Patent CA-2123954-A1 (CA)
Inventor: VAN LEAR JEFFREY D
IPC: H01H3/24
Filed: 1994-05-19
Abstract: A hand held actuator comprises a truncated conical housing wherein the volume of air is pressurized by flexure of a diaphragm. A rib protruding from an outer peripheral margin of the diaphragm is received in a groove of a support plate.      Unwanted flexure of the peripheral margin is prevented by supporting the edges supporting the edges of the diaphragm and the plate is spaced apart grooves formed in the interior wall of the housing. The volume of air pressurized by the operation of the diaphragm is communicated by a duct to a signal switch. In one embodiment the duct is connected in a fluid type manner to the interior of the housing by the tapered sleeve. In another embodiment, the duct is joined to a tube forming an extension in an opening in the support plate forming a diaphragm.

Title: A stabilized pharmaceutical formulation comprising growth hormone and histidine
Inventor: SOERENSEN HANS H
IPC: A61K38/00
Filed: 1992-12-16
Abstract: A pharmaceutical preparation comprising a growth hormone and histidine or a derivative of histidine as additive or buffer-ing substance shows a very high stability against deamidation, oxidation and cleavage of peptide bonds. The stability of the pro-duct allows for the storing and shipment thereof in a lyophilized state or in the form of a dissolved or re-dissolved preparation at ambient temperature. Crystallization of growth hormone in the presence of histidine or a derivative thereof gives rise to a higher yield of crystals having a higher purity than known methods.

Patent CA-2151838-A1 (CA)
Title: Engine control unit
Inventor: NEUMANN BARRY RICHARD
IPC: F02D19/02
Filed: 1993-12-14
Abstract: An engine control unit (ECU) in which each of the following engine operating parameters are detected:  engine speed, throttle position, manifold absolute pressure (MAP), gas  pressure,  gas  temperature,  battery  voltage,  air temperature, engine phase and boost pressure control valve (BPCV)  feedback position.   Each of these parameters is provided as an input in the form of an electrical signal to the ECU controller, for controlling the operation of a gas fuelled internal combustion engine.   The ECU controller typically employs the detected engine speed and throttle position to calculate a percentage full load (PFL) value for the engine.  PFL is a non-dimensional measure of the load or torque produced by or required from the engine. The calculated PFL value can then be employed by the ECU controller to calculate the injector ON time (IOT) for each gas injector in a gas delivery system for the engine. Typically,  the PFL value is employed together with the engine speed to calculate a required manifold absolute pressure (MAP) value.  The calculated value of required MAP may then be employed,  together with the PFL value,  to calculate a percent allowable load (PAL) value.  The PAL value is then employed by the ECU controller to calculate the IOT and spark advance for the engine.  By employing gas injectors and accurately calculating the IOT, the ECU can control the correct amount of gaseous fuel to be injected into each cylinder to achieve optimum engine performance under the full range of engine speed and load conditions.

Patent CA-2160200-A1 (CA)
Title: Easily programmable memory controller which can access different speed memory devices on different cycles
Inventor: STEVENS JEFFREY C
IPC: G06F13/42
Filed: 1995-10-10
Abstract: A memory controller which provides a series of queues between the processor and the PCI bus and the memory system.  Memory coherency is maintained in two different ways.  Before any read operations are accepted from the PCI bus, both of the posting queues must be empty.  A content addressable memory (CAM) is utilized as the PCI to memory queue.  When the processor performs a read request, the CAM is checked to determine if one of the pending write operations in the PCI to memory queue is to the same address as the read operation of the processor.  If so, the read operation is not executed until the PCI memory queue is cleared of the write.  To resolve the problem of aborting a Memory Read Multiple operation, an abort signal from the PCI bus interface is received and as soon thereafter as can be done the read ahead cycle is terminated, even though the read ahead cycle has not fully completed.  The memory controller has improved prediction rules based on whether the cycle is coming from the processor or is coming from the PCI bus to allow more efficient precharging when PCI bus cycles are used.  The memory controller is highly programmable for multiple speeds and types of processors and several speeds of memory devices.  The memory controller includes a plurality of registers that specify number of clock periods for the particular portions of a conventional dynamic random access memory cycle which are used to control state machine operations.
