Abstract: Solvent-free coating materials and treating agents used as water-based wood or material protective agents containing emulsifiable binding agents, quaternary ammonium compounds and optional additional active agents. The wood or material protective agents are non-flammable and enable a uniform distribution of the binding agent and the quaternary ammonium compounds in the substrates. As a result, the quaternary ammonium compounds function as a dissolving mediator for the binding agents which are dispersed in water without opacifying effects and are used as a biocide. The agents can additionally absorb water-insoluble organic biocides without impairing the homogeneity or stability of the formulation of the homogeneity of the distribution in the substrate.

Abstract: Lids, for example, lids for machine-lidding of, e.g., beakers, dishes, menu dishes, goblets, small packages, etc., containing a substrate material featuring, with respect to a container on which the lids are used, a smooth outward facing surface bearing printing. On the inward facing side of the lid is a sealing layer deposited by extrusion laminate coating. The sealing layer exhibits on the free surface embossing with a depth of roughness of up to 50 &mgr;m. The embossing is transferred to the sealing layer in the form of a roughness pattern on the cooling roll on depositing the laminate coating of the substrate material and extruded sealing layer. The free side of the substrate material is smooth and exhibits no embossing. Printing on the free surface is therefore of higher quality. The extruded sealing layer on the substrate material exhibits embossing on the free side. If the lids are drawn from a stack of lids, for example, in a filing machine, the embossing allows them to be separated individually.

Abstract: A process for manufacturing a strip of aluminium or an aluminium alloy for electrolytically roughened lithographic printing plates, in which the alloy is continuously cast as a strip and then rolled to final thickness, is such that the cast strip is rolled to final thickness with a thickness reduction of at least 90% without any further heating. The resultant microstructure in the region close to the surface of the strip leads to improved electrolytic etching behaviour.

When the golf bag is tilted in direction diametric to the pivotal attachment of the bottom unit, the bottom unit, in effect, pivots in relation to the bottom of the elongated container, and the push rod means is moved towards the top of the elongated container, thereby pivoting the legs outward.

Abstract: Packaging (10) featuring a tear-off closure with an tearing aid for freeing an opening (34) to remove the contents (32) is such that, at least in the region of the opening, layers of packaging material forming an outer (20) and inner part (22) of the packaging are superimposed, separated or separable from each other. The aid to tearing is arranged on the outer part (20) of the packaging in such a manner that the outer part of the packaging is separated from the inner part of the packaging a distance (a) from the opening and the inner part of the packaging is exposed in the region of the opening. The inner part (22) of the packaging which is revealed on tearing open the packaging is free of germs with the result that the packaging is suitable for consuming drinkable and/or edible contents by mouth directly from the packaging.

Abstract: In order to detect pin-holes or tears in a foil (16), during deformation of the foil (16), the transmission of light through the foil is measured continuously by means of at least one light source (22) situated on one side of the foil (16) and at least one of the light sensors (24) on the other side of the foil (16). The light source (22) is integrated in a shaping-punch (14) and the light sensors (24) are situated in a die (12) which is employed along with the punch (14). The pin-hole detector (10) enables pin-holes or tears formed during the deformation of the foil to be detected on-line in a single shaping step closely resembling actual working practice.
