Abstract: A hardened telescoping load carrying device includes a plurality of telescoping container sections with interlocking edges and a door with interlocking edges. The telescoping sections are loaded with baggage one at a time and then extended outwardly. The interlocking edges on the telescoping sections interlock when the device is in the fully extended configuration. The interlocking edges on the telescoping sections and on the door engage with increasing force in the event of an explosion within the device.

Abstract: A fire-resistant safe is made with internal and external shells that are filled with insulation material. Hollow reinforcements interconnecting the two shells are formed as cone-shaped recesses in the internal shell having truncated bottom portions attached to the external shell. The insulation is made of a water-bearing material and the recesses are made of a resin material that melts at a temperature in excess of the boiling point of water. Funnels are formed in the external shell for adding the insulation material in a liquid state. An escutcheon for covering the funnels is anchored to the insulation material by stakes that are embedded in the insulation material before the material hardens into place.

Abstract: A hardened load carrying device includes a unitarily constructed container for holding the load. The container has an opening which is partially bordered by a slot that includes opposed crooked thumbs which project into the channel of the slot. A door for covering the opening of the container has a pair of opposed crooked fingers which are attached along part of the edge of the door to establish a bite. To enclose the load in the container the bite of the door is slidingly received into the slot bordering the opening to cover the opening and engage the crooked fingers of the door with the crooked thumbs of the slot. In an alternate embodiment the crooked thumbs of the slot are replaced by opposed lips which extend inwardly to establish a T-shaped slot, and the crooked fingers and the door are replaced by a flange which is slidingly received into the T-shaped slot. Any joints which are established between panels of the container are reinforced using a double thickness of material.

Abstract: A file cabinet is disclosed which has a door with high sound absorption properties. The door has metal front and rear panels and an intermediate layer of sound absorbing material sandwiched therebetween. An array of openings are cut through both the front and rear panel. Sound impinging on the front panel enters the cabinet via the door and is attenuated in the door and cabinet. Preferably, paper files are stored within the file cabinet with their peripheral edge surfaces disposed towards the rear panel to assist in attenuating sound within the cabinet.

Abstract: An improved fire-extinguisher cabinet for insertion into a vertical wall surface consisting of double fire wall cabinets creating an internal cavity which hold a fire-retardant material. The improved double-walled fire extinguisher cabinet satisfies all the requirements of the Uniform Building Code 43-6 "Fire Tests of Through-Penetration Fire Stops" based on ASTM 81-4-83 of the Warnock Hersey International (WHI) of Middleton, Wis., test label for 1- and 2-hour combustible and noncombustible walls. When installed and exposed to a fire the improved double-walled extinguisher cabinet will not permit and/or will retard the spreading of the fire at the installation sight. In addition, the improved double-walled fire extinguisher cabinet provides a convenient, easily accessible, cabinet for containment of a fire-fighting apparatus.

Abstract: A fire-resistant safe has a main body and a closure, both of which are formed from integral resin shells filled with insulation materials. When exposed to fire, a portion of the resin material burns away leaving gaps between the insulation materials of the main body and closure. However, formation of convection air currents in vertical sections of the gaps is resisted by reducing spacings between insulation materials of the main body and closure. The amount of heat energy carried by the convection air currents is similarly reduced, thereby avoiding significant concentrations of heat that can promote burning through the gaps.

Abstract: An upright freezer including a housing having a plurality of openings on one side thereof and a plurality of drawers, each of which is passable through a respective one of the openings. The drawers are supported in the housing by cooperating rollers and rails mounted on respective ones of the drawers and interior side walls of the housing. Each of the openings is closed by an individual door which is pivotally attached to the housing. The doors include a latch or a magnetic seal extending therearound to seal the respective opening in the housing. Alternatively, a latch and a magnetic seal can be provided on each of the doors. The housing also includes apparatus for maintaining the interior of the housing at a temperature below freezing. Each of the doors can include a tab holder thereon for holding a label which indicates the contents of the drawer slidably received within the opening sealed by the respective door.
