Title: Carbon fibre reinforcing fabric - with carbon fibres gimped with synthetic or natural fibres
IPC: D03D15/00
Filed: 1971-05-19
Abstract: The fabric is pref. woven and has pref. 8 wefts/cm. of carbon fibre yarns (e.g. PAN based carbon filament tow) which are gimped by natural or synthetic yarns (polyhexamethylene adipamide) pref. at a twist level of 300 turns/m.

Title: Veneer conveyor system - incorporating stacking installation and working with variable drive motor
IPC: B65H31/30
Filed: 1974-03-28
Abstract: Veneer conveying and stacking installation for veneers coming from a web dryer. There are conveyor hands and counter bands which press the veneers coming from the web dryer against the bands with an installation to count the veneers and a stop located behind the bands in the direction of conveyor movement which causes the stacks to be stacked above each other. There is also a support system which carries a pre-determined number of veneers formed into a stack and permits it to fall when complete on to a band located below which in turn conveys it to a collecting point. The bands and counter bands aremoved by a suitable drive system at a speed of 120m/min as against the speed of 30m/min for the veneers with the motor speed adjustable in accordance with the thickness and specific weight of the veneers.

Title: Static power inverter - synchronous capacitor or LC circuit produces high frequency input control emf.
IPC: H02M5/27
Filed: 1974-04-02
Abstract: The circuit has a primary inverter in which a power flow circulates between the outpout and input circuits. A second circuit operates the same way. The two input circuits being connected in parallel to an input supply being used to obtain the required output. The input supply uses a synchronous capacitor and has a frequency very much higher than that of the output of the two inverters. This arrangement removes much of the complexity and expense normally incurred due to the inherent harmonic content and parasitic oscillation requiring sophisticated filtering and also the need for large phase correction capacitors.

Title: Liquid refrigeration process - pumps with high speed and turbulence over tubes in which coolant circulates
IPC: F28D7/10
Filed: 1974-06-20
Abstract: A refrigerating medium at a temperature appreciably below the freezing point of the liquid to be treated, is circulated through a central tube. The liquid is circulated at high speed (1 - 3m/s) and turbulence (8-24000 rpm) round the tube, so that no crystals are formed adhering to the latter. The liquid can be pumped through annular passages surrounding the tubes, which can be of polished metal, stainless steel or copper. They can be externally clad with plastic skin of a few microns thickness, so as not to have any appreciable effect on the thermal conductivity of the copper.

Patent FR-2304104-A1 (FR)
Title: High resolution photolithographic masters - using ionic bombardment colouring of masked prepared glass
IPC: G03F1/54
Filed: 1975-03-11
Abstract: The high resolution mask for the photolithographic process is made by diffusing ions of a colouring metal into the surface layer of a glass. The surface of the glass is then covered with a protective mask pattern, which can be a photo resist layer. The metal ions are then coloured by a process involving a heavy water chemical which activates the ions. The plate is then subjected to heavy ionic bombardment in an atmosphere of an inert gas and oxygen, to reduce the ions. The colouring process is then completed while at the same time the ion bombardment sputters away the protective pattern. A hard wearing, high resolution pattern is then left impregnated in the glass plate.

Title: Multipin electrical connector - has pins removable by insertion of cylindrical tool in front face of connector board
Inventor: DEBAIGT JEAN
IPC: H01R13/424

Title: Lubrication of high speed rolling bearings - with oil sprayed on balls by nozzle and knife edge seals to retain oil in housing
IPC: F16C33/66
Filed: 1976-03-30
Abstract: The lubrication system is for high speed rolling bearings used on electric motors. The shaft (1) is provided with a ball bearing (2) and oil is directed by a nozzle (4) onto the inner race (5). Some of the oil flows from the chamber (3) into the chamber (11). The rest of the oil flows through the bearing into the chamber (16). The oil from the chambers (11, 16) flows into the passage (20) where it is returned to the pump. The leakage of oil along the sleeves (8, 9) is prevented by the knife edge seals (13, 19). The spaces (12, 18) between consecutive seals is vented to atmosphere so that there is no pressure to force the oil past the seals.
