Title: Pyrotechnic safety device for a projectile
Inventor: CASTERA ANDRE
IPC: F42C15/18
Filed: 1983-02-02
Abstract: Pyrotechnic safety device for a projectile. The device comprises, inside a body 1, 4 having a channel 7, a detonating fuse 24 and a material mass 25 movable relative to the body 1, 4 between a safety position, in which this mass 25 is interposed between the detonating fuse 24 and the channel 7, and a priming position, in which it is retracted and opens communication between the detonating fuse 24 and the channel 7; this material mass 25 has a deformability correlated with the explosive energy released by the ignition of the detonating fuse 24, in such a way that, if such an ignition occurs when said mass 25 is in the safety position, this mass 25 is deformed, without breaking, in order to come into intimate contact with the body 1, 4 on the periphery of the channel 7, and thus closes the latter off sealingly relative to the gases resulting from the explosion of the detonating fuse 24. The invention is used to improve the pyrotechnic safety of projectiles.

Title: Auricular-ventricular pacemaker
Inventor: JACOBSON PETER M
IPC: A61N1/362
Filed: 1983-04-29
Abstract: The pacemaker detects retrograde tachycardia at any frequency and prevents or interrupts retrograde tachycardia when the retrograde conduction is outside its natural refractive phase or, when caused by the pacemaker itself, changes its parameters.

Title: Reversible mechanism for controlling a multipole limiter circuit breaker
Inventor: BATTEUX PIERRE
IPC: H01H77/10
Filed: 1983-10-21
Abstract: The invention relates to a reversible mechanism for control of a circuit breaker. The mechanism 12 includes a knuckle 44 associated with an automatic trip lever 56 and with a switching bar 28 which is common to all the contact arms 26 of the various poles. The bar 28 is equipped at the level of each pole with a drive member 110 arranged at a predetermined place in the electrodynamic opening stroke of the corresponding contact arm 26. The electrodynamic opening of the contact arm 26 of a faulty pole causes a rotation of the bar 28 and a separation of the contacts 14, 16 of all the poles prior to the intervention of the trip. The angle alpha of offset of the link rods 46, 48 of the knuckle 44 lies, in the closure position, between 10 and 20 degrees. The point P of pivoting of the contact arms 26 coincides with the axis of rotation of the bar 28. Application: low-voltage multipole limiter circuit breakers.
