Brig rolex swiss replicas . Gen. David Sarnoff, swiss replica rolex watch president of RCA, has pronounced this new achievement of his engineers, "one from the greatest actions inside the complete of radio science." Simultaneously he cautions against public expectation of complete colour tv quite quickly. It will be four years just before it can be put into full industrial use, he says. Though the significant scientific problems have already been solved, it can require that substantially time to develop and create all the gear required for full scale operation.

The most quick benefit of your new invention is this: present-day black and white equipment may be developed and expanded totally with out fear of obsolescence.

The moving image, studio play, or what ever image is to be transmitted, is broken up into these three components by a technique of color-selecting mirrors and photocells that convert it to electric impulses.

In the receiver, 3 kinescope tubes pick up the three individual color signals, rolex watch replicas all of which arrive on time, completely synchronized. Cathode ray projection tubes project all of them around the getting screen by means of 3 lenses, forming the full image.
