Patent DE-4101150-A1 (DE)
Title: Two-stage grinding process for robotic applications - involves using two side-by-side mounted wheels stepping across surface to rough and finish grind
Inventor: POPP PETER DR SC TECHN
IPC: B24B27/033
Filed: 1991-01-14
Abstract: In a typical robotic application a motor (9) drives two-side-by-side mounted grinding wheels (1, 4) through a right-angle drive 910). The axes of movement of the robot are a horizontal traverse X, a cross-feed Y and a downfeed Z. The outer wheel (1) is a laminar or flap type for removing rust or scale, and the slightly samller inner wheel is of a conventional type for finishing. A first pass is taken down the work with the flap wheel to remove rust and scale. The unit is then fed across in the Y direction so that a second neighbouring strip can be ground with the flap wheel. Int he next pass the second strip is rough ground while at the same time the inner grinding wheel finishes the frist strip. The process is continued step by step to cover the whole surface. ADVANTAGE - Reduces need for manual intervention and wheel changes. Greater productivity.

Patent DE-4127593-A1 (DE)
Inventor: LEVACHER FRIEDRICH KARL DR
IPC: G02B6/44
Filed: 1991-08-21
Abstract: An optical fibre cable, in which at least one optical fibre is inserted with excess length into a tube made from metal or plastic and a protective sheath is applied around the tube, is to be constructed such that it is possible to use it to locate a heat source with a high accuracy of location. The solution consists essentially in that the optical fibre (which is coated with a thermostable material) serving as temperature sensor (TS) is spiralled as narrowly as possible, so that the permissible radius of curvature is not undershot. The optical fibre spiral is fixed by winding the optical fibre with a defined length of lay (s) about a dimensionally stable, flexible, round core (K) which has a defined radius (r). The main field of application is fire monitoring in the trunkings of underground, fast suburban or municipal railways and in mining. <IMAGE>

Patent DE-4141993-A1 (DE)
Inventor: HERRMANN KURT
IPC: B01D17/02
Filed: 1991-12-19
Abstract: The invention concerns a method and device for treating oil/water emulsions (3) using ultrafiltration, the emulsion being drawn by a feed pump (2) out of a circulating tank (1), fed to an ultrafiltration unit (6) where filtrate is removed, and then passed back to the tank (1). The aim of the invention is to carry out the ultrafiltration so that separation of the oil/water emulsion (3) is more complete, i.e. the emulsion is separated more cleanly into its constituents. This is achieved by passing fine bubbles of gas continuously or at periodic intervals into the stream of liquid after it has left the feed pump (2), using an aeration unit (5) fitted in the feed line and controlled by means of a pressure-adjustment device. After separation of the filtrate in the ultrafiltration unit (6), the stream of liquid is allowed to stand at atmospheric pressure in a relaxation tank associated with the circulating tank (1).
