Title: Pressure balanced inner chamber of a drilling head
Inventor: BAILEY THOMAS F
IPC: E21B33/08
Filed: 1994-01-14
Abstract: ABSTRACT OF THE DISCLOSURE      A system for maintaining an optimum pressure balance within an inner chamber of  a drilling head for  improved seal  life and integrity.  The system maintains a pressure differential across the seals thereby preventing well fluids from contaminating the seals and improving their useful life.  The drive ring of a drilling head is rotatably supported by a series of bearings disposed within a bearing chamber.  The secondary chamber of the drilling head is sealed to prevent contaminants  from entering the chamber and fouling the seals.  The seals withstand the borehole well pressures to prevent the introduction of contaminants,  by maintaining a pressure  differential  across  the  seals.    The  present  system compensates for variations in the borehole pressure.  A pressure compensator is in communication with the borehole to activate a lubricant pump for increasing lubricant pressure within the inner chamber in response to increased borehole pressures.   A relief valve associated with the inner chamber relieves pressure in the seal chamber to maintain lubricant pressure at optimum levels when borehole pressure decreases for controlled operation of the seals. Additional check valves are included in the inner chamber to control the chamber pressure while preventing contamination of the lubricant.

Abstract: A method and apparatus for manufacturing a plug-type chamber to accommodate at least two floating plugs for use in the cascade drawing of tubes are disclosed.   A starting tube is first fixed in position by a clamping and denting device.  A necking-down ring is subsequently moved with the help of a necking-down cylinder along a freely projecting end section of the starting tube.  A punch is then pushed with the help of a cylinder into the end section of the tube.  When the punch has reached its end position, the necking-down ring is pulled over the end section of the tube, and the outside diameter is reduced to its original size.     The  punch  is  subsequently  removed,  and  two indentations are made on the periphery of the end section of the starting tube with the help of the clamping and denting device.  Together with a drawing point produced through the reshaping of the unattached end of the starting tube, these indentations then form a plug-type chamber, in which several floating plugs are embedded, which interact with drawing dies during the cascade drawing operation.

IPC: A61F13/20
Filed: 1994-07-07
Abstract: A process for injection molding arcuately-shaped hollow articles is disclosed. The process includes the steps of positioning a stack mold into an injection molding machine. The stack mold has first, second and third mold blocks with the first mold block positioned between the second and third mold blocks. Each of the mold blocks has a plurality of cavities formed therein. The cavities formed in the first mold block are designed to mate with the cavities formed in the second and third mold blocks when the stack mold is closed to form a plurality of arcuately-shaped cavities. The stack mold further contains a pair of slide carriers movably connected tr each of the second and third mold blocks and a plurality of inner cores secured to each of the slide carriers. The stack mold is closed by first moving both of the pairs of slide carriers such that each of the inner cores is positioned within one of the arcuately-shaped cavities to form a hollow interior in each of the molded articles.        The first and second mold blocks are then moved against the third mold block. Molten material is introduced into the arcuately-shaped cavities and is allowed to solidify. The stack mold is opened by moving the first and second movable blocks away from the third mold block and then moving both of the pairs of slide carriers outward to remove the inner cores from the arcuately-shaped cavities. The injection molded articles are then removed from the stack mold.
