...fire X rays at so big a circle when the target is a rectangle only 1 in. by 1½ in. To keep the X rays from fanning out, they must be "collimated"-made to follow parallel paths. In their machine, the Nashville dentists use a stainless-steel plate with a rectangular window to accomplish collimation; they also use much more shielding and a steel bracket to hold the film just where it ought to be, without subjecting the patient's hand to radiation. The result, according to PHS tests, is a radiation dose delivered to the skin only...
...power stream flows out entirely through the other arm of the Y. A puff of the other control jet reverses the process, just as a small voltage change on the grid of a vacuum tube can control a relatively heavy flow of current through the tube's plate circuit. Like a vacuum tube, the fluidic circuit can thus be used as a switch to turn on or shut off a supply of power...
Assuming that a life-sized tornado could also be stopped by equalizing the charge on adjacent regions in storm clouds, Rossow proposes a novel experiment. Fine wire could be wound into a projectile and fired through tornado-spawning clouds. After the projectile leaves the cannon, a parachute-like plate attached to one end of the wire would pop open. It would pull on the wire, causing it to unravel from the speeding projectile...
Before the OSS sent her to Asia, Julia was in Washington, D.C., where she struggled valiantly with a hot plate, only succeeded in "splashing chicken fat all over the walls." Back home after the war, she enrolled in a Los Angeles cooking school to prepare for her marriage-with disastrous results: her bearnaise sauce congealed because she used lard instead of butter; her calves' brains in red wine fell apart; her well-larded wild duck set the oven on fire-she had completely forgotten to put it in a pan. Says Husband Paul gallantly: "I was willing...
...grow but at a slower rate, and modernization of plants has raised steel capacity beyond actual needs. Western European steel plants, which normally work at 90% of cinacity, have had to cut back to 78% of capacity for the second half of 1966, and the price of steel plate has dropped from $107 a ton two years ago to $99 today...
