Patent EP-0358392-A2 (EP)
Inventor: COHEN DONALD M
IPC: A61B1/005
Filed: 1989-08-25
Abstract: A miniscope catheter which is constructed to allow the operator to control the deflection of the catheter tip. The catheter miniscope of the invention includes a catheter body (12) having at least one lumen. An optical filament (30, 32) is positioned through this lumen and is secured to the catheter at a location proximate the catheter distal end. In order to provide for the deflection of the catheter tip portion the catheter miniscope further includes a means (34) which can be operated to apply a force against said optical filament to longitudinally drive the optical filament in at least a first direction within the lumen. This longitudinal movement of the optical filement causes a bending moment in the catheter tip to deflect the tip. By providing that the optical filament can be longitudinal moved in opposite longitudinal directions the catheter distal tip can be made to deflect in two opposing directions.

Abstract: In a method and device for detecting the gear engaged in a vehicle, in which gear the engine speed is measured, the speed of rotation of the driven wheels is measured, and the quotient formed from the engine speed and the speed of revolution of the wheels is formed, the speed of rotation of all the driven wheels is measured in order to detect the gear as accurately and free of errors as possible. Then, the mean value is formed from the measured speeds of rotation of the wheels. Next, the quotient of the engine speed and the mean value is formed. The quotient is compared with predetermined values which characterise the possible transmission ratios of the gears and the gear is output at which the comparison results in the identity of the quotient with the associated value. <IMAGE>

Abstract: Disclosed is a process for preparing a polyarylene sulfide, which involves polycondensing a dihalogenated aromatic compound with a source of sulfur in an organic polar solvent while dehydrating at pressure under which polycondensation is performed. This process avoids dehydration operation of the raw materials, particularly the source of sulfur, prior to polycondensation, thereby resulting in the production of the polyarylene sulfide having a high molecular weight.

Abstract: Local power range monitor strings (Fig. 2A) typically including four vertically spaced monitoring sites are provided in the core of a boiling water nuclear reactor. Each monitoring site includes a conventional local power range detector (M) in which fissionable material (64) exposed to thermal neutron radiation produces fission fragments, ionizes a gas (68) and produces a current between an anode and a cathode. Each local power range detector (M) is provided with one or two adjacent gamma thermometers (T). Each gamma thermometer (T) includes an interior mass (74) heated by gamma radiation, a thermocouple (78) for measuring the heated mass and a reference thermocouple (80) connected in series. Both the local power range detector and the gamma thermometer(s) are arranged in a string with individual connecting cables leading to external connectors, one for each detector and gamma thermometer. When the string is inserted into the core and the reactor operated at a steady state, the gamma thermometers are utilized to calibrate the local power range detectors in conjunction with a conventional reactor heat balance. By the expedient of referencing the gamma flux to the output of the heat balance, calibration of the local power range monitors occurs over their useful in-service life.

Abstract: A sealing strip arrangement for a rotary piston engine comprises a rotor (16) which revolves in a casing (10), divides the latter into working chambers (14) and has a slot (18) at at least one vertex. The slot (18) accommodates a radially movable sealing strip (30) which nestles against a running surface (12) in the interior of the casing in a sealing manner. To improve sealing between the sealing strip and the running surface (12) of the casing, the slot (18) has a narrower inner region (20) and a wider outer region (24), each with radially extending side walls (21, 22; 25, 26) connected to one another by radially outward-directed step faces (27, 28).

Abstract: The invention relates to a process, by means of which waste material in landfills, preferably from old dumps in domestic refuse landfill sites which are no longer active, or from old dump areas of sites still operating, can be reprocessed in order to reduce the original extent of the landfill site at a later stage and hence to recover useful areas. After coarse materials have been sorted out, the material taken from the landfill is subjected to float fractionation in water basins, in which biodecomposition with production of a biomass also takes place. Combustible floating materials, excess biomass, combustible coarse materials and biogas obtained from biomass are burned to release useful energy. Ash and incombustible material, which is comminuted if necessary, require substantially smaller landfill areas for dumping.

Abstract: A quick connector for fast connection of fluid carrying assemblies such as a mating tube (T) and a fluuid unit. The connector (10) includes a connector body (12) which houses the connector components and accepts a redundant clip which pushes an upset bead (B) of the male tube (T) toward an annular seal (22) which surrounds the end of the male tube (T). The redundant clip (16) includes fingers (16a,16b) which are received within an external groove (12a) on the connector body (12) when the tube bead (B) is in the fully locked position within the housing (12). The fingers (16a,16b) of the redundant clip (16) proved a secondary locking feature in the event that the locking fingers (20a) of a primary locking within the connector body should fail. The posiotion of the redundant clip (16) provides a visual indication of a positive lock of the connector. The forward end of the annular seal (22) within the connector body (12) includes a unidirectional shut-off valve (26) of duckbill seal which precludes outflow from the connector in the event of unintended or accidental disconnection of the mating tube (T) from the connector (10).

Abstract: This invention is concerned with display apparatus of the Head-Up-Display (H.U.D.) type which finds utility in e.g. fighter aircraft. The invention is concerned with providing a H.U.D. which has a profile depth (PD) which is substantially and preferably much less than the diameter of the exit lens. The arrangements of the H.U.D. include a cathode ray tube (CRT) display source, a collimating optical means having a plurality of lenses with at least an entrance lens (ENL) and an exit lens (EXL) together with a prism (PM) and a combining means (CM) for combining displayed visual information with the view of the scene or object. The prism (PM) is so arranged in relationship to the display source (CRT) that internal reflection of light from the display source (CRT) within the prism (PM) and transmission of light towards the combining means (CM) is such as to enable the modular unit profile depth (PD) to be between 40% and 60% less than the exit lens (EXL) diameter. Embodiments are shown which incorporate compensating means (FOW, WFP, WO1, WO2) to compensate for (CRT) mechanical axis (MAC) tilt at an angle with respect to e.g. the aircraft horizontal (ACH).
