or semi lustrous however it is also possible to improve the brightness of the deposit by adding known brightening agents such as those disclosed in any of the prior art patents listed earlier the resultant plating bath will then have all of the desirable characteristics of a bright or semi bright deposit the surface active agents can be rendered more solution soluble by techniques generally known in the art such solution soluble derivatives of the desirable surface active agents can be made e g by sulfating sulfonating phosphating phosphonating carboxylating etc provided the derivative does not impair the suitability of the material for purposes of this invention stated previously there are a wide variety of high speed electroplating equipment commercially available today one typical apparatus is disclosed in u s pat no 3 819 502 to meuldjik while others are disclosed in articles entitled 34 high speed electrogalvanizing line with insoluble anode at kimitsu works of nippon steel corporation 34 by m morimoto et al 34 swim plating as a continuous process 34 by j j miles et al and 34 continuous plating of copper nickel and chromium on wide steel strip for decorative and function applications 34 by h wettner a high speed machine for controlled depth electroplating is disclosed in an article entitled 34 how to save gold with selective deposits 34 by c d eidschun each of these papers was presented at the american electroplater 39 s society 39 s second continuous plating seminar chicago ill jan 24 26 1977 it must be emphasized that these high speed electroplating units are merely illustrative and fall within the general description given in this application those skilled in the art are aware of a wide.
