Richardson's handbook of projection (1927)

HANDBOOK OF PROJECTION FOR How should tables 3, 4 and 5 be used in conjunction with the limiting value suggested by previous questions ? 492c to 492e How do surfaces A, B, C, D, E, F, G, and H show the enormous difference in "fade-away" in different surfaces and how should such charts be read? 492e Is kalsomine an excellent diffusing surface (also see page 228, first volume) 492e May there be a literally enormous difference in commercial screen surfaces in the matter of reflection power at straight-in-front and at various angles to the surface ? , 492f Speed Indicators Powers Speed Indicator 703 Transformers Is it possible to use a transformer on direct current? 596 What is the general plan of construction of a transformer insofar as has to do with its electrical action? ... 596 to 601 Upon what is the electrical action of transformers based? 596 Describe, in a general way, the action of a transformer 596, 597 In what way is the action of transformers in generating or "inducing" current directly opposite to dynamo armature action ? 597 What is the secondary current of a transformer termed ? 597 In what way and for what reason is the action of transformers automatic in increasing or decreasing the amount of secondary output ? 597 In what manner are the two magnetic fields of a transformer automatically kept in exact balance? 597, 598 Types of Transformer Into what two types are transformers divided? Describe each type 598 Efficiency About what is the efficiency of a well designed and constructed transformer and in what way are the losses incurred? 599 Transformer Core Of what does the core of a well designed transformer consist ? , 599 xiv
