Show A NEW POWER transmission METHOD an illustrated booklet issued by W H dorman co ltd of stafford england and devoted to a description of what is claimed to be a new and original engineering science the transmission of power by waves through water was received through the mails on the first of the month the exhibit made certainly is one that will cause somewhat of a sensation in applied mechanics circles in this country in the booklet received are numerous illustrations showing the practical application of the new method of power transmission from the wave power generator down through the various characters of machinery to which the dormans bormans have harnessed it in the mining industry it is claimed to be particularly applicable to the operation of rock drills coal cutters pumps hoists haulage conveyors screens concentrators stamp batteries rock crushers etc illustrations of various machines utilizing the new power are shown and the statement is made that at the companas comp anys works in stafford practical demonstrations may be witnessed of the first of a series of practical appliances installed for the purpose during the next few months two chapters of the booklet are given over to a description of the theory of wave power transmission one popular and the other technical and by the inventor george con st antinesco the following paragraphs are culled from the non technical description of the new invention ven tion there are at present five methods in commercial use for the transmission of power namely steam direct mechanical electric compressed air and hydraulic wave transmission or sonic transmission are names used alternatively to describe a sixth method in which are employed wave motions or pulsations set up in an enclosed column of liquid the liquid usually water is contained in a pipe connecting the apparatus gullerat gel generating lerat the wave motions to the machinery which apples them to useful work although apparently similar to hydraulic transmission the underlying principle of wave is totally and absolutely distinct in hydraulics a continuous flow of liquid or motion of the liquid columns as a whole invariably occurs whereas in wave rave transmission there need be no direct or continuous flow the particles of the liquid mere ly pulsating backwards and forwards about abou a mean position water is compressible owing degree of its compressibility being very small compared to many materials in daily ual incompressible use the idea that water was waa came to be accepted even by engineers for ad a the first time in the history of mechanics of the vantage is taken in wave transmission elasticity of water and also of oil and obber ot fluids to transmit energy taking the simplest form of wave fitted fitted mission imagine two cylinders nue leot of side si plungers the cylinders on the under bya the plungers being connected together r if long pipe completely filled with water alid d UP P one of the plungers is moved rapidly stoe st down it will set up at each downward travel tra waves of compressed water which whick abot along the pipe at the speed of sound allergy their e feet per second will exert abig be on the plunger at the far end and it if va 00 suitably loaded a simple reciprocating 8 1510 tion will be produced in exact er with the of the first pi about abot but if you would know all a write for a copy of the booklet |
