Patent CA-2178006-A1 (CA)
Inventor: FRASER MICHAEL JAMES
IPC: B23P6/00
Filed: 1994-12-01
Abstract: A method of repairing a turbine blade in which damaged material around a lacing wire hole is removed by machining or chemical etching. New metal is then added by welding such that the lacing wire hole is much smaller or completely eliminated and prior to re-forming the lacing wire hole, flats may be formed either by the addition or removal of metal in the region of the lacing wine hole so that a lacing wire hole forming drill or machine bit can enter the turbine blade at a surface substantially normal to its direction of travel, thereby minimising any tendency of the lacing wire hole forming drill or machine bit to snatch or for the blade to vibrate.

Patent CA-2185170-A1 (CA)
Title: Retrievable well packer
Inventor: HENDRICKSON JAMES D
IPC: E21B33/12
Filed: 1993-05-12
Abstract: A retrievable packer for service at high temperatures and pressures has sealing provided by a seal element prop surface (56) of larger diameter than the seal element support surface (48) of a body mandrel (34).  At least one element (30A) of a seal assembly (30) is supported on the prop surface and is subjected to a radial squeeze in the set configuration, even though a lowermost seal element (30C) may be subject to longitudinal separation.  The split level support arrangement provides an annular pocket (62) into which the elements can be retracted upon release of the packer, thereby providing clearance for retrieval.  In releasing the packer, a retainer collar (68) is shifted away from a metal backup shoe (64), thereby providing an annular pocket into which the shoe is deflected, so that it does not obstruct the drift clearance during retrieval. The seal element assembly is preloaded by a cover sleeve (50) which releases when a predetermined compression has been achieved.  The controlled preloading of the seal elements assists movement of the elements to the larger diameter prop surface, and the seal elements are forced to expand into the annulus uniformly to prevent the formation of uneven extrusion gaps.

Title: Portable self-contained cooler/freezer
Inventor: ANDREWS RUSSELL
IPC: F25D29/00
Filed: 1995-04-03
Abstract: A transportable container (500) for carrying refrigerated products in frozen subzero Fahrenheit (below -18 ~C) or refrigerated (for example, 40 ~F (4 ~C) temperatures) includes a structural container (512) having an insulated outer shell with an access doorway (521). The upper portion of the container (500) includes a tray or drawer in which are disposed a pair of spaced apart canisters containing liquid refrigerant (CO2, for example). A gas or liquid feeder tube penetrates each bottle and communicates with an on/off valve. A  feeder tube can draw liquid to dispense for cooling, or it can release gas and pressure within the canister to boil the CO2. When CO2 reaches its boiling point, the canister, its brackets, and the cold plate reach very cold temperatures to cool the cargo area through conduction. The gas is released through an injection nozzle into the cargo holding area.

Patent CA-2196480-A1 (CA)
Title: Soft decision decoder
Inventor: IGARASHI HIDEKI
IPC: H04L27/22
Filed: 1997-01-31
Abstract: A soft decision decoder including an adaptive equalizer and a reliability information generator. The reliability information generator, receiving soft decision data and equalized square error from the adaptive filter, performs delay detection of the soft decision data, and then rotates the phase of the delay detected data so as to match the data to transmitted data components.  The rotated data is weighted with the average value of the equalized square error to generate the reliability information for the soft decision Viterbi decoding.  This makes it possible to obviate the exponential or logarithm calculations which are conventionally needed for generating the reliability information for carrying out the soft decision Viterbi decoding of the output of the adaptive equalizer, and hence to reduce the enormous amount of calculations and the size of hardware like DSP for performing the calculations.

Title: Multiprocessor system bus protocol for optimized accessing of interleaved storage modules
Inventor: BENNETT BRIAN R
IPC: G06F13/42
Filed: 1995-08-25
Abstract: A multiprocessor information processing system (100) has a system bus (110) with interleaved memory modules (130, 135) in communication with multiple CPUs (120, 125). The multiprocessor system includes a subsystem monitoring circuit which monitors the addresses requested by the local CPU. If the local CPU  addresses a memory module which is different from the last accessed memory module, then the subsystem monitoring circuit initiates a request to maintain control of the system bus. In this manner, sequential write and read operations are typically made to interleaved memory modules so that the effects of module recovery time are minimized. The subsystem monitoring circuit includes a transfer count register which indicates how many data transfer cycles can be run in succession before the local CPU has to relinquish control of the system bus. In this manner, fair arbitration is assured for other CPUs contending for control of the system bus.

Title: Anisotropic reinforced ribbon-cast blanket for extended nip press
Inventor: MCCARTEN PAUL
IPC: D21F3/02
Filed: 1997-08-05
Abstract: A conventional blanket material, preferably a woven fabric or scrim, is formed into a loop of the desired dimensions and impregnated and coated with a two-component urethane resin. As the urethane is applied to the woven substrate, short fibers are introduced into the urethane through a nozzle which aligns the fibers to run in the cross-machine direction. The fibers are introduced in sufficient quantities to provide significant structural reinforcement of the urethane in the cross-machine direction. The coated blanket is then ground to a desired constant thickness and an array of parallel grooves running in the machine direction are milled into the urethane coating. The anisotropic fiber reinforcement provides sufficient modulus to the urethane system to prevent the grooves from collapsing under the applied loads of the extended nip press. The reinforcing fibers may be glass, carbon fiber, synthetic polymer or other structural fiber material.

Title: An apparatus and method for calibrating manifolded tanks
Inventor: MALININ LEONID M
IPC: G01F1/00
Filed: 1996-05-30
Abstract: An apparatus and method are provided for calibrating manifolded liquid storage tanks. The apparatus includes sensors disposed within the tanks for sensing the liquid levels in each of the tanks and a metering device for measuring the amount of liquid dispensed into or out of the storage tanks. A processor is also provided which determines the amount of liquid dispensed from each tank based on liquid level measurements obtained during idle periods following dispensing periods. Once this information is obtained, single tank calibration techniques are employed. An alternate combined tank calibration can also be used. This method does not separate out the amount of liquid dispensed from each tank, but rather utilizes the combined amount dispensed. From this simpler, but less accurate method, an "equivalent" combined tank chart or combined mathematical formula may be generated using the metered amounts and a combined height amount. Heights from the two tanks may be simply averaged. The processor may be programmed to perform either or both methods.
