Abstract

671,548. Laying pipes. MILLINGTON, J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 14, 1950 [Dec. 14, 1949], No. 32080/49. Class 99 (ii) A protective cowl 4 of frusto-conical shape is fitted ahead of a connection 3 joining two successive lengths of piping 1, 2 to provide a smooth transition between the piping and the leading end of the connection and to facilitate drawing the piping through an underground cavity as made by moleploughing. The cowl may be of metal and have a parallel-sided leading end 6.
