 Boeing Engineering Company with headquarters at Seattle, Washing ton, and we began to go to work in earnest in the development of the cycloidal propulsion system. Later MT. Boeing dropped and was quite broke
 Time passed, and finally was able to obtain patents in every country in the world In 1924 I went to Germany, to Berlin to push 1 the patents through the Berlin Pat ent Office. I tried to interest the United States Army and our Navy. I experienced political hard luck and it seemed like I would in evitably approach the wrong peo- plel in the various government :, bureaus.
 Austrians Wideawake Finally the Austrian firm of ] voith- Schneider, realizing the pos abilities of this system, spent mill lions of marks to develop it and with great success"
 At this juncture of the interview Professor Kristen, pointed out that he had maintained his American patents on the new invention and that later Germany had tried to enter the American market with their propellers and found that they were in conflict with my patent rights.
 Later" he continued, Germany asked me to sell out my patent rights. Both Boeing and refused but made them compromise and offered them (this was during 1934- l 35) an option to manufacture the prolellers in America provided they pay up royalties
 The speaker pointed out that shortly before the war, the Ham, burg American Line launched g. O00- passenger liner, using the new type of propeller.
 Used On E-Boats Not very many weeks ago." said l the inventor. q found out through various channels that the E-boats used by Germany in the English Channel were using the same type of propeller. I recently saw the photograph of a large German cruiser which was also equipped with the same type"
 He asserted that tat the present time we are intensely active to focus | the attention of the American Gov ! ernment in the most significant development which undoubtedly will start a new era in marine and aerial navigation"
 Two weeks ago, Professor Kristen visited Washington and interviewed the technical staff of the U. s. Army l, in order to furnish drawings and designs for the first cyclodial ship in America. Success at last! Now for ati explanation of "cy- cloidal propulsion"
 This new invention = a propeller "that is not screw propeller and which does not operate on hori- zontal but on a vertical shaft. What are the advantages of this newly developed propeller?s There is no vibration of the ship; consequently her presence cannot be detected by the delicate listening devices of a submarine. Further, 1t stabilizes the ship against rolling. The rudder and the complicated machinery is completely eliminated. No Signals The engine and the propeller op- crate at constant speed at all times, consequently no signals are required to the engine room. The ship is instantly controlled in all of its movements from the bridge. From full power ahead to full power astern" is accomplished in two sec onds time, and it has been found that ship thus equipped may be stopped from full speed in half of its length.
 It has been found that the ef- ficiency of the propulsion system is far superior to that of the screw propeller, and it is estimated that on marine installations 30 per cent of the fuel oil may be saved for the same performance.
 The Government, said Prof Kir- sten, lis favorably impressed with the proposals. Blue prints of the new system have been submitted for approval and we are awaiting final orders for production" The inventor will leave Seattle early next week to consult with government officials in WaShfnotor,
