Abstract: Method and means for continuously contact-coating one side only of a ferrous base metal strip with a molten coating metal. One or more roll means are provided to conduct the strip surface to be coated above the surface of a bath of the molten coating metal. The strip surface to be coated is caused to travel sufficiently close to the molten coating metal bath surface that the surface tension and wetting characteristics of the coating metal will permit the formation of a meniscus which will continuously contact and coat the strip surface. The coating is subjected to jet finishing. The strip is maintained in a protective non-oxidizing atmosphere at least until the one side thereof is coated. The strip may be maintained in the protective non-oxidizing atmosphere until it is sufficiently cooled to prevent the formation of a visible oxide on the uncoated side thereof.

Abstract: An apparatus is described for continuously dyeing textile fabrics. The apparatus may be best described in terms of its operation as follows: The fabric is preheated in a chamber and then impregnated with a bath consisting of dyestuff dissolved in a solvent in another chamber. Then the fabric is treated in a developing chamber where the dyestuff is fixed thereon by evaporation of the solvent. The excess solvent is then eliminated from the fabric in a water vapor atmosphere. The treatment in the developing chamber is effected by passing the fabric continuously and alternately a plurality of times to and from a zone of saturated solvent vapor and a zone of superheated solvent vapor. The solvent in these two zones is substantially the same as the solvent in the bath.

Abstract: A method of and apparatus for continuously, evenly and uniformly coating one side only of a moving strip of material, such as steel, with molten zinc or other fluid coating material while effectively preventing the coating material from contacting the opposite side of the moving strip.

Abstract: A method and apparatus for use in continuously applying molten coating metal, such as in galvanizing or aluminizing to tubes, rods, wire or other work pieces passing through a metallic bath. The molten metal in a reservoir is discharged onto the tube or rod, the metal flowing around the tube or rod being controlled by a splash tube. The coating metal is progressively agitated and cooled within the splash tube, after which the tubing or rod is accurately centered to exit the splash tube with an even coating of the desired thickness, such coating being in a stable condition. The entire system is enclosed in an inert atmosphere eliminating the formation of "galvanizers' dross", oxides of aluminum, etc.

Abstract: A method and apparatus for controlling the temperatures of inner wall surfaces of a hood and of the atmosphere in the vicinity of the inner wall surfaces in the process of fabricating heat-reflecting glass sheets by means of a traversing spraying means which is located over a transfer line of a hot glass sheet. The hood is provided with means to maintain the temperature of the inner wall surfaces which surround a spraying zone and onto which solution particles from the spraying means are caught or deposited and the temperature of the atmosphere adjoining the inner surface walls at such a suitable level that the metal compound in the solution particles which has been caught on the inner wall surfaces of the hood is vaporized in an undecomposed state and removed together with the gaseous solvent and decomposition gas.

Abstract: A continuous glass ribbon advances from a float forming chamber past a first heat source and into a coating chamber where a surface of the glass ribbon is provided with a pyrolytic oxide coating as a second heat source heats the opposed surface of the glass ribbon. Thereafter the glass ribbon is advanced into an annealing lehr to relieve residual stress in the glass ribbon. The first heat source reduces the heat loss of the ribbon as it advances into the coating chamber to provide a durable pyrolytic oxide coating on the glass ribbon. The second heat source heats the ribbon to minimize or eliminate glass ribbon warpage.
