Abstract: Method and apparatus for the production of wall members of an inflated wall shelter or the like.  A continuous tubular plastic is supplied from a supply roll and wound around an elongated winding section having two end rolls, the distance between the two rolls being preferably equal to one-half of the desired breadth of the final wall product, or equal to integral multiples of the desired breadth.  The tubular plastic supplied from the supply roll is provided with a continuous strip of a predetermined breadth of adhesive on its surface prior to entering the winding area, the adhesive strip defining the joint between adjacent plastic "tubes".  When appropriate number of convolutes (depending on the desired length of the final product) is wound up, the supply of the tubular plastic is cut off and the wound product is cut, preferably along a line parallel with the axis of the end rolls, and the resulting stack is removed from the winding section.  Finally, a rod is inserted into each of the top and bottom plastic tubes of the stack.  by pulling the rods apart, the stack can be "unfolded" or spread to its entire length, thus obtaining a shelter wall structure having a plurality of side-by-side tubes with adjacent tubes being joined by the adhesive strip.

Abstract: ABSTRACT A nozzle assembly for atomizing a stream of molten metal includes a refractory metal-transmitting nozzle having a short metering orifice at its entrance end and a relatively long diver-gent discharge passage terminating at a flat annular land formed at the bottom end of the metal-transmitting nozzle.  The metal-transmitting nozzle is seated in an opening in the bottom of a tundish or other source of molten metal with its upper end containing its metering orifice projecting into the molten metal reservoir. The lower-end portion projects from the bottom of the tundish and through the central portion of an atomizing fluid nozzle assembly in which it seats.  The central portion of the atomizing fluid nozzle assembly projects below the bottom member of the atomizing fluid nozzle assembly and forms an atomizing fluid orifice there-with.          The process of utilizing the apparatus for atomizing powder is described in which a molten metal film is formed around the outer bottom portion of the metal-transmitting nozzle which extends below the central portion and orifice of the atomizing fluid nozzle assembly.
