Ring laser angle encoder

Ring laser angle encoder with a scanning photometer autocollimator and an isolation axis, provides continuous digital readout. It measures the angular difference in inertial attitudes of target /any phenomena generating or reflecting a light beam/ two at a time relative to target one at a time.

Coccoli, J. D.↗

Remote balance weighs accurately amid high radiation

Commercial beam-type balance, modified and outfitted with electronic controls and digital readout, can be remotely controlled for use in high radiation environments. This allows accurate weighing of breeder-reactor fuel pieces when they are radioactively hot.

Eggenberger, D. N.↗

Apparatus automatically measures soluble residue content of volatile solvents

Solvent Purity Meter /SPM/ automatically measures the soluble residue in volatile solvents used in cleaning or extraction of oils, greases, and other nonvolatile materials. The SPM gives instantaneous and continuous readout of soluble contaminant residues in concentrations as low as one part per million of solution.

Oswalt, F. W.↗

Versatile telemonitoring system

Small scale versatile multichannel telemonitoring can be installed economically with considerable expansion capabilities. This system contains a data transmitter, control transmitter, control receiver, display of readout units, a sync generator, and some remote control features.

Fergus, R. W.↗

Ground testing the Apollo vehicle.

Static structure ground test for Saturn-Apollo vehicle short stack, describing air pressure simulation, data acquisition and readout systems

Reese, D. R.↗

Improved apparatus for continuous culture of hydrogen-fixing bacteria

Improved apparatus permits the continuous culture of Hydrogenomonas eutropha. System incorporates three essential subsystems - /1/ environmentally isolated culture vessel, /2/ analytical system with appropriate sensors and readout devices, /3/ control system with feedback responses to each analytical measurement.

Foster, J. F.↗

Motor brush wear measured with strain gages

Balanced bridge circuit, supplied with low-voltage direct current and connected to a readout device, measures remaining brush material, rate of brush wear, armature runout, and brush signature.

Farrell, W. T.↗

Very high frequency digital rangine system

Digital ranging system measures slant range /from 500 feet to 200 nautical miles/ and provides digital range readout during range tracking between any two airborne vehicles.

Sobel, S. E.↗

Electronic strain-level counter

Counter for aircraft counts and records number of times the strain at a point in a structural member exceeds each of four preset levels. Counter uses 28 volt dc power supply, metallic resistance strain gage bridge as sensor, integrated and solid state circuits for signal processing, and electromechanical counters for data storage and readout.

Pitts, F. L.↗

Quasilog scaler

Quasi-logarithmic readout of conventional binary scaler provided by reduced logic system following generalized equations
