Title: Calendering system
Inventor: AABERG BO-CHRISTER
IPC: F16G1/14
Filed: 1995-05-26
Abstract: The invention relates to a calendering system in a papermaking ox board manufacturing process, the system comprising at least one press nip, an endless calender belt (30) having a core (32) and a compressible, elastic material bonded to the core (32), as well as a paper or paperboard web (16) which passes together with the belt (30) through the press nip and the dewatering of which is completely or at least substantially completely terminated earlier in the manufacturing process.

Patent CA-2207502-A1 (CA)
Title: Method and associated device for removing material from body
Inventor: GELBFISH GARY A
IPC: A61M1/00
Filed: 1995-12-15
Abstract: A pull push device for removing a clot. The device includes an elongate tubular member having a suction port and an irrigation or fluid pressurization port respectively con-nectable to a vacuum source and a pressurizable fluid reser-voir. The tubular member also has a clot intake port positionable through a patient's skin inside a clogged vas-cular vessel. The vacuum source enables clot suction into the clot intake port for severing while liquid pressure supplies fluid for clot ejection and device clearance. A single piece rotating or reciprocating cutter and intake closure component is mounted inside the tubular member for closing the clot intake port upon each small vacuum assisted severing of clot mass by the cutting element. By simultaneously severing the clot and closing the intake port by the closure component, the device automatically converts from a suction to a pressure mode, thus ejecting any clot through the suction port. The ordered and continual suck, cut, push, pull tandem ejection system is aided by an automatic anticlogging mechanism which is operative when a sucked clot obstructs suction through the tubular member. This self-limiting feature closes off further suction and ends the process of clot intake. Only after window closure and clot ejection has occurred is vacuum restored to the intake port so that more clot may be sucked into the device for processing.

Abstract: Nitrile rubber can be synthesized by copolymerizing acrylonitrile and 1,3-butadiene in an aqueous emulsion.  After these monomers have been polymerized, it is, of course, necessary to recover the polymer from the aqueous emulsion.  The present invention discloses an improved method for the recovery of nitrile rubber from a nitrile rubber containing emulsion, said method comprising the steps of (1) adding an antioxidant to the nitrile rubber containing emulsion to produce a stabilized nitrile rubber emulsion,  (2) adding a salt and an acid to said stabilized nitrile rubber emulsion to produce a coagulated nitrile rubber slurry, wherein said coagulated nitrile rubber slurry is comprised of serum and nitrile rubber crumb, (3) separating the nitrile rubber crumb from the serum in the coagulated nitrile rubber slurry,  (4) mixing the nitrile rubber crumb into wash water to produce a nitrile rubber reslurry, (5) adjusting the pH of the nitrile rubber reslurry so as to be within the range of about 5 to about 8, and (6) separating the nitrile rubber crumb from the wash water of the nitrile rubber reslurry.  Nitrile rubber which is recovered from emulsions utilizing this technique typically exhibits improved stability and cure characteristics.

Title: Improved flight simulator
Inventor: MCCLINTIC FRANK J
IPC: G09B9/12
Filed: 1996-02-05
Abstract: This invention is a motion simulator (300) wherein the pitch, roll, and yaw axes are separated from the participant to provide a more realistic simulated motion experience in that the participant feels a translation as well as a rotation of his body as he performs a simulated climb or roll. The simulator includes a pitch boom (114) rotatable about the pitch axis and a swing boom (134), perpendicular to the pitch axis rotatable about the roll axis. The swing boom supports a participant compartment (160) which can rotate about the roll axis. The participant compartment has a center of gravity which is separated from the intersection of the pitch and roll axes. A counterweight (230) may be slidably connected to a second section (231) of the swing boom opposite the participant compartment and driven by a counterweight drive assembly (232) to achieve both static and dynamic balance. The simulator may be supported by a platform (302) which is rotatable about the yaw axis which intersects the pitch and roll axes. The passenger compartment may be raised and lowered along the yaw axis to permit ease of entry and egress of the participant to and from the passenger compartment.

Abstract: A single jointed rotatable and steerable drilling tool having a flexible motor stator housing, and optionally a flexible bearing housing. The flexible portions can have a reduced outside diameter or increased inside diameter, and they can be made from a relatively high yield strength, low modulus of elasticity material. Also disclosed is a method for using the tool to drill all sections of a deviated wellbore from kickoff to the desired inclination angle in a target reservoir. The tool has but one angle, such as an angled sub, making it rotatable to drill a straight hole and to increase the radius of curvature of a curved hole. The tool also has a fluid driven motor, making it operable in the sliding mode of operation for drilling a short radius of curvature. The flexibility enables the drilling tool to be used around tighter curves, and the rotatability enables the tool to drill in both drilling modes of operation to complete all sections of the lateral wellbore with a single tool.

Abstract: The tracking of mobile terminals served by base stations supported by respective switches formed into respective peer groups of switches in which the peer groups are then formed into a hierarchical logical network having a prescribed number of levels of scope S, and in which individual ones of the switches serve as a home switch for respective ones of said wireless terminals is enhanced. Specifically, responsive to receiving a registration message sent by one of the wireless terminals, the receiving switch notifies the home switch associated with the sending terminal.  The home switch, in turn, notes the current location of that terminal and sends a similar message to the switch serving the zone in which the sending wireless terminal was last located.  The latter switch, responsive to receipt of the message sets a pointer that points to (a) the current location of the sending wireless terminal if the switch is within the scope of the current location of the sending terminal or (b) the home switch if the switch is outside of the scope of the current location of the sending terminal.

Title: Image signal transmitting method, superimposed signal extracting method, image signal output apparatus, image signal receiving apparatus and image signal recording medium
Inventor: OGINO AKIRA
IPC: H04N21/2347
Filed: 1998-01-15
Abstract: The PN code generation controlling means 15 produces a PN code generation clock signal PNCLK to generate the PN code of one chip to one vertical section and supplies this clock signal to an SS duplication preventing control signal generating means 16.  The SS duplication preventing control signal generating means 16 generates the PN code of one chip to one vertical section depending on the PN code generation clock signal PNCLK and executes t he spectrum spread to the duplication preventing control signal S3 using this PN code to form  the SS duplication preventing control signal S5.          The SS duplication preventing control signal S5 is superimposed to the image signal and is then output.  Thereby, elimination and deterioration of the additional information which has been spectrum spread and is then superimposed into the image signal can be prevented to surely provide the additional information superimposed to the image signal.

Title: Slow gain control
Inventor: STOCKBURGER MARK A
IPC: A61N1/37
Filed: 1996-08-14
Abstract: A system and method automatically controls a gain of a cardioverter/defibrillator which receives electrical activity of the heart and delivers shock pulses in response thereto. An amplifier amplifies the electrical activity according to a variable gain. A detection circuit detects depolarizations in the amplified electrical activity and provides a detect signal representing a cardiac event indicative of a depolarization when the amplified electrical activity exceeds a sensitivity threshold. A storage device stores peak history information representative of peak values of the amplified electrical activity of a first selected number (N) of cardiac events. Slow gain control circuitry adjusts the variable gain in discrete steps based on the stored peak history information.
