    摘要: In the operation of a plunger to form the yoke area of an article centrifugally formed in a mold, a ball and socket assembly is provided between the plunger and its associated spindle which permits the plunger to freely float from the formed glass article upon withdrawal of the plunger, thus obviating the production of crizzles and checks due to lateral pressure of the plunger on the side walls of the formed glass article.

    摘要: Glass for producing articles by centrifugal casting composed essentially of 60% SiO2, 18% B2O3, 7% MgO, 6% Li2O, 4% A12O3, 3% BaO, 1% CaO and 1% K2O, within tolerances of about + OR - 2 percent, all of the percentages being by weight; and article formed by helium-tight, stress-free fusion of the glass with an Fe-Ni-Co alloy.
