Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE          A disposable container suitable for retaining liquids comprises two opposed container sections, each having a peripheral ring like flange about a recess with the flanges being sealed therebetween.  The recesses of the opposed container sections define a common central cavity and the flanges include a throat opening into said cavity through which product within the cavity can be dispensed.  The throat is at least partially defined by the opposed container flanges and each container section is of a thermoformable plastic material.  These container sections are originally formed from flat strip packaging material having diecut side edges with the strip defining individual container body sections.  A tapered neck portion of each body section accomodates dispensing of the contents and preferably a hot melt adhesive secures the opposed container sections.  The plastic containers are formed by intermittently advancing, in timed sequence, two strips through separate thermoforming operations where each strip is shaped to form a series of half containers and thereafter the strips are married and secured for subsequent operations.  The invention also includes an apparatus and process for forming, filling and sealing the containers by advancing the packaging material through a number of stations along a predetermined path.  The formed container is shaped to reduce inadvertent tipping thereof when supported in a free-standing disposition.

Abstract: ABSTRACT A method and apparatus for the sequential casting of steel strip in steel strip casting equipment wherein under normal operating conditions a steel melt is fed through a pouring tube having discharge ports into the pouring area of a cooled ingot mold at a location below the surface of the melt in the mold and is thereafter removed from the mold in the form of steel strip by the combined operation of mold oscillation means and strip discharge means.  After the feed of melt is interrupted, anchoring rods are partially longitudinally immersed into the melt laterally of the pouring area of the mold, and the surface of the melt in the mold is lowered to a level below the pouring area.  After a desired interval, the melt feed is continued, and the level of the surface of the melt in the mold is allowed to rise above the discharge ports of the pouring tube.  Thereafter, casting flux is applied to the surface of the melt, and the operation of the mold oscillation means and the strip discharge means is resumed.  The method also includes the steps of restarting the feed of melt through the pouring tube after a desired interval; allowing the level of the melt in the cavity of the mold to rise above the discharge opening of the pouring tube; thereafter applying a layer of casting flux to the surface of the melt in the mold; and restarting the strip discharge means and the mold oscillation means such that the original level of melt in the cavity in the mold is reestablished and maintained.
