Patent number: 7073258Abstract: A method of constructing a port assembly for use with a single piece cavitation chamber, typically a spherical chamber, is provided. The port assembly includes a cone-shaped port, a cone-shaped mounting ring and a central member mounted within the mounting ring. The mounting ring is located within the chamber prior to the final assembly of the chamber itself, i.e., at a time in which the chamber is comprised of multiple pieces. After the final assembly of the chamber is complete, a central member such as a window, plug, gas feed-thru, liquid feed-thru, mechanical feed-thru or sensor assembly is placed within the chamber. The mounting ring is then pulled into place within the cone-shaped port, followed by the central member. To expedite assembly, specialized tools can be used to pull the mounting ring and the central member into place.Type: GrantFiled: September 7, 2004Date of Patent: July 11, 2006Assignee: Impulse Devices, Inc.Inventors: Ross Alan Tessien, Dario Felipe Gaitan, Daniel A.

Patent number: 7057328Abstract: An acoustic driver assembly for use with a spherical cavitation chamber is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass, coupled together with a centrally located threaded means (e.g., all thread, bolt, etc.). The driver assembly is either attached to the exterior surface of the spherical cavitation chamber with the same threaded means, a different threaded means, or a more permanent coupling means such as brazing, diffusion bonding or epoxy. In at least one embodiment, the transducer is comprised of a pair of piezo-electric transducers, preferably with the adjacent surfaces of the piezo-electric transducers having the same polarity. The surface of the head mass that is adjacent to the external surface of the chamber has a spherical curvature greater than the spherical curvature of the external surface of the chamber, thus providing a ring of contact between the acoustic driver and the cavitation chamber.Type: GrantFiled: March 21, 2005Date of Patent: June 6, 2006Assignee: Impulse Devices, Inc.Inventors: Ross Alan Tessien, Dario Felipe Gaitan, Daniel A.

Patent number: 7049730Abstract: An acoustic driver assembly for use with a spherical cavitation chamber is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass, coupled together with a centrally located threaded means (e.g., all thread, bolt, etc.). The head mass of the driver assembly is permanently attached to the exterior surface of the spherical cavitation chamber via brazing or diffusion bonding. In at least one embodiment, the transducer is comprised of a pair of piezo-electric transducers, preferably with the adjacent surfaces of the piezo-electric transducers having the same polarity. The surface of the head mass that is adjacent to the external surface of the chamber has a spherical curvature equivalent to the spherical curvature of the external surface of the chamber, thus providing maximum coupling efficiency between the acoustic driver and the cavitation chamber.Type: GrantFiled: March 11, 2005Date of Patent: May 23, 2006Assignee: Impulse Devices, Inc.Inventors: Ross Alan Tessien, Dario Felipe Gaitan, Daniel A.
