Sonar Locator Systems

An underwater locator device called a Pinger is attached to an airplane's flight recorder for recovery in case of a crash. Burnett Electronics Pinger Model 512 resulted from a Burnett Electronics Laboratory, Inc./Langley Research Center contract for development of a search system for underwater mines. The Pinger's battery-powered transmitter is activated when immersed in water, and sends multidirectional signals for up to 500 hours. When a surface receiver picks up the signal, a diver can retrieve the pinger and the attached airplane flight recorder. Other pingers are used to track whales, mark underwater discoveries and assist oil drilling vessels.

Pressure Relief Valve

"Sputtering" is the process of applying film-like metal coatings onto a surface by bombarding the coating material with electrocharged ions. This causes the material to disintegrate and relocate on the substrate an atom layer at a time. The process allows a variety of coating materials to be deposited on various surfaces. Deposition Technology, Inc. (DTI) uses "sputtering" for window films, packaging materials, etc. Valves installed on two vacuum chambers which are part of DTI's system, were developed by Lewis Research Center and detailed in Tech Briefs. The valve protects the environment and frees the operator from monitoring the chamber venting.

Technology for Television

A project being conducted by Varian Associates, Inc. and Lewis Research Center would allow a Ultrahigh Frequency (UHF) TV station to save 50% of its electricity cost. Because UHF stations need substantially more transmitter power, an amplifying device was needed. In the early 1970's Dr. Henry Kosmahl of Lewis had developed a radiowave amplifier to improve satellite transmission. He later worked with modifying klystron transmitters, electronic vacuum tubes used to generate and amplify UHF frequencies. If Dr. Kosmahl's multistage depressed collector or MDC can be incorporated into the klystron, the magnetic field shapes of electron beams can be changed to aid the energy recovery function of the MDC.
