Inventor: PEROL PHILIPPE A
IPC: H02M3/28
Filed: 1992-02-05
Abstract: Ce convertisseur comprend: un transformateur avec deux primaires (P1, P2); une source de tension (V in) dont l'une des bornes est reliée au point milieu; et deux commutateurs (T1, T2), montés en série entre l'autre borne de la source et un primaire, qui présentent une capacité parasite imposant un temps de transition entre ouverture d'un commutateur et fermeture de l'autre.   Le transformateur est réalisé sur un circuit magnétique à entrefer et chaque primaire comporte un nombre de spires déterminé essentiellement en fonction du niveau des pertes au sein du circuit magnétique, la dimension de l'entrefer étant ajustée, compte tenu de ce nombre de spires et de la fréquence de travail, de manière à réduire l'inductance de magnétisation du transformateur à une valeur telle que ledit temps de transition soit inférieur à un seuil donné correspondant à la limite tolérable du facteur de forme.

Title: Electrical house-wiring system
Inventor: FREUNDNER HASSO
IPC: H02G/
Filed: 1991-03-23
Abstract: The installation concerns an electrical house-wiring system in which plug blocks are mounted in sockets in the floor by virtue of their special design. This makes it possible not only to combine these sockets mechanically by simply plugging in a usually three-pin bridge unit in the form of a pin-and-socket connector, but also to combine them electrically without any loss of time. To this end, each unit in a combination has facilities for directly connecting up appliances to be installed. The appliance connection can take the form of a pre-assembled three-wire cable harness. In addition, at least one take-off line can be taken from each of these combined sockets to supply power to other socket systems. In general, with this installation technique no wiring work is necessary on the building site to connect up the individual sockets within a combination to their power supply. The generally individually laid connector clips previously used are no longer necessary.  Sockets of this type can be used not only as appliance sockets or appliance connector sockets but, if required, also as pure connector sockets.

Abstract: A spout provides an extended sheet of flowing water for a shower nozzle or the like, by employing a single nozzle spaced from a spherically curved shield to create a sheet.      The nozzle may have a noncircular cross-section to increase the lateral water flow out of the nozzle to provide a more uniform sheet after the focusing effect of the shield. The lower edge of the shield is sharpened to prevent the attachment of the sheet to the edge such as might cause an undesired spray of water droplets.

Title: Method of producing prestressed diamond composite films by chemical vapor deposition and articles produced therefrom
Inventor: ANTHONY THOMAS R
IPC: C04B35/80
Filed: 1992-12-17
Abstract: RD-21,415 METHOD OF PRODUCING PRESTRESSED DIAMOND COMPOSITE FILMS BY CHEMICAL    VAPOR DEPOSITION AND ARTICLES      PRODUCED THEREFROM                Abstract of the disclosure A method is disclosed for producing prestressed diamond composite articles having a reinforcing member therein. A mixture of a carbon compound such as methane and hydrogen is introduced into a conventional CVD chamber containing the reinforcing member maintained at a typical chemical vapor deposition temperature. The reinforcing member is centrally positioned between banks of filaments to substantially symmetrically deposit a diamond layer on the reinforcing member having a thermal coefficient of expansion equal to or greater than that of diamond. During the cooling of the diamond composite article, after a desired thickness of diamond layer is reached on the reinforcing member, it contracts more than the diamond layer. As a result, the diamond layer is prestressed by the compressive stresses provided by the thermal contraction of the reinforcing member. Additionally, since the reinforcing member is centrally disposed within the diamond article bending moments which are typically present in a conventionally made diamond article are absent. Thus, a crack free and distortion free diamond composite article having an improved structural strength is produced.

Inventor: KUZIK LARRY J
IPC: B65G21/00
Filed: 1993-01-13
Abstract: A method for deploying a belt on a large conveyor belt system which extends down slope.  A run of the belt is positioned at an upper position along the slope, and is engaged with a controllable brake which is configured to permit selective adjustment of the braking force which is exerted thereby on the belt.  The belt is then lowered along the conveyor belt system using the weight of the run, and the rate at which the run of belt advances is controlled by selectively adjusting the braking force which is exerted by the controllable brake.  The runs of belt may be lowered from adjacent high points in the conveyor belt system and spliced together where these meet in the valleys between the high points.  The controllable brake assembly may be made up of a plate which extends across the belt and an inflatable bladder which is positioned on top of the plate and beneath its support, so that as fluid pressure is selectively added to the inflatable bladder, this biases the plate against the belt so as to control the braking force which is exerted by the plate against the belt.

Title: Automotive air suspension system
Inventor: THACKRAY DONALD S
IPC: B60G11/27
Filed: 1993-02-17
Abstract: ABSTRACT OF THE DISCLOSURE   A conventional leaf spring suspension system as applicable to pick-up trucks, vans and motor homes produces a harsh ride and is unable to compensate for changes in vehicle ride height and quality brought about by uneven or heavy vehilcle loading conditions. A more effective suspension is achieved by incorporating air springs to compliment the existing leaf springs thus providing the ability to adjust ride height and hence, ride quality. This is accomplished by replacement of existing suspension components, such as shock absorbers, with, on the front suspension, an air spring and various attachment brackets and, on the rear, an air spring in combination with a sub-frame and torque arm linked cross beam, carried between which is a low pressure air spring.
