Abstract: A rotary tablet press has upper rams (18) and lower rams (19) which are sealed off from the mould shelf (15) of the press by respective intermediate walls (28) in which all the rams (18,19 respectively) are clamped at their head ends to the free ends of individual sleeves (45), with the other ends of these sleeves being secured to the edges (44) of circular apertures (43) formed in the intermediate walls. These circular apertures (43) surrounding the ram shanks (20) with a spacing, so that the intermediate walls (28) are not stretched when the rams (18 and 19) carry out upward and downward movements.

Abstract: A roll winding machine with at least one winding shaft on which the winding sleeves are received has a support shaft carrying the pressing rollers and swingable toward the winding shaft on arms. The eccentric rings of the pressing rollers are provided with formations for coupling them together without relative play when the pressing rollers are brought together to form a gapless junction between them.

Abstract: A detergent containing 5 to 50% by weight of at least one surfactant, 0.5 to 60% by weight of a matrix substance and also standard laundry aids, contains as matrix substance an amorphous, low-water sodium disilicate having a water content of 0.3 to 6% by weight which has preferably been produced by partial dehydration of commercially available powdered amorphous sodium disilicate having a water content of 15 to 23% by weight.

Abstract: A swinging and sliding door for a vehicle, especially a motor vehicle, with a door panel, with at least one pivoting arm secured to the wall of the vehicle, with a carriage articulated to the end of the arm and sliding back and forth on a carrier connected to the door panel, and with a drive mechanism secured to the wall of the vehicle and having one wheel that drives a flexible linear-transmission structure guided by rollers and attached to the door panel to generate the sliding motion and another wheel that generates the swinging motion. The axis of rotation of the first wheel and that of the second wheel are concentric with the axis of rotation of the pivoting arm and both wheels can be coupled to a common motor by way of automatic clutches.

Abstract: An exterior swing-out and sliding door for vehicles, especially motor vehicles, in which the door panel travels on a roller carriage along a track on the outer wall of the vehicle approximately between the horizontal midpoint and the lower longitudinal edge of the panel, in which additional guides are positioned in the vicinity of the upper and/or lower longitudinal edge of the door panel, and which has a drive mechanism with a motor that drives by way of a driving roller a continuous, flexible, linear transmission that extends around pulleys, that is fastened at one point along its circumference to the roller carriage, and that has its driving strand positioned along the track.

Abstract: A process and a device for cleaning inner or outer walls of vertically extending or inverted tubes of heat exchangers and especially for cleaning tubes in trash incinerators. The process involves imparting kinetic energy to the tubes in an axial direction and then suddenly stopping the tubes to shake loose dirt and the like. The device for the process includes arranging a plurality of rows of vertically extending tubes such that the tubes move upwardly and downwardly in the direction of the axis of the tubes. The tubes advantageously include their own lower distributors and upper headers. These distributors and/or headers rest on a movable cam or cam plate which, for example, may be rotated so that a radially extending offset of the shoulder of the cam permits the cam to lift the upper headers upwardly to a height at which point they are suddenly dropped.

Abstract: A waste incinerator, especially for waste products from the chemical industry, comprising a horizontal, stationary or revolving, combustion chamber, and a vertical, brick lined afterburning chamber with circular cross section. The steel casing of the afterburning chamber is supported on an exterior furnace framework by means of a supporting ring on the chamber above the burner supported on a horizontal supporting frame. An upper steel casing segment of the afterburning chamber is separated from a lower steel casing segment above the entrance of the horizontal combustion chamber by a separating joint. The afterburing chamber above the joint is suspended by a supporting ring engaged over a horizontal frame of the furnace framework. The joint is spanned by a compensator.

Abstract: A swingable sliding door for a vehicle, comprising a guide assembly on the top of the door traveling in a guide rail arranged above the door, the guide assembly comprising a swing arm pivotally attached to the door and including an arcuate, reversely bent portion connected rigidly to a roller assembly which travels in the guide rail. The bent portion of the swing arm straddles an end post of the door opening when the door is in open position to maximize the access opening when the door is fully opened.

Abstract: A tablet press with a mould table and with multi-part rams whose movable ram parts slide along a stationary ram part having an internal hollow space connectable periodically to a suction device which removes, by suction mouldable material, dust which has penetrated in the interior of the movable ram, thus preventing the ram from being blocked with multiple material dust and making frequent cleaning and servicing of rams necessary.

Abstract: Inorganic-organic foams are obtained by foaming a mixture of(a) a 5 to 60% by weight aqueous alkali metal silicate or ammonium silicate solution,(b) a sufficient amount of a conventional hardener for aqueous silicate solutions,(c) a polymer of (meth)acrylic acid or a copolymer of acrylic acid and methacrylic acid or of (meth)acrylic acid and a copolymerizable monomer containing ethylinic double bonds, the polymer and copolymer being soluble in the aqueous silicate solution, some or all the carboxyl groups of the polymer or copolymer, where relevant, being neutralized by a base and the amount of polymer or copolymer being 0.1 to 30 parts per 100 parts of SiO.sub.2 contained in the aqueous silicate solution,(d) a blowing agent,(e) a surfactant having a foaming action and, where relevant,(f) gelling agent for solidifying the foam before hardening and/or conventional fillers, and allowing the foam to harden.The foams can be used as insulating materials in the construction industry.

Abstract: A compound construction panel for double floors used in room air conditioning, comprising an external, tub-shaped sheath formed of a high tensile-strength and high Young's modulus material, a filler in the sheath formed of a low tensile strength and low Young's modulus material, and a rigid annular body disposed in an aperture in the bottom of the sheath and extending to the upper portion of the sheath. The annular body is anchored in the filler and is provided with a radially inwardly projecting annular flange at its lower portion which serves as a support for an air discharge nozzle, a dirt-catcher or the like.

Abstract: In conventional polishing machines, uneven transmission of pressure causes ifferent degrees of abrasion of the polished discs which results in different thicknesses over one disc and also with respect to other discs in one polishing batch. This problem is solved according to the invention by the provision of soft elastic inserts between the pressure piston and the back of the carrier plate on which the discs to be polished are cemented.

Abstract: A connection for the ends of the supporting straps of an endless bar belt conveyor, especially for agricultural machines, the bars of which are connected to the supporting straps by connecting members such as rivets and screws. Within the region of the two ends of each supporting strap there is provided a connecting member which engages the inner side of the respective adjacent supporting strap and is connected to the supporting strap by means of connecting elements such as rivets or preferably screws. The connecting member comprises a pull-resistant flexible layer which extends in the longitudinal direction of the supporting strap and has a thickness less than the thickness of the supporting straps.
