In this paper is intended to study a three phase induction motor for railway applications. The steady state equivalent circuit is used to include and quantify all motor losses in the power balance.; The use of the proposed equivalent circuit, which allows a reliable assessment of the loss distribution and performance of this motor at different operating points, so comes as a particularly interesting tool to evaluate efficiency improvements, either in the motor design or in the materials selection.; Currently motor performance evaluation in railway applications is especially interesting, where the energy consumption has a significant economic and environmental impact., Postprint (author’s final draft)

La finalitat d’aquest projecte és la de dissenyar un sistema de tracció per a un sistema salva escales poc convencional. Aquest projecte està vinculat a un altre, el qual tracta del disseny d’unes escales articulades amb la capacitat de transformar-se en rampa. Per tant, l’objectiu d’aquest projecte és proporcionar un sistema de tracció i guia adequat per a aquest sistema d’escales articulades. El sistema de tracció escollit d’entre els diferents que n’hi ha per aquest tipus d’aplicacions, ha estat un sistema de pinyó-cremallera, mentre que el sistema de guia es basa en un sistema de rodets que corren per un carril. En aquest projecte s’han dissenyat i calculat els diferents components del sistema, tant de tracció com de guia. També es parla dels components electrònics que necessita un sistema com aquest, tot i que no s’aprofundeix en aquest tema, ja que el projecte és bàsicament mecànic.

Photograph of men working in a field. A steam plow and a horse team are visible on the left, and on the right men stand atop a large pile of what appears to be hay. **This photograph is part of a scrapbook created in 1906 and 1907 by railroad engineer C. J. French. Most of the photographs have little to no contextual information; all available information has been listed.

The clippings and correspondence in this scrapbook relate broadly to statewide operations of the Food Commission. The commission oversaw state policy relating to production, supply, and distribution control of food, ensuring that there were adequate supplies at reasonable and preventing speculation and hoarding during wartime. Topics include: local relations with the state; farm bureau labor rallies; disposition of poultry stock and eggs; labor shortages and state aid proposals; plans to "conscript" boys and girls in farm labor; and conservation efforts.
