Title: Dielectric liquid cooled transformer - uses dielectric liquid sprayed over coils where it vapourises and flows through grooves in coil to allow penetration
Inventor: GIBBS RICHARD DALE
IPC: H01F27/18
Filed: 1981-05-27
Abstract: The three-phase transformer consists of a housing containing three coils (14), one per phase. Each coil is on a respective magnetic core (22) and is immersed in a volatile dielectric coolant (16) such as C2Cl4 or C8F10O. The coil conductors are square or rectangular cross section with the coils formed by stacked windings each of two or more contiguous radial spirals. The dielectric is vaporisable during the normal operating temperature range and sprayed onto the coils by a pump (18), so that cooling is effected by vaporisation of the coolant. One or more faces of the coil spirals are formed with grooves, typically 0.152mm deep by 6.35mm to allow penetration of the coolant. The grooves are formed before the spirals are coated with an insulation by passing the wire conductor through a device for forming the grooves at preset intervals.

Patent FR-2521769-A1 (FR)
Inventor: EYNARD HENRI DENIS
IPC: H01H35/24
Filed: 1982-02-18
Abstract: The closing switch according to the invention has: an element (80) which upon an increase in temperature of the liquid to be monitored exhibits a bellying effect; a plunger (50) bearing against the bellying element, this plunger being loaded in the direction of the deformation produced by the bellying by a calibrated spring (40), and in the other direction by a diaphragm (60) which can be elastically deformed under the action of the pressure exerted by the liquid. In this way, an increase in pressure produces a displacement of the plunger in the sense of reducing the power exerted by it on the bellying element, the bellying temperature being increased. In this way, the permissible temperature increases, before the contact of the switch closes, as a function of the pressure prevailing in the circuit.

Title: Intruder alarm less prone to false alarms - activated IR emissions and ultrasonic reflection pref. includes polymer etc. components
Inventor: MICHERON FRANCOIS
IPC: G08B13/193
Filed: 1982-05-25
Abstract: An intruder alarm consists of a detector contg. polarised material with both piezoelectric and pyroelectric properties for sewing acoustic vibrations and electromagnetic waves in the infra-red range. A significant variation of either of these emissions in the area surveyed by the detector causes an electric signal in at least one separate circuit. Signals occurring simultaneously in circuits corresponding to acoustic and i.r. waves trigger an alarm. The material used in the detector is pref. an inorganic oxide, esp. BaTiO3 or LiNbO3 type structures, e.g. titanium lead zirconate ceramics or LiTaO3 or a vinylidene fluoride (co)-polymer. These materials are treated in an intense electric field to acquire piezoelectric and pyroelectric properties.
