Abstract: A system and apparatus has been developed for factory built panelized, precast insulated concrete walls. The interior as well as the perimeter walls of the home are solid reinforced concrete. The concrete walls make a home fireproof, low maintenance, air tight, with thermal mass for heat storage insulated on the outside which makes it more energy efficient. Concrete for the exterior walls is poured over a rigid insulation board so that when the walls are erected they are insulated on the outside. This protects the concrete from the elements and makes the concrete available to the interior of the building for thermal mass to store heat. The walls are poured in one continuous row and cut into individual panels after hardening. Lifting bolts, anchor bolts, weld plates, electrical outlets, window and door placement are all indicated on the top plate at the manufacturing plant. The manufactured reinforcing panels are laid on casting slabs for concrete to be poured and finished.

Abstract: A well cleaning apparatus and method of treating a well includes a generally tubular implement which has a first section with adjustable, radially extending cables, and a second section with cable loops extending outward, a bottom cone-shaped plug and a top plug. The first section cables can be anchored by rotating or sliding a crimping tube therein, or by molten material poured therein. The second section cable length can be adjusted by a sliding base bracket. The first section chops up scale, sludge and tar while the second section cables sweep them away. The method includes these steps, as well as steaming the casing at high pressure and low water volume to aid cleaning, and stimulate formation flow without creating sand bailing problems. The apparatus can be attached to the bottom of a well pump, with several first sections spaced along the length of the work string of the pump to enable cleaning of the entire well casing by a limited upward and downward movement of the entire assembly.
