Abstract: An improved method and apparatus for separating and recovering zinc and zinc alloy particles which are nickel plated from non-ferrous non-magnetic automotive scrap material. The scrap material is transported on a belt conveyor past a magnetic field where the path of the zinc particles with nickel are deflected into a path separated from the remaining scrap material. Subsequently the zinc and zinc alloy materials are recovered by a pyrometallurgical process.

Abstract: Apparatus for using radiant energy to cure inked or coated objects such as containers in which the objects are rotated and revolved at least part of the way around a linear energy source. A reflector is provided which focuses the energy on the surface of the rotating object and tracks it in its revolution around the energy source.

Abstract: Wells and like borings into the earth's surface, especially those for the production of petroleum and gas, are very well and efficaciously cemented with cement compositions or pastes containing, as their effective gel control and cement set retardation agent, an additive that is a resulfonated, alkaline oxidized, hydrolyzed, partially desulfonated lignosulfonate product.

Abstract: This invention relates to lignosulfonate derivatives and alkali metal salts thereof derived from sulfite waste liquor that has been subjected to alkaline oxidation, hydrolysis and partial desulfonation with subsequent resulfonation; and followed by one or more addition and double decomposition and reactions thereof; as well as the method of cementing subterranean geological formations penetrated by well bores utilizing these additives in well cementing compositions.

Abstract: Methods by which a dry-formed loose fibrous web is bonded by applying to one of its surfaces a low add-on level of a relatively high binder solids concentration bonding material to form a once-bonded web, and to the other side of the web, a greater add-on level of a relatively lower solids concentration bonding material, the first-applied emulsion preferably adding from about 20% to about 40% binder solids by weight, and the second-applied adding the rest of the total binder solids to be included in the fibrous web product. The bonding material can be a solution or emulsion. Preferably, the first and second-applied bonding materials are water-based latex emulsions, the solids concentration of the first-applied emulsion is from about 15% to about 25% by weight, that of the second-applied emulsion is from about 10% to about 20% by weight based on the total binder solids to be included in the fibrous web product, and a vacuum draws the second-applied bonding material into the web.

Abstract: A carrier for one or more stackable articles formed from a paperboard blank of generally rectangular configuration. The blank is folded about a score line intermediate its short ends so that adjacent regions are divergent at an angle. A pair of aligned slots in each adjacent region serve as a hand-hold. The blank further has confronting side panels extending downwardly from the adjacent, divergent regions, and panel portions cut from the side panels are folded toward one another along score lines adjacent free ends of the blank in formation of openings in the side panels, and are fastened to one another in provision of a bottom for the carrier. An article may be carried singly, or several stacked upon one another while supported on the bottom and projecting through, and retained within blank portions that define, the side-panel openings.

Abstract: Photopolymerizable epoxide compositions are provided which contain photoinitiators decomposable upon exposure to electromagnetic radiation to produce a Lewis acid and polymerizable epoxide compounds including an epoxide ether compound having the following general structural formula: ##STR1## wherein n equals 1-3 and wherein R is an aliphatic or cycloaliphatic group having 5-12 carbon atoms. Other epoxide compounds may be used in combination therewith to provide compositions which cure rapidly to a tack-free condition at ambient temperatures. Specific epoxide ethers disclosed are those in which n=1 and R is a group selected from the class of 2,2-dimethylpropane, 2-ethyl-1,3-hexane, 1,4-dimethylcyclohexane and 1,10-decane.

Abstract: A company container a sidewall portion of generally circular cross-sectional configuration extending from a closed end portion to an open end portion. The container is of molded expanded polystyrene having a density of from about 1.0 to about 15 lbs./ft.sup.3, and a thickness of from about 35 to about 100 mils. A reinforcing band encircling the sidewall portion and firmly adherent thereto comprises paper of from about 1 to about 2 mils thick, and having a basis weight of from about 9 to about 20 lbs./ream.

Abstract: A carton blank may be folded by folder blades supported on an adjustable plate positioned on one side of a chain which carries a clamp by which the carton blank is pulled through the machine. After folding, the blank is glued to complete a flat shell and the shell is then inverted; the clamp is articulated so the shell may be turned in a horizontal plane to align a datum line on the shell to a datum line on a cartoner machine.

Abstract: Apparatus for dispensing and selectively cutting lengths of plastic film from a roll. A box-shaped container has side, front, rear, and bottom walls, and a cover hinged adjacent the rear wall. The cover affords access to the container, so that a packaged roll of film may be placed inside with its axis extending between and perpendicular to the side walls. The container has side spacers that normally receive a 4-inch width roll package, and a narrower, 2-inch width roll package may be received for which there are provided extensions for the spacers. The spacers slightly compress the package to provide drag on the roll as it becomes lighter. Disposition of the roll package is such that film may be removed from the upper region of the roll, through a slotted opening between the front wall and the adjacent free edge of the closed cover.

Abstract: Apparatus and method for the manufacture of a fibrous web comprises a distributor for depositing dry wood fibers on a planar section of a linearly movable forming wire. A suction box is disposed to the side of the forming wire opposite the distributor. The distributor and suction box are so cooperatively constructed and arranged as to impart a velocity component to the fibers in the direction of movement of the forming wire, so that the angle of inclination of fiber deposition relative to the moving forming wire is from about 21 degrees to about 30 degrees.

Abstract: This invention relates to methods for forming a nonwoven fibrous web on a foraminous forming surface moving at a velocity in excess of about 500 feet per minute. In forming satisfactory uniform webs, the fibers are conveyed to the forming surface in a gaseous stream whereby the relative surface-to-fiber velocity along the moving surface is maintained within a critical ratio relative to the fiber velocity normal to the moving surface.

Abstract: The instant invention relates to an end closure or cover for a metal container comprising a substantially flat sheet metal lid seamed about its extremity to the container body closing the body end. The lid has a pour opening having a closure hingeably connected to the lid and closing the pour opening provided to retain the closure against inward displacement thereby resisting atmospheric pressure and premature opening of the container and against outward displacement due to internal pressure during processing.

Abstract: An apparatus for the high speed transfer of workpieces in a multi-station machine. The stations are located in a common plane, in axial alignment and are equidistantly spaced. The apparatus utilizes a carrier assembly, which incorporates a pair of parallel barrels with a shaft received within the bore of each barrel. A series of confronting openings, which expose the shafts, are formed in the barrel walls at intervals which correspond with the spacing of the machine stations. A pair of gripping fingers are located at each barrel opening. A first finger is affixed to the barrel, extending outwardly therefrom, while a second finger which is affixed to the shaft, extends through the barrel wall opening to cooperate with the first finger. By pivoting the barrels in unison, with respect to the shafts, which are rotatably locked, the fingers can be caused to assume either a gripping or releasing attitude.
