    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: 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.

    Abstract: A process is set forth for reacting impure toluene to obtain benzene, toluene and a para-rich xylene stream, which are substantially free of close-boiling non-aromatics. The impure toluene comprises at least 70 wt % toluene and between about 0.2 wt % and about 5 wt % close-boiling non-aromatics. The process may also comprise aromatizing a naphtha over a non-acidic catalyst. The impure toluene from the aromatization step is passed over an acidic intermediate pore zeolite to produce a para-rich xylene stream and chemically pure benzene.

    Abstract: There are herein disclosed an L-type zeolite catalyst which is obtainable by supporting a platinum component, one or more halogen components and one or more metal components selected from the group Ib of the periodic table on an L-type zeolite, the support amount of one or more metal components selected from the group Ib being in the range of 0.001 to 3% by weight based on the total weight of the catalyst in terms of the metal, a molar ratio of one or more metal components selected from the group Ib/platinum being in the range of 0.01 to 1; and a method for producing aromatic hydrocarbons or a gasoline having a high octane number which comprises the step of bringing one or more fractions selected from a C6 fraction, a C7 fraction, and a C8.sup.+ fraction into contact with this catalyst. According to the present invention, there are provided a catalyst containing an L-type zeolite as a carrier which is desirable as a catalyst for the production of aromatic hydrocarbons or a gasoline having a high octane number and which can inhibit a cracking activity and the formation of coke and can improve an aromatic selectivity and a liquid yield.

    Abstract: Apparatus for coating a strip article comprises a coating head having a coating surface and elongated open-sided slot formed in the coating surface communicating with an interior channel for delivery of coating material to said slot for transfer to a strip article to be coated. The slot has a slot extension extending into the coating surface at at least one longitudinal end of the slot for applying coating material to an edge region of the strip article. The slot extension communicates with the interior channel only through a constricted opening that prevents substantial leakage of coating material from the slot extension when the slot extension becomes uncovered by the edge region of the strip article. In this way, the strip article can be coated completely up to its transverse edges, without risk of substantial spillage of coating material if the ends of the coating slot become uncovered by the strip article due to inaccurate tracking or variable strip width.
