Multicolored Aluminum Spiral for Paper Binding
20220371076 · 2022-11-24 ·

An article of manufacture for providing multi-colored aluminum spirals for document and book binding is disclosed. The article being a spiral made from a length of wire having a specified gauge that is processed by one or more drive rollers coupled to a forming machine using a method of manufacture. The method sets a pitch value for a manufactured spiral on a forming machine, sets a diameter value for the manufactured spiral on the forming machine, receives the length of wire by one or more drive rollers, processes the length of wire by the forming machine using the set pitch value and the set diameter value to create the spiral, dips a first portion of the spiral into a first anodizing solution, and dips one or more additional portions into additional anodizing solutions after the first anodizing solution has set.

Basket hanger

A basket hanger attached to a basket. The basket hanger having a hook with a plurality of spring steel wires strands extending from the hook, the spring steel wire strands having a substantially straight downwardly extending portion terminated at a distal end in a clip. Each clip positionable between an open position and a clipped position. In the clipped position, an upwardly extending leg of each of the clips extends through an opening in the peripheral flange of the basket such that the peripheral flange is received in an upward first bend of each of the clips, and a second bend of each of the clips engages a back side of the substantially straight downwardly extending portion such that a short dogleg partially wraps around the substantially straight downwardly extending portion.

Steel wire for bolt, bolt, and manufacturing processes therefor

A steel wire for high-strength bolts is used for a non heat-treatment bolt with an excellent cold forgeability for which quenching and tempering steps have been omitted after bolt formation, and which has a tensile strength of 1200 MPa or more and an excellent delayed fracture resistance. The steel wire includes C, Si, Mn, P, S, Cr, Al, N, and B, at least one selected from the group consisting of Ti, V, and Nb with the balance consisting of iron and inevitable impurities. The steel wire has a microstructure wherein ferrite and perlite have a total area rate of 98% or more, perlite lamellar spacing is 250 nm or less, and an area rate of the perlite is more than 40%, and 80% or less. The steel wire has a tensile strength of 1300 MPa or less.
