'HE PHILADELPHIA INQUIRER, SUNDAY MORNING, APRIL 19. 1970 Lens Developed at Blue Bell Wins Academy Award An idea conceived on the i Corp. of Blue Bell and the Fire Control Development and Engineering Laboratories of the Frankford Arsenal. Its inventor, Juan de la Cierva, a former resident of Cuba who came to the Dela- Delaware River nine years ago led to an Academy Award this mont'n. The idea led to the invention of Dynalens." a device developed by the Dynascience '1 technical achievement at the Academy Awards presentation on April 7.

De la Cierva said the lens can be adapted to any optical instrument. It is now being used by still photographers, television and police cameramen to shoot pictures from moving gineering staff, led by Donald R. Furmamski and Kazmer S. Kazmerski. In 1S66 the Combat Development Command of the Army saw the lens demonstrated and realized its ability to stabilize high-powered optical devices in combat helicopters.

The lens was sent to Vietnam for testing. After testing, the arsenal was requested to send a quantity of the lenses to Vietnam. Deliveries were begun in May of last year and completed last March. The lens was also adapted for the motion picture industry. It was used in filming "Catch 22" and "The Riev-ers" leading to an Oscar for Old Ballroom Will Close For Those who like Plush Carpet ware Valley area after Castro took over, was trying to take movies of his two sons water skiing on the Delaware in 1S61.

He was having a problem keeping the camera focused on his sons because the boat in which he was riding was bouncing. He got the idea to make a lens that would stabilize an image on a vibrating platform. De la Cierv3, with Dr. Leonard Goland and Joseph B. Domagala, formed a company called Dynascience to develop the invention.

The Dynalens is a fluid prism in which a clear liquid in a bellows between two movable windows optically compensates for image motion. Electronic gyroscopes provide an inertially stabilized reference for sensing motion of the camera or instrument. When motion is sensed, ser-vomechanisms vary the window angle, compensating for the motion and stabilizing the image. Dynascience brought the Dynalens concept to the Army's attention in 1963. Its developers theorized that the device could be used for various military purposes, particularly surveillance and long- Mohawk' ys Brecken ridge f-Prr Y.

Wagner's Ballroom wras founded in 1893 by Prof. Harry D.

Wagner and his wife, Annie, as the Wagner Dancing Academy at 44 N. 4th st. Prof. Wagner specialized in instruction of the quadrille and the schottische and other line dances. He chalked pupils' heels so they would dance on the balls of their feet.

Beginners progressed from the Monday night line sessions to the Wednesday scholars' sessions and eventually to Saturday night "receptions." The academy prospered. There were no movies, radio or TV sets, record players or automobiles to distract the young, and ladies did not frequent saloons.

By RICHARD MURPHY Of The Inquirer Staff Wagner's one of the older public ballrooms is closing its doors at the end of the month. Joseph H. Smith, owner and direct descendant of Harry D. Wagner who stablished the original ballroom, 77 years ago, explained: "Wagner's, at its present location, does not live up to the Wagner standards of the past. "I hope to be able to open a new Wagner's in the Delaware Valley by next September," he said.

The ballroom, at 5810 Old York rd. since 1955, has been the scene of teenage record hops, adult dances and wedding receptions in recent years. The new owners, Applied Services, headed by Charles F. Taylor, said the ballroom would still be used for wedding receptions, and adult dances on Friday and Saturday nights. Taylor, who has managed lllltil 7-rOINT FROGRAM 1.
