Patent CA-2212942-C (CA)
Title: Gas actuated slide valve in a screw compressor
Inventor: ANDERSEN GARRY E
IPC: F25B31/00
Filed: 1995-12-06
Granted: 2001-02-06
Abstract: The position of a slide valve in a screw compressor in a refrigeration system is controlled using a gaseous medium sourced from the higher pressure of two or more sources of such fluid. Preferred sources are refrigerant gas in a closed compression pocket in the working chamber of the compressor and refrigerant gas in the discharge passage downstream of the compressor's discharge port. The multiple sources of such gas are connected to a solenoid valve which, when open, permits gas to act on the piston which controls the position of the slide valve. Due to a check valve arrangement, it is always the one of the sources of gas which is at higher pressure that acts on the slide valve actuating piston. The adverse affects of refrigerant gas outgassing and gas bubble collapse associated with use of hydraulic fluid rather than a gaseous medium to modulate compressor capacity are avoided while advantageous use is made of compressor overcompression in the control of slide valve position.

Abstract: A method of reinforcing or retrofitting building roof structures against hurricane-force winds which does not require removal of part or all of the roof. The improved method includes directing a thin stream of a liquid polymer foam adhesive under pressure upwardly along the intersections of the rafters or support members and the roof panels, preferably on both sides of the support members. The foam adhesive then creams and foams, forming polymer foam adhesive gussets which firmly adhere to the adjacent surfaces of the support members and roof panels. This method increases the pull-off strength of a roof about seven fold and is able to withstand hurricane-force winds.

Abstract: A video signal receiver with reduced sensitivity to interference from co-channel digital TV signals includes circuitry for selecting a vestigial sideband amplitude-modulation signal descriptive of a video signal, converting the selected VSB AM signal to an intermediate frequency signal, and amplifying the IF signal to provide an amplified IF signal. The VSB AM signal is selected from any single one of a plurality of channels which can contain co-channel interference from a digital television signal. The amplified IF signal is synchronously detected with respect to video carrier frequency for generating an in-phase synchronous detection response and for generating a quadrature-phase synchronous detection response. All frequency components of the quadrature-phase synchronous detection response above a prescribed frequency are phase shifted substantially 90° and are linearly combined with in-phase synchronous detection response for recovering lower frequency portions of the video signal, substantially free of artifacts from any co-channel interfering digital television signal. In some embodiments of the video signal receiver higher frequency portions of the video signal described in the full sideband of the VSB AM signal, but not in its vestigial sideband, are recovered by synchronously detecting the VSB AM signal after selective filtering to remove the pilot carrier signal component of any co-channel digital TV signal. The selective filtering avoids any artifact of such pilot carrier signal being generated when recovering higher frequency portions of the video signal. The lower and the higher frequency portions of the video signal are combined to obtain a fullband video signal.

Title: Base station transmission power control system, mobile station and base station
Inventor: FURUKAWA HIROSHI
IPC: H04B7/005
Filed: 1999-02-15
Granted: 2003-08-05
Abstract: In soft hand over in a code division multi access mobile radio communication system, interference in a down link caused by transmission from a plurality of base stations for one mobile station, can be restricted. Control of transmission power is performed according to command from the mobile station only in the base station serving as a primary base station which has minimum propagation loss with the mobile station during soft hand over, and the base stations other than the primary base station perform transmission with restricting output. In comparison with the transmission power control performed by the conventional plural base station transmission, interference for the peripheral mobile station can be reduced to achieve higher down link capacity. Also, upon restricting transmission power of the base station other than the base stations having small propagation loss with the mobile station among base station group in soft hand over, by moderately attenuating the transmission power instead of restricting abruptly, degradation of the reception quality can be prevented when error is caused in selection of the base station.

Title: Ultrasonic dissection and coagulation system
Inventor: TOVEY H JONATHAN

Granted: 2006-06-13
Abstract: An ultrasonic dissection and coagulation system for surgical use is provided.  The system includes an ultrasonic instrument, a control module, and a handle actuator. The ultrasonic actuator has a housing and an elongated body portion extending from the housing. An ultrasonic transducer supported within the housing is operatively connected to a cutting blade by a vibration coupler. The vibration coupler conducts high frequency vibration from the ultrasonic transducer to the cutting blade. The cutting blade has a cutting surface which is angled with respect to the longitudinal axis of the elongated body portion and, thus, with respect to the axis of vibration. A clamp member having a tissue contact surface is positioned adjacent to the blade member and is movable from an open position in which the tissue contact surface is spaced from the cutting surface to a clamped position in which the tissue contact surface is in close juxtaposed alignment with the cutting surface to clamp tissue therebetween. The clamp member and the angled blade combine to enhance contact between tissue and the cutting surface of the blade member.

Title: Apparatus and method for microwave curing of resins in engineered wood products
Inventor: HARRIS GEORGE M
IPC: B27N3/20
Filed: 1997-10-24
Granted: 2004-12-14
Abstract: An apparatus, system, and method, for using circular mode magnetic microwave energy to heat the interior regions of a work piece (12) of wood fiber and glue. The microwaves are generated and transmitted by a microwave system (38, 40, 54 and 56) as rectangular waveguide mode microwave energy, and are converted by mode converter to circular magnetic mode microwave energy. As circular magnetic mode microwave energy, the microwave energy passes through a work piece or billet (12) of material, is reflected on the other side and travels through the billet (12) a second time. Reflected microwave energy from the main reflected wave as well as reflections from other structures, surfaces and layers in the system travel back toward the microwave source (38). They are sensed at sensor sections (104), and a computer tuning system (144) causes capacitive probes to generate offsetting microwave reflections, which are opposite in phase and equal in magnitude to the sum of all of the reflected waves. These induced reflections cancel and negate the reflected microwaves, resulting in optimum utilization of microwave energy to heat the wood in the billet (12).

Title: Ribosome complexes as selection particles for in vitro display and evolution of proteins
Inventor: TAUSSIG MICHAEL JOHN
IPC: C12P19/34
Filed: 1998-05-28
Granted: 2011-08-09
Abstract: The invention provides a method of diplaying nascent proteins or peptides as complexes with eukaryotic ribosomes and the mRNA encoding the protein or peptide following transcription and translation in vitro, of further selecting complexes carrying a particular nascent protein or peptide by means of binding to a ligand, antigen or antibody, and of subsequently recovering the genetic information encoding the protein or peptide from the selected ribosome complex by reverse transcription and polymerase chain reaction (RT-PCR). The RT-PCR  recovery step is carried out directly on the intact ribosome complex, without prior dissociation to release the mRNA, thus contributing to maximal efficiency and sensitivity. The steps of display, selection and recovery can be repeated in consecutive cycles. The method is exemplified using single-chain antibody constructs as antibody-ribosome-mRNA complexes (ARMs).
