Title: Improvements in or relating to automatic block signalling systems
IPC: B61L23/16
Filed: 1932-03-03
Abstract: 383,833. Electromagnetic relays. MEYER, K., 51, Reichsstrasse, Charlottenburg, Berlin. March 3, 1932, No. 6482. [Class 38 (v).] In a railway signalling system in which track relays M are fed over the rails with alternating current from a transformer B in series with the lamp signals of the section ahead, the relays can only lift their armatures when the danger lamp signal current flows, this current flowing through the full transformer primary winding to apply full voltage to the rails ; the clear lamp signal current flows only through part of the transformer winding but the resulting lower rail voltage is sufficient to hold up the relay armature. The altered impedance of the relay with its armature lifted is compensated by the relay opening a contact 52 to cut out one of two..paralleled condensers C31, C32 in series with the relay or by the relay closing a contact to shunt a series choke, Fig. 4 (not shown), and so to maintain approximate resonance.

Title: Improvements relating to semi-conductor arrangements
IPC: H01L29/00
Filed: 1954-03-09
Abstract: 786,876. Semi-conductor devices. GENERAL ELECTRIC CO. March 9, 1954 [March 9, 1953], No. 6859/54. Class 37. [Also in Group XL (c)] A trigger circuit comprises a semi-conductor body 12 of one conductivity type with an ohmic connection 13, 15 at each end and a trigger electrode 25 of the opposite conductivity type forming a PN junction 27 with the body between the ends, means for applying similarly poled bias voltages Vs, Vc between the ohmic connections and between one of them and the trigger, and means for varying the relative values thereof to control the device between states in which the junction is forward and reverse biased respectively. The body may be a single crystal of N (or P) type Ge or Si and the trigger electrode formed by a pellet 23 of In (or donor impurity) fused thereto in the centre of one face of the body. When the voltage Vc applied to the trigger is much less than ¢ Vs the voltage in the N-type material adjacent the junction is such as to reverse bias it, and when Vc is much greater than ¢ Vs the junction is forward biased. If Vc is such that the voltage of the P material is ¢ Vs, one end 37 of the junction is biased as an emitter and the other 39 as a collector. If the dimensions of the body are suitably chosen this condition is unstable since the minority carriers injected by the emitter into the left-hand end of the body reduce its resistivity to such an extent that the zero bias point on the junction moves away from electrode 13 until the entire junction functions as an emitter when stability is again reached. This negative resistance feature is used in the trigger circuit shown in Fig. 10, in which the voltage of bias source 29 is such as to reverse bias the junction. A similarly poled variable control voltage Vp may bring the device to its unstable condition whereupon relay 41 operates to complete (or open) a circuit to the controlled device 57. In an otherwise identical circuit the control voltage is in series opposition with the source 21 producing the voltage gradient in the body. Specification 728,129 is referred to.

Abstract: 589,213. Two-part couplings. DORMAN & SMITH, Ltd., and ATHERTON, T. March 20, 1945, No. 6963. [Class 38 (i)] The use of a wrong plug and the incorrect insertion of a plug having a fused pin as described in Specification 566,384, are prevented by providing complementary engaging parts in the plug and socket connection. In Fig. 9 a three-pin plug has an enlarged " neutral" pin 23 which engages a correspondingly enlarged socket contact so that it cannot be inserted in a " live " contact accidentally. In Fig. 2, the earth " pin 16 has a groove 17 which co-operates with a projection in the socket contact, Fig. 3, (not shown), in the socket cover, Fig. 4, (not shown). In Figs. 5-8, (not shown), a specially chamfered " earth " pin on the plug rotates a protective shutter in the socket to expose the contacts and permit the insertion of the plug. Fig. 12 shows a plug with a recess 26 into which a socket projection 25 enters when the connection is made. In Figs. 14, 15, (not shown), a flange on the socket cover embraces and guides the plug. The spacing of the pins, Fig. 11, (not shown), may alternatively be non-standard. The Provisional Specification refers also to an additional shutter operated by the neutral pin, and to earth-pins of triangular section or having triangular bores entered by corresponding pins in the earth-socket.
