摘要:
A nail has a head, a penetrating tip and a shank extending from the head to the penetrating tip. The shank has a circumference and a longitudinal axis. A plurality of rows of deformations formed as teeth are formed in the shank extending outwardly of the shank. The rows are formed in a spiral pattern along the length of the shank from about the head to about the penetrating tip. The rows of teeth are formed parallel to one another and formed at an angle of at least 50 degrees relative to a cross-sectional plane perpendicular to a longitudinal axis of the nail.

Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.

Described herein are silyl monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. Such multimer forming associations of monomers may be promoted by the proximal binding of the monomers to their target biomolecule(s). In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element.

A method of preparing C-5 substituted nucleotides by reacting a C-5 posit mercurated nucleoside with an alkyl or aryl disulfide in the presence of palladium(II) ion. The resulting new method for attaching linker arms to nucleic acids (DNA,RNA) provides a wide ranging reaction far more useful than those heretofore developed, and allows preparation of modified components with linking reactive functionality that allows usefulness as probes, therapeutics, and for DNA sequencing.

摘要:
An apparatus for forming a plastic molded collated fastener assembly includes a conveyor for carrying a plurality of fasteners in a horizontal plane defining an upper surface and a lower surface, a preheater for preheating the plurality of nails and a plastic collation molding station. The molding station includes injection nozzles for applying molten plastic to the upper surface of the fasteners and to the lower surface of the fasteners. The station further includes forming wheels including a holding section to, in cooperation with the conveyor, secure the fasteners. The wheels include a forming section to mold the molten plastic to the fasteners to form a collation having a collar encircling the fasteners' shanks and a connecting portion extending between the collars. The apparatus includes at least one cooling spray nozzle to spray a cooling vapor onto the fasteners and collations and at least one cooling spray nozzle to spray a cooling vapor onto the forming wheels. An air chiller further cools the collations.
摘要:
A fastener assembly is configured for use in an associated fastener driving tool for driving a fastener from the assembly into an associated substrate. The assembly includes a row of fasteners, each having a shank, arranged substantially parallel to each other. A collation system is formed from a plastic material that is molded onto and adhered to the fasteners. The plastic material is molded to define a collar portion substantially encircling the fastener shank and a connecting portion extending between and connecting adjacent collar potions. The plastic material is formulated from an adhesive polymer. When the fastener is driven from the driving tool, the collar portion remains adhered to the fastener such that the collar portion penetrates the substrate with the fastener.
