Abstract: A mechanical override is provided for use with electromechanical linear actuators used in the control of lever operated valves. A pair of telescoping tubes are supported in a fixed relationship to the valve. One tube provides a mounting location for the linear actuator while the other tube is stationary. A lead screw will be manually rotated to move one tube relative to the other. The linear actuator will travel with the moving tube to adjust the valve position.

Abstract: A motor vehicle has an enclosed battery storage compartment with a door separating the compartment from an adjacent support surface that has been roughened to reduce slippage of persons stepping thereon. A battery holder has a mounting base in the compartment and a battery cell support tray mounted on wheels for rolling between a position on top of the mounting base, where the battery cells are housed, and a position on the surface, where the battery cells are inspected and serviced. Mounted to the tray is a handle having a horizontally extending grip portion for grasping to move the handle or tray and a vertical projecting lock portion for engaging a keeper, mounted on the mounting base, to lock the tray in a stationary position. When the handle is in a tray locking position, the grip portion of the handle extends adjacent the tray and the compartment door can be closed, retaining the handle in its locked position.
