Abstract: A fastener assembly includes a row of fasteners having a head, a tip, and a portion of a shank coated with a polymer composition. The polymer composition includes a polymer material such as polyurethane and metal particles. The polymer composition is used to provide improved corrosion and ultraviolet radiation resistance when used with naturally corrosive or pressure preservative treated wood. The fastener assembly is coated with the polymer composition by vacuum coating a dispersion of the polymer composition in a solvent such as water and removing the solvent.

Abstract: A quick release and connect nozzle assembly for use with a material dispensing head including a nozzle engagement member on a portion of the dispensing head, a nozzle member having an aperture therethrough for operable communication with the dispensing head to provide dispensing of the material in a predetermined pattern, and a connecting member integral with the nozzle member for engagement with the engagement member of the dispensing head, wherein the connecting member is operable by hand and provides quick release and connection of the nozzle member from the dispensing head so as to enable cleaning or replacement of the nozzle member as desired.

Abstract: A method for preparing polycrystalline lithium metal oxide fibers of the formula Li.sub.x M.sub.y O.sub.z by filling micromold fibers of a desired inner diameter and length with a mixture composed of the desired metal salts or solutions of salts or alkoxides, solvents, binders, plasticizers, and deflocculants, firing the filled micromold fibers at elevated temperatures but below temperatures of lithium oxide volatilization in air for at least one hour to simultaneously burn-out the micromold and yield the polycrystalline lithium metal oxide fiber.

Abstract: An easy-open container includes a membrane forming the top edge of the container and hermetically sealing the contents thereof. Elements for opening the container are disposed on the membrane, and includes a first bead of thermoplastic material and a first perforated line for tearing across the membrane. In one embodiment the membrane is disposed inward from the mouth of the bag, leaving portions of the bag walls extending upward beyond the container top edge to form guide rails which facilitate opening of the container. One guide rail is removed as the bag is opened and remaining portions of the bag walls are offset to enhance access to the bag contents. A membrane for sealing the mouth opening of a bag-like structure is also provided, as are methods for making an easy-open container and for making a membrane having the strcutures aforesaid.

The membrane is disposed inward from the mouth of the bag, leaving portions of the bag walls extending upward beyond the container top edge to form guide rails which facilitate opening of the container to gain access to the bag contents. A membrane for sealing the mouth opening of a bag-like structure. A method for making a membrane as aforesaid and a method for making an easy-open container having the structure aforesaid are also provided.

Abstract: Dual flexible plastic pouches and a method of making the pouches where the pouches are reuseable and reclosable and have a double fastener strip arranged along the center between the pouches, the double strip is formed with a lower layer and upper pull flanges folded in from the edge of the lower layer with the pull flanges having reclosable rib and groove elements between the flanges and lower layer, an upper film web is juxtaposed over the lower web and bonded thereto over the peripheral edge to form pouches, the flanges are heat sealed to the upper web with a heat blocking thermal barrier between the flanges and lower layer of the fastener to prevent unintentional bonding.

Abstract: A method of forming a series of tray containers from plastic sheet film including intermittently continuously advancing a sheet of film, forming pockets in the film by heating and pressure differential across the film, laterally delivering closure strips between the pockets with the closure strips doubled, and having upper and lower layers with rib and groove fastener profiles therebetween, attaching the lower layer of the fastener to the web at the upper and lower edges of the fastener, laying an upper layer of film over the lower layer and attaching it to the lower layer around the edges of the pockets and attaching the upper layer of film to the top edge of the doubled fastener strip with the upper layer of the fastener strip having a tear perforation sealed by a sealing strip below the rib and groove elements.

Abstract: Zippered material for packages comprising a zipper strip having longitudinally extending complementary reclosable interlockable zipper profiles with a web separating the profiles. In one aspect, the strip is notched out to the web from opposite sides at package section intervals and with limited respective areas of the web providing links connecting the sections of the strip at the notches, the links being sealed and flattened onto package making sheet material. In another aspect, the web and the material have matching lines of weakening, the web is hermetically bonded to the material and at least the line of weakening of the web is hermetically sealed to prevent leakage through the lines of weakening, but enabling tear-open separation along the lines of weakening.

Abstract: A method of preparing a purified ammoniated phosphoric acid composition, comprising, reacting an aqueous wet process phosphoric acid with an ammonium ion source at a N/P.sub.2 O.sub.5 weight ratio ranging from about 0.06 to about 0.15 in the presence of solid phase metal ion containing impurities for a time sufficient to precipitate the majority of the impurities in the acid, the impurity precipitation comprising at least several complex metal salts at least one of which contains magnesium, aluminum and fluorine, and obtaining the purified ammoniated phosphoric acid by separating the precipitated impurities therefrom.

Abstract: Magnesium and aluminum impurities may be removed from wet process phosphoric acid by adding a fluoride ion donating compound, such as hydrofluoric acid, for example, to thereby provide about four fluoride ions for each aluminum ion. Also, preferably, an aluminum ion donating compound, such as alum is added to the wet process acid to bring the aluminum ion to magnesium ion ratio up to about two to one to facilitate formation of crystalline compounds having the general stoichiometry MgAl.sub.2 F.sub.8. The treated filter grade acid is then further treated in a crystallizer to form large crystals which will readily precipitate so the purified liquid phase, low in magnesium and aluminum containing impurities, may be separated from the crystalline phase.
