Patent CA-2044569-C (CA)
Title: Stepper motor throttle controller
Inventor: CHURCHILL JONATHAN D
IPC: F02D31/00
Filed: 1991-06-13
Granted: 1998-07-07
Abstract: A throttle controller for an internal combustion engine employs a stepper motor to move the throttle valve and provides a controller to permit the use of the stepper motor.  The stepper motor requires no return spring or position sensor and hence offer weight and cost advantages.          The throttle position is deduced by means of an up-down counter tracking movement of the stepper motor during throttle control.  The controller includes an integration means to accommodate the unknown starting throttle position.  A fuel cutoff solenoid is activated in the event of over-speed or power loss.  An engine speed signal for the controller is produced by a variable reluctance sensor providing a signal to a slope detector circuit to eliminate the influence of external magnetic fields.

Granted: 1995-02-14
Abstract: The flap (2) of the bottom envelope (3) of a stack (1) is opened with a rotating opener claw (5, 6, 7 ). As soon as the flap is sufficiently open, it is seized by two rotating transport elements (8, 9) and pressed against two conveyor rollers (10, 11).  The opener claws (5, 6, 7) and the conveyor elements (8, 9) are disposed on the same shaft (4), but are supported and driven independently of each other.  The opener claws are only operated from a coupling (12) when a packing operation is to be carried out.  The conveyor elements (8, 9) and the conveyor rollers (10, 11) run continuously.  Two pairs of conveyor rollers (17, 18, 19, 20) convey the envelope towards a packing trap (13).  As soon as the flap (2) of the envelope (3) is positioned below a holding down roller (21), the latter begins to descend.  Simultaneously, the packing trap (13) begins to pivot towards the envelope.  Whilst the envelope (3) is drawn onto the packing trap (13), the prepared contents (38) of the envelope is conveyed by transport fingers (34) into the packing trap (13) from the opposite side.  Transport fingers (34) push the envelope (3) and contents (38) from the packing trap between conveyor belts (43, 44) and out of the enveloping unit.

Patent CA-2081615-C (CA)
Inventor: GABLE DON HENRY
IPC: A47B96/20
Filed: 1992-10-28
Granted: 1996-01-30
Abstract: An appliance cabinet such as a refrigerator cabinet is formed of sheet steel which is textured by coining along one surface and provides a substantially smooth surface on the opposite  side.   The coining operation results  in shallow,  projecting irregularities on the substantially smooth side of the sheet steel.  Non-textured cabinets are formed by bending and joining the sheet steel to form a cabinet shell having the textured side of the sheet steel on the inside and a substantially smooth surface of the sheet steel on the outside.  When a finished paint coating is applied to the substantially smooth side, a leather-like surface appearance results.  When the sheet steel is bent and formed into a shell for a cabinet with the textured side on the outside,  a textured cabinet results.   By forming both types of cabinets from the same sheet steel, manufacturing savings result because only one type of sheet steel must be procured and inventoried.

Granted: 2004-01-20
Abstract: A system for managing resolvers of test answers to maintain consistent and efficient scoring of test answers. Collaborative scoring allows two test resolvers to score the same test answer and resolves potential discrepancies in the scores provided by the resolvers. Quality items monitor a test resolver's scoring performance against a known standard. The system transmits a quality-control test item, having a known score, to a test resolver. After receiving a score from the resolver, the system compares the known score with the resolver's score and can generate a quality profile for the resolver.
