Title: Circuit de commande d'une charge inductive
Inventor: SICARD THIERRY MICHEL ALAIN
IPC: H03K17/06
Filed: 1989-04-06
Abstract: Le circuit suivant l'invention commande l'alimen­tation d'une charge inductive (1) par un transistor de puis­sance (2) du type MOS canal N placé du côté de la borne positive d'une source d'alimentation délivrant une tension +Vbat. La conduction du transistor (1) est maintenue à l'aide d'une tension de grille (Vs > +Vbat) fournie par un multi­plicateur de tension (3). A la coupure de cette tension, il y a blocage du transistor et décharge de la charge (1) qui développe rapidement une forte tension négative. Un transistor (N1) empêche alors la remise en conduction du transistor (1) tandis que, suivant l'invention, un transis­tor (P1) du type MOS canal P isole la grille du transistor (2) pour autoriser l'application sur celle-ci de la tension négative développée par la charge inductive.

Title: Differentiated collecting station for used plastic containers  with suction drawing
Inventor: GULMINI CARLO
IPC: B65F1/12
Filed: 1989-05-17
Abstract: The collection station essentially consists of an ideally cylindrical or parallelepiped compact mass body forming the collecting chamber for used plastic material containers and is equipped in different ways with a suction duct. The device can be directly laid on the ground and its emptying is nearly instantaneous by means of an aspiration air flux at high speed coming from a suction element, acting with automatic hooking, of a mobile drawing compartment which then transforms the above mentioned containers in recovered product for recycl­ing. In a version a station is foreseen which, on a base (1) leaning on the ground, uses a parallelepiped containment body (2) with loading mouths (3) and an inspection door (4). The plastic containers, or heterogenous plastic material, which have been let in, reach the bottom of the chamber (5) gliding on an inclined plane (6) and are stopped by a wall (7) with an inclination opposed to the preceding plane (6). On this site a suction duct (9), with catching mouth (8), is fitted with check and directional control valves (11). By means of the said suction duct (9) the containers are then taken away by means of a mobile operative compartment (17).

Abstract: This invention pertains to novel copolyesters consisting essentially of units (I), (II), (III) and (IV), and blends of these polymers and articles made from both. Units (I), (II), (III), and (IV) are present in specified proportions as defined in the description of the invention. The instant copolyesters display orientation in the molten state, good fiber ratings and high strength. Advantageously, the polymers of the present invention display a significant improvement in viscosity and moldability of the neat polymer. The polymers have excellent mechanical and surface properties including blister resistance, strength, toughness, and ability to vapor phase solder, and form strong fibers while still maintaining a high heat distortion temperature. They have melting points in the range of from about 250 to about 360 DEG C and are melt-processible. Advantageously, these compositions filled with about 30 weight percent of glass fibers display heat distortion temperatures of up to 240 DEG C, when measured under a load of 264 psi. The polymers may be blended to tailor properties. These polymers and blends may be used advantageously in producing fibers and in electrical equipment, electronic components and other end uses requiring moderately high temperatures.
