International Classification:

G01N 3320

US Classification:

436 73, 436 79, 436 80, 436 81, 436 82, 436 83, 436 84, 436177, 436181, 422 83, 422 88, 422 90, 422 91, 422 92

Abstract:

A portable instrument for automatic collection and analysis of airborne lead concentrations in ambient air environments. Its improvements to the art of airborne lead detection and analysis permit the apparatus to analyze samples previously collected by personal monitors, for example, worn on the clothing of personnel working in contaminated sites. The apparatus also brings to the art of lead analysis a method of contaminant collection that ensures a greater capture efficiency of airborne contaminants, thereby increasing the accuracy of the instrument and its measurement capabilities while providing near real-time analysis and measurement in a portable self-contained battery-powered device. The apparatus also offers a remarkable improvement in the reduction of wastes incurred in the collection and analysis of airborne lead contaminants which is a novel method of concentrating the samples and recycling the analysis media used to concentrate and solubilize lead contaminants.

International Classification:

G01M 326

US Classification:

137557

Abstract:

A leak detection system for detecting a fuel leak from a storage tank comsing a vertically positioned reference tube that spans the full useful length of the fuel tank which is generally located underground. The reference tube is filled and drained with the tank. The system also has a normally open pneumatic by-pass valve which when closed isolates the reference tube from the tank. A differential pressure gauge between the tank and reference tube reads zero pressure immediately after closure of the by-pass valve. A differential pressure reading between the tank and reference tube indicates the presence of fuel leakage from the tank. The inside of the reference tube is tapered at the top portion and bottom portion of the tube to match the cross sectional area of the tank upper dome and lower tank dome ends, while the outside diameter of the tube remains constant through out the length of the tube. A plurality of six inch pipe inserts having different inside diameters are slid into the reference tube at the top portion thereof tapering the top portion of the reference tube. Similarly, a plurality of six inch pipe inserts also having different inside diameters are slide into the reference tube at the bottom portion thereof tapering the top portion of the reference tube.

Abstract:

There is provided a process for biodegradation of TNT (2,4,6-Trinitrotoluene) wherein the biodegradation is done utilizing the fungus Phanerochaete chrysosporium strain BKM F-1767, wherein waste containing TNT is treated with the fungus under predetermined conditioning and for a time period sufficient for biodegradation to occur rendering the waste ecologically acceptable to the environment.
