An extension cord (2) has an electrical cord (6) with an asymmetrical cross section (8) and one or more modular sockets (4). The electrical cord has a plurality of electrical conductors (12) extending throughout its length and a plug at one end. The modular socket can be attached anywhere along the length of the electrical cord. The modular socket has two parts (18, 20) forming an opening (44) which houses the cord, the opening being of substantially the same effective asymmetrical cross section as the cord. When the modular socket is fastened to the cord, spikes (24) in the modular socket pierce the cord's insulating material (26) and contact the conductors running through the cord. The spikes electrically connect the cord's conductors with the plug's electrical contacts (16). The asymmetrical cross section ensures proper polarity for the modular socket.

A high pressure fluid valve includes a tubular portion with a valve seat on its end and a closure element for engaging the valve seat. A piston carries either the tubular portion or the closure element as a movable valve member, with the other being fixed. A first fluid chamber is provided adjacent the valve seat and a second fluid chamber is spaced therefrom adjacent the other end of the movable valve member. When the movable valve member is actuated, one of the fluid chambers increases in volume by the same amount that the other decreases in volume, thereby maintaining the internal volume of the valve constant.

A solar concentrator is disclosed herein and includes a modularized point focusing solar concentrating panel which is movably mounted to track the sun. This panel has an overall parabolic reflecting surface and a triangular or approximately triangular configuration which improves structural integrity, minimizes wind resistance and permits rapid and easy stowing.
