Abstract: A method of degassing cavitation fluid using a closed-loop cavitation fluid circulatory system is provided. The procedure is comprised of multiple stages. During the first stage, the cavitation fluid is continuously circulated through the cavitation chamber, reservoir and the circulatory system while the fluid within the chamber is cavitated. A vacuum system coupled to the fluid reservoir periodically degasses the fluid. During the second stage, pumping of the cavitation fluid through the chamber is discontinued. Gases released by the cavitation process are periodically pumped out of the chamber and periodically eliminated by the vacuum system. A third stage, although not required, can be used to further eliminate gases dissolved within the cavitation fluid. During the third stage cavities are formed within the cavitation fluid within the chamber using any of a variety of means such as neutron bombardment, laser vaporization or localized heating.

Abstract: A method of reducing power to an electron emitting cathode comprises the steps of sensing a weather condition; calculating a condition number based upon the weather condition; comparing the condition number to a threshold; and reducing the power to the electron emitting cathode when the condition number is greater than the threshold. The apparatus and method may be implemented upon a system having a high voltage power source, an RF tube, a control processor, and a signal processor.

Abstract: A method of assembling multiple port assemblies in a cavitation chamber is provided. The method is comprised of boring at least two ports of different sizes in a cavitation chamber wall of the cavitation chamber. The external port diameter of the smaller port is smaller than that port's internal port diameter. A member selected from the group consisting of windows, plugs, feed-throughs, sensors, transducers and couplers is inserted into the chamber through the larger port and positioned within the smaller port. The member can be secured within the smaller port with an adhesive. A mounting ring/retaining ring, retaining coupler or port cover seals the second, larger port. A second member selected from the group consisting of windows, plugs, feed-throughs, sensors, transducers and couplers can be positioned within a cone-shaped port within the mounting ring or retaining coupler. A feed-thru, sensor, transducer or coupler can be integrated into the port cover.

Abstract: A flood control system including panels made from plastic sheeting adhered to a frame and stacked one on top of the other. The panels are held in position by a series of columns, each of the columns having an H-shaped cross section that provides for and defines panel receiving slot adapted and arranged to interact with gaskets on the panels to provide a water tight barrier.
