Patent CA-2056578-C (CA)
Title: Food refrigeration system and method incorporating a cryogenic heat transfer apparatus and method
Inventor: LEE RON C
IPC: F25D9/00
Filed: 1991-11-28
Granted: 1998-03-31
Abstract: The present  invention provides a food processing system and  method  for  refrigerating  articles  of  food.   The  food processing system includes at least two cooling stages formed by a cryogenic freezer and a hydrocooler.   The cryogenic freezer receives  the  articles  of  food  and  transfers  heat  from the articles of food to the cryogen so that the articles of food are refrigerated.  After the transfer of heat from the articles of food to the cryogen,  the cryogen boils off to form cryogenic vapor.  The hydrocooler  receives the articles of food prior to the cryogenic freezer and transfers heat from the articles of food to supplied cooling water.  Such heat transfer reduces the quantity of  cryogen  required to  refrigerate  the  articles  of food.  Additionally, an eductor is connected to a pump and to vent  line from the cryogenic  freezer.   The cooling water  is pumped through the eductor to suction cryogenic vapor from the cryogenic freezer and to mix the cryogenic vapor and the cooling water prior  to  reception  of  the  cooling  water  in  the hydrocooler.  Such mixing transfers heat from the cooling water to the cryogenic vapor to increase the heat transfer between the articles and the cooling water in the hydrocooler.  As a result of such increased heat transfer, the amount of cryogen required in refrigerating the articles is further reduced.   The eductor and pump combination has general application to the cooling of articles.

Title: Semipermeable membrane cartridge and method of making
Inventor: ROBBINS ADAM
IPC: B29C67/24
Filed: 1992-08-03
Granted: 1996-10-01
Abstract: Cartridges for use in ultrafiltration or reverse osmosis separation devices are formed by injection molding a generally tubular, smooth, seamless shell about a spirally-wrapped semipermeable membrane assembly. These cartridges can be used within traditional separation devices having pressure vessels of precise interior diameter, for which the cartridges are uniquely suited because they have cylindrical surfaces of true circular cross-section and close tolerances.  The cartridges can also be created so as to incorporate integral pressure vessels and thus permit their use in separation processes without the need for surrounding supporting pressure vessels.  A reaction injection molding process is shown which provides for substantial efficiencies in the overall manufacturing of semipermeable membrane separation cartridges of the spirally-wound variety.

Granted: 2007-04-03
Abstract: The invention relates to transgenic non-human animals capable of producing heterologous antibodies, i.e.: antibodies encoded by immunoglobulin heavy and light chain genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, transgenes encoding unrearranged heterologous human immunoglobulin heat and light chains are introduced into a non-human animal thereby forming a transgenic animal capable of producing antibodies encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized; e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody. The invention also relates to heavy and light chain immunoglobulin transgenes for making such transgenic non-human animals as well as methods and vectors for disrupting endogenous immunoglobulin loci in the transgenic animal. The invention also includes methods to generate a synthetic immunoglobulin variable region gene segment repertoire used in transgene construction and methods to induce heterologous antibody production using animals containing heterologous rearranged or unrearranged heavy and light chain immunoglobulin transgenes.

IPC: A61M1/30
Filed: 1991-06-26
Granted: 1998-07-14
Abstract: A simplified fluid separation method and device usable for various apheresis procedures, including plasmapheresis.  At least one pump is utilized to draw a first fluid (e.g. whole blood) into a separation device.  The separation device then operates to separate the fluid (e.g. whole blood) into first and second fluid fractions (e.g. a cell concentrate and blood plasma).  The first and second fluid fractions are pumped from the separation device to separation first and second fluid fraction containers, both of which are positioned on a single weighing device, such as an electronic load cell.  At least one of the fluid fractions is subsequently removed from its fluid fraction container and returned to the human subject or other fluid source.  Weights recorded by the single weighing device are then utilized to calculate the actual weights of fluid and/or fluid fractions pumped by at least one pump during the procedure.  Such actual weights of fluid and/or fluid fractions are then utilized to calculate new pump flow constants, thereby enabling the calibration of the pump(s) to be corrected, on the basis of such new pump flow constants, prior to subsequent utilization of the pump(s) for pumping the fluid and/or fluid fractions.  The single weighing device may also be utilized to monitor the weight change or rate of weight change occurring as the fluid fractions are pumped into and/or out of the fluid fraction containers, thereby providing a means for monitoring and verifying the pressures and flow rates within the system.
