Abstract: Load lifting and transporting apparatus which comprises plural individual units that can be combined into a configuration corresponding to the configuration of the load. There are load lifting units equipped with a jack screw and there are load engaging units equipped with plates for engaging the load. Each of the units is provided with sleeves through which elongate bars can be introduced to retain the lifting and engaging units in a framework surrounding the load. The load engaging units can be provided in various forms such as a unit with a plate that can be positioned beneath the periphery of a rigid load, a unit having flexible belts or the like that can be passed beneath irregularly shaped loads, a unit specifically adapted to pass beneath the wheels of a vehicle, and a unit including a truss that can be positioned above a load.

Abstract: A one-piece blank which may be formed into a liquid-tight carton is T-shaped and is comprised of side wall panels integrally interconnected and numbering three or more to provide a carton of polygonal cross section. One of the side wall panels has integrally connected carton end closure panels to be folded down upon and sealed to sealing tabs of the other side panels after the blank has been formed by a side-seam operation into an open-ended tube. The end closure panels are of substantially the same area as the cross-sectional area of the carton but are not provided with sealing flaps. They are embossed marginally around their free edges to provide a curvature for contact with the sealing tabs when the ends of the carton are closed by rendering the closure panels and the sealing tabs mutually adhesive and pressing the closure panels down upon the sealing tabs.

Abstract: A frame having two or more thin elongate vanes mounted thereon and a shaft for supporting the frame for rotation so that each of the two opposite surfaces of the vanes is sequentially exposed to heat energy from the sun or the like. One surface is an absorbtive surface, exposure of which effects heating and expansion of the vane. The other surface is reflective surface, exposure of which permits cooling and contraction of the vane. When the vane contracts, the contraction sets up substantial tensile forces within the vane, and the invention includes a linkage interlinking the vane and the shaft so that the tensile force is converted to rotative force to sustain rotation of the frame. The frame has a power takeoff so that useful work is produced.Two mechanisms for interlinking the tensile force in the vanes to rotative motion are disclosed.

Abstract: A one-piece blank which may be formed into a liquid-tight carton is T shaped and is comprised of side wall panels integrally interconnected and numbering three or more to provide a carton of polygonal cross section. One of the side wall panels has integrally connected carbon end closure panels to be folded down upon and sealed to sealing tabs of the other side panels after the blank has been formed by a side-seam operation into an open-ended tube. The end closure panels are of substantially the same area as the cross-sectional area of the carton but are not provided with sealing flaps. They are embossed marginally around their free edges to provide a curvature for contact with the sealing tabs when the ends of the carton are closed by rendering the closure panels and the sealing tabs mutually adhesive and pressing the closure panels down upon the sealing tabs.
