Abstract
790,363. Glass compositions. BRITISH THOMSON-HOUSTON CO., Ltd. May 20, 1955 [March 16, 1954], No. 7636/54. Class 56. [Also in Group XXXVI] A resistor having a negative temperature coefficient consists of a body of glass comprising at least 30 per cent by weight of V 2 O 5 . The remainder of the glass may consist of from 70 to 5 per cent of Pb 2 O 5 or 70-40 per cent of TeO 2 . Other examples of glass composition are (i) at least 70 per cent of V 2 O 5 , less than 10 per cent of PbO and not more than 20 per cent of Pb 2 O 5 , (ii) 74 per cent V 2 O 5 , 18À5 per cent P 2 O 5 and 7À5 per cent of PbO, and (iii) 83 per cent V 2 O 5 , 9 per cent P 2 O 5 and 8À0 per cent of PbO. Alkali metal oxides or alkaline earth metal oxides may be included in the glass. The glass may be cast between chrome-iron alloy sheets, which serve as electrodes, or the electrodes may be provided by spraying or evaporating metal on to separated regions of the body. Specifications 744,205, 744,947 and 746,192 are referred to.
