Patent CA-2157264-A1 (CA)
Inventor: PETERSON JOHN P
IPC: H05K3/34
Filed: 1995-08-30
Abstract: Fluxing and soldering terminals on a printed circuit board by an in-line process in which flux concentration is determined at specific locations laterally of the passline.  At each of the positions infrared light is passed through a wall of flux which is being directed at the board.  The infrared light becomes partly absorbed by materials in the flux and the unabsorbed light which passes through the wall of flux is used to generate signals corresponding to the different wavelengths of unabsorbed light at each of the locations.  This enables a determination to be made of the flux concentration at each location.  The signals are preferably used to effect a change in the flow rate of flux at any specific location so as to control the amount of flux deposited upon the board. Particularly useful for "no-clean" flux applications.

Title: Methods and compositions for controlling plant development
Inventor: NEILL JOHN D
IPC: C12N15/82
Filed: 1994-03-09
Abstract: A family of genes has been found in plants, said genes encoding a family of developmental proteins that have homologous structures to the mammalian QM genes. A QM promoter and anther specific promoters have been isolated. Recombinant molecules which include the QM genes in plants are useful to transform cells and regenerate plants that, as a result, have altered developmental pathways. Methods of producing male sterile plants use recombinant molecules containing either the QM sense genes or antisense genes with appropriate promoters.

Patent CA-2167791-A1 (CA)
Title: Method and apparatus for preventing inadvertent changes to system-critical files in a computing system
Inventor: CARLEY WILLIAM J
IPC: G06F21/00
Filed: 1996-01-22
Abstract: System-critical files are protected from being inadvertently modified or deleted by placing them in a Reserve name space of storage that requires any process seeking modifying access to the Reserve name space to have a "Right" to do so.  The right to modifying access is garnered by a process first making a call to a system library procedure that causes a memory-stored data structure associated with the calling process to be modified, identifying the process as one with a Right to make modifying access to the Reserve name space.  Any attempt to modify, delete, or create any file residing in the Reserve name space without the Right will be refused.

Title: Dump/stop valve for surface controller subsurface safety valve
Inventor: JOHNSON CLARENCE WILLIAM
IPC: E21B34/10
Filed: 1996-03-22
Abstract: A dump/stop valve used to close and open a surface controlled subsurface safety valve (SCSSV) and a surface safety valve (SSV).  The dump/stop valve permits the SSV to close prior to the closure of the SCSSV to avoid wear and possible damage to the SCSSV.  Likewise, the dump/stop valve permits the SCSSV to be opened prior to the SSV for the same reasons.  A time delay is built into the dump/stop valve operation to provide for a predetermined time period between the closing of the SCSSV and closing of the stop valve to ensure all fluid is exhausted.  The stop valve ensures that downhole fluid does not leak into the reservoir.

Title: Force generation system
Inventor: HALL BART
IPC: F41A33/00
Filed: 1996-04-09
Abstract: A system for exerting a force, for instance a vertical upward lifting force of a predetermined tension vs. time waveform on a suspended object is useful in training the operators of shoulder-supported rocket launchers. The system includes an actuator for generating a required tensile force, a non-stretchable line or cable for connecting the object to the actuator and an overhead guide supported on an overhead support structure. The cable passes over the guide means defining a portion of the cable directly supporting the object. The position of the guide is controlled, in a response to a deviation from verticality of the portion of the cable with suspended object, before the activation of the actuator so that the verticality of the object lifting force is maintained. In operation, a predetermined force is exerted on the object regardless of whether the object moves as a result of the force.

Title: Method, Instrument and Anastomotic Fitting for Use When Performing an End-to-Side Anastomosis
Inventor: RYGAARD JORGEN A
IPC: A61B17/00
Filed: 1994-04-12
Abstract: An end-to-side anastomosis between a first vessel (27) and a second vessel (51) is carried out using an anastomosis instrument comprising a tube (20) in which the first vessel (27) is inserted and everted at the end of the tube (20) to form a collar (28) a springy anastomotic fitting (30) with outwardly directed spikes (32) having previously been placed under elastic bending in a circumferential recess (22). The tube (20) is inserted in a previously made incision in the second vessel (51), a guide member (35) ensuring that the wall region (53) around the incision contacts the everted collar (28). Then, an ejector (23) is operated to liberate the fitting (30) from the recess (22), releasing the fitting to expand quickly, so the spikes (32) penetrate the collar (28) and the wall region (53). Finally, the tube (20) and the ejector (23) are removed, and so is the guide member (35) having previously been made to collapse in a manner not shown to allow it to be removed through the first vessel (27).
