    The paper deals mainly with the development of the BBC 625-line u.h.f. television services and the introduction of colour, but reference is made, where appropriate, to other important developments, both at home and abroad. It also looks at the future and mentions some of the new techniques likely to be exploited to reduce engineering costs, increase reliability, improve performance and extend the ...

    After an historical sketch of the development of the electron microscope, the main features of the various types of existing instruments are described. Attention is confined to those which are commercially available, and experimental models are discussed only when they embody significant new ideas. The emphasis is on design and operation. Applications are included only incidentally, and specimen p... View full abstract»

    The paper presents a survey of miniature-circuit-breaker (m.c.b.) design and practice. After tracing the origins of m.c.b. technology in Europe and the USA, it examines their influence on the British concept, with particular reference to the degree of overload and short-circuit protection provided. To ensure the successful application of m.c.b.s, it is essential that they be properly integrated in... View full abstract»

    The growing importance of portable and transportable power sources is emphasised. This is to some extent associated with the growth in the use of cordless appliances of all types, but the range of applications storage batteries, the reliability of which has been well established, is also steadily expanding. Claims have been made that there are now 95 distinct uses for secondary cells and batteries... View full abstract»
