  • Patent number: 6431049
    Abstract: A double acting actuator is used for operating a pair of latches, and is controlled through a manifold that will permit a base end of the actuator to remain under pressure, and accommodate valve and piston leakage by connecting the rod end of the actuator to drain through a small orifice. The manifold additionally has relief valves for providing different pressures for the rod and base ends of the actuator, and a flow divider that provides a low flow to the actuator while the main flow from a pump is used for other hydraulic components.

  • Patent number: 4352079
    Abstract: A high voltage transformer is formed by a unitary core mounting a primary winding being inserted in a cavity of a bobbin that mounts the secondary winding. The secondary winding is placed in alternate bays of a multibay structure to isolate the windings from one another to avoid high potential breakdown. The assembly is complete by the mounting of the core within the cavity of the bobbin, but can be supplemented by covering the entire unit with a protective housing that further aids in mounting the transformer to an insulating surface, such as a printed wiring board.
