Title: A solid state sensor for carbon monoxide
Inventor: GOSWANI KISHOLOY
IPC: G01N21/78
Filed: 1994-01-21
Abstract: A molybdenum, tungsten or vanadium salt-palladium, ruthenium or osmium salt composition for CO detection is made reversible by addition of ferric, chromium or cerium ion. The system is made more CO specific by adding an interference control salt which forms white or colorless precipitates with interfering species.  The operational and shelf life are extended by a mixture of counterions which prevent reduction of the catalyst; the acetate counterion is particularly useful as a redox property modifier.  In a solid state optical sensor for CO, the chemistry is contained in a polymer embedding matrix, with permeation enhancer, if required.  Solubility of the chemistry in the polymer matrix is enhanced by introducing lipophilic counterions.  The matrix with embedded sensing chemistry is coated on an optical support to form an optical transducer which may be an interference type transducer.

Patent CA-2160057-A1 (CA)
Inventor: AKENO MITSURU
IPC: A44B18/00
Filed: 1995-10-06
Abstract: In a hook structure for a molded surface fastener, in an arbitrary cross section of each of a stem and a hook-shape engaging portion of a hook, the cross-sectional area is divided into front and rear side cross-sectional areas with respect to the center line of the hook, and the front side cross-sectional area is defined to be larger than the rear side cross-sectional area.  Therefore, the neutral plane of the hook is shifted toward the front side of the stem and the inner side of the hook-shape engaging portion to a further extent than conventional to reduce possible tensile stresses in the front part of the stem and the inner part of the hook-shape engaging portion so that, as compared to the conventional hook made of the same resin quantity and having a substantially similar shape, the strength of the hook is increased sharply and, necessarily, both the front part of the stem and the inner part of the hook-shape engaging portion is increased in rigidity as compared to the other part and hence is difficult to deform, thus causing an increased strength as well as an increased engaging strength with a loop of a companion surface fastener.

Patent CA-2177623-A1 (CA)
Inventor: ALEXANDER LLOYD G
IPC: E21B47/06
Filed: 1996-05-29
Abstract: A method is provided for determining the inflow rates of gas and liquid upon completion of an underbalanced well. The casing is placed, blocking fluid communication between the well and the formation. A tubing string is run in, forming an annular space and a tubing bore. The well is conditioned by removing sufficient liquids to create an underbalanced state and leaving a gas-filled space above any residual liquid. The volume of the gas-filled space in the annular space and the tubing bore is determined. The well is perforated, opening communication between the well and the formation. Pressure within the tubing bore and annulus is measured as a function of time.  The rate of change of pressure is dependent upon the nature of the incoming fluid; be it gas or liquid. From the above, the rate of incoming fluid can be established as a function of the volume of the gas-filled space and the rate of change of pressure. The inflow rates of solely gas or solely liquid may be determined whether substantially all the liquid is removed during conditioning or only some of the liquid is removed.

Abstract: An improved guidewire for advancing a catheter within a body lumen which has a high strength proximal portion, a distal portion formed of superelastic alloy and a connector formed of superelastic alloy to provide a torque transmitting coupling between the distal end of the proximal portion and the proximal end of the distal portion. The superelastic alloy elements are preferably cold worked and then heat treated at a temperature well above the austenite-to-martensite transformation temperature, while being subjected to longitudinal stresses equal to about 5 to about 50 % of the room temperature yield stress to impart to the metal a straight "memory". The guiding member using such improved material exhibits a stress induced austenite-to-martensite phase transformation at an exceptionally high constant yield strength of at least 70 ksi for solid members and at least 50 ksi for tubular members with a broad recoverable strain of at least about 4 % during the phase transformation.
Patent CA-2181317-A1 (CA)
Title: Multi-Point Door Lock
Inventor: CHAPUT IVANHOE E
IPC: E05C9/04
Filed: 1996-07-16
Abstract: A door lock has a latch which is rotatable from a retracted position to an extended position by means of a linkage. A safety button extends from the latch when the latch is retracted. The linkage cannot be moved unless the safety button has been pressed, which occurs when the door is adjacent the door frame. This prevents the latch from extending and so damaging the keeper in the door frame. The linkage also has a notch which cooperates with a tang projecting from the housing. The tang an notch prevent the latch from being rotated from the extended position to the retracted position except by operation of the linkage. This feature makes it difficult to force the lock open without a key. In addition, one or more remote locks may be added to the main lock. With two remote locks it is possible to provide three anchor points for a door. Further, the remote locks are individually adjustable so that the reach of the latches can be varied to suit the configuration of the door frame or door, and so to accommodate irregularities due to installation or warpage. One of the remote locks can rotate in the opposite direction from the main lock so that the door cannot be lifted off its track.
