Patent CA-2206649-C (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1997-05-30
Granted: 2000-04-04
Abstract: A cryogenic method and apparatus using a liquefier and a two stage distillation column capable of operating in two modes, namely a first mode of operation during which only liquid nitrogen is produced and a second mode of operation during which liquid nitrogen and liquid oxygen are produced. By adjusting the time of operation in each mode, any ratio of liquid nitrogen to liquid oxygen greater than the ratio achieved during the second mode of operation can be achieved. In the first mode of operation, a condenser is used to condense the lower pressure stage gaseous nitrogen into lower pressure stage nitrogen condensate. To condense the lower pressure stage gaseous nitrogen, either at least a portion of the crude oxygen liquid from the higher pressure stage, at least a portion of the oxygen-enriched liquid from the lower pressure stage, at least a portion of the liquefied air, or mixtures thereof, are introduced to the condenser. In the second mode of operation, the top condenser is not used; instead, all of the crude oxygen liquid is introduced into the lower pressure stage, which produces a bottom liquid oxygen stream and a low pressure overhead waste stream containing nitrogen. The system includes fluid flow lines and valves for directing the flow of certain fluids, particularly the crude oxygen liquid and the oxygen-enriched liquid, during the two modes of operation.

Title: Determination of cpsa
Inventor: ALLARD WILLIAM JEFFREY
IPC: G01N33/573
Filed: 1997-09-03
Granted: 2007-06-19
Abstract: A method for determining the complexed forms of immunologically determinable prostate specific antigen (cPSA) in a blood sample, e.g., by two- site immunometric assays, in which the blood sample is treated to render free PSA (fPSA) immunologically nondetectable. A particularly preferred immunometric assay method employs three anti-PSA antibodies: an antibody that binds to both cPSA and fPSA (anti-tPSA), a second anti-tPSA antibody which is characterized by the unique property that binding to fPSA is blocked by binding of fPSA-specific antibodies, and a third antibody which is a fPSA-specific antibody. Thus, binding of the fPSA-specific antibody to PSA in the sample allows only cPSA to be measured in the immunometric assay. Measurement of cPSA blood levels has been found to provide a method for aiding in the diagnosis and monitoring of prostate cancer that is highly sensitive and specific, and eliminates the need for a significant number of patients to undergo unnecessary prostate biopsy.

Title: Electrothermal chemical cartridge
Inventor: WILKINSON GREGORY MARK
IPC: F42B/
Filed: 1995-03-23
Granted: 2005-03-22
Abstract: An electrothermal chemical cartridge (10) with a fuse (18) of tapering cross section enables higher impulse energy to be imparted to a projectile (6) by means of complete controlled burning of propellant (24). A  long, narrow tube (16) filled with propellant (24) has a fuse (18) on its inside surface with a cross section that tapers toward the discharge end, separated from the electrical ground of the cartridge casing by a layer of insulation sufficiently thin to be destroyed as the fuse ignites the propellant. A high-voltage electrode (26) connected at the back end (14) of the tube (16) provides for application of a pulse of sufficient current density to ohmically heat or burn the fuse in a controlled fashion from the discharge end (12) to the back end (14). Many such tubes (152) can be bundled together in a large casing (150) for wide barrel guns.

Title: Mos charge pump generation and regulation method and apparatus
Inventor: TRAN HIEU VAN
IPC: G11C16/06
Filed: 1997-09-30
Granted: 2001-07-24
Abstract: MOS charge pump generation and regulation method and apparatus of the general type used in a non-volatile memory chip for generating high voltages (~20v).  This invention utilizes a current controlled oscillator to generate the clock for the charge pump voltage multiplier.  The oscillator frequency is designed to compensate for process, temperature and power supply variations.  The charge pump shunt regulator only utilizes regular low voltage NMOS and PMOS from a standard CMOS process.  A reference voltage scheme is used in which a regular low voltage PMOS is used as a mirror diode (reference PMOS) to precisely realize a control voltage for the shunting NMOS without violating any breakdown mechanism, i.e. PMOS gated diode breakdown and P+ to n-well junction breakdown.  A medium voltage level is also used to buffer the shunting NMOS transistors from gated diode breakdown.  A native NMOS cascode current mirror is used to precisely mirror the current to achieve minimum headroom voltage with minimum circuit area.

Abstract: The present invention relates to a seal plate at the platform portion of a gas turbine moving blade.  The seal plate is inserted in a gap between the adjacent platforms at each end portion of a seal pin to prevent air from leaking to the outside.  A groove is provided at each of four corners of the end portion of platform of the moving blade, and the seal plate is inserted to cover the gap so as to extend the end portions of the adjacent platforms, by which the gap between the platforms is blocked.  A seal pin and end seal pins are inserted between the platforms to seal this portion.          However, there is a gap at the end portions, so that cooling air leaks from the lower part of platform.  Since the seal plate is inserted in the groove to block the gap, the sealing property is increased.

Abstract: A mower for harvesting crop includes windrow forming housing where crop is discharged after being cut. A windrow grouper attachment includes a crop conveyor attached to the main frame of the mower by a vertically swingable support which is selectively disposable in a lowered working position where it intercepts crop exiting the windrow forming housing and transfers it side ways and in a raised non-use position wherein it permits crop exiting from the mower to be deposited into a windrow directly behind the mower. The vertically swingable support for the crop conveyor is mounted to a slide that is in turn mounted for shifting laterally on a transverse beam of the mower main frame. By selectively manipulating the conveyor among its working, non-use and shifted positions, it is possible to deposit three windrows alongside each other for being subsequently picked up together for processing by another machine, such as an ensilage harvester, for example.

Inventor: ZEBROSKI HENRY A
IPC: F16H25/20
Filed: 1999-04-15
Granted: 2006-08-29
Abstract: A bi-directional no-back device for a ballscrew rotatable in opposite directions has a ballscrew flange with radial surfaces at opposite sides thereof to receive and transfer a bi-directional axial and torque load from an external source. First and second thrust plates are moveable axially of the ballscrew in a housing to transfer compressive loads exerted on the ballscrew in one direction and tensile loads exerted on the ballscrew in the other direction. This maintains a first set of skewed roller brake rings in tight frictional engagement with the ballscrew flange, a first ratchet wheel and the first thrust plate assembly or a second set of skewed roller brake rings in tight frictional engagement with the ballscrew flange, a second ratchet wheel and the second thrust plate assembly, depending on the direction of the external force applied to the ballscrew. First and second pawl assemblies are mounted on the housing and cooperate with the first and second ratchet wheels to permit freewheeling of the first ratchet wheel in a first direction and freewheeling of the second ratchet wheel in the opposite direction, for controlling the effective brake torque applied by multi-stage brakes.
