Abstract: A method employing at least one separation roller continuously contacting the outside surface of a web and tracked to move in a fixed approximately elliptical path for compensating for web motion during separation of the web from another surface to enable a bead of accumulated material built up at the line of contact between the web and the other surface to pass therebetween without changing the web velocity. In a preferred embodiment, the system is employed in photoelectrophoretic imaging to bypass a bead of imaging suspension built up at the imaging nip during separation of two webs immediately after completion of imaging to thereby permit dissipation or passage of the liquid bead without changing the advancing web velocity.

Abstract: Vinyl polycyclic aromatics, particularly polycyclics having 3 or more nuclei and their polymers utilizable as active matrix material for xerographic purposes are obtained in high yield by initial conversion of the polycyclic reactant to the aldehyde in the presence of a haloalkyl ether as a formulating agent in the presence of a Friedl-Crafts type catalyst. The aldehyde intermediate is then converted to the vinyl monomer by using a Wittig-type reaction and, thereafter, polymerized, as desired, by the use of a cationic mechanism.
