Patent CA-2216628-A1 (CA)
Title: Closed system for volatile organic compound recycling
Inventor: BUCHHOLZ LORETTA P
IPC: B05B15/12
Filed: 1996-03-28
Abstract: In the method and system of the instant invention, volatile organic compounds (VOCs) liberated in the course of solvent-based painting of a workpiece, are recovered. The atmosphere within a closed spray-booth (10) is maintained at a fixed humidity such that vaporized water, supplied in the form of steam or nebulized water vapor, acts as a carrier for VOCs liberated in the course of spray painting or heat curing of a workpiece. The VOCs may be recovered continuously, including during the spray-painting or heat curing of the workpiece. The VOC laden, humidified air is circulated through a condenser (14) such that VOCs dissolved in the water vapor condense and are directed to a recovery means. The water and solvent are separated, recovered and purified for re-use or placed in an appropriate container (15) for disposal, thereby eliminating the usual practice of expelling VOC laden air into the atmosphere.     The system is provided with a flame-free heat source (17) to cure the painted workpiece and to guard against the danger of explosion.

Title: Waste agent reservoir for suction drainage system
Inventor: MAHER PASCAL JAMES
IPC: A61M1/00
Filed: 1996-03-27
Abstract: A disposable receptacle is connected to a suction system and includes a sealed liner with a lid and a pour spout. A waste treating reservoir includes a closed container with an open mouth for storring a waste treating agent. A  cylindrical wall forms a diffuser cap. A closed end portion has a plurality of apertures opening radially through the cylindrical wall. An open end portion fits telescopically over the open mouth of the agent container. A double-walled sleeve has an inner wall and a generally concentric outer wall for attaching the combined diffuser cap and agent container to the spout of the disposable receptacle lid. The inside surface of the inner wall of the sleeve sealingly covers the radially opening apertures in the diffuser cap when the cap is in a first position relative to the sleeve.  The diffuser cap is slidable to a second position in the double-walled sleeve. At the second position, the radial opening apertures are moved axially beyond the inside surface of the inner wall of the sleeve. This allows an open passageway for the waste treating agent to flow from the reservoir to the chamber of the disposable receptacle. The reservoir is configured so the system can be set up prior to the surgical procedure and can be readily activated immediately after the surgical procedure so that hazardous waste can be treated promptly and efficiently.

Title: Apparatus and method for mitigating excess time delay in a wireless communication system
Inventor: SPEAR STEPHEN L
IPC: H04B7/26
Filed: 1996-12-13
Abstract: A wireless communication system (200, 300, 400, 500) mitigates the effects of excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so that the cumulative time delay at a transition cell (209, 325, 331) is reduced. In another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverage area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Title: Nouveaus facteurs secretes par des micro-organismes gram positifs, genes codant pour ceux-ci et procedes d'utilisation
Inventor: QUAX WILHELMUS JOHANNES
IPC: G02F1/1335
Filed: 1996-07-05
Abstract: La sécrétion de protéines hétérologues par des bactéries Gram positives, en particulier de Bacillus, a rencontré peu de succès, à quelques exceptions près. La raison principale de cet échec réside dans l'incompatibilité de protéines hétérologues avec "l'appareil" de sécrétion des protéines de l'hôte. Ce facteur limitant pour la production de protéines hétérologues par Bacillus subtilis à des concentrations économiquement viables est éliminé par une surexpression de la protéine FtsY de Bacillus subtilis ou une surexpression de cette protéine associée à une surexpression d'autres composants de la particule bactérienne de reconnaissance des signaux. Ce ou ces gènes sont surexprimés dans les cellules hôtes de Bacillus exprimant une protéine hétérolgue, ce qui aboutit à une augmentation de la sécrétion de la protéine hétérologue dans le milieu de culture.

Title: Switch with one-bit resolution
Inventor: KALLIONIEMI TAPIO
IPC: H04Q11/04
Filed: 1996-09-04
Abstract: The invention relates to implementing switching in a switch in a digital telecommunications system. N incoming signals are introduced to the switch, each comprising successive one-bit time slots that form successive frames each comprising K time slots. The contents of the time slots for the incoming signals are stored in a memory at a memory location determined by a write address in such a way that a word having the width of at least one bit is stored at one memory location. One word at a time is read out from the memory, wherefrom the desired bit is selected for the outbound signal from the switch. To optimize the size and power consumption of the switch, the incoming signals are distributed to X multiplexers (A1...A x), each interleaving the incoming signals thereto into a single serial output signal (IN1...INX), and writing into memory is carried out by writing the contents of the time slots of the output signals into the same memory location having a width of at least X bits, the memory location changing from one time slot of the output signals of the multiplexers to another.
