Title: Improvements in or relating to electric signalling systems
IPC: H02J13/00
Filed: 1938-07-19
Abstract: 511,812. Electric control systems. STANDARD TELEPHONES & CABLES, Ltd. (Material Telephonique, Soc. Anon.). July 19, 1938, No. 21419. [Class 40 (i)] In a system for effecting alternative controls over a two-wire channel by phase reversals of an A.C., and more particularly for controlling the application of positive or negative D.C. impulses to an electric power network at a substation, two relays PR, NR at a substation CDS are connected in rectifier circuits RA, RB and are connected in circuit with transformers T2, T3 supplied from a transformer T1, and having secondary windings connected to the ' pilot wires in parallel and in phase opposition through rectifiers RC, DD. The rectifiers apply unidirectional pulses to the pilot wires, alternate pulses being generated by the transformer T2, T3 respectively. A transformer T4 at the control station CGS is adapted to be connected across the pilot wires in one direction or the other under the control of relays PRS, NRS, the arrangement being such that one or other relay PR, NR is operated in dependence upon the phase relations of the voltage of the transformer T4 and the alternate impulses in the pilot wires. When a relay is operated a check signal is sent by relay B which reverses the polarity of the impulses in the pilot wires and pulls up relay CK to release a relay CKA which is locked up when one or other of the relays PRS, NRS is operated to transmit a control pulse. If due to faulty operation of the receiving equipment relay B is not operated and a checking pulse is not reverted to the station CGS, relay CKA remains locked up upon the termination of the control pulse and causes operation of relay F which operates a lamp and an alarm at contact f2, f3. An additional control may be effected by simultaneous operation of the relays PRS, NRS to loop the line wires at the control station and thereby cause operation of both relays PR, NR.

Abstract: 715,826. Changing wave shape. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 5, 1952 [Sept. 14, 1951], No. 21661/51. Class 38(2) A source G of A.C. supplies a load R through series connected inductor L and capacitor C which are resonant at the supply frequency, and a capacitor D with a non-linear dielectric such as barium titanate is connected in parallel with R so that each half cycle, as the current flowing through the circuit GLCD reaches its maximum value, the dielectric saturates and the consequent great increase in impedance of D results in the development of a sharp voltage pulse across load R. Alternate pulses may be suppressed by means of rectifiers, or the positive and negative pulses may be separated into different circuits by using a pulse transformer with two secondary windings each connected to a rectifier. The phase relationship between consecutive pulses may be varied by connecting a source of biasing voltage in series with a blocking capacitor across capacitor D. The necessary properties of capacitor D for correct functioning, are stated.
