Partially alloyed galvanize product and method

Abstract: A partially alloyed galvanized ferrous strand and a method for its production. The method is characterized by the steps of immersing a clean and oxide-free ferrous strand in a molten zinc galvanizing bath to produce on the strand a coating weight of between 0.2 and 0.5 oz. per square foot. After immersion, the zinc-coated ferrous strand is heat treated and cooled to produce a galvanized coating on said ferrous strand, which coating has a duplex structure characterized by an iron-zinc intermetallic layer consisting essentially of the zeta phase, an overlay of free zinc, and an average iron content between about 2 and less than 4% by weight.

Method and system for dimensional and weight measurements of articles of manufacture by computerized tomography

Abstract: Tomographic imaging of an inanimate object in which a fan-shaped beam of radiation is generated and divided into fan ray elements which are directed through a planar section of the object and detected by a set of detectors. Each detector produces a signal representative of the intensity of the radiation of a detected fan ray element and selected coordinates defining a cross-sectional image of the object are determined from the intensity signals of the detectors. The coordinates are stored and displayed on a display device. The detectors include a scintillation crystal which is provided with a half-solid cylinder of lead disposed on a side of the crystal.

Al and or coal derivatives method for simultaneously calcining and desulfurizing agglomerates co

Abstract: AGGLOMERATES OF COAL AND/OR COAL DERIVAITIVES ARE SIMULTANIOUSLY CALCINED AND DESULFURIZED BY EXPOSURE TO HEATED PARTICLES OF A DESULFURIZING AGENT IN A ROTARY KILN. THE AGGLOMERATES AND HEATED PARTICLES OF THE DESULFURIZING AGENT FLOW COUNTERCURRENTLY THROUGH THE KILN. THE AGGLOMERATES ARE CHARGED INTO THE KILN WITHIN A TEMPERTURE RANGE OF BETWEEN ABOUT AMBIENT TEMPERATURE TO ABOUT 850*F. THE AGGLOMERATES ARE DISCHARGED AT A TEMPERATURE ABOVE ABOUT 1400*F. IT IS PREFERRED TO DISCHARGE THE AGGLOMERATES AT A TEMPERATURE ABOVE ABOUT 1950*F. THE AGGLOMERATES ARE HEATED BY HEAT EXCHANGE WITH THE PARTICLES OF THE DESULFURIZING AGENT WHICH ARE CHARGED INTO THE KILN AT A TEMPERATURE ABOVE ABOUT 1400*F. IT IS PREFERRED TO CHARGE THE PARTICLES OF THE DESULFURZING AGENT AT A TEMPERATURE ABOVE ABOUT 1950*F. THE PARTILES OF THE DESULFURZING AGENT CAN BE AT ABOUT 600*F. AND PREFERABLY ABOUT 1100*F. WHEN DISCHARGED, DEPENDENT UPON THE TEMPERATURE OF THE AGGLOMERATES WHEN CHARGED. THE AGGLOMERATES SO PRODUCED HAVE A RELATIVELY MEDIUM OR LOW REACTIVITY TO CARBON DIOXIDE AT ELEVATED TEMPERATURES, GOOD RESISTANCE TO ABRASION AND SUFFICIENT STRENGTH TO RESIST DEGRADATION WHEN TRANSPORTED AND CHARGED INTO A FURNACE.

Abrasive material suitable for manually blast cleaning ferrous metals prior to painting

Abstract: A non-toxic abrasive material used to manually blast clean the surface of ferrous metals prior to painting comprised of generally spherical particles containing 85% iron, the remainder being substantially oxygen and minor amounts of elements usually found in carbon and alloy steels, and having a metallic core containing 30% to 50% of the iron as metallic iron surrounded by a shell containing the remaining 50% to 70% of the iron as iron oxides. The abrasive material is characterized by having a specific gravity of 5 to 6 and a bulk density of 180 pounds per cubic foot (2.88 grams per cubic centimeter). It is preferred to use particles within the size range of -6,+100 mesh for manual blast cleaning purposes, however particles which are -100 mesh size can be used in special applications.
