Patent CA-2085202-C (CA)
Title: Positive temperature coefficient start winding protection
Inventor: BUNCH RICKY L
IPC: H02K11/00
Filed: 1992-12-11
Granted: 1996-10-22
Abstract: A protection circuit for a permanent split capacitor motor includes a positive temperature coefficient (PTC) resistor in series with the auxiliary winding of the motor for protecting the auxiliary winding during normal operation.  At a predetermined temperature anomaly due to over-current conditions in the windings, the PTC resistor will sharply increase its resistance to a point wherein no current will pass, effectively open circuiting the auxiliary winding from the power source, thereby protecting the windings from damage.  A thermally responsive protector may also be used in conjunction with the PTC resistor for providing further over-current protection to both the main and auxiliary windings.

Title: Electrode and method for measuring levelling power
Inventor: BLECHTA VLADIMIR KRISTOFUS
IPC: G01N27/42
Filed: 1993-01-19
Granted: 1996-11-26
Abstract: The invention provides an apparatus and method for determining levelling power of an electrolyte. An anode and cathode are immersed in the electrolyte. The cathode has a plating surface for electrodeposition of a metal from the electrolyte. The plating surface has a peak region and a base region separated and electrically isolated by an insulator. The peak region has a greater tendency to electrodeposit the metal per unit surface area than the base region. The anode and cathode are placed in a test cell or suspended in a commercial electrodeposition cell. A means for applying current between said anode and said cathode is used for causing the metal from the electrolyte to electrodeposit on the plating surface of the cathode. The current from plating on the peak region and the base region are measured separately to determine levelling power of an electrolyte.

Title: Hand trucks with pivotally connected, spreadable, wheel-supported, auxiliary support frames
Inventor: MORTENSON CARL N
IPC: B62B1/00
Filed: 1993-02-17
Granted: 1999-10-26
Abstract: A hand truck with an upright main frame and a handle part at its upper end has a forwardly extending nose at its lower end for supporting a load thereon which rests back against the main frame when the main frame is in vertically rearwardly tilted position, and a wheel and axle assembly at its lower end to support it for travel. An auxiliary support frame, having a ground engaging wheel at its lower end is pivotally connected near its upper end to the main frame for movement from the main frame to a spread position. A rearwardly extendible first link structure, pivotally connected to the main frame, is hingedly connected to a second link structure, pivotally connected to the auxiliary frame. Force exerting, compressible spring mechanism, connected pivotally to one of the link structures and to one of the main frame and attachment frame, exerts a moment arm force moving the link structures through an in-line position to lacked over-center position when the auxiliary frame is spread, and positively resists inadvertent movement of the link structures out of looked position, while positively forcing the link structures and auxiliary frame to folded position once the link structures have been moved back from over-center position and through the in-line position.

Patent CA-2104425-C (CA)

Granted: 1998-08-25
Abstract: To allow compact design of a wiper system equipped with a wiping angle varying assembly which comprises an actuating motor, an eccentric cam member provided in a path of transmitting the movement of the output end of a wiper motor to a wiper arm, and a control unit for activating the actuating motor so as to move the eccentric cam member and thereby change the range of angle of the wiping movement by altering a configuration of a linkage structure provided between the wiper motor and the wiper arm, the control unit is adapted to activate the eccentric cam member with such a timing that the force transmitted through the linkage structure from the wiper motor to the wiper arm tends to assist the force produced by the actuating motor to move the eccentric cam member in the required direction.  Thus, the requirement of the power output of the actuating motor can be reduced, and the actuating motor can be substantially reduced in size. As a result, the design of the wiping angle varying assembly is simplified, and the assembly may be conveniently incorporated in a linkage structure similar in structure to the conventional linkage structure for wiper systems not equipped with any wiping angle varying assembly.

Granted: 1996-12-03
Abstract: A method and apparatus for establishing a fluid plug within a well bore which can then be substantially destroyed upon demand to permit reestablishment of the well within a short period of time thereafter. Increased pressure actuates a plug rupture mechanism which destroys the integrity of the plug and allows the plug to be substantially eliminated from the wellbore within a short period of time thereafter. In described preferred embodiments, the plug is comprised of a salt and sand mixture which is highly resistant to fluid compressive forces but is subject to destruction under shear tension forces. The plug may be encased within a plug sleeve which is, in turn, encased within a plug housing which may be disposed within the well bore. The sleeve is associated within the housing so that fluid may be displaced about the plug sleeve as the housing is disposed into the well bore. When the plug has reached the proper position within the well bore, the plug sleeve may be set within the housing such that fluid flow is stopped. A shear member is contained within the plug sleeve and detachably connected thereto. When required, the shear member may be released from the surrounding plug sleeve and forced against the plug to substantially destroy the integrity of the plug through introduction of shear tension forces within the plug structure and reestablish fluid flow through the housing. The plug is further dissolved into well bore fluids to substantially destroy it.

Abstract: The invention provides a new method for casting alloys containing a finely divided phase. A bath of the molten metal having a melting point is provided. A finely divided solid metal having a melting point greater than the melting point of molten metal is introduced into the molten metal. The finely divided metal is reacted with the molten metal to form a solid phase within the molten metal. The molten bath is then mixed to distribute the solid phase withinthe molten metal. The molten alloy is then cast into a solid object containing the solid phase. The solid phase is insoluble in the matrix and has a size related to the initial size of the finely divided solid. The alloy of the invention advantageously consists essentially of, by weight percent, about 3 to 40 aluminum, about 0.8 to 25 nickel, about 0 to 12 copper and balance zinc and incidental impurities. The alloy has a zinc-containing matrix with nickel-containing aluminides distributed throughout the matrix.
