Title: Lattice-type chess apparatus for playing chess in a plurality of spatial planes
Inventor: STRAHL GERHARD
IPC: A63F3/02
Filed: 1981-11-17
Abstract: Apparatuses for three-dimensional chess, for two or, in the case of crossover chess, for four players playing three-dimensional chess against each other or in teams, in various horizontal and vertical planes. Crossover chess and lattice chess are designed as floor-standing apparatuses for seated or standing chess players. The transposition of the game of chess into different spatial planes brings a new and increased attraction to the game, improving the spatial perception and powers of concentration and memory. Lattice chess consists of a square supporting frame which is open and stands vertically in space, and in which open lattice squares are incorporated in the chessboard pattern, the edges of these squares consisting of steel strips or of oval rods. Crossover chess for four players is made up of two lattice-type chess apparatuses, separated at the centre, so that a crosswise apparatus is obtained in which only horizontal, black-and-white strips now form the playing surfaces. In crossover chess, genuine three-dimensional chess is played: each of the players plays simultaneously against two other chess players. For example: the players white and yellow sit opposite each other while the players red and blue also sit opposite each other. White simultaneously plays his first move against red and blue. If, for example, white's men have reached the 90 degree line of red, sitting to his left, the yellow player, in the interaction of white and yellow, also takes over white's men and vice versa, and continues playing these men as his own, playing together with his partner white. The same applies to the players red and blue. In crossover chess played all-against-all, the players move their own men throughout the entire crossover chess, and naturally also change their seating positions, for example when one of the players has been mated and his remaining men have also been taken over by the victor. <IMAGE>

Title: Heat-insulating body of a fine-particle insulating material compacted by pressing
Inventor: KUMMERMEHR HANS
IPC: B32B19/04
Filed: 1981-12-10
Abstract: A heat-insulating body of a fine-particle heat-insulating material compacted by pressing, to which mineral fibres and opacifiers are added, has a surface which, even with the addition of a hardening binder, is mechanically susceptible, in particular not very abrasion-resistant and tends to crumble if the pressed material (4) is not pressed in a sheathing, for example of glass fabric. To overcome this disadvantage, at least one of the surfaces (4a) of the heat-insulating body (1) is provided with a laminating web (2) or a covering layer (2a). The laminating web (2) may be anchored in particular to the surface (4a) of the pressed material (4) by an adhesive which penetrates into the surface and forms there an adhesive layer (3). By means of a covering layer (2a) of appropriate layer thickness (d'), it is possible to compensate for unevennesses of the surface (4a) of the heat-insulating body (1). <IMAGE>

Title: Corner and longitudinal connecting profiles
Inventor: DROSTE WILH-KARL
IPC: F16L9/22
Filed: 1982-04-21
Abstract: The object of the invention is to transport large-volume ventilation ducts consisting of metal sheets in a space-saving manner, to avoid transportation damage and to achieve universal installation on site. The type of prefabrication of these large-volume ducts in a workshop, which is now widespread, could be avoided by using the invention. Storage of the individual duct components is simplified. The transportation capacity from the store of the ventilation installer to the site is increased many times. The duct components can be assembled on site using light electrical tools. The invention essentially consists of various cold-rolled profiles. The profiles are used for the corner and longitudinal connection of metal sheets, which are in this way formed into a hollow body with a rectangular or square cross-section, whose ends can be open or closed.
Patent DE-3226414-A1 (DE)
Title: Device for the mounting of conductor cables
Inventor: KAEUFL OTTO DIPL ING
IPC: H02G1/04
Filed: 1982-07-15
Abstract: The invention relates to a device for the mounting of conductor cables on supporting insulators for the cable line of medium-voltage overhead lines over angle towers. Angle towers are erected at the angle points in the course of a sector which is not straight in order to absorb the resultant force of the conductor lines at the angle points. Since the resultant force tries to pull the conductor cable away from the angle tower, it is difficult to lay the conductor cable from the cable roller for example into the head groove of the supporting insulator. The invention is based on the object of creating a device by means of which the conductor cable can be laid safely and in a simple manner from the cable roller for example into the head groove of the supporting insulator. This takes place according to the invention such that two cable rollers which are arranged on both sides of the supporting insulator can be pivoted in the direction of the resultant force on the conductor line, and such that the cable rollers can be lowered so that the conductor cable can be placed directly into a clamp of the supporting insulator.
Patent DE-3230637-A1 (DE)
Title: Protective device
Inventor: FUCHS HUBERT
IPC: B01F35/60
Filed: 1982-08-18
Abstract: The protective device relates to an enveloping tube or a covering for a rapidly operating, axially accelerating aerator for sewage. A hollow shaft, which is provided at the free end with propeller-like wings and has an air-outlet opening, pluges obliquely into the sewage in the extension of the axis of rotation of the aerator motor. By a special design of the protective device, it is possible on the one hand to protect the aerator from changing influences of the weather and different sewage consistency and on the other hand to run it under optimal incident-flow conditions, too. In this arrangement, a plastic housing surrounds the entire aerator with electric motor, extending beyond the end remote from the hollow shaft with a space all round, the housing portion surrounding the end, remote from the hollow shaft, of the aerator with the propeller-like wings having a diameter which is smaller than the diameter of the cylinder-like housing portion surrounding the electric motor, and its housing end edge, facing the sewage surface and delimiting an end opening at the top, lying closer to the propeller-like wings than the diametrically opposite housing end edge.

Patent DE-3240774-A1 (DE)
Title: High-voltage switch chamber
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/91
Filed: 1982-11-02
Abstract: As a result of the further development of high-voltage switch chambers having switching gas precompression (DE-OS 3113325, P 3234971.8), the new embodiment satisfies particularly more stringent requirements on the switching capability. The precompression time is reduced by a double-acting compression system. This simple new system provides an annular piston (84), initially on the movable gas outlet tube (16) which supports an arc switching piece (17). Said annular piston slides with its edge in a gas-tight manner along the supporting tube (11a) during switching. An annular piston (80) is mounted on this supporting tube. The gas outlet tube (16) slides on said annular piston (80). This creates an additional compression space (B). The switching gas which is compressed therein flows through an annular channel (81) into the primary compression space (A) and, after release of the nozzle inlet flow, into the nozzle space. As a result of this pneumatic parallel-connection of the compression spaces (A, B), a reduction in the pressure of the switching gas which would detract from the interrupting effect is prevented. During switching-off, an intermediate reservoir for the switching gas opens. The pressure of the switching gas in the space (C) on the hollow transition cone between the arc switching piece (17) and the gas outlet tube (16) and on the piston (84) supports the switch drive. <IMAGE>
