CONVERSION MOUNTING - LARGER DAMPER DISCS. x7005 Please find herewith LeC. 2934. shewing some damper discs of 50% larger area. We have designed these in response to a report from RM.{William Robotham - Chief Engineer} (HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}4/AD11831.) that the high unit pressure on the present dampers being tested in France has set up a knock. It is desired to produce some of these larger dampers and send them out to GWH.{George W. Hancock - Head Chateauroux} at the earliest possible moment. E.{Mr Elliott - Chief Engineer} | ||
