Not illustrated. 1915 edition. Excerpt: ...one for the French air craft industry. While the exports to foreign countries, particularly to Russia and Great Britain, showed a slight decrease as compared with the previous year, the large government orders for aeroplanes and hydroaeroplanes have kept the factories running at their full capacity ever since the outbreak of the war. There were 177 aeroplanes, valued at $1,731,000, exported in 1914, against 271, valued at $1,942,000, in 1913. There were also 15 hydroaeroplanes, valued at $167,000, exported, as compared with 15, valued at $154,000, in 1913.--U. S. Com merce Reports. IF # John Fraser, formerly superintendent of the De La.

The oscillating magneto is agenerator in which the movable element or rotor is moved, with respect to the stator, through a fractional part of a revolution by the force exerted by springs during their recoil. The speed at which the rotor oscillates through this arc is relatively high and the arc of oscillation is relatively short, so that the design of an efficient oscillating magneto requires &.l8Ctl'iC3.l considerations quite different from those essential to the ordinary rotary type of magneto. It is the purpose of this paper to analyze and discuss the oscillating mechanism, to discuss the electrical phenomena occurring in the ignition generator, especially the transients that occur during sparking. The necessary electro-magnetic conditions for an effectual relational between the mechanical input and the electrical output are pointed out. The application of this form of magneto and its principal advantages will also be...
