ABSTRACT:
A system involving a pair of oppositely disposed sight glass units wherein each unit includes an inner glass and an outer glass. One application of these sight glasses is in continuous vulcanization of multiconductor cables in a saturated steam atmosphere. The cable is steam wiped prior to its travel through a chamber between the sight glass units to remove accumulated condensation therefrom. Since the inner surfaces of the glasses of each sight glass unit may be clouded or dirty, wiping means is provided for each wet-side surface to provide and maintain clear and unobstructed viewing to permit scanning of the cable as it passes through the chamber between the sight glass units, and means for sealing the glasses in the units.
