Title: Sliding window & door security device
Inventor: OGONOSKI ALBIN J
IPC: E05C19/18
Filed: 1995-04-06
Abstract: In a device used to secure sliding windows or doors it is convenient to be able to partly open the window or door and still keep the opening secure from access. In this invention latches are secured to the device so that the original window or door lock may be released and allow one of the windows or door to open to a pre arranged distance denying access while securing the second sliding window from opening. The device provides for an alarm device to be attached to send a signal if the device is moved to the non protection mode. Rotating the moveable member of the device through a 90 degree arc releases both latches freeing one or both sliding units to move. The device may also be used to keep one or both sliding units secured fully closed. A length of unit longer than required is supplied to be cut at location to the appropriate length for the desired protection.

Title: Quick coupling for pressure conduit with controlled disengagement
Inventor: LARBOUISSON PATRICK
IPC: F16L37/42
Filed: 1995-04-20
Abstract: A quick coupling conceived for conduits under pressure comprise a latch which permits the disengagement of a male portion (10) from a female portion (1, 3) in two phases.      During the first phase the male portion (10) retracts a controlled distance from its fully engaged position and arrives in an intermediary position in which the valve (5) of the female portion (1, 3) is closed. It further comprises openings (27, 28, 29) for the escape of the fluid under pressure, which openings are situated downstream from the valve (5) and this openings are opened during the said first phase of disengagement.      In the final phase, the male portion (10) is completely disengaged from the female portion.   The controlled disengagement in two phases is effectuated by the cooperation of a latch comprising two actually distance teeth which are positioned in a manner as to oppose each other with respect to the circumferential surface of the male portion in order to alternatively engage of disengage a projection-groove (14) of the male portion.      The control disengagement in two phases avoids a shock which will otherwise be produced during uncontrolled disengagement of the two portions of a coupling in a circuit under pressure.

Title: High temperature hanging system for fluid solid cyclone/plenum systems
Inventor: SHAW DONALD FRANCIS
IPC: F27B15/00
Filed: 1995-05-26
Abstract: In accordance with the present invention, each of a plurality of cyclones is suspended from the roof of a vessel by means of tubular extensions of their barrels.

Patent CA-2157503-A1 (CA)
Title: Pulsed electrochemical detection using polymer electroactive electrodes
Inventor: RIVIELLO JOHN M
IPC: G01N27/327
Filed: 1994-03-04
Abstract: In a first embodiment, a target analyte in solution is detected by exposing the solution to an electrode that includes a conducting electroactive polymer to which a periodic alternating voltage is coupled. Upon exposure to the analyte, an electrode characteristic is varied, which variation is detected by measuring electrode current as a function of time and as a function of the periodic alternating voltage. The alternating voltage waveform has an oxidizing time period and a reduction time period, which periods and waveform duty cycle may be controlled to enhance electrode sensitivity, selectivity, and to substantially eliminate electrode fouling and data hysteresis.  In a second embodiment, a receptor is bound to the electrode, to which is coupled an alternating voltage waveform that permits a mating target substance to reversibly bind to the receptor such that measurement of electrode current provides a measure of such reversible binding. The second embodiment is especially useful for detecting antibodies, antigens, haptens, DNA, RNA, and enzymes. Either embodiment may be used for detection in flow-through electrochemical cells, flow injection analysis, liquid, and ion chromatography, as well as in capillary electrophoresis.

Title: Abrasion-resistant, aesthetic surface layer laminate
Inventor: O'DELL ROBIN D
IPC: B32B33/00
Filed: 1994-04-05
Abstract: A thick aesthetic laminate surface layer is achieved by using pre-cured particulates of the impregnating resin along with an initial binder material and preferably also abrasion resistant mineral particles. The protective overcoating may be applied in a thick layer to give gouge resistance and a deep look. Because the impregnating resin and the pre-cured particulates have the same index of refraction, the transparency of the coating and the resultant clarity of the underlying decor sheet are excellent.

Title: Protease-treated and purified cellulase compositions and methods for reducing backstaining during enzymatic stonewashing
Inventor: FOODY BRIAN
IPC: D06P5/00
Filed: 1996-05-29
Abstract: During the enzymatic "stone washing" of a denim fabric and/or garments, an undesirable redeposition of blue dye often occurs on the surfaces of the denim. The invention relates to a means of overcoming this problem using an enzyme composition comprised of Trichoderma endoglucanases and Trichoderma cellobiohydrolases that has been partially digested by a protease enzyme to separate its core and binding domains. The use of this composition reduces the redeposition of the blue dye and hence improves the stone washing process relative to using a redepositing or backstaining cellulase.
