Abstract: A method comprising forming a mesoporous conductive layer and depositing a capacitive material within pores of the mesoporous conductive layer through a thickness of the mesoporous conductive layer. The mesoporous conductive layer may be formed by physical deposition or electrodeposition of gold, platinum or titanium, and the capacitive material may be Ru, Ni, Fe, Co, Ir or Mn, yielding a mesoporous electrode. Two such electrodes may be assembled using a solid electrolyte, yielding an all-solid-state supercapacitor. The mesoporous conductive layer may be deposited on a substrate provided with an interdigitated electrode resin mask, and the resin mask removed after depositing the capacitive material within pores of the mesoporous conductive layer, to yield interdigitated electrodes.

Abstract: A counterweight installation and removal apparatus for a truck-mounted crane includes a counterweight having a bottom surface, a plurality of rollers attached to either the bottom surface of the counterweight or to a crane carrier deck, and at least one inclined surface positioned on the other of the bottom surface of the counterweight or the crane carrier deck to engage the plurality of rollers when the counterweight is installed and removed.

Abstract: A control system for a liftcrane powered by a closed loop hydraulic system. In a liftcrane that includes controls by which an operator can run the liftcrane and mechanical subsystems each powered by a closed loop hydraulic system having a pump and an actuator, the present invention provides a controller responsive to the controls and connected to the mechanical subsystems, and further in which the controller is capable of running a routine for controlling said mechanical subsystems to define operation of the liftcrane.

Abstract: A quick disconnect system for a piece of construction equipment having an upper works rotatably mounted on a lower works, such as a crane, is disclosed. The system includes an adapter plate to which preferably the upper works is releasably connected, such as by pinned links. The adapter plate and preferably the lower works may then be maintained as a unit with a swing bearing therebetween even when the upper works is removed for easy transportation of the equipment. When used with a conventional swing bearing, having an inner race and an outer race, the inner race may be bolted to the lower works and the outer race may be bolted to the adapter plate.
