His bright features turned pink beneath his wire-rimmed glasses and straw-colored hair.
It should be mentioned that an essential feature of the travelling wire micrometer is that the eyepiece as well as the wire shall be moved by the micrometer-screw.
Thus, if the star's image is kept in bisection by the wire, both star and wire will appear at rest in the field of view.
Connexion is made into the office (or to the underground system, as is often the case) from the aerial wire by means of a copper conductor, insulated with gutta-percha, which passes through a " leading in " cup, whereby leakage is prevented between the wire and the pole.
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.
The coated wire is treated in the same way as the copper strand - the die D, or another of the same size, being placed at the back of the cylinder and a larger one substituted at the front.
Some of the containers had a thin wire running around but most were standing alone.
It's so much more effective than rope, or wire, or chains.
For a wire exposed under the conditions observed by Elster and Geitel the emanation seems to be almost entirely derived from radium.
His determinations of pitch by a weighted wire are not trustworthy; Ellis thinks they are not safe within four or five vibrations per second, but gives a mean pitch for this organ, when altered, of a' 395.2.
The length of telegraph lines in use is 46,300 m., and the length of wire nearly three times that distance.
In 1826 he described the prismatically-coloured films of metal, known as Nobili's' rings, deposited electrolytically from solutions of lead and other salts when the anode is a polished iron plate and the cathode is a fine wire placed vertically above it.
It is, however, more commonly and familiarly called " the wire " or " the line."
In the aerial or overground system of land telegraphs the use of copper wire has become very general.
The advantage of the high conducting power which copper possesses Over- is of especial value in moist climates (like that of the United Kingdom), since the effect of leakage over the surface of the damp insulators is much less noticeable when the conducting power of the wire is high than when it is low, especially when the line is a long one.
The sizes of copper wire employed have weights of too, 150, 200 and 400 lb per statute mile, and have electrical resistances (at 60° F.) of 8.782, 5.8 55, 4.39 1 and 2.195 standard ohms respectively.
Copper wire weighing 600 and 800 lb per mile has also been used to some extent.
In.; the test strain required for the iron wire is about 222 tons.
It is essential that the paper covering be loose, so as to ensure that each wire is enclosed in a coating not of paper only, but also of air; the wires in fact are really insulated from each other by the dry air, the loose paper acting merely as a separator to prevent them from coming into contact.
Mastication, and by filtering through wire-gauze filters, is kept warm by a steam-jacket.
As the wire is pulled through, a coating of gutta-percha, the thickness of which is regulated by the die D, is pressed out of the cylinder by applying the requisite pressure
However, the Wizard went once more to his satchel--which seemed to contain a surprising variety of odds and ends--and brought out a spool of strong wire, by means of which they managed to fasten four of the wings to Jim's harness, two near his head and two near his tail.
She shooed the goat back into the pasture and grabbed a pair of linesman pliers and some bailing wire from the barn.
As Josh climbed into his truck, Alex raised the hood and jerked a wire loose.
The iron wire used for wire-netting, telegraphic purposes, &c., is commonly galvanized, as also are bolts, nuts, chains and other fittings on ships.
The subsidiary industries, such as the manufacture of machinery and wire fabric, are of considerable importance.
The radioactivity is denoted by A, and A = signifies that the potential of the dissipation apparatus fell I volt in an hour per metre of wire introduced.
3 The surrounding silver was then dissolved by nitric acid, and a platinum wire of extreme fineness remained.
A wire st is stretched across the centre of the field, perpendicular to the parallel wires.
Each movable web must pass the other without coming in contact with it or the fixed wire, and without rubbing on any part of the brasswork.
To measure distances with the Fraunhofer micrometer, the position-circle is clamped at the true position-angle of the star, and the telescope is moved by its slow motions so that the component A of the star is bisected by the fixed wire; the other component B is then bisected by the web, which is moved by the graduated head S.
It is seen as a clump of wire-like leaves, a few feet in diameter, surrounding a stem, hardly thicker than a walking-stick, rising to a height of Jo or 12 ft.
An important advance on this was proposed in 1797 by Lomond,' who used only one line of wire and an alphabet of motions.
For protection from lightning each pole has an " earth wire " running from the top, down to the base.
The speed of the ship can be roughly estimated from the speed of the engines; it is more accurately obtained by one or other of the various forms of log, or it may be measured by paying out continuously a steel wire over a measuring wheel.
C, where the traffic is small it is usual to make one wire serve several stations.
18, where L is the line wire, joined through the 7 t?
The coils of the electromagnets are differentially wound with silk-covered wire, 4 mils (= 004 inch) in diameter, to a total resistance of 400 ohms. This differential winding enables the instrument to be used for " duplex " working, but the connexions of the wires to the terminal screws are such that the relay can be used for ordinary single working.
Can't you just wire Julie a ticket and make arrangements for her to get to the airport?
To the piston P. The newly coated wire is passed through a long trough T, containing cold water, until it is sufficiently cold to allow it to be safely wound on a bobbin B' This operation completed, the wire is wound from the bobbin B' on to another, and at the same time carefully examined for air-holes or other flaws, all of which are eliminated.
This cone is driven by gearing from the wire drum, so that it rotates at the speed of the outgoing wire, the direction of rotation being such as to cause the nut to travel towards the smaller end of the cone.
On one of them I noticed that the strings were of wire, and having had some experience in bead work, I said I thought they would break.
