US Patent:

8028826, Oct 4, 2011

Filed:

Jan 29, 2010

Appl. No.:

12/696265

Inventors:

Timothy Woo - Flushing NY, US
Leon Moy - Flushing NY, US
Alan N. Cohen - Wharton NJ, US
Daniel Lee Prillaman - Flushing NY, US
Christina Morales - Mine Hill NJ, US

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F42B 39/00

US Classification:

206 3, 206589, 206593, 224931

Abstract:

An improved 25 mm linked cartridge IM ammunition storage system, using existing ammunition cans, that simplifies the design of the storage system, and utilizes standoffs to separate the base of each cartridge from the ends of the ammunition can—thereby allowing the cartridges base IM venting system to vent properly, avoiding pressure build-up, and reducing the risk of explosion or detonation of the propellant.

Appl. No.:

13/487688

Inventors:

Timothy Woo - Flushing NY, US
Leon Moy - Montclair NJ, US

Christina Morales - Mine Hill NJ, US

International Classification:

F42B 39/20

US Classification:

102430, 102481

Abstract:

An IM type steel cartridge whose base contains a central bore there through—within which bore is a steel base plug holding a primer cup, the base plug being held in place by a low melt, 220 to 250 degree F. melt eutectic solder—wherein, if the cartridge is subjected to an unforeseen thermal or kinetic event, the solder will melt, the base plug ejected, and the propellant will vent rather than explode. The solder bond between the base plug and the cartridge case within which it is held is capable of resisting the from about 72,000, to up to 90,000 psi, force generated within the firing chamber of the weapon by the ignition and firing of the cartridge.

Appl. No.:

9/676278

Inventors:

Maryellen Lavin - Hightstown NJ

Jack E. Hurst - D-51368 Leverkusen, DE

International Classification:

B01J 2906

US Classification:

502 68

Abstract:

Difluoromethane (R-32) is of current interest as a partial replacement for chlorodifluoromethane (R-22) refrigerant heretofore widely used in vapor compression refrigeration systems. R-32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The potassium cation form of a zeolite A molecular sieve--with at least 60 percent of the sodium cations replaced with potassium ions, agglomerated with a clay binder, and pore-reduced to essentially exclude the adsorption of R-32 having essentially no reactivity with difluoromethane, and having a surface ratio of silicon to aluminum of less than about 1. 7 mol/mol as determined by X-ray photoelectron spectroscopy--has been found to be an effective desiccant for refrigerants comprising difluoromethane.

R-32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The potassium cation form of a zeolite A molecular sieve--with at least 60 per cent of the sodium cations replaced with potassium ions, agglomerated with a clay binder and pore-reduced to essentially exclude the adsorption of R-32, and having essentially no reactivity with difluoromethane--has been found to be an effective desiccant for refrigerants comprising difluoromethane.
