Abstract
1,229,948. Conductive glass; joining glass to glass. FERRANTI Ltd. 3 Nov., 1969 [9 Nov., 1968], No. 53200/68. Heading C1M. [Also in Division H1] ' Electrically resistive material 18 placed in each cavity 15 of a block 12 in a gas-filled display device (see Division H1) is an electronically conducting glass having the composition in mole per cent of 60% V 2 O 5 , 30% ZnO and 10% B 2 0 3 or 73% V 2 O 5 , 20% P 2 0 5 and 7% Fe 2 O 3 . Alternatively a glass-ceramic comprising a mixture of lead borosilicate and thallium oxide may be used. The device comprises blocks 10, 11, 12 and 13 and holes 14 in block 11 register with holes 15 in block 12, the blocks being sealed together by enamel 20 to give space for conductors 16 and 17. The coefficient of thermal expansion of glass 18 should be substantially the same as that of the block 12.
