Abstract: A process for the alkylation of an aromatic hydrocarbon which comprises contacting the aromatic hydrocarbon with a C.sub.2 to C.sub.4 olefin alkylating agent under at least partial liquid phase conditions, and in the presence of a catalyst comprising zeolite SSZ-25. The invention also provides a process for producing a reduced benzene content gasoline blend stock. A benzene-containing light hydrocarbon stream having less than 50 weight present benzene is contacted with a C.sub.2 -C.sub.4 olefin stream in an alkylation zone containing an SSZ-25 catalyst under alkylation conditions to produce an alkylated light hydrocarbon stream with reduced benzene content. The alkylated light hydrocarbon stream is then usable as gasoline blend stock.

Abstract: Color change devices which are capable of undergoing a color change on bending. The devices comprise a flexible substrate having a color generating metal (e.g. a valve metal such as Ta or Nb) at at least one surface and an intimately contacting optically thin anodic film covering the color generating metal and generating a visible color by light interference and absorption effects. The thin anodic film is produced by anodizing the color generating metal in the presence of an adhesion-reducing agent (e.g. a fluoride) for weakening the normally tenacious bond between the anodic film and the metal. Devices of this kind capable of being activated by bending, as well as by separation of the constituent layers, are produced by carrying out the anodization step in the presence of a particular concentration of the adhesion reducing agent from a narrow range (e.g. 40-350 ppm of fluoride).

Abstract: A process for the alkylation or transalkylation of an aromatic hydrocarbon which comprises contacting the aromatic hydrocarbon with a C.sub.2 to C.sub.4 olefin alkylating agent or a polyalkyl aromatic hydrocarbon transalkylating agent, under at least partial liquid phase conditions, and in the presence of a catalyst comprising zeolite beta.

Abstract: Apparatus and procedure for applying a paint or like coating to an elongated strip article using a coating head having an open-sided slot to which coating material is supplied under pressure, and a support such as a roll around which the strip is advanced past the head for receiving from the slot a layer of paint metered between the head and the strip, wherein a load is continuously exerted on the head during operation for urging the head against the applied paint layer on the strip so as to maintain a uniform metering gap between the head and the coated strip surface. The load may be exerted by devices such as air cylinders acting on the head and capable of adjustment to vary the magnitude of the load for different coating operations.

Abstract: Acrylonitrile is produced by passing a gaseous mixture comprising propylene, molecular oxygen and ammonia upwardly through a fluidized bed comprising particles of a highly-active acrylonitrile catalyst in physical admixture with particles of a composite consisting essentially of antimony oxide and silica. The use of the antimony oxide-silica composite moderates the effect of the highly-active acrylonitrile catalyst reducing its activity sufficiently to enable the use of longer residence times, but without reducing the acrylonitrile selectivity of the catalyst.

Abstract: A continuous length of aluminum is anodized during passage through an anodizing electrolyte and then colored during passage through an inorganic coloring electrolyte, in which a counterelectrode is immersed. In the electrolytic coloring stage alternating current with a superimposed D.C. compound is preferably passed between the anodized aluminum and the counterelectrode when the electrolyte is appropriate for such treatment. The alternating current circuit for the electrolytic coloring stage is preferably completed via an electrode immersed in the anodizing electrolyte at a position facing substantially unanodized aluminum so as to effect a liquid contact.
