He bought some battery powered lights to hang on the wagon and Gerald helped him pile hay on the wagon.
We're building a bigger battery to store the energy we generate from the river, but … Kelli shrugged.
Pierre went to the battery and the adjutant rode on.
The absence of fangs and the battery acid blood probably would have saved her life.
On the opposite side the enemy could be seen by the naked eye, and from their battery a milk-white cloud arose.
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 can get a view from there and in our battery it is still bearable, said the adjutant.
The entrance under the facility was hastily dug but the tunnel running beneath the facility had thick metal walls and concrete floors and was lit by battery-operated lanterns.
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'.
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.
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.
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 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.
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 ° ° circuit is under a constant electro motive force and has the same resistance no matter which station is sending or receiving.
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.
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.
In this case no current flows from the battery through the line or instruments, the whole action being inductive.
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.
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.
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.
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.
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:
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.
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.
But the men in the battery seemed not to notice this, and merry voices and jokes were heard on all sides.
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.
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.
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.
Number of stations, the sending battery is sometimes divided among them in order to give greater uniformity of current along the line.
When only one battery is used the current at the distant end may be considerably affected by the leakage to earth along the line.
