Abstract: In storage containers for fluids, a disperser/diffuser member is positioned between the inner end of the fillpipe and the interior of the container, to cause dispersion of the fluid flowing into the container from the fillpipe during a filling operation. The disperser member has therein a multiplicity of tortuous fluid passages, and may be used in a subterranean storage container, or in a mobile storage and transportation container (tank truck).
Abstract: A process for vapor phase ammoxidation of hydrocarbons which comprises reacting vapors of ammonia and said hydrocarbon in the presence of a molten salt eutectic mixture of V.sub.2 O.sub.5 and K.sub.2 O, said molten salt being atomized in the presence of said ammonia and hydrocarbon, and, optionally, said spent molten salt being regenerated by air oxidation and recycled for reuse. The invention also embodies an apparatus for the ammoxidation process which comprises a reactor vessel fitted with (a) input means for ammonia and hydrocarbon, (b) an atomizing apparatus within said reactor, (c) means for feeding the molten eutectic salt from an upper reservoir to said atomizing apparatus, (d) a lower reservoir for spent molten salt, and (e) a gas-lift to move said spent salt from said lower reservoir to said upper reservoir.
Abstract: An apparatus for producing ring patterns from electron diffraction spot patterns, which comprises in combination a transparent disc rotatably mounted, rotating means for said disc, a light source beneath said disc, and photographic means above said disc. The invention also embodies a method for producing ring pattern negatives from an electron diffraction spot pattern negative by photographing the spot pattern negative while it revolves at a speed of at least about 0.5 rps.

Abstract: A process for the preparation of a lower alkyl ester of a phthalic acid by contacting an ammonium salt of an aromatic carboxylic acid with vapors of a lower alkanol at a temperature between about 230.degree.C and about 300.degree.C in the presence of an alkaline esterification catalyst.
