A blend of cellulosic material and thermoplastic fibrous material, wherein the latter comprises between 3%-15% of the blend by weight, is formed by a method such as air-laying into a low density, high loft mat. The surface of the mat is flame-treated to melt the thermoplastic component on the surface, forming a skin which keeps the cellulosic component intact. The thermoplastic component in the interior of the mat remains unmelted, thereby providing the mat with a spring-back characteristic which allows the mat to retain most of its original shape and loft even after it has been compressed for shipping. A facing sheet can be applied to the surface of the mat, as is done with conventional fiberglass batt-style insulation.

  • Patent number: 4952268
    Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film as the intermediate layer for the waterproofing material and the film has a plurality of perforations therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers, thus providing superior protection from the elements. The asphalt layers are interconnected with each other through the perforations in the polyester support layer. Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns so formed to attach the asphalt to the film.

  • Patent number: 4582554
    Abstract: A method of backing carpeting material 19 with hot-melt compositions such as atactic polypropylene or bitumen comprises carefully doctoring selected thicknesses of the composition to the undersurface of the material 19 with the wear surface of the material uppermost. In one arrangement this is achieved using a lick roll arrangement 20 incorporating a doctor blade, cooling the backed product at cooling zones 28, 29 and applying the material to a nip formed by rollers 21. In another arrangement this is achieved by doctor box 16 applying the composition to a carrier 13, the carpeting material 19 then being laminated at roll 21 to the layer of composition, the laminate then being cooled before being stripped from the carrier 13. In a further arrangement the carrier is in the form of sheet material 15 which is supported by endless belt 13 and which is bonded into the hot-melt composition to become an integral part thereof.

  • Patent number: 4576661
    Abstract: The structure and process for providing a sealed insulated piping arrangement by introducing a molten sealing material between the inner fluid conducting pipe, and an outer casing, which space may include monitoring wires. The sealing material is introduced in a molten state to provide a liquid-impermeable filling, and then providing an enclosing seal at the end with a smooth transition for passage of the monitoring wires.

  • Patent number: 4574019
    Abstract: Carbon anode blocks for use in the fused salt electrolytic process for producing aluminum, are attached to the studs or spades of an anode suspension means by an adhesive mass which is mechanically strong and a good electrical conductor at least at temperatures between 900.degree. and 1000.degree. C. The studs or spades are preheated to 30.degree.-60.degree. C. and/or the anode blocks at least in the region of the holes for the said studs or spades to 25.degree.-40.degree. C. At the latest 60 seconds after inserting the anode suspension means i.e. after immersion of the studs or spades in the cold-poured adhesive mass, the adhesive mass exceeds a temperature of 25.degree. C. The lowering of the studs or the spades is achieved in the shortest possible time by vibrating the anode blocks and/or the anode suspension means. The stabilizing of this arrangement, at least until the adhesive mix has partly hardened, is achieved preferably by spiking or wedging.

  • Patent number: 4565724
    Abstract: The invention relates to a roofing-material provided with perforations and comprising a bituminized carrier with a non-sticking lower surface and destined for being applied on a substratum and for being covered by an upper layer, which may contain a carrier which is bituminized with modified bitumen, and which may be applied by means of a torch.According to the invention the carrier of the roofing-material is bituminized with modified bitumen, and the perforations are so large that the upper layer can be directly applied on the roofing-material by means of a torch and can be adhered to the substratum via the perforations.

  • Patent number: 4555283
    Abstract: A storage tank for liquid bitumen including a steel shell having heat insulation adjacent to its interior surface. The insulation is glass foam. Preferably, the insulation is in the form of glass foam panels which are initially arranged with gaps between them. When the tank is filled for the first time, the liquid bitumen penetrates into the gaps and solidifies therein to permanently interconnect the glass foam panels. A glass foam insulating cover floats on the surface of the liquid bitumen, and a heating unit is located within the tank.

  • Patent number: 4417939
    Abstract: A system for producing a relatively thin bitumen laminate comprised of an bitumen mastic core to which is adhered a fabric web on each side thereof, adherence being established simply by contacting the fabric web with the bitumen mastic while it is hot. The method includes continuous deposit at a fixed location of hot bitumen mastic to form the core on a moving lower fabric web, the laminated lower fabric web being in direct contact with a fluid cooled endless belt to prevent degradation of the fabric. The bitumen mastic is deposited on the lower web as it traverses the endless belt's upstream end roll, thereby insuring a firm, non-flexible surface upon which the mastic core can be sized by a doctor roll on the lower web. A moving top fabric web is laminated to the sized bitumen mastic core on the lower web at a location that is variable relative to the fixed location at which the mastic is deposited on the lower web.

  • Patent number: 4395299
    Abstract: Bulk pieces of graphite bonded with a graphitizable binder comprising a lid crystalline component of pitch, which softens at about 240.degree. C. and becomes very fluid at about 300.degree. C. to about 500.degree. C. The bonded graphite pieces appear as a monolithic material even under 1000.times. magnification. The bonding is effected under vacuum or in an inert atmosphere at temperatures of from about 700.degree. C. to about 3000.degree. C., usually about 1000.degree. C. to about 1500.degree. C., under pressure of from about 20 psi to about 1000 psi applied in a direction normal to the bonding surface.

  • Patent number: 4386981
    Abstract: Roofs of buildings and the like are waterproofed by applying thereto a plurality of preformed, sheet-like, flexible waterproofing laminates each comprised of (i) a lower sheet support layer (preferably a plastic film or foil) non-removably adhered to (ii) an intermediate layer of waterproofing, self-adhesive, bituminous composition such as rubberized asphalt which in turn is removably adhered to (iii) an upper layer of protective sheet material (e.g. siliconized paper). The surface of the lower sheet support (i) remote from the bituminous layer (ii) is non-adherent and the laminate is applied to the roof with such non-adherent surface adjacent the roof. The uppermost protective sheet layer (iii) is subsequently removed exposing the self-adhesive bituminous layer to which is thereafter applied a weathering layer (e.g. a coating of gravel). The non-adherent surface nature of the lower sheet support layer allows any moisture entrapped below the applied waterproofing laminate to move and be distributed or vented.
