Abstract: A cathode electrode of copper-based material adapted for use in an electrical device is provided with a deposit of silver coated with a finely divided electrically conductive material such as graphite palladium or platinum. The silver deposit is formed by reacting a dilute solution of sodium-silver cyanide with the copper-based cathode electrode. When utilized in an electrolytic capacitor, the cathode electrode helps to increase the capacitance of the cathode electrode and the contact of the copper-based material to an acid electrolyte is uniformly distributed over a large area to provide extended operation with high ripple current with deep cycles of charge and discharge.

Abstract: A workman's lift platform apparatus has a vertically swingable and extensible boom with a workman's platform at the outer end. A color coding indicating the amount of boom extension is provided on the fly section of the boom, visible to the workman in the platform, and an indicator plate having corresponding color coding is provided adjacent the controls on the platform. The indicator plate in the form of a drum is driven proportionately to the angular movement of the boom by a pair of sheathed, push-pull cables, or by a sheathed torsion cable. In other embodiments, the indicator plate is tilted in proportion to the angular movement of the boom by a sheathed push-pull cable or by a parallel bar linkage. A cursor is provided adjacent the indicator plate, and is part of a gravity-operated pendulum.

Abstract: Controls for an aerial lift platform apparatus which has a steerable mobile chassis, a rotatable upper works, and an extensible boom pivoted on the upper works for luffing movement. The controls are grouped to provide a first group of control members in physical proximity to each other for controlling upper works movement and a second group of control members for controlling movement of the chassis. Each of these control members is mounted for movement substantially to simulate the movement which is controlled. A third group of control members is for controlling the engine, and are in physical proximity to each other. The control members are mounted on a control console having near-horizontal and near-vertical surfaces from which the control members extend, the vehicle control member for drive and steering extending upwardly from the near-horizontal surface.
