Patent CA-2248216-C (CA)
Inventor: LUPIEN FRANCIS
IPC: H04W60/04
Filed: 1997-02-26
Granted: 2004-11-30
Abstract: In a TDMA or CDMA cellular telephone network (10) including a plurality of registration areas (32), and in instances of mobile station (16) cell reselection between a cell (12) located in a first registration area and a cell located in a second registration area, the mobile station processes control or pilot channel signal strength measurements in view of both a conventional reselection hysteresis (30) and an additional registration hysteresis (36). Reselection is performed by the mobile station when the control or pilot channel signal strength measured (26) with respect to the second registration area cell exceeds the control or pilot channel signal strength measured (24) with respect to the first registration area cell by the sum total of both the reselection hysteresis and the registration hysteresis. This makes it more difficult to obtain an inter-registration area cell reselection to the benefit of minimizing the likelihood of incurring unnecessary consumption of valuable cellular air interface and system resources due to mobile station transit back and forth between the two registration areas.
Patent CA-2249236-C (CA)
Inventor: MCPHEE CHARLES J
IPC: A61M5/142

Granted: 2007-08-07
Abstract: Disclosed is an infusion pump (400, 600) for expelling a fluid from a collapsible fluid reservoir (406, 640) to a patient. The pump (400, 600) includes a housing (401, 601) having a chamber (446, 646) therein for receiving the fluid reservoir (406, 640). A first wall (404, 604) is provided on the housing for contacting the fluid reservoir (406, 640), and a second wall (410, 630) is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall (410, 630) from the first position to the second position expels fluid from the collapsible reservoir (406, 640) at a substantially constant rate by applying increasing force on the fluid reservoir (406, 640) through the dispensation cycle. Preferably, the first and second walls (406, 410, 604, 630) are provided with non-planar complementary surface (408, 413, 415, 417) for contacting the collapsible reservoir (406, 630).

Title: Oil separation and pumping system and apparatus
Inventor: SHAW CHRISTOPHER K
IPC: B01D17/02

Granted: 2005-12-27
Abstract: A system for separating fluids of differing densities includes a pair of pumps interconnected to and driven by a motor positioned therebetween. The pumps each have intake ends, distal second ends, and a pump intake proximal the intake end. The pumps, the motor, and a production tubing form a production string. A shroud is sealably connected to the production string at one end of the shroud at a position intermediate the motor and the pump intake of one of the pumps. The shroud surrounds the pump and extends at least partially over the pump. The shroud forms a fluid communication passageway between the pump and the shroud and an orifice at the end of the shroud opposite the sealed end to form an effective pump intake. A  second shroud similar to the first shroud surrounds the other, second pump and is sealably attached to the production string intermediate the motor and the second pump.  The effective pump intakes formed by the shrouds are at least sixty feet from one another.

Title: Ensemble a enroulements segmentes imbriques
Inventor: DOCKSTADER KARL DAVID
IPC: H02K16/02
Filed: 1997-05-19
Granted: 2002-11-05
Abstract: Cette invention concerne un ensemble à enroulements segmentés "SCA" destiné à des dispositifs rotatifs électromoteurs, tels que moteurs et générateurs, qui font usage de multiples enroulements (42, 44, 46) fonctionnant à l'intérieur d'une structure magnétique à entrefer axial. Les enroulements conducteurs individuels possèdent des parties (39) décalées, en saillie par rapport à la circonférence, conçues pour permettre l'imbrication des parties (37) à extension radiale d'enroulements adjacents dans le but de constituer un ensemble circulaire dans lequel tous les conducteurs opérationnels des enroulements, qui sont ceux disposés dans le champ magnétique axial, peuvent être orientés dans un même plan. Cette construction minimise l'écartement de l'entrefer de la structure magnétique, et maximise de ce fait le flux magnétique disponible. L'ensemble SCA résultant peut aisément être transformé en moteur actionneur ou générateur triphasé. L'invention se rapporte également à une structure dans laquelle les ensembles à enroulements multiples et les rotors magnétiques associés peuvent être empilés alternativement en couches de manière à accroître encore plus la zone opérationnelle totale des enroulements à l'intérieur d'un moteur ou d'un générateur de diamètre donné.

Abstract: A self-cleaning lint trap includes an enclosed housing having an inlet port, an exhaust port, and a spiral chamber between the ports for imparting a circular air flow to air moving through the spiral chamber. A fine mesh screen extends across the exhaust port, and along the cylindrical side wall of the spiral chamber, for collecting lint from air passing through the chamber. A freely movable lightweight object is enclosed within the spiral chamber, and is moved about the chamber by the circular air flow to break off lint from the screens. A slot in the side wall of the chamber is fluidly connected to a lint collector, such that the compacted lint ball will be carried from the chamber through the slot and to the lint collector for later disposal.
