  • Patent number: 9163764
    Abstract: A valve for opening and closing a liquid vessel or pouch, which includes a valve body having a central axis, top and bottom sides arranged transversely with respect to the central axis, and a passage opening that extends through the valve body coaxially from the top side to the bottom side. A closure element can be pressed into the passage opening by a spring element coaxially with respect to the central axis from the underside such that the passage opening can be closed in a liquid-tight manner. The closure element includes a first sealing lip which can be pressed into the passage opening with an interference fit P1 and, axially behind said first sealing lip, a second sealing lip, which can be pressed into the passage opening with an interference fit P2, wherein P2 is a stronger interference fit than P1.

  • Patent number: 6626627
    Abstract: A screw (1) is provided with a shank (3), a head (2) and a boring part (5). The shank (3) is provided with a thread (4). The head (2) has a shoulder (6) disposed at an axial distance (B) from the bearing face (12), while a portion (7) adjoining the shoulder on the shank side is provided with a tool drive (8). The head (2) of the screw can therefore be seized in axially secure manner by a tool in the region of the shoulder (6), and this tool can then simultaneously transmit the necessary torque in the region of the tool drive (8) as well.

  • Patent number: 6539826
    Abstract: In a screwing element (1) for accommodation of a fastener head (5) of a fastener (6) there are provided jaws (3, 4) for seizing the fastener head. The jaws (3, 4) can be axially inserted into or withdrawn from the holder (2), wherein the jaws in the withdrawn position can be pivotably forced apart into open position. At their free end the jaws are provided with incisions (15, 16) and, adjoining these, with gripper-like parts (17, 18) jutting outwardly toward the central axis for the purpose of engaging mechanically and/or frictionally with the fastener head (5) from behind.

  • Patent number: 6360635
    Abstract: A socket and/or insert (6) for accommodating a fastener head is inserted in a screwing attachment (1). The socket and/or insert (6) comprises two jaws (4, 5) which engage in a tubular holder (3) in which they are locked against rotation. The jaws can slide in axial direction relative to the holder (3). In their one end position, the jaws (4, 5) can be forced apart in radial direction for insertion of a fastener head. Under the effect of axial force in the direction of the arrow (23), the jaws (4, 5) are pressed into the holder (3), whereby the jaws are necessarily squeezed toward each other in radial direction by virtue of the tapered camming faces (12, 13), so that the inserted fastener head becomes firmly clamped.

  • Publication number: 20010028835
    Abstract: The invention relates to a method for determining the vertical distance between an object and a device with a changing position, especially a motor vehicle, whereby a first sensor placed in this device gives off a signal, said signal is reflected by the object, and the reflected signal is received by the first sensor. The distance between the first sensor and the object is calculated from the transit time of the signal from being sent to being received by the first sensor. This distance is used to calculate all possible positions of the object in relation to the sensor, in order to determine the vertical distance of the object. The signal reflected by the object is also received by a second sensor, this second sensor also being positioned in the device with a variable position. A path from the first sensor to the object and from the object to the second sensor is then calculated from the transit time of the signal from the first sensor to the second sensor.
