Abstract: An apparatus for processing exposed photosensitive film sheets. A liquid used to develop the images on an exposed element as it is transported through the apparatus flows from a trough located above the path of transport. The liquid passes through a screen as it is introduced to and as it flows from the trough.

Abstract: Certain filled propylene polymer compositions, especially propylene homopolymers filled with a carbon black (10-50 parts per 100 parts of polymer) and containing about 30-50 parts of intumescent fire-retardant obtained by heating a mixture of a polyol, a phosphorus acid, and melamine have very high ignition resistance and desirable physical properties. When usual inorganic fillers are used, instead of carbon black, good ignition resistance is not obtained. Carbonaceous materials other than carbon blacks, for example, acetylene blacks, graphite, and so-called Austin black reduce or completely counteract the fire-retardant activity of the intumescent fire retardant. Filled propylene polymer compositions of this invention are particularly suitable in applications where the fire hazard is particularly great, for example, in automotive parts under the hood and in electrical applications.

Abstract: An apparatus for detecting temperature variations over selected regions of living tissue is in the form of a low pressure supported pillow structure including a first wall portion of temperature responsive material and a second wall portion of transparent material to permit viewing of the temperature responsive material. The wall portions comprise a fluid chamber including an inflation valve to permit inflating the pillow structure when gaseous fluids are used.The method of using the pillow structure comprises pressing the temperature responsive film into conformity with the tissue, or portion of other object to be scanned, and viewing the temperature response through the clear wall portion.The flexible film is preferably also elastic and carries liquid crystals on its inner surface to give it a temperature responsive characteristic.

Abstract: New bendroflumethiazide formulations in solid form are provided which are characterized by excellent disintegration and dissolution capabilities even after long periods of storage. The new bendroflumethiazide formulations, for example, in the form of tablets, are formed of one or more excipients and a dry granulation containing one or more fillers, such as lactose and starch, and a preformed partial coprecipitate of bendroflumethiazide and a wetting agent therefor, such as polyvinyl pyrrolidone which converts the bendroflumethiazide into a more hydrophilic form.

Abstract: Process for nuclear chlorination of non-phenolic aromatic compounds, said process comprising contacting and reacting a non-phenolic aromatic compound having a net Hammett .sigma. value of about -0.1 to about 2.0 with chlorine monoxide in the presence of at least one-half an equivalent amount, based on the chlorine monoxide, of an acid having a pK.sub.a no greater than that of trichloroacetic acid, provided, however, when the net Hammett .sigma. value is about 0.7 to about 2.0, the acid has a pK.sub.a no greater than that of trifluoroacetic acid.

Abstract: A seal for a pipe coupling such as is used to connect a gas meter to a gas supply line. The seal is made in two portions, which may be connected by a flexible web, and the portions have integral means for locking together around the nut of a coupling. Each portion has an outer shell with internal protrusions formed on the inner surface thereof. The portions are made of pigmented plastic of a type, such as polypropylene, that forms a white blush on the surface when permanently deformed. Hence when an attempt is made to remove the seal by a wrench or the like, the internal protrusions are forced against the nut, forming white blushes on the outer surface opposite the position of the ribs, giving visual evidence of tampering.

Abstract: An indirect gas turbine power plant is provided which includes primary and secondary combustors wherein fuel is burned and heat is conveyed to a turbine working medium which is subsequently passed through the turbine section of a gas turbine. The gas turbine includes both a compressor section and a turbine section. The primary combustor has a first inlet for receiving exhaust air from the turbine section, a second inlet for receiving fuel and an outlet for the discharge of products of combustion. The secondary combustor includes a first inlet for receiving at least a portion of the products of combustion from the primary combustor, a second inlet for receiving a portion of the products of combustion of the secondary combustor, and an outlet for the discharge of the products of combustion of the secondary combustor. An air heat exchanger for conveying heat from the products of combustion to the compressed air is positioned within the secondary combustor.

Abstract: A particulate or fibrous substrate having a coating of a polymeric amine aluminate or zincate prepared by contacting said substrate with said aluminate or zincate or a precursor thereof and exposing the substrate and aluminate, zincate or precursor to a temperature of 50.degree.-350.degree.

Abstract: A sheet of uncured chlorosulfonated polyethylene having from about 0.3-4 mg/sq. cm of an ultraviolet light absorber deposited on a portion of its surface. The treated sheet can be exposed to ultraviolet light, and it retains seamability and can be securely seamed or bonded to another sheet of chlorosulfonated polyethylene by conventional procedures.

Abstract: There is disclosed an improved process for oxidizing cyclohexane to produce a reaction mixture containing cyclohexyl hydroperoxide and decomposing the cyclohexyl hydroperoxide to form a mixture containing cyclohexanone and cyclohexanol comprising using in the oxidation step and/or the decomposition step as a catalyst a transitional metal complex of certain 1,3-bis(pyridylimino)isoindolines.

Abstract: An electric immersion heater of planar construction for use in industrial processes is constructed of a non-corrodable material and may be immersed at the side of a processing not containing corrosive liquids. The heater includes a thin planar polymeric support frame having side members with end sections extending beyond the end portions of the frame. An electrical resistance heating element wire shrouded with an integral layer of polymeric material is wound around the end portions of the frame to form a substantially flat heating element assembly. Imperforate polymeric cover plates are secured in spaced relationship to opposite faces of the heating element assembly by spacing and securing means engaging the side members of the frame. The peripheral edges of the cover plates are spaced apart to form a gap allowing for free flow of fluid through the heater between the plates throughout the entire extent of the heater.
