Description

Предлагаемое приспособление предназначено дл  нанесени  монтажных отметок на движущейс  пленке или готовом фильме. Подобно ранее предлагавшимс  приспособлени м этого рода, в данном случое также применен перфоратор , управл емый электромагнитом. Новизна предложени  заключаетс  в том, что перфоратор выполнен в виде свободно вращающегос  зубчатого колеса, укрепленного в сердечнике электромагнита , прижимающего это колесо к движущемус  фильму при включении его обмотки в цепь источника тока.The proposed fixture is intended to apply mounting marks on a moving film or finished film. Like previously proposed devices of this kind, in this case a perforator controlled by an electromagnet was also used. The novelty of the proposal lies in the fact that the perforator is made in the form of a freely rotating gear wheel, reinforced in the core of the electromagnet, which presses this wheel to the moving film when its winding is turned on to the current source circuit.

Чертеж изображает сложный разрез приспособлени .The drawing depicts a complex section of the device.

Приспособление состоит из укрепл емой на кожухе лентопрот жного механизма железной плиты 1, снабженной четырьм  щтифтами 2 из немагнитного металла. На эти штифты надета свободно перемещающа с  по ним ч елезна  колодка 3, отжимаема  пружинами 4 из немагнитного .металла, навитыми на штифты 2.The device consists of an iron plate 1 fixed to the casing of the tape-carrying mechanism, equipped with four chafts 2 made of a non-magnetic metal. These pins are worn with a shoe 3 moving freely over them, pressed by springs 4 of a nonmagnetic metal wound on pins 2.

Колодка 3 снабжена выемкой, в которой установлено свободно вращающеес  на оси колесо 5 с острыми зубцами , служащее перфоратором. В плите 7 предусмотрена выемка 6 дл  вхождени  в нее зубцов колеса 5. На колодку 3 навита проволока, образукэща  электромагнитную катушку.Block 3 is provided with a recess in which a wheel 5 with sharp teeth, which is freely rotatable on an axis, serves as a perforator. A recess 6 is provided in the slab 7 for the teeth of the wheel 5 to enter into it. A wire is wound on the block 3, forming an electromagnetic coil.

При включении тока в катущку 7 колодка 3 прижимаетс  к фильму 8 и колесо 5, враща сь, наносит на фильм отметки в виде просечек. Включение тока производитс  нажатием на кнопку, котора  может быть помещена в просмотровом зале, в аппаратной камере или в ином месте. Дл  возвращени  колодки 3 в исходное положение при выключении тока в обмотке электромагнита служат пружикы 4. Дл  надежности вращени  зубчатого колеса 5 при его соприкосновении с фильмом, на его оси, по обе стороны от него можно насадить два узких барабанчика, обт нутых резиной , которые при прикосновении с кра ми фильма обеспечат надежАость вращени  колеса 5. Кроме того автор указывает на возможность применени  крас щего валика, с целью нанесени  колесом 5 цветных отметок на фильм, подобно тому, как это описано в сов. патенте № 12543. В этом случае фильм должен быть обращен эмульсионной поверхностью в сторону колодки 3.When current is turned on in the coil 7, the pad 3 is pressed against the film 8 and the wheel 5, rotating, causes marks in the form of notches on the film. The current is switched on by pressing a button that can be placed in the viewing room, in a hardware chamber or elsewhere. Springs 4 are used to return the pad 3 to its original position when the current is turned off in the electromagnet winding. For reliable rotation of the gear wheel 5 when it is in contact with the film, two narrow drums that are covered with rubber can be mounted on its axis touching the edges of the film will ensure that the rotation of the wheel 5 is reliable. In addition, the author points to the possibility of using a paint roller in order to apply 5 color marks on the film to the wheel, just as described in owl. patent number 12543. In this case, the film should be turned emulsion surface in the direction of the pad 3.
