Patent DE-2457509-A1 (DE)
Title: Rotary offset printing machine web treatment - web wetted differentially in accordance with quantity of ink to be applied
Inventor: FISCHER HERMANN
IPC: B41F23/02
Filed: 1974-12-05
Abstract: In a rotary off-set printing machine the web is moistened ahead of the first printing unit and the moistening is done differentially so that portions due to receive large ink areas receive more moisture. The moisture is applied by spray devices arranged across the width of the web and controlled by manually adjustable valves (20) so that the moisture distribution across the web can be regulated. The valves may be controlled selectively by cams (25, 26) so that moisture can be applied in accordance with the pattern repeat of the print. The spray devices may be centrifugal throw devices.

Title: Automatic adjustment for disc brakes - has brake piston with spring loaded guide sleeve controlling free movement
Inventor: MEIER ERNST
IPC: F16D65/54
Filed: 1975-02-12
Abstract: There is an adjustment mechanism inside the brake piston (3) consisting of an adjustment rod fixed to the housing and a friction ring(10). The ring is supported by a spring (13) on one side and an internal intermediate sleeve (12) on the other. The spring fits round a guide sleeve (6) and the axial clearance is less than that of the brake lining itself. In this way the free movement of the piston is controlled. The piston (3) and guide sleeve (6) locate in one another by means of opposed lugs (4, 5). Their length is approximately double the play that can be allowed between the piston and guide sleeve. The lugs can be rotated by rotating the piston. This causes them to fit on top of one another rather than interlock.

Title: Pneumatic sorting drum for small components - has grooves around inside, with tangential air feed and component discharge holes
Inventor: MACKEBRANDT HORST
IPC: B65G47/14
Filed: 1975-09-25
Abstract: A pneumatic sorting drum for feed of small components such as springs, has a feed opening one end, and a set of parallel grooves (10) around the inside.

Title: Contactless thermal fixer for photocopier - uses heated gas stream provided by electric heating elements or flame
Inventor: TURINI GERHARD
IPC: G03G15/20
Filed: 1976-03-26
Abstract: The toner image on the copy sheet is thermally fixed by melting it into the paper. A heated air stream is passed over the surface of the paper in a controlled way to melt the toner without having any heating rollers etc. touching the paper. This eliminates smearing from the rollers. The airstream can be generated by a recirculating system with a blower (22) and heating elements (20). A simpler setup has flame produced hot air blasts which are directed over the surface of the paper, with the flames set far enough away from the paper to prevent charring. The system allows faster heat control with improved warmup times.
