Patent GB-285537-A (GB)
Title: Improvements in or relating to vacuum electric tube devices
IPC: H01J1/18
Filed: 1926-11-09
Abstract: 285,537. Robinson, E. Y., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 9, 1926. Vacuum tubes.-Hairpin, zig-zag, or other filament electrodes comprising several straight portions connected by one or more bights are supported, registered or constrained at a bight by a wire or strip core which, near the bight, is of hook, eye, U, V or like shape and covered with electrically insulating material conforming to the shape of the core. The straight portions of the filament may also be restrained by insulating members. The core may be secured in electrical connection with another part of the filament circuit such as the framework described in Specification 285,536, or with another electrode, such as a space-charge grid, acting as a framework, or may itself be insulated and embedded, for example, in a glass bead supported from an anode support. The covering is heat insulating and increases the efficiency of the filament, periodic cooling of a filament freely supported at its bight and not under tension being also avoided. The covering may be fused, sintered, melted or formed on the core during or after the shaping of the core. A molybdenum or tungsten hook or an eye may be repeatedly dipped in a kaolin or porcelain slip such as a suspension in water of 3 parts of porcelain to 1 of kaolin, the coating being dried in a flame after each dipping and finally fused in a blow-pipe flame. A straight wire and a surrounding quartz tube may be bent together in a flame. In modifications, a flat strip for registering hairpin filaments as described in Specifications 222,176 and 273,394 may be coated with insulation at its hooked end or the strip may be replaced by a wire 8, Fig. 3, with an insulating covering at 11 and supported by a strip 9 and wire 10. The filament may be assembled as in Specification 273,394. A W-shaped filament with its two halves in parallel may be supported at two bights by covered hooks as in Specification 285,536. A zig-zag filament 36, Fig. 10, may be supported in a framework comprising metal parts 34, a temporary cross-member 32 and a glass bead 35, the bights of the filament being supported by wires 40 with indentations 41 covered with insulation and the parts 34 finally acting as current leads. The wires 40 may be replaced by covered hooks welded to the parts 34. In a further modification with small interelectrode gap, the covered hook 71, Fig. 11, is supported by a wire 72 welded to channel-shaped parts 69 of a grid. The filament is constrained at the centre by an insulating covering on two adjacent grid wires or on wires 73 welded to the parts 69 and pressed together. The filament may have a preliminary sheath of another metal and be coated with oxide as in Specification 285,538. Specification 1694/15 also is referred to.

IPC: D06F58/28
Filed: 1961-08-03
Abstract: 972,411. Washing and drying machines. BORG-WARNER CORPORATION. Aug. 3, 1961, No. 28293/61. Heading D1A. A washing and drying machine of the horizontal rotary drum type has a perforate drum 18 provided on its outside with a pair of V-shaped scoops 77 which at some stage during the washing cycle scoop up water from the tub 11 to flush accumulated lint from the drum. The drum 18 is supported on a spider 19 mounted on a hollow shaft 20 and driven by a motor 28 via belts and a two-speed transmission 24. The front of the drum 18 has a flange 37 which is supported by a plurality of rollers 38 mounted on the front wall 12 of tub 11. Air may be circulated through the drum 18 by means of a fan 39, positioned within the spider 19 and behind a perforate screen 48 and attached to a shaft 42, which is mounted within the shaft 20 and is driven by the motor 28 via belts. This circulating air may be heated by a heater 49 comprising heating coils 51 between baffles 50 and vapour is condensed from the air by contact of the air with a plate 126 at the rear of the tub which is cooled by a stream of cold water from nozzles 121a and 121b. Hot, cold or warm water is provided by a solenoid operated mixing valve 62 and is supplied to the drum through a spray nozzle 61. Water is discharged from a sump 67 below the tub by a pump 68 driven by motor 28 through a solenoid operated drain valve 70. Also at the bottom of the tub is a pressure sensitive switch 75 which controls the liquid level. Either washing or drying or both may be provided by means of a wash timer WT and a dry cycle switch D T. Operation, A typical sequence of operation of the machine is as follows. The drum is driven at slow speed, the drain valve 70 is closed and the mixing valve 62 is set to supply hot water until the switch 75 turns off the water supply and starts the wash time when the tub is full. Slow speed rotation continues for a twelve minute washing after which the drain valve 70 is opened, and water is supplied for two minutes to break up the suds. The water is then turned off for one minute to distribute the washing evenly and it is then turned on again for a four minute spray rinse at the end of which one minute of high speed spin is provided. Another spray rinse is provided at the end of which the drain is closed to give one minute deep rinse. The drain is then opened during a two minute high speed spin and then closed again. Three gallons of water is then added and the drum is set to high speed spin so that the scoops 77 pick up the water distribute it vigorously to flush off accumulated lint which is then removed from the machine when the drain is opened again. The fan 39, the heater 49 and a supply of cold water to nozzles 121a and 121b are then switched on while the drum is rotating at slow speed to perform the drying operation. The length of this operation is controlled by a thermostat 116, as the temperature of the circulating air is constant until the washing is dry, and then it rises suddenly operating the thermostat 116.
