Abstract: The apparatus has three rotational speed sensors for three vehicle axes which are perpendicular to one another. In order to be able to dispense with a vertical sensor or acceleration meter and to achieve a reduction in the dynamic range necessary, the three rotational speed sensors (1; 2,3; 4) are arranged on a common pendulum (5) which represents the vertical and which can oscillate around any desired axis within the horizontal plane, one of the three measuring axes of the three rotational speed sensors coinciding with the longitudinal axis of the pendulum (5) and being parallel to the latter, and the two measurement axes (2, 3) of the two other rotational speed sensors being perpendicular to the first measuring axis (5) and to each other. <IMAGE>

Abstract: (57) Two connectors (13,14) are used in opposition to connect electrically and physically to parallel edges of a printed circuit board (11). Moving a first actuator mechanism (16/17) on the first connector (13/14) moves the printed circuit board toward the opposite connector (14113) to a fixed position defined by a stop (48) on the other actuator and then causes a closing-wiping action of the contacts (15) of the first connector. A second actuator mechanism, located on the second connector, has operation substantially identical to that of the first mechanism except the printed circuit board does not move. The two connectors are preferably mechanically substantially identical and the actuation sequence is independent of the handle sequence. Another embodiment for contacting a single edge of a printed circuit board is disclosed wherein one of the aforementioned two connectors is replaced by a simple guideway and stop.

Abstract: A miniature, nonevacuated, detector refrigerator assembly for use in infrared imaging systems incorporates a miniature Joule-Thomson laminar refrigerator (10) which serves as the substrate for the detector subassembly (12) and electrical leads (40, 42, 44, 46, 48), as well as the primary structural element of the assembly. The detector subassembly is positioned on the cold region (14) of the refrigerator, surrounded by insulating material (20, 22, 21) and capped by an optical window or filter (28) as required. As a result, the detector is cooled while the contact pads (50-58) used for connection to external devices are at ambient temperature. A piece of high thermally conductive material (13) may be placed in the vicinity of the detector subassembly so that during operation gases in the chamber (70) surrounding the detector will preferentially condense thereon rather than on the detector subassembly.

Filed: 1984-11-12
Abstract: In order to maintain the flux in an asynchronous machine supplied by an intermediate-link converter in the event of a network disturbance, the converter is initially blocked at the beginning of the network disturbance. After the intermediate-link current has decayed, the timing of the free-running converter on the machine side and the ignition of two series-connected controlled rectifiers of the converter on the network side are effected. The flux still present in the machine induces in the stator circuit closed in this manner a machine current which is controlled by a supplemental current controller in an operation slightly on the generator side, whereby, at the expense of the kinetic energy of the synchronized machine, a current through the circuit is generated which is required for covering the dielectric losses and for maintaining the desired flux.

Abstract: Thermomechanical, chemimechanical, and chemithermomechanical pulps are produced in a manner such that they have enhanced drainage and strength, and/or can be bleached to enhanced brightness levels and in a simple manner. Chips are impregnated with chemical or thermal treating fluid, such as by passing heated sulfite liquor countercurrent to the flow of the chips (at 12). After impregnation, and where applicable cooking, the chips are washed by a countercurrent flow of wash liquid (at 13,27) including chelating and surface active agents. Immediately after washing the chips are mechanically refined to produce a mechanical pulp by passing the chips through a first pressurized refiner (14, 38), screening (at 15, 39) the pulp discharge from the first refiner to provide first (16,40) and second (17, 41) streams, passing the first stream to a second pressurized refiner (18, 43) having a discharge (19,44), and passing the second stream directly to the discharge of the second refiner. Further treatment of the pulp, including bleaching (at 21, 57) utilizing hydrosulfite and/or peroxide, is effected in order to achieve a mechanical pulp having the desired properties.

Abstract: A device for luminal recanalization of atherosclerotic blood vessels includes a guide sleeve adapted to be introduced into the blood vessel and advanced to the atherosclerotic plaque. The sleeve includes a fluid passage to conduct fluid to the distal end to inflate an exterior-mounted balloon to immobilize the sleeve and block blood flow in the vessel. A fiberoptic core is adapted to be advanced through the guide sleeve, with spacing therebetween to permit the flow of cooling fluid to the distal end of the sleeve. The distal end of the fiberoptic core is provided with a heat conductive cap which is adapted to be selectively heated by laser energy delivered through the core. The cap is advanced beyond the distal end of the sleeve to contact the plaque, and the laser energy virtually instantaneously heats the cap to cause thermal destruction of the plaque. The core may be removed to flush the plaque debris from the vessel, and to introduce an endoscopic fiberoptic core to visualize the results. In tortuous vessels, a preformed guide wire may first be inserted into the vessel, the guide sleeve advanced about the guide wire into the vessel, and the wire removed and replaced by the fiberoptic core. In a related embodiment the guide sleeve is provided with parallel channels to receive the fiberoptic core and the guide wire simultaneously, so that the sleeve may be advanced through a vessel along a guide wire with the cautery cap extended and heated reiteratively as required to remove plaque as it is encountered.

Abstract: A system for controlling fluid flow from a source to a steering motor and one or more auxiliary motors comprises a priority valve and a steering controller. the priority valve has a housing that includes an inlet port connected to the source, a priority flow outlet port, an auxiliary flow outlet port, and a pilot port. A biasing spring urges the priority valve spool toward a priority position directing all flow from the inlet port to the priority port. The priority valve includes a pilot flow conduit directing a pilot flow of fluid through an orifice to the pilot port. Pressure upstream of the pilot flow orifice acts on the priority valve spool in opposition to the spring, and pressure downstream of the pilot flow orifice acts on the valve spool in addition to the spring. The steering controller has a load sense cavity communicating with a load sense port, and a neutral vent orifice which, when the steering controller is in neutral, communicates said load sense cavity with a return port for allowing a pilot flow of fluid from the pilot port of the priority valve to flow through said steering controller to the reservoir. Upon actuation from its neutral position, the steering controller substantially restricts flow through the neutral vent orifice to the reservoir before its main flow control orifice opens. As a result, pressure at the downstream side of the pilot flow orifice of the priority valve substantially increases before the main flow control orifice opens and assists the spring to quickly urge the priority valve spool to its priority position. When the main flow control orifice is open the load sense cavity of the controller is connected to the downstream side of the main flow control orifice so that pressures across the priority valve are varied with pressure variations across the main flow control orifice in accordance with operator demand and steering load.
