Recording of Electric Waves on Paper and its Foundation in Theory: USSR.
Abstract
Recording of Electric Waves on Paper and its Foundation in Theory. By means of this method it is possible to chemically record on white paper the presence of a multi-variable electrical field and also the track of fall or passage of electromagnetic waves; consequently to detect these without the aid of a galvanometer, thermoelectric couple, or any other instruments with wires. The method Consists of the use of a detector of the short coherer type which is provided with electrodes of different metals. The coherer lies on the paper and touches it at two points. The paper is impregnated with an indicator sensitive to current arid which changes color as a result of electrolysis after the waves strike the detector. The electrodes of the coherer can be made from the same metals, but then it is necessary to pass through the paper a current from a special battery. By distributing on the sheet of paper many such detectors, each of about one centimeter in length, after the waves strike' (illumination by waves), the paper shows the track of passage or strike of the rays in the for: of colored spots (stictography). A description is given of the electrostatics of the stictography detector, theory? of plane current in a paper with a Coherer lying on it, and the theory of static breakdown of a detector on sensitive paper. The action of the latter is regarded from the point of view of photographic sensitometry.
