Abstract: A method and apparatus for blending a material feed and/or separating debris from a material feed is disclosed in which a feed separator is used with a blender and/or debris separator. The feed separator separates a feed from the conveying air flow which conveys the feed and the conveying air flow, devoid of feed, is then used to blend the conveyed feed and/or separate debris therefrom.

Abstract: Apparatus for blending solid particulate material which includes a center lift or blending column with gaseous fluid under pressure supplied to the bottom of the column for entraining material in the vessel and lifting it up through the column to circulate material within the vessel. Recycle channels are provided on the periphery of the vessel for withdrawing material at various heights and supplying it to the bottom of the vessel for recirculation through the lift column. Each of the recycled channels includes a plurality of vertically spaced apart inlet openings each with a baffle positioned therein to permit material to simultaneously enter the recycle channel at more than one point along the height of the vessel. These baffles may be equipped with operators to selectively position the baffle to control the flow of material into the recycle channel. The apparatus also includes an arrangement defining a seal leg at the bottom of the vessel to ensure proper recycle of material through the apparatus.

Abstract: Disclosed is a polyetherimide ester composition comprising at least one polyetherimide ester resin and a modifier composition which is comprised of a modifying amount of at least one multifunctional epoxy resin. The modifier composition may optionally also include a thio ester and a hindered phenol.

Abstract: Thermoplastic polymeric amides are disclosed which have utility as hot melt adhesive compounds. The compounds are the reaction product of a polyoxyalkylene diimide diacid and a diamine.

Abstract: Novel thermoplastic elastomeric molding compositions having excellent physical properties, which comprise a polyetherimide ester elastomer modified with a combination of poly(butylene terephthalate), a monoalkenyl arene-conjugated diene copolymer and a polycarbonate.

Abstract: Novel thermoplastic elastomeric molding compositions having excellent physical properties, which comprise a blend of a polyetherimide ester elastomer and a polycarbonate resin.

Abstract: The present invention discloses a method of photolytically developing a walnut wood color on a wood sample. The sample is contacted with a salt of an aminobenzenesulfonyl azide. The sample is thereafter exposed to a light source for an amount of time sufficient to produce a walnut wood color thereon.

Abstract: This invention pertains to a method and apparatus for producing a cured resinous coating which exhibits a reduced gloss level. In a preferred embodiment, the cured resinous coating which exhibits a reduced gloss level is a wear resistant coating and is superimposed on a resilient floor covering material.

Abstract: An aqueous-based nylon fiber shrinking composition which can be formulated into a print paste is disclosed. The resulting print paste exhibits excellent viscosity stability and can be applied to nylon pile fabric to produce print-embossed pattern fabric.

Abstract: An improved process for forming a friction material having metal fibers evenly dispersed in the body of the material. The raw materials for production of the friction material are dispersed in an aqueous slurry. The slurry is formed into a sheet. This sheet is subsequently cured and cut to form brake pads and related friction materials.

Abstract: 3,4,5-Tris(4-pyridinylthio)-2,6-pyridinedicarbonitrile is prepared by reacting three molar proportions of 4-alkali metal mercaptopyridine with one molar proportion of 3,4,5-trihalo-2,6-pyridinedicarbonitrile. The product has antimicrobial utility.
