Abstract: A light conductor has two sealed embedding elements molded to its ends, respectively containing a light emitter and a light receiver. The light emitter is connected to a likewise embedded Wiegand probe, the light receiver is connected to a likewise embedded amplifier and a pulse shaper. These signal transmission lines are used for data acquisition, the respective Wiegand probes are disposed to be responsive to measured conditions represented by variable magnetic fields. The transmission system is moisture-proof and insensitive to interfering electromagnetic radiation.

Abstract: The PC-boards are contained in sealed enclosures, and serially effective heat pipe systems conduct thermal energy from the respective sources of development (e.g., power transmitters) to the top and from there to a heat pump system. Stacking such units and operating the heat transfer partially in parallel is disclosed.

Abstract: The invention comprises a machine for the continuous processing of leather hides using a table board which is fed lengthways through at least one pair of processing tools lying parallel and opposite to each other. The leather hide to be processed is placed with its middle part around the front edge of a table board. The machine includes means for displacing with respect to the table board, the unprocessed middle strip of hide on the front edge of the table board, to permit it to be processed.

Abstract: A machine for processing flat, flexible articles, such as leather, to soften them. The machine utilizes a pair of opposed undulating surfaced processing members having an advance and return movement superimposed on an up and down movement. The opposed processing members are disposed on each side of the article to be processed, and soften the article, as well as move the article along between the processing members.
