Abstract: Papermakers Fabric Using Differential Melt Yarns Abstract A papermakers fabric woven in accordance with a preselected weave pattern.  The fabric has a top surface, a bottom surface, and a center plane interposed between the top and bottom surfaces.  The fabric is woven using high melting point or high degradation temperature synthetic warp yarns and similarly high melting point or high degradation temperature synthetic top and bottom weft yarns.  The weft yarns in the center plane are lower melting point synthetic yarns.  During heat stabilization, the fabric is exposed to sufficient heat to cause the low melting point stuffer yarns to melt and flow, and to reform in such a way that they fill to a desired extent the voids in the weave pattern where they have been inserted, thus, reducing permeability.  The flow of the molten synthetic stuffer pick around and between the unmelted warp and weft yarns bonds the whole structure together, thereby improving fabric stability.  Finally, because the melted stuffer pick acts as a monofilament yarn, the fabric tends to run cleaner.

Abstract: ABSTRACT OF THE DISCLOSURE      A substantial amount of liquid lubricant used in a cold strip rolling mill is prevented from passing between the area of the work roll necks and work roll bodies not in contact with a strip by locating in a strip guiding means on the entry side adjacent both edges of the strip, several zoned air nozzles which delivery a positive pressure to force the liquid away from this area, in a direction toward the center of the strip and rolls, and which nozzles are controlled according to the width of strip being rolled.          The relatively small amount of liquid finding its way onto the delivery side is removed from the strip by providing in the strip guiding means both positive and negative air pressure means located above and below the strip, and negatively pressurized longitudinal enclosures located adjacent both edges of the strip and the said area.

Abstract: CONTROL OF COLLIDING ION BEAMS     ABSTRACT OF THE DISCLOSURE      A fusion reaction system is provided wherein ions from two sources are forced by passage through magnetic and electric fields to travel toward each other in opposite senses and directions under con-finement to common helical paths at a common radius in a cylindrical reaction zone by radial electric fields.  The ions are bunched along said helical paths to establish a plurality of concentrations of the ions located at spaced points along the paths with the points being the same for ions from both sources.  Structure in the reaction zone is arranged for establishing local variations in the radial electric fields to produce the localized concen-trations of ions as they traverse their helical paths.  Further, means may be provided to velocity modulate the ion sources for producing standing waves along the reaction paths having velocity nodes located at points in the reaction zone where the localized concentrations occur.  Variable voltage sources are connected to modulate the velocities of ions from the two sources for producing standing waves in the reaction zone having velocity nodes spaced the same as the spacing between the localized concentrations.  Phase adjustment means provide for positioning the velocity nodes at the same points as the points at which the localized concentrations occur.
