Title: Improvements in and relating to electrical heating apparatus
IPC: H01H37/36
Filed: 1956-12-21
Abstract: 798,922. Sheathed heating resistors. GENERAL ELECTRIC CO. Dec. 21, 1956 [Dec. 27, 1955], No. 38962/56. Class 39(3) [Also in Groups XIII and XXXVII] A sheathed heater with a coiled wire resistor 2 within a tubular sheath 1 from which it is insulated by magnesium oxide or alumina or magnesia cement has an elongated argon-filled teperature responsive tube 4 extending longitudinally within the sheath, one end of the tube 4 projecting through a washer 6 out of one end of the sheath and communicating externally with a diaphragm or bellows 12 for sensing the inner temperature of the sheath. The tube 4 extends within the heating coil 2 and may be metal, so that current may be supplied to one end of the coil 3 by a terminal 7 at one end of the sheath and to the other end of the coil through the tube 4 connected to the coil by a metal sleeve 9. The bellows 12 carries or operates a movable contact 14 of a switch open-circuiting the heater on rise of temperature. Thermostatic cycling action of the switch may be obtained by mounting its other contact 15 on an over centre device i.e. on a bowed spring 21 with its ends in opposed openings in a casing 11 and passing through opposed slots, 19, 20 in a rectangular contact actuator 18 of non-conducting material mounted on the bellows 12. A spring 17 bears on the lower side of the actuator 18 to oppose the bellows 12, and as the heater cools the spring 17 presses the actuator 18 up so that the bowed spring 21 snaps over centre to engage contacts 14, 15 and so pass current to the heater coil 2 either through the bellows and tube 5 or through a wire connected between the contact 14 and coil 2. When the tube 5 and its exter nal projection 13 are of metal, the part 13 is covered with insulation 16. On rise in temperature of the sheath, the bellows 12 expands to push the spring 21 over centre and open the contacts 14, 15. Spring 17 rests on a collar 22 positioned on a cam 23 actuated by depressing a bush button 24 to push the spring 21 over centre to commence heating. To prevent overheating of the sheathed unit should contacts 14, 15 fail to open, the switch actuator 18 moves down to engage the end of a plunger 17 having on its lower end a contact 25 bearing on a contact 26 on a bowledspring 28, which is thus forced down to over centre position to open the contacts 25, 26 as shown. This spring 28 may be reset by a push button 29 in the bottom of the casing 11. The sheathed heater may be a surface unit on a cooking range. By providing several different cams 23a, 23b each with a separate push-button 24, various temperature settings for the heater may be obtained. The heating is ended by pulling out the push-button.

Abstract: 827,692. Melting glass. OWENS-ILLINOIS GLASS CO. Dec. 20, 1957, No. 39755/57. Class 56. [Also in Group II] In a method of controlling convection currents in a body of molten glass or metal having a bubbling nozzle communicating with a lower level of the body, a predetermined volume of gas under substantial pressure is periodically injected through the nozzle to form individual bubbles in the body, and a substantially lower pressure in the nozzle is maintained at least during those periods intermediate the delivery of the predetermined gas volumes to prevent the entry of molten glass or metal into the nozzle. As shown low pressure gas is continuously passed from tank 20 through pipe 21, manifold 18, conduit 19 into chamber 34 of bubbler tube assembly 32, the pressure setting of regulator 26 being such that the pressure maintained in tank 20 balances the pressure head exerted by the molten glass G on bubbler nozzle 13. High pressure gas is supplied from tank 22 to the manifold 16 and conduit 17 into the inlet side of valve 31 normally maintained closed by a spring or other closing means to block the flow of gas into chamber 34. A timer control 39 is set to actuate the solenoid 38 at timed intervals to open valve 31 and permit high pressure gas to flow into chamber 34, central core 36 and bubbler nozzle 13. After a predetermined time lapse, timer control 39 deenergizes solenoid 38 and valve 31 again closes to block off the flow of gas into chamber 34. Thus, by rapidly intermittently opening and closing valve 31 measured volumes of high pressure gas are injected into the bubbler tube 14 and exploded at bubbler nozzle 13 to form enlarged gas bubbles A at the bottom level of the molten glass contained in melter 10.

Abstract: 1361995 Cinematography AGFA-GEVAERT AG 27 Aug 1971 [27 Aug 1970] 40310/71 Heading G2E  A cine camera includes a drive mechanism for a film reel deriving its motion from the intermittent feed mechanism. As shown a member 7 pivotally mounted at 6 carries two pawls 8, 9 which can engage gear 4 mounted on a shaft connected to a film reel. A motor driving a film feed claw causes part 2, which is connected to the claw, to reciprocate between the positions shown. This transmits its motion via spring 12 and a stop 7b to the member 7 which rocks about 6. The pawls 8, 9 are arranged to drive the gear 4 in an anti-clockwise direction (as viewed) and to slide over the teeth of the gear when moving in a direction which would not produce such a direction of rotation. This is achieved by the use of a U-shaped end 7a of the member 7 so that when the part 2 moves in the direction of the arrow, spring 13 urges the member 7 towards the gear 4 and the pawl 9 rotates the gear 4. Then when the part 2 returns to the position shown, causing the spring 12 to move the member 7 away from the gear 4 against the action of the spring 13, the pawl 8 rotates the gear 4. If the shaft 3 refuses to rotate (e.g. when the reel is fully wound) then the movement of the part 2 is absorbed by the spring 12.
