Abstract:
A system for removing an interleaf sheet contacting a plate sheet used in an imaging system, comprised of a substantially horizontal member; an assembly comprising at least two elements configured to directly contact and pick up the interleaf sheet, a portion of said assembly connected to said member; a motor configured to move said member in a direction substantially perpendicular to a surface of the interleaf sheet as positioned prior to contact; and a first sensor system that generates a signal indicating when said member is a first predetermined distance from the interleaf sheet; and a second sensor system comprised of a second sensor that generates a signal indicating that the sheet beneath the second sensor is an interleaf sheet; said motor utilizing the first predetermined distance to move said member a second predetermined distance from the interleaf sheet, the at least two elements not contacting each other at the second predetermined distance, said motor moving said member in a direction toward the first predetermined distance to a position where at least a portion of the interleaf sheet is interposed between the at least two elements.
Abstract:
A curable, unsaturated polyester composition comprising, by weight, an unsaturated polyester and 1-60% styrene and 1-50% vinylether monomers.
Abstract:

Abstract:
A method for inhibiting corrosion of a metal surface bearing a corrosion product including ferrous ions is disclosed. The method comprises applying to the surface a salt of an ethoxylated amine and a reaction product of an alcohol and a fatty acid maleic anhydride adduct produced by a reaction between maleic anhydride and an unsaturated fatty acid. Related compositions are also disclosed.
Abstract:

Abstract:
This invention relates to epoxy vinyl ethers having the formula: ##STR1## wherein R is a polyvalent linear, branched or cyclic hydrocarbon radical having from 2 to 20 carbon atoms, optionally substituted with alkyleneoxy; n has a value of from 1 to 20; p has a value of from 1 to 6; and at least one of Y and Y' is ##STR2## while any remaining Y and Y' can be ##STR3## The invention also relates to the synthesis and uses of the above polyphenyl vinyl ethers.
Abstract:
This invention relates to a radiation curable crosslinkable composition containing (a) from about 0.1 to about 5 wt. % of an initiator containing at least 25% cationic initiator, (b) from about 0 to about 60 wt. % of a polymerizable vinyl ether, epoxide, vinyloxy alkyl urethane or acrylate and (c) from about 35 to about 99.9% wt. % of a polyfunctional alkenyl ether having the formulaA[(CH.sub.2 O).sub.m (Z).sub.r CH.dbd.CHR].sub.nwherein A is a carbon atom, --OCH.dbd.CHR or [C.sub.1 to C.sub.10 alkyl].sub.4-n ; R is C.sub.1 to C.sub.6 alkyl; Z is C.sub.2 to C.sub.8 alkyleneoxy; r has a value of from 0 to 6; m has a value of from 0 to 1 and at least one of r and m has a positive value; n has a value of from 1 to 4, with the proviso that m is 0 and n is one when A is --OCH.dbd.CHR, n has a value of 2 or 3 when A is [C.sub.1 to C.sub.10 alkyl].sub.4-n and n has a value of 4 when A is carbon. The invention also relates to the process of curing said composition and to a cured film on a substrate coated with the above composition.
Abstract:
The invention relates to a copolymer having the structure ##STR1## wherein R.sub.3 is lower alkyl or hydrogen; x is an integer having a value of from 100 to 15,000; R.sub.1 is a saturated radical or a radical having a terminal vinyl group and is selected from the group consisting of alkoxylated vinyl; alkoxylated alkanol; alkyl optionally substituted with one or more vinyl ether, alkylate,hydroxy or alkoxylated vinyl groups and phenyl optionally substituted with one or more lower alkyl, hydroxy, alkoxylate or alkoxylated vinyl groups.
