Abstract

827,844. Glass composition. CIANCRI, A. L. G. Dec. 9, 1955 [Sept. 9, 1954], No. 26133/54. Drawings to Specification. Class 56. [Also in Group XXXVI]. A glass having the same coefficient of expansion as copper has the following composition : PbO 10-30%; SiO 2 10-30% ; ZrO 2 5-20% ; Al 2 O 3 2-10% ; MoO 2 1-5% ; TiO 2 1-5%; LiO 2 1-5%; Na 2 O 1-5% ; K 2 0 1-0À1%. The glass is used for making a seal between a wire &c. and a second part (see Group XXXVI). Specification 603,489 [Group XXXVI] is referred to.
