Patent number: 8872057Abstract: An electrode of an inductive output tube (IOT) is provided with channels for guiding cooling fluid. In one aspect of the invention, the channels are in a confronting relationship with a jacket surrounding the electrode and spaced from the electrode so as to define an interior region. Cooling fluid such as oil is circulated in the channels in fluid communication with the interior region, providing an escape mechanism for trapped bubbles in order to prevent localized heating of the electrode. In another aspect of the invention, the channels form multiple intersecting helical patterns of different pitches, with the steeper-pitched channels providing a more direct escape route for the bubbles.Type: GrantFiled: March 15, 2006Date of Patent: October 28, 2014Assignee: Communications & Power Industries LLCInventors: Paul A. Krzeminski, Gordon R. Lavering

Publication number: 20070080762Abstract: An inductive output tube (IOT) operates in a frequency range above 1000 MHz. An output window may be provided to separate a vacuum portion of the IOT from an atmospheric pressure portion of the IOT, the output window being surrounded by a cooling air manifold, the manifold including an air input port and a plurality of apertures permitting cooling air to move from the port, through the manifold and into the atmospheric pressure portion of the IOT. The output cavity may include a liquid coolant input port; a lower circular coolant channel coupled to receive liquid coolant from the liquid coolant input port; a vertical coolant channel coupled to receive liquid coolant from the lower circular coolant channel; an upper circular coolant channel coupled to receive liquid coolant from the vertical coolant channel; and a liquid coolant exhaust port coupled to receive liquid coolant from the upper circular coolant channel.Type: ApplicationFiled: December 4, 2006Publication date: April 12, 2007Applicant: Communications & Power Industries, Inc.Inventors: Heinz Bohlen, Yanxia Li, Paul Krzeminski, Edmund Davies, Robert Tornoe

Publication number: 20060154504Abstract: A self-guiding cover assembly for a vacuum electron device (VED) enclosure has a cover, a pair of guide plates, and a pair of guide elements. The cover has a top, a sidewall, an inside and an outside, and at least one electrical connector disposed on the inside of the cover for mating with a VED. The pair of guide plates is disposed on opposite sides of the outside of the sidewall of the cover. The guide plates each have a track. The pair of guide elements is mounted on opposite sides of the outside of the sidewall of the cover. The pair of guide elements each mates with the track. The cover further comprises a breach lock mechanism for seating the VED into the VED enclosure having a base. The breach lock mechanism has guide elements mounted on the VED. A first sleeve is mounted on the base and removably receives the VED. A second sleeve is mounted on the base and removably receives the first sleeve. The second sleeve has tracks for mating with the guide elements.Type: ApplicationFiled: March 7, 2006Publication date: July 13, 2006Inventors: Wilson Toy, Christopher Yates, Paul Krzeminski, Robert Tornoe, Edmund Davies

Publication number: 20040222744Abstract: An electrode structure for a vacuum tube is formed by having a ceramic insulating body act as the tube wall. Electrode areas are formed on the inside of the tube by coating the inside of the tube wall with a conductor. These electrode areas are then coupled, as necessary, to external electronic circuits. The coupling may be performed by through-wall connections, metallized abutting connections and other conventional means. The ceramic insulating body may be generally cylindrical in shape and may be formed of a material such as aluminum nitride, beryllium oxide, aluminum oxide and the like.Type: ApplicationFiled: November 19, 2003Publication date: November 11, 2004Applicant: Communications & Power Industries, Inc.,Inventors: Robert Tornoe, Yanxia Li, Paul A.
