Abstract: A protection film for a touch sensitive screen includes an adhesive substrate cut according to a shape of the touch sensitive screen. The adhesive substrate is disposed over a temporary liner. The adhesive substrate is transparent. A transparent polymer material is dispensed over the adhesive substrate. The transparent polymer material includes a flat surface formed by nature of the transparent polymer material flowing due to gravity and a convex edge formed by nature of a surface tension of the transparent polymer material. A coating is formed over the transparent polymer material. The transparent polymer material is cured. The temporary liner is removed after curing the transparent polymer material, and the protection film is attached to the touch sensitive screen. The protection film includes a thickness ranging from 0.2 millimeters (mm) to 1.5 mm. The touch sensitive screen remains functional with the protective film attached to the touch sensitive screen.

Abstract: A kit is provided for use by an end user to apply a protective cover sheet material to an electronic device. The protective sheet includes visual enhancements for giving a unique look to the electronic device without altering the design and shape or form of the electronic device.

Abstract: The method of treating used liquid coolant employed in the coolant passages of an engine or radiator, and employing a coolant pumping structure, that includes providing a source of supply coolant liquid, and a used coolant reservoir; operating the pumping structure to displace supply coolant liquid from the source into the coolant passages, thereby displacing used coolant from the passages for flow into the reservoir structure; and chemically treating the used coolant liquid to remove metallic and other contaminants therefrom, thereby to produce treated coolant liquid usable as the supply coolant liquid.

Abstract: The method of removing hot liquid coolant from an internal combustion engine cooling system, which includes a radiator having a by-pass outlet, the method including applying suction to the by-pass outlet to draw a by-pass stream of hot fluid, including hot pressurized gas, from the radiator, thereby to reduce fluid pressure in the radiator; and then opening the radiator for safely removing hot liquid coolant therefrom; The removed liquid may be disposed of or treated in a zone or zones outside the cooling system; and returning the treated coolant liquid may then be returned to the cooling system.
