Abstract: Abstract of the Disclosure An electric melting furnace is provided for optimally melting and mixing a non-homogenous material.  The melting furnace includes a vessel  having  its  top  portion  open  to  the  environment.  Three electrodes are supported above the furnace.  Each of the electrodes includes  a  tip  for  insertion  into  the material  contained  in  the vessel  The vessel further  includes  an outlet  formed  in the  bottom wall  of the vessel to discharge the material after it  has  been  melted and optimally mixed.  Each of the three electrode tips has a generally round configuration.  During the melting operation, the three electrode tips are laterally spaced from each other and are positioned in the vessel to be surrounded by molten material but above the bottom wall outlet.  Optimum melting and then optimum mixing of the material occurs at selected horizontal spacings of the electrode tips and at selected electrode tip immersions in the molten material.  The lateral spacing of the electrode tips and the immersion thereof depends upon a number of conditions including the width or diameter of the vessel, the magnitude of power  applied to the electrodes, and the desired temperature of the molten material contained in the vessel.

Abstract: HEAVY DUTY WEIGH SCALE     ABSTRACT OF THE DISCLOSURE         The weigh scale incorporates a weighbridge, load cells and load cell mounting mechanisms for each load cell.          The load cells are double ended shear beam type horizontal-ly mounted directly under the main beams of the weighbridge with the ends of the load cells being rigidly secured to a load cell stand which in turn is supported upon the con-crete base of the weigh scale location.  The load is ver-tically applied to the load cell by means of a chair for each load cell and a link plate.  Each of the sides or legs of the chair rest upon the supporting means of the link plate which in turn applies a vertical shearing force upon the load cell intermediate the ends thereof.  The support points or areas of the link plate are located below the engagement point or area of the link plate upon the load cell and this permits free horizontal movement of the weighbridge longitudinally, but absorbs any side movement thereof without affecting the conventional electronic in-dicator to which the load cells are operatively connected.

Abstract: ABSTRACT      Tungsten is recovered from tungsten ore concentrates in the form of sodium tungstate by a basic process in which ground ore is first digested in a sodium hydroxide solution followed by diluting the solution to dissolved sodium tungstate separating the solution from the caustic insoluble sludge and crystallizing soluble sodium tung-state, wherein the present invention permits improved recovery of tungsten from difficult to process ores by the process steps of comminuting said tungsten ore con-centrate to a particle size less than about 200 mesh, adding the comminuted ore to an aqueous solution of sodium hydroxide at a temperature from about 10 to about 30 degrees centigrade, dispersing said comminuted ore in the aqueous solution of sodium hydroxide prior to diges-tion, digesting at a temperature of from about 75°C to about 150°C for a sufficient period of time to convert substantially all of the tungsten values to dissolvable sodium tungstate, and diluting the mixture to reduce the sodium hydroxide concentration to between about 4.5 and 5.5 molar at a temperature below about 90°C to substan-tially dissolve all of the sodium tungstate.

Abstract: ABSTRACT     An improved safety pressure relief valve which is particu-larly applicable to valves utilizing pressure taps for sensing the pressure within the inlet nozzle, such as pilot operated valves.        The valve includes a valve body having an inlet opening into which a full nozzle is inserted.  An annular port surrounds the peri-phery of the nozzle. An opening in the nozzle leading to the annular port provides for the insertion of a pitot or dipper tube therein.  The valve body includes a channel leading between the annular port and an external tap for the pressure sensing line connected to the pilot control means.  The design permits the nozzle to be rotated to any angular position with respect to the valve body, thus permitting ready assembly and disassembly of the valve.  In a second embodiment, an annular port is used to permit direct injection of purging fluid into the nozzle to prevent its clogging.

Abstract: FLUORESCENCE LASER EXAFS            ABSTRACT         Apparatus (10) for obtaining fluorescence laser EXAFS (Extended X-ray Absorption Fine Structure).  A lens (12) directs a pulse of radiant energy (13) onto a metal target (15) to produce X-rays (16). A baffle (17) directs the X-rays (16) onto a spectral-dispersive monochromator (18) which directs the spectrally-resolved X-rays (16R) therefrom onto a sample (11).  Fluorescence X-rays (27) from the sample (11) strike a phosphor (26) on a grid (19).  Emitted light (21) from the phosphor (26) corresponds spatially to the spectral resolution of the X-rays (16R).          Emitted light intensity at a point along the spatial distribution corresponds to the absorption character-istics of the sample (11) at a particular wavelength of the incoming X-rays (16R).  An imaging lens (20) directs the emitted light (21) onto photographic film or an array detector (22).  A reference spectrum of the spectral-ly-resolved X rays (16R) is obtained by placing photo-graphic film or an array detector (29) in the path of the spectrally-resolved X-rays (16R) so that only a portion of the X-rays (16R) throughout the spectrum strikes the film or array detector with the remaining portion throughout the spectrum allowed to pass to the sample (11).

Abstract: METHOD FOR FORMING VIDEO DISCS               ABSTRACT OF THE DISCLOSURE      Methods for use in producing a disc-shaped recording master having a thin photoresist recording layer for storing an f.m. information signal with high density.  During recording, an intensity-modulated writing beam is focused onto the photoresist layer, to form a succession of spaced exposed regions arranged in a plurality of substantially cir-cular and concentric recording tracks.  The master further includes a glass substrate having a specially prepared surface, and the photoresist layer is deposited on the surface using a technique that ensures a uniform thickness and a uniform sensitivity to the writing beam.  The peak intensity of the writing beam is selectively adjusted such that the succession of spaced exposed regions is formed with an optimum 50/50 duty cycle. After development to remove the spaced exposed regions, the recording master is used to produce a metallic stamper that, in turn, is used to produce disc replicas.  Developing is effected by first dispensing water on the photoresist layer to pre-wet it, then both water and developer solution are dispensed and finally developer solution alone.

Abstract: ABSTRACT OF THE DISCLOSURE           The present  invention  relates  to sulfonated elastomeric polymers which are copolymers of isoprene and sodium styrene sulfonate or teropolymers of isoprene, styrene and sodium styrene sulfonate wherein these sulfonated polymers function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells.   The sulfonated and elastomeric polymers have 5 to 100 meg. of sulfonate groups per 100 grams of the sulfonated elastomeric polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion.  A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated elastomeric polymer, wherein the polar cosolvent increases the solubility of the sulfonated elastomeric polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.
