Title: Regulateur d'injection de carburant
Inventor: KILIZ ROBERT L
IPC: F02D1/18
Filed: 1997-05-13
Abstract: L'invention concerne un régulateur d'injection électronique pour commander l'angle d'injection d'une pompe à carburant. Ce système comprend un manchon d'entrée (12), un tambour de sortie (36), un manchon d'entraînement intermédiaire (30), une plaque d'entraînement (60), une fourche d'entraînement (76), et un moteur pas à pas (90). Un manchon d'entraînement (30) comprend une paire de tiges d'entraînement (32) se projetant dans le sens radial vers l'intérieur et vers l'extérieur, un tambour (36) et un manchon d'entrée (12) qui comprennent tous deux des fentes hélicoïdales (38) et (16) respectivement, dans lesquelles se projettent les tiges (32).

Patent CA-2259700-A1 (CA)
Title: Laser-assisted cutting device
Inventor: WHITTENBURY CLIVE G
IPC: B27L5/00
Filed: 1999-01-20
Abstract: The present invention provides a method and apparatus for cutting wood or other materials by separating the material along a line of controlled failure through the application of mechanical force in combination with laser light to break molecular bonds holding the material together along the line of controlled failure. A preferred embodiment of the cutting apparatus is a generally broad wedge-shaped blade having planar lower and upper surfaces which converge toward each other to terminate along a leading edge. The blade is generally hollow with a cavity for passing optical fibers carrying laser light to a transparent window attached to the leading edge of the blade. Laser light passes through the window and is directed to a line of controlled failure in the material being cut to break the molecular bonds and locally weaken the material.

Patent CA-2268706-A1 (CA)
Inventor: KAMIO JUNICHI
IPC: F28D9/00
Filed: 1997-10-17
Abstract: In the case where a partition for partitioning a combustion gas passage inlet (11) from an air passage outlet (16) is defined by a plate (8) attached by brazing to end faces of a plurality of heat exchanger plates (S1, S2) in a heat exchanger (2), durability of the brazed portions are prevented from being degraded due to a load F acting on the plate (8) by a pressure differential between a combustion gas and air. Thus a joint substrate (26) is attached by brazing to the end faces of the heat exchanger plates (S1, S2) with the front surface of the joint substrate (26) brazed to the rear surface of a joint flange (28), which is formed by bending an end of the plate (8) by right angles, and a joint flange (27) having an L-shaped cross section is attached by brazing to an underside of the plate (8) and the front surface of the joint substrate (26). Accordingly, the joint portions are increased in rigidity to ease stress concentration, thus enhancing durability.

Title: Remotely operated meter disconnect switch
Inventor: GRASS WILLIAM ERNEST
IPC: G01R22/00
Filed: 1999-04-23
Abstract: Multiple pairs of stationary and moveable contacts are toggled simultaneously between an open and closed position to disconnect or connect a meter from or to a line power source, by a reciprocating operator driven by low power clock motor. The operator is connected to the contacts through a series of pivotally coupled toggle links that are spring biased to maintain the contacts in either of two stable states, open or closed. The disconnect switch is housed as a modular unit that is interposed between the meter socket and the meter. The switch is remotely actuated and cycles the motor through a pre-determined number of degrees of rotation sufficient to change the state of the contacts.

Abstract: The invention relates to a method of applying a nailwrap to a human nail. The method includes depositing an effective amount of a polymerization catalyst on the nailwrap, placing the nailwrap on a portion of the nail, and depositing a first layer of a monomer over the nailwrap to simulate a human nail. By depositing the polymerization catalyst on the nailwrap, polymerization of the monomer occurs from the bulk, i.e., the surface of the human nail, and proceeds to the surface of the artificial nail structure. The invention also relates to a nailwrap for use on a human nail with a monomer to support an artificial nail structure. The nailwrap includes a woven fiber and an effective amount of a polymerization catalyst embedded in the fiber to substantially polymerize the monomer.
