Title: Device for positioning the reed on loom used for weaving tapes - includes rotary eccentric cams acting on a linkage
IPC: D03D49/60
Filed: 1976-01-19
Abstract: The need of a loom is raised and lowered by a linkage including an L-shaped lever of which one yarn is connected to a vertical rod attached to the reed and of which the other arm is connected to a horizontal rod pivotally attached to a drive lever pivotal at its lower end. A centrally pivoted control leverl is mounted on the drive lever and a pair of slide bards are attached to opposite ends of the control lever. Each slide bar carriers a follower roll which runs in a guide and acts on an associated circular eccentric cam. At least one cam is rotated by a drive shaft via a clutch operated by a Jacquard mechanism. The cam is reciprocated rotationally through 180 degrees. The mechanism is simple and allows rapid and precise positioning of the reed.

Patent FR-2379076-A1 (FR)
Title: Detecting and measuring seismic shocks etc. - by comparing signals from one part of laser beam, reflected from transducer, with reference signals from other part
IPC: G01H9/00
Filed: 1976-06-09
Abstract: Appts. for detecting and analysing seismic shocks incorporates a detector and an optical system. The coherent luminous beam from a laser generator is sepd. by a semi-transparent mirror into two parts. One feeds a reference chain in which is a laser beam modulator and which is used to simulate the shock being analysed. The other feeds a measuring chain where the laser beam oscillates between an optical system and the detector. The chains include interferometric and visualisation elements detecting the signals transmitted. The information so obtained is processed by a comparator and a computer to provide an analysis of the shocks. The detector is e.g. a transducer with a silvered surface which receives and reflects the laser radiation of the measuring chain. The invention can be used for detecting and analysing all subterranean and submarine disturbances such as earthquakes, the presence of petroleum pockets and nuclear explosions. It occupies less space and is less complex and more reliable than existing appts. It can be made portable and the transducer can be orientated in all directions and remotely controlled, e.g. when it is buried.

Patent FR-2372096-A1 (FR)
Title: Bottle top capsules having extruded cellular plastic walls - to obtain a smooth surface after stretch fitting without heating
IPC: B65D41/62
Filed: 1976-11-29
Abstract: A bottle top capsule is made from extruded plastic tubing or sheet having a cellular structure which can be stretched to fit the capsule over a slightly larger bottle top. Unlike thin, heat shrunk film capsules, the thick deformable walls accommodate any imperfections or trapped air or moisture at the bottle surface withotu disturbing the smooth external appearance of the capsule. Also the bottle does not have to be exposed to heat during fitting of the capsule. If fabricated from sheet, the cylindrical capsule is closed by a lap joint welded under sufficient compression to reduce the thickness of the joint to that of the adjacent walls.

Title: Solar collector incorporating heat exchanger and transparent cover - made by encasing components in foam plastic in mould
IPC: F24J2/04
Filed: 1977-03-15
Abstract: The solar collector consists of a heat exchanger, covered by a transparent material. Such exchangers are made of metal or plastic materials conditioned to have a strong absorption in the infra-red or visible regions of the spectrum. For this, varnish or soot may be applied as a layer, or a material can be mixed in. The transparent layer should prevent cooling of the collector by convection. It consists of a plate of glass or plastic material with a high transmission coefft. for wave-lengths 3 mu m and strong reflection for wave-lengths >3 mu m. The transparent material, the heat exchanger and distance pieces are inserted in a compact body formed of plastic foam. The collector is made by placing the transparent material, the exchanger, the distance pieces and a frame in a mould, closing the mould and filling it with foam. Cf. existing collectors, the collector is very efficient, is light and can be made easily and at low costs.

Title: Central heating installation for building - uses low temperature water for underfloor heating and to heat ambient air circulated by fan
IPC: F24D9/00
Filed: 1977-05-27
Abstract: The installation centrally heats a building and uses a combination of underfloor heating and fan assisted air for the ambient surroundings. The water is heated to a low temperature of 30-60 deg.c and passes (1) into a storage tank (BT). It then traverses the underfloor piping (2, 6) and emerges into units (BP, B'S') for heating air blown over them (F). The water then returns (7) to source. The air picks up additional heat from being passed over another heater unit (BS) and the storage tank. The temperature is controlled by a thermostat (5) and valve (4) controlling a storage tank bypass.

Title: Welding heat resistant alloy rings onto poppet valves - via automatic machine, where valves are for use in IC engines
Inventor: MOZZHUKHIN A A
IPC: B23K31/02
Filed: 1977-07-19
Abstract: Plant for deposition welding is esp. for welding a ring (a) made of heat resistant alloy onto the working surface of a poppet valve (b) intended for an IC engine. A row of the valves with stem pointing downwards flows down an inclined chute; and a row of rings (a) flows down a second chute. A manipulator successively removes one valve (b) and one ring (a) from the two chutes. The manipulator turns each valve so the stem of the latter points upwards, and moves the ring against the valve. A swivel plate fitted with a loader, spray quenching nozzle, and discharge pipe for the welded assembly (a, b) is used in conjunction with the manipulator and swivels between three positions. The loader lifts the valve stem up through a ring induction heating coil so the setm enters a chuck which rotates during welding. After welding, the quenching nozzles is used and the assembly (a, b) is then released from the chuck so it enters the discharge pipe. Used for high speed mass prodn. of valves for IC engines.
