THE BATTALION Wednesday, August 25, 1971 College Station, Texas Page 7 1 NASA research helps Accurate home, industry digital clocks now feasible Accurate digital clocks for use in homes and industry can now be produced more economically and in quantity as the result of technology developed by the Na tional Aeronautics and Space Ad ministration. Officials of Ropat-Caslon Inc., a clock manufacturer, found a solution to their needs in a NASA “Tech Brief” issued in 196S, describing a precision stepping drive mechanism de signed to position scale models of spacecraft accurately about a horizontal axis, in wind tunnels and other testing situations. The device replaces gears and other continuous drive mechan isms which proved less accurate for operating electric-powered clocks. When coupled with a high-accuracy oscillator, the step ping drive provides accurate time by advancing a digital clock in increments of one second, one minute, or any interval required. In its digital clock application, the plastic stepping drive serves as an “indexer”, coupled through large scale integrated electronic circuits with a precision oscil lator, such as a quartz crystal or tuning fork. After a predetermined num ber of oscillations of this control device a signal is initiated, suc cessively advancing the stepping drive, with the oscillator insur ing accuracy through precise control of the stepping interval. This procedure enables the clock to present a succession of cards in a viewing window or aperture, a new card with each step, indicating the time as 11:45, then 11:46, etc. Such clocks can be built to read out the time digi tally in minute or second incre ments, depending on the degree of precision required. One of the digital clock’s most familiar applications is in clock radios. Digital clocks have found a wide application as consumer items in homes and as more so phisticated timing devices in in dustry. The new, more accurate step ping drive models are just begin ning to enter the commercial market, Dr. William D. Clark, president of the firm said. The company will manufacture the clocks in Japan, in Europe, in Mexico and at new facilities recently completed in the United States. ROTC staffs new men take special courses Air Force and Army officers repoi’ting to Texas A&M for ROTC instructional duty this fall have done extra work toward classroom teaching assignments. Eleven officers in the Depart ments of Aerospace Studies and Military Science completed pro fessional courses at Maxwell AFB, Ala., and Fort Sill, Okla., announced Col. Thomas R. Par sons, commandant and professor of military science. Other military personnel al ready in teaching capacities at the university went through the special courses before assign ment here. Army officers are in a one- week methods of instruction course at Fort Sill, building on teaching methodology instruction all Army officers receive as part of the basic officer course taken when they first go on active duty. The Sill course is being taken by Lt. Col. Donald E. Smith, Maj. Thomas L. Avant, Maj. Russell Pierre Jr., and Maj. Benjamin R. Schlapak. The course includes lesson plan preparation, lecture techniques, use of training aids such as mo dels, terrain tables, slides and films and “things not to do,” such as distracting mannerisms that reduce student concentration on subject matter. Seven Air Force officers in cluding the n e w professor of aerospace studies, Col. Robert F. Crossland, attended a five-week Academic Instructor Course (AIC) at the Alabama base. They are Maj. Dean D. Dun can, Maj. Milton R. Halbert, Maj. Frederick J. Mitchell, Capt. Pat rick H. Corbett, Capt. Karl W. Koch Jr. and Capt. Wayne L. O’- Hern Jr. Corbett taught fresh man air science at A&M during 1970-71. Also assigned to the Air Force detachment at Texas A&M this year is Maj. Melton G. Holubec, a member of the AIC faculty on his last assignment. The accredited five-week Air Force course covers teaching methods, communication skills, educational psychology and coun seling. Crossland pointed out that many of the AIC profes sional staff are Air Force offi cers with the Ph.D. in education. All new AFROTC instructional personnel going to college or uni versity assignments are required to attend the course, unless they have had adequate prior teaching experience.
