There is no plot to speak of. The third man in the triangle unites the remaining two without opposition while the other characters in the play look on and beam...
Behind the line-covered viewing screen is a "grid" of fine parallel wires, one wire for each group of phosphor lines. At the narrow rear end of the tube is a single electron gun that shoots a slender beam of electrons through the wire grid at the viewing screen. As in all television tubes, the electron beam scans at a rapid rate, painting an ever-changing picture on the screen of phosphors...
...wire grid does this switching job. It is hooked up, through the proper electronic apparatus, to the signal that comes over the air. When the signal tells it that certain electrons represent red, the wires of the grid are charged with enough electrical potential to focus the electron beam onto a line of red phosphor. When "green" electrons come along, it switches them to green phosphor, etc. So, jumping from phosphor to phosphor, the electron beam paints its picture in full color...
...Douglas' inventors-of-necessity announced a new device which may well save hundreds of lives: a sea-rescue life raft which can be shot torpedo-like from a plane. On contact with the water, it inflates itself, starts its own outboard motor, can then be guided by radio beam from the mother plane to floating survivors. Now Douglas engineers are working on a brand-new project. Douglas Engineer Ed Heinemann, who thinks the aircraft bomb is the one piece of equipment which hasn't kept pace with aviation's modernization, is working on a new design. Says...
Returning Echoes. The heart of Ross's compact (150 Ib.) machine is a crystal of Rochelle salt† that converts electrical energy into pulses of "ultrasonic sound" (unlike radar, which uses radio frequencies). Focused into a narrow beam, the sound pulses are shot out through an underwater transmitter that can turn through 360°. Echoes from underwater objects come back to the transmitter and are displayed on one cathode-ray screen as part of a glowing map that measures distance and direction from the ship. Moving targets can be tracked across the scope as on an ordinary radar screen...
