  • Patent number: 9841434
    Abstract: The invention relates to a method for producing an acceleration sensor having a housing (1), which has a cylindrical or cubic basic shape, having at least one internal support (4) and having a sensor element (2) arranged thereon. According to the invention a sensor element (2) comprising a main body (29) having a head part (21) and an end face (24) opposing said head part (21) is premounted, by surrounding the head part (21) with at least one piezoelectric measuring element (23), a seismic composition (22) and a clamping ring (27). The end face (24) is subsequently positioned on the inner support (4) of the housing (1) in contact therewith to form a contact zone (7) between the end face (24) and the support (4). Finally, the sensor element (2) is welded in this contact zone (7) to the housing (1). The invention further relates to an acceleration sensor produced using said method.

  • Patent number: 7373827
    Abstract: A high-pressure sensor comprises an inner part, a housing and a sealing system located between the inner part and the housing for sealing the high-pressure sensor. The inner part has a shaft having an end face resting, by means of a clamping force, at least along a sealing line on a support surface at a projection on the housing. Each of the projection and the shaft has an inner surface and an outer surface. The support surface is arranged in an acute angle with respect to the inner surface of the projection. The shaft by means of the clamping force is supported on the housing along a support line whereby the sealing effect can be increased with increasing pressure.

  • Publication number: 20080028862
    Abstract: The invention describes a high-pressure sensor 1 with a sealing system which is a conical sealing arranged in an inwardly facing, i.e. engaging in an acute-angled manner between a projection 6 within the housing 2 and a shaft 4 of an inner part 3 of the high-pressure sensor 1. By means of a clamping force applied between the housing 2 and the inner part 3 the outer rim portion of the shaft 4 is forced to and rests on the housing 2. In this way the sealing effect increases with increasing pressure.

  • Patent number: 6695419
    Abstract: The drawer structure enables drawer space to be conveniently divided, and includes L-shaped dividers cut to a desired length and placed within the drawer, and formed in any combination of width and length to fill the drawer bottom and providing individual compartments within it. Additional division of the drawer space is provided by transversely extending dividers that are mounted to the upstanding legs of desired ones of the L-shaped dividers. These transversely extending dividers may include a number of snap-off portions to accommodate the width of the space being transversely further divided.

  • Publication number: 20030052582
    Abstract: A drawer including respective opposing ends and side members and a bottom member; a number of L-shaped adjustable divider members forming compartments in the drawer, one of the leg members of each of the divider members resting on the bottom member abutting a respective adjacent divider member and determining the width of an associated compartment and the other leg member defining the height of the associated compartment; and a pair of spaced L-shaped separator members placed perpendicular to the divider members and each one of the separator members abutting the respective ends of the divider members to form a respective compartment at each end of the drawer.
