Title: Improvements in gas cookers
IPC: F24C3/12
Filed: 1939-08-31
Abstract: 535,180. Gas-cookers; mounting burners. HIBBERD, H. C. Aug. 31, 1939, Nos. 25023 and 25024. Convention dates, Aug. 31, 1938, and Dec. 1, 1938. [Classes 75 (i) and 126] On the door of a gas-cooker being opened the combustion gases from the burner, instead of passing into the oven, are directed into an exhaust conduit. In the cooker shown the hot gases from the burner 4 enter the oven through a slot 2 and normally circulate therein in the manner shown by the arrows before passing through an opening 17 between a pivoted plate 6 and the edge 13 of a false bottom 10 forming a conduit 11 leading to the outlet 15. Some of the gases may escape through holes 18 in the false bottom 10. When the oven door 3 is opened a projection 16 on the door releases the plate 6 and allows it to swing on its pivots 8 to close the opening 17 and cover the opening 2, thereby causing the burner gases to enter the conduit 11 directly. The gas supply pipe to the burner may be fitted with a valve operated when the door is opened to reduce the gas supply or, if the burner is fitted with a pilot light to cut off the gas supply. The pipe may also be fitted with a thermostatically controlled valve. In another construction the opening of the door allows a spring-pressed rod to turn the burner about a horizontal axis to direct the gases into an exhaust conduit without entering the oven.

Abstract: 1391798 Colour television tubes RCA CORPORATION 31 May 1972 [14 Jan 1972] 25386/72 Heading H1D A static convergence device for a shadow mask tube using three co-planar beams comprises a quadrupole magnet for producing opposite effects on the outer beams without affecting the central beam, and a sextupole magnet for producing similar effects on the outer beams. Preferably there is also a two-pole magnet for producing similar effects on all three beams to adjust colour purity. Each magnet may comprise a pair of permanent magnetic rings, relative movement of a pair adjusting the magnitude of the effect and common movement adjusting the direction of the effect. If a pair of electromagnets are used, rotation is unnecessary since adjustment of the magnitude and direction of the current in each magnet allows for all possible adjustment of the magnitude and direction of the effect on the beams. The rings should be mounted round the neck of the tube preferably with the quadrupole magnet nearest the deflection yoke, the sextupole magnet in the centre, and the bi-pole magnet on the remote end of the tube. Preferably a low permeability material such as barium ferrite is used for the magnet rings to minimize interactions with the deflection fields, but if the purity rings are remote from the deflection yoke they may be of, cheaper material such as steel.

Abstract: 479,210. Burners for refrigerator cabinets. ELECTROLUX, Ltd. Sept. 18, 1936, No. 25449. Convention date, Sept. 27, 1935. [Classes 75 (i) and 126] The gas or oil burner, burner chimney, or similar burner member of a heating device for a refrigerator cabinet is lowered automatically during the insertion of the heating device into the cabinet and is raised by a spring when the heating device reaches its correct position. The heating device shown is in its operative position in a compartment formed by walls 12, 14 below a refrigerator cabinet 10 and comprises an oil container 20 fitted with a wick burner 21 which can be depressed against the resistance of a spring 24 by claws 29, 30 on a rod 26 fitted with an operating handle 27. During insertion of the heating device an extension 31 of the rod 26 engages a bent guide bar 40 mounted on the side wall 12 and causes the depression of the burner until the burner is beneath the flue 25 of the boiler 23, when the extension 31 reaches a vertical part 40a of the bar 40. The burner 21 consequently moves upwards until its chimney 22 engages the lower part of the boiler. The bar 40 may be formed with an arch 41 to lock the heating device in this position until the extension 31 is lowered by the handle 27 for its withdrawal. The arch 41 may be so formed as to exert a braking force on the upward movement of the burner or the impact of the chimney against the boiler may be lessened by inclining upwardly the bar 40 adjacent to the vertical part 40a. The filling device 16, the oil level indicating device 18, and the wick-operating device 17 are arranged at the front of the reservoir. The front wall 15 of the heating device compartment is fitted with a window 44 and is attached to the oil container. The sides of the compartment are formed with outwardly inclined portions 42, 43 to admit air to the flame and may serve as lateral guides for the reservoir. If desired, the heating device may be arranged to swivel in circular guides instead of moving longitudinally.
