An inductive signalling system in a funicular railway or the like utilizes the movable traction cable loop co-operating with the fixed and movable stations, a first service signal being transmitted by altering by equal and opposite amounts the amplitudes of two currents of different frequency which in the absence of service signals are of equal amplitude, a second service signal being transmitted by altering the amplitudes by equal amounts in the opposite sense to that for the first service signal, and means being provided whereby telephone signals also may be transmitted via the loop. The inductive coupling is provided by transformers through which the traction cable passes. Various coding arrangements for " start," " stop " and " emergency " signals and an extension of the system to the public telephone service are described. The traction cables may be checked to give warning of contact with a carrying cable and the transmission channels tested by checking the constancy of the sum of the amplitudes of the pairs of frequencies, or by determining the change of resistance of the traction cables.

Abstract: 1305519 Electromagnetic brakes; non- frictional track-brakes on rail vehicle M BAERMANN 16 July 1971 [18 July 1970] 33536/71 Heading F2E An eddy current and hysteresis brake for rail vehicles comprises an iron core having a pluralty of pole legs joined by a yoke and coils arranged on the individual legs to produce, when energized, poles of alternating polarity in the pole legs; the protruding part of the each pole leg forms a pole head, and the thicknesses of the pole heads and pole legs and the inter-pole leg spacing in the direction of motion of the vehicle are specified, with limits; spacing means are provided to maintain a constant air gap between the pole surfaces and the parts in which eddy currents and hysteresis work are produced. Fig. 2 shows a casing 5 incorporating pole legs 21 (the energizing coils not being shown), supported on a spring-mounted part of the vehicle 2 by a bar 15, the assembly being displaced downwards into the operative position shown by a pneumatically-operated piston 18. Wheels 22 which roll on the track normally maintain constant the air gap 21, but at turnouts and similar places on the track where the wheels are unsupported, wear-resisting end skids 14, whose lower surfaces lie between the levels of the wheels 22 and the pole heads slide on the track, are provided. In Figs. 6 and 7 a large winding space is obtained by making the direction-of-motion dimension a of the wound part 27 of pole-leg 20 less than the equivalent dimension b of polehead 28. But to ensure that the magnetic flux crosssectional area of the wound part is at least equal to the cross-sectional area of the polehead, transverse dimension d, Fig. 7, is made greater than dimension e. A cooling body 30 with cooling ribs 31 is provided. The poleheads are preferably welded or soldered in a plate 29 made of non-magnetic alloy (composition exemplified in the Specification). Fig. 8 shows the application of the invention to a wheel instead of to the track, pole surfaces 11 of pole legs 20 of brakes 1 being spaced from lateral faces 34 by an air gap 21 on both sides of wheel rim 33. The yoke (25), (Fig. 9, not shown), is arcuate and covers one third of the rim. The pole surfaces may alternatively face the wheel treads.  In the truck of Fig. 10 brakes 1 of the invention face the rails 10 somewhat as in Fig. 2, brakes 1a to 1h face the wheel rims as in Fig. 8, and the energizing current is provided by a generator 45 driven by an axle through gearing 46. As shown all the brakes are connected in series but they may be connected partly in series and partly in parallel. The stator configuration of the generator may be varied to adjust the energizing current by a compressedair actuator 47, 48. Disc brakes 51, 52 may be provided on the axles 40.  The energizing current may be controlled (e.g. by centrifugally-controlled resistors), so that when driving speed is reduced the magnetic attraction does not exceed the allowable bearing load.

Abstract: 958,865. Transistor amplifier circuits and switching. AMERICAN DISTRICT TELEGRAPH CO. Sept. 4, 1962 [Sept. 7, 1961], No. 33815/62. Heading H3T. [Also in Division G4] A low noise transistor amplifier used in an electrical protection system (see Division G4), has its input supplied via a transformer 44 to the base of the first of six NPN transistors 47- 52, the output being taken from the collector of transistor 52. The transistors are directly collector-base coupled, and each has a resistor 79-83 giving feedback from its collector to base. The overall amplifier is provided with negative feedback via a PNP transistor 74 and a resistor 53. To ensure that the amplifier gives greater amplification in the range 3- 10 kc/s., resistors 84, 85 and condenser 86. are included giving greater feedback at frequencies below 3 kc/s. and condenser 87 is included, giving greater feedback above 10 kc/s. The circuit may be energized from an A.C. supply through the rectifiers 61-64 stabilized by the Zener diode 65. Also included in the system is a unijunction transistor or double-based diode 99 (see Fig. 5), to the emitter of which is applied a voltage derived either from an integrator and differentiator circuit through a diode 96 or through a diode 103 from a low-gain wide band amplifier including the transistors 106, 112. The double-base diode conducts when the voltage between its emitter and base B1 exceeds a certain percentage (about 60) of the voltage between the two bases B1 and B2, and the coil 97 of a relay in the emitter circuit is then actuated so that an alarm signal may be given when the voltage input to the circuit exceeds a predetermined value. An alternative arrangement to this is described (Fig. 6, not shown), using a field effect transistor, with the relay coil in the collector circuit.
