    摘要： A remote air temperature indicator is provided wherein a thermister is used as a temperature sensing element followed by a stable linear amplifier whereby a linear readout is provided on an analog-type meter. Preferably the thermistor is a composite thermistor network having a wide range of linearity from low to high temperatures.

    摘要： A peak holding circuit is provided wherein an analog voltage from a tachometer is converted to and stored as a digital value and the digital value is converted back to an analog voltage and compared continuously with the tachometer output and corrected when the digital value falls below that of said output. A practical application of the circuit is described wherein the peak value of an anemometer is stored for indefinite lengths of time.

    摘要： AN IMPROVED COMPASS CARD WHEREIN THE MAGNETIC PORTION OF THE CARD IS PROVIDED IN THE FORM OF SMALL MAGNETIC PARTICLES EITHER IN THE BODY OF THE CARD AS SUCH OR AS A LAYER APPLIED OVER AT LEAST ONE FACE OF THE CARD. THE MAGNETIC PARTICLES HAVE A MAGNETIZATION OF SUBSTANTIALLY THE SAME INTENSITY WHILE THEIR DIRECTION OF MAGNETIZATION IS AT AN ANGLE OF SUBSTANTIALLY 20* TO THE AXIS OF REVOLUTION

    OF THE CARD. A CARD SO CONSTRUCTED IS FREE OF THE GYRATIONAL MOTION WHICH CHARACTERIZES CARDS USED HERETOFORE AND WHEREIN SEPARATE MAGNETS WERE SUPPORTED UPON THE CARD.
