Abstract: A new combination of steel strip electrolytic plating process steps which eliminate iron ion dissolution from continuous-strip steel substrate into chemically-corrosive plating solutions, such as Halogen-bath or methylsulphonic acid plating solutions, of horizontal passline electrolytic tin plating means which plate a single strip surface at a time. The previous use of a cyanide in Halogen-bath tin plating operations which formed a hazardous precipitant (prussian blue) is eliminated by eliminating iron ion dissolution from the steel strip substrate. And conversion of stannous ions to stannic ions, which formed additional Halogen-bath precipitant, is substantially eliminated.

Abstract: The carrying case-wearing vest which is convertible between a carrying case for fishing rods, guns and hunting and fishing accessories and a vest garment configuration includes a unit of material having two mirror image panels (a right and left panel) which may be folded together and releasably connected by a full perimeter zipper to form a carrying case configuration which may support the transportation of a fishing pole or hunting artillery. The upper corner of the front right panel may be fastened by a buckle to the back side of the left lower panel and the upper corner of the left front panel may be fastened by a buckle to the back side of the lower corner of the right panel to form a vest for wearing the carrying case in a vest garment configuration.

Abstract: The invention provides continuously-cast product free of ambient atmosphere contaminants and free of nonmetal solid entrapment. Methods and apparatus are provided for flow of molten metal from ladle to tundish to mold machine, free of contact with ambient atmosphere; and, tundish slag cover is removed, by discharge of a nonreactive gas to provide a selected limited surface area of tundish metal, which is free of slag cover, for insertion of a ladle shroud to deliver molten metal, free of entrapment of nonmetal slag cover, for continuous casting. Transitional casts, before clean metal is obtainable with each new ladle of molten metal, are eliminated; and the duration of uninterrupted continuous casting of clean metal is extended.

Abstract: New composite-coated flat-rolled steel product and new methods of manufacture in which low-carbon steel, as received in cold-reduced continuous strip form is prepared for plating, a corrosion-prevention plating is applied, and a selected polymeric coating with lubricant is applied as the finish surface. The resulting composite-coated steel substrate is cold-rolled to decrease the composite-coated steel substrate gage. Selection of cold rolling steps, with non-use or selected use of stress-relief type of heat treatment before and/or after an initial cold-rolling of the steel substrate as received prior to surface preparation, provides for selective tin mill manufacture of composite-coated steel of various weights per unit area, for example, in the range of about 35 to about 100 lb/bb, produced by cold rolling of the composite-coated flat-rolled steel.

Abstract: Continuous removal of particulate surface contaminants, for example, from flat-rolled steel work product, is achieved free of unscheduled interruption by continuing control of surface cleaning liquid characteristics which enables continuing recycling. A major portion of the cleaning liquid of a large capacity tank is continuously circulated between surface treatment of the work product and a continuous in-line type cyclone filtering apparatus, with continuous return of filtrate to surface cleansing. A minor portion (about ten percent) of the cleaning liquid capacity is used to concentrate contaminants by continuously purging the filtering apparatus. Concentrated contaminants are directed to a non-magnetic tank structure with sources of magnetic flux mounted along its external surface such that penetrating magnetic flux acts internally to separate and retain contaminants. Decontaminated liquid is returned for continuing surface cleansing.

Abstract: Scoreline, profiling and reinforcing features are provided for an easy-access sheet metal end closure (20) and an integral opener (44). An endwall panel (28) is formed so as to substantially eliminate flexing of the sheet metal during rupture of residual metal of scoreline means defining a U-shaped tear strip (30). Such tear strip is oriented with its arcuately-shaped closed end (32) contiguous to the periphery of such endwall panel -with scoreline legs (34, 35) directed toward a portion at its geometric center (26). The opener is fabricated with a chisel-point (92) at its working end (66) to initiate puncture of such arcuate-shaped scoreline by Class I lever action. Rupturing of the scoreline is followed by pivoting of the opener about a pair of fulcrum points, (82, 83) which contact the panel one each external to a, side of opening 62, with movement of the opening about such fulcrum points rupturing the scoreline legs by Class; II lever action.

Abstract: In-line flat-rolled steel cleansing and finishing methods and apparatus are disclosed which enable flat-rolled steel, as supplied with surface areas contaminated with iron fines and other debris from gauge reduction operations, to be continuously processed in-line, free of interruptions for cleansing purposes. Continuous-strip methods and apparatus are disclosed which enable in-line continuous-strip cleansing in a manner which decreases iron fines carried by strip surfaces to a desired level while providing for continuous uniform cleansing. Carry-over of iron fines from the cleansing operations so decreases such that iron content of a coating means is decreased resulting in improved corrosion-protection coating. Diminishing iron content in a hot-dip galvanizing bath increases efficiency of aluminum additions and diminishes iron-aluminum dross.

Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary can packs free of any requirement for applying organic coating or adding organic coating for repair purposes after fabrication and before such direct usage. Cupping of precoated flat-rolled sheet metal can stock using preselected tooling configurations and clearance avoids any increase in side wall metal thickness gage. Tension elongation during redraw is controlled over side wall height by clamping solely between planar clamping surfaces, tooling configurations and preselected clearances to decrease thickness gage uniformly over side wall height between flange metal open end of can body and curved transition zone at closed end.

Abstract: Rigid container structure for hermetic sealing of particulate solids which emit an off-gas during containment. Provisions are made for enclosing chamber space with a gas-permeable imperforate membrane film so as to selectively separate and retain an off-gas out of contact with container contents. In a specific embodiment, carbon dioxide is selectively separated from coffee contents while the entire container, including such enclosed chamber as established, is hermetically sealed from ambient atmosphere. Provision is also made for venting of a separated off-gas in initiating a rupture of an end closure structure prior to full opening of the container. That arrangement further diminishes the opportunity for inadvertent discharge of particulate solids due to expulsion of gas from inert gas purging and from gas emitted during hermetic sealing.

Abstract: Apparatus for use in chime seam joinder of a sheet metal convenience-feature end closure (133) to a sheet metal can body (153) having a non-cylindrical sidewall. Countersunk panel (112) with unitary chuck wall (100) interfit within an open end of the can body. A peripheral scoreline (102) in the countersunk panel, which contiguous to the chuck wall, defines the separable endwall panel. After that separation, substantially no obstruction to removal of solid-pack contents, as a single piece, remains. Seaming chuck tooling (172) provides continuous backing support peripherally along the inner surface of the chuck wall during chime seam joinder. Cutaway shaping (180) of seaming chuck portions 176, 177 eliminates registry concerns as to whether a single longitudinally-rigid integral opener (148), with its working edge (136) contiguous to the panel peripheral scoreline and the chuck wall, is located at either distal end of a centrally located axis (174) of the end closure.

Abstract: A coating control system is provided enabling continuous operations, free of interruption for coating control purposes, while achieving desired coating weight and thickness profile for the various gages, widths and coating specifications encountered on a given continuous strip production line. In each of a pair of elongated pneumatic dies, a pressurized gas jet is controllably shaped and directed by flow-control means internally-mounted of each pneumatic die to impinge against its respective substrate coated surface with its major directional component of force being controlled to be perpendicularly transverse to the travel path of the coated strip across its full width. Adjustment of such internally-mounted means is coordinated with control of gas pressure supply and/or adjustment of die positioning means to maintain desired coating weight and coating profile across the width of the strip.

Abstract: Flat-rolled sheet metal is manufactured to preselected gage, mechanical properties and surface finish and is fabricated into unitary sheet metal shingle structures with interlocking folded over sheet metal layers providing for ease of assembly and weatherproofing along each side of a rectangular configuration portion which remains exposed after assembly of shingle structures in side-by-side interlocked relationship in a horizontal direction, and in overlapping partially-covering relationship in a vertical direction. Galvanized mild steel provides lightweight, high-tensile strength, impact-resistant and long-service-life shingle structure. Finish coating enables selection of coloring and thermosetting polymeric coatings facilitate embossing of exposed portions to simulate the appearance of cedar shakes or other types of shingles.

Abstract: New technology for fabricating a one-piece cup-shaped can body is formed free of side wall ironing from can stock comprising flat-rolled sheet metal substrate precoated with protective organic coating and forming lubricant. A plurality of successive diameter-reduction operations are carried out a planar blank and cup-shaped work product during which side wall height is increased and side wall substrate is decreased in thickness to provide controlled uniformity in side wall substrate thickness over about 85% to about 95% of side wall height for such can body. The fabricating tooling provides for a preselected clearance between a punch peripheral wall and a die cavity internal wall in each of such plurality of diameter-reduction operations to achieve a desired decrease in side wall thickness as the precoated substrate is moved into a die cavity by relative movement of its respective punch.

Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary packs free of any requirement for washing, organic coating or repair of organic coating after fabrication and before such direct usage. Selective organic precoating includes embodying a blooming compound which is made available as draw lubricant responsive to heat and/or pressure of draw forming; also, surface application of a draw lubricant after curing of the organic coating. Combined lubricant on each surface is verified before start of fabricating. Draw-forming of tensile strength sheet metal is controlled over side wall height by clamping solely between planar clamping surfaces and by interruption of draw to establish a flange at the open end of cup-shaped work product.
