Abstract: One assembly part is bonded to another by a patch separated from an adhesive strip by a piercing punch after which the separated patch is applied to the assembly parts in a controlled, conformed manner by a bonding punch which may be coaxial with the piercing punch.

Abstract: An improvement in distributors for air-laid fibers wherein one or more impellers within a distributor housing receive fibers from a hammer mill or other source, and impel fibers smaller than a certain size through a first screen extending over the outlet opening of the distributor housing onto a moving forming wire. A partial vacuum is formed beneath the forming wire to hold the fibers thereon and to form a continuous web of fibrous material. The impellers are blades which rotate about a vertical shaft immediately above the first screen. The invention is directed to improvements in the first screen, wherein it is endless and is mounted for movement across the outlet opening of the distributor housing, in the same direction and at the same speed as the forming wire.

Abstract: An inclined conveyor for lowering uniformly spaced, cylindrical articles comprises a pair of inclined rails, paired pivotal rockers and fingers disposed along the inclined rails, and a pair of drawbars for sequentially pivoting the inclined pairs of rockers and fingers. The paired pivotal rockers and fingers are so cooperably disposed as to define a series of article receiving pockets accommodating controlled gravitational movement of the articles along the rails, as the rockers and fingers are sequentially pivoted by the drawbars.

Abstract: A refrigerated food is packaged in a paperboard tray covered by a plastic film bonded to upper edges of the tray sidewalls in provision of a barrier against contamination of the food. The film and the tray are transparent to microwave energy for heating the food, and automatic venting of the covered tray, while heating, is afforded by a relatively small strip of electrically conductive material on the film and absorptive of microwave energy in an amount sufficient to heat the same and melt a vent opening in the film.

Abstract: Ink compositions are provided which are suitable for use in ink jet printing on coated or uncoated substrates to form images which are highly resistant to abrasion and highly penetrant by virtue of the penetrating characteristics of a select solvent system. The ink compositions have improved handling safety and performance characteristics, and contain, in a preferred embodiment a penetrating solvent blend comprised of from about 50 to 90% n-propyl acetate as a major solvent, methyl cellosolve as a high boiling secondary solvent, and, as an auxiliary solvent a lower aliphatic alcohol; from about 3 to 25% by weight of a low molecular weight B or C-stage, modified phenol polymers; a colorant; an electrolyte; and optionally, a surfactant.

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: A process for conditioning ferruous particles with heat and a reducing atmosphere to reduce the oxygen content of the particles in a non-agglomerative manner and to make the conditioned particles readily pourable and free-flowing, and to process the particles into steel strip.

Abstract: A process for coloring nonwoven webs of fibrous material, particularly air-layed webs, in which solid, water insoluble particulate pigments are introduced and intermixed with the fibers of the web to provide the coloring thereof. An initial formed web of fibrous material has a suspension of insoluble pigment in a liquid applied thereto, is fiberized, and is reformed into a web and bonded with a binding liquid. Alternatively, the pigment may be mixed with the separated fibers after the fibrous material is fiberized and before reforming.

Abstract: A continuous process for effecting the acid hydrolysis of cellulosic waste materials, at high solids and in a most economically desirable manner. The process may be controlled to produce, as primary products, glucose, furfural and/or xylose. By appropriate control of water and temperature, through the use of direct steam injection, high solids feedstocks may quickly be converted, in good yields, to valuable products, thus making the process very attractive from a practical commercial standpoint.

Abstract: A wristwatch display carton is disclosed which includes a face panel, having a cut-out therein to receive the wristwatch, which is positioned at an inclined angle tilting into the interior of the carton so that wristwatch is partially sheltered by the top and sides of the carton. A pair of infolding flaps attached respectively to the opposed side panels aid in positioning the face panel within the carton. Four different embodiments of blanks from which the carton may be erected are disclosed.

Abstract: A flexible heat sealable packaging material including a flexible web of substrate material, a normally tacky heat sealable wax composition on the surface of the substrate, and a non-blocking coating applied as a hot melt over the heat sealable layer which has good release properties with respect to itself and to the non-coated side of the substrate. The non-blocking coating melts at the heat sealing temperatures to allow the underlying heat sealable material to pass therethrough and complete the seal.

Abstract: Multiple distributor heads of the Kroyer type in side-by-side position over a common suction tunnel for laying fibrous material onto a foraminous forming-wire screen travelling along the tunnel.

Abstract: A flexible packaging sheet material bearing a tacky wax composition coating and a non-blocking overcoating in the form of a continuous film of an ethylene-vinyl acetate copolymer which incorporates between 10 and 35 percent by weight of solid low to medium density polyethylene particles of a size smaller than about 50 microns.

Abstract: A process for conditioning ferrous particles with heat and a reducing atmosphere to reduce the oxygen content of the particles in a non-agglomerative manner and to make the conditioned particles readily pourable and free-flowing, and to process the particles into steel strip.

Abstract: A resin blend for producing a peelable heat seal, which does not produce "angel hair" upon separation, includes polybutylene and a copolymer of ethylene with, for example, vinylacetate or methyl acrylate. Typical substrates are high density polyethylene and nylon.

Abstract: Two spray coatings are successively applied, without an intervening curing step, to coat the inside surface of a shell for a two-piece can. This "wet-on-wet" coating technique utilizes zone spraying, wherein only the sidewall is covered during the first application, with the second coat being applied to all inside surfaces.

Abstract: Melt extrudable polypropylene-polystyrene compositions are provided which are particularly suitable for use in extrusion coating. Substrates coated with such compositions as well as methods of producing such coated substrates are also provided.

Abstract: A container having a tray portion and a cover sealed to the peripheral top edges of the tray. Cut score lines on the inner side of the cover provide a splitting of the paperboard of the cover upon opening to allow the cover to be peeled from the tray to a hinge at the back edge of the tray. Offset double cut score lines may be provided on the upper and lower sides of the cover at the front edge of the tray, which will split upon opening of the cover to yield overlapping locking flaps which can be used to reclose the cover. Flanges may be attached to the lateral side edges of a paperboard tray by cut score hinges, and adhered to the inner side of the cover to provide layer separation of the flanges upon opening rather than layer separation of the cover. Alternatively, double cut score lines can be formed along the lateral sides of the cover in position to register with lateral side flanges on the tray, which split and provide overlapping locking flaps when the cover is opened.

Abstract: Valuable new and widely useful compositions of matter are comprised of products having enhanced solubility and increased dispersant and the like surfactant activity which products are ozonated lignosulfonate derivatives beneficially including ozonated units of alkaline oxidized, hydrolyzed lignosulfonates, including sulfonated, partially desulfonated and resulfonated lignosulfonates.

Abstract: A blister package comprises an insert including a blister, and a carton within which the insert is contained. Locking tabs formed from a section of the top wall panel of the carton project inwardly and into engagement with a laterally extending bearing surface provided on the insert. The tabs constrain the insert against the bottom wall panel of the carton, but permit the insert to be slideably disengaged therefrom.
