  • Patent number: 5069483
    Abstract: This invention is directed to a useful improvement in a seat belt mount mechanism of a seat belt for use in an automotive vehicle of the type that an anchor plate adapted to support the seat belt at the middle portion thereof is fixed securely to a door sash element of a vehicle body by way of a fixing bracket, and in which one end of the anchor plate is operatively introduced into an opening formed in a center pillar of a vehicle body in a state that a door is closed, wherein there is provided a latch engagement of a substantially T-shaped cross section at the leading of one end of the anchor plate. With this arrangement, the latch engagement of the anchor plate may positively be held from disengagement with the opening in the center pillar, when the door sash element of the vehicle body is deformed from a shock load, and also this possible deformation of the door sash element of the vehicle body from such a shock load may be prevented to a minimum.

  • Patent number: 5069317
    Abstract: A pneumatic shock absorber has a piston rod extending out of its cylinder whose pressure space adjacent to the piston is connected via an inlet check valve. An outlet valve to let off compressed air during damping motion of the piston has a valve piston running in a valve chamber which it divides into two chamber parts. The first chamber part connects a duct leading to the pressure space with an outlet valve. This connection may be interrupted by the end face of the valve piston acted on at least in part by the pressure in the pressure space of the absorber and cooperating with a valve seat. The second chamber part is connected with the pressure space or with the pressure source. There is a spring urging the valve piston towards the valve seat. As a result there are not losses in pressure in the two abutment positions and the damping effect is very even and continuous.

  • Patent number: 5068653
    Abstract: A capacitance length and/or angle measuring device has a transducer comprising a stationary part (1) forming a scale and a part (2) displaceable parallel over the surface of the scale, at a short distance therefrom and acting as a sensing unit. The opposite surfaces of the scale and sensing unit are provided with capacitor coatings (5,6,7,8,9). The mechanical quantity to be measured causes an area vibration of a capacitor, the capacitance variation resulting therefrom acting as a variable capacitive reactance in a circuit, which changes the phase position of the electrical signals. With an appropriate configuration of the capacitor surfaces one obtains a linear function between the mechanical quantity to be measured and the phase portion of the signals.

  • Patent number: 5065524
    Abstract: The device for measuring the internal diameter of tubes 2 consisting of two interconnected measuring units 3 and 4 that are connected to one another. The first measuring unit 3 is formed by a measuring head 9 in conjunction with a displacement transducer 7, which is axially displaceable within a tube 2. The axial displacement of the measuring head 9 is determined by a length measuring device consisting of a friction wheel 25 associated with a rotation transducer. To achieve this, the friction wheel is in functional connection with a flexible tube 24 which is rigidly connected to the measuring head 9. Thus, this measuring device makes it possible to determine internal diameters at two positions located at axially spaced locations from one another in a tube 2.

  • Patent number: 5065978
    Abstract: A valve arrangement from microstructured components worked out of a basic body, for the control of fluids, include an actuation element which is movable relative to a flow path distributor and opens or closes fluid paths depending on its position. A transition from one position into the other is effected by adding an actuating drive connected to an electrical power source. The actuation element is held in its switch position. For a high fluid flow, a large force can be applied to the actuation element. The actuating drive works according to an operating principle aimed at covering the longest distance possible. A holding device is provided, which works according to an operating principle working independent of the first operating principle and provides the generation of the greatest cohesion possible.

  • Patent number: 5066072
    Abstract: The hydraulic brake pressure control valve is provided including a valve casing mounted on a master cylinder of a hydraulic brake system. A valve piston is provided with a stepped configuration with an enlarged diameter portion and a reduced diameter portion. The valve piston is mounted slidably and longitudinally along the longitudinal bore of the valve casing. The valve piston is normally urged into a non-operating position and is shiftable longitudinally in an opposite direction from the non-operating position under the effect of a difference in the cross-sectional areas of the enlarged and reduced diameter portions, upon which hydraulic brake fluid pressure acts. The stepped valve piston is defined with a brake fluid passage extending longitudinally therein providing communication between brake fluid passages adjacent the reduced diameter portion and the enlarged diameter portion of the stepped valve piston.

    Abstract: The present invention pertains to a development of can caps for cans 1, 2 whose lids have a circular edge bead 3 as well as a wall section 4 that can be torn up to form a pouring opening 5. In order to close cans 1, 2 of different diameters with the same cap, the present invention provides for a longer, curved front edge web 9 and a plurality of individual webs 10, 11 at different locations from the curved front edge web 9, on the other hand, on the basic body 7 of the cap. The radial spacing 12 between the individual webs 10, 11 corresponds approximately to the thickness of the lid edge bead 3 of the can 1, 2. All the webs 9, 10, 11 are shaped such that they are able to reach behind the lid edge bead 3 of cans 1, 2 of different size in the manner of a snap cap. The cap lid is sealed against the can cap via a sealing ring 8 guided and held on the cap, which is pressed against the outer surface of the lid surrounding the pouring opening 5 of the can lid.
