Abstract: A landmine-neutralization system has a vehicle including a water supply tank and an electrical power supply and an electro-discharge apparatus. The electro-discharge apparatus includes one or more electro-discharge nozzles each having a discharge chamber that has an inlet for receiving water from the water supply tank and an outlet, a first electrode extending into the discharge chamber and being electrically connected to one or more high-voltage capacitors that are connected to, and chargeable by, the electrical power supply, a second electrode proximate to the first electrode to define a gap between the first and second electrodes and a switch to cause the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes through one or more exit orifices of the one or more nozzles ahead of the plasma bubble to thereby neutralize a landmine.

Abstract: A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.

Abstract: A method of stripping, prepping and coating a surface comprises first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.
