Abstract: ABSTRACT          A segmented mold assembly is utilized to cast a turbine engine component having an annular inner wall and an annular outer wall which are interconnected by a plurality of struts or vanes.  The mold assembly includes a plurality of sections which are formed of a ceramic mold material and are interconnected at flange joints.  A pair of mold sections are advantageously formed simultaneously by repetitively dipping a single pattern in a slurry of liquid ceramic mold material to form a wet coating on the pattern.  This wet coating of ceramic mold material is then dried.  After a covering of the desired thickness has been built up by repetitively dipping and drying the coatings on the wax pattern, the wax pattern is destroyed.          To facilitate separating the mold sections after destroying the wax pattern, at least some of the wet coatings are wiped away in an area between portions of the wet coatings which will eventually form the mold sections.

Abstract: ABSTRACT OF THE DISCLOSURE           A terminal connection which will accept electrical conductors of various sizes and provides oxide breaking, spring loading, and conductor confining and bundling features.  A tab or finger on one of the terminal elements presses the conductor regardless of its size toward the other terminal element, and oxide breaking edges on one of the elements break oxide coatings on the conductor while the tab or finger both confines the conductor and forces it toward a mechanical operator such as a screw.  Forcing the conductor toward the screw reduces offset loading and permits additional oxide breaking by scraping the conductor with the screw as the screw is rotated to tighten the terminal.  In the case of a stranded conductor, the bundling obtained by forcing the conductor toward the screw assures good interstrand electrical contact, so that the electrical resistance at the connection is not significantly different from the resistance of a corresponding solid conductor.  In several embodiments, the tab or finger provides the spring loading or spring follow required to maintain good electrical and mechanical charac-teristics of the connection.  In some embodiments, a struck-out leg provides spring loading and the biting action for oxide breaking.

Abstract: "PROCESS FOR THE CONCENTRATION OF  MINERAL BY FLOTATION PROCESS"                ABSTRACT OF THE DISCLOSURE     It is possible to concentrate the mineral wolframite by the flotation process.  In this process, the ore is ground without using steel as a grinding medium.  When steel is used as a grinding medium, the grade of the wolframite flotation concen-trate is much lower. The ground ore is then aerated or condi-tioned vigorously with 2.00 lbs/ton of hydrofluosilisic acid or hydrofluoric acid or lactic acid more or less for a certain time period, followed by further aeration or conditioning with a tung-sten flotation collector HoeF 1415 (a phosphoric acid based col-lector), R-765 or an emulsified fatty acid or the like.  The aeration process aids the flotation of the coarser tungsten and decreases the consumption of the collector.  The wolframite rougher concentrate is then upgraded by using hydrofluosilisic acid or hydrofluoric acid in successive cleaning stages.  Des-liming the ground pulp prior to the addition of any reagents may enhance this flotation procedure.
