Abstract: ABSTRACT OF THE DISCLOSURE         A method for separating hafnium and zirconium is disclosed in which unseparated zirconium  and hafnium are dissolved in the molten state in a solvent metal, preferably zinc.  This molten metal phase is contacted with a fused salt phase which includes a zirconium salt as one of its components. The desired separation is effected by mutual displacement, with hafnium being transported from the molten metal phase to the fused salt phase, replacing zirconium in the salt, while zirconium is transported from the fused salt phase to the molten metal phase.  Separation factors of 300 or more per stage are achieved.

Abstract: TV GAME APPARATUS Abstract of the Disclosure A TV-type game employs a raster screen television for presenting of game symbols.  Player operated control switches are encoded to move the symbols.  A microprocessor reads the switches.  A dually addressed random access memory is employed as the interfacing between the screen and the processor which otherwise function as essentially separate and distinct devices.  The memory provides a static storage of the screen pattern for each point in the raster lines with a portion assigned as a processor scratch pad.  The memory may be dynamic with periodic refreshing and constructed with individual chips for each of the several bits in a word. The chips are grouped for alternate refreshing and powered during access periods.  The processor updates the memory during idle display access periods.  The memory is accessed in multiple bits words or bytes for display and processing. For display, a parallel to serial output latch is employed. The previous symbol position and pose is stored in the scratch pad and is erased and rewritten in a new position and pose. The controls may provide encoding.  A hardwired bit shifter with programmed shift level rapidly shifts the symbol bits before placing in memory.  A high speed memory and low speed processor are shown with separate clocks and a special syn-chronizer unit.

Abstract: ABSTRACT OF THE DISCLOSURE         A feed stock comprising sugar, milk solids, a signi-ficant amount of moisture, and in some instances chocolate, is raised to a temperature of about  125°   C. and at the same time is condensed to have a moisture content of between about 4% and 6%.  This is done by moving the material upwardly in an annular column and heating the walls defining that annular column.  The condensed material is maintained at its final temperature and transferred to a crystallizer.  In the crystal-lizer it is moved downwardly and kneaded.  The kneading is per-formed by two sets of interdigitating rods, one set being stationary and the other set moving transversely to the down-ward path of movement of the material.  As it is being kneaded it is cooled, both by contact with refrigerated surface and also by a countercurrent flow of cool air.  The kneading is continued until the product is crystallized and particulate. Thereafter, it is optionally dried to a moisture content of about 1%.

Abstract: ABSTRACT OF THE DISCLOSURE A nomograph type calculator which will use skinfold data and informa-tion relating to the actual body weight of a person to enable a person's ideal body weight to be determined.  The nomograph comprises an elongated outer housing having open ends and a flat, translucent front face with a plurality of elongated, spaced, rectangular transparent windows therein.  An indicator plate is slidable longitudinally within the housing adjacent the inner surface of the front face, the plate carrying a plurality of rows of indicia across a central portion thereof, each row of indicia adapted to be located and a portion thereof to be visible through a corresponding window.  Two rows of indicia carry respectively calibrations representing a range of skinfold measurement values and a range of percent body fat values.  These two rows of indicia and indicia markers associated with corresponding windows are arranged so that at any particular position of the plate in the housing the percentage body fat value is indicated through the one window for the skinfold measurement value indicated through the the other.  Another row of indicia has calibrations representing a range of body weight values, these indicia being positioned and coordinated with a scale of percentage body fat indicia along the edge of the corresponding window so that positioning of the plate to align a value of percent body fat with a specific body weight value will give a visual indication of the ideal weight for that particular value of body weight and value of percentage body fat.

Abstract: "HEAT EXCHANGER CORE FOR RECUPERATOR"               ABSTRACT OF THE DISCLOSURE         The invention relates to a recuperator having an improved core within the primary heat transfer surface. This core,by its unique construction,achieves a combination of reradiative and convective heat transfer which outperforms either of these separate modes while maintaining a low pressure loss.  The core consists of a series of radial plates between which are a series of triangular baffles arranged at an angle with the horizontal of 45 to 70 degrees.  The baffles intercept the flow of flue gas and gently channel the flow of gas into a swirling pattern, thereby enhancing convective heat transfer while main-taining low pressure loss.  The staggered triangular baffles also tend to reflect radiation that would other-wise be lost back to the primary heat transfer surface.

Abstract: ABSTRACT OF THE DISCLOSURE        A self-closing closure for a tube or package having a resilient wall for dispensing flowable material upon the application of pressure on the tube, utilizing a relatively stiff disc for supporting an outwardly extending centrally disposed valve stem having a closed outer surface and a diaphragm member having its periphery interconnected with the periphery of the disc to form a closure unit and its inner portion forming a valve with the valve stem.  The diaphragm member is formed with a relatively thick flange substantially parallel with the walls of the tube for interconnection therewith, a relatively thin, resilient planar portion extending inwardly toward the stem, and a substantially tubular portion surrounding the stem and terminating in an open lip which makes a close, sliding fit with the outer surface of the stem.           The resilient, planar portion of the diaphragm member is normally concave, being formed with an unstressed negative angle of substantially 5° to 15° with a plane perpendicular to the longitudinal axis of the tube.  When assembled with the disc, the stem interacts with the lip of the tubular portion of the diaphragm member to reduce the negative angle by about 2° and to form a secure closure in the rest position of the planar portion.  When pressure on the tube above a predetermined value is applied, the planar portion of the diaphragm member is forced outwardly by the contents of the tube to a convex shape having a positive angle not to exceed 8°, carrying the lip of the tubular portion away from the stem and opening the valve.  Upon release of the pressure on the tube, the planar portion of the diaphragm member automatically returns to its rest position having a concave configuration with respect to the flange and the tube and securely closing the tube.

Abstract: ABSTRACT             Apparatus for supplying a refrigeration system with a low-temperature liquid cryogen, such as carbon dioxide. High pressure liquid cryogen is supplied to a holding chamber where the pressure is reduced to create vapor and solid cryogen forming a low-temperature coolant reservoir.  Vapor is removed from the chamber to maintain the pressure therein at or below the triple point by a compressor and condensed and recovered. The stored cooling power of the reservoir is then employed to meet refrigeration demand and is thereafter replenished over a period of hours.  The storage principle can be incorporated into a variety of different systems.  For example, additional liquid cryogen, particularly CO2 may be supplied from a separate storage vessel to a refrigeration system wherein vapor is created that is transferred to the holding chamber for condensation by melting the solid cryogen.

Abstract: PROCESS FOR HYDROGEN SULFIDE PRODUCTION            Abstract of the Invention A hydrocarbon is partially oxidized in the presence of steam and oxygen in a high temperature reducing flame zone to which sulfur is added in excess of the quantity of hydrogen and carbon monoxide formed to generate a second flame zone.  The gas stream is rapidly cooled to prevent further reactions, then further cooled to condense sulfur to the extent of providing unreacted hydrogen and carbon monoxide in a molar excess over the residual sulfur present in the gas stream.  The resultant gas stream is passed to a catalytic conversion zone where residual sulfur and carbonyl sulfide are converted to hydrogen sulfide.  A formed gas stream free of sulfur and sulfur dioxide may be cooled to below the dew point of water to remove water prior to use.

Abstract: HYDRODESULFURIZATION PROCESS EMPLOYING A PROMOTED CATALYST     Abstract of the  Disclosure An asphaltene-containing oil hydrodesulfurization process employing an upstream catalyst and a downstream catalyst in series. The downstream catalyst comprises supported Group VI and Group VIII metals together with a promoting amount of Group IV-B metal in the form of particles whose surface is shaped by multiple elongated alternating grooves and protrusions.  The upstream catalyst comprises Group VI and Group VIII metals without promotion with Group IV-B metal in the form of particles which may or may not be similarly shaped.  Beds of the downstream and upstream catalyst may be dis-posed in the same or in different reactors.  The adaptation of the grooved particle configuration to the promoted catalyst composition provided the early development of a plateau-like aging curve which was not achieved by the adaptation of the grooved shape to a non-promoted catalyst.
