Abstract: In order to provide a deep-drawing method, with which a drawn part is arranged in a deep-drawing die between a first deep-drawing die part and a second deep-drawing die part and is formed by way of relative movement of the deep-drawing die parts in relation to one another, which—particularly for carrying out several consecutive drawing processes—is more time and energy saving than the known deep-drawing methods it is suggested that a pressure variable with time during the drawing process be generated selectively at a limited pressure section of one of the deep-drawing die parts, this pressure pressing a section of the drawn part abutting on the pressure section against the respectively other deep-drawing die part.

Abstract: To improve the resistance to scratching of plastic molded articles comprising a polymer matrix filled with inorganic fillers, the filler content being 50 to 90% by weight in relation to the filled matrix, it is suggested that the filler comprise two filler fractions (a) and (b), wherein the filler fraction (a) has a particle size distribution with 98% by weight of the particles having a particle size .ltoreq.150 .mu.m and is distributed essentially uniformly in the polymer matrix, and wherein the filler fraction (b) comprises particles having a particle size of approximately 300 .mu.m to approximately 3000 .mu.m, wherein the proportion of the filler fraction (b) is approximately 1 to 35% by weight of the total filler content, and wherein the proportion of the filler fraction (b) in an outer surface layer of the molded article is enriched to at least 30% by weight in relation to the total mass of the filled matrix.

Abstract: In a casting composition comprising a curable syrup which contains a liquid monomer and polymer components optionally dissolved therein, and an inorganic filler which includes a quartz sand product, in order to simplify the production of white molded articles, it is proposed that a product, the individual grain of which consists in the core essentially of quartz and at the surface essentially of .alpha.-cristobalite (low-temperature modification) be selected as quartz sand product.

Abstract: In a castable, curable composition for producing plastic molded articles, comprising a sirup containing a proportion of acrylic acid monomer and/or derivatives thereof, in order to achieve an improved boiling resistance of the plastic molded articles produced from the composition, it is proposed that a proportion of a further component of the formula (I) ##STR1## which contains an ethylenically unsaturated group of the formula (II)--R.sub.5 --R.sub.6 (II)and/or contains a group of the formula (III) ##STR2## be added. The sirup may also optionally contain a proportion of a prepolymer, in particular PMMA, and, in addition, a particulate, inorganic filler in a proportion of 50 to 90% by weight in relation to the total composition, pigments and a radical initiator system are contained in the sirup. The viscosity of the total composition is .ltoreq.100 Pa.multidot.

Abstract: A built-in sink made of a plastic composite material is secured in an opening formed in cover plate having a surface for placing a downwardly facing supporting surface of the built-in sink thereon. A securing element having a main body is attached to the built-in sink. A clamping member is held on the main body for displacement in the direction transverse to the cover plate and adapted to be tightened against and supported on the cover plate. A clamping screw is held in a thread of the main body for pressing the clamping member against the cover plate, the thread of the main body being oriented transversely to the cover plate. In order to minimize the manufacturing costs, a slot extending at least approximately parallel to the cover plate is provided in an underside area of the built-in sink located opposite the circumferential surface of the cut-out opening in the cover plate.

Abstract: A built-in sink unit with at least one basin, which has first surface areas, such as the bottom of the basin, subject to severe wear during use as well as second surface areas, such as the side walls of the basin, subject to less severe wear during use and in which the first surface areas are provided with a three-dimensional surface structure and the second surface areas are smooth. To ensure that any surface damage in the region of the surface areas subject to severe wear during use does not immediately catch the eye, the built-in sink unit gives the optical impression, when new, of really being a new article and the sink unit can, finally, be cleaned effectively with abrasive means without any disadvantageous optical effects thereby resulting, the surface structure of the first areas is formed by microgrooves at least approximately straight and extending parallel to one another, the surface roughness measured transversely to the longitudinal direction of the microgrooves being greater than 0.1 .mu.

Abstract: A table-like device is provided for preparing foods. A one-piece tabletop is made of stainless steel sheet metal. The tabletop has a central downward curvature. A heating device is arranged beneath the tabletop for heating the central region thereof. A plate-like heat transfer element, an electric heating element and a plate-like reflector are arranged, one below the other, under the central region of the tabletop for efficiently and uniformly heating the central region.
