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...
Electron Switching. The trick in color television is to make the electrons that represent red, for example, hit the phosphor that glows in red. In the Lawrence tube, the 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...
...always more pleasant to boost than to knock, and it would be nice to be able to say that the performance against Springfield "marked a definite turn in Crimson grid fortunes." Nice, perhaps, but not true, for the Harvard team still shows many weaknesses, some of which may be erased, in time...
...physical Yale is plunked incongruously down in the heart of a prosaic, overgrown town-a neo-Gothic citadel besieged by a grid of Main Streets. Neon signs blink into its leaded windows; drugstores, shoe stores and tailor shops challenge its ivy-covered walls. The worlds of Samuel and Howard Johnson are but a step apart...
