121 | Actuator Assembly | US11569993 | 2005-06-08 | US20080006030A1 | 2008-01-10 | Nigel Fox |
An actuator assembly (1) comprises a body (2) in which works an actuating piston (7), a first piston (5) and at least one second piston (6), a chamber (26) containing a substantially incompressible fluid by which each of the first and second pistons (5, 6) acts on the actuating piston (7). The movement of the first piston (5) from a retracted position to an extended position acts via the fluid to cause the actuating piston (7) to move from a retracted position to an operational position, and subsequent movement of a second piston (6) from a retracted position to an extended position acts via the fluid to cause an actuation movement of the actuating piston (7). | ||||||
122 | Mechanical lift measurement system | US10549716 | 2004-03-26 | US20070034420A1 | 2007-02-15 | Frantz Stanford |
A lift measurement system is provided for determining a position of a load during a lift operation. The system includes a display that includes a scale and encloses a movable indicator that moves relative to the scale. A linkage is in communication with the load and the scale, such that movement of the load is translated to movement of the indicator relative to the scale to provide an indication of the position of the load. A plurality of displays and linkages may be installed at various load support zones such that the relative position of the corresponding indicators provides feedback related to the orientation of the load. | ||||||
123 | Hydraulic drive system | US11291753 | 2005-12-01 | US20060156713A1 | 2006-07-20 | George Kadlicko |
A hydraulic drive system for an actuator uses a pair of pressure compensated hydraulic machines to control flow to and from the drive chambers of the actuator by varying the controlled pressure of one of the machines. The machines are mechanically coupled to permit energy recovery and charge an accumulator to store supplies energy. The drive system may be combined with other services including a transmission for incorporation in a vehicle. The transmission uses a pressure compensated supply and torque control of the wheels. | ||||||
124 | Multi-stroke cylinder | US10718556 | 2003-11-24 | US06962103B2 | 2005-11-08 | William C. Sandlin |

The multi-stroke cylinder utilizes a plurality of mechanically linked pneumatic or hydraulic pistons having different stroke lengths that can be added together in any combination, allowing the user to select any stroke length up to a predetermined, total combined stroke length, in increments equal to the stroke length of the smallest cylinder. The multi-stroke cylinder includes a head assembly having a fluid inlet for introducing fluid to the cylinder at a first pressure. The cylinder also includes a first positioning system having a plurality of pistons capable of moving a piston rod away from the first positioning system, and a second positioning system located between the head assembly and the first positioning system.

129 | 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. | ||||||
