Title: Proximity detectors
IPC: G08B13/26
Filed: 1971-04-19
Abstract: 1322279 Proximity detectors PYROTECTOR Inc 19 April 1971 [11 March 1970] 22427/71 Heading G1N A proximity detector includes a voltage sensor 1 to which pulses from pulse generator 5 are applied via a gating device, transistor 4, to the control electrode of which is connected a probe 6 for connection to an object to be protected or monitored whereby a change in capacitance 8 of the object causes a change in applied voltage at the control electrode to effect a change in the magnitude of the pulses. In the absence of a body proximate to the body being protected capacitor 3 is charged by the pulses from the generator 5 passing through the collector emitter path of transistor 4, the voltage at the base of which is maintained at such level between pulses from the generator 5 that the voltage across capacitor 3 is high enough not to trigger the voltage sensor 1. When capacitance 8 is increased due to the presence of a body near the object the bias current is diverted from the base of transistor 4 and the amplitude of the current pulses from the generator are decreased so that the voltage across capacitor 3 drops and the voltage sensor 1 triggered to operate an alarm. Transistor 4 may be replaced by a cathode follower. The probe 6 may include a bifilar lead, Fig.3 (not shown), providing a single conductive path from the base current source to the transistor so that fracture of the probe leads disconnects the supply and actuates the trigger circuit.

Title: Improvements in or relating to shoe stiffeners
IPC: A43B23/08
Filed: 1950-09-13
Abstract: 696,225. Toe stiffeners for shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd., HILL, M. G., and WILKINS, R. J. Sept. 12, 1951 [Sept. 13, 1950], No. 22471/50. Class 17 (ii). Relates to stiffeners made as described in Specification 530,322 in press apparatus such as that described in Specification 487,159, by which a mass of impregnant dissolved in a volatile organic solvent is deposited between the faces of two superposed blanks of absorbent sheet material such as cotton swansdown cloth, and is spread and caused to penetrate into the blanks, which are then stored until required for use in air-tight containers, when they are removed and separated. Backing material prevents the impregnant from emerging on the opposite faces of the blanks. According to the invention, some of the original stiffness of the blank is lost on spreading and penetration of the impregnant, owing to the solvent action of the impregnant at least on part of the backing material. This latter may comprise two coatings, the first of which can be softened by the solvent for the impregnant while the second and outer coating is substantially impermeable to the impregnant. The first coating may be gum, natural or synthetic resin, a cellulose derivative, e.g. celluloid, or a rubber in an organic solvent or as an aqueous emulsion or suspension and the second coating may be china clay or film of starch.
