    The number of simultaneous telephone calls that can be made across the Atlantic by satellite has increased from 240 in 1965 to several thousand; this is one result of the rapid development of satellite communication since 1962, when the first transatlantic television transmissions were made via TELSTAR. The article describes the beginnings of satellite communication, the present state of the art and possible future trends View full abstract»

    There is a need for a low-voltage d.c. supply in aircraft electrical systems; this is best provided from the a.c. system by means of transformer¿rectifier units since a separate d.c. generating system would impose a considerable weight penalty. The transformer-rectifier unit must be as small and as light as possible, yet it must operate within close performance limits. This article describesthe considerations relating to the design, construction and performance of such units View full abstract»

    Some new ideas on a project-based system of electronics teaching at the university are attracting attention in Germany. The advantages and disadvantages of these ideas, and the possibility of their extension to British universities, are discussed in this article, which begins by considering the world's oldest universities, along with European universities of the medieval period, and the effects that these early establishments have had on current trends in German university education View full abstract»

    Electric cars: the answer to today's noisy, fume-filled city streets if some improvements can be made to motors, controlgear and, particularly, batteries. The limitations of existing electric vehicles are pinpointed in the article, possible solutions are examined, and a new type of d.c. motor is described View full abstract»

    Induction motors have many advantages for industrial use, but the only simple and efficient way of controlling their speed is by using static invertors to supply them with variable-frequency, variable-voltage a.c. The ways in which this is done, and the results obtained, are described in this article View full abstract»

    There are many obvious applications of technology to the field of medicine, but it is the engineer who must be prepared to learn about the problems he is to tackle, to help the doctor define the problem sufficiently clearly and to produce the most effective solution, rather than one that just works View full abstract»
