The current then passes through the coils of an electromagnet, which releases the printing mechanism.

Thus the most efficient vacuum pans of the present day are those which have their coils so arranged that no portion of them exceeds 50 or 60 ft.

Attempts have been made to improve submarine cables in this respect, and in 1906 a short cable " loaded " with Pupin coils was laid across Lake Constance.

Branches are taken off the flow pipe, and after circulating through coils or radiators are connected with the return pipe.

A cord circuit, similar in many respects, including the method .y.^9 Jr '' of operation, but equipped with condensers and impedance coils, in place of the repeating coil, is shown in fig.

If a current is passed through the fixed coil and movable coil in series with one another, the movable coil tends to displace itself so as to bring the axes of the coils, which are normally at right angles, more into the same direction.

This tendency is resisted by the weight of a mass of metal, which can be caused to slide along a tray attached to the movable coils.

Dorsal valve, showing calcareous spiral coils.

If each portion of the bar has an independent magnetizing coil wound tightly upon it, we have further to take into account the force due to, the mutual action of the two magnetizing coils, which assists.

To reduce the effect of these error fields, a set of error field correction coils was installed on the MAST tokamak.

The two coils are connected in series, the same current passing through both.

Suppose the switches to be adjusted so that the effective number of turns in the variable coil is loo; the magnetizing forces in the two coils will then be equal, and if the test rod is of the same quality as the standard, the flow of induction will be confined entirely to the iron circuit, the two yokes will be at the same magnetic potential, and the compass needle will not be affected.

The difference of the ballastic throws taken with the two coils measured the intensity of the field in the space around the iron, and it also enabled a correction to be made for the nonferrous space between the iron neck and the centre of the thickness of'the inner coil.

Touches of colour may be added to vessels in course of manufacture by means of seals of molten glass, applied like sealing-wax; or by causing vessels to wrap themselves round with threads or coils of coloured glass.

By the application of a pointed iron hook, while the glass is still ductile, the parallel coils can be distorted into bends, loops or zigzags.

The latter are circular or rectangular vessels, holding from 500 to 1500 gallons each, according to the capacity of the factory, and fitted with steam coils at the bottom and skimming troughs at the top. In them the syrup is quickly brought up to the boil and skimmed for about five minutes, when it is run off to the service tanks of the vacuum pans.

The filter is either a separate piece of plant, or, as in the Quiggins form, it may be placed below the coils in the same outer vessel.

The main rope, which draws out the loaded tubs, coils upon one drum, and passes near the floor over guide sheaves placed about 20 ft.

An ohmmeter in one form consists of two pairs of coils, one pair called the series coil and the other called the shunt coil.

The two coils, the shunt and the series coil, then produce two magnetic fields, with their lines of force at right angles to one another.

In the other gap are pivoted two coils wound on an iron core and connected at nearly a right angle to each other.

One of these coils is in series with the armature circuit and with the insulation or high resistance to be measured.

When the armature is rotated, these two coils endeavour to place themselves in certain directions in the field so as to be perforated by the greatest magnetic flux.

Another illustration is afforded by a long spiral of wire with coils, say 2 in.

The current to be measured is passed through the coils of the electromagnet, then enters the mercury disk at the centre, flows through it radially in all directions, and emerges at the periphery.

Below this pendulum let there be placed another coil through which passes the current to be measured; then when currents pass through these coils the pendulum of the second clock will be either accelerated or retarded relatively to the other clock, since the action of gravity is supplemented by that of an electric attraction or repulsion between the coils.

Under the disk are two other coils which areTplaced in series with the supply.

A common source of trouble is the short circuiting of the shunt coils owing to the shellaced cotton covering of the wire becoming moist.

The resistance of the meter coils causes a fall in voltage down the series coil which reduces the supply pressure to the consumer.

One terminal of the galvanometer can then be shifted to the junction 6 7 g between any pair of consecutive coils and the slider shifted to any point on the potentiometer wire.

In some cases the potentiometer wire is wholly replaced by a series of coils divided into small subdivisions.

The fixed coil is called the current coil, and the movable coil is called the potential coil, and each of these coils has its ends brought to separate terminals on the base of the instrument.

When the currents flow through the two coils, forces are brought into action compelling the coils to set their axes in the same direction, and these forces can be opposed by another torque due to the control of a spiral spring regulated by moving a torsion head on the instrument.

The torque required to hold the coils in their normal position is proportional to the mean value of the product of the currents flowing through two coils respectively, or to the mean value of the product of the current in the power-absorbing circuit and the potential difference at its ends, that is, to the power taken up by the circuit.

Large Wimshurst multiple plate influence machines are often used instead of induction coils for exciting Rntgen ray tubes in medical work.

It is in the metal in these channels and in that part of the main mass of metal which immediately adjoins the coils that the current is induced by means of the coils and cores, as in the Kjellin furnace.

It is cast hollow, all in one piece, and has the names of the allied states engraved on the lower part of the coils.

A Babylonian cylinder represents two figures (divine?) on either side of a fruit-tree, and behind one of them a serpent coils upwards.

The shrine is famous for its cures, and when the saint has his serpent-festival on the first Thursday in May, Serpari or serpent-men carry coils of live reptiles in procession before his image, which in turn is hung with serpents of all sizes.

The scale values of the records given by the horizontal and vertical force magnetographs are determined by deflecting the respective needles, either by means of a magnet placed at a known distance or by passing an electric current through circular coils of large diameter surrounding the instruments.

Notable, too, is the road in Clear Creek Canyon - where the railway track coils six times upon itself above Georgetown at an altitude of .10,000 ft.

Joseph Henry, in the United States, first suggested the construction of what were then called intensity electromagnets, by winding upon a horseshoe-shaped piece of soft iron many superimposed windings of copper wire, insulated by covering it with silk or cotton, and then sending through the coils the current from a voltaic battery.

On that date he had provided himself with an iron ring, over which he had wound two coils of insulated copper wire.

One of these coils was connected with the voltaic battery and the other with the galvanometer.

The long awn, which is bent and closely twisted below the bend, acts as a driving organ; it isvery hygroscopic, the coils untwisting when damp and twisting up when dry.

In the practical instrument the three arms of the bridge P, Q, and S are generally composed of coils of wire contained in a box, whilst R is the resistance the value of which is to be determined.

In one form of Wheatstone's Bridge, known as the series pattern plug-resistance bridge, or Post Office pattern, the two ratio arms, P and Q, each consist of a series of coils of wire, viz.

When the blocks are interconnected by the plugs all the coils are short-circuited; but if the plug or plugs are taken out, then a current flowing from one"end of the series to the other is compelled to pass through the corresponding coils.
