Title: Improved device for the oscillographic indication or recording of electric or mechanical variations
IPC: G01L23/26
Filed: 1938-05-21
Abstract: 515,027. Cathode ray oscillographs. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN. May 21, 1938, No. 15220. Convention date, May 24, 1937. [Class 37] [Also in Group XXXVIII] In oscillograph apparatus employing a bridge network for indicating or recording electrical or mechanical variations, the impedance that is subjected to the variations to be observed and which modulates the high-frequency generator is not spatially separated from the remainder of the bridge which is constituted as a unit located at the point where the variations occur and is connected by supply conductors to the generator and oscillograph. A bridge network is provided for each of the two coordinates, a common high-frequency source being modulated by each bridge impedance. The oscillatory circuit 8, 9 of generator 1 is coupled to coils 17, 18 feeding transformers 19, 21 connecting the two measuring bridges 2, 3. Condenser 25 is varied by the quantity under observation, for example, engine pressure, while condenser 34 can be varied from the engine shaft, an indicator diagram being then produced on the oscillograph 6 which is connected to the bridge outputs through sheathed conductors 28, 37. The impedance bridge 23 ...26 may comprise a pressure-cartridge, Fig. 2, the diaphragm 56 forming one plate of condenser 25, the other bridge members being contained within the housing 54, the leads 41, 42 and 28 to the generator and oscillograph being located in a flexible metal tube 51. The capacitances of the leads 41 ... 44 between the generator and bridge are arranged to produce in the leads an oscillatory condition tuned to the generator and, if separate impedances are included, they are of small value in relation to the self-capacitance. The invention is stated to be applicable to observing vibrations of buildings.

Patent GB-419962-A (GB)
Title: An improved safety or cut-out device for electric kettles or other electrically-heated vessels or containers, and other electrical apparatus
IPC: A47J27/21
Filed: 1933-05-27
Abstract: 419,962. Automatic circuit-breakers. EVESON, J. C., White Lodge, Pedmore, Stourbridge, Worcestershire. May 27, 1933, No. 15346. [Class 38 (v).] A safety cut for an electrical-heated appliance comprises a switch rod 7 having a contact bridge 9 for engaging fixed contacts 25. The rod 7 is biassed towards the off position by a spring 10 and is held closed by the engagement of the hooked end 12 of a spring blade 11 with the bent round end 2<a> of a pin 2 normally held by fusible metal to a cap 4. On overheating, the switch opens due to spring 10 which causes the arm 2<a> to turn and release the blade 11. A weak spring 13 returns the arm 2<a> to its original position before the solder solidifies. The hook 12 can then be re-engaged owing to the resiliency of the blade 11. In a modification, the control arm 2<a> is formed on a cup which is rotatable on a fixed pin. In another modification, the rod 7 does not carry contacts, but on overheating moves to force the supply socket off its pins to disconnect the supply. In a further modification shown in Fig. 6, the rod 7 is prevented from moving to push the socket 17 off the pins 18, by the engagement of a projection 12 with the end 22<a> of a spring 22 fastened to a pin 2 normally soldered to a socket 24. When the solder melts, the pin 2 rotates and the rod 7 is released to disconnect the supply. The pin 2 is moved back to its original position by a weak spring 23 before the solder solidifies. On pushing the rod 7 in, the projection 12 is pushed past the catch 22a due to the resiliency of the spring 22.

Abstract: 1,147,613. Moulding expanded polyolefin. HERCULES Inc. 13 April, 1966 [15 April, 1965], No. 16175/66. Heading B5A. [Also in Division C3] Finished, moulded articles of cellular polyolefins are produced by heating a mixture of polyolefin, an azido cross-linking agent, and a blowing agent in a closed mould to a temperature above the softening point of the mixture and sufficient to release the gas from the blowing agent and to effect azido modification of the polyolefin, while maintaining sufficient pressure to prevent expansion of the mixture during the heating period, then reducing the pressure to allow expansion within the confines of the mould, and cooling to prevent further expansion when the mould is opened. Articles such as battery boxes, cartons for soft drinks, milk and beer, ice cream containers and automobile sun visors can be produced, and the examples describe the preparation of boxes from polypropylene foam, polyethylene foam, and ethylenepropylene copolymer rubbers, and of an automobile sun visor from polypropylene. An apparatus for making a partitioned box is described. The mixture 1 of polyolefin, azido cross-linking agent and blowing agent is placed in the bottom of the mould 2 which may be preheated. The part 3 of the mould is placed in position with a gasket 4 to prevent loss of gas and is held in position with a clamp 5. The assembly is placed in a platen press 6 and heated. Gas 7 is released and is compressed as the mixture expands. At the end of the heating cycle the pressure is released and the mass expands to fill the mould. Modifications of the apparatus include the provision of holes through the mould part 3 for release of the pressure, and which are sealed by a silicone rubber gasket during compression of the gas, or manifold means on the upper mould part 3 for the admission of further gas to augment the pressure of the gases 7 whereby lower foam densities and a smaller cell structure is obtained.
