  • Patent number: 6684797
    Abstract: A buttonhole sewing machine comprises work piece clamps with a pneumatically actuated displacement drive for displacement relative to each other of the work piece clamps from an initial position of spread by a length of spread into a final position of spread. Only the first work piece clamp is displaceable relative to the x-y table. The displacement of the first work piece clamp is defined between two stop positions. A control unit stores data for triggering an x drive for reversed displacement of the x-y table by half the given length of spread.

  • Patent number: 6684730
    Abstract: A shifting device for an automatic transmission is provided with a shifting mechanism, which is mounted in a housing pivotably around a axis within at least one shift gate. The shift mechanism detects the shift signals electrically, electromagnetically or optically and transmits them. The shift mechanism has a locking device, which is guided with the gearshift lever along a contour of a gate. The contour is associated with the shift positions (P, R, N, D, . . . ). A device is controlled as a function of the speed and can be pivoted between at least two positions (active/inactive) around an axis and can be pivoted against the locking device in at least one shift position, so that the gearshift lever remains in the preselected shift position or is automatically returned into that shift position.

  • Patent number: 6685808
    Abstract: An electrochemical gas sensor is provided which can be assembled economically and in a few steps. The electrodes (1, 2, 3) with associated electric lines are applied in a planiform manner to a membrane strip, which is impermeable to the electrolyte but permeable to gases. The membrane strip (6) is deposited in the sensor housing in a zigzag-folded pattern, so that the membrane strip limits the opening of the sensor housing for the entry of the measured gas. The electrodes (1, 2, 3) are arranged stacked in the sensor housing (5, 7) at spaced locations from one another due to the membrane strip (6) deposited in a zigzag-folded pattern.
