Description
Известны устройства дл кинопроекции и киносъемки, в/которых лента движетс непрерывно, а дд освещени служит лампа, питаема током с острой формой кривой -и дающа отдельные эспышки синхронно со.сменой кадров в окне.There are known devices for film projection and filming, in which the tape moves continuously, and the dd illumination is a lamp powered by a current with a sharp curve shape - and giving separate outlines synchronously with the replacement of frames in the window.
Сущность данного изобретени заключаетс в том, Ато с целью получени прерывистого освещени , последовательно с дугой, питаемой переменным тОком оответствующёй частоты, включена реактивна катушка, имеюща сйлсцно насыщенный железный сердечник.The essence of this invention is that in order to obtain intermittent illumination, Ato, in series with an arc fed by a variable current of the appropriate frequency, includes a reactive coil having a saturated iron core.
В качестве I прерывистого источника света может быть применена дуга с угольными или металлическими электродами, в частности, с ртутным катодом. Как показано на схематическом чертеже, устройство дл кинопроекци состоит из конденсора 7, объектива 2 и барабан 5 дл прот гивани ленты 4...An arc with carbon or metal electrodes, in particular, with a mercury cathode, can be used as the I discontinuous light source. As shown in the schematic drawing, the device for film projection consists of a condenser 7, a lens 2 and a drum 5 for drawing a tape 4 ...

частоту переменного 1гока ic величине, наболее удобной дл кинопроекции, последовательно с дугой 6 включена реактивна катушка 7 с сильно насыщенным железным сердечником, служаща дл создани коротких импульсов тока. От Того же источника тока питаетс синхронный мотор 5, привод щий во вращение барабан 5 транспортирующего механизма. Дуга 5 может быть снабжена приспособлени ми дл управлени ее зажиганием.the frequency of the alternating current, ik, more convenient for film projection, in series with arc 6, is a reactive coil 7 with a highly saturated iron core, which is used to create short current pulses. A synchronous motor 5 is powered from the same current source, driving the drum 5 of the transporting mechanism. Arc 5 can be equipped with controls to control its ignition.
Аналогична схема может быть применена и в устройстве дл 1йгаосъемки в ателье, при чем импульсами тока регулируетс свет ламп, служащих дл освещени объекта.A similar scheme can also be applied in a device for shooting at a studio in which the light of the lamps used to illuminate the object is regulated by current pulses.
Дл специальных целей научной киносъемки , баллистической кинематографии и пр. то же устройство может примен тьс с токами высокой частоты от специальных МИШИН или ламповых генераторов, при чем частота ограничиваетс только допустимой скоростью перемещени пленки и ее светочувствительностью.For special purposes of scientific filming, ballistic cinematography, etc., the same device can be used with high-frequency currents from special MISHINs or lamp generators, and the frequency is limited only by the allowable speed of the film and its photosensitivity.
