Abstract: A portable, switchable electric extension outlet having a manually actuable switch which is remote from the outlet enclosure and is connected to the enclosure by a remote control cord, other than the outlet's power cord. The enclosure end of the remote control cord is connected to an electrical circuit in the enclosure which connects an electrical power source to receptacles mounted to the enclosure. The manually actuable switch alternatively completes or breaks the electrical circuit's connection between the power source and the receptacles.

Abstract: Internal seals including gaskets and the like of a hydraulic and other enclosed fluid systems can be conditioned with an ester composition desirably an acetate ester. The composition can be combined with a system's fluid, or used itself as a system fluid alone or in combination with other additives. Conditioning includes softening said internal seals and gaskets so they are more effective at sealing.
