Patent DE-2810079-A1 (DE)
Title: Electroless plating of bundles of loose fibres - esp. carbon or graphite fibres used to make electric contact brushes for electric motors
Inventor: SCHMIDT OTTO
IPC: C23C18/16
Filed: 1978-03-08
Abstract: In the parent patent individual fibres are coated in loose fibre bundles suspended from a tank so an electroless plating soln. can flow down the fibres. Improvement is that the plating process is repeatedly interrupted after specific coating periods; and during the interruption, the fibres in each bundle are displaced slightly w.r.t. each other. The displacement is pref. achieved via an elastic roll pressing the loose bundles against a stationary plate; directly after the displacement more plating soln. is fed down the fibres, esp. via an overhead tank through which the soln. is circulated via a pump. Process ensures the uniform coating of all the fibres in the bundles, which may be cut into short brushes, so a uniform coating is essential.

Patent DE-2838705-A1 (DE)
Inventor: HOEFELMAYR TILMAN DIPL KFM DR
IPC: A01J5/04
Filed: 1978-09-05
Abstract: A collecting piece incorporating a pair of relatively movable members which function as a valve to control the supply of a vacuum to all four milking cups of a quarter milking machine while maintaining the milk supplied from each of the milking cups separate from one another. Each of the lines connected to each of the pair of movable members of the connecting piece terminate in an opening which is flush with a sliding surface on each of the two relatively movable members. Thus, rotating one of the members relative to the other will either bring the openings into alignment with each other or cause the openings to remain out of alignment with each other. If desired, a locking mechanism can be provided for locking the two relatively movable members in the two positions thereof.

Patent DE-2847982-A1 (DE)
Inventor: WIRZ WALTER
IPC: B27N1/02
Filed: 1978-11-04
Abstract: The continuous mixer comprises a drum (1) which can be rotated about a tilted axis and whose shell (2) on its inside has entrainment means (11). These gradually convey the particles (33) fed in at the input side, situated at a higher level, of the drum (1) in the direction of a closed drum bottom (3). In order to achieve a relatively light construction, the drum bottom is rigidly connected, firstly, to the drum shell (2) and secondly to a driven shaft (6). The particles (33), which in each case are conveyed upwards by the entrainment means and, when they fall down and traverse the drum interior, are sprayed with binder, can escape after the treatment through orifices of the drum shell (2). Said orifices are arranged in the immediate vicinity of the drum bottom (3) and permit easy removal of the treated particles. <IMAGE>
