Patent CA-2095133-A1 (CA)
Title: Gerotor pumps
Inventor: HODGE STEVE
IPC: F04C2/10
Filed: 1991-10-22
Abstract: A gerotor pump comprises the usual lobed annulus (30) containing the lobed rotor (not shown in figure 2) which is journalled on cylindrical boss (36). The boss is free to turn on the eccentric pin (38) between positions controlled by limit pin (42) encountering end abutments. This enables the pump to automatically adjust to the variable direction of drive of the annulus -in this case via coupling (32)- so as to be unidirectional in fluid output via flow passages (16, 18).

Title: Time metered response airbag inflator
Inventor: MARCHANT BRENT R
IPC: B60R21/26
Filed: 1993-05-05
Abstract: ABSTRACT    An air bag inflator responds to signals from a diagnostic unit to terminate filling of the bag prior to full inflation.          This is accomplished by a piston propelled by a secondary charge which is ignited by a second signal from the diagnostic unit.          The piston blocks the air bag inflation passages and simultaneously opens vents to discharge the remaining inflation gas.

Patent CA-2097716-A1 (CA)
Inventor: TONELLI FERNANDO A
IPC: B01D17/02
Filed: 1992-10-09
Abstract: A system is provided to treat wastewater from a metal-working facility, such as an automotive manufacturing plant in a bioreactor using live microorganisms. Such wastewater contains waste fluids which are a mixture of relatively easily biodegradable fats and oils, much less easily biodegradable synthetic fluids, oils and greases, and non-biodegradable material including inorganic finely divided solids such as metal and silicon carbide particles. Such waste fluids require a hydraulic retention time (HRT) and a solids retention time (SRT) which is 10 times greater than for sewage. High quality water is separated from suspended solids which are removed from the reactor at an essentially constant rate and fed to an ultrafiltration membrane. Concentrate is recycled to the reactor, except for a bleed stream to remove solids periodically.  The membranes acquire a long and effective life despite large variations in membrane flux, because of a permeate recycle which permits operation of the bioreactor at constant volume; permits flow of feed wastewater to the reactor at constant flow rate; and allows operation of the membrane modules at a relatively low pressure in a narrow range which does not damage the membranes. Such operation of the bioreactor allows one to use a reactor which is one-half the size (volume) than one which would be required with a system without a permeate recycle. Effective and long-lived operation of the membranes is obtained by filtering out (through a 140 mesh screen) all solids greater in diameter than about 106 µm. Pilot plant tests conducted with wastewater from automobile manufacturing plants over a period of more than a year provide evidence of the surprising effectiveness of the system over a prolonged period.

Title: Safety penetrating instrument
Inventor: YOON INBAE
IPC: A61B17/34
Filed: 1991-12-18
Abstract: The safety penetrating instrument (30) includes a tubular needle (32) having a distal end with a sharp tip (46), a safety probe (34) movable within the needle between an extended position protecting the needle tip and a retracted position exposing the needle tip and is biased toward the extended position and a portal sleeve surrounding the needle to establish communication with an anatomical cavity with penetration of tissue surrounding the cavity by the needle. The needle distal end has a leading edge defining the sharp tip and a trailing edge and the portal sleeve has a distal edge disposed in substantial alignment with or forward of the trailing edge of the needle distal end. A locking mechanism automatically locks the safety probe in the extended position after the safety probe is returned thereto or can optionally allow locking of the safety probe or allow proximal movement of the safety probe after return to the extended position. The locking mechanism also provides selective locking of the safety probe in the retracted position.

Title: Apparatus and Technique for Fluid Level Determination in Automatic Transmissions
Inventor: NIEMCZYK ROBERT T
IPC: B60W50/02
Filed: 1993-06-30
Abstract: An apparatus and technique for fluid level determination in automatic transmissions.  The invention employs an electronic control unit in association with an automatic transmission for a vehicle, the electronic control unit receiving data corresponding to transmission oil level, transmission oil temperature, engine speed, transmission speed, and transmission selected range.  Upon determining that such data satisfies certain diagnostic tests, the level of transmission fluid within the transmission is determined and adjusted or otherwise normalized to ideal test conditions.  The electronic control unit compensates an oil level signal for deviations in oil temperature from an optimum test temperature, and makes further compensation for deviations in engine speed and settling time at the time that the test data is acquired.  Additionally, variations in oil density as a function of oil temperature are also compensated.

Patent CA-2105155-A1 (CA)
Inventor: THIBAULT JEAN-GUY
IPC: F28F13/08
Filed: 1993-08-30
Abstract: PRÉCIS: Dans l'industrie automobile, l'organe principal du système de refroidissement des moteurs de véhicules est le radiateur. Il permet l'écoulement d'un fluide à l'intérieur de faisceaux linéaires, de sections uniformes, longs et minces, dont la paroi extérieure est munie d'ailettes. Lorsque le radiateur est soumis à une ventilation forcée, le transfert de chaleur se fait entre les ailettes du radiateur et l'air ambiant. Dans la présente invention, on utilise des faisceaux munis de chambres de relaxation réparties uniformément tout au long du faisceau. La présence de chambres de relaxation dans les faisceaux est nécessaire et améliore, considérablement sur plusieurs points le rendement thermique des radiateurs. Premièrement, les chambres de relaxation ont pour effet d'augmenter la surface extérieure des faisceaux (celle en contact avec l'air), offrant ainsi une surface de transfert de chaleur plus importante avec l'air ambiant et ce, en utilisant qu'un seul pont thermique, soit la paroi séparant le fluide chaud et l'air ambiant. Deuxièmement, ces chambres de relaxation permettent une augmentation du volume de fluide à l'intérieur des faisceaux à être exposé à l'air ambiant, tout en gardant le fluide chaud près de la paroi, par conséquent, permet le refroidissement d'un volume de fluide plus important. Troisièmement, lorsque le fluide chaud pénètre une chambre de relaxation, celle-ci engendre, dû à la vitesse de fluide chaud, une zone de turbulence permettant au fluide chaud de s'agiter contre les parois de faisceaux et des chambre de relaxation. Cela permet au fluide chaud de se refroidir uniformément à l'intérieur des faisceaux. Ce type de radiateur offre d'autres avantages, tel l'élimination d'ailettes entre les faisceaux lorsque celui-ci est soumis à une ventilation forcée, un entretien simplifié dû aux arêtes arrondis des chambres de relaxation éliminant le phénomène "piège à mouches", une économie de surface effective de transfert due au positionnement en diagonal des chambres de relaxation.

Title: Resurfacing of rodent antibodies
Inventor: PEDERSEN JAN T
IPC: G01N33/531
Filed: 1993-09-07
Abstract: The present invention relates to the development of prediction rules that can be used to accurately model the variable regions of antibodies. A statistical analysis is presented which is based on accessibility calculated for a range of antibody crystal structures. When this information is applied to an antibody sequence database, it is possible to discriminate between human and murine antibodies at the sequence level purely on the basis of their surface residue profiles. A humanized rodent antibody that gives the appearance of a human antibody is predicted by substituting the set of surface exposed amino acid residues from the rodent antibody or fragment thereof with the set of surface exposed amino acid residues from the human antibody. A three dimensional model can then be constructed from the resulting, fully substituted variable region of the rodent antibody or fragment thereof.

Filed: 1994-01-31
Abstract: Apparatus for detecting or measuring movements in geological and other formations and capable of carrying out such measurements on a three-dimensional basis. The apparatus has a housing acting as a support and an elongated arm, e.g., a stiff measuring rod of adjustable length, projecting from the housing and acting as a movement following element. One end of the rod is secured within the housing by sliding and pivoting connections so that the remote end of the rod may move freely in three dimensions relative to the housing. Three movement sensors are positioned within the housing. A first one of the sensors measures translational motion of the rod in the axial direction. A second sensor measures rotation of the rod about the pivot in a first plane. A third sensor measures rotation of the rod about the pivot in a second plane which intersects the first plane at right angles. The first movement sensor is preferably a linear potentiometer and the second and third sensors are preferably rotary potentiometers. The signals from the sensors may be subjected to mathematical transformations for conversion to spatial positions of the remote end of the rod, making it possible to detect and measure three-dimensional ground displacements.
