Patent DE-3841937-A1 (DE)
Title: Rotary engine
Inventor: HERTER ERICH
IPC: F01C1/22
Filed: 1988-12-13
Abstract: The rotary engine (20) has a driver (50) in the rotary piston (34) and a fixed pinion (58) meshing with an internal toothing (56) on the rotary piston (34). The driver (50) is connected to a shaft (16) which leads to the front axle (12) of a motor vehicle. An eccentric guided in the piston is connected to a shaft (18), which drives a rear axle (14). The number of teeth of the internal toothing (56) and that of the pinion (58) are selected in such a way that a speed ratio of 1:3 results between driver and eccentric. Due to the cut-in and shut-down of chambers of the engine (20) as a function of the load and the differing speed ratio of the shafts (16) and (18), the axles (12) and (14) can be driven at different speeds of rotation so that no transmission is required for operation of the motor vehicle. An optimum sealing is achieved by restricted guiding of the piston seals on the wall of the piston rotation inner chamber. <IMAGE>

Title: Conical closure for mobile containers for bulk materials, in particular for bulk materials which do not discharge easily
Inventor: LESK ADOLF
IPC: B65G69/18
Filed: 1988-12-17
Abstract: By raising and lowering the cone during discharge, bridges are prevented from forming in the bulk material. In the case of pourable bulk materials, in adaptation thereto the conical closure is opened automatically by a stop when the container is lowered. By the actuation of the container closure centrally below the container, a dust-tight casing of the outlet of the bulk material is applied in a very simple manner.

Title: Transport system with a rail-guided vehicle and a rail switch
Inventor: MISSELHORN WINFRIED
IPC: B61J1/00
Filed: 1989-01-11
Abstract: In order to pass from a first section of rail (11) to a second section of rail (12), a vehicle has wheel arrangements (2,3,4,5) which can be pivoted about vertical pivot axes (6,7,8,9) and the two sections of rail contain subrails (13,14,15,16) which can be pivoted together in the intersection area and whose pivot axes (18,19,20,21) are arranged at the same distances (a,b) as the pivot axes (6,7,8,9) which are fixed to the vehicle, so that pivot movements of the subrails (13,14,15,16) bring about, after corresponding positioning of the vehicle, pivoting of the wheel arrangements (2,3,4,5) out of the alignment according to the first section of rail (11) into the alignment according to the second section of rail (12) (Figure 1). <IMAGE>

Patent DE-3903618-A1 (DE)
Title: Noise protection walls made of waste products
IPC: E01F8/00
Filed: 1989-02-08
Abstract: The noise protection walls in the form of concrete rings are filled with a mixture of waste materials consisting of: sewage sludge, refuse compost, sawdust, comminuted Styropor remains, flue dust, bark from trees, foliage, comminuted plastics, slag, etc. The disadvantage of the sewage sludge (does not release water, water content about 70%) is utilised here as an advantage, this constantly high water content allowing plants to take root quickly. Sewage sludge is hygroscopic and absorbs moisture from the air when water is required (if plants have absorbed water), and stores rainwater. The systematically trapped seepage water from the mixture of waste materials is collected and pumped back into the system circuit again, it being unable to pass into the subsoil. Waste materials are thus sensibly recycled, with cost savings in the structural component produced. Possible applications: noise protection walls, vision screening walls, glare protection walls, plantable partitions and enclosures. <IMAGE>

Title: Process and winding station for the production of a fault-free cross-wound bobbin
Inventor: WEY EDMUND
IPC: B65H54/08
Filed: 1989-04-08
Abstract: The running thread (3) is monitored. When a fault occurs, the cross-wound bobbin (14) is stopped automatically in the shortest possible time as a result of the actuation of quick-action braking devices (50, 51). An interruption of the thread (3) is thus avoided. Only after the standstill is the thread (3) severed as a result of the actuation of a thread-severing device (9) and the fault eliminated and replaced by a knot or a splice by means of a device (19). The winding operation is subsequently started again without delay. <IMAGE>

Title: Colour television transmission system e.g. D2-MAC - uses transmission of auxiliary signal in vertical blanking intervals for image enhancement
Inventor: WESTERKAMP DIETRICH DR
IPC: H04N7/015
Filed: 1989-04-15
Abstract: The transmission system uses progressive scanning of the video camera image, to obtain a line iamge after sampling and filtering.  The quality of the transmitted television image is enhanced by transmission of an auxiliary signal in the vertical blanking intervals, obtained from the difference between the original signal at the output of the filter and a prediction signal. Pref. the difference signal has a limited bandwidth and it may be subjected to a time compression prior to its transmission. ADVANTAGE - Enhanced quality of received image.

Title: Hydraulic installation for heavy vehicle - has magnetic valve blocking or opening by=pass to regulate rear wheel braking effort according to load
Inventor: KLARER MARTIN
IPC: B60T8/48
Filed: 1990-07-14
Abstract: The heavy vehicle has separate front and rear wheel brake circuits and an ABS control. The rear wheel brakes (13,14) are linked to the brake system by proportional control valves (31,32) which provide an increasing brake force with increasing rear axle loads. These valves are bridged by the ABS control valves (43,44) which prevent rear wheel locking. - For normal operation the increasing loading results in increasing brake effect from the rear wheels. This relieves the front wheel brakes from excessive braking effort. If the rear wheel brakes start to lock, the normal ABS system protects the vehicle. The load regulators are mounted near the rear suspension, as are the proportional valves.
