Patent number: 4800823Abstract: An improved storage device is provided for enhanced protection from fire and theft. It has advantages of lightweight for transportation and installation, heavyweight for protection when in use, steel construction for theft protection, dry insulation for heat flow retardation, fluid for limiting internal temperature rise and low cost. These capabilities are achieved by constructing a multi-walled storage device having an inner wall of steel for theft protection, an outer chamber of insulation to reduce heat flow from an external source, and an internal chamber for filling with a fluid to absorb heat and thereby reduce the maximum temperature. The fluid boils off at a particular temperature and pressure to limit internal temperature. The outer insulation limits heat flow, thereby reducing the rate that fluid boils off. Duration of temperature limit protection is a function of heat capacity and heat of vaporization of the fluid and heat flow through the insulation.Type: GrantFiled: January 12, 1982Date of Patent: January 31, 1989Inventor: Gilbert P. Hyatt

Patent number: 4574454Abstract: The body of a cabinet for storing temperature-sensitive articles such as magnetic discs and tapes is built by a process which involves the successive steps of (i) fabricating an internal skin; (ii) attaching so-called "phase-change" material to the skin; (iii) applying insulative polyurethane foam in-situ to the structure of step (ii); (iv) casting concrete or the like water-bearing material around the structure of step (iii); and (v) completing the outer finishing skin. Thus the conventional "double-box" structure is avoided. The door for the cabinet can be built by a similar sequence in which "phase-change" material, insulative form and water-bearing layers are applied successively to a pan forming the internal face of the door.Type: GrantFiled: January 14, 1985Date of Patent: March 11, 1986Assignee: Chubb & Son's Lock and Safe Company LimitedInventor: George W.
