...Control a laser beam with a system of gas-filled tubes and mirrors...
...M.I.T. and Johns Hopkins, the only two academic entries on an otherwise corporation list, are among the top 100 because both institutions are involved in expensive applied research in such fields as Over-the-horizon radar, electromagnetic applications and military uses for the laser beam. M.I.T.'s contracts last year totaled $94.9 million, while Hopkins' amounted to $71.1 million...
When the roof of a Fort Worth building began to cave in beneath his feet, the first thing Building Wrecker Walter J. Piper did was to throw away his crow bar. The act came within a quarter of an inch of taking his life. Sliding down a beam as the roof fell, Piper, 69, plummeted onto the 5-ft.-long, l-in.-thick tool, which had lodged point up in a pile of debris. The crowbar rammed through Piper's scrotum, smashed his pelvis, punctured his intestines, stomach, diaphragm and a lung before stopping within a quarter...
Schumacher obtains his electron projectiles by boiling them off a heated metal cathode. High-power electrical fields focus them into a narrow beam and boost them up to tremendous speeds - in much the same manner as electron beams are generated inside a TV picture tube. But Schumacher's gun has a special capability: its electron beam maintains its focus and power for a short distance after it squirts out of the gun barrel and into the atmosphere. In earlier experimental cutters the beam lost its power almost immediately in collisions with air molecules; the target material...
...chambers from which pumps are continuously evacuating the air. By simply blowing a steady stream of inert gas past the final hole-the muzzle of the gun - he stops dirt and debris from being sucked back into the vacuum. No wider than a sixteenth of an inch, the electron beam, says Schumacher, can cut iron bars, granite blocks or slabs of concrete. Only requirement is that the gun be kept virtually on top of its target. From a half inch out, it can burrow up to four inches into the toughest stone in less than a minute. It also works...
