Title: Heat conducting and electrically insulating binder - comprising e.g. metal oxide particles in adhesive matrix e.g. silicone used for heat transfer
IPC: H01L23/367
Filed: 1980-04-15
Abstract: A heat conducting and electrically insulating binder comprises a matrix of adhesive material in which are embedded heat conducting particles. The particles are pref. metal oxides (esp. Al2O3 and Be oxide), boron nitride or mica, which are electrical insulators while having good heat conductivity. The binder pref. also contains metal particles which are electrically insulated from each other. The binder is used for transferring heat from a heat source, e.g. an electronic component, to a heat radiator or to the surrounding air. The binder does not creep so that risks of short circuit are avoided.

Title: Copying machine using optical fibres - uses row of ends of fibre having different length at image side from original side to permit change scale
Inventor: KRAUSS OTTO
IPC: G03G15/041
Filed: 1980-11-12
Abstract: The optical fibres (1) are juxtaposed in such a way that their extremities (5,6) form one or more rows at each end (3,7) of the bundle of fibres. The length of the row at one end (3) can be different from the length at the other end (7) so that the image (4) can be reproduced at a different scale to the original (2). The change of length between both rows can be obtained by a change of space between the ends of the fibres or by a change of diameter between both extremities of the fibres. The array of fibres forming the scanner is integrated into a support comprising a flexible band.

Title: Dosing valve for adding molten lead to moulds - for making connections to the plates of lead accumulators
Inventor: LECOULS JEAN-LUC
IPC: B22D25/04
Filed: 1980-12-09
Abstract: The appts. consists of a chamber with a bottom inlet for pressurised molten lead. In the chamber is a vertical hole with a screw thread receiving a bolt. The bolt has an axial hole, which can be opened or closed by a ball located in the head of the bolt.

Title: Automobile courtesy light switch operated by opening door - has deformable cap enclosing spring contacts and sealing device acting against corrosion by ingress of liquid
Inventor: NIGON MICHEL
IPC: H01H13/18
Filed: 1980-12-23
Abstract: Electrical contact is made in the switch in the absence of pressure on a deformable cap (5). The circuit is connected to metal prongs (4) which have gaps (14) in them. The prongs are embedded in an insulating grommet (15) which lightly fits the hole in the vehicle body work (7). The deformable cap (5) envelopes a circular or square shaped sheet of springy metal (3) fixed to the grommet. The sheet has a cup shaped section fixed to its underside and is convex upwards. The cup bridges the contact prongs when the cap is free. When the cap is compressed by the closing of a door in its joints, the metal plate is flattened and the spring contact cup (13) is forced downwards into the gap in the prong faces - breaking the circuit. The insulating cap (5) fits between the body work and the grommet flange thus preventing air or liquids from entering the switch and causing corrosion.

Title: Dual function hydraulic pedal control for excavator - uses diesel compression pump and pedals which operate different valves in accordance with degree of travel
Inventor: BOURGES BERNARD MICHEL
IPC: G05G9/08
Filed: 1981-01-23
Abstract: The excavator has a hydraulic motor (2) which is mechanically coupled (5) to the rim (6) of a wheel on the vehicle. The motor is coupled to a fluid distributor (11) with a pedal (12) which controls position. The distributor is supplied by a hydraulic pump (9) driven (10) by a diesel engine (8). A pedal (31) on the vehicle is provided with three angular positions (31,31a,31b) providing angular travel to operate on the control shaft (33) of an electric relay (15) to operate an electrovalve (14) for a selective coupling circuit (13). Further angular travel operates a control (34) on a second relay (29) in the wheel braking circuit. The dual purpose controls are intended to reduce operator fatigue.
Patent FR-2475904-A1 (FR)
Inventor: TERRELL MARK
IPC: B63C11/18
Filed: 1981-02-13
Abstract: The invention relates to a breathing apparatus with a semi-closed circulation for divers. This breathing apparatus has devices for reducing the quantity of breathable gas fed to the breathing cycle, which devices respond to the external pressure to which the diver is exposed. In the case of increasing diving depth and the thus increasing pressure, the quantity of breathable gas flowing into the breathing cycle of the apparatus can be reduced by these devices, the partial pressure of the oxygen in the breathing cycle being maintainable between given pressure limits in the case of maximum or minimum consumption of oxygen. The breathing apparatus has gas passage apertures which are dimensioned such that they cannot be blocked by particles of dust or ice. The gas passage to the breathing apparatus can also be reduced in the case of continuing operating pressure, the gas exerting this operating pressure constantly flowing out into the breathing cycle and the devices for reducing the quantity of breathable gas opening when the operating pressure drops. As a result, the breathing apparatus remains operationally safe.

Title: Channel section piling assembly guide - has positioning and locking faces for fixed channel and rollers guiding moving channel
IPC: E02D13/04
Filed: 1981-04-07
Abstract: The guide for forming piling for harbours is used to interlock the flanges (B1,B2) of the channels which form the structure. It has a base plate with two parallel angles mounted back to back at one end. This forms a gap (4) to receive the bottom of a channel. A second channel facing in the opposite direction, is then guided by rollers (10,19,20,23) so that it can be lowered from a disengaged position to an interlocked position. The length of one channel enables it to fit inside the first channel, and pins (7) are inserted through holes in the two angles and the channel between them to secure the bottom of the channel. The rollers are in pairs at right angles to match the shape of the flanges on the sides of the channels. One (10) of the rollers at the joint region is oscillated about an axis parallel to its axis to assist connection.

Title: Multichannel transmission assembly for pyrotechnic firing signal - uses shock generator to detonate explosive to force metal strips against multiple output relay elements
Inventor: DURAND JACQUES PHILIPPE
IPC: F42B3/10
Filed: 1982-01-13
Abstract: A donor component (2) comprising a shock generates triggers the detonation of an explosive strip (12). This explosive is sandwiched between metallic plates (10) in which strips (30) are presheared to release the energy towards out put relay assemblies (4) mounted in the walls of the metal housing.The explosive is confined laterally by a U shaped steel strip (36). The housing is formed to contain the effects of the detonation and to minimise the effects of lateral detents on the presheared strips in the central cavity (20). This cavity has inclined side walls in which the output relays are mounted while the donor component is mounted in the base. This shape ensures that each output relay is triggered at approx. the same instant.

Title: Turbomachine wheel longest blade-wheel-guard play measurement - by dynamic method using one fixed and one moving proximity sensor
Inventor: DELON PATRICE
IPC: G01B7/14
Filed: 1982-02-12
Abstract: The device measures dynamically the play between the end of the longest blade of the wheel (1) of a turbomachine and the interior surface of the wheel guard (3) which surrounds the wheel. It has a first proximity sensor (4) of capacitive type which is fixed on the wheel guard to the right of the wheel and delivers a series of signals to its associated electronic appts. (5) which are images of the distances (d) which separate each of the blades (2) from the wheel guard at that point. A second proximity sensor is fixed to the end of one of the blades (of rank n for example). It consists of a conducting surface (6) electrically connected to its electronic equipment (7) which is situated near the rotor axis. This delivers a signal which is an image of the distance D(t) which separates the blade of rank n from different points on the wheelguard. A calculating device (8) receives signals representing the distances d, and by radioelectric transmission the signal representing the distance D(t). It calculates the difference delta between signals from the first sensor representing the blade carrying the second sensor dn and the longest blade dmin (delta=dn-dmin) for each turn of the rotor. It subtracts this difference signal from the signal from the second sensor (D(t)-deltad) to produce a signal representing the distance separating the end of the longest blade from each of the points of the wheelguard.
