Abstract: ABSTRACT OF THE DISCLOSURE:           A process for the distillation of a readily polymerizable vinyl aromatic compound.  The process of the invention comprises subjecting the compound to distillation in a distillation zone containing from about 50 to about 100 distillation stages, at a reboiler temperature of from about 150°F to about 300°F and a reboiler pressure of from about 30 mm. to about 400 mm. Hg., and in the presence of a-polymerization inhibitor selected from the group consisting of NO, NO2, N2O3, NOCl and the adduct of NO(gas) and styrene, the inhibitor being present in an amount of from about 20 ppm to about 3000 ppm.  The process results in higher recovery of a high purity unsaturated vinyl aromatic compound and concomitantly in the production of less undesirable by-products.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for excluding a noncon-densible gas from voids in a particulate product and thereafter filling the degassed product into a container. If the product includes only entrapped voids, a liquid is directed upwardly through the product in a degassing chamber to purge noncondensible gases from the voids. The upper end of the chamber is then closed at a point below the liquid level and the lower end of the chamber is opened to discharge the degassed product and liquid into a separating mechanism which causes the product to gravitate into the container and the liquid to be collected in a sump for recirculation.           If the product is a low free liquid porous food product that includes both entrapped and occluded voids, the degassing chamber is first closed and vacuumized.  The liquid is then directed upwardly through the product in the degassing chamber while vacuumization continues. The degassing chamber subsequently returns to atmospheric pressure at which time liquid enters the occluded voids and substantially all noncondensible gas is withdrawn from the degassing chamber.  The lower end of the chamber is then opened to discharge the degassed product and liquid as above described.  The resulting filled and sealed container comprises an article of manufacture in the nature of a sealed container with the noncondensible gas removed from the occluded voids being replaced by a liquid.                            -1a-

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a circuit for determining the arrival time of an ultrasonic signal.  The circuit includes a differentiator for transforming an ultrasonic signal to a substantially linearly increasing signal, and a threshold value detector for transforming the linearly increasing signal to an arrival delay signal.  A phase detector in the form of a D-type flip-flop determines the phase position of the arrival delay signal relative to a reference signal.  The phase detector generates early signals on early arrival of the delay signal and late signals on late arrival of the delay signal.  A regu-lator integrator is provided between the phase detector and the differentiator for producing an output voltage for altering the delay period of the arrival delay signal responsive to the phase position of the delay signal.  Resetting apparatus is provided between the regulator integrator and the phase detector for resetting the integrator when the output voltage reaches a pre-determined maximum or minimum value to cause the output voltage to return to zero.  The resetting apparatus includes hysteresis for maintaining resetting signals until the ouput voltage is substantially zero.

Abstract: METHOD OF TREATING FORMATION TO REMOVE AMMONIUM IONS WITHOUT DECREASING PERMEABILITY             Abstract of the Disclosure A method of treating a subterranean formation which has undergone an in situ leaching operation which utilized an ammonium carbonate and/or bicarbonate lixiviant.  In such a leach operation, ammonium ions will absorb into the clay in the formation and will present a threat of contamination to any ground waters that may be present in the formation.  The present method involves flushing the formation with a strong, alkaline solution, e.g., sodium or calcium hydroxide, to convert the ammonium ions to ammonia which is easily carried from the formation by the alkaline solution.  The alkaline solution is modified by adding a monovalent metal salt, e.g., sodium chloride, which prevents the clay from swelling which decreases the permeability of the formation.  After substantially all of the ammonium ions are removed, the formation is then flushed with water to remove any alkaline solution which may remain in the formation.
