1,203,136. Water supply by pipes. A. P. PEDRICK. 23 Feb., 1970, No. 15589/68. Heading E1X. [Also in Division F2] In an arrangement similar to that claimed in Specification 1,047,735 for transmitting snowballs through a pipe line, which might tend to break the pipe. The input end of the line is supplied through a number of branch pipe lines each fed by a separate ball making machine to provide constant total mass flow, and each branch line is provided with a smooth surface and internally heated, preferably by electricity, to give a water film on the surface and thereby minimise frictional drag forces arising from glacial movement which might tend to break the pipe.
