Patent DE-2143960-A1 (DE)
Title: Arc hard facing - with strip electrode and loose powder
Inventor: ARNOLDY ROMAN FRANCIS
IPC: B23K9/04
Filed: 1971-09-02
Abstract: The facing is carried out with an arc welding head, a consumable strip electrode being fed adjustably into the arc zone at the same time as a granular alloyed metal powder, the weight ratio of the powder to the electrode strip being 1:1 to 3:1. The welding head is run at an adjustable speed parallel to the workpiece surface. The method yields a uniform weld bead. No excessive arc concentration is required thereby reducing the tendency of the metal base to melt and mix with the facing material and also reducing warping. The method permits also faster welding.
Patent DE-2158376-A1 (DE)
Title: Blown tube optically examined - continuously without contact before being flattened
Inventor: NOETZEL WOLFRAM DR
IPC: G02B27/54
Filed: 1971-11-25
Abstract: A method for continuously, automatically examining a plastics tube to detect inhomogeneities is as follows: the tube after leaving the cooling ring of the extruder passes without contact perpendicularly to the line through the diaphragms of an optical detector between two symmetrically arranged lenses; the light beam passing through the apparatus is projected onto a screen and converted into electrical signals which are continuously recorded. The method enables point-type faults such as "fish-eyes" to be detected in preference to longitudinal streaks, while the tube is still in its blown state before being flattened into a sheet.
