Title: High voltage generating circuit for IC engine ignition - has lower voltage sustaining discharge and high voltage to start discharge through generator active between electrode gaps
Inventor: MERE HENRI COURIER DE
IPC: H03K3/57
Filed: 1981-11-13
Abstract: The circuit produces an instantaneous high voltage from a low continuous voltage includes two main components. A first signal generator (I) applies to the ionising gap (20), a voltage which is insufficient to spark across the space, but which is adequate to maintain a discharge during a specific time interval. A second signal generator (II) applies a voltage higher than the necessary discharge starting voltage each time a synchronised pulse is required. A 'valve' circuit (III) is connected to the output of the first generator (I) so that the signal encounters low resistance in reaching the discharge space, but the second generator encounters a large resistance on the reverse path. A second 'valve' circuit (IV) serves the same purpose for the second generator.

Title: Integrated circuit magazine filling indicator for automatic inserter - has pointer pivotable by component-pushing plunger to adopt one of two positions according displacement
IPC: G12B11/04
Filed: 1981-12-23
Abstract: The device comprises a swivelling pointer (1) which is in contact, at a given place (1'), with a component (8) of the magazine (9). In presence of a component (8) at this place (1'), the pointer (1) is in one position; in the absence of components, it is in another position which is visually different from the first. This simple device is useful in the automatic machines which insert integrated circuits. It is used to signal that the secondary magazines which supply the primary magazines are almost empty. In one application, the pointer (1), fitted on a support (11), swivels by gravity around an axle (3) between the two positions. A stop (4) limits its movement.

Title: Electrostatic sepn. of particles from clay slurries etc. - uses rotating disc partly immersed in slurry to gather polarised particles
Inventor: RICHON DENIS
IPC: B28C1/08
Filed: 1982-01-18
Abstract: Process and installation are claimed for drying and concentrating suspended particles in a slurry, e.g. of clay for ceramics. A continuous electric current is passed through a zone of the suspension in order to polarise the suspended particles. The particles then accumulate on a positive or negative electrode of the source of current used to polarise the particles in suspension. The accumulated particles are gathered separately from the electrode e.g. by means of a doctor blade. Pref. the area of electrode from which particles are gathered emerges from the surface of the slurry before particles are scraped off. In partic. the particle gathering electrode may be a metal disc rotating about its central, horizontal axis. The disc gatheres polarised particles on its immersed area which then moves out of the slurry so that particles can be scraped off for collection. The speed of rotation of the disc can pref. be varied w.r.t. density, moisture content and type of slurry. The process and installation are for sepg. and dehydrating particles suspended in a slurry, esp. particles of clay required for the mfr. of ceramics, paper, textiles, etc. The process can also be used for the purificn. of waste water and the prepn. of animal feeding stuffs. Installation is compact, simple and can be economically applied in small scale industry. The complications of steam or hot water drying circuits are avoided.
