Abstract: ABSTRACT OF THE DISCLOSURE         Sintered ceramic articles having a high surface area-to-weight ratio and containing a plurality of ducts that extend through the article to permit fluid flow therethrough are prepared by forming an extrudable ad-mixture of pulverized ceramic material. The admixture is forced through a forming zone in which initial shearing forces form the admixture into a plurality of discrete ribbons, and the discrete ribbons are flowed into the upstream ends of a plurality of spaced, longitudinally-extending members to form a web member containing a plurality of longitudinally-extending ducts as the ribbons flow together about the members. Monolithic ceramic structures formed by the above-described process and including, hexagonally-packed circular ducts, that is, circular ducts surrounded by six other circular ducts with each surrounding duct spaced an approximately equal distance from the axis of the circular duct it surrounds, exhibit a desirably high ratio of transverse compressive strength to longitudinal compressive strength.     1.

Abstract: ABSTRACT OF THE DISCLOSURE Herein disclosed is a molded article of a synthetic resin having on its smooth surface a decorative pattern which is viewable as a stereo-scopic image from the outside,  remolded article includes a substratum which forms the general structure of the molded article and which is molded of a material consisting essentially of a synthetic resin and an additive. The article further includes a decorative surface layer which is formed on the substratum in a manner to provide a generally smooth finish.  This decorative surface layer is composed both of a decorative pattern portion figured by the flow marks inside of the trace of a relief pattern, which has once been formed during the molding process of the article, and of a ground portion.  The decorative surface layer is made during the molding process integrally with and of the same material as that of the substratum.  Thus, the decorative pattern portion can appear stereoscopic, although having a smooth surface, just in the form of the relief pattern as a result of the shading due to substantially radial reflection of the light incident upon the flow marks.  In  a modification, the molded article may have at least one covering layer which is formed by a second molding process of a similar material but has a different appearance.  Then, the article thus modified has a stereoscopic decorative pattern which can enjoy multiple appearances. Also disclosed is a process for fabricating such a molded article as above.

Abstract: ABSTRACT      A process is disclosed for recovering purified glass from solid waste which includes a predominantly organic fraction and a predominantly inorganic fraction both of which contain glass particles.  The predominantly inorganic fraction is further subdivided into a glass-rich fraction containing glass, inorganic, and organic constituents.  The organic constituents are initially separated from the glass-rich fraction.  The organics-free fraction is comminuted and screened to remove coarse particles greater than a first predetermined mesh ?. The residue is classified to remove fine particles less than a second mesh size.  The resultant mixture, after removal of coarse and fine particles, is subjected to froth flotation to form a float containing predominantly glass which is recovered for further use.
