  • Patent number: 4353949
    Abstract: A method for producing a decorative design on a substrate by applying to the substrate an embossable coating comprising a filler, a binder, a release agent, a moisture control agent, and a liquid; drying the applied coating to remove a major portion of the liquid therefrom, sufficient liquid being retained to make the coating pliable and readily impressible by an embossing means; and subjecting the pliable coating to pressure contact with the embossing means, which is at ambient or an elevated temperature, to impress a decorative design into the coating; and the embossed coated substrate produced by the method.

  • Patent number: 4346133
    Abstract: A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam may be any polymeric material which is capable of being foamed. Distributed substantially evenly throughout the foam is a mat of long glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long glass fibers with a foam-forming mixture, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture therebetween through means for metering the amount of foam-forming mixture and causing it to fully penetrate between the fibers of said glass mat.

  • Patent number: 4335083
    Abstract: A method for leaching magnesium from a magnesium hydroxide-containing composition, especially a mineral, which comprises contacting said composition with an aqueous solution of an ammonium salt whose corresponding magnesium salt is soluble in said aqueous solution to thereby produce said soluble magnesium salt; separating said aqueous solution from said composition; and transforming the magnesium of said soluble magnesium salt into an insoluble magnesium compound. The method is particularly useful for leaching magnesium from brucite-containing chrysotile asbestos fibers, to yield both a magnesium compound and brucite-free, dispersed chrysotile fibers.

  • Patent number: 4319921
    Abstract: Metallic scrap contaminated with combustibles is melted in a reverberatory melting furnace having two communicating wells; one being an enclosed sidewell, which is the receiving well for scrap material during melting, and the other being an enclosed main holding well for molten metal. The main well has burner means to provide heat for melting the metal and treating the scrap material. Heat from molten metal flowing between the main well and the sidewell produces exhaust gases by vaporizing the combustibles of the scrap material. An external passage circulates the exhaust gases from the sidewell to the main well for incineration by the main well's burner means. The external passage has an eductor means which draws the exhaust gases from the sidewell and propels them towards the main well.

  • Patent number: 4316935
    Abstract: A foam characterized by the presence of isocyanurate groups which is the reaction product of a polymethylene polyphenyl isocyanate, such as that of the formula: ##STR1## wherein n is an integer from 1 to 8 inclusive, and a furan resin of the formula: ##STR2## wherein R is --CH.sub.2 -- or --CH.sub.2 --O--CH.sub.2 --, and the average value of m is such that the furan resin has a viscosity of up to 50,000 centipoises at 25.degree. C. The foam exhibits a low friability and an improved capacity to maintain its structural integrity when exposed to fire, and can be used in structural laminates.

  • Patent number: 4280732
    Abstract: A method of mining a mineral deposit from a remote point, particularly useful in mining pitching or horizontal seams, comprises boring, casing and preparing a log of a probe hole; the casing will later be used as a guide for the mining head. All personnel are remotely located from the mining face and the mining head follows the probe hole and is rotated by means of a novel drive stem powered from a portal based plant. Thrust is imparted to the rotating mining head in a non-cyclical manner by the intermittently supported drive stem. The mineral being mined is automatically removed from the face and discharged at the portal. Steel or reinforced concrete support collars follow the mining head and support the drive stem until the bore is mined out whereupon the collars, the drive stem and the guide are removed for reuse.

  • Patent number: 4266388
    Abstract: A template for positioning an array of overlapping shingles on a roof comprises a body member having a side edge contoured to fit the side edge pattern of the array of shingles to be established on the roof, whereby the shingle positioning is accomplished by setting on the roof a first shingle of the array, positioning the template on the roof so that a portion of its contoured side edge abuts the corresponding side edge portion of the first shingle of the array and thereafter guiding the placement on the roof of each of the remaining shingles of the array by abutting a side edge portion of each against the corresponding side edge portion of the template's contoured side edge.
