Patent CA-2048764-C (CA)
Title: Fuel injector nozzle support
Inventor: ROBERTS HUBERT SMITH JR
IPC: F23R3/28
Filed: 1991-08-08
Granted: 2003-01-07
Abstract: A fuel injector nozzle support includes a support plate joinable to a combustor dome and a ferrule slidably joined to the support plate. The ferrule includes a base, and a bore for slidably receiving a fuel injector nozzle.     The ferrule base has a noncircular perimeter and the support plate includes a receptacle for receiving the ferrule base which has an inner circumference being complementary to the ferrule base perimeter for presenting rotation of the ferrule base greater than a predetermined maximum rotation while allowing radial translation of the ferrule base for accommodating differential radial thermal movement of the fuel injector nozzle and the support plate. In an exemplary embodiment, the base perimeter and the receptacle have complementary straight and arcuate profiles, and the support plate is formed with counterrotational swirler vanes of a swirler fixedly supported to a combustor dome. The noncircular perimeter assembly eliminates the use of conventional antirotational lugs and stops.

Title: Address protection circuit
Inventor: BRANT WILLIAM ALEXANDER
IPC: G06F21/62
Filed: 1991-10-18
Granted: 2004-02-24
Abstract: An Address Protection Circuit (APC) for cross-checking the integrity of requests to read or write an addressable system memory in a fault-tolerant computer system. in the check mode, the APC checks each address and the source identification code of each memory access request from an address source. The source identication and current bus address are compared to a range of addresses stored in the APC. If the current bus address is within an "authorized" range, access to that range of locations in the memory is allowed to the address source. If a current memory access request is not authorized, the APC asserts an error signal, which may be used to transfer control to a redundant subsys-tem. The APC contains a content-addressable memory element that can be initialized by the subsystem processor with address ranges and type of access allowed for each source. In the setup mode, the APC is first addressed to switch the APC from its check mode to its setup mode. Thereafter, a single value in the APC tables can be changed by the processor. The APC then automatically reverts to its check mode.

Title: Optical coupler/splitter with a filter
Inventor: YANAGAWA HISAHARU
IPC: G02B6/122
Filed: 1992-06-02
Granted: 2001-10-23
Abstract: An optical coupler/splitter having an optical waveguide on the side of light incidence, two optical waveguides on the branched side, branched from the former optical waveguide and each having straight and curved sections, and a dielectric multi-layer film filter provided in a manner crossing the latter waveguides and common to them. The filter is so formed as to intersect with a straight section of one waveguide and with a curved section of the other, so that respective crossing angles between the filter and the branched optical waveguides differ from each other, thereby providing different reflection or transmission characteristics with respect to the branched optical waveguides. An optical signal having a variable wavelength and issued from a measuring apparatus based on the backscattering method is distinguished by the common filter of the coupler/splitter, making it possible to perform measurement of the losses of the branched optical waveguides independently without being affected by interference light. There is no need to provide a plurality of filters having different characteristics, and thus the coupler/splitter has a simplified structure and excellent productivity.

Title: Switch lockouts
Inventor: TUREK MARK E
IPC: H01H9/28
Filed: 1992-11-16
Granted: 1996-02-20
Abstract: Switch lockouts are disclosed which may be fixed to a single toggle switch, a ganged toggle switch, or a similarly acting switch, valve operator, or similar structure to prevent the switch from being operated.  The lockout comprises a projection and abutments which engage the switch handle and the body of the switch.  The projection extends into an aperture of the handle in one embodiment, or under the crossbar of a ganged handle in another.  The abutments, and in some instances the projection, embrace the handle and prevent substantial rotation of the handle with respect to the lockout, or of the lockout with respect to the switch body.  Thus, the switch handle, switch body, and lockout are fixed substantially immovably together.

Title: Tow valve and interlock for a vehicle
Inventor: ZAUN RICHARD DAVID
IPC: B60D1/26
Filed: 1993-05-28
Granted: 1996-07-09
Abstract: A bypass and switch arrangement is connected to the conventional steering system on a towable vehicle.  A rotary bypass valve includes two ports connected between the two hydraulic lines leading from the steering control valve to the steering cylinder or motor.  The bypass valve has a normal operating position which blocks flow between the lines so that normal steering operation is provided.  When the vehicle is connected for towing, the bypass valve is rotated to an open towing position to permit free flow of fluid between the ports and lines so that fluid may move freely to and from the steering motor or cylinder.  If a steering cylinder is used, a third port on the valve is connected to the oil cooler on the vehicle and opens the lines to reservoir through the cooler to accommodate the deficient or excess flow from or to the cylinder which results from the difference in effective area on opposite sides of the ram.  A switch connected between the switched power supply and an electric shut-off valve on the vehicle engine injector pump is responsive to movement of the valve for disabling the engine when the valve is in the towing position.  Before the engine can be restarted after towing, the valve must first be moved back to the operating position wherein normal steering and pump operation is enabled.
