Patent DE-3640881-A1 (DE)
Title: Process and apparatus for water softening
Inventor: BOEHM HARALD DIPL CHEM DR
IPC: B01J49/30
Filed: 1986-11-29
Abstract: The invention relates to a process for the regeneration of the ion exchanger of a water-softening unit by means of an electrolyte, to a process for disposal of the water which arises during regeneration and which is enriched with substances causing hardness, in washing machines and dishwashers, and to an apparatus for carrying out the process. In the known processes and apparatuses, the regeneration of the ion exchanger takes place by means of an electrolyte, e.g. common salt, to be added. This is uneconomical and pollutes the waste water. These problems are solved by the electrolyte being produced by an electrochemical reaction in the process water of the water softening unit. The disposal, in washing machines and dishwashers, of the water enriched with substances causing hardness is expediently effected by the substances causing hardness being removed from the water fed in the programme steps of the operating programmes in which the wash or rinse process requires water without substances causing hardness and the water enriched with substances causing hardness being added back into the process steps in which the causers of hardness are harmless.   <IMAGE>

Title: Display element
Inventor: WING HOWARD
IPC: A47F5/08
Filed: 1987-02-19
Abstract: The invention relates to an elongated display element for use as display arrangements on building walls. The display element has a plurality of front strips, arranged parallel to one another and extending longitudinally, a first locking structure, which extends longitudinally parallel to the strips on one side of the strips and projects laterally beyond the closest of the strips, and a second locking structure, which extends longitudinally and parallel to the first locking structure on the other side of the strips and lies under the closest of the strips. Adjacent elements can be interconnected by a catching of the respective first and second locking structures of the elements, which leads to the strips of both elements being uniformly separated from one another. An assigned structure is integrally attached to the strips and combines with the strips to form at least one T-shaped slot. The opening of the slot separates the strips, and the remaining part of the slot lies under mutually adjacent strips. The strip which is closest to the first locking structure of the first element is suitable for combination with the strip which is adjacent to the second locking structure of the second element, to form a further T-shaped slot, the opening of this T-shaped slot separating the strips from one another.

Patent DE-3738320-A1 (DE)
Title: Motion-generating mechanism
Inventor: OBRA BART R
IPC: F16H35/02
Filed: 1987-11-06
Abstract: A gearwheel (50) with a relatively large diameter in a mechanism for generating a cyclical motion is produced and inserted into the mechanism in such a way that, although the gearwheel does not form a complete circle, jamming with a meshing gearwheel (80) is prevented while, in the cycle end positions of the gearwheel, there is zero backlash. After the teeth have been formed on the blank of the gear, a series of diametral measurements is performed to determine the point at which the maximum diameter intersects the pitch circle. A radius of this point of intersection, which is larger than the envisaged radius of the pitch circle, is then used to establish a centre point of the blank, around which the central opening (52) is then cut in order to provide the axis of rotation of the finished gearwheel. This axis is arranged in such a way that, when the gearwheel, having been installed in the mechanism, is in engagement with the gearwheel (80) of a gearbox (82), there is zero backlash between these two gearwheels when the point from which the centre-point radius was determined is in the engaged position, and the radial distance from the centre of rotation of the gearwheel to its pitch circle at this point is greater than at any other point of the pitch circle. <IMAGE>

Title: Healthy tennis racket with protection against tennis elbow
Inventor: KULLMANN WILTON
IPC: A63B49/00
Filed: 1988-05-26
Abstract: On use of commercial tennis rackets, the impulse from hitting causes earth radiation to be absorbed from the environment. This adds up and accumulates in the elbow or in the entire racket arm to form painful charges known as tennis elbow or tennis arm. In table tennis, it is the bat hand which is charged up, but painful charge foci can also occur on the lower part of the body due to charge transfer. On use of the healthy tennis racket in which a metal wire open at the top is integrated, the absorbed radiation is directly carried away with every hit.
