...ordinary black & white camera, has a single Image Orthicon "seeing" tube. In front of it is a spinning disc with segments of blue, green and red transparent plastic. When a blue segment is in front of the tube, the camera sees only the blue light coming from the scene being televised. When the disc has turned a little, putting a red segment in front of the tube, the camera sees only the scene's red light. Next, it sees green through a green segment of the disc...
...Dots. RCA's system, called "dot interlacing," is entirely electronic, needs no spinning disc. In the transmitting camera are three tubes. In front of them is a system of "dichroic mirrors" (see below) which allow each tube to "see" in one color only. All three tubes scan the scene continuously, but an electronic switching device, turning their signals on & off 11.4 million times a second, allows each tube to transmit over the telecasting station only one-third of the time. In this way the "video signals" from all three tubes are strung together like trains made...
...color. Each little impulse (the colored freight cars) arriving over the beam is electronically switched to the properly colored tube. They arrive so fast that each tube-face is covered 15 times a second with a pattern of tiny dots corresponding to the blues, reds and greens in the scene being televised. The more red there is in a part of the scene (e.g., a red dress), the brighter the red dots on the corresponding part of the red tube...
Another fact is that RCA's system still does not work well. It has rarely been shown to the public, and does not impress laymen. Different sets show the same scene in different colors. The colors are not at all faithful; they often change suddenly and erratically. Dr. Elmer W. Engstrom, research chief of RCA, admits that the system is still in the laboratory stage. But RCA-men add that the CBS color system has reached its limit: it has no "room for growth...
Dean Bender commented that the College does not interfere with the membership policy of undergraduate clubs except to specify that they must be Harvard men. He noted that concern with social clubs is unnecessary because of the small part they play in the College scene...
