Abstract: 402,412. Thermal switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, TURNER, H. C., and SHERWIN, A., Peel Works, Silk Street, Salford, Manchester. March 31, 1932, No. 9268. [Class 38 v).] In a thermal switch employing a member adapted through lateral deflection dependent on temperature variations to effect control of a switch contact, this member is mounted at one end on a fixed support and the relative positions of the fixed support and the said member are adjustable by a cam mechanism for the purpose of setting the switch for operation at a selected temperature. As shown in Fig. 2 the bimetallic strip 11 carrying the contact 12 is secured to an angle-shaped member 10 pivoted on a pin 9 passing through a fixed U-shaped supporting frame 3. A screw and lock nut 14 adjusts the position of the member 10 relatively to an arm 15 on the opposite side of which bears a sliding rod 16 the other end of which rests against a cam surface 17 formed on the inner face of an adjusting knob 18. The bimetallic strip is held away from engaging the fixed contact 1 by means of a spring 22 so that by adjustment of the cam against this spring the distance between the contact on the bimetallic strip and the fixed contact and consequently the temperature at which the contacts are brought into engagement, may be varied. The contacts are disposed between the poles of a horseshoe permanent magnet 3 and the bimetallic strip carries an armature 13 between the poles of this magnet which ensures a quickbreak action and a rapid suppression of arcing between the contacts. The contacts are surrounded bv an arc chute 8 of ceramic material. The switch may be surrounded by a liquidlight cover 26 the leads of the switch passing to external terminals 20.

Title: Method of and means for generating electromagnetic waves
IPC: H02K57/00
Filed: 1923-04-05
Abstract: 218,386. Rees, D. W. April 5, 1923. Oscillation generators; homodyne receiving systems. - E l e c t r o magnetic waves of frequencies varying from 3 x 10<4> to 3 x 10" are generated by the interaction of magnetic fields moving relatively to each other in a gaseous medium, usually at low pressure. The frequency increases with the intensity of the magnetic fields, and with the speed of their relative movement, and also varies with the frequency of the chief spectroscopic bands of the gas employed. The relative movement may be obtained by the rotation of one of a pair of magnetized structures or by supplying multi-phase alternating current to stationary structures. Fig. 1 shows an apparatus suitable for the generation of visible waves. The stationary magnetic system d, comprising a ring with pairs of electromagnets of opposite polarity, is mounted within a stationary air-tight glass cylinder a with metallic end covers c, and with suitable lubricating devices for the bearings of the shaft b. The rotary system comprises a core x with serrated flanges lying opposite the magnetic poles d and surrounded with coils h to which current is conveyed by slip rings r. The waves radiated from the plane of interaction of the magnetic fields are reflected from adjustable mirrors such as m or p<1>, which may be connected to a high-voltage generator so as to cause a discharge between them and suitablyplaced anodes. The moving system may be rotated by means internal to the cylinder a, which may be surrounded by liquid of appropriate colour or refractive index. Plane, circular, or elliptical polarization of the waves is stated to be secured by varying the angle between the interacting magnetic fields. Fig. 2 shows an apparatus for generating waves of radio frequency. The external stator 3 and the internal rotor 4 are arranged substantially as in alternating-current dynamos, and to each pole of the stator is attached an exhausted tube 1 containing a metallic conductor 2. These conductors are connected alternately to points of opposite potential in a radiating or other oscillatory circuit. Instead of employing separate vacuum tubes 2 for the conductor 1, the conductors 1 may be carried on the rotor which is then enclosed in a glass cylinder interposed between the rotor and the stator. Current is in this case collected from the conductors 1 by means of slip rings. As the presence of extraneous waves, of the same frequency as those generated by the machine, causes an increase of current strength, the machine may be used as a wireless receiver. With low intensity of the magnetic fields and low speed of rotation, and with air of atmospheric pressure as the gaseous medium, waves of audible frequency are produced.

[Also in Division H1] In order to reduce the dimensions of high voltage installations such as isolators, busbars, circuit-breakers, &c., the high voltage component or components are insulated by enclosing them in a gas having a dielectric strength greater than that of air which is confined around the component by a thin insulating envelope. The leads to the high voltage components) which extend outside the envelope are enclosed in solid insulation having an external earthed conducting layer which does not extend into the envelope. The component may be arranged in the innermost of a plurality of envelopes each containing a gas and arranged one within another, the gas nearest to the component having the greatest dielectric strength. The walls of the envelope or envelopes may follow an approximately equipotential surface. The envelopes may be of material such as synthetic resin, polythene, terylene, nylon, &c. strengthened with textile or glass silk gauze or tapes and each may have a lining of plastics foil. They may have relief valves and parts of lower tearing strength and, may be surrounded at a distance by earthed wire mesh cages which may be embedded in transparent plastics material. Conductors extending through the envelope are provided with solid insulation of the kind described in Specification 886,290 which has, outside the envelope, an earthed external conducting layer attached to the wire mesh cage. Inside the envelopes irregular or sharp metal members or those carried on supports may be enclosed in solid insulation. The gas used may be air under pressure N 2 , CO 2 , SF 6 , a carbon fluoride such as C 4 F 8 , a gaseous chlorine compound, neon, argon or mixtures. The gas pressure may decrease from the inner envelope to the other envelope. The gas may be circulated so that it can be purified and dried and its temperature or pressure can be controlled. The chamber in which the apparatus is housed may be filled with filtered air or with a gas or gas mixture having a higher dielectric strength. Fig. 1 shows one phase of a high voltage switch gear installation in which insulating envelopes 20-27 enclose the isolators 3, 4 and circuit breaker 7, 8. Admission and outlet pipes 27, 28 are provided for the gas as well as a valve 29 for exhausting the gas from the circuit breaker. Envelope 22 is separated from envelope 25 by a substantially gas-tight plug 30 of elastic foamed plastic. Fig. 3 shows an isolator having a contact pin 56 operated by an insulated shaft 61 by a servomotor 62. The gas is enclosed in a transparent plastic envelope 63 surrounded by a wire mesh screen 64 connected to the external conducting layers on insulation 59, 60 of the H.T. bus-bars 57, 58. A bulge 65 in the plastic envelope encloses an earthed electrode 66 which prevents flashover between poles 54, 55. An installation connecting two three-phase systems is also described (Figs. 2a and 2b, not shown).

Filed: 1960-03-18
Abstract: 922,594. Ice-cream freezers; refrigerating. CHERRY - BURRELL CORPORATION. March 18, 1960 [Sept. 16, 1959], No. 9634/60. Class 29. In a continuous freezer having a freezing tube 17 cooled by an evaporator 16 and containing a motor-driven dasher 63, hot-gas is supplied to the evaporator, e.g. when the flow of mix is interrupted so that the contents of tube 17 do not overfreeze. When the evaporator pressure has risen sufficiently, the supply of hot gas is interrupted. As shown, compressor 10 supplies refrigerant through condenser 12, receiver 13, filter 18, expansion valve 24 to the evaporator 16. Unevaporated liquid refrigerant from the evaporator collects in accumulator 14 which also receives liquid refrigerant from the condenser through pipe 36 and float valve 34. Liquid refrigerant is recirculated from accumulator 14 to the evaporator by an ejector 30 the working fluid of which is the liquid refrigerant flowing from the expansion valve to the evaporator. A constant evaporator pressure is maintained by a regulator 44 in suction pipe 42, the regulator being actuated by fluid bled through adjustable pilot valve 46 and pipe 48 from the suction pipe upstream of the regulator. Mix is fed to the freezing tube by a pump 58. When the power supply to the motors of pump 58 and the dasher is interrupted, or when these motors become overheated due to excessive freezing, a liquid refrigerant solenoid-operated valve 26 is closed and a valve 66 is opened to supply hot gas from the compressor outlet to the evaporator through pipe 64. If this is due to overheating of the motors, the supply to the motors is also interrupted. Simultaneously, a valve 68 in pipe 48 is closed which causes regulator 44 to be controlled at a much higher pressure by device 70. Also device 71 connected to pipe 48 upstream of valve 68 acts after sufficient supply of hot gas to close valve 66 and open valves 26, 68 to restore the system to normal. The dasher motor can be run while the feed pump motor is stopped. U.S.A. Specification 2,944,487 is referred to.
