COMBINATION OF LOCAL HEATING AND RADIOMETRY BY MICROWAVES

Duc Dung Nguyen, Maurice Chivé, Yves Leroy, Eugène Constant · 1980

Researchers presented new methods combining microwave heating and radiometry at the same frequency range. Two processes were tested: an alternate process with periodic temperature measurements and a sampling process with pulsed power.

Microwave Diathermy Products; Performance Standard

Unknown authors · 1980

The proposed standard covers microwave diathermy products operating from 890 MHz to 22.125 GHz. Current equipment shows excessive stray radiation and minimal energy deposition in target tissues. The standard would apply to cancer therapy devices with possible variances.

Early Research on the Biological Effects of Microwave Radiation: 1940-1960

Harold J. Cook et al. · 1980

The authors review how two factors, possible medical use of microwaves for diathermy and uncertainty about radar hazards, shaped early biological effects research. Hazard reports in the late 1940s and early 1950s led to near abandonment of medical diathermy research while military and industrial concern grew. This culminated in the Tri-Service program, a massive research effort from 1957 to 1960.

Bio-electromagnetic research: review of some important aspects

A temperature regulating circuit for experimental localized current field hyperthermia systems

Melvin A. Astrahan, F. W. George III · 1980

The authors present a temperature regulating circuit for experimental localized current field hyperthermia systems using general purpose components. The circuit uses a variable attenuator with a field effect transistor controlled by thermistor feedback to modulate radiofrequency power. The design was tested in both animal studies and patient treatment with excellent results.

Program Assessment Report Statement of Findings - Satellite Power Systems Concept Development and Evaluation Program

Unknown authors · 1980

The report states what is known, uncertain, and unknown about the Solar Power Satellite concept of collecting solar energy in space and delivering it to Earth for baseload electricity. The Concept Development and Evaluation Program aimed to develop an initial understanding of the technical feasibility, economic practicality, and social and environmental acceptability of the SPS concept by the end of 1980. A reference system was defined using a 2.45 GHz microwave beam with a power density of 23 mW/cm2 at the center and 0.1 mW/cm2 at the exclusion zone fence line.

Electronic office of the '80s

Unknown authors · 1980

Electronic mail systems use packets that contain address, routing, security, and error-recovery information determined by protocol. Xerox's Project Alto integrates keyboards, screens, storage, and printers into a wideband network and is used by the National Bureau of Standards and the Swedish government. Western Digital's 2501 chip formats messages to HDLC protocol and transmits at 80 pages per second (1 Mbit/sec) with a price around $200. Data General's Dasher terminals connect via dial-up to a support center for fault diagnosis, and their industrial computers have self-checks that light indicators on faulty circuit cards.

Radio-Frequency Drying of Fungal Material and Resultant Textured Product

H.F. Huang, R.A. Yates · 1980

Researchers used a platen-electrode dielectric dryer at 85 MHz and 8.5 kW to prepuff extruded fungal mycelial fibers, then finish-dried the chunks in a 60°C hot-air oven for 16 hours. The extrudate shrank about 20% in length during radio-frequency heating with little further shrinkage during finish drying. Rehydration improved as initial free interstitial water was removed, with samples prepuffed to below 70% moisture rewetting well and softness increasing as moisture decreased. The method was found viable over frequencies from 27 MHz to 2450 MHz, with resilience and hydration controlled by the prepuffing termination moisture level.

A Simple Method for Indicating the Electric Field Distribution in a Microwave Oven

S. Washisu, I. Fukai · 1980

Toner particles melt and adhere to warmed portions of a bakelite plate while unheated particles can be removed by tapping. Partially melted toner corresponded to approximately 72°C and completely melted toner to 120°C temperature rise. Toner removed from the test plate could be reused making the method low cost compared to liquid media.
