Appl. No.:

09/545563

Inventors:

Raymond J. Meilunas - Hampton Bays NY
Gregory P. Dillon - Commack NY
Jerrell A. Nardiello - Hicksville NY

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

B30B 1506

US Classification:

156382, 156510, 156563, 156581, 1565833, 156213, 156267, 156285, 425112, 425175

Abstract:

In one form of the present invention, a system for constructing a laminate ( ) is disclosed. The system comprises a ply feeder ( ) that sequentially stacks one or more plies ( ) to form a ply stack ( ). A computer ( ) directs a laser ( ) to cut each ply ( ) to a desired shape after becoming part of the ply stack ( ). The ply stack ( ) is then placed on a reconfigurable tool ( ). An applied pressure compresses the ply stack ( ) against the reconfigurable tool ( ) while an actuator ( ) subsequently reconfigures the reconfigurable tool pins ( ) to a predetermined shape. In a more particular embodiment, a composites forming process is used, such as diaphragm forming, to compress the ply stack ( ) before the reconfigurable tool pins ( ) are reconfigured. In another particular embodiment, the reconfigurable tool pins ( ) are first reconfigured then a vacuum diaphragm forming process is utilized to compress the ply stack ( ) against the reconfigurable tool ( ).

International Classification:

H01J 35/08
G01N 23/04

US Classification:

378143, 378 57

Abstract:

Diamond based proton beam target () designs for use in contraband detection/indentification systems. Such novel Diamond based proton beam targets () are used in Electrostatic and RF Accelerator based devices for generating proton beams () that impinge on the targets () for generating single or multiple monoenergetic gamma ray () beams used in detection/measurement of contraband.

International Classification:

B29C 47/00

US Classification:

264465, 26421117

Abstract:

A method for fabrication of an optical transparency, that includes electrospinning of an Indium Tin Oxide sol polymer solution such that nanofibers are formed, heat treating the electrospun nanofibers such that the Indium Tin Oxide is in a conductive form, and dispersing the heat treated nanofibers into a substantially optically clear polymer.

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

G21G 400

US Classification:

378119

Abstract:

In accordance with the present invention, there is provided a proton beam target for generating gamma rays which are generated therefrom in response to an impinging proton beam. The proton beam target is provided with a. sup. 13 C gamma reaction layer for generating the gamma rays therefrom. The proton beam target is further provided with a stopping layer for mitigating transmission of the proton beam therethrough. The stopping layer is formed of a refractory metal which is hydrogen soluble for dissolving implanted hydrogen molecules therewithin as a result of the impingement of the proton beam and which is chemically reactive with the. sup. 13 C gamma reaction layer for chemically bonding therewith.
