Abstract:

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 an electrical connector on 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 guide elements are mounted on the enclosure on opposite sides of the cover. The pair of guide elements each mates with the track to guide the cover as it is lifted from the enclosure. The cover further comprises a breach lock mechanism for seating the VED into the VED enclosure having the cover and a base. The breach lock mechanism has guide elements mounted on the cover. A sleeve is mounted on the base and removably receives the cover with the VED.

International Classification:

H05K 7/15

US Classification:

361725, 361815

Abstract:

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 at least one electrical connector () disposed on the inside thereof 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 () which guides the guide elements () mounted on the cover such that the cover is constrained in its motion when opening or closing in order to avoid damaging the connectors to the VED. The cover further comprises a breach lock mechanism for seating the VED into the VED enclosure by rotation of a sleeve (). The cover () defines first () and second () chambers separated by a panel. The top of the VED protrudes into the first chamber through an adapter plate having hole for passage of the VED there through.

US Classification:

439314

Abstract:

A self-guiding cover assembly for a vacuum electron device (VED) enclosure has a breach lock mechanism for seating the VED into the VED enclosure having a base. The breach lock mechanism has a plurality of guide elements mounted on the VED, a first sleeve mounted on the base and configured to removably receive the VED, and a second sleeve mounted on the base and configured to removably receive the first sleeve and rotate around the first sleeve. The first sleeve has a plurality of vertical slots configured to mate with the plurality of guide elements. The second sleeve has tracks configured to mate with the guide elements. A rotation of the second sleeve pulls the VED into the base for seating the VED.

International Classification:

H01J025/34

US Classification:

315/003500

Abstract:

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.

International Classification:

H05H 13/00

US Classification:

315502000

Abstract:

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.

International Classification:

H01J 902

US Classification:

445 50

Abstract:

The invention is a method of manufacture of a cylndrical electrode such as a thermionic cathode comprising an array of helical filaments. The method comprises the step of placing the array, attached to its support electrodes which are fixedly mounted to a common subassembly support, inside a close-fitting refractory dielectric cylinder and heating the filament assembly by passing current through the filaments. The filament assembly expands to contact the form. On further heating it is plastically deformed to form a perfect cylindrical shape. After cooling and shrinking, it is removed from the form.
