Title: Dispositif de verrouillage d'une enveloppe contenant des matieres pyrotechniques.
Inventor: BRUNO BOISSIERE
IPC: F42B39/20
Filed: 1991-11-29
Abstract: L'invention se rapporte à un dispositif de verrouillage d'une enveloppe (1) contenant des matières pyrotechniques. Des moyens d'inflammation (4) étant en position pour enflammer les matières pyrotechniques (2), cette inflammation est provoquée par l'activation des moyens d'inflammation (4). Tant que les moyens d'inflammation (4) n'ont pas été activés, l'enveloppe (1) est maintenue solidaire d'une élément de fermeture (3) uniquement par des premiers moyens de verrouillage (5, 6) de 'telle façon que pour des pressions internes de l'enveloppe (1) supérieures à une pression donnée (Po ), l'enveloppe se désolidarise de l'élément de fermeture (3). Dès que les moyens d'inflammation (4) ont été activés, l'enveloppe 1 est maintenue solidaire de l'élément de fermeture (3) par des seconds moyens de verrouillage (7, 8) pour des pressions internes de l'enveloppe (1) supérieures à la pression donnée (Po ). Application: réduction des effets dangereux provoqués par activation accidentelle de matières pyrotechniques contenues dans une enveloppe de confinement.

Patent FR-2688787-A1 (FR)
Inventor: SOPHIE SUC
IPC: C07H15/04
Filed: 1992-03-23
Abstract: This process consists in reacting a cationic starch with hydrogen peroxide and hydrobromic acid or bromine, in aqueous solution, so as to oxidise selectively the hemiacetal groups of the cationic starch and optionally the hemiacetal groups of its products of acidic hydrolysis, to carboxylic groups. The carboxylic and cationic amphoteric starch thus obtained is characterised in that its carboxylic groups originate from the selective oxidation of the hemiacetal groups of the cationic starch and, optionally, of the hemiacetal groups of its products of acidic hydrolysis.

Title: Vehicle seat with integrated raising seat to form child's seat - has front section of seat base, which can be lifted by linkages to fit above fixed section of base, to form seat for baby or child
Inventor: PETER LINDE
IPC: B60N2/30
Filed: 1992-06-15
Abstract: The vehicle seat is formed from a seat base (2), for at least one person, a seat back (4) and a raising seat (3), for a baby or a small child.  The raising seat consists of a seat support (32) and squab, fitted to the main seat frame by links (27 and 28), which allow the raising seat to occupy and lock into a retracted position for normal use and a raised position for use by a child. The seat back (4) has a concave shape and the central lower panel (4c) contains the adjustable harness (6).  The raising seat (3) is formed as a separate element from the fixed seat base (2). It has the same structure and shape as the seat base, but the rear edge has a convex profile (11), which is complementary to the front edge of the fixed seat base.  The frame has a base plate (26) fitted beneath the raising part of the seat, to form a foot rest for the child occupying the raised seat. USE/ADVANTAGE - It provides a good protective seat for a child, when in the raised position, without affecting the comfort of the adult user in the lowered position.

Title: Circuit breaker for electricity distribution - has sliding contact section with inner tube and outer circular chamber forming gas suction section
Inventor: DENIS DUFOURNET
IPC: H01H33/90
Filed: 1992-10-06
Abstract: The circuit breaker is sealed in an outer wall (1). A fixed contact section is made up of an inner conducting tube (4) and an outer surrounding wall (2). The outer surrounding wall is metallic with an extending isolating section (3). The moving contact section has an inner tubular section, fitting into the static section with an outer surrounding section (5). An inner chamber (V2) is formed between the isolating section and the moving section. The enclosure is filled with gas. A low discharge arc is accompanied by the moving plunger section being pushed back and sucking gas to the chamber via inlets (11), with a flow of gas from the outside of the chamber (18). A high discharge arc increases the pressure around the contact region, in which case gas is sucked into the chamber (V2), and also expelled to the outside of the chamber via the fixed section outlet. ADVANTAGE - Suction chamber allows good operation with low currents at medium and high voltages.

Title: Anti-theft device preventing a portable welding set being put into operation
Inventor: GEORGES LOUAIL
IPC: H04L9/32
Filed: 1993-10-21
Abstract: This device applies to a portable welding set, with a power inverter (21) and an electronic control and monitoring unit (16) sending control pulses (I1, I2) to the inverter (21). A decimal numerical access code (N) with several figures, inserted manually by the user by the use of means (12 to 15), is compared with a number stored in memory in a microprocessor (32) which sends out an internal binding numerical code (n) with several bits in the event of coincidence. The internal code (n) is sent, by a link (33), to means (34) for recognising this code (n), which compare it to a code specific to the appliance, and which allow or prevent the sending of control pulses (I1, I2) for the inverter (21).

Title: Vehicle windscreen wiper with variable wiping pressure adjustment
Inventor: JOURNEE MAURICE
IPC: B60S1/34
Filed: 1994-06-07
Abstract: The windscreen wiper arm (14) is mounted so as to pivot on axis Y-Y, which is provided by the drive head (12). A spring (36) acts between the drive head and the wiper arm to apply a force along a line of action (D) to produce a cleaning pressure onto the windscreen. This line of action (D) does not pass through the pivot axis, Y-Y. The distance between the line of action of the force and the pivot axis can be varied by means of a tipping adjuster (46), which is mounted so as to link from the pivot axis, Y-Y, and the spring carrier (52). The tipping adjuster is designed to pivot around an axis, Z-Z, which is parallel to the main pivot axis, Y-Y, when adjusted by means of the adjusting screw (60).
