Abstract: The invention relates to a sealing assembly for the limitation of fluid flow along a rotatable shaft that is passed through a housing member that separates a high pressure side and a low pressure side, wherein the sealing assembly comprises: a rotor with a sealing surface which essentially extends radially in relation to the shaft, a flushing sealing system that extends between the rotor and the housing member, which sealing system is in contact with both the housing member and the sealing surface of the rotor to effect a sealing effect, wherein the flushing sealing system comprises an elastic sealing member that in use imposes a targeted compression force on the sealing surface.

Abstract: A fault tolerant air bag system needs a floating supply, which supply conventionally is made by means of a DC-DC converter with a transformer. By splitting the main energy reserve capacitor (14) into two capacitors (14, 34), and coupling one of the capacitors (34) to the other (14) by means of switches (36, 38) which open during a crash, no transformer is needed any more.

Abstract: A device and a method for its manufacture, for magnetic-inductive measurement of the quantity of mixture flowing through a pipeline into which the device has been incorporated. The device includes a housing having a measuring tube with an electrically insulating lining therein. The lining substantially consists of wear-resistant, insulating ceramic material in the form of tiles applied on a layer of plastic material having a thickness between 3 and 10 mm. The joints between the tiles are filled with plastic material. The housing contains magnetic coils. A pair of electrodes are mounted in the measuring tube and extend through the wall of the measuring tube and are insulated in relation to it. Within the housing, the electrodes are connected to lines leading to measuring members for measuring the voltage difference generated in the flowing medium by the magnetic field of the magnetic coils.

Abstract: Shaft seal consisting of an annular body of elastic material, comprising a fastening flange (1;12), a substantially axially extending flexible hinge portion (6;13) and a sealing lip (7;14). The fastening flange, hinge portion and sealing ring (5) form a single piece, and the sealing ring (7;14) has a cylindrical contact surface with the shaft extending over substantially the entire length of the sealing ring. This length is sufficient to receive one or more tensioning elements (10,11; 15,16) of an operative width to guide the sealing ring concentrically on the shaft over its entire axial length.

Abstract: A connector system for coupling a pair of single optical fibers is disclosed. The connector comprises a connector tube, a lens spacer, a pair of positioning sleeves and positioning sleeve elastomeric stoppers, a pair of adjusting screws and a pair of clamping screws with corresponding clamping screw elastomeric stoppers. The optical fibers to be connected are cut and flame treated to form hemispherical beads or lenses on each cut end. The optical fiber lenses are spaced apart inside the connector surrounded by a coupling medium that has an index of refraction higher than the optical fibers. The fibers are optically aligned by fine adjustments such that a maximum strength is obtained.

Abstract: The invention relates to the combination of a radial bearing 4,5;38,39 and a seal 14,17,21; 42,45,46 which both make use of elastomeric bushings 6,7,17,42,45 having a smooth cylindrical surface supporting a shaft (1,36) provided with helical grooves 10,11,15,19,46 conveying the lubricating liquid said helical grooves conveying in the same or opposite directions, said combination of radial bearing and seal further can be combined with an axial bearing 40 having grooves in a disc 53 which rotates with the shaft (36) and which is in engagement with stationary discs 54,55 of elastomeric material.

Abstract: The invention relates to an axial bearing comprising a shaft 1 with a disc 2, said disc having grooves 7 and cooperates with a stationary disc 5,6 made from elastomeric material the bearing being based upon the principle that the flank 8 or flanks 8,9 of the groove 7 under all circumstances from stand still to motion at full speed deform the smooth surface of elastomeric material and form a lubricating wedge.

Abstract: The invention relates to a method of manufacturing large diameter axial sealing rings from hard-metal blocks which are placed in an annular groove said blocks being secured within said groove by filling said groove with liquid solder and circumferentially pressing the radial end faces of the blocks within said liquid solder filled groove against each other by means of radially acting clamp bolts.

Abstract: The present invention relates to a seal of a shaft being rotatable relative to a stationary housing, said shaft being provided with a groove (3, 13), said groove being spiraled such that during rotation of the shaft the groove will pump fluid from the high-pressure side towards the low-pressure side. The shaft portion provided with the helical groove coacts with an abutting flexible sleeve (6) so that the amount of fluid which is allowed to escape in a controlled manner can be determined.
