Patent CA-2339280-A1 (CA)
Title: Non-planar orbital welder
Inventor: LORINCZ THOMAS A
IPC: B23K9/12
Filed: 1999-08-04
Abstract: An orbital welder includes a weld tip, a rotational controller and a translational controller. The rotational controller causes the weld tip to rotate about an axis passing through the tube to be welded. The translational controller causes the weld tip to move longitudinally with respect to the axis, forming non-planar orbital welds. In one embodiment, the translational controller includes a rotor disposed to rotate about the axis. The translational controller includes a carrier that is slidably attached to the rotor. The weld tip is fixed to the carrier.  The carrier moves longitudinally with respect to the axis such that the weld tip follows a non-planar orbital weld pattern. In a particular embodiment, a portion of the carrier is biased against a surface a cam block. The surface of the cam block is contoured to displace the carrier longitudinally with respect to the axis of rotation.

Filed: 2001-03-12
Abstract: A gear pump comprising a plastic gear pump housing having an interior surface. Rotatably attached to the gear pump housing is a drive gear and an idler gear.  The idler gear is cooperatively engaged to the drive gear such that rotation of the drive gear will rotate the idler gear. The gear pump housing is formed from plastic such that the interior surface thereof is sized to contact the drive gear and the idler gear. Accordingly, the contact between the idler gear and the drive gear with the interior of the plastic gear pump housing forms a seal therebetween which is used for the pumping of fluid by the gear pump.

Title: Soft turn-off controller for switched reluctance machines
Inventor: MORRIS DAVID J
IPC: H02P25/08
Filed: 1999-11-03
Abstract: A circuit for controlling the operation of switched reluctance machines (i.e., motor or generator) having a plurality of phase windings. The circuit slows down the initial "turn off" of the phase windings to eliminate an abrupt reduction in the current flowing therethrough. This reduces the impulse which excites mechanical oscillations in the motor/generator, reduces switching losses in the switching transistors, and reduces the number of harmonics.

Title: Dutch auction system with preregistered bid feature
Inventor: HOGENDOORN PAUL
IPC: G06Q30/08
Filed: 2001-06-18
Abstract: A descending bid auction system includes preregistered bids from remote locations. Preregistered bids submitted before an auction cycle begins are awarded a sale when the pricing device declines to a price that matches that of the preregistered bid. In keeping with traditional Dutch auction style, in one example, local bidders who submit a bid are given priority because of the first-submitted tradition. Similarly, when more than one remotely submitted preregistered bid is for the same price, the first such bid submitted is given priority. An alternative way of using a remote bidding terminal designed according to this invention is to competitively bid while an auction cycle is in process. Bids submitted while the auction cycle is in process preferably are submitted when a remote clock, which operates in advance compared to the auction site clock, reaches a desired price. the remote bid preferably is received at the auction site before the auction site clock reaches the intended price.

Abstract: An upper imperforate cap closes the uppermost end of a bailer and a lower imperforate cap closes the lowermost end of the bailer. In a preferred embodiment, screwthreads are formed in the uppermost and lowermost ends of the bailer and complemental screwthreads are formed in the upper and lower caps. In another embodiment, screwthreads are formed in a downspout and complemental screwthreads are formed in an imperforate downspout cap. By capping the opposite ends of a bailer, the bailer serves as its own container when the sample contained within it is shipped to a laboratory. This eliminates VOC devices, nozzles, and the concomitant contamination that may result from emptying a bailer in the field.
