Title: An Improved Relay for Electric Circuits.
Inventor: CHRISTIAN DAVID ADAM
IPC: H01H47/14
Filed: 1919-05-23
Abstract: 136,103. Christian, D. A. May 23, 1919. Addition to 131,413. Automatic exchange systems.-Relates to a modification of the test relay described in the parent Specification, in which the relay is provided with differential windings, the middle point of which is connected to the test wiper. According to the present invention, the relay contacts are operated simultaneously or in any required sequence, and an equivalent resistance is substituted for that winding of the relay which is disconnected when the relay is energized. The invention is shown applied to a preliminary selector and a connector. Preliminary selector. The junction 3 of the opposing equal windings 1, 2 of the cut-off relay T is connected to the test wiper. If the tested line is free, its test terminal is connected to battery over a resistance w equal to that of the winding 1 or 2, so that the current in winding 2 is decreased while that in winding 1 is increased. The relay is therefore energized and locks up over winding 1 and contacts t<1>, d, cutting off relay R, which opens the circuit of winding 2. As the resistance w is equal to that of winding 1, the test lead c is at the same potential as the point 3 of any other relay T testing the line. Connector. When the wipers of the connector have been brought to the wanted line, as described in Specification 26905/13, relays C, L are energized and relay V de-energized. Current thus flows through the windings 1, 2 of the test relay P in series, the junction 3<1> being connected to the test wiper. If the selected line is free, current flows from the joint 3' over the test lead c, winding 1 of the cut-off relay T to earth, thereby strengthening the current through winding 1 of relay P and weakening that through winding 2. The relay P therefore energizes, locking up over contacts p<1> and disconnecting winding 2 at contact p<4>. Manual calls. If an operator inserts a plug in jack MJ, relay T is energized over winding 1, and the test lead c is given a busy potential owing to the resistance w<1> being equal to the resistance of the winding 1 or 2 of relay T.

Title: Improvements in or relating to electrical rectifying plant
IPC: H02M7/04
Filed: 1932-05-09
Abstract: 392,735. Rectifier systems; electromagnetic switches. ALLGEMEINE ELEKTRICIT€TS-GES., 2, Friedrich Karl- Ufer, Berlin. May 9, 1932, No. 13363. Convention date, May 8, 1931. Addition to 383,639. [Class 38 (ii).] In a mercury-arc rectifier system comprising a number of rectifiers operating in parallel in which provision is made for extinguishing a rectifier on reduction in load by interrupting its exciter anode circuit and then momentarily interrupting the load circuit as described in the parent Specification, the interruption of the load circuit is limited to a time interval which is so short, e.g. 1/100 of a second, that it is not experienced as an interruption by lamps in the load circuit or by the parallel operating rectifiers. Where gridcontrolled rectifiers are employed, the interruption may be effected by applying a negative potential to the grids. Alternatively, a quickacting circuit in the load circuit may be adapted for the purpose of the invention. The Figure shows such a circuit-breaker in the common D.C. lead 1 from the rectifiers, 2 being the moving contact normally held in by a spring 8 but adapted to be thrown out on overload by current in coil 3. The contact 2 would normally be latched out by latch 5 maintained in latching position in opposition to a spring by current in a coil 7. For effecting momentary interruption of the load circuit for the purpose of the invention the switch is additionally provided with a coil 10 which, when energized, is sufficient, in conjunction with normal load current in coil 3, to throw out the contact 2. The coil 7 is first de-energized to cause the latch to be withdrawn, and since the coil 10 is alone insufficient to maintain the circuit breaker open, the contact 2 vibrates rapidly producing a series of interruptions the first of which suffices to extinguish the rectifier whose ignition circuit has previously been interrupted, whilst the interruptions are of sufficiently short duration as not to affect the consumer or the parallel operating rectifiers.

Abstract: 935,794. Semi-conductor devices. HUGHES AIRCRAFT CO. April 14, 1961 [May 2, 1960], No. 13591/61. Class 37. A junction transistor comprises a circular base region on which is eccentrically arranged an emitter region so that the two have a common outer surface. In the arrangement shown in Figs. 2 and 3, the circular N-type silicon base region 13 is formed by diffusion or alloying within a P-type silicon collector region 19 and contains a circular P-type emitter region 14 which is eccentrically arranged in the base region so that they have a common top surface. Connections to the emitter and base regions are made by gold alloy leads 15, 16 and to the collector by tantalum tabs 17. The purpose of the arrangement is to make the current leave the emitter radially and follow a low conductance path at constant current density to the base lead. Such a path is preferably obtained by increasing the radial distance from the emitter across the surface of the base region at a uniform rate from a point opposite the base lead to a point adjacent it and the present construction approximates this. The surface of the device may be doped more highly than the body of the base region reaching degeneracy at the surface and as described with reference to Fig. 5 (not shown), a metal coating may be provided on the surface of the base region around the emitter.

A particle collector arrangement in a mass spectrometer, spectrograph or separator comprises one or more semi-conductor detectors, e.g. of the surface-barrier-layer type, arranged for the simultaneous registration of several mass lines. The detector may be a lithium diffused silicon crystal provided with a high resistance backing layer preferably vapour deposited. In one embodiment, a single elongated detector is used, the heights of the mass lines as determined by the magnitudes of current impulses in a multi-channel analyser, being proportional to the length of the particle path through the detector which is longer for the more deflected, lighter particles. In another embodiment, an array of narrow semi-conductor detectors are arranged side by side and connected to a counter via a delay line to which the detectors are individually connected along its length. The difference in transit time between impulses appearing at the two ends of the delay lines provides an indication of the location of the semi-conductor detector on which a particle falls.
