Abstract: 1,048,219. Ignition systems. RADIO CORPORATION OF AMERICA. Dec. 10, 1964 [Dec. 31, 1963], No. 50379/64. Heading FIB. A current regulating arrangement for an ignition system of the type wherein current from a voltage source 12 flows through a ballast resistor 18 the emitter-collector path of a first transistor T1 controlled by a pair of breaker points 36, 38 and the primary winding 20 of an ignition transformer, comprises a variable impedance device connected in parallel with the ballast resistor, voltage sensing means connected to the voltage source and biasing means connected to the variable impedance device and controlled by the voltage sensing means in a sense so that the impedance of the variable impedance device increases and decreases as the voltage of the source respectively increases and decreases. Under heavy load on the battery 12 the voltage of the battery drops to say 8 volts. The voltage across the resistor 56 is now insufficient to bias the transistor T3 into conduction and the transistor T2 conducts fully. Current from the battery 12 now flows to the primary winding 20 through the parallel paths provided by the ballast resistor 18 and the regulatory resistor 52 provided the breaker points are closed. Sufficient current can flow to the primary winding 20 even though the voltage of the battery 12 is lowered under starting conditions. As the voltage of the battery 12 increases from 8 to 10 volts the impedance of the transistor T2 increases so that the current available to the primary winding 20 remains substantially constant. When the battery voltage is 12 volt the transistor T3 may be turned fully-on biasing the transistor T2 fully off.

After passing the junction the followers are switched over so that the left-hand guide is again engaged. The vehicle is driven by a linear induction motor including a track mounted aluminium plate 40a or 40b which reacts with the magnetic field set up in vehicle-carried coils 42a or 42b. The left- or right-hand arrangement is used depending on which follower is engaged with its associated guide surface. At points where routes converge, Fig. 4, a vehicle on the left track is guided by the left guide surface and a vehicle on the right track is switched over to guidance by a right-hand guide surface in approach to the junction and then switched to the left guide surface after passing the junction. Sensing surfaces 15, 16 are provided on the front and sides of each vehicle so that assuming two vehicles 19, 20, Fig. 6, approach a converging junction the side of the leading vehicle 20 is engaged by the front of the second vehicle 19 and as a result of the engagement the leading vehicle is accelerated and the second vehicle is retarded to allow the leading vehicle to reach the junction first. The same system is used to retard a following vehicle if its front sensing surface engages a vehicle in advance. The track elements and associated vehicle apparatus which trigger the shift of the followers in dependance on the guidance programme may be an electromagnetic wave or sound transmission system or may be an electric contact engaging arrangement.
