摘要： A multi-use variable guard rail system for providing a safe working area is mountable on various surfaces, whether sloped (roofs), vertical (walls) or horizontal (floors). A rail support of the system has an upright pivotally engaged with a base, and a brace that locks the upright relative to the base in numerous positions ranging between an acute angle and an obtuse angle where the upright and base are linearly aligned. The upright has openings that hold rails such as various sizes of lumber in a vertically stacked array without the need to cut or fasten the lumber, and which allows for replacement of rails without disassembly of the rest of the system. The base has a tongue particularly suited for roof work, namely it is used to mount the rail support to the roof, yet allows the base to be lifted for placing shingles thereunder.

摘要： A concrete form including a rigid substrate having at least one of a flat and curved surface, which are presented to poured concrete, and a flexible membrane lining at least the one flat or curved surface of the rigid substrate so as to have at least one flat or curved surface due to the respective flat or curved surface of the rigid substrate. In some embodiments, at least a portion of the flexible membrane comes into contact with the poured concrete, whereupon the cured concrete may be separated from the concrete form, in the absence of a release agent, to provide one or more corresponding flat or curved surfaces on the cured concrete, which surfaces require little to no finishing work.

摘要： Capsaicinoids that repel insects, reptiles, mammals, microorganisms and marine life are compounded with one or more ceramics or other inert material, into an environmentally friendly additive. The additive can be incorporated by extrusion, pultrusion, compression molding, casting or other suitable process into a wide range of products including, but not limited to, polymers, composites, paints, coatings, varnishes, shellacs, stains, sealants, preservatives, glues, adhesives, minerals, resins, latex, reinforced polymers, powders, foams and other similar classes of materials polymers, or combinations thereof. The repellency of the capsaicinoids remains effective for periods up to several years when the products are employed in their normal commercial uses.
