Patent CA-2030214-A1 (CA)
Inventor: PLACZEK TERRANCE M
IPC: B03B1/00
Filed: 1990-11-19
Abstract: This invention relates to an improved method and apparatus to effect the separation of component fractions from paper-containing and plastic-containing waste materials.  This method and apparatus accepts materials of widely varying  characteristics  such  as  paper, plastics, glass, metal, food wastes and other materials to be inserted en masse into a rotating vessel equipped with lifting paddles and directional flighting.  In this way the intimate contact of materials with moisture and heat is accomplished, thus effecting the repulping of paper materials.  The repulped materials, as a result of directional tumbling, are dispersed throughout the vessel.  Because   of   the   repulping of  the pulpable materials, size reduction of the randomly large and odd-shaped pulpable materials is accomplished.  By virtue of the size reduction of  the   large   and odd-shaped pulpable materials, the non-pulpable components are freed of the particle  shapes and  surfaces   that   affect separation.  The repulping of the pulpable materials increases the bulk density of  those  materials, further enhancing their   separation   from  the  additional components.  The recovered pulped product is suitable for recylcing into the paper industry; for combustion as a high quality fuel; or  for   use as a feedstock for conversion into chemicals.  The recovered non-pulpable material   such as plastics, glass, metals, aluminum and other materials are  suitable for recylcing into their producer industries; as feedstock raw materials for additional manufacturing of products; or any or all of these materials can be disposed of in a sanitary landfill as is the commonly accepted practice.

Title: Crane-mounted drill and method for in-situ treatment of contaminated soil
Inventor: MILLGARD V DENNIS
IPC: E21B10/34
Filed: 1991-04-03
Abstract: Abstract of the Disclosure Apparatus for in-situ treatment of contaminated soil that includes an elongated hollow drive shaft mounted for rotation about its axis while being supported in vertical orientation. The upper end of the drive shaft is connected for selective injection of fluid under pressure into the shaft. A drill is affixed to the lower end of the shaft for drilling a hole downwardly through the soil. The drill comprises a hollow sleeve mounted to the lower end of the shaft and extending therefrom coaxially with the shaft. A pair of drill blades are cantilevered from the sleeve, and extend outwardly therefrom at right angles diametrically opposite to and aligned with each other. Each blade is of identical uniform cross section and carries a plurality of radially spaced drill teeth oriented tangentially of the sleeve along a leading radial edge of the blade. A hollow pipe extends along the trailing edge of each blade, and has orifices for injecting fluid from the sleeve and the pipe into the earth as the blade is rotated. A plate is affixed to each blade to defect soil away from the nozzle orifices as the drill is rotated. A sensor is responsive to velocity of the drive shaft and drill, and cooperates with control electronics for injecting fluid into the earth as a predetermined function of velocity of the shaft.
