  • Patent number: 4453463
    Abstract: An inker for a lithographic printing press in which ink and dampening fluid are applied to the printing plate by a resilient applicator roller. A resilient ink metering member having a flat metering surface is mounted on a support member which is movable to adjust the angle of intersection of the metering surface relative to a plane tangent to the roller surface. A doctor blade is mounted to remove dampening fluid from the roller surface and is actuated to an operative position upon actuation of the dampener to apply dampening fluid to the applicator roller.

  • Patent number: 4448412
    Abstract: An exercising device comprising a frame, actuating means, and a double acting hydraulic cylinder used therewith. The hydraulic cylinder includes a container having first and second chambers and passageways for placing the chambers in fluid communication with one another. A piston is slideably mounted within the first chamber and valve means are mounted with the container for preventing fluid communication into the first chamber when the piston is moved in a first direction and for preventing fluid communication around the piston when the piston is moved in a second direction. A piston rod extends into the container for moving the piston in response to movement of the actuating means. A control means governs the fluid flow through a selected passageway from the first to the second chamber to regulate the amount of force necessary to move the actuating means during exercise of a portion of the body.

  • Patent number: 4441708
    Abstract: A leg exercising device having a general frame having an L-shaped seat for supporting the body and a pair of leg gripping frames pivotally secured to the general frame such that the axis of rotation of the leg gripping frames are aligned with the pivot point of the knee of the user. The leg gripping frames have resilient pads which allow the leg to pass therethrough such that the leg is padded from the frame as it moves in both directions. A power cylinder is pivotally secured between the general frame and each of the leg gripping frames about the axis of rotation in both directions. Each of the leg gripping frames may be moved independently of each other.

  • Patent number: 4420985
    Abstract: A force measurement device including one or more beams (21) to which tension strain gages (101 and 104) and compression strain gages (102 and 103) are secured. The strain gages are connected in a Wheatstone bridge circuit (FIG. 3) to deliver an output signal related to the magnitude of force supported by the beams. Each of the beams (21) has rigid flange portions (22 and 23) to permit welding (37) ends of the beams to supports (38) and load receiving members (40) at points far removed from the neutral axis (x--x) of each beam to minimize influence of welding on beam deflection.
