Abstract: Mobile metal foundation installation apparatus and method are disclosed including a push-it carriage movably supported through controllable positioning to push a metal foundation into the ground by hydraulic cylinders pushing against a header frame held and secured in adjustable positions on a mobile tower. After the hydraulic cylinders extend to a maximum extension, the pushing reaction bar can be advanced to a lower position in the side frame of the tower. As the foundation is pushed into the ground, at least one vibrator on said push-it carriage is actuated for vibrating the cylindrical foundation body and longitudinal fins. An auger is aligned below the push-it carriage to drill in advance of pushing the metal foundation into the ground in one step. Outboard satellite anchors hold down the mobile tower when the foundation is pushed into the ground. A second auger mounted and detachable on a crane drills holes for the outboard satellite anchors.

Abstract: An industrial waste management facility (IWMF) for disposing of spent potlining includes a co-current gas-fired rotary kiln for containing a molten pool of spent potlining throughout the entire length of the rotary kiln from the inlet to the outlet, an ash quencher and cooler for receiving molten residue from the discharge end of the rotary kiln, a secondary combustion chamber, and a down-draft transition chamber for channeling discharge gases from the rotary kiln to the secondary combustion chamber. Pneumatic injection slingers feed and distribute spent potlining into the inlet end of the rotary kiln. A discharge dam provides a predetermined average depth of molten bath material in the rotary kiln over its entire length. A blended ratio of comminuted materials injected through the pneumatic injection slinger feeder is adjusted and controlled in response to signals received from a radiative optical kiln bath temperature measurement system.

Abstract: Particle filtration of a feed of highly corrosive ultra pure water and contaminants is disclosed through a metal oxide membrane on ceramic support in combination with on-line ozonation. In one aspect, the filtering of ultra pure water includes passing the feed cross-flow through a multichannel sintered monolithic metal oxide membrane on ceramic support to form a permeate of particle-free ultra pure water. Although high recoveries per pass rates were used, no detectable metal ions including aluminum, zirconium, or yttrium ions were found in the ultra pure water permeate. The apparatus and process of the present invention for filtering ultra pure water include cross-flow filtration using multichannel monolithic ceramic membranes at suitable pore sizes in a total chemical process system including elevated temperatures and on-line ozonation sterilization of the ceramic membrane particle filter in high purity water applications for electronics manufacturing.

Abstract: Flexible, elongated, tubular ducts or conduits are assembled above ground on transverse supports into a duct bank of an array of layers held by a plastic grid of transverse spacers. An underground trench can be excavated having substantially straight sidewalls, while excavated soil from the trench is placed on the side away from the assembled duct bank. Two or more pieces of equipment, spaced apart, sequentially lift and laterally move the assembled duct bank to the trench. Transverse support members spanning the trench are removed, and the assembled duct bank is lifted and lowered sequentially into the trench using a small angle of displacement from the horizontal while lowering the assembled duct bank onto transverse support members positioned in the bottom of the trench, to provide an underground duct bank. Round, freely rotatable, plastic spacers in groups of four facilitate lowering the assembled duct bank into the trench.
