Patent CA-2367526-C (CA)
Inventor: CARISELLA JAMES V
IPC: E21B33/127

Granted: 2006-01-17
Abstract: A thermal compensating apparatus method for maintaining a substantially constant fluid pressure within a subterranean well tool of the type that includes a bladder (25) that is selectively expandable upon the introduction of pressurized actuation fluid for actuating said tool at a location in a well. A body includes first and second fluid chambers (49, 21). The first fluid (49) chamber houses a substantially incompressible fluid and communicates with the actuating fluid used for activating said tool in the well. The second fluid chamber is charged with a compressible fluid. Both chambers (21) define first volumetric sizes within the body upon actuation of said tool in the well. The fluid chambers are operatively connected to each other without transmitting fluid there between so that changes in the volumetric size of the first chamber caused by temperature variations in the actuation fluid will change the volumetric size of the second fluid chamber for maintaining the actuating fluid at a substantially constant pressure.

Abstract: "The present invention (An Economical Soap Bar and the method for producing the same) relates to a process of improving a regular soap bar. The process involves coating all sides of the soap bar, with the exception of one larger side, with a thin layer of a waterproof material with or without additives, such as coloring or essences.  The improved soap bar has an advantage of lasting longer than regular soap bar, because only one side (the uncoated side) is susceptible to water during use. In addition, the improved soap bar does not become excessively soft in places and regions with high humidity due to its waterproof coating. The waterproof material can be, but not be limited to a synthetic polymer waxes, natural bee's wax, micro-crystalline wax, petroleum jelly, snow white petroleum, paraffin wax, gel wax and the like. The soap bar, in connection with the present invention, means any soap use for personal hygiene."

Title: Aggregate-free urate oxidase for preparation of non-immunogenic polymer conjugates
Inventor: SHERMAN MERRY R
IPC: C12N9/06
Filed: 2001-02-07
Granted: 2015-11-17
Abstract: A naturally occurring or recombinant protein, especially a mutein of porcine urate oxidase (uricase), that is essentially free of large aggregates can be rendered substantially non-immunogenic by conjugation with a sufficiently small number of strands of polymer such that the bioactivity of the protein is essentially retained in the conjugate. Such conjugates are unusually well suited for treatment of chronic conditions because they are less likely to induce the formation of antibodies and/or accelerated clearance than are similar conjugates prepared from protein preparations containing traces of large aggregates.

Granted: 2006-08-08
Abstract: A process for forming a rod of bioabsorbable polymeric material includes extruding the material at a temperature above its melting point at a controlled rate of between 4 to 20 feet per minute to form a continuous rod (12). The continuous rod (12) is then cooled by passing the rod through a cooling bath to cause nucleation.  The continuous rod (12) is passed through a first puller (28) running at least at the same speed as the extruder. A second puller (30) is provided which is moving faster than the first puller (28) so that the continuous rod is elongated at a ration of between 2 and 12 times. During this elongation, the rod (12) is heated to a temperature of between 55 °C and 140 °C in an oven located between the first and second pullers. The rod (12) is annealed at a temperature of between 70 °C and 110 °C after being elongated but prior to exiting the second puller (30). Upon exiting the second puller (30), the tension in the rod (12) is released and the continuous rod is then allowed to cool. A cutting station (50) is then provided to cut the continuous rod into desired lengths.
