Abstract: A device for measuring tension exerted upon a thin, flexible, elongated, plastic bubble. The device utilizes a cylindrical air-bearing and a flow of air to concentrically and symmetrically deflect a portion of the bubble. By measuring the static pressure within the channel defined by the air bearing and the bubble, the tension forces on the bubble side walls in the longitudinal direction may be computed from known mathematical relationships characterizing thin-walled pressure vessels. The device is particularly useful for sensing tension fluctuations about a norm where the bubble is continuously moving and of indefinite length under a controlled manufacturing process.

Abstract: A thin, adherent coating is described that is highly absorptive to solar energy and has a low emissivity for thermal energy, thereby being a useful selective surface for solar energy collection. This coating is formed on aluminum and its alloys by a simple electrochemical process and consists of complex aluminum and molybdenum oxides and metallic molybdenum which are deposited as a near-monatomic layer of molybdenum and its oxides. The coating withstands exposure to 400.degree. F (204.degree. C) and 1 hour in boiling water without change in properties.

Abstract: An initially loose fitting aluminum sleeve is pre-tinned with fluxless solder and, while the solder is molten, is swaged down and rotated to form a tight soldered joint connecting two aluminum tube ends, or an aluminum tube end to a copper tube end.

Abstract: A hollow metal ball bat having a barrel of a relatively large diameter, a tapered intermediate portion and a handle portion of a relatively small diameter and method of making the same. The bat is formed from a metal tube, a section of which is initially enlarged in diameter and thereafter is drawn through an ironing die and then swaged down to an outside diameter smaller than the original tube diameter, to form the handle of the bat. An intermediate section of the tube is similarly reformed but to a tapered shape to provide an intermediate portion of the bat. The barrel of the bat may be left unchanged in the form of the original tube. The process can provide a completed bat having a substantially uniform wall thickness closely approximating the original wall thickness of the metal tube from which the bat is formed.

Abstract: 1. Armor possessing high resistance to penetration, comprising a metallic composite having a layer of aluminous metal bonded to a layer of a precipitation-hardenable ferrous alloy, said composite in bonded condition being susceptible to a thermal hardening treatment to increase the strength of said ferrous alloy layer.

Abstract: Casting apparatus comprising means for feeding molten material, a mold receiving the molten material in which the molten material solidifies forming a casting advancing through the mold, a cylinder, means including a piston operable in the cylinder ahead of the advancing casting limiting the speed of advance of the casting, means including a fluid pressure system for controlling the speed of advance of the piston in the cylinder by differential pressure on opposite ends of the piston, a control device settable for the desired speed of advance of the piston, a signal device responsive to the actual speed of advance of the piston and connections between the control device and the signal device determining said differential pressure to insure maintenance of the speed of advance of the piston at the desired speed.

Abstract: Improved alloy compositions for making sheet products, and related method aspects, based on adding zinc to Al-Mg alloys in an amount effective to avoid Type A Luder lines when cold working such sheet in annealed condition.

Abstract: Apparatus for holding a plurality of three panels in a window construction is provided and comprises a horizontally disposed rail having a substantially U-shaped channel for receiving a lower end portion of a first panel therewithin with the U-shaped channel being defined by a horizontal bight and a pair of vertically disposed legs including an inner leg and an outer leg extending from opposite ends of the bight and an extension extending horizontally from the central part of the inner leg with the horizontal extension cooperating with a portion of the inner leg thereabove to define a first L-shaped channel for receiving a second of the three panels therewithin with the rail also having a second L-shaped channel disposed beneath the first L-shaped channel which is adapted to receive a third panel therewithin and the holding means also includes at least one F-shaped clip adapted to engage and hold upper portions of the first and second panels in position.

Abstract: Carbon electrodes, either prebaked or Soderberg, made with coal or petroleum coke aggregate and an industrially stable binder that is derived from the entire organic fraction of bituminous coal and is suitable for manufacturing carbon electrodes according to existing industrial practice in the electrometallurgical industries. The binder is prepared by digesting the coal with a solvent to make a purified pitch, and industrial stability is imparted by fluxing the purified pitch at about 200.degree.-300.degree. C.

Abstract: A non-turbulent, level pour feeding of molten metal into a continuous-casting mold is provided through inlets formed in heat insulated blocks positioned at opposite shorter sides of the mold for casting large rectangular aluminum ingots. The heights of inlet passages are designed to clean impurities from molten metal. The longer sides of the mold are cooled to a higher level than the shorter sides.

Abstract: A rotary metal extrusion apparatus comprises a rotatable drum having a circumferential groove around its outer edge. A shoe, fixed relative to the drum, projects into the groove to form an elongated passageway having one end blocked by an abutment mounted in fixed relation to the shoe. The abutment has an extrusion orifice or die therein or adjacent thereto. The extrusion material is fed into the other end of the passageway and is drawn toward the die and abutment by frictional forces of the drum's groove. The pressure on the extrusion material causes its yield point to be exceeded so that the material is extruded through the die orifice. The portion of the shoe which is in sliding contact with the drum comprises a bearing material to allow sliding contact with the drum surface and reduction of flash through the space between the shoe and the drum.
