Inventor: LAFLAQUIERE REGIS
IPC: D01H9/14
Filed: 1981-01-29
Abstract: Process and device for cutting the thread in the automatic draw-off of a bobbin in a spindle-type textile machine. According to the process, after the standstill of the spindle (1) for drawing off the full bobbin (5') and after a partial draw-off of the bobbin raised by the gripping member (13) of the automatic lifting device, the spindle (1) is temporarily set in rotation again, in order to rotate a thread-cutting ring (12) which is connected firmly to the spindle and which cuts the thread (10). This process makes it possible to improve the safety of the thread-cutting operation on a full bobbin and to prevent a partial unwinding of the thread before the cut.

Patent FR-2496895-A1 (FR)
Title: Peak clipping voltage measurer for async. motor control - uses peak clipping circuit with fast filter to measure inverter output and to increase dynamic control
Inventor: SCHORNER JOCHEN
IPC: G01R31/34
Filed: 1981-12-17
Abstract: The output voltage from the three phase, DC link, variable frequency inverter is applied to the stator of an asynchronous motor. A three phase tapping carries the three phase voltage to the measurement circuits. The AC voltage is rectified by a bridge rectifier. This voltage contains large superimposed spikes arising from inverter commutation. A peak clipper reduces the amplitude of the spikes to about 5 per cent of the nominal output, and a two pole, short time constant filter removes the remaining ripple. A small compensating voltage provides an approximate average replacement for the lost peaks, giving an accurate measure of motor voltage with fast following of the motor voltage.

Title: Impact retracting plough beam - has frame which pivots back against spring via tie rod rocking lever and strap with resistance reducing progressively
IPC: A01B61/04
Filed: 1982-02-24
Abstract: The return spring pivotable beam (2) permits the tools (3,4) of a reversible plough to retract when a rock is encountered, providing progressively reducing resistance to retraction. The horizontal beam supports a symmetrical arrangement of two working units (2a,2b), being applied to a frame plate (5) by a spring (7) acting through a pin-jointed tie rod (8) and linkage. Half rounded end plate (6) cantilevers (6a,6b) house onto the axle pins (5a,5b) to form alternative fulcrums for the full circle pivoting of the beam during retraction. The leverage system comprises a rocking lever (10) and a strap (14), its geometry being such that the square offset of the tie rod (8) from the rocking lever fulcrum (12) increases as the beam pivots.

Title: Engine injection pump port closing detector - uses constant pressure gas supply connected to discharge union by control gate
Inventor: ORIEUX ANDRE
IPC: F02M65/00
Filed: 1982-03-09
Abstract: The circuit determines the start and/or the end of the period when ports connecting the interior of a housing with the exterior are shut off, for a Diesel engine fuel injection pump. The housing (28) contains feed (4a) and discharge (5a) ports and a movable component (10) freeing or shutting them, so that it is alternately connected to a liquid-supply tank and cut off from an injector etc., and vice-versa. To effect the determination referred to, the connections from the housing to the tank and injector are uncoupled, that to the injector being replaced by one (20,19) to a source of compressed gas at constant pressure (24). The component is moved inside the housing while observing the pressure in the latter.

Title: Cylindrical sheath for pyrometric rod and its fabrication - using silico-calcareous material autoclaved and heat treated
IPC: G01K1/14
Filed: 1982-03-12
Abstract: The sheath (4) for a pyrometric rod for plunging in a bath of molten aluminium zinc, or one of their alloys, is made of a silico-calcareous material which contains a pliable mineral and which has been autoclaved and heat treated to a temperature of at least 500 degrees C. The sheath has an annular cylindrical transverse cross-section of external dia. of the order of 45 mm and internal dia. of the order of 21 mm. The pyroelectric rod has an armature formed from a metallic tube (2) around which the sheath fits and inside which the thermocouple is loged. A coupling section is screwed into a threaded extremity (2a) of the tube. The sheath is fabricated by rounding off the outside of an elongated back of silico-calcoreous material and drilling a hole of appropriate diameter inside it. The sheath is then treated in an autoclave and then progressively heated so that the temperature rises by about 50 degrees C. per hour as far as 550 degrees C. where it is maintained for an appropriate duration.

Abstract: The lock for a vehicle body panel comprises a latch (88) having an enlarged lower end (54) which locates beneath first (50) and second (74) support surfaces on a locking lever (24). The panel is opened by a remote release acting on one end (34) of the lever, which causes the lever to pivot against the action of a first spring (58), releasing the latch (88) from the first support surface (50). The other end (80) of the lever is then manually actuated from the vehicle exterior, against the action of another spring (78), which causes the second support surface (74) to release the latch, allowing the panel to be fully opened.

Title: Time delayed fault current trip for circuit breaker
Inventor: FRAMERY DANIEL
IPC: H02H3/33
Filed: 1982-07-26
Abstract: The circuit provides a time delay in operating the circuit breaker trip coil (6) such that the overall fault protection on a group of circuits can be staggered. It provides this delay using simple components and does not require any electronic manipulation or computation. The summing current transformer (10) has an additional winding (12) which is connected to a delay circuit (13). The latter comprises parallel connected capacitors (15,17), a diode (14), and discharge resistance (16). When a fault occurs a pulsating current, due to the diode, flows in the tertiary winding (12). As the capacitor (15) initially presents a very low impedance, the current flow in the secondary winding (11) connected to the trip coil is small, and there is no trip. As the capacitor charges the secondary voltage rises and, if the fault persists, the trip will operate. The time delay is determined by component values.

Patent FR-2511839-A1 (FR)
Inventor: AUDERSET REGIS
IPC: A01G3/00
Filed: 1982-08-31
Abstract: The body (16) of the secateurs (1) contains a cylinder which is fed with compressed air through a connection piece (33). The lever (37) controls the intake of compressed air to the cylinder (16), which causes the movement of the moving blade (21) against the backing blade (22). When the lever (37) is freed, a spring causes the secateurs to open and pushes the air from the cylinder through the hose (36) and through one of the orifices of the nozzle (46). The biocide liquid (15) contained in the bottle (4) of the supply device (3) is sucked through the hose (5). The jet of mixture is divided by the triangular stop (49) into two parts, one of which is sprayed onto the blades, whilst the other goes to the trimming cut in the cut branch.
