The appearance of electrochemical batteries provided an impetus in research into practical applications of electric current. The first prototype of electric telegraph appeared in 1804. In 1838, Jacobi experimented with a battery-driven motorboat on the Neva River not far from St. Petersburg. These achievements led to rapid development of the theory and practice of electrical engineering, and the seventh decade of that century saw the appearance of a revolutionary new power source the electromagnetic generator (Werner von Siemens, 1866), which soon surpassed their predecessors in both electrical and economic parameters.

From 1904 to 1910 C. W. Bailee (7, 18, 55) analyzed many niobium and tantalum compounds and determined the atomic weights of both metals. In 1906 Werner von Bolton of the Siemens Halske Company... [Pg.344]

Two new elements of the manganese group, numbers 43 (eka-manganese) and 75 (dwi-manganese), were announced in June, 1925, by the German chemists Dr. Walter Noddack and Dr. Ida Tacke of the Physico-Technical Testing Office in Berlin and Dr. Otto Berg of the Werner-Siemens Laboratory.

Ozone as the more reactive elemental modification of oxygen was discovered by Ch. F. Sehonbein in 1840 who named it after the intense odour. The generation of ozone in reasonable amounts was made possible in 1857 by Werner von Siemens who constructed an electrical discharge apparatus. The discovery and development of the ozonolysis reagents followed in 1903 by C. B. Harries who applied it to the selective oxidation of olefins. [Pg.7]

Plante s seminal work on the electrochemical power storage was taking place at about the same time Werner von Siemens (1857) was producing a practical electromechanical generator or dynamo and thus the electrical industry was bom. [Pg.547]

In 1906 Werner von Bolton at Siemens Halske in Germany manufactured niobium by the aluminothermic method and purified it by repeated re-melting in a vacuum furnace. [Pg.556]

In Germany the first lead cables were provided by Werner Siemens ) as long ago as 1851 for the fire-alarm network of the City of... [Pg.15]

Berlin. These cables consisted of a gutta-percha covered conductor threaded into a lead pipe, the diameter of which was subsequently reduced by cold drawing until the pipe fitted tightly around the cable core. Three decades had to pass until in 1882 there was used a press, constructed by Werner von Siemens, on which the lead sheath was directly extruded on to the cable core. [Pg.16]
