Calculation and Design of Electrical Apparatus. By \V. Wilson,
M.Sc, B.E., M.I.E.E., M.Amer.I.E.E.
(Pitman. 10s. Cd. Pp. 214.)
This is a lucid treatment of the principles upon which the design of
switchgear is based, and throughout the work the student's viewpoint
is fully considered. The opening chapters deal with fundamental calculations of a simple nature, the heating effect of an electric current applied
to fuses, busbars, and insulation, and close with a useful treatise on
electromagnetic forces with reference to switch blades and busbars.
Resistances for regulators, instruments, and motor starters are considered next, followed by a chapter dealing with system short-circuit kVA
capacities and the rating of oil circuit breakers. The design of electromagnets, solenoids, and coils is dealt with in a practical manner, leaving
no doubt in the reader's mind as to the correct method of procedure.
Calculations of busbars and heavy conductors, with reference to skin
and proximity effects and resultant temperature rise, precede a chapter
dealing with overhead lines, cables, condenser bushings, and choke coils.
The last chapter should be found useful to all students as it contains
the principles of vectors and vector algebra, symmetrical components, and
their application to determine the distribution of current in networks
under fault conditions.
A list of references to current literature is given at the end of each
chapter, whilst another commendable feature of the book is the complete
set of tables of relevant data. This book will prove an invaluable acquisition to the student's library.
Training in Foremanship and Management. By James J. Gillespie,
(Pitman. 7s. 6d. Pp. 163.)
This book is a good outline of the fundamental knowledge±uired by
any man who hopes to achieve or has already attained a position in control
of manufacture.
The first part comprises a survey of works organization, with chapters
devoted to the various functional activities, such as planning, progressing,
time-study, wage payment, and costing. One particularly good chapter
describes how to analyse factory efficiency.
The unusual merit of the book, however, lies in the second part, under
the heading " Management Theory." Management, as those who have
studied and experienced it will testify, consists not in a huge store of
detailed knowledge, but in an intelligent, reasoned, decisive approach and
solution to problems and duties. The development of managerial ability
is, therefore, largely a matter of personal development. This fact is
being increasingly recognized. Mr. Gillespie's book, with its special
chapters on personal psychology and the development of executive ability,
and social psychology and the control of labour, is not only informative
but stimulating.
