Abstract: Un dispositif servant à réduire la tension d'une corde ou objet analogue comprend une plaque d'ancrage (8) et un organe de serrage (10) composé de deux éléments à piston et cylindre (34), deux éléments de serrage (14) et un circuit de commande hydraulique qui commande le serrage de la corde ou objet analogue en fonction de la tension de celle-ci ou celui-ci. La tension P produit la séparation du dispositif de serrage (10) et de la plaque d'ancrage (8), ce qui provoque la compression du fluide dans les chambres (46). En conséquence, les béliers à double action (30) sollicitens les éléments de serrage (14) l'un vers l'autre sous l'effet des cames (26). Si la tension dépasse une valeur de seuil, le fluide pressurisé déclenche la soupape sensible à la pression (54), ce qui permet à ce fluide pressurisé d'inverser la soupape d'inversion (55), relâchant ainsi temporairement le serrage de la corde ou de l'objet analogue.

Abstract: The invention relates to a hydro-electric plant in which turbine sets (5, 6, 7) provided with a braking device are employed. The turbine sets are situated in shafts (2, 3, 4) with inlet openings (9, 10, 11) at different levels, which are in turn arranged in a collecting basin (1). The shafts are of open design and allow the liquid to flow in freely. A water level detector (13) which records the water level in the collecting basin (1) releases a braking device of the respectively associated turbine set at water levels assignable to the respective shafts and thus allows them to be put into operation. Similarly, the individual turbine sets are succesively disconnected from the mains with the aid of the braking device from certain respectively assignable and measurable water levels as the level falls. <IMAGE>

IPC: B65F1/14
Filed: 1992-02-20
Abstract: The invention relates to a refuse container (1) for degradable waste, the interior of which comprises two vertically arranged volumes (5, 16), whereby it is intended that the liquid received with the degradable waste should collect in the lower volume (16), from where it can also be removed. On the one hand, this volume should be large enough to be definitely able to accommodate the liquid received, on the other hand emptying of the liquid section and of the refuse container itself should be easy and trouble-free, without backmixing of the waste with the liquid occurring. To this end, the lower volume (16) is separated from the rest of the container casing by means of a forked grid (14), which is normally horizontal, but which is pivoted about a horizontal axis in the container casing during emptying. Reliable separation of solid and liquid waste and complete emptying of waste from the refuse container are achieved in this way. <IMAGE>

Abstract: Disclosed is an electromagnetic induction steam generator which is compact or ultra-compact and highly efficient, being capable of continuous operation, intermittent operation and empty-heating operation. Magnetic flux passes through a closed magnetic circuit comprising the two leg iron cores (2a and 2b), the heater (1) and the yoke iron core (5) after a low-frequency alternating power source is supplied to the electric wire(3) and the coils (4a and 4b). Joule heat is generated inside the heater (1) due to the permeation of magnetic flux. Therefore, when fluid such as water is supplied from the fluid supply port (6), it is heated and becomes steam within the heating chamber (10). The steam then emerges from the steam output port (7).

Inventor: WONG STEPHEN
IPC: H01L27/06
Filed: 1992-04-24
Abstract: In power integrated circuits having both control circuit components and at least one power device, the circuit components are typically isolated from the power device by placing them in separate "wells" of opposite conductivity type to that of the underlying substrate. However, when these power integrated circuits are used in applications (such as automotive electronics) where supply voltage can be inadvertently reversed, large and potentially damaging currents can flow through the circuit components. In order to prevent such large reverse currents from flowing, an additional p-n junction is incorporated within the circuit "well", thus preventing undesirably large reverse current flow. However, introduction of this addition p-n junction creates a vertical transistor within the device, thus creating another potentially damaging current path and also creating potential reverse breakdown voltage problems. In order to alleviate these problems, a reverse voltage protection circuit employing two series-connected MOS switching transistors is used to shunt current away from the base of the vertical transistor. Additionally, the effectiveness of this reverse voltage protection circuit can be improved by the addition of an integrated bias circuit that serves to generate a gate bias voltage that further enhances the breakdown characteristics of the circuit.

Abstract: An optical fiber cable closure (20) includes a cable termination assembly (26) and a cover (28) into which the termination assembly is inserted. The cable termination assembly includes an end plate assembly (34) through which distribution cables (21,22) to be spliced extend. From the end plate is cantilevered a distribution portion (106) which supports an optical fiber organizer (115). Mounted on the fiber organizer adjacent to a longtudinal edge thereof are a plurality of stacked organizing modules (120,120). Each module includes a plurality of nests (134-134) for receiving splicing devices such that the axes of the fibers in the devices are parallel to each other and to an axis of the closure. Optical fibers from each incoming cable are routed in individual bundles or as ribbons from the distribution portion to selected ones of the modules. The stacked organizing modules are held spaced above the fiber organizer to allow fiber to become routed therebetween thereby allowing a radius of curvature which exceeds that if the fiber had been routed between the stack of modules and an opposite longitudinal edge.
