Title: Membrane seal for a removable bottom founded structure
Inventor: HALL LARRY
IPC: E02B17/00
Filed: 1987-05-25
Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE         The Removable Bottom Founded Structure (RBFS) is an offshore platform for petroleum drilling and producing operations which is deployed in waters with severe weather and iceberg conditions.  The structure is normally held down by gravity, but during the deballasting procedure a hold-down system is employed to keep the platform on the subbase until site evacuation.  The system that is used to hold the platform down onto the subbase is located where the platform meets the subbase.  It operates on the prin-ciple of hydrostatics.  On the underside of the columns, there are multiple chambers which may be evacuated by pumping and which are vented to the outside atmosphere. Flexible seals that define these chambers are positively engaged by water to create a fluid-tight seal so that no seawater will enter the evacuated chambers.  The reduction of the buoyancy forces will hold the platform onto the subbase until such time as the platform is totally deballasted.  Once that has occurred, the hydrostatic hold-down system is disengaged and the platform will quickly rise to the surface.

Title: Slidable truck cover assembly
Inventor: WEAVER ROBERT C
IPC: B60J7/06
Filed: 1987-07-21
Granted: 1992-05-12
Abstract: SLIDABLE TRUCK COVER ASSEMBLY          ABSTRACT:      A cover assembly is installable on the open bed of trucks, adapted to be mechanically drawn over or withdrawn from the top of the truck bed by means of a pulley operated looped cable attached to a movable tarpaulin.  The tarpaulin covers and seals the top portion of the side walls, front and rear walls of the truck when in the drawn position, thereby completely sealing the interior of the truck bed from the outside.  The assembly reduces driver fat-igue in covering the truck bed as well as reducing the risk of driver injury.

Title: Control device for hydrostatic steering means or the like
Inventor: JORGENSEN ERIK C
IPC: B62D5/097
Filed: 1987-09-11
Granted: 1991-02-26
Abstract: Abstract A control device for hydrostatic steering means comprises two rotatable slide elements (32, 33).   Between the connections on the pump side and the container side, they possess a bypass throttle (17) which is open in the neutral position.    The bypass throttle (17)  has two throttle positions  behind  each  other  in  that  two  control  grooves  (56,  57) mutually offset in the direction of rotation are interconnected in one slide element (33) in the neutral position by a bridging space (58) in the other slide element (32).    This results in a marked reduction in noise.     Fig. 3

Abstract: Abstract of the Disclosure The present invention is directed to the construction of an integrated circuit chip, and to the method of making such a chip from a plate or wafer.  In accordance with the present invention a chip is formed to have conductive edge portions disposed on an insulator surface, which  portions optionally may  further  be expanded  into  a  pad. The insulating material electrically  isolates the  conductive edge portions from the semiconductive body  of the chip.          The invention may be implemented  in redundant fashion  to effect a multiplicity of electrical  connections to a  set of bulk semiconductor  integrated circuits  formed on  the wafer.    Each exposed conductive  portion on a  chip edge  and its optional surrounding  conductive pad  may be  reliably surrounded by  insulator  so  that  electrical  shorts  to non-insulating regions are not experienced.  By this  edge surface  structure  integrated  circuit  elements  may  be stacked in  an array,  and electrically  connected at  the edge surfaces thereof, without hazard that any  electrical regions  of  the  integrated   circuit  elements  may   be contacted, save intentionally  through a conductive lead or film connected to the pads.

Abstract: Long service lives of the plate set are required for economical operation of the installation, particularly when casting strands with three-plate sliding gate valves for controlling the melt supply into the mould. Premature wear points caused by sharp deflections of the melt flow and resulting high flow pressures in the melt flow passage are to be reduced by using simple means.  These are characterised by an axial offset of the flow bore in the fixed outlet plate with respect to the flow bore in the fixed inlet plate in the closing direction of the sliding plate and a conical widening of the flow bore provided at least at the inlet side which produces a substantially unimpeded flow of the melt current through the sliding gate valve to the outlet tube.
