Title: Circuit card connector utilizing flexible film circuitry
Inventor: LOPATA JOHN E
IPC: H01R12/71
Filed: 1997-04-14
Abstract: A circuit card connector (20) utilizes flexible circuitry (64) and a card-engagement assembly (50) which applies a normal force to the contact pads (34) of the circuit card (30).  The connector includes two opposing connector end portions (40) and a card-engagement assembly (50) extending therebetween, the card-engagement assembly (50) including two opposing spring members (53) which are seated upon a pair of fulcrums.  The spring members (53) are spaced apart from each other on opposite sides of a centerline of a card-receiving slot (80) of the connector (20).

Title: Hydrostatic tool with electrically operated setting mechanism
Inventor: BROCKMAN MARK W
IPC: E21B23/04
Filed: 1997-07-09
Abstract: The present invention provides a tool for use in wellbores. The tool is operated by the wellbore hydrostatic pressure. The tool includes one or more devices that operate when a mechanical force is applied to such devices.  The tool includes at least one atmospheric chamber. A setting member disposed in the tool is utilized to provide the mechanical force in response to the application of the hydrostatic pressure thereto. Prior to activating the tool, the setting member is locked or restrained in an inoperative position. To operate the device, the tool is placed at a suitable location in the wellbore.  The atmospheric chamber is charged with the wellbore fluid, which releases the setting member from its restrained or locked position, subjecting the setting member to the wellbore hydrostatic pressure, thereby providing the mechanical force to operate at least one of the devices. A second atmospheric chamber may be provided that remains at the atmospheric pressure, but cooperates with the first chamber as it is charged with the wellbore fluid to operate a second setting member, which operates a second device. A sensor associated with the tool detects signals transmitted to the tool from a remote location. A control circuit in the tool receives the detected signals from the sensor and in response thereto operates an electrically-operated flow control device, thereby charging the chamber with the wellbore fluid.

Patent CA-2211397-A1 (CA)
Inventor: WARREN KEITH O
IPC: G01P15/08
Filed: 1996-11-18
Abstract: An accelerometer is fabricated by forming a proofmass and at least one associated hinge in a silicon substrate through a variety of etching and bonding processes. The processes entail ion implantation and formation of an oxide support layer (40, 42, 44) below the proofmass, integrally bonding two complementary proofmass (62) and substrate structures together, and then removing the oxide support layer (40, 42, 44) to leave the proofmass (62) supported by the hinge (67) within the body of silicon material (12). In a bond and etch back process, the wafer (532) is processed, sawed in half, and then bonded together again wherein the complementary halves are joined to obtain the finished accelerometer. During fabrication of the composite wafer (900), the wafer (900) is mounted to a centrifuge (902), and spun to remove etchant. The centrifuge (902) is constructed from a bar shape platform (904) that is rotated by a motor (906). Two compartments (910) are lined with filter paper (912, 914, 916) that contain the composite wafers (900), and are covered by lid (918).
Patent CA-2211501-A1 (CA)
Inventor: LEIDY D WAYNE
IPC: C03B9/16
Filed: 1997-07-25
Abstract: A method and apparatus for forming a hollow article operates in a cycle utilizing two independently operated neck rings, with a conventional take out mechanism.  Since the rings have individual operating mechanisms, they can start and stop independently and move at different velocities.  This allows more flexibility in the process, since the reheat and run time can be varied without affecting the machine speed. After the blank and plunger are clear, the first ring transfers the parison to the blow mold.  When the blow head retracts, the second ring releases the container and the mold opens.  The second ring moves to the pressing station and the take out removes the formed container from the mold.  The mold cannot close until the bottle clears and the first ring arrives with the parison, and the blank mold cannot move up until the second ring is in pressing position.

Filed: 1997-08-13
Abstract: A method and apparatus for generating various tire profiles. A linear-linear- rotary table carries a non-contacting probe that sequentially scans the entire outer surface of a tire. The non-contacting probe collects measurement data which is transferred to a processor to generate an average cross-sectional tire profile or a high definition cross- sectional tire profile of the tire being measured. The processor, in conjunction with the non- contacting probe, provides an automatic ranging feature which eliminates the need to manually adjust the non- contacting probe prior to the collection of measurement data.

IPC: A61M25/00
Filed: 1996-04-19
Abstract: The invention concerns a method and device for the selective perfusion of fluids through blood vessels, controlled by the pressure in the blood vessel. The invention particularly concerns the aspiration of a fluid out of and retroinfusion of the fluid into veins, in particular coronary veins, controlled by the pressure in the vein, and the perfusion of fluids through arteries, in particular coronary arteries, controlled by the pressure in the artery.      The retroinfusate is, pumped into the blood vessel (200) through tubing (60) which is open at the proximal end and can be inserted into a vein or artery (200) of the patient. For retroinfusion from veins, the tubing (60) is connected to a suction device (90) for blood or retroinfusate from the patient's vein (200). A control unit (10) derives commands from ECG signals to synchronic the pumping and aspiration intervals with the patient's heart cycle.      During the pumping phases, the intravenous or intra-arterial pressure is measured, and the control unit (10) maintains the pressure inside the blood vessel as constant as possible at a given level during the intervals between pumping by means of a flow regulator (30).

Title: Injection device
Inventor: GABRIEL JOCHEN
IPC: A61M5/24
Filed: 1998-03-02
Abstract: An injection device has a housing (112,116) wherein there is a longitudinally movable expressing member (186) for expressing an injection fluid from a fluid container (118). In order to displace the expressing member (186) longitudinally within the housing, an actuating member (170, 172) is associated therewith.  The actuating member is displaceable between a proximal end position and a distal end position.  Between the actuating member (170, 172) and the expressing member (186), a position-dependent connecting device (166", 167", 198, 210, 212) is provided, which is disabled in the distal end position of the actuating member (170, 172) and is enabled in a position range adjacent to the distal end position of the actuating member (170, 172) including its proximal end position. One thus obtains an injection device which is simple to operate, and which is especially adapted to permit a patient to repeatedly administer the same constant injection dose.
