Abstract: An acceleration sensitive automotive shock absorber includes an improved compression head assembly. Within a cup inside the head, a biased mass slides relative to a pin joined to the cup, to open a unique path of fluid flow during accelerating compression of the shock absorber.

Abstract: A shock absorber including a piston assembly dividing a cylinder into a rebound chamber and a compression chamber, the piston assembly including fluid control bleed orifices of a size to permit flow therethrough during a relatively slow long amplitude movement of the piston assembly in either direction, normally closed valves for controlling the flow of fluid between the chambers during relatively fast long amplitude movements of the piston assembly, and a normally open valve assembly operable (1) to permit relatively unrestricted flow of hydraulic fluid between the chambers during a relatively rapid short amplitude movement of the piston assembly in either direction and (2) to move into a closed position (a) during a relatively slow long amplitude movement of the piston assembly in either direction so as to permit the bleed orifices to control the resultant fluid movement between the chambers and (b) during a relatively rapid long amplitude movement so as to permit the normally closed valves to control the r

Abstract: A spray-type dampening apparatus for lighographic printing presses comprises a resilient surfaced, fluid supply roller that is partially immersed in a reservoir of dampening fluid and a coacting, hard surfaced feed roller having generally longitudinally disposed grooves in the peripheral surface thereof and forming a nip with the supply roller. The supply roller is rotated at a surface speed sufficient to advance and maintain a supply of dampening fluid from the reservoir to the said nip whereas the feed roller is rotated at a high surface speed relative to the supply roller to thereby generate and project a fine mist of the dampening fluid from the nip toward an adjacent transfer roller.

Abstract: The invention pertains to an improved transfer roller for use in continuous type dampening mechanisms for lithographic offset printing presses. The surface of the transfer roller is provided with minute, closely spaced, spiral grooves whereby the fluid feed capacity of such dampeners is significantly increased so as to satisfy the dampening requirements of high speed lithographic web presses.
