Abstract: A charger plug release system for use with an electric vehicle is provided. The charger plug release system provides a preloaded outward force to the electric charging plug when the plug is electrically connected to a charging receptacle on the EV. When charging is completed, the plug may be released (e.g., via a mobile “app”), and the outward force applied by the system to the plug causes the plug to be ejected without manual intervention. Accordingly, the release system eliminates the need for the user to manually pull the plug from the EV charging receptacle, and instead, forcefully ejects the plug from the EV automatically. This allows the user to automatically remove the plug from the EV from within the vehicle or from another safe location.

Abstract: This invention effects a significant reduction in leakage along a piston reciprocating in a cylinder and having a high fluid pressure differential existing between one end of the piston and the other. A large number of closely spaced, annular grooves are provided on the periphery of the piston and the clearance between the non-grooved piston diameter and the interior wall of the cylinder is maintained at a value significantly larger than that commonly employed between a smooth cylindrical shaft and a cylindrical interior sealing surface. The employment of such unexpectedly large clearance not only provides reduced fluid leakage for lighter density fluids when the equipment is relatively new, but the leakage becomes substantially less than that encountered in a smooth surface bearing construction as the piston and cylinder surfaces wear and increase the clearance.

Abstract: A fluid delivery system is disclosed utilizing a high pressure cleaning fluid, such as a blast of high pressure water, to remove material from the inside wall of the stator of a relatively large electric motor. In the preferred embodiment of this invention illustrated, the fluid delivery system includes a nozzle carriage having a high pressure nozzle movable along the length of the inside wall of the stator to be cleaned, a rotating carriage frame for rotating the nozzle about the inside wall of the stator to be cleaned, a vertically movable wall upon which the rotating carriage frame is mounted, and a base frame or skid on which the vertically moving wall is mounted. The nozzle can be positioned to move along a desired longitudinal path along the inside of the stator, such as along longitudinal grooves where the material to be removed is located.
