Abstract: The slab edge forming and insulating system includes edge members and support braces. The edge members include an elongated shell having an upright portion with an insulated inside surface, an upper portion and a lower portion. Each of the upper and lower portions has formed edges. Open cross sectioned support braces having upper and lower formed edges for engaging the formed edges of the elongated shell are fixed to a footing and connected to the edge members. The edge members form and insulate the edges of the poured concrete of the slab while the open cross sectioned support braces receive the poured concrete of the slab and thus anchor the edge members to the edge of the slab.

Abstract: There is disclosed a thermal printer system in which variations in voltage (and the energy corresponding thereto) supplied to resistance elements of a print head are electronically compensated for. The voltage at the print head is monitored as a line of pixels is being printed pixel by pixel. Units of energy (corresponding to the measured voltage) which have been supplied to the resistance elements are counted, the counts are added together pixel by pixel to obtain cumulative totals and the cumulative totals converted into "compensating" numbers. An image data number for each pixel is compared to the corresponding compensating number, and a respective resistance element is pulsed (energized) a requisite number of times until the image data and compensating numbers match thus achieving a desired level of print density corresponding to the respective image data number.

Abstract: In a digital image scanning system, dynamic testing of digital and analog channels is performed by injecting photosite-by-photosite variable test data to simulate imager signals. The test data is stored at photosite related addresses in random access memory means and are accessed by a pixel (photosite) counter for output to the channels under test.

Abstract: A process for controlling zinc vapor in a finishing process for a hot dip zinc based coating on a ferrous base metal strip in which the strip emerges from the coating bath into an enclosed chamber, by injecting high dew point gas into the chamber. The process is applicable on both a one side and two side coating process. Preferably the atmosphere has about 1-3% water vapor, by volume, for both one-sided and two-sided process.

Abstract: Improved means and method are provided for the guidance of metallic strip in a horizontal continuous furnace having hearth rolls and wherein the strip temperature and furnace atmosphere are such as to promote the transfer of metal, oxides, dirt and the like from the metallic strip to some at least of the hearth rolls. At least one lifting hearth roll is provided in an elevated position wherein it lifts the metallic strip from those critical hearth rolls subject to contamination transfer. The elevated position of the lifting roll and its diameter are so chosen to assure a wrap-around contact between the metallic strip and the lifting roll in its elevated position. In practice the metallic strip is fed through the furnace and continuous operation is begun. The lifting roll, in its elevated position, maintains the metallic strip out of contact with the critical hearth rolls.

An improved nozzle of high efficiency is disclosed having an elongated plenum chamber communicating directly with a pair of elongated converging lips defining an orifice of about 0.03 to about 0.20 inch, the interior surface of the plenum chamber merging smoothly into each lip with a radius of curvature substantially equal to the orifice opening. The near-field region of the nozzle is about 8-10 times the orifice opening.

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. Alternatively, at least that side of the strip to be coated with the molten coating metal is coated with a flux which remains on the strip until contacted by the coating metal meniscus.

Abstract: A method of preparing carbon steel strip and sheet for hot dip metallic coating in a Selas-type direct-fired furnace, wherein the atmosphere in the furnace is controlled to contain from about 3% oxygen to about 2% excess combustibles by volume, thereby forming a thin iron oxide film on the carbon steel surfaces. The strip and sheet is then heated in a subsequent furnace containing at least 5% hydrogen by volume at a temperature sufficient to reduce the oxide film, viz., at least about 675.degree. C. The direct-fired furnace is preferably operated at stoichiometrically equivalent fuel:air ratios.
