It extended the meaning of the term " railroad " to include switches, spurs and terminal facilities, and the term " transportation " to include private cars, and all collateral services, such as refrigeration, elevation and storage.
Each subscriber's circuit on this system terminates upon the incoming portion of a selector switch, called a first selector, and is multipled upon the outgoing portions of a number of similar switches called connector switches.
Only calls originated by a subscriber pass through the selector switch (first selector) provided for his sole use; the calls incoming to him pass through one or other of the various connector switches upon which his circuit is multipled.
Each connexion involves the use of three switches, viz., a first selector, a connector switch, and a second selector which is brought into operation between the other two.
To enable trains to be transferred from one pair of rails to another pair, as from the main line to a siding, " points " or " switches " are provided.
The effective number of turns in the coil surrounding the test rod can be varied by means of three dial switches (for hundreds, tens and units), which also introduce compensating resistances as the number of effective turns in the coil is reduced, thus keeping the total resistance of the circuit constant.
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.
Switches for turnouts and branches, &c., are similar to but simpler than those for railways.
Of the Coieul river; next the Frêsnes-Rouvroy line and the Vis en Artois switches and finally the Drocourt-Queant line.
There were three metal objects with dials and switches; machines I'll call them, from which the wires ran.
After examining the various dials and switches on Quinn's machines, I had a fairly clear idea of each; I could turn it on and increase and decrease the settings.
He jumped to his feet flipping light switches and stumbling through both rooms, barely seeing still-sleeping Cynthia through eyes pinched nearly closed against the intrusive brightness.
(b) In lieu of oil-lamps, small, conveniently placed incandescent electric 6-volt lamps are employed; and these are fitted with suitable switches and variable resistances.
Provinces when, at the Gurui serpent-festival, women make vicarious offerings by throwing to Nag Deota, the river demon, dolls which the village lads beat with long switches (Crooke ii.
