| Thermostats by Roosevelt Griffiths 1934 157 pp 10/- (Chas: Griffin & Co: Ltd) The author of this book has surveyed the whole extensive field of temperature control. The very copious bibliographical references bear witness to the magnitude & value of the work the author has performed in presenting so much information on a specialised subject in such a handy form. The basic principles underlying the various methods of temperature control are clearly explained and anyone contemplating the use of thermostatic apparatus should find this very useful in the selection of a suitable type for any particular service. Apparatus for different types of laboratory work is described as well as representative examples of commercial instruments, most of which provide ingenious examples of the art of obtaining robustness without loss of sensitivity. Many practical hints are also given to assist makers and operators of apparatus to obtain the best results. The more recent types of apparatus employing photo-electric cells & thermionic valves lead the reader rather deeply into electrical science, but nevertheless, the descriptions are as clear & concise as it is possible to make them. It is interesting to note that this type of thermostatic control is said to be sensitive to 0.0006°C. It is unlikely that the automobile engineer as such will require such a high degree of sensitivity but as a general subject the control of temperature is of wide practical interest to him, since it has a direct bearing on such diverse subjects as heat treatment; circulating water heaters | ||
