Plummer, chief engineer Edward Allen. Technical Research acting chief Wm. Boese. Lab Div. chief Edward Chapin. Demonstrations were successively Aug. 6-9 by ^ in Syracuse ; Hazeltine, Little Neck, L.I.; RCA, Princeton; Philco. Morrisville, Pa.
Main purpose of demonstrations was to enable National TV System Committee Panel 13 (standards), under Hazeltine's A.V. Loughren, to agree on which set of standards to field test from here on out — probably until year’s end.
Panel wound up in New York Aug. 10. agreed on "large fraction" of issues, according to Loughren. Recommendations will be submitted to NTSC's overall committee Aug. 15, and field testing during forthcoming several months will be based on them, if parent body is satisfied with them. [For panel members, see below.]
"There was agreement in principle." says Loughren, "with several specific 'numbers' recommended. We didn't pin everything down, but we're closer and closer to agreement. We did pretty well today. We'll let it soak a while."
Here are types of system variations shown;
(1) Color carrier at 3.58, 3.89 and 3.99 me.
(2) System with and without oscillating color sequence (OCS), also called "color phase alternation" (CPA) or "flip flop".
(3) Pictures with and without constant luminance factor.
Only RCA showed live pickups, rest using still pictures from flying-spot scanners. As test of color fidelity, resolution, etc., RCA compared televised color picture with slide projection of same scene, side-by-side. One observer scratched his head, blurted: "Which is which?"
Philco supplied weak-signal test in Morrisville, about 25 miles from its WPTZ transmitter, right on noisy U.S. Route 1. Then signal was attenuated to equivalent of 40-50 mile reception, and Philco v.p. David Smith concluded; "Stands up as well as black-and-white under adverse signal and interference conditions."
Schedule of further field tests will probably be issued soon. Zenith says it's prepared to cooperate by transmitting compatible signals over its experimental Channel 2 facilities in Chicago, first such telecast signals there. Zenith has also experimented with CBS-type transmissions.

Cost of compatible receivers would probably trouble FCC if system were put before it today. But most experts foresee drastic drop in matter of months, many agreeing that subtraction of 15-20 tubes from RCA's current 54-tube set is conceivable before year's end (Vol. 7;30).
Even more important, some say, are such critical techniques as color phase alternation, which permits far greater tolerances in construction. And there's little question cost of tri-color tube will plummet, just as tubes did for black-&white, when mass production becomes fact. Since manufacturers will want tri-color tubes — for CBS system, even if FCC again rejects compatible system — they're likely to invest in plants to make them.

Old song with new words: WCTU president Mrs. D. Leigh Colvin, at big temperance convention in Boston this week, said TV and radio are turning American parlors and kitchens into “beer bars”.
