Abstract:
A method for applying liquid, foam and/or gel forms of asbestos digestion chemicals through painted, coated or otherwise protected or encapsulated surfaces of asbestos-containing materials. The method includes forming an injection aperture in the encapsulating material and contacting the hazardous asbestos-containing material with asbestos digestion material through the injection aperture. As a result of the treatment, the asbestos digestion material converts the hazardous asbestos-containing material into non-hazardous material.
Method And Apparatus For Reducing Noise Using A Plurality Of Recording Copies
The present invention provides a method for reducing noise using a plurality of recording copies. The present invention produces a master file with lower noise than the available recording copies, and avoids the problems of losing musical content caused by prior art pop and click removers. The system comprises a recording playback unit, a computer system with a sound input capability, and a high capacity storage system such as a CD recorder. In operation, a plurality of recording copies of a single recording are played on the playback unit. These recordings are digitized by the computer and a separate recording file is formed for each copy of the recording. The recording files are then synchronized. The samples from each of the recording files are then averaged to reduce the noise components. A variety of threshold comparison techniques can be employed to eliminate samples and/or recording files that are outside of a computed range for that sample based on the values of the master, the other slave files or a combination thereof.

Abstract:
A composition for converting asbestos-containing material to environmentally benign components is provided. The composition comprises a flouro acid decomposing agent which can be applied to either amosite-containing thermal insulation or chrysotile-containing fire-proof material or to any asbestos-containing material which includes of chrysotile and amosite asbestos. The fluoro acid decomposing agent includes FP(O)(OH). sub. 2, hexafluorophosphoric acid, a mixture of hydrofluoric and phosphoric acid and a mixture of hexafluorophosphoric acid and phosphoric acid. A method for converting asbestos-containing material to environmentally benign components is also provided.
