Title: Process and apparatus for connecting two conveyor-belt ends
Inventor: WRESSIG HEINRICH
IPC: F16G3/10
Filed: 1987-12-16
Abstract: The invention relates to a process for preparing the point of connection of two conveyor-belt pieces with cables embedded in the longitudinal direction therein as reinforcements, in the case of which process the ends which are to be connected are first of all cut in accordance with a specific geometry matched to the cable arrangement, the individual cables are then exposed, apart from a small remaining rubber layer, the exposed cables provided with the rubber layer are then roughened by means of hard bristles and are finally wetted with a chemical bonding-agent system. In order to improve the transmission of tensile force from cable to cable via rubber by means of simple measures to be carried out on a building site, it is proposed to guide the roughening bristles around the cables essentially in the circumferential direction of the same. The score marks then run in the remaining rubber layer of the fanned-out reinforcements, in the circumferential direction thereof. In order to carry out this roughening process, in which the roughening bristles preferably enclose the cable which is to be roughened in each case, the invention proposes an annular brush which rotates essentially about the longitudinal axis of the cable which is to be roughened.

Title: Process and apparatus for multi-stage compression with intercooling of vapours
Inventor: BECKMANN GEORG DIPL ING DR
IPC: B01D1/28
Filed: 1988-06-09
Abstract: In a thermal drying and concentration process, it is proposed to compress the resulting vapours and to use the compressed vapours for heating the dryer 1 or concentrator. In this case the compressed vapours are condensed, the condensate having a higher pressure than the surroundings. According to the invention, this pressurised condensate is now depressurised in accordance with the compression stages of the compressor 2, 2', 2'', this condensate simultaneously serving for cooling the compressed vapour, so that the mechanical compression effort is decreased with simultaneous increase of the amount of compressed vapour. As a result of the invention, the connection requirement of the dryer is reduced to a single energy source, so that the control effort is also simplified. <IMAGE>

Patent DE-3834017-A1 (DE)
Title: Method and device for rotational speed measurement
Inventor: KAHLEN HANS PROF DR ING
IPC: H02P6/17
Filed: 1988-10-06
Abstract: Highly dynamic variable-speed electric drives require contactless speed measuring devices which output a high pulse number per revolution of the engine. The object of the invention is to specify a measuring method for this purpose and a simple and insensitive speed measuring device. The object is achieved by a method which uses a speed measuring device with a pulse generator system and a pulse multiplying stage. The pulses output by the pulse multiplier stage also have time intervals in phases of a change in rotational speed, which are inversely proportional to the actual rotational speed. The method can be applied with particular advantage in three-phase screw-cage motors, in which case a cage (end, short-circuiting) ring can be constructed as the generator wheel of the pulse generator system. <IMAGE>

Title: Method for the improvement of the absolute positioning accuracy of positioning drives driven with at least one gear linkage, especially of robots, as well as positioning drive, especially robot, having a device for carrying out the method
Inventor: GERSTMANN UWE DIPL ING
IPC: F16H57/00
Filed: 1988-11-18
Abstract: For the improvement of the positioning accuracy of rotary drives, especially of robots, the load-dependent moment is measured in at least one gear linkage. With the aid of the compliance characteristic curve (torsion angle as a function of the moment) of the gear linkage, the angle of rotation of the gear linkage is then readjusted by a corresponding drive angle. The compliance characteristic curve is stored digitally in a store, and the motor current of the gear linkage drive is used for the determination of the load-dependent moment.

Title: Injecting multi-reagent resin into rock - by pumping them in constant proportions from separate tanks through identical pipe lines to valves and then static mixer before injecting
Inventor: RICHTER A DIPL ING
IPC: E21D9/00
Filed: 1989-08-24
Abstract: Synthetic resin reagents are uniformly mixed together for injection into rocks to stabilise them. In the process the reagents have separate tanks and are pumped separately to a probe device where they enter a static mixer and are then injected as a mixt. The system evens out losses in flow or pressure in both streams and also evens out their air content. The two resin reagents are pumped (5) from their respective tanks (2,3) to their pipelines (8,9) and are combined together beyond non-return valves (13). The flow together into the static mixer (11) and thence to the probe used (10). The two reagents are passed through identical flexible pipes (8,9) and in identical vols. so that they are equally proportioned in the mixer (11). The system uses precise pressure valves (14) and the non-return valves (15) are of a wear-resistant type hardened valve seatings and balls with polished finish. The valves are combined together into one unit in a combined pump (5). ADVANTAGE - The process maintains a constant required volumetric ratio between the reagents used.

Inventor: ROTH WOLFGANG DIPL ING
IPC: F04C29/02
Filed: 1989-09-07
Abstract: The proposal is for a blade cell compressor designed to compress a medium. The blade cell compressor comprises a cylindrical chamber arranged in a part of a casing in which runs a cylindrical rotor which is in (almost) sealing contact with the chamber wall along at least one generatrix and has radial longitudinal grooves in which blades are guided which divide the working space between the surface of the rotor and the chamber wall into cells, and with a lubricant tank which is under intake pressure during the operation of the blade cell compressor and which is linked via a supply line passing through the rotor to at least one lubricating groove arranged in at least one of the two facing surfaces of the rotor and a cover plate covering the chamber in the housing. In order to stop the flow of lubricant from its high to the low-pressure side owing to the overpressure still prevailing in the lubricant tank after the blade cell compressor has been shut down, a valve acting against the direction of supply is arranged in the supply line which opens when the rotor is running and closes when it is stopped.
