X8070 X8230 With regard to the repeated failure of the above part, all the examples submitted appear to shew that the sliding joint B. does not work when the feed pipe is heating up, possibly due to the initial expansion of length A.{Mr Adams} and also to initial cross wind which may be in the same direction. [Stamp: RECEIVED 23 SEP 1927] When the pipe cools down it then withdraws a little from B. and takes up a fresh position for cross winding again when the pipe is re-heated. Finally the heater pipe assumes some shape as shewn by B the dotted lines, and throttles the flow of gas by the flattening of the section at the elbow. It appears to us that if the heater connection could be definitely fixed at the bottom end as well as the top, and the pipe made sufficiently flexible, the trouble could be overcome. The following alterations are therefore proposed for application to an existing chassis:- (1) | ||
