Abstract: A hysteresis brake is provided, such as for an electric camshaft adjuster, has with an excitation coil, a stator with an inner and outer stator part, and a moveable rotor with a hysteresis band which is movable between the inner and outer stator part. The excitation coil, which produces a main magnetic flux for a magnetic adjuster is arranged between the inner and outer stator part. A sensor enables the rotor and/or the hysteresis band to receive a secondary magnetic flux caused by the main magnetic flux, or enables the excitation coil to receive the main flux. An evaluation and control unit evaluates the magnetic flux received and determines angle and/or rotational speed information from detected changes of the magnetic flux.

Abstract: In a method for ascertaining the position of a mobile closing element of an injector valve in a motor vehicle engine, in which the closing element is driven by a piezoelectric element for opening or closing the injection valve and a voltage signal allocated to an electrical voltage recorded on the piezoelectric element, the position of the closing element is ascertained from the ascertained voltage signal. Through a two-way valve arranged on the injection valve, a change in the voltage signal is brought about based upon a change in the electrical voltage on the piezoelectric element as a function of the position of the closing element.

Abstract: A device for removing substances from blood or other body fluids, comprising a bundle of semi-permeable hollow fibers, the ends of which are embedded and held in a pottant, and a tubular casing surrounding the hollow fiber bundle. At the ends of the casing, inlet and outlet pipes are connected with partitioned fluid chambers formed in the casing. Different aspects are provided to improve the flow properties, for increasing the filtering efficiency, such as varying packing density along the length of the fiber bundle, a distributor disc within a cap, apertures on the circumference of the pottant and an ordered structure of the rippling of the hollow fibers.

Abstract: An arrangement for controlling a vehicle engine or transmission includes a control device arranged remotely from the engine/transmission (which provides the open-loop and closed-loop control algorithms), and a unit which is attached to the engine/transmission, and which is electrically connected directly to a plurality of sensors and/or actuators. The unit has an A/D converter for converting sensor signals into digital sensor signals, which are then converted into data bus signals by a data bus transceiver unit, for communication via a data bus between the unit and the control device. A uniform sensor/actuator interface is provided, with a plurality of parallel connections for the sensors/actuators and a connection for the data bus. A signal converter converts the sensor signals directly into the data bus signals in accordance with an open-loop/closed-loop control algorithm without the intermediate connection of a calculating means.

Abstract: A carrier for an article such as a folded multipurpose hand tool. The carrier is molded of a stiff but resiliently flexible material and includes a body to which is attached an arm that can be placed around a person's belt. The arm has a hook at its lower end that can be latched into mating engagement in a receptacle in the body of the carrier. Grip members hold an article securely in the carrier. Ears on the sides of the carrier can be used to hold the carrier while the article carried is being removed from the carrier.

Abstract: A gearshift device comprises an input unit for receiving input data which is connected via at least one data line to a first controller via which an actuator unit can be controlled for setting a gearbox, especially an automatic gearbox of a motor vehicle, and comprising at least one second controller which is independent of the first controller. The second controller is separate from the first controller and is connected to the input unit via at least one data line. In the case of a fault in the first controller, the actuator unit can be controlled by the second controller at least partially correspondingly to the first controller.

Abstract: There are described a spinnable polyester for producing fully oriented polyester yarn by high speed spinning based on polyethylene terephthalate modified by incorporation of aliphatic dicarboxylic acids as cocondensed units and which may additionally contain up to 5% by weight of further additaments customary for modifying polyethylene terephthalate, wherein modifying aliphatic dicarboxylic acids present as cocodensed units have in total from 4 to 10 carbon atoms and are present in such an amount that the glass transition temperature of the polyester is 70.degree. C. or below, the recrystallization temperature of the polyester is 180.degree. C. or below and the heat of fusion of the polyester, determined by DSC measurement, is 30 J/g or below, a polyester yarn producible therefrom by high speed spinning, which has a novel combination of high strength, high modulus and enhanced shrinkage capacity, and a process for producing this yarn.

Abstract: The invention relates to a diagonal flow filter module, particularly for ultra- and microfiltration.The diagonal flow filter module consists of a cuboid stack element (5) with alternating flow channels (9) for crude solution or retentate and filtrate channels (10), which are separated from one another in each case by a filter membrane (6). The flow channels (9) are closed off at the side walls of the stack element (5), while the filtrate channels (10) have openings at the side walls for the discharge of the filtrate. The flow channels (9) are open at the end faces of the stack element (5) and the filtrate channels (10) are closed. The ends of the stack element (5) are sealed to a housing (1) with a synthetic resin composition. Sealed to the end faces there are end caps (12) with the connections for crude solutions and retentate which, together with the seal between the stack ends and the housing (1), ensures a reliable separation between retentate and filtrate space.

Abstract: An active Wien-Robinson suppression filter connected as electrical filter in the electric transmission line from a drive-pedal potentiometer of a motor vehicle to the adjusting member of the throttle valve of the internal combustion engine; the jerking of the motor vehicle which otherwise occurs frequently, can be avoided with the use of such a filter.

Abstract: A multi-hull craft steering system having a plurality of hulls made from flexible envelopes inflated to maintain buoyancy. One of the hulls is located between the remaining hulls and is pivotally mounted for controlling the angular variation in azimuth. The hull is located ahead of the remaining hulls to permit rotation without interference. The hulls have a variable track wherein the distance between the outer hulls may be selected and locked. The craft is provided with a means for angularly rotating the outer hulls with respect to the longitudinal axis of the craft to permit first working position and a second stowed position.

Abstract: A plurality of drive elements, such as electric motors supplied with sprockets, are located along a threading path for the paper web of a rotary printing press; a threading element, such as a sprocket chain of a finite length somewhat longer than the maximum space between drive elements is moved along the path, for example, in a guide channel, the threading element cooperating with switches located adjacent the drive elements to energize the drive element adjacent a leading edge of the threading element, and move the threading element along to the next threading element, the trailing end turning the switch OFF since drive power will be supplied by the next drive element along the path. This sprocket chain carries a gripper with which the leading edge of the paper web to be threaded into the printing press can be gripped.
