Miniaturizing n automatic amino acid analyzer for use on Apollo mission and Mars Voyager mission
Piezojunction effect in miniature solid state pressure transducer
Miniature pressure transducer responds to static or dynamic pressures acting against a structural surface without introducing errors caused by stresses in the structural surface. This is accomplished by a thin stainless steel pressure sensing diaphragm with an attached foil strain gage.
Miniature pressure transducers in compact water-cooled mounts are placed in hotter and more confined environments than previously possible. It quantitatively measures high frequency total pressure fluctuations resulting from rotating stall in an axial flow engine compressor.
Miniature spray gun regulates paints and other liquids to spray at close range, facilitating spraying of remote or recessed areas. Individual valves for regulating air pressure and paint maximizes atomization for low pressure spraying.
Miniature King-type furnace, consisting of an inductively heated, small diameter tantalum tube supported in a radiation shield eliminates the disadvantages of the conventional furnace in obtaining absorption spectra of metal vapors.
Miniature tunnel diode transducers having operation related to controllable band gap modulation mechanism
Miniature piezojunction pressure transducer incorporating GaSb and GaAs tunnel diodes
Miniature piezoelectric ceramic transducer for broad band wall pressure fluctuation measurements, noting frequency response and calibration
Miniature skull mounted multiple connector for small animals suitable for brain stimulation work
Miniature, portable resuscitation system is used during evacuation of patients to medical facilities. A carrying case contains a modified resuscitator head, cylinder of oxygen, two-stage oxygen regulator, low pressure tube, and a mask for mouth and nose.
Miniature telemetry device for transmission of electrical activity of brain nerve cells
Hydrogen burning annular combustor in miniature gas turbine engine for wind tunnel tests for obtaining aerodynamic characteristics
Hydraulic characteristics of flow through miniature slot orifices for rocket engine injectors
Miniature plug and receptacle, which eliminates the need for permanent fixed leads, is used on wind-tunnel force balances, in the interface connections of microelectronic modular assemblies, and in electric and electronic systems where subsystems must be removed or interchanged.
Miniature electromechanical tunnel diode transducer
Two-axis fluxgate miniature magnetometer designed for sounding rockets with mathematical models and Fourier analysis of output waveforms
