Title: Sheet fed offset printer - has blanket cylinder with gripper groove featuring flat chamfers to compensate blanket swells
Inventor: FISCHER HERMANN
IPC: B41F30/04
Filed: 1976-03-31
Abstract: The lower loading of gripper in the sheet-fed offset printer is achieved by grinding flat chamfers in the gripper groove of the blanket cylinder. This compensates for the unavoidable swells in the blanket which is not made of relatively stiff plastic-base material. As a result, the press can run smoothly, and the print does not exhibit stripes or other defects. The blanket cylinder (2) operates with plate cylinder (3) carrying the printing form plate (10), and with impression cylinder (1). The groove (6) for the gripper is kept to the minimum size possible and its edges exhibit a flat chamfer made by grinding. The chamfer runs at an angle of 5 deg. to the tangent of the cylinder surface, while the width of the flat amounts to a double thickness of the blanket.

Title: Rotating cylinder block type hydraulic pump - has automatic volume control operated by discharge pressure for constant output
Inventor: WINTER KLAUS
IPC: F04B1/04
Filed: 1976-04-05
Abstract: The pump has a rotating cylinder block (3) which has radial cylinders (4) containing reciprocating pistons (5). The outer ends of the pistons run on a guide ring (12) which is eccentric to the cylinder block and thus produces the reciprocating motion. A stationary shaft (1) inside the cylinder block has inlet and outlet ports which serve the cylinders. The crescent shaped space (16) between the block and the guide ring is divided into separate chambers by the pistons and forms a second pumping zone. Liquid discharged by this zone is admitted to one side (23) of the outside of the guide ring which it tends to displace transversely against the force of a spring (25) on the other side. This automatically maintains the pumping rate constant.
