| Y2677. By/NHW. from E.{Mr Elliott - Chief Engineer} c. By.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} E1/M.1.7.30. X.4660 X.2677 STROMBERG CARBURETTER PATENTS. On the down draught Stromberg carburetter the vacuum of the induction pipe is used for operating the accelerating petrol pump. An illustration of this carburetter is shewn in "Automotive Industries" of Sep.14 1929. We should be glad if you would make a search through the patent records to see if anybody else uses the induction pipe depression for this purpose. We expect that Strombergs have patented this method of operation but we want to know if their patent is good. E.{Mr Elliott - Chief Engineer} [Text in left margin, sideways]: ENS | ||
