SOUND REPRODUCTION.

WELLINGTON RESIDENT’S

INVENTION

(Australian Press Association —United Service). LONDON, Sept. 3. Mr John Maxwell, chairman of British International Pictures, Limited, lias acquired an interest in Rod’s Patent, Limited, New Zealand—a new process for the reproduction of sound — and is forming a company with European capital of £250,000 to purchase the European rights.

Rod’s Patent is tho invention o£ a young Wellington resident, Mr A. E. Rod, of Day’s' Bay, states a Wellington exchange. Mr Rod has been working on his idea tor the last ten years. He began by inventing a new type of gramophone, but that did not come up to expectations. Then lie delved into tho mysteries of radio, and sound, reproduction generally, always with his basic theory at the back of his mind—a theory fconstituting a radical departure from accepted principles which govern sound reception through the telephone, the gramophone and the radio loudspeakers. The result was bis present invention, which lie took with him to Britain and America some two or three months ago. The impression produced upon the listener is of tho presence in the room of the actual voice or instrument, whether it came from the local radio station or Sydney. Tho difference between the tone and that received through the present types of receivers is something like the difference between tlie roundness of a stereoscopic photograph and a flat picture, and it is a striking and arresting difference. The patent can be used in~a variety of ways, for telephones, musical instruments, as well as for radio reception. A local company was formed to finance the sale of the patent abroad, and the cable message this morning appears to indicate that the venture has attracted favourable attention in England where a successful demonstration of tho patent was recently given.
