  • Casing for raw sausage, a process for the production of said casing, and its use for sausage products that are air-cured
    Patent number: 4786512
    Abstract: A sausage casing of an isotropic spun fleece of at least one polyamide, containing no binding agent, is joined in the longitudinal direction so as to form a tube and is partially compressed. Further, the invention relates to a process for the production of the sausage casing and its use for containing sausage products that are air-cured. Special mechanical and elastic characteristics are achieved by partial compression whereas the gas and water permeability for the raw sausage is retained to the required extent. The casing shrinks with the filling on curing, remains wrinkle-free, does not allow grease to escape, and can be easily peeled.

  • Radial seal of a rotary piston engine
    Patent number: 4786241
    Abstract: A radial seal of a rotary piston engine with trochoidal-shaped casing inner peripheral surfacing and multi-corner piston, with which sealing strips are arranged in radial grooves in the corners of the piston. The sealing strips under pressure of the operating chambers of the rotary piston engine engage against the casing inner peripheral surfacing and respectively against under-pressure-side groove wall configuration. The sealing strip along a radial underside thereof has a narrow, deep groove extending parallel to the sides of the sealing strip. A sheet-metal strip is installed with nominal clearance in this first meshing groove and the sheet-metal strip projects beyond the groove. A groove spring for the sealing strip is inserted or installed in the base of this groove.

  • Method for securing straight tubes between two tube sheets in a pressure-tight manner
    Patent number: 4782571
    Abstract: A method and apparatus for securing straight tubes between two tube sheets in a pressure-tight manner, especially in the manufacture of heat exchangers. Tubes are inserted, with play, in bores of the tube sheets. One end of each tube is hydraulically expanded via a pressure medium to thereby press this one end against the associated tube sheet. The one end is secured to the associated tube sheet, preferably by being welded thereto. Each tube is heated in conformity with a prescribed prestress that is to be produced in secured ones of the tube to take into account subsequent operating conditions to push a portion of the non-secured other end of the tube out of its associated tube sheet until a predetermined difference in length between the cold and heated-up states of the tube is pushed out.

  • Pneumatic vehicle tire bead structure
    Patent number: 4781232
    Abstract: A pneumatic vehicle tire made of rubber or rubber-like material and having a reinforcing carcass that is anchored in the beads by being looped around bead cores that are essentially inextensible and/or resistant to compression. The bead cores have an essentially round overall cross-sectional shape. To increase the bending resistance of the bead cores, each bead core has an inner region of steel or other material of similar high strength and rigidity. Each inner region has a cross-sectional shape that is characterized by a dimension, in the radial direction of the bead core, that is greater than its dimension in the axial direction. Each bead core also has an outer region, of lightweight material, that complements the inner region to provide the essentially round overall cross-sectional shape for the bead core.

  • Resilient shaft coupling
    Patent number: 4781654
    Abstract: A resilient shaft coupling that, to transmit torque, includes an annular intermediate member made of rubber disposed between an inner rigid coupling part and an outer rigid coupling part. The intermediate member has, on its outer periphery, pinion-like rubber teeth that mesh, with provision for axial movement, with companion inner teeth of the outer coupling part. The radially inner zone of the intermediate member is embodied as a member of uniform torsional strength. For radial support of the projecting portions of the outer zone, at least one closed metal ring is embedded in the rubber concentrically of the rotational axis near the radially inner interface of the zone and near each of the axial outer surfaces. The rings are preferably in the form of cables made from wire strands. To further increase the transmissible torque, the rubber of the outer zone is harder than the rubber of the inner zones.

  • Apparatus for the adjustment of the tension in a rotating gripping device of a machine tool
    Patent number: 4781390
    Abstract: An apparatus for the adjustment of the tension in rotating gripping devices, which are operable with variable power outputs and follow (hysteresis) distinct tension-characteristics for build-up and withdrawal. In order to make possible a stabilization of the tension which is independent from the rotational speed, a desired value for the tension and an internal tolerance allotment for an upper and a lower desired adjustment value are presupposed in a control apparatus. In the control apparatus a leading regulated quantity is produced digitally for the changing of power outputs. The leading regulated quantity is reduced when the desired value approaches a presupposed amount, so that the actual value in presupposed intervals lessens regularly through the regulated quantity reduction under the desired value and is again increased.

  • Sheet-like composite element for construction purposes
    Patent number: 4774119
    Abstract: A sheet-like composite element for construction purposes. The longitudinal edges of the composite element is formed by U-shaped profiled edge members having legs that are directed toward one another and serve as supports for an inner and an outer cover layer, between which is disposed a core layer of hard foam. The edge members function as support elements, and have a cross-sectional area that conforms to the respective stress of the composite element. The hard foam core layer, which fills not only the space between the cover layers but also the hollow space of the profiled edge members, stabilizes the latter. Such a composite element permits free selection of the material and dimensions of the cover layers with a view toward the respective application of the composite element.
