Patent DE-3937926-A1 (DE)
Inventor: KALLWEIT MANFRED
IPC: C25D5/00
Filed: 1989-11-15
Abstract: In known devices for reducing the concentration of field lines in an electroplating plant for treating disk-shaped workpieces, a diaphragm is associated with a lower end region of a workpiece.

The invention relates to a diaphragm device (6) with one or more diaphragms (7) which are associated with one of the faces of the anode (1) facing the workpiece (2) such that the concentration of field lines (4) between the anode (1) and the workpiece (2) can be reduced, completely or partly, in a predetermined manner.
Patent DE-3938480-A1 (DE)
Inventor: BALZEIT RALF
IPC: H04N1/04
Filed: 1989-11-20
Abstract: The invention relates to a device for clamping film material in sheets to the recording drum of a reproduction arrangement and the method of operation of said device. The recording drum (1) has axially directed rows (6) of suction apertures for securing the image substrate (22) by a vacuum. In the walls (8) of the recording drum (1) there are suction channels (7), each interconnecting the suction apertures (5) of one row (6). In the recording drum (1) is arranged a vacuum distributor (25; 26; 27; 29) controllable by the rotary movement of the drum (1) which selectively connects the individual suction channels (7) or the appropriate rows (6) of suction apertures to a fixed vacuum pump (13). The vacuum distributor (25; 26; 27; 29) can be controlled in such a way that, during the clamping process, first of all the vacuum is applied to those rows of suction holes on which the leading region of the recording substrate (22) lies. This produces a high initial vacuum so that the recording substrate does not slip. Thereafter further rows (7) of suction apertures are connected in accordance with the greater extent to which the recording substrate is wound on the rotating recording drum (1) and vacuum is applied to them. The actuation of further rows (7) of suction apertures depending on the peripheral length of the recording substrate (22) is terminated at that row (7) on which the end region of the substrate (22) lies. The device especially makes it possible to clamp and secure large-size recording substrates on the recording drum (1) without creasing and slip.

Patent DE-4002230-A1 (DE)
Inventor: PUESCHMANN MANFRED
IPC: D01H1/08
Filed: 1990-01-26
Abstract: A method of forming and drawing off a package (3) of partially twisted thread within a centrifugal spindle (1) uses a guide tube (2). The package is built up from the vicinity of the bottom (5) of the spindle in the direction of the opposite aperture (6) with the speeds of the basic traverse movement (h1) being the same in both directions and the speed being minimised so that the layers of thread are deposited virtually parallel with one another.
