  • Patent number: 5043034
    Abstract: A semi-finished product (24) composed of dry, loose covering layers (10,15) of reinforcing material and a debris material (9) of reaction resin (5) and elements (7) of variable form and volume as core (22) is used for the manufacture of moulded parts by hot pressing.
    Type: Grant
    Filed: December 14, 1989
    Date of Patent: August 27, 1991
    Assignee: Bayer Aktiengesellschaft
    Inventor: Eberhard Born
  • Patent number: 4942904
    Abstract: In order to improve the introduction or uptake of force in a hollow section (1), in particular a tube, of long fibre reinforced plastic having an integrated force induction element (2) and to simplify its manufacture, a radial enlargement (4) is pressed into the hollow section (1) by means of a moulding body before the plastic matrix has hardened, which radial enlargement tapers into a narrow section (6) towards its free end (5), the jacket (3) which is formed in the process later enclosing an expansion element (9) with a clamping member (10) which merges into a tie rod (11), the expansion element (9) lying in a form-fitting manner against the interior of the enlargement (4,47) over the length of said enlargement.

  • Patent number: 4501516
    Abstract: By using a packer which is pushed as far over an anchor as the intended length of the moulding, the cavity in a borehole in the region of the bond can be completely filled with a reactive resin. Overhead work is possible even with slowly reacting resins. By using a catalyst on the packer, the reactive resin injected into the borehole behind the packer can be made to harden very rapidly.

  • Patent number: 4334992
    Abstract: A modular block for osmotic methods of separation under pressure can be folded open and the filtration unit can easily be removed and introduced in the process. The filtration unit consists of a base plate with a membrane filter candle, and the filter candle consists of a stack of membrane filter plates. Spacers are placed between the filter plates and deflecting plates are provided to ensure zigzag penetration. The permeate transportation is displaced to the edge of the plates. The permeate issues laterally at the flange.

  • Patent number: 4223219
    Abstract: A method of and apparatus for producing texture topograms at surface layers of non-amorphous polycrystalline bodies comprises means for producing a divergent beam of monochromatic radiation. The divergent monochromatic radiation beam is diffracted at a polycrystalline body to be examined. Slit-shaped apertures are arranged in the radiation path of the diffracted radiation and extend parallel to the diffraction plane. Means for forming an image of the picture of the diffracted radiation are arranged behind the slit-shaped apertures and at a distance from the surface of the polycrystalline body and the focussed reflex.
