    The purpose of this research was to determine the feasibility of reception of radio telegraphic signals by the sense of taste. Electrodes were made which could be placed against the tongue in such a way as to cause a taste sensation when a source of potential was connected to them. Tests were made, using low potential direct current and 60-cycle alternating current to ascertain the amount of energ... View full abstract»

    Messrs. Goldsmith and Dickey have undoubtedly broken new ground in their work on physiological reception of radio signals, and altho the results thus far obtained do not indicate that their method will generally replace aural reception or the more recent Hoxie recorder, it is certainly within the bounds of possibility that some such form of reception may develop into a practical thing for special ...

    Amplified and rectified energy from static is stored in a large condenser in the output circuit of a vacuum tube. The condenser discharge current thru a high resistance and sensitive galvanometer wi'l, under given conditions, be a measure of the average static. The experimental arrangements are described, as to calibration and actual use. View full abstract»

    A bibliography of oscillating arc investigations with coupled circuits is given. A special form of circuit, wherein the arc and the antenna circuit are coupled electrostatically thru an arc "series condenser,'' and a "shunt condenser," is studied analytically. Experimental results on the same circuit are given, and the practical usefulness of the circuit discussed. View full abstract»

    The author starts from the consideration of the equivalent circuit to a three-electrode vacuum tube amptlifier. After pointing out the engineering usefulness of such an equivalent circuit, there is derived the equivalent circuit to a three-electrode vacuum tube modulator. The resulting theory is applied to a practical example in modulator design and its usefulness demonstrated. View full abstract»

    The general theory of the power output of a number of dissimilar vacuum tubes operated in parallel is given. The equations obtained are applied to the case when all the tubes have the same amplification constant, and also the case when the tubes all have the same internal resistance. Some practical examples are given. View full abstract»
