George Westinghouse - Essay Example Although his influence on the modern civilization may be unnoticed by many the achievements and inventions associated with Westinghouse's name in some or other way surround us every day. The influence of George Westinghouse was decisive in improving the safety of the US railroad system, stimulation of the transportation industry growth, development of the modern electric distribution system and many other landmark inventions (Jonnes, 2003). The son of a machine shop owner, Westinghouse was the eighth of ten children. His father's machine shop manufactured a variety of industrial and agricultural machinery while Westinghouse Sr. himself was a talented inventor who registered at least seven patents. In 1860, at the age of fourteen Westinghouse Jr. started to work for his father at 50 cents an hour and got the first insights into machinery and metalworking. The Civil War interrupted the early start of his career as an inventor: George Westinghouse joined the Union army at the 15 and although his father forced him back in 1863 George finally received the consent of Westinghouse Sr. to be enlisted in the infantry. After several months Westinghouse Jr. became an engineer in the Union Navy (Dietrich, 2006). The Civil War was over when Westinghouse was only 19 and already at that age he created and patented his first invention, the rotary steam engine (Jones 2003a). After spending three months at tiny Union College, Westinghouse finished his formal education, returned to the machinery of his father's shop, and immediately produced a series of important inventions and engineering innovations. Thus, at age of twenty one Westinghouse invented the famous 'car replacer', a mechanical device to rerail derailed cars back onto the tracks and a mechanical 'frog' to switch trains onto of two tracks (ASME 1937). Although practical success of both these inventions Westinghouse did not gain much in terms of commercial success: his patent protection was not strong enough to prevent the railroads that adopted the replacer and frog from sidestepping his rights. However, Westinghouse considered the bitter experience and did not make the same mistake in the future. Prior to turning his attention to the new and exceptionally promising fields of activity Westinghouse had already become widely known as a successful mechanical engineer, inventor and entrepreneur. The number of patents issued to him during only five years between 1869 and 1873 exceeded 20, and one of them was for one of the most essential inventions of that epoch, namely the air brake (Jonnes 2003). During the next decade, the air brake gained overwhelming acceptance among the railroads but Westinghouse became interested in finding and exploiting natural gas. Although that part of Westinghouse's life is scarcely known and relatively insignificant considering his achievement in mechanical engineering and electricity, during only two years from 1884 to 1885 he applied for 28 patents. His gas inventions included the

Issues in Accounting Theory and Practice (Case Study National Case - 2

Issues in Accounting Theory and Practice ( National Greenhouse Accounts Factor) - Case Study Example The greenhouse gases include methane, carbon dioxide, specified hydrofluorocarbons, nitrous oxide, sulphur hexafluoride and specified perfluorocarbons. There are four methods used to conclude scope 1 emissions. The first one is fuel combustion that focuses on fuel combustion and the emissions it releases. There is ‘emissions of industrial processes’ that deals with greenhouse gases resulted from carbonates consumption and using fuels as carbon reductants or feedstock. It also focuses on the release of synthetic gases in certain cases. Another method used in scope 1 is fuels’ fugitive emissions, which focus on emissions from the removal, manufacturing and supply of fossil fuels. The fourth method is ‘waste emissions’ that deals with release of GHG from the decay of organic material in facilities handling wastewater. The first method is fuel combustion, and it is appropriate for Contex because the company deals with motor vehicles that release GHG throu gh use of fleet fuel. This is also because the most vital source is GHG emissions from the combustion of fuel that account for more than 60 per cent reported emissions. Scope 2 emissions are in most cases a type of indirect emission. The scope deals with activities that produce electricity, cooling, heating or steam that a facility consumes, but are not part of the facility. They take place mainly at electricity generators because of the consumption of electricity at a different facility. The emissions of scope 2 also come from electricity obtained from outside sources. The scope provides the factors of emissions through the electricity’s supplier or by using the NT’s emission factor. The generation of NT electricity largely represents a combination of the generation of diesel and natural gas, which is a logical equivalent for the fuel mix employed in outside electricity generation. The factors of emission for scope 2 show data depending on on-grid activity
