Title: Improvements in or relating to colour television systems
Inventor: BEDFORD LESLIE HERBERT
IPC: H04N9/44
Filed: 1953-11-26
Abstract: 745,322. Colour television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 15, 1954 [Nov. 26, 1953], No. 32913/53. Class 40 (3). In a colour television system in which luminance and chrominance signals are transmitted as modulations of different carrier frequencies Fy, Fc, the two signals occupying bands of frequencies adjacent to, but spaced from, one another, a pilot frequency Fp is transmitted midway between the luminance and chrominance carriers and serves at the receiver to provide a signal of reference frequency and phase for demodulating the chrominance signal. Accompanying sound signals are transmitted on a carrier Fs and the pilot Fp is also employed for demodulating this signal. The invention is described as applied to a system in which the chrominance signal is in the form of quadrature modulations of carrier Fc by " I " and " Q " signals in accordance with the American M.T.S.C. standards. At the receiver, Fig. 7 (not shown), after conversion to an intermediate frequency, the received signals are applied to two channels. In the first of these, which has a pass-band including Fs, Fy and Fp, the luminance signal component is selected and applied to a detector to derive the luminance signal. The sound component is also separated in a timed detector as the 4.8 Mc/s. beat frequency between the sound and pilot carriers. Thereafter a detector recovers the sound signal. In the second channel, which has a pass-band including Fy, Fp and Fs, the received signal is detected and the chrominance component extracted and applied to a synchronous detector. The signal is also applied through an amplifier having a response peaked at Fy and Fp to a detector from which the 1.3 Mc/s. beat signal between Fy and Fp is separated. This signal then provides the reference signal for the synchronous detector and is either doubled in frequency and employed directly to effect demodulation or is employed to control a local 2.6 Mc/s. source.

In a heating system, radiation means adapted for connection with, or disconnection from, a heating fluid supply circuit by means of a thermostatically controlled valve arranged to be operated by a motor-driven cam. As shown, a motor 22 positioning a valve, connecting a radiator in a zone to a hot water supply, is energized from a transformer 44 via switches 28A, 28B in series. The switches are alternately operated by apertures 30, 30<SP>1</SP> in a gear 25 driven by the motor, the switch 28B being open when the valve is open. A thermostat T tends to maintain the temperature in a zone constant by short-circuiting switch 28B when the temperature is below a desired value to cause the motor to open the valve until the switch 28A is opened. For an excessive temperature the switch 28A is short-circuited by the thermostat and the converse switching sequence occurs.- When the valve is closed arcuate apertures 30A, 30B in the gear 25 open a switch 29 to deenergize a relay 42. Contacts 43 of the relays for the plurality of zones are connected in parallel so that a motor 35, driving a steamcirculating pump 31 is disconnected from a supply P1, P2 where there is no zone valve open The valve can be a plug or poppet valve.

Title: Improvements in or relating to a process for the pyrolysis of hydrocarbons and apparatus for carrying out the process
IPC: C07C4/02
Filed: 1954-11-23
Abstract: <PICT:0763561/IV(b)/1> A process for the pyrolysis of hydrocarbons which are less unsaturated than acetylene to form more unsaturated hydrocarbons particularly acetylene comprises introducing the hydrocarbon transversely into the hot gases of combustion of a flame having a high oxyhydrogen content, the introduction taking place in a pyrolysis chamber and the flame being formed in a combustion chamber, both chambers having metallic walls which are externally cooled by the circulation of cold water.  In a preferred apparatus, fuel such as hydrogen, methane or coke oven gas is fed to a tube 1 (Fig. 1a) and oxygen (or air highly enriched in oxygen) fed to a tube 2, the mixed gases being introduced through an injector 3 into a combustion chamber 4 where the mixture is ignited.  At a point beyond the zone in which the flame ceases to exist the chamber 4 is continued in a conduit 5 which forms a pyrolysis chamber.  The hydrocarbon to be pyrolysed is passed through a ring 6 into nozzles 7 leading to orifices 7a.  Water is injected through atomizer 9 in a direction transverse in relation to the current of gases.  The whole is surrounded by a water jacket 10.  In a modification (not shown) the hydrocarbons to be treated are also fed to a central distributer and are distributed outwards.  Specification 264,845, [Class 2 (i)], is referred to.

Abstract: 471,888. Tobacco. AZARIAN, A. Dec. 9, 1935, No. 34116. Convention date, Dec. 10, 1934. [Class 130] To improve its quality and aroma and to reduce the nicotine content, tobacco is subjected, preferably with the exclusion of air, to an artificial fermentation by adding a fermentation accelerator consisting wholly or mainly of essential oils, the temperature being raised to 25‹ C. or more, and the fermentation process being repeated one or more times with intermediate admission of air and cooling. The fermentation accelerator mav consist of pure anethole or aniseed oil or a mixture of both. For the final stage of treatment, a mixture of aniseed oil, anethole, amber oil, cognac, cinnamon oil and lemon oil in water may be employed. For inferior and diseased tobaccos the treatment may be carried out at a temperature of 60-70‹ C. In the apparatus shown in the Figure, the tobacco is placed between perforated end walls 4, 5 in a drum 1 rotatable in end supports 2, 3 and provided with a thermometer 25 and a moisture indicator 26. The treating liquid is contained in a receptacle 19 provided with an electric heater 23, a thermometer 21 and a pressure conduit 24 and is introduced into the tobacco through a perforated tube 14. The drum is closed in an air-tight manner and slowly rotated by a motor, while heated to 25 or 30‹ C. by means of steam or hot air admitted to a jacket 9. Liquid from the container 19, heated to 35‹ C., is sprayed in through the tube 14 while the tobacco is heated to 35‹ C. After some hours, the heating is stopped and a cover 28 opened to admit air while the drum is slowly rotated. The drum is then stopped, the cover 11 opened and air blown through by the fan 8. The tobacco is allowed to stand for 5- 6 hours and the drum is again closed and the treatment repeated.
