Patent DE-4112827-A1 (DE)
Title: Elevated passenger railway - has street level embarkation and elevated travelling positions via struts
Inventor: ROSENTRETER UWE
IPC: E01B25/00
Filed: 1991-04-19
Abstract: The passenger elevated railway runs along rails above the street. A motorised drive moves the cabin (16) along the running rail (32). Struts (14) hold the standing rails (30) up along side the running rail. The standing rails are used to support the cabin, using arms (18), at stopping points. By transfering the cabin onto the standing rails the cabin can be lowered to the ground allowing passengers to embark and disembark at street level. The cabin free running rails can still be used for traffic, reducing build up of cabins. Transfer from standing to running rails made using a shifting switch (42). USE/ADVANTAGE - Relieves traffic congestion both on and above the street. Used in an urban environment similar to trams.

Title: Rotation angle sensor for measuring deflection angle of shaft w.r.t. fixed part - has two potentiometers with lock preventing rotation of wiper carrier of second potentiometer when sensor not installed
Inventor: LEUTNER WILFRIED
IPC: H01C10/20
Filed: 1991-09-03
Abstract: The rotation angle sensor has a potentiometer (1) with a 360 deg. evaluation range, and a second potentiometer (2) with a planetary gear enabling evaluation of several rotations.

Patent DE-4134490-A1 (DE)
Inventor: VOLZ PETER DR
IPC: B60T8/48
Filed: 1991-10-18
Abstract: Described is an anti-blocking hydraulic brake system with a flow-control valve (20) fitted in the brake line (2). In order that the flow-control valve does not execute its control function during a normal braking operation, a check piston (80) is fitted which acts on the piston of the flow-control valve via a spring, thus holding the piston in position during a normal braking operation. The check piston acts, at the same time, as the valve-closure element for a valve in the fluid-return line.

Title: Serial comparison of bit groups in data stream - comparing contents of shift register loaded with reference data to bit stream data, and storing result in flip=flop
Inventor: MEUSLING ASKOLD DR ING
IPC: G06F7/02
Filed: 1991-11-11
Abstract: The comparison method uses externally generated reference data for comparison to the bit stream. The reference data is loaded into a shift register (n) whose contents are compared with the bit stream data using an XOR gate (G2), upon receipt of a clock pulse. The output of the XOR gate is coupled to one input of an AND gate. The AND gate output is only active upon receipt of a signal (FG2) at its second input. A flip flop stores the result. ADVANTAGE - Reduces time for comparison of binary sequences.

Title: Determining gaseous metabolites and prods. in (bio)chemical processes - by measuring vol. changes caused by variation in internal pressure, opt. with selective absorption of partic. components, e.g. for monitoring water denitrification
Inventor: STEINECKE HELMUT PROF DR ING
IPC: G01N7/20
Filed: 1991-11-12
Abstract: The amt. of gaseous metabolites or reaction prods. in (bio)chemical reactions is determined by compensation of pressure changes which are generated in a closed system by the gaseous producs and possibly by selective absorption of individual components. The new feature is that, in response to the internal pressure, the system vol. increases and the vol. change is evaluated by a control and interpretation unit and transmitted to a data display device. USE/ADVANTAGE - This method allows automated, continuous volumetric measurements of gases to be performed at constant pressure. Specific applications are monitoring anaerobic denitrification and CH4-generating biochemical processes, e.g. drinking water prodn. or waste-water treatment.

Title: Prepn. of coconut wine - by fermenting coconut extract obtd. from desiccated coconut, refined sugar and water with baking yeast, with coconut fat produced as by-product
Inventor: THEAKKUMKATTIL GEORGE
IPC: C12G3/02
Filed: 1992-06-19
Abstract: Prepn. of toddy substitute (a white, cloudy, alcoholic drink) comprises fermenting coconut extract, refined sugar and water with baking yeast, the alcohol content being dependent upon the quality of the desiccated coconut and water used. Also claimed is the prepn. of coconut fat as a by-product. USE/ADVANTAGE - The use of the coconut fat by-product for further industrial production is claimed. By using coconut extract from the nuts rather than from the tree sap, toddy can be prepd. in countries where coconut tress are unable to grow, and the process requires only a monthly instead of an at least twice daily harvest.
Patent DE-4224196-A1 (DE)
Inventor: GLAESER ARNALDO DIPL ING
IPC: B29C45/57
Filed: 1992-07-17
Abstract: The invention relates to a process for exerting a holding pressure on injection moulding materials in an injection moulding machine having an injection mould and a screw connected thereto via feed channels. To ensure the sensitive exertion of a holding pressure on homogeneous injection moulding material using simple means, the following steps are carried out: During the filling of the injection mould, the melt flows from the screws to the cavity; at the end of the filling operation, the melt flow is cut off in the vicinity of the screw orifice; during the material shrinkage phase, the volume loss is compensated for by the replenishment in the feed channel between the screw and the cavity; after completion of the cooling phase of the injection moulding material, the coherent melt flow of the plastic material in the cavity is separated from those in the feed channel; with adaptation of the melt pressure in the feed channel to the melt pressure in the screw, the shut-off to the screw is opened again and the material, forming a coherent melt flow again, is released to the feed channel; the melt flow to the feed channel is released again for the unhindered injection process without interruption of the melt strand.

Title: Load-bearing member and process for the production thereof
Inventor: GROEN ANTONIE WILLEM
IPC: E04C3/09
Filed: 1993-02-02
Abstract: In a preferred embodiment, the load-bearing member contains three tubular longitudinal elements which are connected to one another by means of a plurality of connecting elements arranged one behind the other in the axial direction. The connecting elements are formed from a lozenge-shaped metal sheet which is angled off through 90@ along a bending edge forming an axis of symmetry, with the result that two triangular plate portions are formed. Said connecting elements are welded, by means of the lateral borders in the region of the bending edge, on two tubes located one beside the other and, by means of the tips of the two triangular plate portions, on the third tube. The load-bearing member can be produced with a considerably reduced amount of work and has an interesting appearance.

Title: Process for cleaning up raw water contaminated by strippable pollutants, in particular hydrocarbons, and plant for carrying out the process
IPC: C02F3/26
Filed: 1993-07-17
Abstract: In the process for cleaning up contaminated raw water, a reactor is employed which has an outer reactor vessel and a central gas-introduction tube for an oxygen-containing treatment gas. The clean up is a biological clean up. In the annular space between reactor vessel and gas-introduction compartment there is arranged a fixed bed. The reactor is charged with a preset volume of the raw water to be cleaned up. The treatment gas is introduced from below into the gas-introduction pipe and drives the water to be cleaned up in circulation and/or moves in circulation together with the water to be cleaned up. The treatment gas is continuously fed in dependence on the oxygen requirement. The circulation is maintained until the biodegradation of the pollutants has taken place as far as a preset degree of clean up. The clean water is then removed via a sedimentation apparatus from which excess sludge is taken off. A plant for carrying out the process is also specified. <IMAGE>
