Patent FR-2422246-A1 (FR)
Title: Discharge suppressor for gas filled circuit breakers - is both magnetically and pneumatically operated with vents and baffles angled inward being displaced from contacts as circuit is broken
IPC: H01H33/91
Filed: 1979-04-05
Abstract: The automatic discharge suppressor is for circuit-breakers contg. a high dielectric strength gas, such as sulphur hexafluoride. The suppression mechanism is pneumatic and magnetic and relies on the axial movement of the two cylindrical electrodes (1, 2). The contact mating volume is surrounded by a magnetic winding (4) connected to an auxiliary electrode (3) at right angles to the switch axis. The auxiliary electrode is connected to the fixed contact and acts as a shunt to the two main contacts. The pneumatic effect is created by vents (10) and baffles (9) angled inward being displaced away from the contact areas as the circuit is broken.

Title: Multi-glazed window burglar alarm - with internal hygroscopic electrolyte strips as part of alarm circuit
IPC: G08B13/04
Filed: 1979-08-31
Abstract: A burglar alarm system for multiple-glazing windows with >=2 window panes, enclosing a dry air space (filled with dried air or contg. a dessicant such as silica gel), is based on arranging inside this space several strips, made of a hygroscopic electrolyte. A pref. material is neutral salt such as MgCl or MgSO. The strips are joined to electrodes which are insulated and form a part of an alarm circuit. This normally carries no current but when a window has been broken, the electrolyte becomes conductive and an alarm is sounded. Such an alarm system cannot be bypassed by a burglar and is less obstructive than wires for an acoustic alarm.

Title: Tear gas grenade with zigzag gas discharge - where hollow spheres contg. tear gas are ignited and blown out of grenade by explosive charge
Inventor: METAYER JEAN
IPC: F42B30/04
Filed: 1980-07-25
Abstract: The grenade consists of a tubular can contg. at least 1 tear gas charge inside a hollow sphere provided with at least 1 hole so the gas travels along uncoordinated zigzag paths after the grenade is ignited. The grenade has a delayed igniter plug, and an explosive charge driving the sphere out of the can. In one pref. grenade, two hollow spheres, each contg. a tear gas charge ignited by a relay, are ejected by another, explosive charge.
