Patent number: 4842040Abstract: Metal strip 9 cast directly from the melt onto a cylindrical casting drum 20 is made more uniform in thickness and in structure by making the temperature of the casting surface more uniform. This is accomplished by a novel arrangement of coolant channels 25 beneath the casting surface 10. The channels generally run circumferentially around the casting surface 10, parallel to and spaced from adjacent channels. At least one coolant inlet 21 and one coolant outlet 22 supply and withdraw coolant to each channel. Inlets (21a, 21b) and outlets (22a and 22b) of adjacent channels are staggered circumferentially from the inlets and outlets of the adjacent channels so that the cooler regions around inlets are staggered to balance the temperature across and around the surface.Type: GrantFiled: August 10, 1988Date of Patent: June 27, 1989Assignee: Battelle Development CorporationInventors: James R. Bibler, Richard A. Gleixner

Patent number: 4842042Abstract: A smooth roll skimmer 36 may be used in the casting of strip 34 by the melt drag process to provide gauge control and a smooth upper surface. Liquid melt 32 is cast on the moving chilled substrate 33 where it solidifies to a strip. The skimmer 36 is positioned above the substrate 33 and at a fixed gap therefrom by convenient means, e.g., by a rolling spacer 37 between the casting surface and the roll skimmer. The roll skimmer is not chilled and is not used to solidify the liquid. It meters and smooths the liquid prior to solidification on the substrate. A parting agent may be used on the roll skimmer to prevent sticking and to reduce heat transfer. A carbonaceous soot from a partially combusted hydrocarbon fuel is a useful parting agent.Type: GrantFiled: March 7, 1988Date of Patent: June 27, 1989Assignee: Battelle Development CorporationInventors: Edwin S.

Patent number: 4752314Abstract: A glass melting system involving preheating, precalcining, and prefluxing of batch materials prior to injection into a glass furnace. The precursors are heated by convection rather than by radiation in present furnaces. Upon injection into the furnace, batch materials are intimately coated with molten flux so as to undergo or at least begin the process of dissolution reaction prior to entering the melt pool.Type: GrantFiled: July 6, 1987Date of Patent: June 21, 1988Assignee: Battelle Development CorporationInventors: Alexander G. Fassbender, Paul C. Walkup, Lyle K. Mudge
-
Patent number: 4749024Abstract: Metal strip 3 may be cast directly from molten metal in an open tundish 2 onto a chill roll 1. Strip thickness is controlled by contouring the tundish lip 14 with an offset 10 near the casting wheel. This can be used remedially to offset the natural tendency for the strip to be thicker near the edges, which is undesirable for cold rolling, or it may be used creatively to produce contoured strip.Type: GrantFiled: September 28, 1987Date of Patent: June 7, 1988Assignee: Battelle Development CorporationInventors: Edwin S. Bartlett, Richard A. Wood

Patent number: 4704084Abstract: Nitrogen oxide pollutants are substantially reduced and sulfur dioxide minimized in multisolid fluidized beds by staged combustion of the fuel. The lower combustion region is operated at substoichiometric conditions such that NO.sub.x is reduced by carbon and carbon monoxide to nitrogen gas. The upper combustion region is operated at excess oxygen conditions to complete the combustion of char and carbon monoxide. Elevated temperature excursions in the upper region which deter sulfur capture are prevented by recycling cool entrained bed particles therethrough.Type: GrantFiled: December 26, 1979Date of Patent: November 3, 1987Assignee: Battelle Development CorporationInventors: Ke-tien Liu, Herman Nack

Patent number: 4618764Abstract: An optical fiber disposed between a light source and a photodetector is subjected at a number of points, equispaced along its axis, to a transverse pressure causing a significant attenuation of the transmitted luminous radiation. The optimum spacing of the pressure points is a function of the radius of the fiber core and of the refractive indices of its core and its envelope. These pressure points are formed by turns of a substantially incompressible helix which is wound around the fiber and which may be constituted by an internal or external rib of a surrounding flexible sheath of similarly incompressible material. The pressure may be applied by a piezoelectrical transducer and may be modulated by an electrical signal to be picked up by the photodetector.Type: GrantFiled: November 14, 1985Date of Patent: October 21, 1986Assignee: Battelle Development CorporationInventor: Alan L. Harmer

Patent number: 4614222Abstract: Apparatus and method for continuous casting of amorphous or polycrystalline metal strip from a melt. The molten metal is delivered from a reservoir (2) to a moving chill surface, preferably a cylindrical roll (1) through an orifice (3) in the reservoir (2). The gap between the reservoir (2) and the chill surface (1) is not fixed as in prior methods but is variable due to a resilient bias on the reservoir toward the chill surface. A pivot (10) and counterweight (11) are convenient apparatus for resiliently biasing the reservoir. The small portion of the reservoir (2) therefore rides lightly upon the molten metal film delivered to the chill surface or upon the solidified metal strip. The variable gap allows better control over the process and better quality surfaces on the metal strip.Type: GrantFiled: May 16, 1984Date of Patent: September 30, 1986Assignee: Battelle Development CorporationInventor: Robert E. Maringer

Patent number: 4462234Abstract: High-strength aluminum alloys and other hot-short-sensitive alloys can be extruded at rapid rates through a cooled, double reduction die (3) without hot-short cracking or scoring caused by die pickup. A primary reduction die (4) has a long, cooled primary land (5) and is followed by a secondary reduction die (6). A metal billet (15) may be extruded through the primary die (4) at about the solidus temperature of its lowest melting phase, then cooled as it passes through the primary die land (5) to reduce or maintain the temperature below the solidus temperature and, finally, the primary extrusion is reduced in cross section in the secondary die (6) by about 2-50%. The temperature, the back pressure caused by the second reduction, and the low friction through the primary land (5) contribute to eliminate hot-short cracks and minimize serious pickup scoring at surprising rates of at least about 18 meters per minute (60 ft/min) for 2024 aluminum rod.Type: GrantFiled: June 1, 1981Date of Patent: July 31, 1984Assignee: Battelle Development CorporationInventors: Robert J. Fiorentino, E. Garland Smith, Jr.
