Patent DE-2735894-A1 (DE)
Inventor: SIGG HANS
IPC: B24B49/04
Filed: 1977-08-09
Abstract: Prior to the finish-grinding in size-controlled grinding operations, workpieces and grinding machine are often relieved of pressure by briefly lifting the grinding wheel away from the workpiece. The grinding wheel is then fed once again at a very low rate which corresponds to the finish-grinding, as a result of which the machining time is substantially lengthened. In order to shorten this time, the invention proposes to carry out the renewed feed of the grinding wheel at a relatively high rate and only to change over to a low rate corresponding to the finish-grinding when the grinding wheel makes contact with the workpiece. The control device used for this purpose comprises a supplementary device to establish the point at which the grinding wheel makes contact with the workpiece, this emitting a corresponding signal to change over the rate of feed.

Title: Automatic measurement of surface tension and wetting angle - using optical measurement of drop or bubble illuminated by parallel light
Inventor: GEISER GEORG DR ING
IPC: G01N13/02
Filed: 1979-03-15
Abstract: Drops or air bubbles of the fluid are illuminated by a parallel beam of light. The intensity of the light reflected back from a background mirror is measured at different positions and the results are processed electronically to compute the surface tension and wetting angle. The computation uses a binary intensity signal generated by passing the direct measurements through a comparator. The level of the comparator threshold is adapted for each set of measurements. Full information is obtained by using both suspended and resting drops or bubbles. The technique is superior to conventional capillary action in that it readily permits automation.
