Years before television showed promise of becoming an industry, we had started our original research. Continuously since 1931, when the company was incorporated, we have had a staff of engineers at work on various phases of television research and we maintain well-equipped laboratories at this address. This research has intensively covered the field of both mechanical and electronic television. Numerous patents have been granted to this corporation— and numerous others are pending in the Patent Office. In recent years we have had complete camera chains in operation and, throughout the past year, have produced regular programs showing 441-line high definition pictures, using special transmitting equipment, designed and built by us, and specially designed receivers embodying our own inventions and development work. While the company is now prepared to supply any or all of the units listed above, a further announcement will be made in the near future, relating to A LINE of television receivers. When announced, these products will incorporate what we believe to be a very valuable improvement, developed by this corporation, to simplify operation and servicing and to make television receiver-performance even more reliable.
