Abstract: A construction material light weight as compared to standard concrete yet having excellent thermal insulation qualities. The material when processed uses cement, pumice in small size particularized form and/or volcanic ash, scoria in particularized form, vermiculite in flaked particle form and water for the cement. While excellent product may be formed with these ingredients alone a more uniformly predicable product may be produced if, prior to mixing of all the ingredients, the vermiculite is mixed with kerosene on the ratio of approximately one cubic foot to one fourth cubic foot. The vermiculite is then mixed with the pumice to kerosene coat the pumice to block absorbtion of water from the water cement mixture by the pumice to thereby insure proper curing of the cement binder in the overall material mix.

Abstract: A polyurethane RIM method has two mixheads. Reactants are brought to each mixhead and are supplied as separate streams to two spaced cavities in a mold having a pre-formed porous mat separating the two cavities. One stream contains an isocyanate, polyol, chain extender and crosslinker selected to have a very low viscosity and which reacts to produce a high modulus armature or load bearing member. The other stream contains a polyol and isocyanate with additives that have relatively high viscosity to produce a semi-rigid polyurethane foam. At each mixhead the proportions of ingredients are controlled to give a desired isocyanate index to control the flex modulus and other properties of the loading bearing member and foam molded components of the product. The low viscosity material penetrates the porous mat to reinforce it and the porosity of the mat prevents the high viscosity material from entering the armature cavity so as to reduce the load capacity of the finished product.

The lower tile is composed of lightweight ceramic normally acceptable in this application. One or more lightweight rigid or flexible insulation materials are used in the cavity created by combining the upper shell and lower tile. The assembly of the overall tile is facilitated by attachment means effective to withstand the temperature and stress conditions.

Abstract: Tarpaulins (sometimes termed "tarps") are used to protect an underlying structure or material from wind, rain and the other effects of the weather. Some tarpaulins are insulating in nature. Such insulating tarpaulins in the past have comprised weatherproof membranes with a plastic foam or polyester fiberfill portion between the membranes. These prior membranes have been characterized by short useful life and marginal insulating and weatherproofing ability, either because of limitations of the insulating fill (foam or fiber) or difficulty in sealing the seams or edges between adjacent tarpaulins. The disclosed tarpaulin comprises a first and second membrane sandwiching an insulating batt of a highly resilient fibrous glass insulation. The tarpaulin includes a seam structure around all four edges of the tarpaulin which not only fastens the first and second membranes together but holds the highly resilient fibrous insulating batt in position.
