Saigon's most pressing concern is the area that includes the capital itself. In eight surrounding provinces, the Communists have tightened what American advisers call a "doughnut" around the capital. To the south, between Saigon and the Mekong Delta, the Viet Cong are so strong that more than 50% of the population there is estimated to be under varying degrees of Communist control. To the north, the Viet Cong are steadily increasing their pressure, last week hit four government battalions in three days. The guerrillas operate right...
Conquering the Virgin. The reinforcements will be partly concentrated on the hardening "doughnut" around Saigon but will also make possible more military advisers throughout the country-currently pegged at two U.S. officers and one enlisted man for each government battalion. The locals manning isolated outposts who comprise half the government's 400,000-man military force, will also get more U.S. help...
...standing next to the two Nigerians during their confrontation with Hayes Bick. The students took their time deciding they wanted some coffee and a doughnut. The man behind the counter waited.

The man wiped the tray with a paper napkin. The pipe smoker loudly protested that wiping a tray did not make it clean. The man removed the tray and put another one in front of the students...
...principle works in practice. Magneform - a tool little larger than a home washing machine and using no more current than an electric range - has no moving parts at all. Its essential part is a coil of heavy wire that can take var ious shapes, including a cylinder, a doughnut or a flat disk. When a massive electric current from a capacitor is shot suddenly through a coil, it creates an intense magnetic field in the space around it. If a piece of metal is near by, the magnetism starts currents flowing in the metal. These currents are surrounded by their...
...different coils do different jobs. When the end of a metal tube is inserted into the doughnut-shaped coil, it can be shrunk tightly around any insert such as a plug or a threaded fitting. To expand a metal tube, a cylindrical coil is pushed inside it. A flick of the switch, and the tube expands to bind itself solidly to whatever surrounds it. To stamp a flat piece of metal with a pattern, a trademark of elaborate lettering, the metal is placed between a flat coil and a die. When the coil is activated, the opposing magnetic field...
