Abstract: 790,631. Electric indicating systems. KELVIN & HUGHES, Ltd. Jan. 2, 1956 [Dec. 14, 1954], No. 36149/54. Class 40 (1). A thermocouple instrument comprises a thermocouple 10 connected with an indicator circuit 12, a protective device 11 which applies a potential difference across the thermocouple so as to urge the indicator to full-scale reading on breakage of the thermocouple and a compensating device 14 which injects into the indicator circuit a voltage equal and opposite to the voltage developed across the thermocouple by the protective device when the thermocouple is unbroken. The protective device 11 comprises a transformer 15 the secondary of which is connected to a rectifier 16 which through a resistor 17 applies the potential difference to the thermocouple. The compensating device comprises a transformer 25 which through a rectifier 20 and resistor 21 is connected across a variable resistor 22 in the circuit between the thermocouple and the indicator. The rectifier 20 is arranged so that the voltage developed across the part of the resistor 22 in circuit is in opposition to the voltage developed across the indicator 24 by the protective device 11 and hence by adjustment of the resistor 22 the pointer of the indicator 24 can be adjusted to its neutral position. Since the transformers 15 and 25 are connected to the same mains supply balance is maintained irrespective of voltage fluctuations. A single transformer can be used instead of two separate transformers.

Title: Colour television circuit
IPC: H04N9/70
Filed: 1955-12-16
Abstract: 796,893. Colour television. SYLVANIA ELECTRIC PRODUCTS, Inc. Dec. 16, 1955 [Dec. 16, 1954], No. 36214/55. Class 40 (3). Normally non-conducting gate stage 71 employed to separate out the synchronizing " burst " signal in a colour television system of the subcarrier type is rendered conducting during the horizontal retrace interval by a pulse from winding 91 on the line-scan generator transformer 19, a connection being taken from the anode of the stage to the screen 49 of the colour channel amplifier 45, so that, at the same time, the amplifier is cut off by a reduction of its screen potential and the " burst " is prevented from entering the colour demodulator 32. The separated " burst " synchronizes the local subcarrier oscillator 34 by way of a conventional phase detector 103 and a reactance tube 36, and the bias to hold the gate 71 normally non-conducting is derived on load 123 from the negative potential produced at the anode of one of the diodes in the phase detector. The potential is due mainly to the " burst " signal, which greatly exceeds the local oscillator signal in amplitude, with the result that the bias largely disappears when the receiver is operated with a normal monochrome transmission. The gate then conducts continuously and holds the colour amplifier cut off to prevent the transmission to the picture display of noise and other disturbances which may be developed in or transmitted through the colour channel.

Abstract: 402,942. Oil-break switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 22, 1932. No. 36355. Convention date, Dec. 29, 1931. [Class 38 (v).] The oil employed in liquid-break switches has the air or oxygen removed and is then impregnated with carbonic acid gas. The air is removed from the oil by any known vacuum treatment and the gas is supplied either by blowing through the oil or by bringing the oil into finely divided particles which are passed under pressure into intimate contact with the gas. To increase the receptivity of the oil it may be heated or subjected to a pressure in excess of atmospheric pressure, the pressure and heating being effected in one or several applications. In use, if the switch detonates during operation the gas is suddenly and to a considerable extent freed from the oil and settles over the oil surface. Moreover, the products of the arc cannot ignite owing to the absence of oxygen. Any loss of the gas by diffusion in switches which are in communication with the atmosphere may be replaced by mixing with the oil a substance that gives off the inert gas.
