Abstract: Improved apparatus for coating containers having a minimal separation between the body and the finish region comprises a coating hood and means for supplying coating materials to the coating. The improvement consists of a controlled non-turbulent air supply (18) directed downward across the coating-material stream (12). A blower (19) provides process air to a plenum (22), and an angled attenuator plate with a plurality of small holes distributes the process air evenly, to avoid standing waves and regions of high or low air velocity. Several attenuator plates can be juxtaposed to permit removal of particulates by movement of the plates relative to each other.

Abstract: An electrochromic element (10) useful in an electrochromic glass or mirror device and a process for making such element. The element is a five-layered structure including an electrolyte ion conducting layer (20) interposed between first and second inorganic electrochromic layers (16, 18) which are interposed between a pair of conductive electrodes (12, 14). The second inorganic electrochromic layer (18) is amorphous. The first and second inorganic electrochromic layers are different and are capable of exhibiting color-forming properties complementary to one another upon the incorporation of at least one H, Li, Na, K, Ag, Cu or Tl ion. The electrolyte ion conducting layer may be a copolymer of ethylene oxide, butylene oxide or methyl glycidyl ether, and optionally a small amount of allyl glycidyl ether, along with an ionizable salt, or may be a polyurethane gel formed by reacting the copolymer with triisocyanate, along with an ionizable salt. The second inorganic electrochromic layer comprises a transition element chalconide or halide. The electrochromic element may also comprise a plurality of five-layer structures in tandem, each pair separated by a substrate.

Abstract: Process for synthesizing 1,1,1-trifluoroethane (143a) in the gaseous phase by reacting 1,1-defluoro-1-chloroethane in gaseous phase in the presence of a Cr catalyst. The process may be run isothermally or adiabatically, without co-feeding air or other oxygen containing gas, in the presence or absence of a Ni, Co, Zn or Mn cocatalyst for the Cr catalyst. The catalyst may be unsupported or supported with a support preferably selected from activated carbon, alumina and fluorided alumina. The formation of olefin byproduct can be kept to less than 10 ppm in accordance with the process of the invention.
