Title: Cooking apparatus
IPC: A47J37/04
Filed: 1962-11-07
Abstract: 969,983. Cooking apparatus. KENTUCKY FRIED CHICKEN Inc. Nov 7, 1962 [July 16, 1962], No. 42117/62. Heading A4D. In an assembly of cooking and warming appliances, especially for cooking chickens in fat or oil under steam pressure, a filter 15, for the oil, is arranged on the opposite side of a pressure oven 11 to a warmed serving table 18 and a transfer table 23 enables a pan to be readily moved between all the appliances and a pre-heater 30. A deep pan supported on rollers 56 of carriage 50 is filled with filtered oil from tank 81 by pump 78 which is detachably mounted on the tank. To start cooking, carriage 50 is moved on rollers 53 away from filter 18 to bring the pan into alignment with chain conveyer 43 of pre-heater 30. The pan is slid off the carriage and moved by handle 44 on to the pre-heater. The oil is heated to cooking temperature by gas-burners arranged between chains 43 and when hot the chickens are immersed in the oil. The pans are then moved, by operating handle 44, across carriage 50 and on to a set of rollers mounted above the floor of oven 11. After closing and latching the oven door, steam is admitted and the desired temperature and pressure are maintained to complete cooking. The pin is thereafter pulled out of the oven on to carriage 50 and the carriage moved in front of serving table 18. The chickens are lifted out of the pan and allowed to stand on draining board 63 which is heated by infra-red lamp 65a. The excess oil drains to outlet 20. The screened suction pipe 72 of pump 67 is immersed in the pan and the oil is pumped back into the filter 18. In other forms, three pre-heaters serve a single oven and these may be arranged side-by-side (Fig. 28, not shown) or radially, on an electrically indurable turnable, (Figs. 30-32, not shown). The gas pre-heating may be replaced by electric heaters pivotally mounted on tank 81 (Figs. 16 and 17, not shown) and electric heating elements may be provided in the bottoms of the pans (Figs. 18-20, not shown). An electric motor may replace handle 44 (Figs 28, 30, 31 and 2a, not shown).

Abstract: 1520285 H.T. supplies for cathode ray tubes SONY CORP 16 Oct 1975 [21 Oct 1974] 42497/75 Heading H2F A circuit for supplying a high D.C. voltage to the anode of a cathode ray tube comprises a flyback transformer 7 having loosely coupled primary and secondary windings 7a, 7b, the primary winding receiving a signal at the horizontal deflection frequency and the output resonant frequency of the transformer being higher than the horizontal deflection frequency, and a rectifier 9 for rectifying the substantially sinusoidal voltage across the secondary winding to produce a regulated high voltage D.C. signal. A D.C. source is connected to a terminal 8 and the horizontal deflection signal is coupled to the base of a transistor 2 so that the primary winding 7a receives pulses at the horizontal deflection frequency of 15À75 kHz. The inductances of the windings 7a, 7b, a tertiary winding 7c and a horizontal deflection coil 5, the capacitance of a capacitor 12 and the coupling coefficients of the windings are selected so that the output resonant frequency of the transformer is 20 kHz. This causes the transformer output to be sinusoidal but having a flattened peak thereby increasing the conduction angle of the rectifier 9 and improving the regulation of the high voltage at the output terminal 10.

Abstract: 1,097,585. Viewing inside of pipes. PYE Ltd. Oct. 20, 1964 [Oct. 30, 1963], No. 42737/63. Heading H4F. A television camera arrangement for viewing the inside of a pipe through which it is moved comprises an electron tube for converting visual images into electrical impulses, and a lens assembly adapted to focus visual images on the tube, the lens assembly being pivotally-connected with the tube so that the central plane of the lens assembly may be maintained substantially normal to the wall of the pipe even at relatively sharp bends in the pipe so that the whole of the inside wall of the pipe may be viewed (explained with reference to Fig. 1, not shown). As shown, a complete inspection assembly for pipe interiors comprises a light source 20 and three pivotally connected sections, i.e. a camera tube 9, lens or lenses 10 and a head amplifier 11. Sections 10 and 11 are linked to the main body of the camera 9 by means of gimbal joints 12 and 13, one pivotal axis of gimbal joint 12 lying in the plane of the pick-up tube face in order to ensure that the distance between lens centre and tube face along the optical axis of the lens remains constant. The light source 20 is attached to the camera by means of a spring steel wire hitch 16 which passes through diametrically opposed lugs 18 on a rotatable washer 19 and is secured by screws 17 to body 9, the wire hitch having two helical portions as shown so that if any binding takes place at the front of the camera the helices unwind, washer 19 rotates and the towing force is applied directly about the centre of body 9 reducing the pivotal length to a minimum and inclining the lens assembly 10 towards the inner wall of the bend. Two conical members arranged base-to-base having reflecting surfaces 22 and 23 are supported by wires 24 which form a protective cage around bulb 21. Reflecting surface 22 reflects light on to the wall of the pipe and prevents light falling directly upon the lens assembly and reflecting surface 23 enables the camera to view perpendicularly a section of the interior wall. The complete assembly is towed through the pipe by means of cable 26 which carries a low voltage supply to the bulb. Cable 15 carries the power to energize the pick-up tube and head amplifier, camera control signals and the video signals from the output of the head amplifier.
