Coolable Window System
US Patent:
2004024, Dec 2, 2004
Filed:
May 10, 2004
Appl. No.:
10/842362
Inventors:
Robert Parsells - Princeton NJ, US
Charles Gentile - Plainsboro NJ, US
Charles Gentile - Plainsboro NJ, US
Assignee:
Princeton University - Princeton NJ
International Classification:
H01S003/04, H01S003/08, G01F023/00
US Classification:
372/103000, 372/036000
Abstract:
The present invention is directed toward a window or foil that transmits incident radiation with high efficiency and that is coupled to a cooling means to dissipate heat from radiation losses occurring within the window. In one aspect the invention provides an energy-transmitting system that includes a nonmetallic window and means for cooling the window. In a second aspect the invention provides a laser assembly including a laser cavity enclosed by a wall that has one or more surfaces, wherein at least one surface includes an actively cooled window of the invention. In various embodiments of both the energy-transmitting system and the laser assembly the window includes a dielectric material, or a semiconducting material such as silicon. In addition a corrosion-resistant coating may be deposited on at least one surface of the window. Among several modalities for cooling the window, favorably the window includes a semiconductor exhibiting a thermoelectric effect and the cooling means implements thermoelectric cooling thereof. The invention additionally provides a method of cooling a window, such as when it is included as part of a laser assembly described herein, that includes providing the assembly and operating a cooling means disposed effectively to cool the window.
Method And Apparatus For Diamond Wire Cutting Of Metal Structures
US Patent:
2004023, Nov 25, 2004
Filed:
May 3, 2002
Appl. No.:
10/138792
Inventors:
Robert Parsells - Princeton NJ, US
Geoff Gettelfinger - Princeton Junction NJ, US

International Classification:
B28D001/08
US Classification:
125/021000
Abstract:
A method and apparatus for diamond wire cutting of metal structures, such as nuclear reactor vessels, is provided. A diamond wire saw having a plurality of diamond beads with beveled or chamfered edges is provided for sawing into the walls of the metal structure. The diamond wire is guided by a plurality of support structures allowing for a multitude of different cuts. The diamond wire is cleaned and cooled by COduring the cutting process to prevent breakage of the wire and provide efficient cutting. Concrete can be provided within the metal structure to enhance cutting efficiency and reduce airborne contaminants. The invention can be remotely controlled to reduce exposure of workers to radioactivity and other hazards.
