Patent CA-2139189-A1 (CA)
Title: Surface Protective Films
Inventor: KOGA HITOSHI
IPC: C09J7/02
Filed: 1994-12-28
Abstract: The underside of a base layer consisting of one or more sub-layers is overlaid with an adhesive layer that is chiefly composed of an .alpha.-olefin copolymer that is based on at least two .alpha.-olefins selected from among .alpha.-olefins having 2-12 carbon atoms and which has a crystallinity of up to 10%, and said adhesive layer will develop an initial tack of at least 20 g/25 mm when attached to the surface of a stainless steel plate at 23°C.  The thus produced surface protective film, when attached to various kinds of adherends, will not experience separation of the adhesive layer from the base layer while developing strong initial tack, will experience only small changes in adhesive strength (peel strength) with the lapse of time after attachment to the adherends, is sufficiently low in blocking force to provide ease in film handling during the rewinding operation and it yet can be manufactured at low cost.
Patent CA-2140963-A1 (CA)
Inventor: VARGA GABRIEL
IPC: G09G5/393
Filed: 1995-01-24
Abstract: A memory address pointer that selects a memory location that is mapped to a video graphics circuit port is incremented only when all bytes in a memory location have been read from or written to by the host CPU.  This does not depend on the order in which the host CPU reads or writes data bytes.  Therefore a video controller that uses the present invention will work with 8 bit, 16 bit as well as high performance 32 bit input/output instructions.

The other polyol is prepared by (1) admixing ethylene carbonate and one or more hydroxyl functional compounds under reaction conditions sufficient to react the ethylene carbonate and the hydroxyl functional compounds to produce a polyol precursor, and (2) admixing the polyol precursor with diethylene glycol and an anhydride, a dicarboxylic acid, a tricarboxylic acid or mixtures thereof, optionally in the presence of a catalyst.
Patent CA-2148177-A1 (CA)
Title: Method and apparatus for stretching bitmaps to non-integer multiples
Inventor: BIGGS KENT E
IPC: G06T3/00
Filed: 1995-04-28
Abstract: The stretching of bitmap images in a computer system is accomplished by stretching each row of a source bitmap and storing the pixel information associated with the stretched row in a buffer, typically in main memory.  The pixel information is transferred multiple times to the memory location associated with the destination bitmap, these memory locations generally reside in either main memory or in the frame buffer.  Each time the buffer is written to the destination bitmap, an error term is adjusted by a predetermined amount.  When the value of the error term meets a predefined criteria, the next row of the source bitmap is stretched and stored in the buffer and the process is repeated.

Patent CA-2151841-A1 (CA)
Title: Fluid injector
Inventor: NEUMANN BARRY RICHARD
IPC: F02M51/08
Filed: 1993-12-21
Abstract: A gas injector for a gas fuelled internal combustion engine.  The gas injector comprises a valve member adapted to seat against a valve seat in a first or closed position, in which a flow of gas through the injector is prevented, and being movable to a second or open position in which the valve member is lifted from the valve seat to permit a flow of  gas  through  the  injector. The  injector  further comprises a solenoid actuator for moving the valve member from the first to the second position responsive to an electrical control signal.   In use,  by modulating the electrical control signal a precisely controlled quantity of gas can be delivered by the gas injector to the internal combustion engine.  The valve member has a conical valve face and a hollow elongate valve stem having a first opening at one end and a second opening in the form of three radial apertures at the other end to allow a flow of gas through the valve member in use.   The valve stem is provided with an annular flange at one end, which faces the end face of the solenoid actuator.  The annular flange is of magnetic material and forms the armature of the magnetic circuit formed by the solenoid actuator.  Outer casing of the injector is manufactured of magnetic material, and a wall of the outer casing is located immediately adjacent a coil so that,  in use,  together with a core member and annular flange, it forms part of the magnetic circuit of the injector.  Careful design of the mechanical structure and magnetic circuit reduces flux leakage and minimizes the total air gap to provide a rapid response time for the injector.

Patent CA-2172774-A1 (CA)
Title: Active power management for a computer system
Inventor: EBRAHIM ZAHIR
IPC: G06F15/177
Filed: 1996-03-27
Abstract: The present invention provides a method and apparatus for actively managing the overall power consumption of a computer network which includes a plurality of computer systems inter-connected to each other. In turn, each computer system has one or more modules. Each computer system of the computer network is capable of independently initiating a transition into a power-conserving mode, i.e., a "sleep" state, while keeping its network interface "alive" and fully opera-tional. Subsequently, each computer system can independently transition back into a fully opera-tional state, i.e., an "awake" state, when triggered by either a deterministic or an asynchronous event. As a result, the sleep states of the computer systems are transparent to the computer network. Deterministic events are events triggered internally by a computer system, e.g., an internal timer waking the computer system up at midnight to perform housekeeping chores such as daily tape backups. Conversely, the source of asynchronous events are external in nature and include input/ output (I/O) activity. The illusion of the entire network being always fully operational is possible because the system controllers, the interconnects and network interfaces of each computer system remain fully operational while the selected modules and peripheral devices are powered down. As a result, each computer system is able to rapidly wake up from the sleep state in response to stimuli by powering down selected modules thereby accomplishing power conservation without requiring a static shutdown of the computer network, i.e., without affecting the overall performance and response of the computer network.

Patent CA-2179713-A1 (CA)
Inventor: LE BOUDEC JEAN-YVES
IPC: H04L45/122
Filed: 1993-12-24
Abstract: This invention defines a routing method which allows to determine best paths from link weights in situations where these weights are not additive, but the characteristic of a concatenated path is determined mainly by single "bottleneck" links. To be compatible, the metric must be chosen from a specific set of metrics, called bottleneck metrics in this description. The new widest-path method has some characteristics in common with the known Dijkstra method for additive weights. Implementations in communication networks are disclosed which lead to new nodes, new networks and new network protocols. The widest-path method, however, can solve many other routing problems not necessarily related to electronic communication.
