Patent CA-2065546-A1 (CA)
Inventor: HARDISON LESLIE C
IPC: B01D53/14
Filed: 1992-04-07
Abstract: A method and apparatus including a reaction chamber interposed in a polyvalent metal redox solution flow path between an absorber chamber and an oxygenation chamber, including one or more oxygenation stages, for contact in the reaction chamber of H2S-laden catalytic polyvalent metal redox solution form the absorber chamber with highly oxidized polyvalent metal redox solution from the last oxygenation stage to accomplish oxidation of the dissolved H2S species by interaction with the oxidized redox catalyst essentially in the absence of gaseous dissolved oxygen.  The highly oxidized polyvalent metal redox solution, including Fe+3 or V+5, contacts the H2S-laden solution from the absorber chamber for reoxidation of the dissolved HS-, S=  and any of the polyvalent metal sulfur compounds (presumably a chelated iron sulfide or a vanadium sulfide), to avoid formation of sulfate or thiosulfate salts which reduce the yield of sulfur and build up in the solution.  To avoid the formation of crystals of iron sulfide or crystals of vanadium sulfide, thereby avoiding loss of polyvalent metal, the residence time of the redox solution after contact with the H2S-containing gas and prior to contacting with the oxidized metal redox solution is limited to a relatively short time. Flow of solution from the last oxygenation stage, preferably through a valve or other circulation control device, to the reaction chamber provides controlled and continuous elemental sulfur formation in the reaction chamber.

Abstract: TOOL GUIDE AND CONTOUR SANDER FOR USE THEREWITH     ABSTRACT        A tool guide temporarily attachable to vehicle body panels or other surfaces to provide a straight edge, and a contour sander for use in connection with a straight edge. The tool guide includes an elongated member having a longitudinal edge surface for guiding a work tool, and suction cups mounted on tongues extending laterally from the body of the tool guide.  The tongues are angled in relation to the body, so that the tongues exert a cantilever force urging the tool guide against a surface when the tongues are secured against the suction cups.  The contour sander includes a number of flat blades mounted side-by-side and each having a longitudinal edge for contacting a contoured work surface.  A clamp holds the blades in parallel juxtaposition and selectively loosens the blades for conforming contact with the contour.  Finger grips are formed at the ends of the blades, allowing the operator to raise or lower any particular blade and obtain a sharper or more accurate reproduction of contour if desired.

Title: Heating and cooling system for a building
Inventor: DICK BRIAN G
IPC: F24F5/00
Filed: 1992-06-08
Abstract: A reversible vapour compression refrigeration plant serves as an air conditioner for cooling or as a heat pump for heating. A main stream of inlet air is divided into separate main and bypass streams of air and proportion of flow between the two streams is varied in an inverse ratio so that as flow through the bypass duct increases, flow through the main duct decreases and vice versa. When the plant is used for heating, the main stream is heated by a supply heat exchanger acting as a condenser and when the plant is used as an air conditioner, the supply heat exchanger acts as an evaporator. Also, as an additional alternative, as a desired air space temperature is approached, preferably heat rejected by a condenser in the heating mode, or heat gathered by the evaporator in the cooling mode, as gradually reduced by reducing refrigerant flow therethrough by modulating compressor suction. Full fresh air or full re-circulating air modes, or a combination of mixed and re-circulating air can be used.      Also, energy is saved in both the heating and cooling modes by locating an exhaust heat exchanger within exhaust flow discharged from the space to be heated or cooled.

Abstract: A method of controlling the allocation of a population of remote units (120) among a plurality of groups of remote units (120) is provided. Each remote unit (120) has a digital identifier respectively associated therewith. A maximum and a minimum average number of remote units (120) per group is fixed. The remote units (120) are assigned to the groups of remote units (120) in accordance with the respective digital identifiers. The average number of remote units (120) per group is then determined as remote units (120) are assigned thereto. Next, the average number of remote units (120) per group is compared to the fixed maximum number of remote units (120) per group. The above steps are repeated while the average number of remote units (120) per group is less than or equal to the fixed maximum number of remote units (120) per group.  The number of groups is changed such that the average number of remote units (120) per group is between the fixed maximum and minimum number of remote units (120) per group if the average number of remote units (120) per group exceeds the maximum number of remote units (120) per group.

Title: Hierarchical interconnection networks for parallel processing
Inventor: CYPHER ROBERT E
IPC: G06F15/80
Filed: 1992-09-23
Abstract: ABSTRACT           Two new classes of interconnection networks are described.  The new classes of interconnection networks are referred to herein as the hierarchical shuffle-exchange (HSE) and hierarchical de Bruijn (HdB) networks.  The new HSE and HdB networks are highly regular and scalable and are thus well suited to VSLI implementation.  In addition, they can be adjusted to match any set of packaging constraint These new networks are also efficient in supporting the execution of a wide range of algorithms on computers whose processors are interconnected via one of the networks fabricated in accordance with the teachings of the invention.  Such computers, also contemplated by the invention, are referred to herein as HSE and HbB computers.          Furthermore, methods for implementing the aforementioned wide range of algorithms, particularly those in the classes of Ascend and Descend algorithms, on the novel HSE and HdB computers, constitute a further aspect of the invention.

An advantage of PEG-imidates is that on reaction with  the  amino  groups  of  proteins  the  resulting derivative  still  preserves  the positive  charge  and displaces  the positive  charge away from the water-soluble polymer backbone.    Also  provided  for  are  polypeptides  of  interest derivatized by water-soluble polymer imidates.

Title: Method and apparatus for three-dimensional non-contact shape sensing
Inventor: SCHULZ WALDEAN A
IPC: G01S17/86
Filed: 1991-10-11
Abstract: This method and apparatus optically samples numerous points on the surface of an object to remotely sense its shape utilizing two stages. The first stage employs a moveable non-contact scanner (12), which in normal operation sweeps a narrow beam of light (42) across the object (38), illuminating a single point (36) of the object (38) at any given instant in time. The location of that point relative to the scanner is sensed by multiple linear photodetector arrays behind lenses (16, 18) in the scanner. These sense the location by measuring the relative angular parallax of the point. The second stage employs multiple fixed but widely separated photoelectronic sensors (26, 28, 30), similar to those in the scanner, to detect the locations of several light sources (20, 22, 24) affixed to the scanner, thereby defining the absolute spatial positions and orientations of the scanner. Individual light sources are distinguished by time-multiplexing their on-off states. A  coordinate computer (34) calculates the absolute spatial positions where the scanner light beam is incident on the object at a given instant and continuously on a real time basis to generate a computer model of the object.

Abstract: ABSTRACT OF THE DISCLOSURE. A non-residential door latch comprised of a serpentine rigid bar. Mounting plates for locating the bar through a typical gate such that a downwardly curving portion of the bar is exposed on one side of the gate to form a handle while an inwardly curving portion of the bar is exposed on the opposite side of the gate to form a striker. Horizontal movement of the handle creates a corresponding vertical movement of the striker.
