Patent number: 7001758Abstract: A biodegradation process for the organophosphonate product of Sarin (O-isopropyl methylphosphonofluoridate) hydrolysis, i.e., isopropylmethylphosphonate (IMPA). This process provides a feasible biodegradation demilitarization alternative to Sarin incineration. Public opposition of nerve agent incineration is widespread, and alternative methods are sought to help the U.S. Army meet the 2007 demilitarization deadline imposed by the Chemical Weapons Convention. This process uses a two-step approach to IMPA biodegradation. In the first step, a concentrated IMPA solution is used as the sole nutritional carbon and phosphorus source for microbial cultures. The second step involves diluting the culture and adding an inexpensive carbon source to encourage bacterial phosphate assimilation. The biodegradation typically involves a consortium of microorganisms comprising Methylobacterium radiotolerans GB21, Agrobacterium tumefaciens GB2GA, Klebsiella oxytoca GB2CS, GB272, Aureobacterium sp.Type: GrantFiled: May 12, 2003Date of Patent: February 21, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Ilona J.

Patent number: 6985818Abstract: A continuous monitoring method and system wherein a porous substrate or film is used. The air from the environment is drawn through a region of the porous substrate by a simple air pump and the substances in the air are deposited or chemically adsorbed onto the surface of the substrate. The region of the substrate where the environmental air is drawn through is continuously monitored by an optical or spectrometric method. The substrate is in the form of a tape supplied by a feed reel in a reel-to-reel cartridge and taken up by a take-up reel as found in a film cartridge or a magnetic tape cartridge. The cartridge can be replaceable. A variety of materials may be employed as the substrate with an adequate surface area to effect accumulation of solid, liquid, aerosol, or gas phase compounds.Type: GrantFiled: February 6, 2003Date of Patent: January 10, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Alan C.

Patent number: 6929226Abstract: A twist lock mount for quick mounting and positioning a device to a support includes a mount receiving member attachable to or integral with the support and a mounting member attachable to or integral with a device to be mounted. The receiving member provides a channel covered by flanges that further define a narrower channel or slot. The mounting member is configured to slide into the channel when it is in one rotational orientation and to lock securely into place when it is in another. A rotation in the opposite direction will unlock the device so that the mount can be slid out of the channel quickly and easily. The twist lock mount simply and effectively prevents movement in the longitudinal, transverse and axial directions and is well suited for use in harsh, high vibration environments.Type: GrantFiled: August 11, 2003Date of Patent: August 16, 2005Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John J.
