Abstract

493,671. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd. Dec. 3, 1937, No. 33553. Convention date, Dec. 5, 1936. [Class 40 (iv)] [Also in Group XL] In a repeater comprising a negative feedback amplifier, provision is made for heating the valves over the lines L, L1 from a battery 14 with earth return. Also, the application of negative feed-back amplifiers to two-way repeaters is described with reference to Fig. 2B (not shown). Specification 458,565, [Group XL], is referred to.
