Abstract: A system for determining structural characteristics of an electromagnetic energy shielding material during a manufacturing process includes a transmitting antenna device mounted for a reciprocal linear movement across a width thereof, the transmitting antenna device being connected to a source of the electromagnetic energy and operable to transmit waves of the electromagnetic energy through the thickness of the electromagnetic energy shielding material during the reciprocal linear movement. A receiving antenna device is also mounted for the reciprocal linear movement in an alignment with the transmitting antenna device and operable to receive, during the reciprocal linear movement, the waves of electromagnetic energy being absorbed and attenuated by the electromagnetic energy shielding material.

Abstract: A cable trough cover assembly and method of assembly including a cover plate and a hinge piece. The cover plate includes a pivot member along at least one edge, and the hinge piece defines a pocket for releasably receiving the pivot member. The pocket and pivot member arrangement allow the cover plate to be rotated relative to a cable trough to which the hinge pieces may be mounted.

Abstract: A flow switch for a high pressure washing system or other flow-related system is disclosed. The flow switch switches from an open to a closed position in the presence of adequate flow in a water or other fluid-carrying pipe. The flow switch includes a cartridge body, a sensor, a plunger, a magnet, and a spring. The cartridge body has an inlet port and an outlet port which allows fluid to flow into the cartridge body, through a flow chamber, and out of the cartridge body. The cartridge body also has a sensor chamber for accommodating the sensor. The sensor is positioned within the sensor chamber and is used to determine whether fluid is flowing through the flow chamber. A plunger is positioned within the flow chamber, and is responsive to fluid flow. Between the plunger and the sensor is a spring. The spring prevents the plunger from coming in close proximity to the sensor absent fluid flow.

Abstract: A system and method for recovering energy from compressed air. The system and method a microprocessor based control module to monitor compressor discharge pressure and determine the need to bypass gas. Excess compressed air is bypassed to an energy recovery system that converts the potential energy of the compressed air into electrical or mechanical energy. Generated electrical power may be returned to the main power grid or used to power auxiliary equipment, such as the compressor's oil pump.
