US Patent:

45889651, May 13, 1986

Filed:

Jun 25, 1984

Appl. No.:

6/623896

Inventors:

Alfred W. Cook - Andover MA

Assignee:

Varian Associates, Inc. - Palo Alto CA

International Classification:

H03B 910

US Classification:

331 91

Abstract:

A coaxial magnetron has a high-Q resonant cavity surrounding a multiple-resonator anode circuit and coupled by slots to alternate anode resonators. The cavity is resonant in the TE. sub. 111 mode, having two zero points of electric field on its periphery. The anode circuit is correspondingly resonant in its N/2-1 mode. Mode suppression means damp out the degenerate TE. sub. 111 mode which is not coupled to the output iris. The size and weight of the magnetron are much less than conventional tubes using a cavity resonant in the TE. sub. 011 mode with circular electric field.

Assignee:

Varian Associates - Palo Alto CA

International Classification:

H01J 2550

US Classification:

315 3951

Abstract:

A permanent magnet structure particularly beneficial for generating the interaction field in coaxial, crossed field electron tubes is designed such that the normal iron flux return path is not required. Substantial reduction in weight results. A further benefit is that a magnetron interaction structure including the magnets may be built as a unit replaceable in the field in a stabilizing cavity structure. Since the cavity structure contains no iron, the magnets are not demagnetized in the replacement process and there are no mechanical mounting problems caused by magnetic forces.

International Classification:

H05K 7/20
H05K 7/14

Abstract:

A data center having a hot aisle, a cold aisle, a row of server rack cabinets located between the cold aisle and the hot aisle, and a self-expanding gap filler located in a gap between adjacent elements in the data center is provided. The self-expanding gap filler includes a compressible material and an outer layer having an outer surface and an inner surface, the inner surface defining an inner space, the outer layer encapsulating the compressible material within the inner space. The compressible material is configured to expand from a compressed state within the inner space of the outer layer to an expanded state within the inner space of the outer layer in response to a seal being at least partially released within the outer layer to allow air to flow into the inner space of the outer layer, whereby the self-expanding gap filler at least partially fills the gap between the adjacent elements in the data center.

International Classification:

H05K 7/20
H05K 7/14

Abstract:

A method of at least partially filling a gap between adjacent elements in a data center having a hot aisle and a cold aisle to decrease air leakage between the hot aisle and the cold aisle through the gap is provided. The method includes providing a gap filler having a compressible material and an outer layer having an outer surface and an inner surface. The inner surface defines a sealed inner space and the outer layer encapsulates the compressible material in a compressed state within the inner space. The method also includes placing the gap filler in the gap between the adjacent elements in the data center and at least partially releasing a seal within the outer layer to allow air to flow into the inner space of the outer layer to permit the compressible material to expand from the compressed state within the inner space of the outer layer to an expanded state within the inner space of the outer layer, thereby at least partially filling the gap between the adjacent elements in the data center.
