Patent CA-2278437-A1 (CA)
Inventor: TAYLOR STEVEN C
IPC: B60T7/12
Filed: 1999-07-22
Abstract: An emergency brake lock assembly that locks an emergency brake actuator in an engaged position to prevent the vehicle from moving while a lift assembly contained on the vehicle is being operated. The emergency brake lock assembly includes an emergency brake switch that is positioned to detect movement of the emergency brake actuator between an engaged position and a disengaged position. When the emergency brake actuator is in the engaged position, the emergency brake switch generates a brake engaged signal. An auxiliary door switch is positioned to detect the movement of an auxiliary door contained on the vehicle. When the auxiliary door opens, the auxiliary door switch generates a door open signal. Upon receiving both the door open signal and the brake engaged signal, a solenoid actuator moves a locking member to a locked position to retain the emergency brake actuator in the engaged position. The lift assembly positioned in the auxiliary door is energized only when the auxiliary door is open and the emergency brake actuator is locked in the engaged position, preventing the vehicle from moving during lift operations.

Title: Production of iron ore pellets
Inventor: KIGUCHI JYUNPEI
IPC: C22B1/243
Filed: 1999-08-30
Abstract: A process for producing fired pellets by granulating finely-ground iron ore and subjecting the resulting granules sequentially to drying, dehydration, preheating, and firing, wherein said process comprises adding an additive to said finely-ground iron ore at the time of granulation, said additive reacting with iron ore to form a compound which has a melting point lower than the preheating temperature. Owing to the additive (or sintering auxiliary) added in a small amount to iron ore powder, it is possible to produce preheated pellets by using the existing grate kiln without increasing the amount of preheating energy. The resulting preheated pellets have improved strength and produce no adverse effect on finished pellets.

Patent CA-2283046-A1 (CA)
Title: Methodology for emulation of multi-threaded processes in a single-threaded operating system
Inventor: FORSMAN STEPHANIE M
IPC: G06F9/48
Filed: 1999-09-23
Abstract: To emulate multi-threaded processing in an operating system supporting only single-threaded processes and single-level interrupts, the processor timer is started with a selected time-out period during execution of a master code thread. Processing of the master code thread proceeds until the timer interrupt, at which time the operating system timer interrupt service routine (ISR) transfers execution control to a slave code thread or slave code thread component. The slave code thread or component is executed in its entirety, at which time the timer is reset and execution control is returned to the master code thread, where processing resumes at the point during which the timer interrupt was asserted. To minimize disruption of the master code thread execution, a maximum latency should be enforced on the slave code thread, which may be accomplished by breaking the slave code thread into multiple components. The timer ISR maintains an index of the predetermined starting points within the slave code thread(s) with a pointer identifying the next slave code thread component to be selected when the timer interrupt is asserted. Processing thus alternates between the master code thread and the slave code thread or components, with different slave code thread components being selected in round-robin fashion. The duty cycle between the master code thread and the slave code thread or components may be varied by selection of the time-out period and the maximum latency allowed to slave code thread processing.

Title: Method and apparatus for lapping of workpieces
Inventor: MALKIN DANIEL D
IPC: B24B37/08
Filed: 1999-11-05
Abstract: A lapping assembly for lapping a group of workpieces including a pair of lapping discs and a cassette for positioning the workpieces between the lapping discs. The lapping discs are provided with two-component translational oscillations at the appropriate cutting speed, parallel to their working planes. This motion is effected using crank pins rotating about a coaxially positioned axis and elastic members (or swivel-supporting) members coupled to the body of the lapping machine to prevent the lapping discs from rotating. The cassette has an opening having a curvilinear shape for holding the workpieces, and protrusions which extend into the opening. The cassette is mounted on a support element and equipped with a drive to rotate it about a stationary axis. Alternatively, the cassette can be fixed during treatment and the lapping discs can be rotated at a speed less than the cutting speed. The combination of the curvilinear shape of the opening, the oscillations provided to the cassette and the relative rotation of the cassette in relation to the lapping discs cause workpieces to circulate within opening in a pseudo-random manner. The apparatus may also be adapted to finish workpieces to differing heights through the use of a sensor coupled to one lapping disc to detect the pre-set proximity of the other lapping disc.

IPC: G06Q30/02
Filed: 1999-11-08
Abstract: The present invention provides an apparatus and process for facilitating customer-driven sales of products having multiple configurations, preferably automobiles and trucks. The apparatus is a computer network comprising a server with a product database thereon, an intermediary subsystem, and a seller subsystem. The server, intermediary subsystem, and seller subsystem function together and communicate with each other to allow an intermediary, on behalf of a customer, to configure a feasible product, transmit a request for quote (RFQ) to a target set of sellers in the customer's geographic area, receive quotes from the target sellers in response to the RFQ, and transmit the customer's acceptance of one of the quotes to the appropriate seller. The apparatus may also include a customer subsystem by which the customer may configure their own feasible product and transmit their feasible product information to the intermediary. The intermediary subsystem can optionally include a product database thereon which the intermediary can use to configure a feasible product without communicating with the server.  The process allows an intermediary to configure a feasible product, transmit a request for quote (RFQ) to a target set of sellers in the customer's geographic area, receive quotes from the target sellers in response to the RFQ, and transmit the customer's acceptance of one of the quotes to the appropriate seller.
