Abstract: F. 011 (Amax 969) CHEMICAL TREATMENT OF LOW-GRADE WOLFRAMITE    CONCENTRATE HAVING HIGH Mo/WO3 RATIO     ABSTRACT OF DISCLOSURE     A process is disclosed for recovering tungsten and molybdenum values from tungsten concentrates containing molybdenum in an amount at least about one-twentieth of the amount of con-tained WO3.  The concentrate, generally a wolframite concentrate, is subjected to dissolution in hot NaOH solution to provide a pregnant liquor or solution containing tungsten and molybdenum values.  The solution, after purification; is treated with a sulfide precipitation agent to precipitate MoS3 and some WS3 using a stoichiometric excess of a sulfide precipitating agent to produce a filtrate containing tungsten substantially free of molybdenum.  The sulfide precipitate is dissolved in dilute NaOH solution and again precipitated using a stoichiometric deficient amount of the sulfide precipitating agent to produce a precipitate of MoS3 low in tungsten.  The foregoing sulfide precipitation steps may be reversed.

Abstract: TITLE:  AUTOMOTIVE FLOOR MAT HAVING RIGID RIB         ABSTRACT OF THE DISCLOSURE           A floor mat for an automotive vehicle is provided having a relatively thin, flexible sheet-form main body and a rigidifying rib structure formed with or secured thereto in fixed relationship.  The rigidifying rib structure is fabricated from or formed by elongated elements that are effectively rigid and thereby render the otherwise flexible main body essentially inflexible.  The materials selected to form the rib structure preferably have a resilient characteristic, such as spring steel wire rod, to enhance the mat's ability to maintain itself in a desired smooth, flat configuration on a vehicle's floor. The rib structure is of a configuration to rigidify the main body in two generally perpendicular directions to resist displacement in all directions through the essential rigid rib encountering of any obstructions associated with the vehicle floor and the resilient characteristic of the rib accommodating excessive displacing forces and tending to return the main body of the mat to its original configuration. The rib elements may be rod-like elements or flat strips either integrally embedded in or formed with the sheet-form main body or they may be mechanically secured thereto.

Abstract: ABSTRACT           A cutting member for rotary drill bits for deep-well drilling in ground formations consists of a carrier member with a supporting surface and a supporting member of hard metal rigidly connected to this at its back with a cutting layer of polycrystalline synthetic diamond material.  The supporting member together with its cutting layer is cut out of a circular cylindrical shaped body or made as a segment and together with its cutting layer occupies only a portion of the supporting surface of the carrier member, the remaining supporting surface being occupied by a supplementary member of hard metal or other high-strength substances.  With regard to the cutting performance and effect, the same requirements are met as with a circular diamond cutting plate while at the same time considerable savings are achieved in valuable diamond material.

Abstract: DUAL HEAD MEASURING TECHNIQUES FOR RADIATION GAGING OF   REINFORCING BAR     Abstract of the Disclosure A continuously measuring on-line production gage calibrated to indicate bar weight per foot and unaffected by typical reinforcing bar shape variability utilizes two radiation gages with their measuring axes separated by 90 degrees and offset by 45 degrees from the rib plane of the reinforcing bar.  Each gage is equipped with a shutter which may be adjusted electrically to simulate any required weight per foot standard and with the gage zeroing on a predetermined shutter setting, the shutter automatically opens and radiation detector signal variations from the zero point are amplified, linearized, averaged, and scaled electronically to produce a percent weight per foot output signal.  Summation of detected radiation is also performed through use of optical fibers.

Abstract: PRECISE POSITIONING OF OPTICAL FIBERS             Abstract of the Disclosure Before splicing optical fibers having cladding and core of differing refractive index, the cores are axially aligned.  The fiber ends are held apart with the fibers approximately coaxial.  The fiber end surfaces are then illuminated and reflected light is monitored.  Since reflectivity is d function of refractive index, the position of the core in the reflectivity profile of each surface can be readily identified.  The fiber ends can then be manouvered transverse of the fiber axes to bring the fiber core centers into registration with a datum line.  The fiber ends are then brought close together for splicing.  Previously, fibers having nominally identical outside diameters were aligned simply by pressing them into a common V groove, the optical transmission efficiency then depending on fiber/core concentricity.  Alternatively, light was injected into the far end of one fiber, monitored at the far end of the other fiber, and the fibers at their near end manipulated to maximize monitored optical power.  The present invention provides an easier and cheaper method of ensuring core alignment especially for monomode fibers.    - i -

Abstract: ABSTRACT          This invention relates to a detection system for determining the lateral weave or sinosoidal variation in the edges of a continuous strip of sheet metal during an uncoiling and coiling operation.  The detection of the weave permits prompt corrective action to be taken. The system comprises an apparatus positioned along one edge of the line on which the coil is being processed after the sheet exits a rotary cutting knife.  It operates to scan the edges of the sheet for lateral weave from the center line of the rotary shear.
