1,030,819. Liquid resistors. N. R. WALLIS. Feb. 19, 1965 [Sept. 26, 1964; Dec. 5, 1964], Nos. 39302/64 and 49577/64. Heading H1S. [Also in Division H2] The connection between an electrolytic paint - spraying apparatus and a high voltage generator comprises a liquid resistor with a value of 100 megohms, the resistor having a flexible nylon or polyethylene tube 41 filled with a liquid or gel, preferably glycerine to which has been added water and copper sulphate, each terminal end including a tapered plug 42 inserted into the bore of the tube 41 by means of a selftapping threaded portion 43. The plug is of brass and is provided with an electrode 46 of the same metal of the salt dissolved in the liquid, viz. copper in the case of copper sulphate. Each end of the flexible tube 41 is covered by a length of rigid tube 51 consisting of, for example, polyvinyl chloride. |
