Inventor: RAJOTTE RAY V
IPC: A01N1/02
Filed: 1995-03-31
Abstract: A method for bulk cryopreservation of biological material includes the steps of providing a flexible container, such as a freezer bag, containing biological material that is treated with a cryoprotectant and freezing the biological material to below -100 °C and preferably below -196 °C for deep freeze long-term storage.  In the preferred embodiment, the bag is placed in a holder that maintains the cross-sectional area of the bag essentially constant and small enough (e.g., about 5mm width to facilitate uniform heat transfer to and from all regions the bag.  This facilitates uniform nucleation of the biological material after supercooling which enables controlled and uniform slow cooling through from about -7.5 °C to a temperature in the range of about -40 °C to -80 °C, thereby maintaining the viability of the cells. The single freezer bag method facilitates cryopreservation of large amounts of material, such as entire preparations of isolated islets, as compared to conventional multiple tube cryopreservation protocols and yields similar or improved recovery.  In addition, the single freezer bag method reduces the risk of cross-contamination, a problem when adding and withdrawing material form multiple tubes before, during and after the cryopreservation freeze-thaw cycle.  The bag construction also reduces the risk of freezing medium (e.g., liquid nitrogen) seeping into the bag and causing the bag to burst when thawing the material.  The present invention also provides for encapsulation of the biological material before cryopreserving, whereby the material is encapsulated in a gel, such as alginate.  Further provided are methods for stabilizing the material for shipment, storage in culture, and transplantation through the use of encapsulation.  Encapsulation of the material also improves or helps retain its viability over unencapsulated material.

Title: Integrity confirmation of evaporative emission control system against leakage
Inventor: COOK JOHN E
IPC: F02M25/08
Filed: 1993-12-01
Abstract: An on-board diagnostic system for an evaporative emission control system (10) of as internal combustion engine (12) powered vehicle employs a positive displacement reciprocating pump (24) to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump (24) is powered by using engine intake manifold vacuum to force as intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in as air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak is the evaporative emission space. Detection of this rate serves as a measurement of leakage for he purpose of distinguishing integrity of the evaporative emission space from non-integrity.

IPC: A61P9/00
Filed: 1994-03-08
Abstract: The present invention is directed to a method for preventing or reducing ischemia following injury, such as reperfusion injury following ischemia, cellular damage associated with ischemic episodes, such as infarctions or traumatic injuries, and thus to prevent or reduce the consequent progressive necrosis of tissue associated with such ischemia.
