Aperture vessel for fluid-suspension particle analyzer

Abstract: Improved aperture vessel is provided for processing a sample of fluid-suspended particles through an aperture during the study of particle characteristics such as size distribution. Vessel may be used with commercially available particle analyzers such as the Coulter electronic, electro-optical and similar types of particle analyzing apparatus. Vessel construction permits a large fraction of sample suspension to be drawn from a sample beaker, through a particle aperture and an aperture chamber, and then into a calibrated volume-measuring bulb. The aperture chamber has an open bottom which, together with a series of associated valves, enables full recovery of the sample suspension fluid as well as both suspended and unsuspended particles after passing through the aperture. This aloquot is recovered in a transfer flask and recycled into the sample beaker. Since the study procedure is quantitative, unlimited numbers of data points are now obtainable on each sample. Greatly improved counting statistics are obtained on samples that contain very few particles of a given size.

Apparatus for hot sawing

Abstract: My invention relates to apparatus for automatically severing tubular or rod-like metal objects in motion, and is more particularly adapted for the rapid cutting of semi-finished pipes and tubes in a continuous butt-weld pipe mill. Pipe mills of this type use large oils of skelp, which as they...

Process for preparing 2-hydroxyethyliminodiacetonitrile

Abstract: 2-Hydroxyethyliminodiacetonitrile is prepared from monoethanolamine, formaldehyde and hydrogen cyanide at pH 7-9. Hydrolysis of the nitrile in an aqueous solution, after removal of any excess cyanide and formaldehyde, results in the formation of 2-hydroxyethyliminodiacetic acid, or corresponding salt, free from contamination. 2-hydroxyethyliminodiacetates are useful as detergent builders.

A Practical Solution to a Cargo Loading Problem at Bethlehem Steel

Abstract: The optimum assignment of structural steel shapes to rail cars is an important logistical problem in the steel industry. In this paper, we discuss an application at Bethlehem Steel that not only involves weight and dimensional constraints, but also customer unloading constraints. The formulation is a generalized bin packing problem which is solved by modifying and extending the first fit decreasing algorithm. The solution algorithm, SOLID (for Structural Optimal Loading IDentification), has been used extensively for one of Bethlehem's high tonnage customers providing very good practical (implementable) results that achieve the desired goals. Bethlehem has enhanced this approach for use with other customers.

Coated ferrous substrate

Abstract: A steel sheet has a composite coating thereon comprising a layer of chromium 5 to 100 microinches thick contiguous to the steel and a layer of aluminum 100 to 1,500 microinches thick contiguous to the layer of chromium. The chromium is deposited on the sheet while the steel is at a temperature within the range of 1,200* to 1,700* F.
