Title: Depth control when etchhigg iin ad magnesium - device completes an electric circuit when sample plate has dissolved
Inventor: HITZE WERNER
IPC: C23F1/08
Filed: 1973-05-21
Abstract: In etching these metals, a Zn or Mg plate with the same thickness as the required depth of etch is inserted in the bath and is arranged so that when it dissolves an electric circuit is completed. A weighted contact is used to overcome bad electric connections, thus giving accurate, reliable process control in single-stage etching. A tube passes through the lid of the etching tank, the top of the tube being connected to an electric bell; the second bell connection goes to the insulated top of a weighted push-rod which can slide up and down the tube. The bottom of the rod rests on the test plate and, when this plate has dissolved, the push-rod drops, thus completing the electric circuit. A simple spring clip holds the test plate in position.

Title: Selector/switch arrangement for HV-step-transformer - has two housings to improve surge voltage and short-cct. current strength
Inventor: HEINZ RUDOLF
IPC: H01F29/02
Filed: 1973-09-07
Abstract: The location arrangement of pre-selector, selector, load transfer switch and switch-over resistor for HV-step-transformers is so chosen that the selector is split up into two housings, one for the even numbered and the other for the odd numbered steps. The two selector housings are placed side by side in the same plane with the pre-selector switch in between them. In a second plane, preferably above the first plane are the load switch and the switch-over resistor located. These five construction elements form one unit which is attached to a fork bracket which projects from the actual transformer casing. The switch-over resistor may have its own container which may be accessible through a mounting hole in the transformer cover plate. The arrangement is space saving and secures an increased surge voltage strength and an improved short-circuit current strength.
