Abstract: A method of positioning an arcuate catheter against an inner annular wall of the disc, and particularly on the posterior and postero-lateral portions of the inner annulus of the disc, by arthroscopy is presented. The arcuate catheter retains its predetermined arcuate shape when no pressure or force is applied to the catheter. This present device and method require no forward tip pressure on the inner annular wall of a mammalian intervertebral disc. An arcuate sheath having a cutter is used to remove tissue from the inner annulus of the disc. In another embodiment an arcuate sheath is used to progressively remove material from the interior of the mammalian intervertebral disc. In yet another embodiment, an arcuate sheath and catheter are used to remove the entire intervertebral disc and place supports to maintain a disc space.

Abstract: This invention provides a method for stabilization of hexavalent chromium and trivalent chromium bearing wastes, materials, and contaminated soils subject to acid and water leaching tests or leach conditions by addition of water solution, hexavalent chromium reducing agent, precipitating and pH increase agent, and chromium reversion control and stabilizing agents such that leaching of chromium is inhibited to desired levels and resists reversion to hexavalent chromium form over time. The resultant material, contaminated soil and/or waste after stabilization and reversion control is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.

Abstract: The invention pertains to a method for reducing the leaching of heavy metals from air particulate emissions. The method includes contacting the heavy metal particulate with a water and complexing agent which converts the molecular form of the particulate to a less soluble and less bioavailable form prior to collection and release to the environment. This method eliminates the need to remove or treat soils and environments exposed to particulate deposition and greatly reduces the environmental and health risks associated with the deposition of heavy metal particulate in the open environment as well as at controlled discharge areas.

Abstract: This invention provides a method for stabilization and treatment of heavy metal bearing materials and wastes subject to acid leaching tests or leach conditions and odor limits by addition of acid semi-soluble DiCalcium Phosphate DiHydrate such that the leaching potential is inhibited to desired levels and odors are reduced to desired levels and the material or waste is free flowing, more permeable, less weight and permits immediate handling and disposal or reuse. The resultant material or waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.

Abstract: A cleaning swab has an elongated handle defining a longitudinal axis and having a diameter. The handle has a cleaning head end. A cleaning head is formed from a sheet of non-linting material having a predetermined thickness so as to form a predetermined cleaning head diameter. The material forms a seal-less tip and a pair of longitudinal side seals extending along longitudinal sides of the cleaning head. Excess material forms a cleaning surface suitable for standard polish and angle physical connector polished end faces. A sleeve has a central opening for receiving the handle such that the cleaning head extends beyond an open end of the sleeve. Use of a first predetermined thickness of material forms a first swab having a cleaning head having a first diameter cleaning head and use of a second different predetermined thickness of material forms a second swab having a second different diameter. The sleeve is configured to interchangeably receive the first swab and the second swab.

Abstract: A fiber optic component cleaning tool includes a container defining a body having an outer wall, a sealed bottom wall and an open end, the open end defines a periphery. A compliant, large work surface is disposed on at least a portion of the outer wall. A plurality of cleaning wipes are disposed inside the container. The wipes are pre-moistened with a solvent. A seal extends over the container opening and is sealed to the container at the periphery. The seal has a frangible portion therein to define an opening. A lid is fitted to the container over the open end. The lid has an opening for cooperating with the frangible portion of the seal. Cleaning wipes are fed from the inside of the container through the opening in the seal and the opening in the lid, and are placed on the work surface for cleaning the fiber optic component. The wipes are formed from a non-woven material such as a blend of a natural and a synthetic material.

Abstract: A cleaning device is configured for cleaning a male portion of an aligning-type fiber optic connector. The device includes a container having an opening in a face formed in a side of the container. A plurality of discrete soft, large work surfaces are disposed on a face formed in a side of the container. The surfaces are disposed in side-by-side relation to one another having open regions between the surfaces. The open regions are at an elevation lower than an elevation of the plurality of work surfaces. A plurality of cleaning wipes are located inside the container. The wipes are fed from the inside of the container through the opening and placed on the work surface for cleaning the connector.

Abstract: A method of removing matrix from a fiber optic cable includes the steps of providing a foil layer, placing a sheet of wiping material atop the foil layer, positioning a portion of fiber optic cable coated with a matrix on the sheet of wiping material, folding the foil layer and sheet of wiping material together, spraying solvent into the folded wiping material, and confining the fiber optic cable inside the folded sheet of wiping material within the folded foil layer until the matrix dissolves. A durable folder may be used with the method to provide a portable work station and secure both the sheets of wiping material and the foil layer. A portable containing materials necessary for practicing the method of the present invention also is disclosed.
