Abstract: An improved light-sensitive negative-working diazo type film is described. The film includes a diazo-oxide sensitizer and an additive therefore which improves the actinic opacity of the image formed during the diazo process. The additive operates by reacting with the azo dye formed in the image areas. An example of such an additive is a sulfonic acid halide.

Abstract: Hydrogenation catalyst and a process for producing gamma-butyrolactone by hydrogenating a feed compound -- selected from the group consisting of maleic acid, succinic acid, maleic anhydride, succinic anhydride, and mixtures of any of the foregoing -- in the vapor phase, in the presence of said catalyst, which is a highly selective elemental Cu-Pd or Cu-Pt catalyst, in order to produce high yields of gamma-butyrolactone and minimize the formation of by-products.

Abstract: A film web handling mechanism includes a motor for driving the mechanism, and an endless belt for transferring the motor drive to a supply pulley, a take-up pulley and a shuttle-shuttle drive pulley. The supply pulley and the take-up pulley are connected, through a supply clutch and a take-up clutch, to a supply spindle and a take-up spindle. The endless belt is driven in one direction only by the motor, however, the supply and take-up spindles are capable of moving the film web in both a forward and reverse direction. The forward and reverse direction capability of the supply and take-up spindles is accomplished by varying the amount of motor drive transferred to the spindles through the clutches. By means of a single control knob linked to the supply clutch and to the take-up clutch, an operator is able to select a mode of operation.

Abstract: A solventless, fast-setting anaerobic adhesive composition comprises two monomer parts which are adapted to be copolymerized anaerobically at ambient temperature between opposing surfaces to form a high-strength bond thereto. One part comprises a multifunctional acrylate monomer and the other an N-vinylamide monomer. The formulation also includes a redox system consisting of oxidizing and reducing agent components for initiating polymerization between said monomers. The oxidizing agent of the redox system may be present in either one of said parts, preferably with the multifunctional acrylate. The reducing agent is present in the other part, usually the N-vinylamide. Upon anaerobic admixing of the resective parts of the composition at ambient temperature, the oxidizing and reducing agents react to generate free radicals which initiates copolymerization of the monomers to form the desired high-strength adhesive bond to said surfaces.

Abstract: A siding panel and siding panel assembly. Each panel has a pair of ridges near the top edge so that the top edge of the panel can be nailed to a substrate while remaining spaced therefrom. The bottom edge of each panel is provided with a flange terminating in an inverted U-shaped opening adapted to engage the upper edge of an adjacent panel.

Abstract: This invention relates to a product of manufacture comprising a stabilized composition of between about 0.05 and about 15 weight percent of a normally liquid, branched chain dodecyl isomeric mixture of dodecyl-hydroxyphenyl benzotriazole in combination with a heat or light sensitive material, such as a cosmetic preparation, a sunscreening lotion, a polymeric material, a paint, varnish, pigment or dye; and to the method of producing said product.

Abstract: In accordance with the present invention, there is provided herein a cyclic, two-stage process for dinitrating 4-chlorobenzotrifluoride to form 4-chloro-3,5-dinitrobenzotrifluoride in high yield. The process commences with a mononitration stage wherein 4-chlorobenzotrifluoride is substantially completely converted to 4-chloro-3-nitrobenzotrifluoride (the "monoitro" compound) in the presence of a nitric acid, sulfur trioxide and sulfuric acid mixture. The used acid mixture then is diluted with water to form an aqueous used acid layer in which the solubility of the mononitro compound is negligible and a mononitro layer. The aqueous used acid layer then is separated from the mononitro layer and discarded. The mononitro compound thereafter is further nitrated in a dinitration stage in the presence of a fresh nitric acid, sulfur trioxide and sulfuric acid mixture.

Abstract: The invention is directed to a combined display and shipping package which has two major components, an outer sleeve and an inner shell arranged for telescoping engagement with one another. The outer sleeve covers and provides protection for the inner shell during shipment and is slid back over the inner shell in a telescoping manner to permit visual display of an item to be displayed without the full removal of the protective outer sleeve which may or may not have advertising or display information on it. The inner shell has an inclined base so that when the package is used for display purposes, it maintains an inclined position to project the display item into full view of a prospective customer. To prevent the display package from tipping, the item displayed therein is secured in the package in a manner so that the combined centers of gravity for the item displayed and the display package is located to prevent tipping of the package without the need of additional support.

Abstract: Rigid isocyanurate urethane polymers useful for insulation purposes and characterized by unexpected and significantly superior thermal stability are achieved by incorporation therein of 2,3-dibromo-2-butene-1,4-diol, antimony oxide and hydrated alumina.

Abstract: A positive working, thermally stable photoresist, comprising a light-sensitive orthoquinone diazide or naphthoquinone diazide and a polyamic acid condensation product of an aromatic dianhydride and an aromatic di-primary amine, and a support carrying a layer of said photoresist. After exposure, the image is developed in the layer with an alkaline aqueous developer and is unaffected by heating to 500.degree. C, thus allowing the use of the photoresist layer for plasma and sputter-etching as well as ion implantation.

Abstract: Metal algicides, such as zinc and copper, are sprayed in the form of droplets of molten metal onto the surface of roofing granules or onto the surface of asphalt roofing compositions in which said granules are embedded. The metal algicides solidify and adhere on the surface of said granules or compositions as relatively fine, randomly distributed, irregular shaped metal globules. During periods of rain or dew upon atmospheric exposure of roofing compositions thus flame treated, or incorporating therein roofing granules so treated, the oxidized globules become ionized so that metallic algicidal ions are slowly released therefrom and leached over the roofing surface, thus retarding the biological growth of algae and/or fungi over extended periods of time.
