery circuit as well as an interrupter or current reverser, signals can be given by breaking up the continuous hum in the telephone into long and short periods.
If they attack our center we, having the center battery on this high ground, shall withdraw the left flank under its cover, and retreat to the dip by echelons.
Mounting his horse again Prince Andrew lingered with the battery, looking at the puff from the gun that had sent the ball.
In the center Tushin's forgotten battery, which had managed to set fire to the Schon Grabern village, delayed the French advance.
On the contrary, the energetic action of that battery led the French to suppose that here--in the center--the main Russian forces were concentrated.
The commander of the artillery of the 3rd Corps, General Fouche, will place the howitzers of the 3rd and 8th Corps, sixteen in all, on the flanks of the battery that is to bombard the entrenchment on the left, which will have forty guns in all directed against it.
The guns of that battery were being fired continually one after another with a deafening roar, enveloping the whole neighborhood in powder smoke.
"Now then, you foxes!" said another, laughing at some militiamen who, stooping low, entered the battery to carry away the wounded man.
After this from amid the ranks of infantry to the right of the battery came the sound of a drum and shouts of command, and from the battery one saw how those ranks of infantry moved forward.
On the right of the battery soldiers shouting "Hurrah!" were running not forwards but backwards, it seemed to Pierre.
If we could drive the engine so fast as to reduce C' to zero, the whole of the energy of the battery would be available, no heat being produced in the wires, but the horse-power of the engine would be indefinitely small.
von Jacobi showed that for a given electromotive force in the battery the horse-power is greatest when the current is reduced to one-half of what it would be if the engine were at rest.
4); a current is sent from a battery, E, through one coil of a galvanometer, g, through a high resistance, r, through one of the wires, r, and thence back from office B (at which the wires are looped), through wire 2, through another high resistance, r', through a second coil on the galvanometer, g, and thence to earth.
Total insulation resistance of looped lines = 2 R(D/d - 1); in which R is the total resistance of the looped wires, including the resistance of the two coils of the galvanometer, of the battery, and of the two resistance coils r and r' (inserted for the purpose of causing the leakage on the lines to have a maximum effect on the galvanometer.
It will be observed that the circuit is not in this case actually open; the meaning of the expression " open circuit " is " no battery to line."
It differs from the open circuit in only requiring one battery (although, as in the figure, half of it is often placed at each end), in having the re circuit ceiving instrument between the line and the key, and in having the battery continuously to the line.
The battery is kept to the line by the bar c, which short-circuits the keys.
When only one battery is used the current at the distant end may be considerably affected by the leakage to earth along the line.
If long circuits were worked direct with ordinary instruments, high battery power would be required in order to send sufficient Single current to actuate the apparatus.
In such cases it is usual to employ a local battery to produce the signals, and to close the local battery circuit by means of a relay working.
The local 1_ E I battery B 1 then sends a current through the in FIG.
23, representing the " differential " method, B is the sending battery, B 1 a resistance equal to that of the battery, R a rheostat and C an adjustable condenser.
In this case no current flows from the battery through the line or instruments, the whole action being inductive.
In the raised position a negative battery is connected to the distributor and in the depressed position a positive battery.
battery and to earth alternately, the relative time sender during which it is to battery and to earth depending to a great extent on the operator.
35) were sunk in the water; the pair on one side were connected by a battery B, and the pair on the other by a galvanometer or telegraphic receiver R.
Under these circumstances a small portion of the current from the battery is shunted through the galvanometer circuit, and can be used to make electric signals.
He found, as others have dune, that if a battery, dynamo or induction coil has its terminals connected to the earth at two distant places, a system of electric currents flows between these points through the crust of the earth.
Hence, by inserting a break-and-make key in the circuit of the battery, coil or dynamo, the uniform noise or hum in the telephone can be cut up into periods of long and short noises, which can be made to yield the signals of the Morse alphabet.
"That's our battery," said the staff officer indicating the highest point.
His eyes ran rapidly over the wide space, but he only saw that the hitherto motionless masses of the French now swayed and that there really was a battery to their left.
"And, if your excellency will allow me to express my opinion," he continued, "we owe today's success chiefly to the action of that battery and the heroic endurance of Captain Tushin and his company," and without awaiting a reply, Prince Andrew rose and left the table.
Having forced his way out of the crowd of fugitives, Prince Andrew, trying to keep near Kutuzov, saw on the slope of the hill amid the smoke a Russian battery that was still firing and Frenchmen running toward it.
Higher up stood some Russian infantry, neither moving forward to protect the battery nor backward with the fleeing crowd.
The French had attacked the battery and, seeing Kutuzov, were firing at him.
Rostov riding in front gave the order "Forward!" and the hussars, with clanking sabers and subdued talk, their horses' hoofs splashing in the mud, defiled in fours and moved along the broad road planted with birch trees on each side, following the infantry and a battery that had gone on in front.
The squadron overtook and passed the infantry and the battery--which had also quickened their pace--rode down a hill, and passing through an empty and deserted village again ascended.
Having reached the knoll, Pierre sat down at one end of a trench surrounding the battery and gazed at what was going on around him with an unconsciously happy smile.
Beside himself with terror Pierre jumped up and ran back to the battery, as to the only refuge from the horrors that surrounded him.
Later, while attempting to utilize the gas for the production of electricity by means of a Grove gas battery, he noticed that the carbon monoxide contained in it combined with nickel.
- Universal Battery Working.
The result is that the armature of the relay is attracted, and currents are sent through the sounder from the local battery, producing the signals from the distant station.
In contrast with the dread felt by the infantrymen placed in support, here in the battery where a small number of men busy at their work were separated from the rest by a trench, everyone experienced a common and as it were family feeling of animation.
My wife is like a battery.
The electromotive force of each cell is i 07 volts and the resistance 3 ohms. The Fuller bichromate battery consists of an outer jar containing a solution of bichromate of potash and sulphuric acid, in which a plate of hard carbon is immersed; in the jar there is also a porous pot containing dilute sulphuric acid and a small quantity (2 oz.) of mercury, in which stands a stout zinc rod.
Elec. Eng., 27, p. 938.) It may be explained as follows: - Suppose a battery on shore to have one pole earthed and the other connected to an insulated submarine cable, the distant end of which was also earthed; if now a galvanometer is inserted anywhere in the cable, a current will be found flowing through the cable and returning by various paths through the sea.
If a battery on the mainland is connected through a key with the shore end of the main cable, and a speaking galvanometer is in circuit with the short cable crossing the Fastnet rock, then closing or opening the battery connexion will create a deflection of the galvanometer.
He proposed to employ two large flat coils of wire laid horizontally, on the ground, that on the mainland having in circuit a battery, interrupter and key, and that on the island a telephone.
At the sending station one battery was to have its positive pole connected to the earth and its negative pole to an insulated condenser.
In circuit with this battery was placed the secondary circuit of an induction coil, the primary circuit of which contained a telephone transmitter or microphone interrupter.
At the receiving station a telephone receiver was placed in series with another insulated battery, the negative terminal of which was to be in connexion with the earth.
He discovered a fact subsequently rediscovered by others, that a tube of metallic filings, loosely packed, was sensitive to electric sparks made in its vicinity, its electrical resistance being reduced, and he was able to detect effects on such a tube connected to a battery and telephone at a distance of 500 yds.'
The relay was employed to actuate through a local battery B2 an ordinary Morse printing telegraphic instrument M.
Marconi 2 imparted practical utility to this idea by tuning the two circuits together, and the arrangement now employed is as follows: - A suitable condenser C, or battery of Leyden jars, has one coating connected to one spark ball and the other through a coil of one turn with the other spark ball of a discharger S.
In this case a closed condenser circuit is formed with a battery of Leyden jars, an inductance coil and a spark gap, and oscillations are excited in it by discharges created across the spark gap by an induction coil or transformer.
The main capacity in this last circuit consists of a battery of Leyden See J.
The relay itself served to actuate a Morse printing telegraph by means of a local battery.
Ann., 1890, 40, p. 56) employed an arrangement as follows: Four fine platinum or iron wires were joined in lozenge shape, and two sets of these R and S were connected up with two resistances P and Q to form a bridge with a galvanometer G and battery B.
Fleming discovered that if the filament is made incandescent by the current from an insulated battery there is a unilateral conductivity of the rarefied gas between the hot filament and the metal plate, such that if the negative terminal of the filament is connected outside the lamp through a coil in which electric oscillations are created with the platinum plate, only one half of the oscillations are permitted to pass, viz., those which carry negative electricity from the hot filament to the cooled plate through the vacuous space.
A battery with a sufficient number of cells is connected to these two electrodes so as to pass a current through the mercury vapour, negative electricity proceeding from the mercury cathode to the iron anode.
- A, antenna; P S, jigger or oscillation transformer; C, condenser; 0, Fleming oscillation valve; B, working battery; T, telephone; R, rheostat; E, earth-plate.
His transmitter consists of a nearly closed oscillating circuit comprising a condenser or battery of Leyden jars, a spark gap, and the primary coil of an oscillation transformer consisting of one turn of thick wire wound on a wooden frame.
The instrument was joined in circuit with a battery and another similar instrument placed at a distance; and a continuous current was made to flow through the circuit, keeping the electromagnets energized.
The current from the battery used passed from the diaphragm through the granulated carbon to the metallic back of the box.
The current from the battery passes from one of the carbon disks to the other through the particles of granulated carbon which fill the space between them.
The telephone was switched out of circuit when not in use and the bell put in its place, a key being used for throwing the battery into circuit to make the signal.
7, the microphone, a battery and the primary of an induction coil in a local circuit, and putting the line in circuit with the secondary of the induction coil, which acted as the transmitter.
The requisite energy is derived from the battery.
Though many types of manually operated switchboards have been brought into use, differing from each other in respect of circuit and working arrangements, yet each of them may be placed in one or other of three main classes according as the system of working is magneto, call-wire, or common battery.
There are still many magneto exchanges in existence, but when new exchanges are erected only the very smallest are equipped for magneto working, that system having succumbed to the common battery one in the case of all equipments of moderate and large dimensions.
One of the greatest advances made in the development of the art of telephony was the introduction of the " common battery relay system."
- Hayes Common Battery System.
9) is characterized by the use of impedance coils between the battery and the line wires.
- Stone Common Battery System.
- Dean Common Battery System.
- Subscriber's Circuit, Common Battery System.
The impedance coils shown connected between the battery and the lines and between the latter and the transmitters are joined up non-inductively as regards the transmitter circuits, but inductively as regards the secondary circuits.
The conditions permit of the circulation of the alternating currents of low periodicity, which are used for operating the bells, but in respect of the battery the circuit is open until the subscriber lifts the receiver, when the hook switch, thus released, joins the transmitter with one winding of an induction coil in series across the circuit.
Calls are registered by pressing a key, which connects a battery through a position meter of very low resistance to the socket of the line jack, thereby furnishing the necessary energy to the meter.
But he is immortal as the man against whom Kant directed his tremendous battery 1 Human attributes magnified, or their weak points thought away.
On one side; another battery of Kant's was aimed against Hume.
In addition to tentacles, there may be marginal cirri (Laodice) with a solid endodermal axis, spirally coiled, very contractile, and bearing a terminal battery of nematocysts.
In Monument Square, the site of a battery in 1775 is a soldiers' and sailors' monument (1889), a tall granite pedestal surmounted by a bronze female figure, by Franklin Simmons; at the corner of State Street is a statue of Henry W.

the plate attached to the so-called positive terminal of the battery or other source of current, dissolves away, the copper going into solution as copper sulphate.
Alessandro Volta of Pavia discovered the electric battery in the year 1800, and thus placed the means of maintaining a steady electric current in the hands of investigators, who, before that date, had been restricted to the study of the isolated electric charges given by frictional electric machines.
They also noticed that a similar kind of chemical action went on in the battery itself.
In 1807 he decomposed potash and soda, previously considered to be elements, by passing the current from a powerful battery through the moistened solids, and thus isolated the metals potassium and sodium.
Now let us disconnect the platinum plates from the battery and join them directly with the galvanometer.
above sea-level; (c) another group of batteries on the narrow ground between the sea and the lake to the east of the town; the highest of these is the Jebel Tuila battery 265 ft.
The inner coil is supplied, through the intervening apparatus, with current from the battery of secondary cells B,; this produces the desired magnetic field inside the tube.
The magnetizing current, which is derived from the storage battery B, is regulated by the adjustable resistance R and measured by the galvanometer G.
By means of the three-way switch C the battery current may be sent either into the primary of E, for the purpose of calibrating the galvanometer, or into the magnetizing coil of the ring under test.
and on the Argyll battery stands a huge piece of ancient artillery,.
Electric locomotives usually work on the trolley system, though a few storage battery locomotives have been successfully employed.
Any Turkish battery that was chosen for target generally ceased firing before long; and the assailants were disposed to assume that the work was definitely put out of action, whereas all that had happened in reality was that the hostile gunners had been driven from their guns.
In diffusion plants the milk of lime is added, in proper proportion, in the cells of the diffusion battery, and the chips or slices themselves act as a mechanical filter for the juice; while in the Sandwich Islands coral-sand filters have been employed for some years, in addition to the chips, to free the juice from impurities held in mechanical suspension.
A cell when filled with fresh slices becomes the head of the battery, and where skilled scientific control can be relied upon to regulate the process, the best and most economical way of heating the slices, previous to admitting the hot liquor from the next cell, is by direct steam; but as the slightest inattention or carelessness in the admission of direct steam might have the effect of inverting sugar and thereby causing the loss of some portion of saccharine in the slices, water heaters are generally used, through which water is passed and heated up previous to admission to the freshly-filled cell.
When the new cell comes into operation and becomes the head of the battery, the first or tail cell is thrown out, and number two becomes the tail cell, and so the rounds are repeated; one cell is always being emptied and one filled or charged with slices and heated up, the latter becoming the head of the battery as soon as it is ready.
In a refinery in Nova Scotia a system has been introduced by which a travelling crane above the bag filters lifts up any head bodily with all its bags attached, and runs it to the mud and washing tanks at the end of the battery, while another similar crane drops another head, fitted with fresh bags, into the place of the one just removed.
1400), earl and prince of Orkney and 1st earl of Caithness, its last vestiges having been demolished in 1865 to provide better access to the harbour; and the earthwork to the east of the town thrown up by the Cromwellians has been converted into a battery of the Orkney Artillery Volunteers.
For the theory and elemental laws of electro-deposition see Electrolysis; and for the construction and use of electric generators see Dynamo and Battery: Electric. The importance of the subject may be gauged by the fact that all the aluminium, magnesium, sodium, potassium, calcium carbide, carborundum and artificial graphite, now placed on the market, is made by electrical processes, and that the use of such processes for the refining of copper and silver, and in the manufacture of phosphorus, potassium chlorate and bleach, already pressing very heavily on the older non-electrical systems, is every year extending.
One of the best methods for doing this is to charge the Ab l condenser by the known voltage of a battery, and then d e t erdischarge it through a galvanometer and repeat this minations.
The metal slips are so placed that, as the disk revolves, the middle brush, connected to one terminal of the condenser C, is alternately put in conductive connexion with first one and then the other outside brush, which are joined respectively to the battery B and galvanometer G terminals.
These arms. are then altered until on raising or depressing the battery key there is no sudden deflection either way of the galvano meter.
It depends on the principle that if two condensers of capacity C I and C2 are respectively charged to potentials V I and V2, and then joined in parallel with terminals of opposite charge together, the resulting potential difference of the two condensers will be V, such that V = (C,V 2 -CiV2) /(C1+C2) (16); and hence if V is zero we have C I: C2 = V2 The method is carried out by charging the two condensers to be compared at the two sections of a high resistance joining the ends of a battery which is divided into two parts by a movable contact.'
A simple method for condenser comparison is to charge the two condensers to the same voltage by a battery and then discharge them successively through a ballistic galvanometer and observe the respective " throws " or deflections of the coil or needle.
South, east and west of the city are the gold mines, indicated by tall chimneys, battery houses and the compounds of the labourers.
lumps in a rock-breaker, is fed in through an aperture at the back of the " battery box," a constant supply of water is admitted from above, and mercury in a finely divided state is added at frequent intervals.
Similar plates are often used to catch any particles of gold that may be thrown back, while the main operation is so conducted that the bulk of the gold may be reduced to the state of amalgam by bringing the two metals into intimate contact under the stamp head, and remain in the battery.
So sudden was the collision that the Prussian advanced guard battery had to fire case to clear its own front.
Marshal Bazaine had meanwhile arrived on the scene, and ordering forward fresh troops to relieve (not to reinforce) those already engaged, he rode forward with a horse artillery battery to watch the operations.

Delivered in three echelons, these final attacks were repulsed, the first echelon by Colin Halkett's British Brigade, a Dutch-Belgian battery, and a brigade of Chasse's Dutch-Belgian division; the second and third echelons by the Guards, the 52nd, and the Royal Artillery.
In this case one terminal of the battery is connected to the earth, and the other terminal is connected through the galvanometer with the copper wire, the insulation of which it is desired to test.
battery is applied to the shunted galvanometer, then the current C passing through the galvanometer will be given by the expression SV C - R' (R +S) +RS' where V is the electromotive force of the battery.
It is possible so to arrange the value of the shunt and of the high resistance R' that the same or nearly the same deflection of the galvanometer is obtained as when it is used in series with the battery and the insulation-resistance.
In these circumstances the current passing through the galvanometer is known, provided that the voltage of the battery is determined by means of a potentiometer.
Hence the resistance of the insulator can be ascertained, since it is expressed in ohms by the ratio of the voltage of the battery in volts to the current through the C C galvanometer in amperes.
which is connected to one terminal of the insulated battery B, the other terminal being connected to the metallic conductor CC of the wire under test, through a galvanometer G.
To prevent leakage over the surface of the insulating covering of the wire which projects above the surface of the water, it is necessary to employ a " guard wire P, which consists of a piece of fine copper wire, twisted round the extremity of the insulated wire and connected to the battery.

The seamen, instead of dropping down on the battery, had to go back to it 400 yd.
The "fortified zone," instead of being between the "Vindictive" and the shore, was now between the "Vindictive" and the battery on the mole, increasing the difficulty of an assault.
In 1808 Sir Humphry Davy, fresh from the electrolytic isolation of potassium and sodium, attempted to decompose alumina by heating it with potash in a platinum crucible and submitting the mixture to a current of electricity; in 1809, with a more powerful battery, he raised iron wire to a red heat in contact with alumina, and obtained distinct evidence of the production of an iron-aluminium alloy.
Both schemes appeared practically impossible; potassium cost about L 1 7 per lb, gave a very small yield and was dangerous to manipulate, while on the other hand, the only source of electric current then available was the primary battery, and zinc as a store of industrial energy was utterly out of the question.
The main fortification of Copenhagen was the powerful Trekroner (Three Crown) battery at the northern end of the sea-front.

Not the least extraordinary feature of the battle that followed is the part played by a sangar of stones at the head of Quarry Ravine and a small battery, called the Sandbag Battery, made as a temporary emplacement for two heavy guns a few days before.
Possession of the Sandbag Battery was far more fiercely contested.
The line of defence adjacent to the battery looked downhill for about 300 yds., giving a clear field of fire for the new Enfield rifle the English carried; but a sharp break in the slope beyond that range gave the assailants plenty of "dead ground" on which to form up. For a time, therefore, the battle was a series of attacks, delivered with great fierceness by the main body of Pavlov's corps, the repulse of each being followed by the disappearance of the assailants.
Most of the division indeed had to be used to patch up the weaker parts of the line, but Cathcart himself with about 400 men worked his way along the lower and steeper part of the eastern slope so as to take the assailants of the battery in flank.
Thenard, who had no battery at their disposal, to search for a chemical method of obtaining those metals, and by the action of red-hot iron on fused potash - a method of which Davy admitted the advantages - they succeeded in 1808 in preparing potassium, going on to make a full study of its properties and to use it, as Davy also did, for the reduction of boron from boracic acid in 1809.
When the two metal surfaces are connected for a short time with the terminals of some source of electromotive force, such as an electric machine, an induction coil or a voltaic battery, electric energy is stored up in the condenser in the form of electric strain in the glass, and can be recovered again in the form of an electric discharge.
This arrangement is commonly called a battery of Leyden jars.

Repsolds also provide two insulated sliding contact rings instead of the single ring g, so that the electric current for illuminating the lamps does not pass through the instrument itself but may come to the micrometer from the storage battery through two insulated leads.
Extending his investigations to the currents produced by batteries, he found that the total voltaic heat generated in any circuit was proportional to the number of electrochemical equivalents electrolysed in each cell multiplied by the electromotive force of the battery.
If a battery of electromotive force E maintain a current C in a conductor, and no other electromotive force exist in the circuit, the whole of the work done will be converted into heat, and the amount of work done per second will be EC. If R denote the resistance of the whole circuit, E = CR, and the heat generated per second is C 2 R.
Then the work done by the battery per second will be EC' or CC'R, while the heat generated per second will be C' 2 R, so that we have the difference (C - C')C'R for the energy consumed in driving the engine.
The reason why the whole of the energy of the current is not available is that heat must always be generated in a wire in which a finite current is flowing, so that, in the case of a battery in which the whole of the energy of chemical affinity is employed in producing a current, the availability of the energy is limited only on account of the resistance of the conductors, and may be increased by diminishing this resistance.
16, in which L 1 represents the line, G a galvanometer, used simply to show that the currents are going to line circuit, when the message is being transmitted, K the trans- - mitting key, B the battery, I the receiving instrument, and E the earth-plate.
A signal is sent by depressing the key K, and so changing the contact from a to b, and thus putting the battery r -- to line.
This system is more expen sive than the open-circuit system, ®' as the battery is always at work; but it offers some advantages on circuits where there are a number 'a' N% b '.a of intermediate stations, as the Ã‚° Ã‚° circuit is under a constant electro motive force and has the same resistance no matter which station is sending or receiving.
The key K (shown in general plan), when worked, sends reversed currents from the battery B.
In cases where " universal battery " working, i.e.
The stop a of the key K is connected through a switch S with one pole of the battery B, and the stop b in the usual way with the other pole.
K 1 and K2 are two transmitting keys; the former reverses the direction of the line current, the latter increases the strength irrespective of direction, by joining on another battery when the key is depressed.
28, be in the ribbon, the rod M will first be allowed to pass through the paper, and the corresponding movement of crank A' will, through the agency of collet K, throw over lever L, and the battery zinc will be put to the line; at the next half stroke of the beam, S will pass through, and crank A by its movement will, through the agency of collet K', throw over lever L in the reverse direction, so that the battery copper will be put to the line.
The apparatus consists of a sending battery B, a reversing transmitting key K, a slide of small resistance 5, three condensers C1, C2, C3, an artificial cable AC, the receiving instruments I and G, and one or more resistances R for adjusting the leakage current.
In actual practice the receiving instrument is so sensitive that the difference of potential between the two coatings of the condenser C3 produced by the incoming signal is only a very small fraction of the potential of the battery B.
By the automatic curb sender the cable is put to one or the other pole of the battery and then to the reverse pole for definite proportionate times during u b c 0 'c' C p t e a n i m e r rn e ll i a.
36), has in circuit a battery B and an in terrupter I, and at some distance and parallel to this primary circuit is placed a secondary circuit S, having a telephone T included in it, the interruptions or reversals of the current in the primary circuit will give rise to a varying magnetic field round that circuit which will induce secondary currents in the other circuit and affect the telephone receiver.
A very ingenious call-bell arrangement was devised, capable of responding only to regularly reversed battery currents, but not 1 See Fahie, History of Wireless Telegraphy, p. 170; also 5th Report (1897) of the Royal Commission on Electrical Communication with Lightships and Lighthouses.
The current circuit went through S, W, C, K, A, and the primary circuit of the induction coil I to the battery B, and thence to S again.
