Patent CA-2287682-A1 (CA)
Title: High performance fan tail heat exchanger
Inventor: TAVASSOLI BAHMAN
IPC: H01L23/367
Filed: 1999-10-27
Abstract: A novel plate fin heat exchanger adapted for high and low velocity fluid flows for dissipating heat from a heat generating component. The heat exchanger comprises an array of fins being affixed to and in thermal communication with a thermally conductive base, wherein the fins are arranged in a fan tail configuration for minimizing flow bypass, and further providing reduced thermal resistance for fluid passing through the fin field. The fins are affixed to and in thermal communication with the base at an acute angle, such that the effective width of the array of fins exceeds the width of the base. The enlarged effective width of the fin array in comparison to conventional heat exchanger provides an increased volume for fluid flow, thereby allowing a greater volume of fluid to enter the fin field and a greater surface area of plate fins for cooling the fluid passing through the heat exchanger. In addition, the heat exchanger comprises a fin density of at least ten fins per inch or greater of base length thereby providing a narrow channel heat exchanger with a fan tail. The aspect ratio of the individual channels between the fins, as compared to parallel fins affixed perpendicular to the base through an extrusion method, generates a reduced pressure drop across the heat exchanger. Accordingly, the heat exchanger of the present invention expands the envelope of cooling performance provided by fluid flow over an array of thermally conductive plates.

Title: Fluid handler and method of handling a fluid
Inventor: WARNKE KEVIN C
IPC: G01F11/00
Filed: 1998-05-19
Abstract: Methods of fluid handling are disclosed. In one method, a pump fluidly associated with a nozzle is energized to move a first fluid with respect to the nozzle. Pressure fluidly associated with the nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the first fluid. An average of the pressure substantially continuously monitored is calculated. The calculated average is used to determine a threshold. The pump fluidly associated with the nozzle is energized to move a second fluid with respect to the nozzle. Pressure fluidly associated with the nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the second fluid. The substantially continuously monitored pressure is integrated. The threshold is compared with the integrated pressure to determine whether movement of the second fluid was intended or unintended.

Title: The inert gas fire extinguishing system
Inventor: MILLS DONALD HUGH
IPC: A62C3/06
Filed: 2000-04-07
Abstract: This system uses inert gases to smother fires. In the first application, carbon monoxide genertaed by engines mounted on a flat bed truck is refrigerated and then enters a reservoir attached to the entrance to the burning building. The gas may pass through the reservoir to fill the entire building, or it can be directed to a particular part of the building where the fire is located. The gas may also be directed from the reser-voir to exterior fires.      In a second application, compressed and cooled carbon dio-xide is used instead of carbon monoxide and is delivered to the scene of the fire either in a gas tanker truck or in cylinders delivered in a smaller vehicle.      Both of these applications would extinguish an advanced fire faster than water, cause less damage to the building, and require less costly equipment. In addition, they would be more effective than water than dealing with certain types of fires, such as fires fed by volatile fuels, chemical fires and elect-rical fires.      In a third application, to fight forest and. brush fires, carbon monoxide or smoke stack gas is delivered from a press-urized and refrigerated tanker truck to a steel box moving over ground fires and to flames above ground by adjustable tubes.      This would be a valuable addition to water bombers and ground crews with shovels and hoses.

Abstract: Method and apparatus for reducing the viscosity of clogging hydrocarbons in an oil well (58). The apparatus is preferably trailer-mounted for portability. It includes a tube type heat exchanger (30) enabling heated gases to pass within feed water coils (48, 44) to heat the water to a predetermined temperature and at a pressure which prevents any flashing or phase change of the feed water within the heat exchanger (30). From the heat exchanger (30) the heated feed water passes through a conduit (54) which empties into the oil well. The well is open to atmosphere so that the feed water undergoes a phase change or flashing when it is introduced into the oil well. The resulting combined steam and hot water reduce the viscosity of the hydrocarbons sufficiently to facilitate their flow out of the oil well. One embodiment of the heat exchanger (30) includes special coil arrangements to promote heating efficiency.

Abstract: This invention relates to the detection of patients at risk for developing integrin antagonist/agonist mediated disease states. This invention also relates to assays useful for the detection in a patient bodily fluid sample of drug-dependent antibodies (DDABs) that bind to integrins in the presence of an integrin agonist and/or antagonist, and to procedures for identifying integrin antagonists/agonists that are less prone to elicit integrin antagonist/agonist mediated disease states. This invention also relates to procedures which increase the recovery of integrin-directed antibodies in body fluids, resulting in an increased sensitivity and specificity of DDAB detection assays and to procedures for treating blood samples, which dissociate antibodies to GPIIb/IIIa from the platelet surface, thereby increasing the recovery from the platelet supernatant. This invention also relates to the use of different GPIIb/IIIa preparations to identify patients at risk for early-onset thrombocytopenia upon treatment with GPIIb/IIIa antagonist/agonists, thereby increasing the specificity of antibody detection.

Abstract: Known cartridges have a cylindrical container part comprising an outlet nozzle arranged at the front, closed end and a piston inserted into the orifice in the rear end and movable in the longitudinal direction of the cartridge and intended for sealing the interior of the cartridge and ejecting the flowable material. The invention relates to such a piston (6). This is essentially in the form of a cylinder which is closed at one end and whose external diameter is at least as large as the internal diameter of the cylindrical container part. It is thus dimensioned so that, for closing the cartridge, it is pressed with a tight fit into the container part. The cylindrical sidewall (8) of the press piston (6) is in addition provided with at least one bevel (11) starting from the end wall (7), so that, when the piston (6) is pressed into the container part of the cartridge, the at least one bevel (11), together with the cylindrical wall of the container part, briefly forms a passage through which the air displaced by the piston can escape outwards, and that consequently no residual air remains in the cartridge and triggers undesirable hardening of the flowable material inside the container part.
