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.

Abstract: A combination of sulfur-free azoles, preferably benzotriazole and tolyltriazole, with sulfur-containing azoles, preferably 2-mercaptobenzothiazole or mercaptobenzimidazole, prevents discoloration, staining, or corrosion of metal surfaces being coated with an organic protective coating from aqueous dispersion or solution.
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.

Abstract: The invention relates to an adhesive system for labeling containers, more especially hollow containers, with wrap-around labels. The adhesive system comprises a pick-up adhesive and an overlap adhesive. It is characterized in that, in the wet state, the pick-up adhesive has sufficient wet bond strength for labeling and, in the dried state, does not adhere to at least one of the substrates. The pickup adhesive contains 5 to 85% by weight and preferably 5 to 60% by weight of at least one water-soluble polymer based on casein, starch, dextrin, glucose, polyvinyl alcohol, polyurethane or polyacrylic acid, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one defoamer, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one preservative and water as the balance to 100% by weight.

Abstract: A spray dryer apparatus and method suitable for the production of detergents, cleaners and components thereof wherein the inner wall of the drying chamber is provided with an air-permeable textile material lining at a distance from the inner wall, and at least one outlet for compressed gas is provided between the inner wall and the textile material lining whereby adherence of sticky deposits on the inner wall of the drying chamber is avoided or reduced.
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.
Abstract: Complexes of the transition metals cobalt, iron, copper, and ruthenium having at least one and preferably at least five ammonia ligands are used to activate peroxygen compounds in aqueous cleaning solutions for hard surfaces. Compositions preferably contain 0.0025% to 0.25 by weight of the activating complex.

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.
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.

Abstract: A zinc phosphate-type conversion film having microfine-sized crystals is formed on metal surfaces using a conversion treatment bath that contains zinc ions and phosphate ions along with 50 to 1500 ppm of an organoperoxide conversion accelerator, and optionally surfactant. Surface-conditioning treatments can be omitted from this method.
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.
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.
Abstract: Hotmelt adhesives with a melt viscosity of >100,000 mPas at 160° C. are suitable for bonding substrate halves in the production of digital versatile discs (DVDs) and afford major process-related advantages over known UV-curing adhesives. In their pigmented embodiment, they are able to combine the three functions of adhesive bonding, protecting the metallic reflection layer against corrosion and forming a covering background for a text/graphics layer.

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.
Abstract: The invention relates to the use of mutated protease of the subtilisin type which carries at least one mutation in its amino acid sequence, leading to a reduced positive charge or an increased negative charge in the substrate binding region of the molecule, in liquid to gel-form laundry detergents. This protease shows increased stability above all in detergents such as these.
