Abstract: A system of pre-formed panels, trusses, and roof elements, configured so as to affix to and integrate with one another to form a building structure. The truss elements are independently supported by columns. The several wall panel frames are attached to said support columns, to each other, and to the foundation of the structure. The roof panel frames are attached to the walls, to the trusses, and to each other. The entirety forms an integrated structure of substantial strength.Each wall panel frame is pre-formed so as to, after erection of the structure frame, receive exterior sheeting, in half-standard sheet sizes, within its outer frame, said sheeting being rigidly affixed to said panel frame. Similarly, interior sheeting is affixed to the inner side of the said panel frame, and insulation may be introduced between the two sheets. Exterior sheeting is similarly affixed to the roof panel frames, which is subsequently overlaid with standard roofing materials.

Abstract: This invention presents a face shield for beach or sunbathing use. The face shield is formed of a rigid transparent material, containing pigmenting or surface films to block the transmission of damaging ultraviolet rays from the sun. In cross-section, this material is formed into an arc. From each end of the arc, simple support legs are provided such that the face shield will rest on the earth surface with room for motion of the user's head beneath the shield. Air circulation is enhanced by such support and by ventilation holes in the face shield near the support legs. The support legs are foldable toward the concave center of the face shield, and are useful as carrying handles for the face shield in an inverted position. When carried in such manner, the face shield can be used to serve as a "tote" for towels and other beach paraphernalia.

Abstract: A color television projection system that optically combines the outputs of three small cathode ray tubes, each projecting an image in one of three primary colors, to produce a full-color image that is not subject to the usual "color matrix" losses experienced by contemporary television receiver units. This system employs a solid optical system, similar to a classical Schmidt system, but modified by having the necessary colored beamsplitters immersed, as part of the fabrication process, within the solid optics near the primary focal plane to serve as the aperture stop for the system, and further modified by having an air separated corrector lens. Additional light energy efficiency, over contemporary techniques, is obtained by having the cathode ray tube faces immersed within the solid optics and optically coupled thereto by an appropriate optical bonding agent.

Abstract: A table-tray combination having a foldable supporting structure consisting of a pair of legs, held in a vertical position by bases pivoted from the lower ends of each leg and locked in place by slotted braces and detent studs. An arm frame, pivoted from the upper middle region of each leg, forms, together with the upper ends of the legs, the plane to which the detachable tray is clipped. When the bases and arm frame are folded for storage, the structure and tray assume an essentially flat shape. Clips, rigidly attached to each leg, hold the folded structure for storage and preclude opening them improperly.
