Rossetti discloses an apparatus for making cast polymer
sheets (col. 1, lines 11-13). The apparatus includes a
housing having therein a number of hollow metal plates which
are in a substantially vertical, parallel orientation and are
laterally moveable (col. 2, lines 32-41; col. 4, line 64 -
col. 5, line 10). Each pair of hollow metal plates has
therebetween a pair of glass plates, wherein each glass plate
is detachably attached to a surface of a hollow metal plate
(col. 2, lines 45-51; col. 5, lines 11-16). The hollow metal
plates have spacers to facilitate adjustment of the distance
to the next metal plate and thereby adjust the distance
between the glass plates (col. 3, lines 9-12; col. 6, lines
55-58). After the spacers have been adjusted and casting
liquid pored into the glass molds, the entire assembly is
pushed together in the manner of a filter press (col. 3, lines
13-17; col. 6, line 55 - col. 7, line 15). During
polymerization, fluid flows through the hollow metal plates to
maintain a uniform temperature distribution (col. 3, lines 28-
36).
