Patent CA-2350055-A1 (CA)
Inventor: BORZA STEPHEN J
IPC: G06K9/00
Filed: 2001-06-07
Abstract: The invention relates to a pore imaging system and method. According to the method, a template is formed using a high-quality imager for imaging a pore image. A lower-quality imager is used to capture pore image data for registration against the template in order to authorise or identify individuals. The lower-quality imager provides less information than the high-quality imager. For example, the lower-quality imager may have a lower resolution per unit area, a smaller image area, or both. A system for implementing the method is also disclosed.

Abstract: A collapsible container for storing and transporting a liquid comprises a mainly retangular base section (1), two opposite end sections (2; 3) and two opposite side sections (4; 5 - VEL IKKE 3; 4) pivotally connected to each their respective side of the four sides of the base section (1), a top section (6) pivotally connected to a side section (4; 5) or an end section (2; 3), and a liner (51) for storing the liquid. The sections (2, 3, 4, 5, 6) are arranged to pivot in relation to each other between a first position in which they in rows are extending mainly parallel across each other and a second position in which they jointly are defining a chamber for containing the liner (51). The collapsible container has locking means (32; 35) for in second position locking the end sections (2; 3) and the side sections (4; 5) together in such a way that they in this position only can be pivoted in over the base section (1). One of the end sections is furthermore constructed as a door section (3) partly consisting of a frame (40) connected pivotally about a swivelling axis to the base section (1), partly at least one door (39) connected pivotally about a second swivelling axis to the frame (40). This structure is well suited for resisting the pressure acting from within of the liquid in a full liner (51). An assembler can furthermore easily gain access to conveniently mount the liner (51) via the door (39) which opens outwards in a way that is charateristic of the invention.

Abstract: The invention relates to a method for controlling the process during rough grinding of a workpiece (2) in which, according to the invention, the workpiece (2) is measured during grinding by a sensor (13) to ascertain an actual size, and the measured actual size is corrected in a continuously automatic manner to attain a predetermined specified size according to grinding time. The invention also relates to a grinding machine which is provided for carrying out the method and which comprises a grinding wheel (10) for rough grinding a workpiece (2) on a grinding spindle head.  The grinding machine also has a sensor (13) for detecting a ground workpiece dimension, and comprises a machine control, whereby the workpiece (2) is held between a workpiece spindle (1A) and a tail spindle (4A). According to the invention, the sensor (13) is arranged primarily in a plane formed by the contact area of the grinding wheel (10) which turns on the workpiece (2), and during rough grinding, said sensor continuously transmits measurement signals to the machine control. Said machine control controls the grinding wheel (10) based on these signals in such a way that the grinding process can be executed as an in-process control.

Title: Thermosiphonic oil cooler for refrigeration chiller
Inventor: LARSON JAMES W
IPC: F25B1/00
Filed: 2000-01-27
Abstract: Oil cooling is accomplished in a refrigeration chiller by flowing hot oil into heat exchange contact with liquid refrigerant which is sourced from the chiller's condenser (14) and returned thereto. The rejection of heat from the oil to the refrigerant in an oil-cooling heat exchanger (36) causes vaporization of the refrigerant and, in turn, creates a density difference in the refrigerant flowing from the condenser (14) and refrigerant in and downstream of the oil-cooling heat exchanger (36). This density difference is responsible for inducing and maintaining refrigerant flow through the heat exchanger (36) for oil cooling purposes.

Patent CA-2382442-A1 (CA)
Inventor: PATEL RAJESH S
IPC: A61M15/00
Filed: 2000-09-11
Abstract: A nozzle (38) comprising a thin, flexible substantially planar polymeric film (46) having a plurality of pores (302) with structures allowing for generation of an aerosol at reduced extrusion pressure is disclosed. The pores can comprise at least two sections, or steps (h1, h2), in which the thickness of the membrane is reduced in stepwise fashion, or the pores can be tapered.  Nozzles formed comprising pores having such structures permit aerosol generation at lower extrusion pressures, thereby allowing for decreased weight of aerosolization devices, increased efficiency, increased portability and increased battery life. The pore structures (302) also allow for the use of thicker, more easily processed polymeric films in manufacturing while having a thinner, more efficient aerosolization area. The use of decreased extrusion pressures also results in increased uniformity in aerosol generation and improved reliability of other components.

Patent CA-2386971-A1 (CA)
Inventor: MOERKE BENJAMIN H
IPC: F16B21/06
Filed: 2002-05-21
Abstract: The fastener includes a pin and a body. The pin includes longitudinal grooves which communicate with partially threaded grooves which traverse the circumference of the shank by an integer multiple of 180°. Retention fingers engage the longitudinal grooves in the pre-installed configuration and allow straight-line insertion of the pin into the body. The retention fingers are then urged outwardly by the walls of the partially threaded grooves and then snap engage into subsequent portions of the partially threaded grooves thereby preventing straight-line removal of the pin. The pin, however, can be subsequently removed by threaded rotating the pin until the retention fingers engage the longitudinal grooves. Thereafter, the pin can be manually removed by a straight-line motion.

Abstract: The mechanism of hypertension following acute NO synthase blockade is via endothelin-mediated vasoconstriction. Thus, NO appears to inhibit endothelin activity by blocking its expression and not as a chronic direct acting vasodilator.  Administration of an endothelin antagonist to a patient in a 'normal' physiological state may result in specific regional vasodilation. This treatment finds utility in the treatment of erectile dysfunction.
