Patent FR-958759-A (FR)
IPC: H04L25/49
Granted: 1950-03-17
Abstract: 656,184. Electric signalling systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 30, 1947, No. 34844. Convention date, Aug. 22, 1944. [Class 40 (i)] [Also in Group XXXIX] A receiver for responding selectively to a potential applied to a signalling wire comprises a chain of four valves BA ... BD with relays A ... D in their anode circuits, the grid bias of the valves being derived from a potentiometer including resistances which are switched in and out by relays B ... D to shift the bias of the valves earlier in the chain, with the result that different combinations of relays are operated as the signalling potential is varied in steps. As shown, the signalling potential is variable from a normal value of - 30 volts by steps of - 2 volts to - 60 volts, and the valves, which are pentodes, have a normal bias of - 32, - 34, - 38 and - 46 volts respectively. A signalling potential of - 32 volts operates A, whereas a potential of - 34 or - 36 volts operates B which immediately makes the bias of BA 4 volts more negative, so that A operates only in the latter case. In the same way, the operation of C by a potential of - 38 to - 44 volts alters the bias of both BA and BB to determine the potential more accurately. The relays A, B, C have opposing windings in series respectively with operating windings of B, C, D, thereby preventing momentary and possibly false operation of, say A, by a signalling voltage sufficient to operate B ; the possible operation of A being delayed until B has shifted the bias on BA, whereupon the opposing winding of A is short-circuited and A may operate if the signalling voltage and the new bias bear the correct relationship. Specification 655,369 is referred to.

Abstract: An electric motor 12 operates a transmission 12a, 12b having an output element which is biassed by energy storing means, eg a spring, that when the electric motor 12 is in an idle condition, eg turned-off at least partially engages a clutch so as to transmit a nominal torque which is less than a nominal torque produced by a power train. The electric motor 12 is electronically controlled and may have a transmission in the form of multi-stage gearing, such as worm and crank gearing 12a, 12b operating the clutch through a fluid column 8 or alternatively through linkwork (fig 1b) or directly (fig 27). The single or multi-stage gearing may include toothed gearing, eg epicyclic gearing (fig 30) or swashplate gearing (fig 33) or cam gearing (figs 18, 19) or rack-and-pinion gearing (fig 21). The gearing may be such that the ratio between the electric motor 12 and the clutch operating member will vary, eg by using non-circular gears (fig 22), the electronic control responds to signals such as engine speed, vehicle speed and an intent of a driver to change ratio.
