IPC: B61L3/22
Filed: 1919-02-20
Abstract: 137,650. Thompson, H. A. Feb. 20, 1919. Track apparatus actuating signals on trains and for stopping trains.-A track circuit system for use with apparatus as described in Specifications 18443/14 and 12228/15 is a modification of the track system described in Specification 19123/14. Each circuit to a track wire 1, 4, 13 is supplied with alternating current from mains through a choking-coil. This choking- coil may have a core which is moved in conjunction with the signal, or may be independent of the signal, in which case the signal may operate a switch. The circuit may also be controlled by a track relay 12. For single-track working, currents of different frequency are used for each direction of traffic. The train coils may be wound as described in Specification 117,669. The track wire is laid alongside one track rail so that onlv one limb of the train-carried coil receives an effective induction. According to the Provisional Specification, the line-wires are central of the track, and the train coil is arranged to present only one limb to the electro-magnetic field.

A crimping device 124 may be provided, if necessary. The strips are passed through a coater 125 where a contact adhesive is applied. An elastic strip 16 is fed from a reel 127 and coated at its edges with similar adhesive in a device (128) (Fig. 6b, not shown). The coated strips are partially dried and the strip 16 is laid on the portions 23, 24 (Fig. 4, not shown) in a bonding machine (131) (Fig. 6D, not shown). The strips are finally bent to the shape shown in Fig. 2 by bonding rolls (132) and press rolls (133-135) (Fig. 6D).

Abstract: 178,979. Evans, L. T. Godfrey-. Feb. 8, 1921. Spray carburettors. - Liquid fuel under pressure is supplied past the needle valve 16 to a saucer 30 in a regulating-chamber 18. This chamber is connected to an air-vessel 29, the capacity of the vessel being adjustable by the plug 31. Air under pressure is supplied to the pipe 20 and part enters the vessel 29 through a side passage 26 and a non-return valve. While the admission port to the engine is closed the pressure in the vessel 29 rises, but when the admission port opens there is a fall in pressure at the outlet 21 and the air under pressure in the vessel 29 sprays the fuel through the nozzle 23, part of the air issuing with the fuel. The mixture passes by the baffles and cross tubes 24; the tubes are connected to a jacket 25 through which passes hot air, exhaust, water from the cooling jacket or steam. Baffles 22 ensure a circuitous air flow. The fuel is delivered from a tank by pressure obtained from the explosion in the working cylinder.

Abstract: 525,014. Purifying sugar. APPLIED SUGAR LABORATORIES, Inc. Feb. 11, 1939, No. 4542. Convention date, April 5, 1938. [Class 127] Raw sugar, before affination, is dissolved, defecated and chemically bleached to produce a refined syrup. The raw sugar is dissolved in water, calcium hydroxide is added to bring the pH to about 7.5 then phosphoric acid or dicalcium phosphate to produce a pH of 6.5 to 6.8. A small quantity of diatomaceous earth or kaolin may be added. The mixture is centrifuged, and the separated syrup may be treated with activated carbon and filtered. The filtrate is treated with calcium hypochlorite followed by acid calcium phosphate or phosphoric acid.

Title: Improvements relating to television receivers for colour images
IPC: H03L7/06
Filed: 1955-02-16
Abstract: 769,122. Automatic phase control systems. GENERAL ELECTRIC CO. Feb. 16, 1955 [Feb. 16, 1954], No. 4706/55. Drawings to Specification. Class 38 (4). In a colour television system the colour synchronized oscillator, to prevent pulling, operates at a sub-multiple of the frequency of the colour phase reference oscillation and its oscillation multiplied in frequency to that of the reference. oscillation with which it is compared in a phase discriminator with output controlling through a reactance valve the frequency and' phase of the oscillator. To this end the cathode and first two grids of a single pentode may act as an oscillator having an electroncoupled anode circuit tuned to a harmonic of the oscillator frequency. The phase comparison may be at R.F., I.F. or video level. In a modification, two oscillators of difference frequency equal to the reference frequency are employed, one being a crystal stabilized type, the other controllable in frequency and phase by a reactance valve, and their difference frequency obtained from a mixer circuit compared in phase with the reference frequency in a phase discriminator controlling through the reactance valve the controlled oscillator and hence the phase of the difference frequency.
