  • Patent number: 10512291
    Abstract: A thermally insulating article of warmth such as an article of apparel is described and includes removable thermally insulating flexible panels disposed and removably secured between the outer shell fabric and the inner lining fabric. The thermally insulating panels are inserted through an opening having a closure and is retained in position between the outer fabric shell and inner liner by detachable fasteners. The panels are removed to change them with panels having different thermal values or properties to adapt to different climatic conditions or to wash the article without the insulation. By removing the insulation panels the article is less bulky to wash and dry and takes less time for washing and drying while preventing damage to the insulation, particularly if constructed of insulating material which absorbs humidity and has a tendency to form clumps when subjected to impact and stretching forces by the action of a washing and drying machine by being removable.

A thermally conductive layer 24 is disposed adjacent the abrasive layer 23 to conduct heat rapidly away from any localized hot spots that might develop within the abrasive layer 23 when heat from a high-temperature torch is applied to a region of the outer panel 21. A thermally insulating layer 25 is disposed between the thermally conductive layer 24 and the inner panel 22 to inhibit heat transfer from the thermally conductive layer 24 to the inner panel 22. The thermally insulating layer 25 comprises a porous ceramic material consisting of vitreously fused ceramic fibers.

  • Patent number: 5329864
    Abstract: A break-in obstructing, or burglarproof door or wall, for which old motor vehicle tires are used as filling units instead of steel structures and sheeting. The treads or strips separated from the tires form mat-like, layered, and/or stacked filling units for burglarproof doors or walls and are connected with each other and to the frame by special fastening devices. This application considerably reduces the weight of such a door, and allows for burglarproof and break-in obstructing doors and walls at a much lower production cost, due to using recycling material.

  • Patent number: 5221807
    Abstract: The armor for providing ballistic protection comprises an armor plate for stopping projectiles with an auxiliary plate disposed in front thereof at a determined spacing therefrom, the auxiliary plate being constituted by a ceramic plate pierced by a large number of cells distributed in a regular mesh and constituted by blind holes extending perpendicularly to the rear face of the auxiliary plate and opening out into the front face thereof. The effect of the auxiliary plate is to destabilize and to score the projectiles so as to enhance their tendency to shatter on striking the armor plate.

  • Patent number: 5142997
    Abstract: A space dividing system which comprises a rectangular panel having a metallic frame which includes stiles and rails arranged to form a window. The stiles and rails each have a channel which faces the window and first and second spaced internal pockets which straddle the channel. Projectile resistant material is disposed in the first and second pockets of each stile, and a rigid rectangular layer of projectile resistant material is centered in the frame window with its outer edges extending into the channels and overlapping the first and second pockets. In a preferred embodiment, layers of acoustical insulation are respectively disposed against opposite sides of the rigid layer of projectile resistant material; and, the panel is supported by an arrangement which includes both a hollow metallic post filled with projectile resistant material, and a connecting joint structure which both blocks and deflects projectiles entering the joint.

  • Patent number: 5060582
    Abstract: A bullet and blast resistance door leaf is comprised of inner and outer sheets connected by a profile section forming an end face of said leaf. The profile section includes an outer step and an inner step, the outer step extending laterally outwardly beyond the inner step. Outer and inner plates are connected to the outer and inner steps respectively, dividing the interior of the leaf into inner, outer and central chambers. A lock mechanism is mounted in the central chamber and projects through the profile, the lock mechanism being shielded by the outer plate. The inner and outer chambers may include insulation, and the outer chamber may include a sensor for activating an alarm.

  • Patent number: 4918900
    Abstract: A light-weight wall panel for a protective enclosure includes a shell of sheet metal which encases a filler structure of a combination of penetration resisting or hard wood and metal members. The filler structure includes first and second wall structures which differ from one another by the orientation of hard wood and sheets of expanded metal which are interleaved between adjacent ones of the boards. In the first wall structure adajcent one of the major surfaces of the wall panel, the hard wood boards and interleaved metal sheets have their major surfaces oriented perpendicular to the major surfaces of the wall panel. The second wall structure adjacent the other of the major surfaces of the wall panel has layers of hard wood boards and sheets of expanded sheet metal which extend with their major surfaces parallel to the major surfaces of the wall panel. The two wall structures are fastened to each other and hence into a single structure.
