Patent CA-2081494-A1 (CA)
Inventor: SINHA UDAY K
IPC: B22F3/20
Filed: 1992-12-21
Abstract: Apparatus for continuously extruding powdered, comminuted, or particulated feed material which includes a conform extrusion machine or the like in cooperation with a forming wheel rotatably disposed within a portion of said Conform wheel to compress the feed material into a compacted feedstock. Compressing of the feed material into a compacted feedstock enables uniform and reliable conveyance of the feed material into the extrusion machine. An auxiliary shoe member conforming to the outer periphery of the forming wheel and to the Conform shoe is included to separate the. compacted feedstock from the forming wheel. The auxiliary shoe directs the compacted feedstock into a passageway formed by the Conform machine extrusion wheel and extrusion shoe. As the respective wheels are rotated the forces on the compacted feedstock heat it and cause it to yield and flow through an extrusion chamber adjacent the Conform machine abutment; it is then extruded from a die in the wall of the chamber. A temperature control system in heat exchanging relationship with the chamber in proximity to the die maintains a desired temperature uniformity in the chamber material to provide uniformity of grain size in the extruded product. Temperature control systems may also be provided for the feed material and for metallurgical control of the extruded product.

Title: Spiral wound separation device and method of making same
Inventor: HOPKINS DAVID H
IPC: B01D63/10
Filed: 1993-07-07
Abstract: SPIRAL WOUND SEPARATION DEVICE   AND METHOD OF MAKING SAME               ABSTRACT OF THE DISCLOSURE A sandwich of a permeate fabric material within a folded sheet of semipermeable membrane is spirally wound together with a sheet of porous feed pathway material about a mandrel which, upon its removal, provides a central hollow region in the wound element.  A single band of adhesive seals the outer end of the envelope, and once wrapping is completed, a thin layer of porous tape holds the winding tight.  A porous small diameter tube is inserted into a pocket adjacent the fold in the semipermeable membrane material near the center of the winding and serves as a permeate discharge conduit. Axial ends of the spirally wound subassembly are sequentially potted in resin to complete the basic fabrication of the element.  Communication with the feed pathway material is provided by drilling through the resin into the center hollow region.  The spirally wound element can be used as a replacement cartridge for a device having a permanent housing, or it can be integrally bonded within a surrounding pressure vessel assembly to form a disposable water purification unit. Feedwater supplied to the open center region flows spirally outward, while permeating purified water flows spirally inward to the porous tube which serves as a pure water discharge conduit.

IPC: A61H1/02
Filed: 1993-08-11
Abstract: A passive exercise unit for manipulating legs and/or arms of a patient to achieve improved circulation, development of muscles and achieve full extension of otherwise crippled limbs.  A motor-driven crankshaft member carries leg cradles on opposite sides of a housing that is supported on a base.  This base can be, if desired, releasable fastened to a bed supporting the patient.  These cradles are pivotally supported, and their position relative to the crankshaft permits a selected degree of motion for the patient's legs.  An upwardly-extending frame carries arm exercising components that include cables to hand grips. Motion for these cables is achieved by connections to the crankshaft used for the leg cradles.  This frame can be folded against, or stored in, the housing when not in use.  In a preferred embodiment there are glove units to assist in the holding of hand grips by the patient.
