Abstract: A process for steam-sterilizing label-bearing containers stacked with the labels in contact, without destroying the labels such as occurs if the labels are printed by thermal transfer for product-variable data. The process features laser-ablating imagewise the label to remove an ink layer so as to expose either a contrasting ink layer below, or a metal foil or polymer substrate. Such containers are then readily stacked on the labels and sterilized without thermal damage to the labels.

Abstract: A priming agent composition useful for binding a layer containing a fluorocarbon polymeric material to a metallic or an organic polymeric substrate comprises about 98 to 99.99 weight percent of a crosslinked, glycidyl end-capped bisphenolic polymer and about 0.01 to 2 weight percent of a perfluoroalkylsubstituted glycidyl-reactive compound. A toner fuser member comprises a substrate to which a surface layer comprising an amorphous fluoroplastic material is adhered by an intervening layer comprising the described priming agent composition. The fuser member comprises metal or an organic polymeric material in the shape of a cylinder or, preferably, a belt.

Abstract: Concentric lens designs are disclosed for astigmatic presbyopes which comprise at least one surface which has a circular central portion and a plurality of concentric annular rings with at least three separate optical powers corresponding to a prescription for a patient and corresponding to 1) a basic distance spherical prescription Rx, 2) a near add spherical prescription Rx, and 3) a spherical prescription corresponding to the full, or preferably a fraction of the, cylindrical prescription Rx. An astigmatic presbyopic prescription contains an astigmatic correction, normally in the nature of a cylindrical prescription which specifies both the cylindrical optical power and the orientation of the cylindrical axis. The cylindrical prescription is taken into account in the design of the lens, but not with a cylindrical optical surface.
