| 126 | Hydrostatic sidestick coupling | US09616479 | 2000-07-14 | US06572055B1 | 2003-06-03 | Guy Bernard |
| In a system for directing the motion of a vehicle, controllers, each of which independently controls motion of the vehicle, are linked to a coupling assembly to cause the controllers to experience substantially identical motion. The coupling assembly includes one or more fluid displacers that are linked to a first vehicle controller which force fluid from a first chamber, through a conduit, into a second chamber and against one or more fluid displacers that are linked to a second vehicle controller. The coupling assembly may be used to control motion of the aircraft in multiple degrees of freedom. | ||||||
| 127 | Drive device for a movable part, especially a mold closure device for an injection molding machine, and method for operating such a drive device | US10152311 | 2002-05-20 | US20030029325A1 | 2003-02-13 | Jorg Dantlgraber |
| The invention is based on a drive device for a movable part, especially a mold closure device for an injection molding machine. A conventional mold closure device possesses a hydraulic cylinder-and-piston unit having a first hydraulic piston, which borders with a first active surface on a first pressure chamber and with a second active surface, which is smaller than the first active surface and faces in the opposite direction thereto, on a second pressure chamber, and comprises a further hydraulic piston, which is fixedly connected to the first hydraulic piston, and possesses a third active surface, which borders on a third pressure chamber and is active in the same direction as the second active surface. Via a valve arrangement, the second pressure chamber can be connected to the first pressure chamber and can be relieved of pressure separately from the first pressure chamber. In the conventional mold closure device, the cylinder-and-piston unit for closing and opening the mold is operated in open hydraulic circuits, the pressure chambers being connected to a tank at the end of the closure operation and at the end of the opening operation and the movable part evidently being braked only by friction. It is an object of the invention further to develop a drive device of the conventional type so that it can be operated at higher dynamics. This is achieved in that a second hydraulic cylinder-and-piston unit is present, having a second hydraulic piston which is movable relative to the cylinder by a drive motor, especially an electric drive motor, and borders with a fourth active surface on a fourth pressure chamber, which is permanently connected to the third pressure chamber, and with a fifth active surface, which faces in the opposite direction to the fourth active surface, borders on a fifth pressure chamber, which can be connected to the first pressure chamber, and wherein the dimensional relationship between the fifth active surface and the difference between the first active surface and the second active surface is equal to the dimensional relationship between the fourth active surface and the third active surface. In a drive device according to the invention, a pressure which brakes the movable part builds up in the first pressure chamber and in the second pressure chamber or third pressure chamber when the second hydraulic piston is no longer moving, without a valve having to be actuated for that purpose. | ||||||

| 129 | Fully implantable bone expansion device | US157595 | 1998-09-21 | US6106525A | 2000-08-22 | Hans Sachse |
| This invention describes a bone lengthening device, which is fully implantable and works on a cylinder and piston basis which is driven with micro-hydraulics or a internal threaded rod. Choosing a profile which is not round, torsion of the cylinder and piston assembly is avoided, and expansion can be achieved both in a linear as well as in a circular fashion. Since this device is fully implantable, common disadvantages with current methods of bone expansion can be eliminated. | ||||||

| 137 | Hydraulic control with feedback for powered machinery | US799695 | 1977-05-23 | US4122678A | 1978-10-31 | Mahlon T. Wilson |
| A three-cylinder hydraulic system providing position feedback for controlling powered machinery is described wherein an operator moves a control handle and the various working elements of the machinery respond to follow the path of the control handle, the freedom of movement of which is limited by the ability of the machinery to respond. The system consists of a control station comprised of an assemblage of linkages resembling the machinery to be controlled. Associated with each movable element on both the control station and machine, and with each lever or switch on the machine, are double-acting hydraulic cylinders or rotary actuators. The three cylinders thereby associated with each particular working element and its actuation are connected hydraulically so that the control station cylinder hydraulically manipulates the cylinder that moves the lever or switch that actuates that working element on the machine. The cylinder on that working element on the machine in turn hydraulically manipulates both the control station cylinder and the cylinder that moves the lever or switch. The control station may be located either upon the machinery or at a position remote from the machinery. | ||||||
