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.

Simple, accurate automatic frequency control circuit

Automatic frequency control circuit is designed for use with voltage-controlled variable-frequency oscillators. The output frequency of the circuit is determined by a crystal oscillator.

NASA NTRS1969

Automatic leveling and equalizing hoist device

Hoist uses six equally spaced support points with the load equalized between pairs to prevent over-stressing of any one point of support. The pickup point is automatically shifted through a motor driven feedback system to level the load throughout the lifting period.

Design for a Rapid Automatic Sync Acquisition System

System provides rapid command sync acquisition between widely separated transmitter-receivers. It is based on a rapid, automatic range-adjustment approach rather than the time-consuming cycle slipping or stepping techniques of conventional phase-locked loops.

Integral valve provides automatic relief and remote venting

In-line, pilot-operated, differential area, poppet type valve provides both automatic relief of a tank at a precise over-pressure and remote control of tank venting. Relief and vent operations are separate functions incorporated in an integral valve package.

Live-timer method of automatic dead-time correction for precision counting

Automatic correction for dead time losses in nuclear counting experiments is implemented by a simple live timer arrangement in which each counting interval is extended for compensation for the dead time during that interval. this method eliminates repetitious manual calculations, source of error, and dependence upon paralysis shifts.
