Patent FR-2487759-A1 (FR)
Inventor: HANCOU THEODORE
IPC: B60S1/38
Filed: 1980-09-09
Abstract: The hinge of a component (2) on a support (1) is obtained by virtue of two projections (3) integral with the support and each engaged between the narrowing points (11) of a groove (9) formed in the hinged component (2). A stub (8) is pressed by an elastic finger (7) of the support (1) into a click-in notch (12) of the hinged component (2). When the elastic finger (7) is slightly raised, the articulated component (2) may be dismantled, the projections (3) sliding in the grooves (9).

Abstract: Each stall is defined by a pair of parallel partitions formed of wood and coated with glass fibres in a resin matrix. Each partition is enclosed along its edges by U-section frame. The end of each stall is formed by a series of horizontal bars whose ends abut against the panel surround. Vertical bars are welded by the vertical rear edge of each panel and the ends of the transverse horizontal bars are welded to the vertical bars. The open ends of the stalls are closed by pivoting doors which are also made of vertical and horizontal bars.

Title: Fluid-pressure actuator for aerofoil section - has internally-vaned rotor rotated by pressurised fluid and then urged axially to deployed position
Inventor: BITHREY ALAN RICHARD
IPC: F42B10/20
Filed: 1980-09-16
Abstract: The rotary actuator (3) for e.g. a fin (2) of a guided weapon, has an axially-movable internally-vaned rotor (3r) and an externally-vaned stator (3s) with an annular flange (9). The rotor is turned about the stator axis (X-X) by the pressure of the fluid (which may be a liq. or a gas) supplied to chambers through ducts (18,19). Pressurised fluid in an annular chamber (20) adjacent the flange (9) holds the rotor in a left-hand position relative to the stator to both seal the chambers axially and release rotor locking devices.

Patent FR-2492942-A1 (FR)
Title: Anti-jamming device for push-button actuated valve - uses recoil spring to bring about closure irrespective of push-button status
Inventor: PATIENT LUCIEN
IPC: F16K21/10
Filed: 1980-10-24
Abstract: The device prevents the jamming of a valve which closes automatically after a definite time interval, the valve incorporating a push-button (15) which is depressed to lift an obturator off the valve seat (12). The obturator is rigidly connected to a casing (17) housing a displaceable piston (16). The piston communicates with the water feed through a calibrated hole (20). The piston is rigidly connected to the push button which transmits movement to the casing through the combined effects of friction and suction. The piston may be recoil sprung and may be connected to the button by a rod (14) which passes slidably through the obturator. If the button is held in the depressed position the chamber gradually fills with water, thus moving the obturator back onto the seat regardless.
Patent FR-2493261-A1 (FR)
Title: Sinking vessel location system - has seaworthy box automatically ejected at time of sinking and contg. battery powered radio transmitter and motor print system
IPC: G08B25/01
Filed: 1980-10-31
Abstract: The sinking vessel location system comprises a seaworthy box that is automatically ejected from the vessel at the time of sinking and that has a battery aboard the box for powering a radio transmitter that sends distress signals that enable a rescue vessel to locate the ejected box. The system employs a water-activated release mechanism and a stationary box with which the ejected box mates. When the release mechanism operates the box is ejected and at the same time the radio transmission commences. The release mechanism can also be used to release life savers and life boats. The ejected box has a printing system for registering any faults that may have occurred prior to sinking. The vessel may be provided with fire detectors, for example, and operation of a detector is registered along with the time of detector operation to thus provide a chronological log of all important events. The system also includes an automatic sea compass which continuously records longitude and latitude position.
Patent FR-2469486-A1 (FR)
Title: Yarn feed stop motion for flat bed knitting machine - prevents simultaneous presentation of two yarns
Inventor: BATES ARTHUR HAROLD
IPC: D04B11/20
Filed: 1980-11-14
Abstract: A plain flat-bed knitting machine with a selector mechanism for a variety of yarns has a safety cut-out which stops the machine if faulty selection offers two yarns simultaneously to the needles. A cut-out microswitch is operated by a rocking-lever assembly under the action of a pair of coil springs. The rocker is held in a disengaged position by a series of counter-springs whose combined force exceeds that of the operating springs. Each counter-spring is also attached to a yarn-selector lever, whose movement during yarn selection releases its counter-spring. If more than one of the counter-springs are relaxed simultaneously, the operating springs exert the greater force, and tip the rocker to operate the switch. The device prevents damage to the knitting elements which would be occasioned by a dual yarn-presentation.
Patent FR-2495990-A1 (FR)
Title: Ticket punching machine coding box - is installed on end of jaw and receives pins on other jaw of smaller dia. than alignment pins
IPC: B26F1/36
Filed: 1980-12-12
Abstract: One jaw (21) of the pliers has a first coding box (23) containing at least one punching hole (24,26,28,29,31,32) and the other jaw (36) has a second coding box (39) containing at least one punching pin in one of the positions (42-44) and (46-48). The dia. of the punching pin is smaller than the diameters of a pair of positioning pins (33,34) on the one jaw (21). The pins (33,34) are guided in bores (51,49) in the other jaw (36) on closing of the two jaws. Cards punched by the pliers can be identified with the person using the pliers by the number and position of the punched holes.

Title: Cylinder reactor pressure tank stress rods anchor - has deep and shallow intersecting grooves for rod ends in anchoring shoe
Inventor: LAUFS BERNHARD
IPC: E04H7/20
Filed: 1981-01-28
Abstract: Two layers of stressing steel are helically wound opposite ways, and there is an outside anchoring device for two ends of these fitted with anchor heads. These elements are used in stressing cylindrical containers, esp. reactor pressure tanks. The device comprises an anchor shoe (5), with two intersecting inlay grooves (7) for the ends of the steel bars (3,4) to be anchored, one being deeper than the other by one bar thickness. The shoe has a jaw (8) set on it, covering the grooves. The anchored bar ends have their anchor head (6) in front of the grooves. The ends are easily anchored, and easily released.
Patent FR-2501282-A1 (FR)
Title: Friction type rock stabiliser system - has elongated sleeve pressing against sides of borehole with slot allowing expansion
Inventor: CHAIKO WALTER MICHAEL
IPC: E21D21/00
Filed: 1981-03-05
Abstract: The stabiliser comprises a modified generally tubular friction rock stabiliser body for insertion into a borehole formed in a structure such as mine roof or side wall, or other subterranean opening. The body has a max. transverse dimension greater than borehole in which it is to be inserted, and requiring therefore considerable force to effect its borehole insertion. The stabiliser has a facility for attaching a pendant to it. An end of the body has a threaded nut fixed in it which receives a threaded, elongate, suspension bolt as the pendant. Thus, the pendant bolt, having a terminal drive head, can engage and pendantly support an ancillary article, such as a roof plate, remotely from the stabiliser body.

Patent FR-2504764-A1 (FR)
Inventor: ASCHWANDEN FELIX
IPC: H03L7/12
Filed: 1982-04-26
Abstract: A modulated carrier is supplied to a balance demodulator (18) which is also supplied with a reference carrier from a voltage-controlled oscillator (34), for generating an error signal which represents phase and frequency errors between the two carriers. The error signal is sampled in a sampler (22) and the samples are integrated in an integrator (30). So that the loop does not lock to a side band of the modulated carrier, an offset signal is output by a frequency scanning system (36) to the integrator (30). The modulated carrier can be a television signal which is sampled by frame and line blanking pulses and has a short and, respectively, long time constant for the frame and line samples. Once lock has been achieved, the offset voltage is removed with the aid of a circuit (40, 42, 38, C150).
