Tiny Gyroscopes. The key part of the "Dynalens" system is an adjustable prism that is placed in front of the lens. It consists of two circular glass disks, one at each end of a short cylinder formed by a flexible bellows. The inside of the cylinder is filled with a clear liquid, usually alcohol. By tilting one or both of the glass plates, the cylinder can be made wedge-shaped, like a prism. Light beams entering the glass plate at one end of the prism are thus bent and emerge from the other plate at a different angle...
When an optical instrument is shaken or moved, two tiny gyroscopes in the Dynalens collar sense the motion and send signals that control miniature electric motors connected to the glass plates at each end of the prism. The motors, which respond almost instantaneously to movements of the optical instrument, tilt the plates to change the shape of the prism, thus bending the incoming light beams just enough to compensate for the motion. The result is a clear and remarkably steady image...
...high sausage-shaped balloon enfolding plain air, for instance, was the dominant feature of the landscape at West Germany's Kassel Documenta last summer. He has constructed dozens of storefronts with empty display windows. They leave the viewer with his nose pressed against the glass-foolishly aware that he is observing the presence of pure nothingness...
Faulty Caisson. Laced by giant cross girders and faced with bronze-tinted glass and ebony-colored aluminum, the John Hancock structure tapers dramatically upward in the Chicago skyline like a flat-topped oil derrick. The first 43 floors are designed largely for commercial use. There will be five floors for a bank, a brokerage office and retail shops. Above that come seven floors of parking space-enough for 1,200 autos-and then 28 floors of office space, which will add at least 7% to Chicago's supply. There is a 44th-floor "sky lobby," consisting of a barber...
...weeks the walls of Paris and the sides of its ancient buses had been plastered with huge red posters bearing the reassuring message: "Saint-Gobain . . . a trustworthy trademark." Day after day, France's most aristocratic company, which was set up in 1665 by Louis XIV to make the glass for Versailles, blared its virtues in unheard-of fashion for French corporations-double-truck newspaper ads, regular radio and television appearances. Since Christmas, France has experienced what in the business world is something like the student-worker upheaval of last May and June. Compagnie de Saint-Gobain, Europe...
