  • Patent number: 7191646
    Abstract: A flow meter includes a meter body defining a cavity having opposing ends joined by opposed sides at corners. At least one of the corners is recessed to form a reservoir. A box frame defining a frame interior is received in the cavity for reciprocal movement between the cavity ends. A sliding block defining a circular cavity is received in the frame interior for reciprocal movement therein said frame interior. A valve disc is received in the circular cavity for rotational movement therein. The valve disc includes an eccentric hole formed therethrough. A shaft extending through the eccentric hole is rotatably fixed to the valve disc. Fluid flowing through the flow meter reciprocally moves the box frame and sliding block to rotate the valve disc and the shaft.

  • Patent number: 5018431
    Abstract: An apparatus for positioning a work implement in predetermined operative attitudes, including a valve body mounting a piston which is operable for movement through a range of selective operative positions, and which is further connected to the work implement; a pair of pulse valves mounted on the valve body and connected in fluid communication with the piston and operable selectively to supply a source of hydraulic pressure to the valve body; and an actuator is connected in signal transmitting relation to the pair of pulse valves and is adapted selectively to actuate same thereby causing the selective release of hydraulic pressure to position the piston, and thus the work implement in a selected operable attitude.
