Abstract: 581,328. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. April 28, 1943, No. 6744. [Class 40 (v)] A multi-vibrator for generating a train of uni-directional pulses synchronised on a submultiple of a controlling wave, is provided with means for deriving further synchronising pulses at the sub-multiple frequency which together with the controlling wave effect the synchronising of the circuit. The Figure shows the application to a multi-vibrator which may be of the type disclosed in Specification 578,690 and is modified by connecting in series with resistance .R8 which defines the frequency, transformer T connected to the controlling wave and resistance R9 in parallel with delay networks DN1, DN2, which may be non-dissipative transmission lines. In this way the synchronizing pulse for the (n+1)th pulse is obtained from the nth pulse generated across resistance R9 by reflection in the open delay network DN1 and an inverted pulse is obtained from the network DN2 slightly later so as to shorten the synchronising pulse. Triode valves may be used and the cross-coupling condenserresistance networks may have differing time constants, the grid associated with the circuit having the longer time-constant network having the synchronising pulses applied thereto. The controlling wave is preferably sinusoidal and the auxiliary synchronisation is preferably arranged to be effective when the controlling sinusoidal wave is passing through zero.
