Description
Дл получени звуковой записи автор предлагает BKaK)4aTb в цепь маловольтной лампы накаливани - микрофон, при чем свет этой лампы проектируетс через щель на движущуюс фильму и этим путем звуки фотографируютс . Опытным путем было установлено, что включение в цепь катодного усилител - микрофона не только измен ет катодный поток, но также мен ет и излучаемость лампы накаливани , котора мен етс настолько сильно, что световые изменени сно заметны на глаз. Световые изменени могут быть непосредственно сфотографированы, при чем при таком способе фотографировани может быть вз та люба маловольтна лампа накаливани , а также термотелефон . Схема расположени приборов показана на прилагаемой схеме, где А - лампа (катодна при комбинированном использовании изменений потоков светового и катодного или обыкновенна ) или термотелефон, В - рефлектор , С-система линз, Д - экран с щелью, Е - фильма.To get a sound recording, the author offers BKaK-4aTb to the low-voltage incandescent lamp-microphone circuit, and the light of this lamp is projected through the slit on the moving film and sounds are photographed by this way. It was experimentally established that the inclusion of a cathode amplifier microphone in the circuit not only changes the cathode flux, but also changes the emissivity of the incandescent lamp, which varies so much that light changes are clearly visible to the eye. Light changes can be directly photographed, and with this method of photographing any low-voltage incandescent lamp as well as a heat telephone can be taken. The layout of the devices is shown in the attached diagram, where A is a lamp (cathode with combined use of changes in light and cathode fluxes or ordinary) or a thermotelephone, B is a reflector, C is a lens system, D is a screen with a slit, an E film.
ПРЕДМЕТ ИЗОБРЕТЕНИЯ.SUBJECT OF INVENTION.
