摘要:
The first permanent broad-band super-frequency system to be operated in Great Britain was put into public service in March, 1952, to relay television programmes between Manchester and Kirk o'Shotts and so extend the B.B.C. television service to Scotland. The paper discusses the considerations which led to the adoption of a 4 000-Mc/s radio-relay system for this service, and gives a detailed description of the design and performance of the equipment. The conclusions which have been drawn from some fifteen months of daily operation are given.

摘要:
Some accounts of damage to lead-sheathed cables by rodents and insects have been reviewed and an attempt has been made to summarize the grounds on which the various authorities appear to have based their conclusions.Damage by rodents, and damage by insects to cables above ground, is probably related to the presence of organic matter either as extraneous debris or as an essential component of the cable serving or associated structures.The problem of preventing damage by termites to buried cables is complex. Several suggestions are made with reference to the nature of the problem and the information required in order to find a satisfactory answer.

摘要:
A form of vector presentation is described in which one vector is used as reference and displayed as a radial line from the centre of the display-tube screen. Other vectors are represented as dots which mark their extremities. Each vector is replotted during each cycle. This enables locus diagrams to be observed and recorded, such diagrams including a time scale. Some examples of the application of the apparatus to the study of electrical machinery are included.
