Abstract: An apparatus for the in-line annealing of amorphous strip includes feed rolls for substantially continuously feeding the strip during annealing. The strip is first fed into a nip of cooperating heated pressure rolls. The heated pressure rolls rapidly heat the strip to an annealing temperature at a rate of substantially 10.sup.2 -10.sup.4 .degree.C./second while also subjecting the strip to localized plastic deformation. Where multiple ribbons are being fed simultaneously through the heating pressure rolls, bonding occurs to produce a composite strip. The strip is fed from the pressure rolls through an in-line annealer immediately downstream from the pressure rolls. During annealing, the strip is continuously fed and maintained under tension by operation of a winding roll. The strip is annealed at a temperature of between 420.degree.-510.degree. C. for 0.01-10.0 minutes.

Abstract: This invention relates to the production of large shapes of metallic glass fabricated from ribbon. The inventive method contemplates placing the ribbon and consolidating the alloy under a pressure or at least 1000 psi at a temperature of between 70% and 90% of the crystallization temperature for a time sufficient to facilitate bonding of the ribbons.

Abstract: Particulate polytetrafluoroethylene dispersion resin characterized by high molecular weight, relatively large particle size, uniform spherical particle shape and narrow particle size distribution, which is suitable for making stable concentrated aqueous polytetrafluoroethylene dispersions of concentrations higher than heretofore available, is made by polymerization of tetrafluoroethylene in aqueous dispersion in the conjoint presence of liquid octafluorocyclobutane and certain polyfluorinated carboxylic acid salt dispersing agents, using water-soluble peroxide initiators.
