Title: Gas-insulation electric circuit breaker with electromagnetic blasting coil for rotation of the arc
Inventor: BARRAULT MICHEL
IPC: H01H33/18
Filed: 1986-05-26
Abstract: The arc extinguishing device 30 of an SF6 insulated circuit breaker includes a pair of separable contacts 12, 14, an electromagnetic coil 16 for rotating the arc, and phase-shifting means cooperating with the coil 16 in order to preserve a sufficient magnetic field at a time favourable to the extinguishing of the arc, in this instance on the passing of the current to zero. The coil 16 is axially framed by a pair of short-circuited annuli 50, 52 intended to prevent any spatial deformation of the magnetic field within the arc zone 18, independently of the instant of the phase of the AC current to be interrupted. Application: medium- or high-voltage circuit breaker or switch.

Patent FR-2609090-A1 (FR)
Title: System, for closing or locking any sort of door, which locks the bars with the frame
IPC: E05B47/00
Filed: 1986-12-29
Abstract: System, for closing or locking any sort of door, which locks the bars with the frame. It is operated by radio control by typing the formula on a pocket keypad. The system is controlled by one or more motors, powered by solar collectors and (or) batteries and (or) electricity. The bars move horizontally and vertically on slideways. The parts of the bars which lock the door have cutouts, or shapes, which correspond to the shapes in the part of the system within the frame. The operation is performed by moving the bars horizontally and vertically until complete locking is obtained. The system makes the door and frame into a single unit, leaving no possibility for forcing the door. In accordance with the same system, mention is made of two other methods, in which, by virtue of the fact that a hole is made at the centre of the bar, a pin can be inserted, which allows the bar to be screwed into the frame. Alternatively, a small bar can be rotated, so as, by virtue of its horizontal position, to block the system. These two methods can be adapted to existing closure or locking systems.

Patent FR-2621430-A1 (FR)
Title: Reversible generator of push-pull type with stator excitation
IPC: H02K57/00
Filed: 1987-03-16
Abstract: The present invention relates to a reversible generator, the advantages of which are that it is capable of being an AC electrical generator; or an AC or DC motor, without wiper contacts. Its electrical and mechanical composition, through the arrangement of various stator elements A and D, and rotor elements E and C, through the succession of the inductions between A and E, D and C, A and C, D and E, provides the abbreviation PUSH-PULL. Modulation of the electrical voltages and currents of certain stator circuits makes it possible to control the magnetic fields exerted on the various magnetic and electric parts of the machine, be they stator or rotor parts, whence the notion, "stator excitation". Mechanical adjustment, and the magnetic excitation circuits, such as permanent magnets, will make it possible, as desired, to produce an EMF, and hence to produce constant excitation in the guise of electrical generator, to produce an induction between two half-cycles of the supply; in the guise of AC motor, through the exploitation of the rotating fields.
