Abstract: A roll tarp system with a rear assembly including a pivoting arm and cable to help deploy the roll tarp system. The pivoting arm and flexible cable can articulate to allow a rear door to open. The roll tarp system includes a conventional roll tarp on a roller attached to one side of a container of a truck or trailer and an actuator to operate the tarp. A pivoting arm can be attached to the outside of a rear opening door on the container. A flexible cable has one end attached to the distal end of the pivoting arm and another end attached to the tarp axle of the roller of the roll tarp. Preferably, the flexible cable consists of the only structure between a cable attachment at the pivoting arm and an attachment at the axle of the roller.

Abstract: A mounting fixture for a power plant nozzle which allows the user to perform a single set-up and alignment on a nozzle location for overlay, matching, and inspection technologies. Once the fixture is set-up, the user can mount and dismount welding, machining, and inspection equipment in less time than traditional motion systems would require.

Abstract: The invention relates to a method of signal analysis that determines the location of a transmitter and to devices that implement the method. The method includes receiving by at least three receivers, from a transmitter, a first continuous-time signal having a first channel. The first channel includes a first plurality of signal carriers having known relative initial phases and having known frequencies which are periodically spaced and which are orthogonal to one another within a first frequency range. The signal analysis method also includes determining the phase shifts of the carriers of the first channel resulting from the distance the carriers traveled in reaching the first receiver. Analysis of the phase shifts yields time difference of arrival information amongst the receivers, which is further processed to determine the location of the transmitter.

Abstract: The present invention changes the known use of a weld pad and allows the weld pad to be deposited while the existing nozzle is not defective and remains in place so when the nozzle becomes defective a new pressure boundary weld is used only when required resulting in minimized utility downtime.
