Patent DE-3245571-A1 (DE)
Title: Needle shut-off nozzle for injection moulds
IPC: B29C45/23
Filed: 1982-12-09
Abstract: A needle shut-off nozzle for injection moulds, with a shut-off needle which can move back and forth, has on the shut-off end of the needle a cylindrical sealing region of reduced diameter, it being possible for the transition from the larger to the smaller diameter to be of a conical or rounded design. In the front needle region, a precentring element for the shut-off needle is provided, which element tapers on its inner side conically in the closing direction and has in this case such a cone inclination that, upon a deflection of the needle, not its sealing region but the next larger shoulder comes into contact with the wall of the precentring element. The sealing region is thus not unduly stressed in any event. As propulsion, plungers arranged coaxially with respect to the needle may be provided, for example, so that transverse forces caused by rocker arms are avoided. Furthermore, inwardly open channels are provided in the precentring element, so that in this region as well the moulding material has to be conducted through colder regions.

Title: Process and apparatus for jacking pipes over an underground jacking way
Inventor: BERTHOLD ALFRED
IPC: E21B7/20
Filed: 1982-12-18
Abstract: When jacking pipes over an underground jacking way, the control head 4, provided with the excavating unit 6, is supported by a guide tube 2 by means of control cylinders 5 which provide the possibility in the event of alignment errors of readjusting the control head 4 with respect to the guide tube 2 by appropriate tilting. Unwanted adjustments and tiltings which may occur are sensed by a light-optical aiming device 12/13, in which photodiodes arranged in planar formation in the vicinity of the control head 4 are impinged with a light beam. Whereas in the past the relative position between light beam 14 and target 12 has merely been indicated to the operating crew controlling the operation, according to the invention the output signal of the photodiodes respectively impinged by the light beam 14 is utilised after appropriate amplification to actuate hydraulic control valves 20, by which the control cylinders 5 receive the required corrective adjustment (Fig. 1). <IMAGE>

Title: Process and device for purifying water
Inventor: PAWLOWSKY ERNST
IPC: C02F3/22
Filed: 1983-02-16
Abstract: The process serves for the biological purification of water after a prior clarification using a prefilter. In combination with a clean water chamber (see figure), the process has its own water filter circuit, via an integral pump having an air feed nozzle or an air-driven mammoth pump. By this means are produced the aeration, (oxygen introduction), an increase in the flow velocity of the water in the filter mass and a continuation of the water supply and oxygen supply of the filter substrate having a biological slime in the event of a failure of external water feed. The filter substrate used is preferably lava gravel having a particle size of 10-15 mm. Other correspondingly porous materials are likewise usable. By means of the column-shaped design, a high hydraulic loading, consisting of the water feed and filter circuit, of the filter mass is produced, which is preferably 30,000 to 150,000 l/h per m<2> of filter cross-sectional area. The following possible uses are given for either stationary or mobile designs of the novel filter system: individual and multiple aquarium units, biological water purification in intensive fish farming, swimming pools, drinking water purification in emergencies, flooding and from rivers, treatment of industrial waste waters, particularly textile mills, laundries and other wet operations. <IMAGE>
