Abstract
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.

245 words
A system for measuring the true outer diameter of a cable, including a stationary chamber having oppositely disposed apertures in opposite walls thereof, said cable being positioned in the chamber between the apertures, oppositely disposed window units in opposite sides of said chamber in line with said apertures therein and spaced from said chamber making the interior thereof visible from the exterior of said chamber, said cable being positioned between said window units, said window units including oblong shaped elements which are formed of transparent material, the interior of said chamber being subjected to steam, mounting means for connecting said window units to said chamber in spaced relation thereto and said mounting means includes a steam injection unit comprising a pipe extending into said area and extending therein to substantially the lower end of said oblong shaped transparent element, said pipe including a series of spaced apart perforations in the length thereof adjacent to said oblong shaped transparent element, the perforations being directed toward said oblong shaped transparent element directing steam in a linear pattern thereagainst said cable having had insulation applied thereto in a saturated steam atmosphere and mechanism connected to said cable causing travel thereof from and out of the saturated steam atmosphere and through said chamber, said cable traveling through said chamber at any point therein within the projected plane of said transparent oblong shaped element, whereby said cable will be visible at any such point through said transparent oblong shaped element.
