Title: Screen structure and process and apparatus for the production thereof
Inventor: SCHNEIDER HORST
IPC: B28B23/02
Filed: 1987-10-16
Abstract: A description is given of a screen structure and of a process and an apparatus for the production thereof. The screen structure is distinguished in that it exhibits an anchoring portion which is designed as a concrete protrusion. In this manner, the screen can be mounted with the aid of a simple plug-in connection, whereas complex and time-consuming casting in concrete is dispensed with. In the process, the concrete protrusion is first of all produced on a suitable connection reinforcement, whereafter the connection reinforcement is connected to the principal reinforcement. The screen structure is then cast, the concrete protrusion being integrated. The apparatus comprises a special casting mould which is suitable for casting screens of different lengths.

Title: Extending the measuring distance of a position encoder (displacement sensor)
Inventor: KREFT HANS-DIEDRICH
IPC: G01B7/00
Filed: 1988-08-30
Abstract: This invention relates to a device for economic contactless determination of the position of a moving part (e.g. conveyor trucks) along long measuring distances by means of the POMUX position encoder. In this case, position indicators (magnets) are mounted along the measuring distance and POMUX is mounted on the part to be positioned. If POMUX knows the position of a position indictor detected by POMUX, the position is determined by I-p1 (see Figure 4). POMUX does not determine any absolute values from the distance between two adjacent magnets whose characteristic distance is a measure of their absolute position with reference to a zero point. <IMAGE>

Patent DE-3901733-A1 (DE)
Title: Method and device for liquid fuels
Inventor: SCHEFFEL BERND
IPC: F02M53/02
Filed: 1989-01-21
Abstract: When heating fuels before they are injected, the temperature must not rise above a particular value appropriate to the pressure because otherwise vapour bubbles form. In known devices which heat the fuel by means of heat from the exhaust, the pressure chosen is very high in order to prevent vapour bubbles given the high temperatures and large temperature fluctuations of the heat from the exhaust. High injection pressures lead to a high outlay on construction. Excessively high fuel temperatures are not permissible with applied ignition engines because of knock phenomena. The fuel is heated by means of an auxiliary medium which, when condensed, releases its latent heat to the fuel. By controlling the pressure in the condensation range, it is thus possible to keep the fuel temperature constant within a narrow range irrespective of fluctuations in the fuel flow and of the temperature of the heat source. The heat is added to the fuel on a different temperature level to that of the heat source. Together with an arrangement of an injection pump (9) and a feed pipe (15), it is possible to achieve optimum pressures and temperatures in the fuel during preheating. The method and the device make it possible to use fuel preheating particularly in the case of applied ignition engines and thus provide a means of achieving better mixture formation with a view to improving exhaust emission figures and fuel consumption. <IMAGE>

Moreover, at least one of these surfaces can be moved for continuously conveying the material 10 to be mangled, and in addition at least one of these surfaces can be pressed by means of a device onto the surface lying opposite. The two surfaces together form inlet and outlet positions 48, 50 for the introduction and removal, respectively, of the material 10 to be mangled. <IMAGE>

Title: Device for removing phosphate(s) from waste water or sewage - by circulating algae parallel to the sewage flow but sepd. from it by water-permeable partition through which the algae cannot pass
Inventor: SCHOELL STEFAN
IPC: C12M1/00
Filed: 1989-07-14
Abstract: The process makes use of algae which after multiplication are skimmed off the liquid surface, and which are prevented from flowing away with the sewage by a separating wall which is impermeable to them. The sewage inlet and outlet are on the same side of the partition, and the water pressure on the sewage side of the partition is equal to or greater than that on the algae side. The region containing the partition is kept in darkness, and the algae suspension is circulated parallel to the sewage flow. Illumination is provided at a separated point on the algae circuit. Carbon dioxide is added to the algae suspension, which may be heated. The skimmed off excess algae are dried and burnt. USE/ADVANTAGE - This invention is used for removing phosphates from waste water by means of suitable algae. The proposed system is more economic and efficient than existing systems in which the sewage inlet and outlet are on different sides of the algae-retaining partition.
