Abstract

1314693 Variable phase shifters BROWN BOVERI & CIE AG 22 Oct 1970 [4 Nov 1969] 50220/70 Heading H1W [Also in Division H4] A device for producing differential phaseshift between two short-wave (10-100 m.) transmission lines comprises a line-stretcher in which the telescopic sections 10, 10<SP>1</SP>, 11, 11<SP>1</SP>, 12 of one line are extended whilst those of the other line (similarly referenced) are retracted. The U-sections 12 of both lines are connected to a partition 16 movable within a housing 9 by means of a cable 19. The lines may connect two antennae to a common transmitter and the phase-change used for beam sweeping.
