Title: Method of placing and connecting diaphragms in trench walls and apparatus for carrying out the method
IPC: B29C65/20
Filed: 1984-08-22
Abstract: The invention relates to a method of placing and connecting diaphragms in trench walls. To this end, inner and outer slit connecting tubes are to be attached to the perpendicular diaphragm boundaries. The slit connecting tubes are telescoped when the diaphragms are put into the trench-wall section. The inner space of the connecting tubes is then emptied. Devices for cutting, cleaning and connecting the overlapping diaphragm ends are then subsequently moved in the inner space of the connecting tubes so that a permanent, continuous and tight connection of the perpendicular diaphragm boundaries in the trench wall is produced as a result.

Title: Machine for dicing potatoes and other vegetables
Inventor: RUSCHMEIER GERHARD
IPC: B26D3/18
Filed: 1984-11-24
Abstract: A machine for dicing potatoes and other vegetables. A machine is described which comprises three main parts, which in their turn comprise a plurality of individual parts. The base part comprises the screwed-on end board, the wooden angle which acts as reinforcement, the wooden recessed block for the cutter and the wooden end pieces. The article to be cut is placed in front of the wooden recessed block for the cutter so that it can be cut horizontally using the pulling device. The pulling device comprises the cutting device, which is screwed onto the pulling rods 10, and the pulling handle. The pulling device is pulled along horizontally between the cutter guiding rods, until the article to be cut, which is situated in front of the wooden recessed block for the cutter, has been cut all the way through. The third unit comprises the pressure cutter, the holding rods and the wooden pressure plate. When it is pressed downwards onto the wooden recessed block for the cutter, the cut article is diced. If relatively hard articles are to be cut, the floor extension plate and the auxiliary pulling device are used. The waste board is used to remove from the unit bits of the diced article still remaining in the pressure cross-cutter. The unit, which comprises the pressure cross-cutter and the holding rods with the wooden pressure plate, is taken and pressed over the waste board.

Patent DE-3508916-A1 (DE)
Title: Process and installation for purifying waste water
Inventor: KOCH ARNIM
IPC: C02F3/30
Filed: 1985-03-13
Abstract: The process serves for purifying waste water with the aid of plants whose roots, in interaction with soil substrates and microorganisms, bind and degrade pollutant substances contained in the waste water. In a first purification stage, oxygen is fed under aerobic conditions to the waste water and nitrogen compounds contained in the waste water are nitrified. In a second purification stage, under slightly anaerobic conditions, the nitrogen compounds are removed from the waste water by denitrification. Upstream of the first purification stage, oxygen can be fed to the waste water at least up to the development of an aerobic biological activation. The waste water, prior to its entry into the first purification stage, can be circulated by a circulation pump, and a waste water stream produced by this can be activated by introducing atmospheric oxygen. The installation for carrying out this process has, in the direction of flow of the waste water, purification tanks arranged one after the other in purification stages. The waste water flows through the purification tanks and plants grow in them. Upstream of a purification tank which is first in the direction of flow of the waste water, aeration feeding atmospheric oxygen to the waste water is provided. The aeration can be designed as a nozzle sucking air into a waste water stream. The nozzle can be arranged at the end of a pipe which is connected to a circulation pump producing a waste water stream in the pipe.

Title: Wind deflector for ventilation nozzles, preferably in buses
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H1/26
Filed: 1985-11-26
Abstract: It is known to equip buses with chemisorption filter technology in order to clean pollutants from the air entering the driver's area. So as not to allow the air volumes to be fed to the driver's area to become too large, it is proposed according to the invention to arrange, at the right-hand side next to the driver's seat, a hinged wind shield which extends from the area of the ceiling of the vehicle preferably as far as the shoulder height of the seated driver. The pane of transparent Plexiglas has the effect that, even during opening of the doors, the wind blowing in no longer places a strain on the driver's respiratory organs, since in the square, partitioned off with the aid of the hinged wind shield, above the driver's head, the cleaned air is forced in from the filter.
Patent DE-3544460-A1 (DE)
Title: Method for operating a RF surgical instrument, and a safety device for carrying out the method
Inventor: FEUCHT PETER DIPL ING
IPC: A61B18/12
Filed: 1985-12-16
Abstract: In the method proposed here, a RF working current is transmitted from an active electrode (14) to a neutral electrode (18) via a body (16) to be treated. Before transmission of the RF working current, a RF measuring current pulse of prescribed amplitude and prescribed frequency is guided into the active electrode (14) and compared in terms of amplitude with the RF measuring current pulse tapped by the neutral electrode (18). It is provided according to the invention that during the comparison the current (IA) flowing through the active electrode (14) is brought into relationship with the current (IN) flowing through the neutral electrode (18), as a result of which a combinatorial signal (v) is obtained, and that depending on this combinatorial signal (v) and on a comparison with a prescribed limiting value (v<*>) a release signal (g, h) is formed, e.g. for a safety measure. It is preferable for the two currents (IA, IN) to be detected by current transformers (38, 42), their logarithms to be taken in logarithmic units (58, 60), and to be subtracted in a component (68, 70). The quotient can thereby be formed virtually independently of level. The monitoring circuit works using a logic element (62) to combine the currents (IA, IN) and using a comparator (76). In addition, a level monitoring circuit (77, 82, 84) can be provided. <IMAGE>
