Transistors For London Buses
TRANSISTORS FOR LONDON BUSES
was the headline, 54 years ago, on a sotry in Electronics Weekly’s edition of September 14th 1960.
The story starts:
The new AEC Routemaster buses for London Transport are to be fitted with an AC generator set giving a 100% transistorised system of control.
The equipment is made by Simms Motor Units Ltd of East Finchley who claim to be the first manufacturers of automobile electrical equipment to introduce a unit of this type.
The company are making full use of semiconductors both for the rectification of the AC supply and for controlling the output.
Instead of the heavy, cumbersome equipment needed for rectification of AC to DC, a compact and lightweight box incorporating a germanium diode circuit now performs the operation.Tags: AEC Routemaster buses, LONDON BUSES, London Transport, Simms Motor Units Ltd of East Finchley, Transistors For London
