Abstract: A structural solar energy collection and transfer arrangement and method, and method of assembly, including an insulating light-transmitting honeycomb sandwich array and a lateral fluid flow solar energy collection and heat transfer honeycomb sandwich array, the lateral fluid flow honeycomb sandwich array having dark, preferably non-gloss or dull surfaced, honeycomb walls and bottom surface for solar energy absorption and transfer to a fluid, preferably a liquid, passed laterally through fluid passageway openings formed in the honeycomb walls. Solar energy is absorbed and transferred to a flowing fluid, by passing solar light rays through the insulating honeycomb sandwich array and into contact with the dark walls and base of the facially interconnected heat transfer honeycomb sandwich array, and passing the heat transfer fluid through the lateral openings formed in the honeycomb cell walls and thereby flowing such fluid through adjacent honeycomb cells.

Abstract: A high density armor piercing projectile having a cylindrically-shaped penetrator core. The core has a length substantially greater than the diameter thereof. Encompassing the penetrator is a carrier body and nose. The carrier body being press fit on the penetrator core and having a stabilizing ring press fit thereon. An obturator and pusher plate are secured to the rear of the penetrator core. In addition, the design of the carrier body enables the projectile to be spin stabilized when fired from any suitable weapon.

Abstract: A solar energy concentrating and collecting arrangement and method in which a semi-cylindrical oblong concave reflector/concentrator forms the roof of a house, school or other building, particularly a heat utilization building. A collector is movably supported in spaced relation above and along the length of the oblong roof/reflector concentrator, for pivotal movement, by a solar reflection energy sensing and seeking drive control arrangement, to a zone of maximum confluence of solar energy rays reflected from the roof/reflector concentrator as a result of variations of sun path during the various parts of the year and also to further accommodate each day's movement of the sun. Movement of the collector is by pivotal movement about an axis parallel with the center of curvature or curvatures of the roof/reflector concentrator and disposed adjacent the roof/reflector concentrator.
