Abstract: ABSTRACT OF THE DISCLOSURE          A process for the metallurgical treatment of pyroxenite-type ore, which comprises comminuting the ore to a particle size range of between about 40 and 600 micron, or alternatively between about 40 to 1000 micron, and thereafter subjecting the comminuted ore to dry HIMS to recover a non-attracted apatite concentrate from weakly attracted silicate minerals contained in the proxenite ore.  Another aspect of the invention relates to the recovery of phlogopite and/or vermiculite from more weakly attracted diopside and non-attracted apatite by dry HIMS.   A further aspect of the invention relates to particle size fractionation  by pneumatic classification followed by dry HIMS, electrostatic separation and dry HIMS, and electrostatic separation alone, applied res-pectively to fine, medium, and coarse particle size fractions respectively to recover apatite from sili-cate minerals contained in pyroxenite ore.

Abstract: ABSTRACT OF THE DISCLOSURE            Racking mechanism for a draw-out circuit breaker movable into and out of a cubicle wherein a hook at the rear of the cubicle is engaged by a pin on the circuit breaker structure; the pin is connected by links to a travelling nut on a racking shaft extending in the circuit breaker in the direction of movement of the circuit breaker; rotation of the shaft in one direction causes the pin to enter the hook and then, through the travelling nut, draw the racking shaft and hence the circuit breaker toward the rear of the cubicle.  Rotation of the racking shaft in the opposite direction causes the racking shaft and circuit breaker to move away from the rear of the cubicle.  On pre-determined movement toward the front of the cubicle, the pin is disengaged from the hook to permit with drawal of the circuit breaker from the cubicle.

Abstract: Case 2673 FUSS CLIP A CARTRIDGE FUSEHOLDER      ABSTRACT OF THE DISCLOSURE       A fuseholder assembly for a fusible loadcenter is described.  The assembly comprises a fuse unit and a base member.  The fuse unit includes a pair of spaced apart U shaped fuse clips axially aligned about the longitudinal axis of a cartridge fuse.  The fuse clips each have two mutually opposed wing contact portions that are substantially parallel to the longitudinal axis. The broad contacting surface area of the wing contact portions are capable of making contact with a load or line contact.  The base member has an opening therein for receiving the fuse unit.  The base mmeber has a load and line contact each of which includes a base portion and two resilient side strips that are closely adjacent to each other.  Each side strip is independently biased to-wards the opening in the base member and lies on a plane normal to the longitudinal axis.  Each broad surface area of the wing portions makes wiping electrical contact with a smooth contact surface of a corresponding independently biased side strip when the fuse unit is inserted in the opening of the base member.  Previous fuseholder assemblies have a heat producing joint where the contacts join the legs of the fuse clips.  The present fuseholder eliminates this heat producing joints by forming the wind contact portion from the legs of the fuse clips.  The present assembly also compensates for discrepencies in the lengths of mutually opposed contacts by providing two independently biased side strips.

Abstract: Abstract A method for forming an insulator between conductive layers, such as highly doped polycrystalline silicon, that involves first forming a conductive layer of, for example, polycrystalline silicon on a silicon body having substantially horizontal and substantially vertical surfaces.  A conformal insulator layer is formed on the substantially horizontal and sub-stantially horizontal and vertical surfaces. Reactive ion etching removes the insulator from the horizontal layer and provides a narrow dimensioned insulator on the vertical surfaces silicon body.  Another conductive layer, which may be polycrystalline silicon, is formed over the insulator.  The vertical layer dimension is adjusted depending upon the original thickness of the conformal insulator layer applied.

Abstract: ABSTRACT OF THE DISCLOSURE An improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides.  In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture.  The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent.  There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system.  The improvement to the adsorbent and process comprises the incorporation of a binder material in the adsorbent comprising a water permeable organic polymer which is substantially reduces the undesirable dissolution.  The adsorbent is manufactured by mixing together powder of the crystalline aluminosilicate, powders of the organic polymer binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate.
