Patent DE-4226780-A1 (DE)
Inventor: LINDNER BERND
IPC: B41F27/00
Filed: 1992-08-13
Abstract: A device for checking the in-register positioning of a printing plate on the plate cylinder (1) of printing machines has, in the tension rail (3, 4) for receiving this printing plate, measuring sensors, by means of which the in-register position can be detected in the form of electrically interrogatable signals. So that these signals can be interrogated directly by machine control, for example in conjunction with an automatic or manual printing-plate feed, contact faces are mounted in the region of the tension rail. These contact faces are assigned sensing heads (29, 30) which are mounted on the frame movably relative to the plate cylinder and which can be pressed against these very contact faces after a corresponding angular positioning of the plate cylinder. During the introduction of a new printing plate, therefore, an evaluation unit for receiving the signals is connected to the measuring sensors. <IMAGE>

Title: Gas-filled spring element without damping
Inventor: KLOTZ DETLEF
IPC: B25D9/12
Filed: 1993-01-18
Abstract: In pneumatic springs, due to their type of construction with piston and sliding-surface seal, leakage losses and pressure reductions caused by this occur in the course of time in the face of frequent load reversals. To increase the service life and the possible number of load reversals, an improved spring element without damping is to be created. The novel spring element (1) comprises a pot-shaped hollow cylinder (2) which is filled with gas and is hermetically sealed by a diaphragm (3). On its side remote from the pressure, the diaphragm (3) is firmly connected to a rod (8) which is mounted in a longitudinally displaceable manner in a flange bushing (4) on the hollow cylinder (2). The manufacturing costs of the spring element are low, because neither high surface quality nor accuracy of fit are necessary. Different sizes of stroke can be realised through the use of different styles of diaphragm. The spring element is preferably suitable for use where rapid load reversals occur, for example in percussion mechanisms of drilling machines and hammer drills. <IMAGE>

Title: Clamping device for at least one winding tube or the like to be fixed on a shank
Inventor: GRIMM HANS DR ING
IPC: B65H75/24
Filed: 1993-10-15
Abstract: The subject of the invention is a clamping device for at least one winding tube to be fixed on a shank, preferably for a plurality of winding tubes, tube portions, rolls or the like to be fixed next to one another. Radially extendable clamping jaws (6) serve for clamping and are actuated via wedge surfaces by means of push elements (9) movable longitudinally within the shank. The push elements (9) themselves are displaced by spindle nuts (13) which are in threaded engagement with a threaded rod (12) running centrally in the shank. Each spindle nut is in frictional engagement with a box nut (15) engaging over it, so that, when a predetermined torque is exceeded, the spindle nut (13) rotates together with the threaded rod (12) and does not move the clamping jaws (6) any further outwards. In this way, all the clamping jaws come to bear on the core of the tube or the like with a reproducible pretensioning force. <IMAGE>
