  • Patent number: 6862852
    Abstract: The invention releases to a sealing system comprising a cylindrical tube of a material that is capable of deformation under the influence of a temperature increase, and a gasket of an at least partially elastic material for sealingly retaining the tube in a lead-through housing coaxial with the tube by forming a collar therearound, wherein said gasket is made of a fire-retardant material with a base of a cross-linkable material and an expandable material, in such an amount and of such a composition that a temperature increase above the plasticizing point of the tube will cause the gasket to expand to such an extent that the tube is compressed and a medium-tight seal of the lead-through housing and the tube is obtained.

  • Patent number: 6841209
    Abstract: The present invention contemplates water-bearing silicate materials achieved by modifying the basic method of essentially reacting water glass with calcium chloride to bind the free water into solid form without adversely affecting the basic chemical and physical structure of the original product. The material is then dried by using a physical wicking agent, such as a cellulose sponge, adding an anhydrous salt to the material to form a crystalline hydrate, or adding calcium oxide or calcium hydroxide to the material to form a microstructure that physically retains the water. The material is then incorporated into a fire protection container in which the material forms the outermost wall of the container, a light-weight porous material such as urethane foam an intermediate layer, and a phase change material with a melting point of around 70 degrees F. to 125 degrees F. forms the innermost wall.

  • Patent number: 6732481
    Abstract: An intumescent firestopping apparatus used in poke-through applications for selectively sealing an opening through a construction barrier such as a wall, floor or ceiling having cables or other penetrating members extending therethrough. The apparatus effectively seals this barrier responsive to a fire to prevent unwanted transmission of fire through conventional construction barrier areas. The apparatus includes a sleeve with two intumescent pads positioned therein. At least one of the pads has an arcuate curved central section to be biased against the other intumescent pad to define therebetween a confinement area for holding of cables centrally located therein in a dynamically adjustable sealing throat defined therebetween. These pads can be variously mounted with respect to the adjacent wall structures and one or both of the pads can be arched toward the other pad to facilitate defining of the dynamic throat for receiving cables extending therethrough.

  • Publication number: 20040074200
    Abstract: A metal framing member for use as a stud, joist, rafter, truss, etc. is disclosed. The framing member includes at least one knock out opening and a corresponding tab that is positioned onto the metal framing member during the manufacturing process via computer so that structures built using the studs such as window frames, door jams, etc. are accurately and quickly fabricated. The knock out opening can also be used as a chase to allow wiring or a stiffening rod to pass through the member. Each tab is also preferably provided with a pair of pre-punched holes so that the tab can be fastened to other building components using standard screws.

  • Patent number: 6705056
    Abstract: A method and apparatus for installing backing in walls which include a first, second and third upright U-shaped stud. A first backing member has a first end, a second end, a top, a bottom, a first side and a second side. The first backing member is disposed between the first and second studs. A second backing member has a first end, a second end, a top, a bottom, a first side and a second side. The second backing member is disposed between said second and third studs. A hinge is operatively attached to the first side of the first and second backing members for permitting the second backing member to pivot with respect the first backing member between a first position wherein the first side of each of the first and second backing members are substantially in the same plane and a second position whereby the first and second backing members are not in the same plane. This permits the first backing member to be placed between a first and second adjacent vertical stud.

  • Patent number: 6658801
    Abstract: A portable fire curtain system to provide a cloak to cover a vented opening. When deployed it will alleviate the incoming wind, which is fueling the fire. The fire curtain is made of one sheet of a fire resistant or fire proof material that is folded and sewn together. Encapsulated within the fire curtain are 6 bars of high-tempered aluminum running laterally. Each corner of the fire curtain has holes that are drilled through the top and bottom bars. Four 5 foot cable leaders with loops, (one to each corner) will be secured to these holes. Two 40 foot ropes with snaps on all ends will be connected to these cable leaders to be used in the deployment. The ropes are packed in two rope deployment bags in order to prevent the ropes from tangling.
