Description

В основном авторском свидетельстве № 12301 описано устройство дл  записи звуков на кинематографической ленте, в котором в поле посто нного магнита на пути пучка лучей, идущих от источника света к кинематографической лент ,е, помещены включенные в цепь микрофона две тонкие проволочки, несущие затемн ющую пластинку. Предлагаемое изобретение  вл етс  дальнейшим развитием упом нутого выше устройства.The main author's certificate No. 12301 describes a device for recording sounds on a cinematographic tape, in which two thin wires carrying a darkening plate included in the microphone circuit are placed in the field of a permanent magnet in the path of a beam of rays coming from a light source to the cinema tapes. . The present invention is a further development of the above device.

На чертеже фиг. 1 изображает схему видоизмененного устройства; фиг. 2-вид части киноленты с многократной записью.In FIG. 1 shows a diagram of a modified device; FIG. 2-view of the part of the film with multiple recording.

Дальнейшее изучение рптической системы и законов колебаний нити показало , что применение алюминиевых нитейдает возможность в значительной степени подн ть частоту собственных колебаний и, кроме того, уменьщить толщину нити. Поэтому, в устройстве, описанном в основном патенте, можно примен ть весьма тонкие нити, помещаемые между двум  оптическими системами, заключенными в полюса посто нногоFurther study of the polymer system and the laws of oscillation of the thread showed that the use of aluminum filament makes it possible to significantly increase the natural frequency and, moreover, reduce the thickness of the thread. Therefore, in the device described in the main patent, it is possible to use very thin filaments placed between two optical systems placed in the poles of a constant

магнита. Число нитей может быть примерно четыре или п ть, причем эти нити проектируютс  по всей ширине кинопленки и дают на ней р д различных кривых соответственно различным токам, проход щим через эти нити.magnet. The number of filaments can be about four or five, and these filaments are projected across the entire width of the film and give her a number of different curves, respectively, different currents passing through these filaments.

Предложенна  запись дает возможность получить на одной пленке (фиг. 2) одновременно запись самых разнообразных электрических  влений, причем запись более совершенную, чем возможно было получить до сих пор, ибо чем тоньше нити, тем тоньше и из щнее записи и тем чувствительнее осциллограф.The proposed recording makes it possible to simultaneously record a wide variety of electrical effects on a single film (Fig. 2), and the recording is more advanced than it was possible to obtain so far, for the thinner the filament, the thinner and warmer the recording and the more sensitive the oscilloscope.

Предмет изобретени .The subject matter of the invention.

Видоизменение устройства дл  записи звуков на кинематографическую ленту по авторскому свидетельству № 12301, отличающеес  применением нескольких нитей, например четырех-п ти, с целью использовани  всей ширины ленты и одновременного получени  на ней зaпиcj р да различных электрических  влений.A modification of the device for recording sounds on a cinematic tape according to author's certificate No. 12301, characterized by the use of several threads, for example, four or five, in order to use the entire width of the tape and at the same time record a number of different electrical effects on it.
