Title: Sludge collector and light liq. separator - from sewage with two tanks in single housing and cover
Inventor: DIEFENBACH GUENTER
IPC: B01D17/00
Filed: 1975-10-22
Abstract: Plant, for the sepn. of settled material and light liqs. from waste water and sewage, comprises a sludge collector and a separator for the light liqs; they form a compact installation in a common housing, with a cover. The water to be purified arrives at the inlet; material which settles out is deposited in the collector whilst the liq. passes over the overflow and under the partition into the separator. Here the associated light materials, such as oil, petrol, fats, etc. float to the surface while the water passes under the partition to the outlet. when the sepd. materials pile up sufficiently to be evacuated, a pump is brought into action; the light liqs. are withdrawn through one pipe and the sludge by another pipe. The layer of floating material is first broken up by the prodn. of a powerful, horizontal jet by the injector, making use of recycled water. After the evacuation, the collector and the separator are washed by water. The sepd. materials do not need to be evacuated by hand but can be sucked out by a pump when necessary or at regular intervals; this can be followed by a complementary washing.

Filed: 1977-02-26
Abstract: The door leaf can be moved out of the door opening and can be subsequently displaced parallel to the plane of the wall and is suspended on at least two roller carriers (15). The invention is based on the object of permitting separate mounting of roof and side wall on a superstructure and at the same time permitting a guide housing for the suspension of the door to be produced by the joining of these two parts, it being impossible for the door to fall out of the suspension. The divided roof edge rail (6, 11) consists of a roof rail (11) which has the connection parts for the roof (27) and a wall termination rail (6, 6') for the connection of the side wall sections on each side of the door opening and at the same time for forming the upper door frame. Roof rail (11) and wall termination rail (6, 6') are connected to one another via integral central elements (8, 8', 9). In the area over which the roller carriers (15) move during the displacement of the door leaf, the inner width (22) between the roof rail (11) and the wall termination rail (6, 6') is smaller than the corresponding width (23) of the roller carrier heads (19) located in the roof edge rail. In this way, the door (1) can no longer fall out of the guide housing formed by the roof edge rail. <IMAGE>

Title: Contact assembly for circuit-breakers - has permanent magnet attached to one contact button to dissipate arc on contact separation
Inventor: STURM HERMANN
IPC: H01H9/44
Filed: 1977-12-07
Abstract: The contact set is designed to increase the switching capacity of circuit-breakers and contactors both on DC and AC and to prolong the life of the contacts. The contact assembly comprises pairs of contact studs (1, 2) either operating as an isolated pair or as twin pairs mounted on a common contact spring or leaf. One of the studs (1) is constructed partly or entirely of contact material such as silver or tungsten, the other stud is in two parts. The upper, mating part is of the usual contact material whereas the lower part is in the fofm of a permanent magnet (3). The lines of force of the magnet are symmetrically disposed about its central axis. This magnet field interacts with that produced by the arcing current to cause diffusion of the arcing point over the contact surfaces of the contact studs. Plasma formation is considerably reduced and the arc is extinguished very quickly.
