RCA AND OTHERS SUED BY DUBILIER CONDENSER
Patent suits were filed in the Federal District Court at Wilmington, Del. , Wednesday by the Dubilier Condenser Corporation against the Radio Corporation of America, the National Union Radio Co. , and the Perryman Electrical Co. , Inc. , according to the Associated Press.
The three concerns are charged with infringement of a patent for improvement to electron tube apparatus. The apparatus is used to increase the efficiency of radio tubes which are used in sets operated by house current.

PERMIT FOR IMPROVED TELEVISION STATION ASKED
Authorization to construct a new experimental television station at Portland, Me. , for the purpose of testing new apparatus devised by the RCA-Victor Company was asked this week of the Federal Radio Commission through C. C. Kolster, Radio Supervisor, at Boston. The application was filed by the Congress Square Hotel Company, which operates WCSH at Portland.
The station would be established at a cost of approximately $200,000 and would conduct experiments in the ultra-high frequencies, the request, filed by William L. Foss, Chief Engineer of the appli¬ cant, stated. It would further provide a service in northern New England that does not now exist.
The application brings out that images of vastly improved definition and quality are possible with the new RCA apparatus, which never has been publicly exhibited. Whereas the recognized standard transmission today constitutes pictures of 60 lines, with 20 frames per second, the application states that the apparatus to be used would be capable of pictures of 60, 120 and 240 lines, with 18, 22, 28 and 30 exposures per second.
The application is said to be the first of a series of three to be filed by the Rines interests for New England. This company, in addition to its ownership of Station WCSH, has construc¬ tion permits for two additional broadcasting stations, one at Manchester, N. H. , and the other at Augusta, Me. , for which a removal application to Lewiston, Me. , now is pending.
The application requests power from 500 to 5,000 watts for the experiments. The frequencies requested are 43000 to 46000 kilo¬ cycles, 48500 to 50300 kilocycles and 60000 to 80000 kilocycles. The station would be operated about four hours daily.
