Patent CA-1294228-C (CA)
Title: Hoses
Inventor: HARCOURT ROBERT M
IPC: F16L11/08
Filed: 1987-05-27
Granted: 1992-01-14
Abstract: ABSTRACT         A method of making a hose is disclosed which comprises the steps of forming a tube by extruding onto the internal and ex-ternal surfaces of a tubular jacket a covering of rubber or curable elastomeric material, confining the jacket and the covering in a tubular restraining sheath or mould of larger internal diameter than the external diameter of the jacket and its covering, curing the covering by means of heat and pressure applied within the tube so that radial expansion of the tube during curing urges the tube into tight engagement with the sheath or mould which substantially prevents further radial expansion of the tube, and removing the sheath or mould on completion of the curing process.  A tube made by the invention has a woven or braided tubular jacket having a lining on its internal surface and a covering on its external surface, which lining and covering are formed from rubber or elas-tomeric material, a first set of perforations extending outward through the lining and terminating at the jacket, and a second set of perforations extending through the covering and terminating at the jacket, which perforations are staggered with respect to the perforations of the first set.

Title: Plastic foam container for the densification of powder material
Inventor: ROZMUS WALTER J JR
IPC: B29C43/10
Filed: 1988-01-08
Granted: 1992-04-28
Abstract: ABSTRACT          A method and container for densifying a powder (14) of metal or non-metal.  The powder is disposed in a sealed container (12) which is encapsulated in a pressure transmitting medium (16) contained within a pot die (26) of a press.  A ram (24) enters the pot die (26) and applies a force to the pressure transmitting medium (16) and the container (12).  The pressure transmitting medium (16) transmits pressure omni-directionally about the container (12).  The container (12) has an impermeable, cellular structure (12) that collapses and permanently deforms as the powder (14) compacts.  The container (12) does not substantially expand to its initial shape after being removed from the pressure transmitting medium (16) and therefore saves the compacted powder (141) from resilient forces of the container (12) tending to rebound the container (12) to its initial shape.     35,999-F
