  • Patent number: 6251848
    Abstract: Bull's-eye tablets in which both the shaped body per se and the lands surrounding the bull's-eye are mechanically stable and even lend themselves to production in modern high-throughput tablet presses and in which the core placed in the larger shaped body is joined to the tablet in a stable manner and does not separate from the tablet matrix during production, packaging, transportation and handling can be obtained if the contour line of the core falls from the edge zone to the lowest point and climbs back to the edge zone.

  • Patent number: 6241378
    Abstract: The invention relates to a dosing apparatus for pastelike substances and mixtures thereof with a solvent by means of an injector, comprising an integrated shutoff device. The apparatus contains a detection device which detects the amount of paste according to conductimetry. The shutoff device is a dual piston valve closing an opening between the paste supply tube and an injector suction chamber as well as an opening between the solvent supply tube and an injector pre-chamber. The invention also relates to a method for dosing pastelike substances and the mixtures thereof with a solvent by means of such a device. By opening a shut-off device in a supply tube for a pressurized solvent, a dual piston valve moves against an opposing force. This releases a connection between a paste supply tube and an injection suction chamber, followed by a connection between the solvent supply tube and the injector pre-chamber.

  • Patent number: 6237807
    Abstract: The invention relates to a dosing apparatus with a container having a charging hole for a refill bag with a liquid in the top part, and an outlet in the bottom part. An opening device for the refill bag is fitted above the outlet. A connector leads from the outlet to a downstream pump. A chamber with a level sensor is arranged underneath the reservoir. The reservoir and the chamber are configured so as to be liquid tight, for supplying the liquid without a refill bag. A dosing pump is integrated within the dosing apparatus. A dosing conduit leads from the pump to a point of usage outside the dosing apparatus, and a return conduit leads to the integrated container.

  • Patent number: 6233826
    Abstract: A method for reinforcing a selected portion of a structural part utilizes a flexible tube having a unexpanded, preferably thermally expandable resin sheath. The sheath may be limited to a selected region along the length of the flexible tube. The flexible tube is inserted through a curved passage and conforms to the geometry of the part to be reinforced. After the portion of the tube having the sheath reaches the desired location, the tube is secured in place. Upon heating, the resin expands to several times its original volume and fills the structural cavity only at that region.

  • Patent number: 6233777
    Abstract: The invention concerns a flat floor-mop-type covering for cleaning floors, with a cover sheet which, on the upper surface, comprises pockets for securing it to a mounting and, in the central region of the lower surface, loops or strands. Strands are disposed on both sides of a seam of a peripheral strand strip. In this respect, the inner strands are short enough to insure that when they swell owing to the effect of moisture, they bend through approximately 90° in the direction of the surface to be wiped and form a type of brush ring.

  • Patent number: 6231687
    Abstract: A phosphating solution that contains from 3 to 30 g/l of zinc ions, from 0.1 to 20 g/l of ferrous ions, from 5 to 60 g/l of phosphate ions, from 5 to 60 g/l of nitrate ions, and a source of hydroxylamine in a concentration corresponding stoichiometrically to from 0.5 to 4 g/l of hydroxylamine and in which there is a weight ratio of zinc to phosphate that is from 0.1:1 to 1:1 deposits on steel to be cold worked a phosphate conversion coating suitable as a lubricant carrier. This phosphating solution, which may optionally contain one or more of calcium, nickel, cobalt, and copper cations and simple and complex fluorine-containing anions, makes it possible to lower the temperature of the treatment solution, reduce the amount of sludge, improve the quality of the coating film, and allow single-liquid type replenishment to be used. Preferably the surface to be phosphated is immersed in the phosphating solution, maintained at a temperature of 35 to 80° C., for 2 to 20 minutes.

  • Patent number: 6230941
    Abstract: The invention relates to a paste container with a follower plate tightly sealing the open side of the container. A multiblade mixing propeller is fitted to the follower plate in such a way that it can be rotated, a short distance beneath the follower plate, around an axle (5) which juts through the middle of the plate. The paste container includes a removal device with an external drive mechanism with which paste can be removed from the container through an opening in the follower plate. The agitator blades and the removal device have the same drive mechanism. The paste container is used in particular for receiving thixotropic pastes.

  • Patent number: 6228833
    Abstract: Scent intensifying washing and cleaning detergents or components for these detergents are manufactured in which a solid and essentially water-free premix is produced, said premis being comprised of washing and cleaning detergent compounds and/or washing and cleaning detergent materials. The premix contains at least 0.1 wt. % perfume referring to the premix and is subjected to granulation or compacted agglomeration. By virtue of the water-free method, subsequent drying steps do not apply in which the prefume is entirely or partially vaporized. The homogenous incorporation of the prefume leads to a substantially increased fragrance of both the product as well as the articles which are dampened or dried, especially textiles.
