Patent number: 4629902Abstract: A device for measuring web tension of a continually movable web transported on a rotated cylindrical roller of a printing machine includes two eccentrics connected to two ends of the roller for supporting the latter for rotation and each includng a supporting pin. The supporting pin of one of the eccentrics has its end rigidly connected to a machine frame and is able to twist proportionally to the web tension. A lever having one end rigidly connected to the twistable supporting pin has its other end positioned between a light transmitter and a light detector of an optoelectronic sensor which detects the amount of twisting of the supporting pin.Type: GrantFiled: April 18, 1985Date of Patent: December 16, 1986Assignee: Veb Kombinant Polygraph "Werner Lamberz" LeipzigInventors: Dietrich Hank, Kerstin Hauer, Friedrich Richter

Patent number: 4572324Abstract: An ear piece for a sound producing device such as a headset comprises an annular ear cushion with at least one part of an elastic, soft, sound permeable foam and at least one other part of a sound permeable layer which is thin in relation to the overall thickness of the air cushion and has a defined acoustic impedance for low and medium frequencies of the audibility range. The ear cushion acts as a frictional resistance with a central portion defining coupling space from the sound producing device to the ear and representing an acoustic connection through the sound producing device to the air.Type: GrantFiled: May 10, 1984Date of Patent: February 25, 1986Assignee: AKG Akustische u.Kino-Gerate Gesellschaft mbHInventors: Werner Fidi, Friedrich Richter

Patent number: 4146947Abstract: A spreader roll for webs of textile material has a flexible shaft whose end portions rotate in or with pairs of bearings installed in sleeves which are pivotable about horizontal axes to thereby change the curvature of the shaft and/or slidable with respect to stationary holders to thereby effect or change lateral deflection of the shaft. The shaft is surrounded by and fixed to annular supporting elements which are surrounded by an elastic hose whose ends are sealed against entry of atmospheric air.Type: GrantFiled: July 14, 1977Date of Patent: April 3, 1979Assignee: Hermann Windel GmbH & Co.Inventor: Friedrich Richter

Patent number: 4074064Abstract: A gas-insulated, high-voltage apparatus wherein arcs can develop includes an encapsulation and at least one electrical conductor made of aluminum or an alloy thereof which is held in spaced relation to the encapsulation by insulators. A surface is arranged at the conductor at locations thereof subject to the greatest arc activity. The surface faces the encapsulation and is defined by an electrically conductive, arc-resistant material. An excessive stress and endangerment of the encapsulation because of arc action is thereby prevented.Type: GrantFiled: November 19, 1974Date of Patent: February 14, 1978Assignee: Siemens AktiengesellschaftInventors: Kurt Muller, Friedrich Richter, Heinz-Helmut Schramm
