Title: Galvanic process operation using pre- and post-treatment baths - involves continuously or cyclically supplying fresh liq. whose life is limited by continuous operation
Inventor: DOMOGALLA SIEGFRIED
IPC: C25D21/14
Filed: 1990-05-11
Abstract: Operation of galvanic treatment installation with at least a pre- and post-treatment bath, involves the novelty of continuously or cyclically supplying fresh treatment liquid to one or other of the baths whose service life is limited by continuous operation of the unit.

Title: Spinning frame - has roving supply changeover mechanism which incorporates various devices
Inventor: BRENNWALDER DANIEL
IPC: D01H15/00
Filed: 1990-12-18
Abstract: The roving supply to a spinning frame proceeds through a change-over mechanism, so that an initial supply on coming to an end is taken over by the reserve supply. Both are joined together and fed through automatically. By means of the mechanism the initial supply is held until the joint is made, and the trailing end removed at the same time as the new reserve is clipped to one side. ADVANTAGE - The mechanism is compact and efficient. Various functions are incorporated in one entity. The roving is held on the base plate as it passes into the funnel and the end process which may be a drafting zone of a ring-spinning frame, or a rotor unit. At the entrance to the mechanism are three guide plates with hooked noses with the purpose of selecting a direction for an initial roving or a reserve and subsequent supplies. Two pads with curved faces rest on the base plate. Under the nose of the pad the reserve roving is held by the gripper. Each of the parts of the mechanism are centred on a shaft with connecting levers separated by a spiral spring. The levers are also spring held, and are positioned when actuated by an electromagnetic device. A controller synchronises the movements.

Title: Electromechanical compensation balance with mass-spring-damper system - derives compensation signal from weighing pan deflection with and without article to be weighed
Inventor: BECKER WOLF-JUERGEN PROF DR
IPC: G01G7/04
Filed: 1990-12-31

Inventor: HALLING HORST
IPC: G01N23/083
Filed: 1991-03-30
Abstract: The invention relates to a device for irradiating layers of bides with X-rays in which a target (2) switched as an anode acts as the X-ray source and which has a detector (6) to measure the reduction in the intensity of the X-ray beam after penetrating the object (1).
