Abstract: A polymeric coating composition for use in overlaying at least a portion of a substrate element composed of a plural component polymeric system composed of a reactive blend of at least one first component and at least one second component, wherein the first component essentially of a polymer and/or blend of polymers present in an amount sufficient to impart a predetermined amount of tensile strength, hardness, flexibility and adhesive strength to the resulting polymeric coating, and the second component is an isocyanate or isocyanate quasi-prepolymer. The substrate element is a blast-resistant polymeric material having low surface energy and/or low reactivity at or near the surface of the substrate. Also disclosed is a blast and/or ballistic-resistant construction element composed of a structure having the aforementioned polymeric material thereover. The polymeric material has a substrate matrix containing at least one of ultrahigh molecular weight polyethylene, aramid materials, and the like.

Abstract: An articulating joint is provided for use in a foldable frame for a stretcher for example, which is capable of being selectively locked against upward, downward, or lateral folding by rotating the joint relative to the folding frame member.

Abstract: This invention is an advancement in the safe and practical methods of transporting sick or injured patients. The Manhandler is a flexible stretcher constructed of pliable materials. The injured patient is firmly secured to the cot portion of the system by a flexible wrap of sturdy material that extends along each side of the patient's entire body and is secured across his body by a series of strong straps. The litter and the wrap are attached to two parallel flexible strips of material which form lifting grips. These side grips provide support when lifted from the side. A solid sheet of plastic material provides rigidity to the cot portion of the stretcher when side lift is applied, yet remains flexible to allow elevation of the feet and head when such lift is released. The supporting material is radio-opaque to allow x-rays without the necessity of removing the patient from the litter.
