Abstract: THERMAL ENERGY STORAGE DEVICE AND METHOD FOR MAKING THE SAME ABSTRACT: A thermal energy storage device and method for making the same. The thermal energy storage device is in the form of a sealed tube-like container such as a tube-like cylinder or other geometrical configuration partially filled with a phase change material such as calcium chloride hexahydrate. The cylinder is made of tubular high density polyethylene and more particularly an ultra high molecular weight high density polyethylene having a molecular weight of about 500,000 to 700,000 which is touch, chemically resistant, withstands low and high temperatures, acts as a moisture vapor barrier and can be fused and sealed. The calcium hexahydrate is filled in an open top cylinder, closed at the bottom by dissolving two parts of calcium chloride dihydrate with one part of. water to provide calcium chloride hexahydrate in liquid form. The cylinder is filled to about 90% by volume and a cap of the same ma-terial is then preheated to about fusion temperature. The open top of the cylinder is then brought up to fusion temperature and the cap is fused to it under pressure. The thermal energy storage device with the encapsulated calcium chloride hexahydrate can then be subjected to repeated freeze-thaw cycles. The latent heat of fusion is utilized with sensible heat in various types of usages such as solar heating, heat pump applications and the like. In another embodiment the cylinder may be pinch sealed at the bottom and top by fusion to provide a flat pinch. Modifications of pinch sealing to reduce distortion near the seal include X-shaped, V-shaped and wave-shaped pinch seal configuration. The tube-like container instead of being cylindrical may for case in stacking and to present greater surface area take other geometrical configurations such as a generally oblong configuration with rounded sides.

Abstract: Abstract Disclosed is a multiple target scanning electron beam X-ray source for use in high speed multiple section computed-tomographic (CT) X-ray transmission scanners.  The scanner uses a single electron beam tube.  The electron beam is rotated by a magnetic deflection system.  The electronic scan-ning system is much faster than mechanical scanners and requires no moving parts that require high precision and alignment.  It also eliminates elaborate systems of sliding electrical contacts.  The system includes an electron beam scan tube having a cylindrical end portion with an electron gun and a semi-circular portion.  The electron beam is focussed and bent to direct it into the semi-circular portion and scan it in a semi-circular over X-ray generating target rings.  Collimators adjacent the target rings provide a fan-shaped X-ray beam which rotates as the electron beam is moved along the target rings.

Abstract: ABSTRACT            "Method and apparatus for applying decals to articles"     This disclosure relates to a method and machine for applying a decal to a generally cylindrical article, par-ticularly an article having a handle on one side thereof. A series of decals are attached to an elongated web and are spaced a generally constant distance apart in the direction of the length of the web.  The machine includes supply and take-up spindles for rotatably supporting reels for the web, and a web drive for moving the web from the supply reel to the take-up reel.  A mandrel rotatably supports the article and a movable head presses the web and the decal against an article on  the mandrel.  The web passes from the supply reel, between the mandrel and the head, and to the take-up reel.  The machine further includes a brake which, when engaged, holds the web against movement, and a decal sensor assembly.  After the machine is actuated to cause the movable head to press the decal against an article, the brake is actuated to release the web, and the web is then pulled across the article.  The moving web rotates the head which in turn engages and rotates the mandrel.  The article revolves with the mandrel and the decal is rolled onto the article.  The decal sensor assembly controls the operation of the brake to enable advance of the web during and after application of each decal.
