Abstract: An underground air cooling system and method for at least one building including an air line disposed beneath the ground for conveying air to an I-tank filled with fluid that is also disposed beneath the ground. The fluid in the lower compartment of the I-tank absorbs heat from the air in the air line and dissipates that heat quickly to the surrounding earth and to the fluid in the upper compartment of the I-tank. In addition, a fluid line is connected to the I-tank and is interposed in the path of the air in the air line. Cold water from the I-tank runs through the water line. As air passes over the fluid line in the air line, the air is further cooled and dehumidified before being conveyed to a building to be cooled. In a preferred embodiment, a second water line is connected to the lower compartment of the I-tank and is disposed in different parts of a building so that cool water from the I-tank runs through coils of the second water line in different portions of the building.

Abstract: This invention relates to the art of certain new and useful improvements in means and methods for shrub and tree surgery, and more particularly to a use of fiberglass and fiberglass resin and hardener techniques to more effectively treat tree wounds and cavities. Such methods and means have been found more successful than other tree surgery methods now in use, i.e., the use of concrete filler, sheet metal plates, etc. for permanent tree healing and for insect and element protection.Two procedures are used, dictated by the type of injury, (1) a combination of fiberglass resin and hardener can be applied directly to damaged exposed wood tissue (where branches up to 12 inches in diameter have just been removed, or other exposed tissue areas such as trunks, roots, pruned limb ends, etc.
