Abstract: A method and article providing different images from differing viewing angles. The image side of a lenticular sheet is printed with radiation sensitive image layer and cured using a collimated radiation source located at a viewer position with respect to the lenticular surface. Uncured imaging material is removed from the printed surface as by rinsing, and the resulting clear region of the imaging surface may be processed further in a variety of ways. The clear region may be left unprinted, or printed with a second image different from the first, or printed with a stereoscopic image that combines with its pre-printed mate to form a three dimensional image. The clear region also may be vacuum metallized or chemically plated to form a highly reflective surface. The method permits use of relatively thin lenticular sheeting.

Abstract: A method for fabricating laminations of mica and conductive foils of particular utility in constructing apparatus for generating ions in air. A layer of mica is laminated to sheets of metallic foil using a thermoplastic adhesive. The foil is etched in order to form electrodes in a prescribed pattern. The mica-foil laminate may be appended to additional structures to interface actuating electronics, provide a heat sink, and for other purposes. The preferred bonding material is a thin film of thermoplastic organopolysiloxane adhesive.

Abstract: An apparatus and method for sampling condensate from a vacuum chamber employing a positive displacement pump, a pulsation dampener having sufficient volumetric flexibility to substantially dampen the pump's pressure surge, and a pressure regulating valve. The apparatus can be used in conjunction with sodium detectors, ion exchange analyzers, conductivity cells and other contaminant monitoring devices.

Abstract: A method is disclosed for fabricating laminations of mica and conductive foils for generation of ions in air. A layer of mica is laminated to sheets of metallic foil using pressure sensitive adhesive as the bonding material. The foil is etched in order to form electrodes in a desired pattern. The mica-foil laminate may include an encapsulating layer or tape of pressure sensitive adhesive around the edges.
