Title: Printed circuit for vehicle lighting fault detection - uses low resistivity tracks on ceramic substrate as control resistances in series with respective lamps
Inventor: GOMEZ MICHEL
IPC: H05K1/09
Filed: 1979-12-19
Abstract: The circuit has a respective low value control resistor (3) mounted in series with each of the vehicle lamps or with each lamp pair (1,2). The voltage across each control resistor (3) is monitored to detect lamp failure. Each control resistor (3) is formed as a conductive track of Ag or a similar metal deposited on a ceramic substrate. An extension of each track may be covered with tin and act as an output connection. A dielectric layer may be deposited before the tin layer to define precisely the zones where the tin is to be deposited. Pref. the control resistor (3) is connected to one input of a comparator (5) also receiving a given reference value. The output of the comparator changes from a binary value of '1' to a value of '0', to indicate lamp failure, and is fed to a memory comparator (6) controlling a failure signal light (7).

Title: Slow speed thermo-mechanical motor - has thermal cylinder connected to double force crank drive and spring or weight to extract energy
Inventor: GIRAUD FRANCOIS
IPC: F02G1/02
Filed: 1980-03-14
Abstract: The motor for converting heat into energy by the change in volume inside a chamber, is subjected to two forces. The first is obtained from a weight (3) suspended on a cable (1) and wound onto a drum (2). The drum is coaxial with a smaller diameter part onto which is wound a second cable (4) connected to a piston. Between the second cable and piston are double linkages each with rollers at the ends of their arms, connecting them and travelling along guide surfaces. The shapes of these surfaces give a variable force on the connecting cable. An alternative method of applying the first force uses a swinging arm controlled by a spring and connected to a second arm attached at the other end to a sliding piston.

Title: Membrane vacuum pump providing oil free primary vacuum - uses membrane fixed over plate and electromagnetically operated plate to alternately compress opposite sides of membrane
IPC: H02K33/12
Filed: 1980-03-17
Abstract: The oscillating membrane vacuum pump is used to generate primary vacuum for high vacuum pumps which require a primary vacuum before they can operate. The vacuum produced by the membrane pump is free from oil mist pollution. The device includes a neoprene membrane which is laid over a stainless steel plate. The membrane is drawn tight over the edges of the plate and has holes round its periphery to allow air to exhaust to atmosphere. The inlet air is drawn through a hole in the centre of the stainless steel plate when the membrane is raised above the surface of the plate. Electromagnets attract alternately the ends of a flexible steel plate which flattens one half of the membrane against the plate then progressively draws the other half down forcing air out the exhaust holes.

Title: Pivotable transfer arm with rotary pick-up and magnetic clutch - oscillates rectifying post for incremental rotation of workpiece
Inventor: DUVERNAY ROGER
IPC: B24B41/06
Filed: 1980-04-04
Abstract: The rectifier may be used to align parts (1) for homokinetic joints, i.e. sleeves with a biconical barrel (1b) and three radial stub axles (1a). The machine treats axles (1a), using a pivoting transfer arm (12) with a magnetic (17) pick-up (11) to move a piece (1) from a loading-station (C) to the grinding-station (A). The pick-up now releases the piece and lever-hooks (9) secure it on a plate (5) during the grinding of a primary axle (1a), its arm (12) having retracted. The arm (12) now pivots back to re-engage the piece which is released simultaneously by hooks (9), and a rack and pinion gear train (15) is used to rotate the piece until a second axle (1a) is presented to grinder (3). The piece (1) is again locked on the plate, the arm (12) retracts, and the cycle repeats.

Title: Cooling of ingot moulds - where external surfaces of mould are provided with prongs or ribs exposed to ascending streams of cooling air
Inventor: GARCIN PIERRE MARIE GEORGES
IPC: B22D7/06
Filed: 1980-05-08
Abstract: The external surfaces of the walls of the mould are provided with numerous cooling prongs or ribs, which are monolithic with the walls and increase their surface area. The distribution of the prongs or ribs promotes the circulation of cooling air along the outer surfaces of the mould. Pointed prongs or tapered ribs are pref. employed to improve the transfer of heat from the mould walls to the cooling air. The pref. moulds are provided with cast or machined prongs, ribs or fins; and nozzle pipes are used to blow streams of air upwards along the outer surfaces of the mould. The nozzle pipes are pref. connected by valves to a source of compressed air. The time required for cooling an ingot cast in the mould is reduced; thermal stresses in the mould walls are diminished, so mould life is increased; the surface finish of the cast ingot is improved; and the thickness of the mould walls can be reduced, so mould costs are decreased.

Title: Adjustable light alloy suspension arm - has arm adjustments via torsion bar and internal friction damping
IPC: B60G11/44
Filed: 1980-05-30
Abstract: The arm is used for the suspension of materials and vehicles. It works in steps to give a cycle composed of torsion and flexure. It is made of material of appropriate elasticity with internal friction to damp vibrations. The damping is given by embedding a lever balancing the other components. A suspension arm is used, with limited vertical displacement obtained by a stop (7). The material used is aluminium alloy. A torsion bar (1) is chassis fixed and the arm (2) is embedded in a shoe (3). The lever arm (5) adjusts the arms.
Patent FR-2458614-A1 (FR)
Title: Raschel machine with non-swinging guide bands - having additional comb to orient warp ends for correct lapping-comb engagement
Inventor: KOHL KARL
IPC: D04B27/10
Filed: 1980-06-11
Abstract: A Raschel machine having yarn guide-bands which move only parallel to the needle bar, working in conjunction with a separate lapping comb, has an additional guide comb mounted behind the needles which executes a rising, sinking and swinging movement between the lower edge of the guide-bands and the upper edge of the trick plate. The comb enters the warp just beneath the guide bands after they have made their underlap shogs, and moves vertically downwards to draw the warp ends into a more nearly vertical posn., to enable the lapping comb to make a correct entry. The rear comb maintains a vertical run of the yarns beneath the guide-bands irrespective of the length of shog, ensuring the lapping comb correctly engages the yarns. Patterns are, therefore, no longer restricted to short underlaps, which represents a large increase in design capability.

Filed: 1980-06-18
Abstract: The ski boot (1) is of plastics and has a rigid lower shell (2) connected to an upper (3) whose lower edge interacts with the top of the lower part through at least one flexible strip (9). This is mounted transversely to the longiutidnal axis of the boot approximately on at least one part of the perimeter of the foot in an area extending from the fold to the instep with the strip spaced from the edge on the other side to form a transverse opening. This opening (8) is interrupted at at least one point in its longitudinal direction by a support adjustment lug (10) which ensures the direct contact of the lower edge of the upper with the strip as the leg moves.
