Telegraphing

Vertica.1 Axia.1 Deposition. The vertical axial deposition (VAD) process (18) was developed by a consortium of Japanese cable manufacturers and Nippon Telephone and Telegraph (NTT). This process also forms a cylindrical soot form. However, deposition is achieved end-on without use of a mandrel and subsequent formation of a central hole. Both the core and cladding are deposited simultaneously using more than one torch (Fig. 12).

II should noi be overlooked that platinum has played a crucial role in ihe development of many branches of science even though the amounts of metal involved may have been small. Reliable Pt crucibles were vital in classical analysis on which the foundations of chemistry were laid. It was also widely used in the development of the electric telegraph, incandescent lamps, and thermionic valves.

With the discoveiy of electricity, the evolution of communications occurred at a rapid rate. Smoke signals that were used for hundreds of years to convey information at a word or two per minute were first replaced by the use of copper-based conductors, such as the telegraph, that transmitted twenty to forty words per minute. By the end of the twentieth century, lasers with fiber optic wires transmitted an entire book around the world in under a second. 

In addition to the telegraph, the invention of electricity resulted in the development of other communications systems that paved the way for the modern communications infrastructure. The telegraph was followed by the laying of the transatlantic cable (18.S8), the invention of the telephone (1876), Marconi s wireless telegraph (1897), television (1927), and satellite communications (1957). Although early implementation of each technology was restricted to a minimum level of practical communication, each technology eventually evolved into a mass market for use by businesses and residential customers.
