Abstract: Abstract of the disclosure The invention relates to a plant for enriching uranium by gaseous diffusion.           This plant includes a plurality of vertical isotope separation towers (1) which are crossed by an isotopic mixture of uranium hexafluoride and each of which is bounded by a leaktight metal enclosure (8a-8b).  A load-withstanding structure (10) absorbs at least part of the loads to which each shell is subjected whilst allowing the enclosure to expand freely.  The lower part (1b) of the tower projects into a thermal protection chamber (9).  The upper part (1a) of the tower is reinforced by a concrete covering or bell-like structure which further provides thermal insulation over that part of the tower.           The invention is applicable in particular to plants which include a great number of large-size towers.

Abstract: POLYTETRAFLUORETHYLENE MOLDING POWER      Abstract of the Disclosure Finely divided polytetrafluoroethylene molding powder is disclosed having a remarkable comination of high apparent density and high moldability, the latter being re-flected as a small difference inspecific gravity (.DELTA.SG) of standard moldings molded at high and low preform pressures. For example, moldings powders having an average particle diam-eter(d50) of no greater than 60, a .DELTA.SG5-1 of no greater than 30 and apparent density of at least 600 g/l  are disclosed. These molding powders are obtained from unique process steps involving either the fine powder type of polytetrafluoro-ethylene of the granular type of polytetrafluoroethylene as the starting material.  The fine powder type is compacted to a high degree, followed by partially decompacting the resul-tant compacted fine powder to the molding powder particle size desired.  When the granular type is the starting material, this is comminuted to the molding powder particle size desired, followed by seperating the molding powdrer into hard and soft material fractions, followed by re-grinding teh relatively coarse, hard fraction by itself to an average particle size of at least as samall as the original combined fractions. The resuslant molding powder is useful in the manner of previous polytetrafluoethylene molding powders with the advantage of requiring reduced mold height andmolding pres-sure toacheive equivalent quality moldings.

Abstract: ABSTRACT OF THE DISCLOSURE           A solid fuel, preferably crude lignite, is comminuted to a particle size of less than 6 millimeters and then gasified togeth-er with the inherent water content thereof at temperatures of up to 1150°C.  The crude gas thus obtained is washed and simultaneous-ly cooled to temperatures below the water dew point.  Subsequently, the crude gas is desulfurized.  According to one embodiment of the invention, the crude gas is next subjected to a carbon dioxide scrub.          The thus-purified gas is then subjected to low-temperature dissoci-ation and a hydrogen-rich gaseous fraction is recovered.  A portion of the hydrogen-rich fraction is combusted in the presence of such a quantity of air that the nitrogen present is sufficient to con-stitute the required proportion of nitrogen in the final ammonia synthesis gas.  The combustion products are cooled to condense the water vapor and the resulting nitrogen-rich gas is then combined with the remainder of the hydrogen-rich fraction to produce a gas which is suitable for the synthesis of ammonia.  According to an-other embodiment of the invention, a first portion of the desulfur-ized crude gas is subjected to the carbon dioxide scrub and the low-temperature dissociation described above so as to yield a hydrogen-rich gaseous fraction.  A second portion of the desulfur-ized gas is combusted in the presence of such a quantity of air that the nitrogen present is sufficient to constitute the required proportion of nitrogen in the final ammonia synthesis gas.  The combustion products are then cooled as above and the resulting nitrogen-rich gas is combined with the hydrogen-rich fraction de-rived from the first portion of the crude gas to produce a gas which is suitable for the synthesis of ammonia.

Abstract: METHOD AND APPARATUS FOR RECORDING INFORMATION ON A    RECORDING SURFACE BY THE USE OF MAGNETIC INK                   Abstract of the Disclosure A silicon body has an array of nozzles therein and a separate magnet for each nozzle integral with the body.  The magnet is disposed adjacent the nozzle with which it cooperates so that it can apply a deflection, prior to break-up of the stream exiting from the nozzle into droplets, to selected portions of the stream.  The droplets, which are formed from the selected portions having the magnetic deflection applied thereto from the magnet cooperating with the nozzle, deflect to a gutter and are not applied to a recording surface, which moves orthogonal to the nozzles.  If desired, the winding of the magnet can have a second excitation frequency supplied thereto to break up the stream into droplets.  The break-up of the stream into droplets also can be accomplished by vibrations produced by a piezoelectric transducer, for example.
