Abstract: A fire hydrant valve removal tool has a torque multiplier at the top end, a torque stabilizing bushing which keeps the transmission of torque straight from the top of the hydrant above ground to the valve in the bottom of the hydrant underground, a hydrant mounting adapter which at the lower end matches the flanges and holes of the hydrant so that the valve removal too may be bolted directly to the hydrant for stability, a drive which fits over the hydrant stem all the way down to the valve, and improved valve keys having a conical internal section allowing easy fitting over the hydrant stem. In addition the present invention teaches a rescue key which is designed to easily slide down into the valve body itself and apply torque to the guides/blades of the valve itself.

Abstract: A rotating magnetron sputtering cathode apparatus comprising a radio frequency power supply, a power delivery assembly, a cylindrical rotating cathode, a shaft and a drive motor, wherein the power delivery assembly comprises a magnetic field source positioned within the cathode and an electrode extending within said cathode to transmit radio frequency energy to target material on the outer surface of the cathode. The electrode is electrically isolated from the shaft, and is formed from non-ferrous materials, and the shaft is mechanically connected to the cathode such that they remain electrically isolated while the cathode rotates about the magnetic field source and a portion of the electrode. The power supply is adapted to supply radio frequency energy at frequencies of 1 MHz or higher and is electrically connected to the electrode.
