    摘要： 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). The devices can be used as tamper evident labels and the like which show evidence of removal of the labels from articles to which they were originally attached as an indication of tampering.

    摘要： 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.

    摘要： A process and apparatus for coating a surface of an elongated strip article, e.g. aluminum sheet, with a layer of solid polymer material. The process involves heating the polymer to produce a melt having a viscosity of at least 1000 centipoise when measured according to ASTM D4449 at 1 radian per second, extruding the melt onto a moving surface of the strip article through an elongated slot in a coating head having an extended surface adjacent to the slot arranged at an angle to the moving surface to form a coating gap converging in the direction of movement, thereby forming a coating on the strip article, and pushing the coating head towards the surface of the strip article as the melt is extruded as the coating onto the surface from the slot to reduce the coating thickness to a desired range by pressing the extended surface of the coating head onto the coating as the coating is formed. The apparatus includes coating heat, provided with a heater to maintain the viscosity of the melt, and load application device for the coating head, as well as equipment for melting the polymer and supplying the melt under pressure and at the desired temperature to the coating head. The process and apparatus allows strip articles to be coated with thin (1-100 microns) coatings of polymer materials without employing liquids as solvents or the like that cause atmospheric pollution problems.

    摘要： Maleic anhydride is produced by passing a C.sub.4 to C.sub.12 hydrocarbon stream together with molecular oxygen over a fixed bed containing a vanadium molybdate catalyst promoted with a novel cobalt tantalate having the formulaCoTa.sub.b O.sub.xwherein b is a number from about 1.0 to about 4.0 and x is a number from about 3.5 to about 11.0. The catalyst is prepared by calcining a slurry containing cobalt oxide and tantalum oxide, or their precursors, in at a temperature range from about 525.degree. to about 1200.degree. C. for about 1 to about 40 hours to obtain a cobalt tantalate, which is then slurried with a mixture of oxides of vanadium and molybdenum, or their precursors, dried, and then calcined at a temperature from about 300.degree. to about 650.degree. C. for about 0.5 to about 24 hours. A support can be used for the catalyst.
