Abstract: 1,263,683. Valves. ALFRED TEVES G.m.b.H. 7 Jan., 1970 [16 Jan., 1969], No. 826/70. Heading F2V. A spring-loaded relief valve which permits excess pressure in either space A or space B to be relieved, has a closure member 5 with an extension 9 that projects through the seat 3 and has a longitudinal bore 19. A change-over valve has a closure member formed of two balls 15, 15<SP>1</SP> joined by a cylinder 14 and seating on a seat 17 formed on the housing or a seat 16 at the end of bore 19 so that according to the pressures in spaces A and B the change-over valve moves to connect chamber 20 with either space A through bore 28 or space B through bore 19.

Title: Improvements in or relating to electric carrier signalling systems
IPC: H04B1/30
Filed: 1934-01-10
Abstract: 426,437. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BLIGH, N. R., c/o General Electric Co., Wembley, Middlesex. Jan. 10, 1934, No. 966. [Class 40 (v)] In a receiver for modulated carrier waves in which selectivity is obtained by mixing a local oscillation with the modulated carriers to produce the signal, complete separation of the original frequencies from the combination frequencies is achieved by the use of a pair of peak rectifiers with the local oscillation applied to a common part of their circuits and the incoming signals applied to the rectifiers in push-pull and filtering means, to include frequencies above a predetermined limit. Fig. 2 shows a pair of diode detectors 1, 2 with the local oscillation applied by transformer 8 and the incoming signal through the transformer 3 and the audio output taken from the resistance between A and B. In a modification, Fig. 4, the load resistance is shunted by a single condenser and is arranged in the common portion of the circuit and the filter 4 is in the output of the audio amplifier 13. A push-pull audio-amplifier, (Fig. 5b not shown), may be used with the midpoint 6 of the resistance connected to the cathodes and the points A, B to the grids. When two valves are used with their cathodes connected, they may be replaced by a multiple valve and the introduced oscillations may be of constant frequency, the means for producing coincidence with the required carrier being the local oscillator in a superheterodyne receiver. The local oscillation may be obtained by a filter in which high selectivity is obtained by the use of a piezoelectric crystal or reaction.
