| 130 | Hydraulic circuit with selectively actuated motor | US12387685 | 2009-05-06 | US08276376B2 | 2012-10-02 | Keith M. Mears; James E. Smith; Brad A. Meyerholtz |
| A hydraulic circuit for a vehicle having at least one selectively actuated hydraulic assist motor. The hydraulic circuit includes a first loop that includes, in serial order, a first hydraulic pump, a first hydraulic line, at least one hydraulic motor and a second hydraulic line. A second hydraulic pump and a third valve is used to control the flow of low pressure fluid from the second pump to the hydraulic motor casing. The low pressure fluid through the third valve maintains the motor pistons retracted when the motor is not being used. For actuating the motor, the third valve is actuated for disconnecting the second pump and relieving pressure from the motor casing. Low pressure is then provided to the first and second lines for extending the motor pistons. The first and second valves are then actuated for isolating the first and second lines from one another, and the first pump is used to power the motor. The first, second and third valves are advantageously solenoid cartridge valves. | ||||||

| 137 | Manipulator usable for a glass electrode or the like | US761802 | 1985-08-02 | US4679976A | 1987-07-14 | Eiichi Narishige; Shinji Yoneyama |
| An improved manipulator for manipulating a glass electrode or the like is disclosed. The manipulator includes a driving section and an actuating section with the glass electrode mounted thereon both of which are in operative association with one another by way of three lines of tubes. The X-coordinate, Y-coordinate and Z-coordinate driving mechanisms in the driving section are hydraulically communicated with the X-coordinate, Y-coordinate and Z-coordinate displacing mechanisms in the actuating section. As a tiltable lever with the Z-coordinate driving mechanism incorporated therein is inclined, hydraulic pressure in the X-Y coordinate plane driving mechanism constituted by the combination of X-coordinate and Y-coordinate rectilinear driving mechanisms varies and thus developed pressure variations are transmitted to the X-coordinate and Y-coordinate displacing mechanisms in the actuating section whereby the glass electrode is displaced by a distance equivalent to an angle of inclining movement of the tiltable lever in both the directions of X-coordinate and Y-coordinate. Displacing of the glass electrode in the direction of Z-coordinate is effected by rotating the knob on the tiltable lever. Water having a thermal expansion coefficient smaller than oil is used as hydraulic medium for each of the hydraulic cylinders. | ||||||
