Title: Position detection system for reversible driven robot axis - uses modulo register to record number of rotations corrected for difference angle between final and initial positions
Inventor: GROHMANN THOMAS DIPL ING
IPC: G01D5/245
Filed: 1989-10-24
Abstract: The position detection system uses a pulse generator providing a succession of output pulses corresponding to respective rotation angles of the axis, fed to a modulo counter (MZ) which is indexed in the forwards or reverse direction dependent on the direction of rotation of the axis, so that the obtained count value represents the position of the axis. The counter (MZ) is coupled to a modulo register (R1) and a count register (R2), with the difference angle between the beginning and end position (A1, A2) over a difference internal detected for correction of the modulo sum, held in the modulo register (R1). The modulo sum is increased by 1 when the difference angle is less than 180 degrees and recuced by 1 when the difference angle is greater than 180 degrees. ADVANTAGE - Accurate recording of number of axis rotations.

Patent DE-4002123-A1 (DE)
Inventor: HAGENKOETTER MANFRED PROF DR D
IPC: F02M25/00
Filed: 1990-01-25
Abstract: A process and a device for recovering hydrocarbons from a gas-air mixture operates in the following manner: first the gas-air mixture is cooled and caused to condense. The hydrocarbons still remaining in the gas-air mixture after condensation are burned in an internal combustion engine. The power thus generated by the engine is used to operate the cooling installation used for the cooling and condensation processes. The cooling installation is so designed and run that the gas-air mixture is cleansed as far as possible of hydrocarbons and impurities on passing through the installation. Fuel is metered into the gas-air mixture downstream of the cooling installation and upstream of the internal combustion engine.

Title: Prodn. of extruded foam section - feeds foaming mixt. into plastic film which is folded over and welded into tube, allows mixt. to expand, and passes tube to forming tools
Inventor: ZIMMERMANN KARL
IPC: B29C44/30
Filed: 1990-03-06
Abstract: Extruded sections are produced from fire-protective foam by using a liq reactive mix. A flexible tube is filled with the mix which is allowed to foam up in the absence of air whilst a set quantity of the material plus the tube is drawn into a foaming chamber; the material is then formed into the section in the tube whilst still plastic. The process can utilise rollers which are pref made of foam, rubber or other elastic material. A tube (3) feed foaming mix into a strip of film (1) which is folded over to form a tube with overlapping edges; the tube (3) extends through the stage (7) where the edges are welded together and through the cbmpressing point of two rollers (8). These rollers (8) can have semi-circular grooves. A cord, wire, cable or similar can also be fed into the centre of the foaming space. The inner tube (3) ends in the expansion reaction space (15), where two rollers (16) restrain the volumetric expansion to the desired extent by adjusting the gap between the rollers. While the foaming reaction proceeds, the material passes through a forming tool (21) of two parts (22, 23) and of suitable length for the speed of the moving prod. These parts (22, 23) can be heated or cooled as required. Finally the prod is drawn off by traction rollers (27, 28). ADVANTAGE - The process produces the sections free of any large occlusions and with low wt. The prods are universally applicable for a variety of purposes in the fire protection field.
