"Companion volume to 'Dynamos and motors." In the preparation of these two volumes especial attention has been given to the physical principles which underlie operating engineering but little attention has been given to the principles of design.

Page 133 - The incandescent lamp consists of a carbon filament enclosed in a glass bulb. In order to produce light, the filament must be raised to a very high heat. If this were done in the atmosphere, the carbon would be consumed. For this reason, the filament is enclosed in a glass bulb from which the air has been withdrawn. At the small end of the bulb, two pieces of platinum wire are sealed in the glass, to the inner ends of which are attached the two ends of the carbon filament, and to the outer ends two...

In the great majority of cases no material is actually deposited at either electrode in the electrolytic cell, but chemical action is always produced in the immediate neighborhood of the electrodes, and the amount of chemical action which takes place in a given time due to the flow of a given current through the cell can be calculated from very simple data. A statement of the method employed in this...
Page 262 - Fig. 3 yield, in the two is the same), whereas two mechanical elements have the same stress when they are in series; to have the same strain or yield, two mechanical elements must be in parallel. Thus Fig. 3 shows a column of steel and a column of rubber equally compressed between two bars A and B (the steel and rubber columns are in parallel); the easily yielding rubber (high inductivity) supports a small part of the compressing Fig.
