Title: Method and apparatus for flow control for sensor calibration
Inventor: MERRICK EDWIN B
IPC: G05D7/06
Filed: 1993-01-21
Abstract: METHOD AND APPARATUS FOR FLOW CONTROL FOR SENSOR                     CALIBRATION     ABSTRACT OF THE DISCLOSURE     The improved gas flow control apparatus controls the flow of multiple gases to a tonometer for calibration of a blood gas or pH sensor and compensates for the failure of gas supply solenoid valves to operate properly in controlling gas flow.  Intermediate gas supply solenoid valves select between gas flow of the supplied gas in an open position, and venting to the atmosphere in a closed position.  A common selector valve is also provided in the gas flow path to the tonometer to select gas flow from one of the intermediate gas flow valves.  A control unit is provided for controlling the operation of the intermediate and common selector valves.
Patent CA-2089586-A1 (CA)
Title: Knotless fishing line connector
Inventor: KISSAU LARRY E
IPC: A01K91/03
Filed: 1993-02-16
Abstract: ABSTRACT OF THE DISCLOSURE     A connector attaches fishing line to a sinker, line weight, float, lure, hook, swivel, or the like. This connector is in the shape of a coil. One end of the connector is embedded in, attached to or part of the body of a sinker, line weight, float, lure, hook, swivel, or the like. The other end of the connector is located near the body so that it is exposed enough to permit a loop of fishing line to be passed over the end. A connection is made by passing a loop of line between the connector and the body one or more times, then placing the loop over the exposed end of the connector and pulling the ends of the line to tighten the loop against the connector. The number of times that the loop is passed between the connector and the body will determine if a slip connection is made or if a secure connection is made. Connection can be made at any location on the line without tying a knot in the line. Disconnection is done simply by pushing the loop back along the connector until it passes the exposed end. Once the loop is clear of the exposed end the fishing line is simply pulled free of the connector.

Abstract: ABSTRACT OF THE DISCLOSURE       The process described for producing locket-halves comprises the following steps: A locket-half body is formed from a first sheet. All annular groove is stamped in a second sheet, the external diameter of the groove being substantially the same as that of the locket-half. The part of the second sheet enclosed by the inner edge of the groove is removed, thus giving an annular plate.  The locket-half body is laid with its edge in the groove. The edge of the locket-half body is welded to the annular plate. The part of the second sheet which, after the groove was stamped in it, extended beyond the outer edge of the sheet is then separated from the annular plate.

Patent CA-2113660-A1 (CA)
Inventor: BUI-KHAC TRUNG
IPC: C07K14/78
Filed: 1994-01-18
Abstract: The present invention relates to a process of making a concentrate of coagulation proteins starting with whole human or animal plasma. This concentrate is used as a biological adhesive when extemporaneously mixed to thrombin. The concentrated proteins include mostly fibrinogen, fibrin stabilizing factor (factor XIII) and fibronectin. The claimed process has the advantage of being short of execution while providing an excellent yield of coagulable protein. No protease inhibitor has to be added during the process. The process involves steps of separation by "salting-out" in presence of amino-6 hexanoic acid which prevents co-precipitation of plasminogen with the desired coagulable proteins. The proteins so obtained are very stable after reconstitution in water for at least 24 hours at room or body temperature. After mixing with thrombin and calcium, the adhesive shows excellent strength and biocompatibility.

Patent CA-2125712-A1 (CA)
Inventor: ANDREWS JOHN R
IPC: G03G21/00
Filed: 1994-06-13
Abstract: A method and apparatus is provided for registration of color images on a photoreceptor belt.  Registration is accomplished by forming, in one embodiment, a chevron-shaped registration marks in non-image areas of the belt.  A Raster Output Scanner (ROS) sweeps an output beam across the belt's surface.  The beam is modulated in accordance with input video data to form successive color images.  An unmodulated beam is also swept across the registration marks, each mark being successively swept by a plurality of beams.  With each crossing of the legs of the chevron, two signals are generated by an associated sensor and stored in an averaging and extrapolation circuit.  The multiple signals are compared and detection of the intersection is calculated by an extrapolation method.  The averaging circuitry generates a registration signal which is used to enable an accurate start of page signal, to correct for skew and to adjust for errors and line-to-line spacing between lines in a color image frame.

IPC: A61N1/365
Filed: 1994-08-29
Abstract: A multiple sensor cardiac pacemaker blends the outputs from a fast-reacting Activity sensor and a slower-reacting Minute ventilation sensor to achieve an optimally desirable pacing rate. The pacemaker conserves battery energy by forcing the Minute Ventilation sensor output to be at its minimum value by disabling the Minute Ventilation algorithm for a predetermined time period when the Activity sensor is at its minimum observed value. Power is conserved because the Minute Ventilation sensor and associated algorithms which normally consume power to operate the circuitry, and to measure impedance are disabled temporarily only during selected periods where the Activity sensor is at its minimum observed value, thereby maintaining optimal blending of the pacemaker sensor outputs in achieving the desired pacing rates.
