Patent DE-2423571-A1 (DE)
Title: Screwdriver with centralising and tensioning device - has head to hold screw mounted against housing via plate spring
Inventor: WEBER KARL-HEINZ
IPC: B25B21/00
Filed: 1974-05-15
Abstract: The design can be used for hand or machine operated screwdrivers. The screw head is held so that it cannot turn in the housing and the tensioning sleeve fits in the screw head. The advantage of the design is that slight misalignment between screw and screwdriver is permissible. The part of the screw head that holds the tensioning sleeve is mounted so that a small amount of pivoting is possible in any direction. This is achieved by a plate spring ring fitting between an extension to the screw head and the supporting socket. A peg fits radially through the outer socket to prevent the head extension turning relative to the main housing.

Title: Round manhole cover gas tight seal - is expanded against hole sides by clamping cover halves together
Inventor: SPITZER ARTUR
IPC: F16J13/06
Filed: 1975-04-29
Abstract: The round manhole cover gastight seal is for use where the cover bears against a flange round the hole on the non-pressurised side of the tank etc, to which it is secured at points round the periphery. A sealing ring fits between flange and cover edge, and is tightened by a hand control.

Title: Roller wiper for rotary photogravure printer - performs defined concentric movement about contact point of blade to plate cylinder
Inventor: BRILL BERNHARDT DR
IPC: B41F9/10
Filed: 1975-05-30
Abstract: Rotary photogravure printing machine has a wiper blade (2) which removes ink from the surface of the machines plate cylinder (1). To ensure that blade wear arising from frictional forces is uniform and involves limited wiper loading, the wiper can execute a defined concentric movement about its point of contact whereby this angle of movement amounts to 20 deg. In this way in every position of the wiper it only rests on the plate cylinder surface at a constant narrow working chamfer (5). The loading applied to the wiper is minimised by this means and hence its service life is increased.
