Abstract: A cover for a tablet PC provides protection to the body while allowing free access to a touch screen and other controls. The cover has an integrally connected keyboard or other input device which can be simply deployed for use, allowing conventional keyboard- or other-based input to the PC. When not in use the input device can be stowed at the rear of the cover, complementing device protection thereto. The cover further provides support elements allowing the PC to be situated for use on a horizontal surface, with the actual angle of situation adjustable to meet individual needs. When not needed or for transport, the support elements collapse and are received within the cover. In addition, the cover allows the PC to be situated, with the input device deployed or otherwise, in either a landscape or portrait orientation.

Abstract: A low temperature flameless aerosol producing fire extinguishing composition containing potassium nitrate and binding fuel is characterized by using cellulose-fibrous mass as a binding fuel, with potassium nitrate at 30-70% and fibrous cellulose mass making up the remainder.
