Hogan, formerly of the Bell Telephone Laboratories, is noted for his successful construction of the microwave gyrator, which in principle permits the simultaneous transmission and reception of a single frequency from the same antenna. Trefethen is currently doing research in the field of fluid mechanics and heat transfer in liquid metals. Since 1951 he has been Technical Aide to the Director of the National Science Foundation in Washington...
...unseen traffic cop is a radar meter. Of several brands the most commonly used is a 40-lb. aluminum-sheathed box with two sets of antennas and a price tag of $1,100.* It fits snugly into the rear of a prowl car. As a speeding car approaches, the meter's transmitting antenna sends out high-frequency radio waves that bounce off the car, change frequency and are picked up by the receiving antenna. The difference between the two frequencies tells the speed accurately (within 2 m.p.h.). (In a group of cars, the meter picks out the one that...
...Sight. An aluminum TV antenna that promises good reception to televiewers 100 miles from stations has been developed by the Channel Master Corp. of Ellenville, N. Y. The antenna is made of two newly designed high-frequency antennas, one on top of the other, plus a gridlike reflector for picking up TV signals. Price: $20.83 plus installation...
Only one of the three floors is fully occupied at present. This one, the third floor, is being used for work in electromagnetic radiation, solid state physics, and physical electronics. The group experimenting in electromagnetic waves also uses a penthouse on the roof of the building for antenna research. A unique feature of this installation is a ground-screen on top of the penthouse that will give the scientists the equivalent of an infinite plane for their experiments...
...Folksy Touch. As one of some 111,000 U.S. radio "hams" (his call letters: W9UG), Turner operates a mass-production listening post in a barn next to his suburban Northbrook home. With the help of a technician, three 35-foot directional antenna masts, eleven short-wave receivers (six are permanently tuned to catch Moscow, London, Paris, Seoul, Buenos Aires and Melbourne) and three tape recorders, he collects most of the short-wave signals aimed...
