Patent ES-8302907-A1 (ES)
Title: Optical fiber temperature sensor.
IPC: G01K3/00
Filed: 1981-10-09
Abstract: This invention relates to a novel fiber optic temperature sensor based on internally or self-generated thermal radiation. The wavelengths of the spectral composition of the self-generated thermal radiation vary along the length of an optical fiber as a function of the variations in the temperature of an object along the length of the optical fiber. However, since the total radiation varies exponentially with temperature, the spectral composition and total power of the radiation transmitted to an end of the optical fiber is determined substantially by the highest temperature region along the optical fiber whereby the temperature, location and length of a hot spot, or region, of the object is determined.

Abstract: EP--48593 A The axial wave drive torque converter includes a rotatable input shaft (41) whose one end is journalled by a spigot bearing (43) in an output shaft (44). A swash plate (45) is rotatable with the input shaft and imparts an axial thrust to a male swashing member (47). A constant velocity universal joint is fixed to the internal dia. of the male swashing member, and has male (49) and female (50) grooves and balls (51). - A number of further balls (54) are recessed in a wavy circumferential groove (55) in the male swashing member and are also recessed in axial grooves (56) of a rotating female member (57) fixed to the output shaft (44). In use, the balls are forced to precess in the wavy groove (55) causing the female member to rotate and transmit this motion to the output shaft at a reduced speed and a multiplied torque relative to the input shaft. This reduction and multiplication is a function of the number of waves in the circumferential groove.  (4)

Title: Methods of hose manufacture, and hose thus produced.
IPC: B29C48/34
Filed: 1982-07-08
Abstract: A method of continuous hose manufacture in which hose comprising a liner 2, reinforcement 5 and cover 7 is cured by passage through a generally horizontal straight curing tube 8 containing a curing medium at a pressure and temperature sufficient to cure the hose. The curing medium acts directly on the outer surface of the hose and has a specific gravity substantially equal to that of the hose assembly passing through the tube 8 so that the latter is essentially supported by its buoyancy in the curing medium. The method enables hose to be produced in which curing is effected with the hose in a substantially straight configuration and subject to small, e.g. of the order of 10-100 Kg, haul-off tensions so that displacement of the reinforcement structure from its optimum configuration is minimised.

Filed: 1985-05-23
Abstract: To achieve improved and, in particular, optimum deflection correction of television picture tubes the sawtooth signal from the horizontal or vertical oscillator which is conventionally subjected to a correction, is left uncorrected.

Accordingly, the deflection correction is not carried out by influencing deflection means, but by a corresponding correction of the time relation of the video signals with respect to their loci on the picture screen.
