BOOK NOTES
bakeries, breweries and dairies use germicidal lamps to decrease infection and spoilage.
Beef tenderizing plants estimate they increase their production 20 per cent by using germicidal lamps.
Photoelectric equipment is used to sort beans. The bad beans have dark spots which can be detected by the sorter.
Needless to sap, the equipment does not work on blackeyed peas. Electronic analog and digital computers are discussed briefly and examples of gas engine analyzers are described.
Records and diagrams of the electroencephalograph and the electrocardiograph illustrate medical instrumentation.
Paper mills require precise speed control at an adjustable speed, but many other industries having simpler speed control requirements also use electronic speed controls.
The author discusses electronic precipitation, the electron microscope, x-ray diffraction, automatic navigation equipment for aircraft, and high frequency heating.
This last application is a good example of the way electronics can increase production. Using high frequency heating equipment, a 30 lb. can of frozen cherries can be defrosted in 12 minutes instead of the 20 hours required by normal methods.
This application is a great help to food processing plants.
The numerous specific examples and the descriptive, rather than the mathematical approach make this book very entertaining and easy to read and if the reader desires more nformation on any specific application, he can refer to the bibliography at the end of each chapter.
