Patent CA-2087924-C (CA)
Inventor: GAO XINGLONG
IPC: B60K17/02
Filed: 1993-01-22
Granted: 2003-04-08
Abstract: A multifunctional energy-saving system for vehicles is composed of automatic clutch means (1) and control means (2), The automatic clutch means mainly comprises a shaft (4) with a regular prismatic section (5), a hub (6) , a synchronous cage (10) with torque-transmitting elements (12).When the speed of the shaft is higher than that of the hub, torque is transmitted between them through said elements (12). When the speed of the shaft becomes lower than that of the hub, no torque is transmitted between them. The shaft can be engaged with the hub as required at any time responding to the control means. The energy consumption can be considerably reduced by means of the present system. When the automatic clutch means of symmetric structure is used in the system and disposed in place of the original differential of a vehicle, the automatic clutch means can further function as a differential with anti-slip performance.

Title: Electronic pilot positioner
Inventor: RUDICH GEORGE JR
IPC: F15B9/09
Filed: 1993-02-10
Granted: 1995-07-18
Abstract: A positioner (100) for use in pneumatic systems moves a pneumatic operator. The positioner is an electronic pilot position-er or eletronic to pneumatic interface which provides accurate positioning of linear actuators (250) in response to an electronic control signal (561). The actuator is moved as pneumatic fluid is exhausted or supplied through the exhaust valve and supply valve. The positioner utilizes two solenoids for controlling a supply valve (302) and an exhaust valve (312). The positioner in-cludes an electronic control circuit (500) which receives a signal from a central controller and a signal from a feedback circuit (200). The electronic control circuit compares the feedback signal and the controller signal and generates a signal for positioning the actuator.

Title: Plasma fraction purification
Inventor: UEMURA YAHIRO
IPC: A61K38/43
Filed: 1993-07-13
Granted: 1998-04-14
Abstract: The present invention describes a process for activating Factor II to Factor IIa by incubating Factor II in the pressence of Factor V, Factor Xa, phospholipids, and calcium ions. Each of the factors is prepared from a single impure protein fraction which includes Factors II, V and X. The Factor II, V and X purification procedure comprises the steps of DEAE ligand chromatography and precipitation by the addition of barium chloride. Factor V is recovered from the barium chloride supernatant, and Factors II and X are contained in the barium chloride precipitate. The barium chloride precipitate is dissolved in an aqueous solution and is applied to a chromatographic resin coupled with a ligand which binds Factor X and Factor II weakly or not at all. Factor II is recovered from the fraction, which remains unbound or weakly bound to the Factor X binding ligand. Factor Xa is prepared by recovering Factor X from the ligand during the Factor II preparation procedure and activating the Factor X to Factor Xa by specific proteolytic cleavage.

Each user terminal (111,12) comprises a data compression and decompression circuit (22), a transceiver (23), and an antenna (25) for transmitting and receiving data to and from the satellite relay system (13). The satellite relay system (13) comprises a satellite (30), a wide area antenna (35), a plurality of receive antennas (32, 24), a plurality of transmit antennas (31, 33), and a signal processor (36). The wide area antenna (35) is provided for communicating command and control signals between the user terminals (11, 12) and the network control center (13). The plurality of receive antennas (32, 34) operate in a first frequency band and produce a first plurality of beams that cover a service area. The plurality of receive antennas (1332, 34) receive time domain modulated data from the user terminals (11, 12). The plurality of transmit antennas (31, 33) operate in a second frequency band and produce a second plurality of beams that cover the service area. The plurality of transmit antennas (31, 33) transmit frequency domain modulated data to the user terminals (11, 12). The signal processor (36) demodulates the time domain modulated data received from a user terminal (11), routes the demodulated data so that it is transmitted to a second user terminal (12), remodulates the data to provide frequency domain modulated data, and transmits the frequency domain modulated data to the second user terminal (12). Video cameras (21) and monitors (24) are coupled to the user terminals (11, 12) to provide for video teleconferencing.

Abstract: The invention provides a method for removing sulphur compounds from water which contains low levels of organic matter, by anaerobic reduction of the sulphur compounds to sulphide, followed by partial oxidation of the sulphide to elementary sul-phur. The cost-increasing consumption of electron donor (nutrient) during the anaerobic reduction is lowered by one or more of the following measures: a1) keeping the sulphate concentration in the anaerobic effluent at at least 500 mg/l; a2) keeping the sul-phite concentration in the anaerobic effluent at at least 100 mg/l; b) keeping the salt concentration, expressed in sodium ion equivalents, in the anaerobic medium of at least 3 g/l; c) keeping the sulphide concentration in the anaerobic influent at at least 100 mg/l; d) introducing an inhibitor into the anaerobic treatment medium, which inhibitor is more toxic to the methane-produ-cing bacteria than to incompletely oxidising sulphate-reducing bacteria or sulphate-reducing bacteria oxidising compounds hav-ing one carbon atom.

Abstract: A supported bioprosthetic heart valve is provided. The valve includes a stent (16) and a biological valve member (18). The stent has an annular frame defined by a support rail. The support rail (36) is formed to define a triad of axially-projecting circumferentiallyspaced commissure posts (38, 40, 42), each post having an inverted U-shaped configurationn and a pair of legs. Each of the pair of legs has an upper end and a lower end. The lower end of each leg merges smoothly with the lower end of a leg of an adjacent commissure post. A sleeve (48) having an inflow end (50) and an outflow end is fitted around the annular frame. The biological valve member is defined by a tubular wall (20) and three leaflets, the three leaflets being attached to the tubular wall and axially converging along three commissures. The biological valve member has a shape which fits the contour of the support rail and is disposed under the support rail. The biological valve member is sutured to the support rail and the outflow end of the sleeve. The bioprosthetic valve member also includes a suturing cuff (46) which is not rigidly attached to the support rail allowing the valve to expand and contract in the lateral direction. The suturing cuff is formed by wrapping the inflow end of the sleeve around a ring-shaped cushion and suturing the sleeve to itself encapsulating thus the ring-shaped cushion. An inflow support ring (47) may also be provided within the suturing cuff for added lateral support.
