12 in the transmitter was common engine lubricating oil. Conclusion.—The transmitter dealt with above resolves in a satisfactory manner the problem of transmission of power at a torque ratio varying automatically and gradually within the whole range covered by the orthodox friction clutch and change-speed gear mechanism. Its application in an automobile in substitution for the orthodox clutch and gear mechanism results in an improvement of the performance of the vehicle in get-away, general acceleration, hill-climbing, drive in traffic and drive on the open road. The driver over long distances, in traffic and climbing sinuous hills is not worried by declutching and gear changing. The mechanical construction of the transmitter is in every way simple and sound; and compared with the orthodox clutch and gear mechanism, it is simpler and less costly, and its overall efficiency (as measured by petrol consumption on a long run) is appreciably greater. Its scope transcends the field of the automobile and should include vehicles of every kind driven by internal-combustion engines, both of the petrol and of the heavy-oil type. The transmitter has been evolved and worked out experimentally by Commendatore Piero Salerni, to whom the author wishes to express his thanks for his assent to the publication of the information given in this paper and of the drawings which accompany it. The author's thanks are also due to Mr. John Robson, M.I.Mech.E., and to the members of Comm. Salerni's staff, who made the apparatus from which the photographs reproduced in Figs. 21, 22 and 23 were obtained and also assisted in the laboratory tests.
