Patent number: 8122898Abstract: A rotating and telescoping cleaning system improves high pressure water cleaning of the inner surfaces of vessels or tanks. Vessels can be vertically divided with dividing plates with centered through-holes. Synchronized and controlled transverse and rotary movements of water jets result in a controlled spiral or helical cleaning track along the vessel walls. The water jets are directed at a pre-adjusted distance from the vessel wall and the travel speed of the water nozzle jets is exactly controlled allowing the removal of very hard deposits. One pass with the tool carrier with operating water jets along the length axis of the vessel results in a thoroughly cleaned vessel wall. The tool unfolds and folds inside of the vessel powered by the flow of the high pressure cleaning water.Type: GrantFiled: June 4, 2009Date of Patent: February 28, 2012Assignee: Aquajet Ltd.Inventors: Christian Geppert, Stefan Schroth

Patent number: 6539952Abstract: The invention provides an apparatus and method for cleaning or etching wafers. The invention further provides a megasonic transducer designed to apply mechanical vibrations to a layer of fluid in contact with a wafer. The electromechanical transducer is housed in a quartz or sapphire lens which is chemically compatible with the layer of fluid, and sealed to protect the housing interior from fluids and chemical fumes. An electrical power source produces a signal that is sent to the transducer to generate a megasonic wave. The wave travels between the lens and the wafer, through the layer of fluid, dislodging small particles from the wafer which are then removed in the fluid stream. In one embodiment of the present invention, a wafer to be cleaned is placed on a rotatable support below a transducer assembly. A fluid is introduced through the transducer assembly to provide a layer of fluid between the lens and wafer.Type: GrantFiled: April 24, 2001Date of Patent: April 1, 2003Assignee: Solid State Equipment Corp.Inventor: Herman Itzkowitz
