Patent CA-2246187-C (CA)
Inventor: BUSCHERT KEVIN DONALD
IPC: F16H7/12

Granted: 2004-08-31
Abstract: The drive-chain tensioner is automatically self-adjusting. A chain-slipper is guided to follow wear-movement of the chain. A cam is mounted on the follower. If slack in the chain increases, the cam is rotated by a cam spring to a position in which a larger radius of the cam lies under the follower, The care provides a solid abutment that prevents the chain from compressing the tensioning springs and becoming slack when drive is reversed. For compactness and good load distribution, the chain is supported on a saddle between two cams. The cams have ratchet teeth.

Title: Location system with field actuation sequences
Inventor: ACKER DAVID E
IPC: G01V3/10
Filed: 1997-02-24
Granted: 2004-07-06
Abstract: A method and system of operating a location system to locate objects in spac e, such as medical instruments (16) within the body of a patient is presented. The method includes cyclically actuating transmitters (10a, 10b, 10c) in a fixed frame of reference for the transmission of magnetic fields to a plurality of sensing units (54a, 54b, 54c). The sensing units detect characteristics of the fields during actuation sequences for determining location. At least one transmitter may be actuated during at least some of the cycles in a plural-value actuation sequence to provide a field with different field strengths during a sequence of plural sensing intervals, and with a progressively varying field strength value during transition intervals between the sensing intervals.

Abstract: Provided is a swing-driving device for driving two blow molding units so as to swing around corresponding swinging fulcrums, each of the blow molding units having a carriage, one end portion of which is supported by the swinging fulcrum so as to swing, and a blow molding mold disposed on the carriage.  The blow molding mold of one blow molding unit receives a parison on a common receiving position and is made to be an mold close state.          The blow molding mold swings around a swinging fulcrum, and moves from the receiving position to a shunting position via a detaching position.  Thereafter, the blow molding mold returns to the detaching position and is made to be a mold open state.  A hollow article formed by blow-molding the parison in the blow molding mold is take out and moved to the receiving position kept in the mold open state.  The other blow molding unit swings from another shunting position to another detaching position similarly to the case of said one blow molding unit, immediately after one blow molding unit has moved to the shunting position.

Abstract: A hill-holding arrangement for an electrically driven vehicle includes a vehicle with a "gas pedal" which generates a torque command signal T CMD. A switch (314) couples T CMD to a motor controller (316, 14) which drives the motor (40) and therefore the vehicle. When the "gas pedal" calls for zero torque, and the vehicle speed is zero, the switch responds to logic (FIGURE 5), and substitutes a position-holding torque command signal T.THETA. for the operator-controlled torque command signal T CMD. Position controlling torque command T.THETA. is generated by a controller (312) which receives a position signal representative of the angular position .THETA. of the rotor. The position-holding torque control loop then produces such torque as may be required to prevent the rotor of the motor from moving from its commanded position.

Abstract: A submergible pumping unit for raising viscous fluids from a well is driven by an electronic drive and control system, a first portion of which is located above the well, and a second portion of which is coupled to the submergible pumping unit. The drive and control system includes a power supply circuit located above the well for converting AC power from a source to DC power having current and voltage levels. The DC power is transmitted to the pumping unit via a two-conductor DC bus cable. The pumping unit includes a switching circuit which receives the DC power for driving a submergible motor, such as a permanent magnet brushless motor. The speed of the motor, and of a pump coupled thereto, is proportional to the voltage of the DC power applied to the pumping unit. The pump is preferably a progressive cavity pump, and the drive and control circuitry provides sufficient torque to start the pump from a static condition. A control circuit is provided for transmitting configuration and desired flow rate and speed data to the power supply.

Title: Self-evacuating vacuum cleaner
Inventor: BERFIELD ROBERT C
IPC: A47L7/00
Filed: 1998-01-14
Granted: 2005-04-12
Abstract: A vaccum cleaner has an electric motor driving an air impeller (74) for creating suction and a pump (120) which draws liquid material through an inlet tube (310) from the bottom of a tank (32) and expels it from the tank. The vacuum cleaner also includes a mechanical shut-off and override assembly that automatically shuts off the motor if the liquid level in the tank gets too high. The user, however, can mechanically override this automatic shut-off in order to continue pumping liquid out of the tank. A priming apparatus is disposed in the tank in fluid communication with the pump, and a valve (58) is selectively actuable to establish a pressure differential across liquid in the priming apparatus to thereby prime the pump (120).

Abstract: The invention applies to the structural core of the three-dimensional concrete reinforcing mat consisting of distribution bars and load-bearing bars, where the distribution bars (1) of folded length equal to the width (W) of the mat, are throughout their length bent forming a meander consisting of a continuous row of incomplete equilateral trapezoids with slanted sides (h w), shorter bases (b) and imaginary longer bases (c). The equilateral trapezoids of the distribution bar (1) are laying in the same plane oriented alternately mutually opposite each other so, that slanted sides (h w) of each two opposing each other trapezoid s are of the same length and are identical. The straight load-bearing bars (2) of the structural core's length, are attached to meandrically bent distribution bars (1) into each corner-bend on inner side of their trapezoids. The distribution bars (1) and load-bearing bars (2 ) form together structural mat-core's longitudinal ribs (R) of regularly by 180.degree. alternating trapezoidal cross-sectional form. The m at based on this structural core is designated for its usage primarily as reinforcement of concrete structures and of miscellaneous precast concret e products used in construction of highrises, bridges and/or in underground structures of civil engineering, as well as for military purpose s, security installations and/or temporary structures, where this structural mat's core due to its formed longitudinal load-bearing ribs (R) would serve mainly without its combination with concrete as a steel structure, that is as a finished product.

Abstract: Cette invention se rapporte à des méthodes d'analyse fondées sur la réaction d'un réactif à réponse magnétique soumis à l'influence d'un champ magnétique, qui permettent de mesurer qualitativement ou quantitativement la liaison entre des éléments de paires de liaison spécifiques. Conformément à cette invention, la présence d'un analyte est à l'origine de la liaison ou de la non liaison du réactif à réponse magnétique à un réactif en phase solide, mobile. Le degré de liaison module la réponse du réactif à réponse magnétique ou celle du réactif en phase solide, mobile, ou des deux, à l'influence d'un champ magnétique. De ce fait, la mesure de la réponse au champ magnétique du réactif à réponse magnétique, ou celle du réactif en phase solide, mobile, permet de déterminer avec précision la présence ou la quantité de l'analyte contenu dans un échantillon d'essai. Cette invention fait appel à divers dispositifs pour mettre en oeuvre les méthodes d'analyse décrites ci-dessus.

Granted: 2010-10-05
Abstract: The present invention pertains to an improved nozzle for use in wear-resistant rotary atomizers and to atomizer wheels containing said improved nozzles.   Said atomizer wheels and nozzles have the same wear resistance as the ones described in the prior art or even better, but at the same time, the nozzles have been improved to provide microspherical particles with a very narrow particle size distribution.   The nozzle of the present invention comprises wear-resistant sintered material and has a flow channel in the shape of a vertical slot. Said vertical slot may optionally be uniformly rounded. It was found that when these improved nozzles are used for spray-drying suspensions, microspherical particles with a narrower particle size distribution are obtained than when using nozzles with cylindrical flow channels.
