Description

Предлагаемый пневматический экран предназначаетс , главным образом, дл  репродукционных работ в кинематографическом деле (семка надписей, плакатов и т. п.).The proposed pneumatic screen is intended mainly for reproduction works in the cinematographic business (Semka of inscriptions, posters, etc.).

На фиг. 1 изображен продольный разрез предлагаемого пневматического экрана, на фиг. 2-вид его с задней стороны и на фиг. 3-вид его с передней стороны.FIG. 1 shows a longitudinal section of the proposed pneumatic screen; FIG. 2 shows it from the rear side and in FIG. 3 is a view of it from the front.

С задней стороны доски 7 наход тс  камеры 2--2, сообщающиес  с отверсти ми 3-3 на доске 7 экрана . Камеры могут иметь различный профиль сечени : круглый, полукруглый , квадратный и т. д. На чертеже, дл  примера, эти камеры показаны пр моугольного сечени . Камеры сообщаютс  посредством труб 4-4 с трубчаты.м отростком 5. Трубы 4 к 4i могут быть снабжены кранами 6 и 6.At the rear of the board 7 there are chambers 2--2 communicating with the openings 3-3 on the board 7 of the screen. Cameras may have a different sectional profile: round, semicircular, square, etc. In the drawing, for example, these cameras are shown in rectangular section. The chambers communicate through pipes 4-4 with tubules. Process 5. Pipe 4 to 4i can be fitted with taps 6 and 6.

Если соединить трубчатый отросток 5 посредством шланга или трубы с вакуум-насосом, то воздух, при условии открытого положени  кранов б и 6i, будет высасыватьс  из камер 2-2 через отверсти  3-3 на передней доске экрана. Если наложить на экран с лицевой его стороны лист бумаги так, чтобы он покрывал отверсти  3-3i, то. вследствие образующегос  вакуу.ма в отверсти х 3-3, лист этот будет держатьс  атмосферным давлением на поверхности экрана. Если лист будет иметь малый формат, то возможно пользоватьс  только отверсти ми 3i камеры 2,, выключив дл  этого камеру 2 посредством крана 6. Применение такого экрана реко.мен-дуетс  особенно в тех случа х, когда требуетс  быстро с.мен ть листы с надпис ми и плакатами, подлежащие репродукции . Дл  установки листов на экране могут быть сделаны обозначени  и линии, определ ющие правильную установку листов определенного форлшта. Число камер 2 и отверстий 3 может быть различно и зависит от Be.nHMi-fflbi экрана и других требований . ПРЕДМЕТ ПАТЕНТА. Пневматический экран дл  репродукционных работ, отличающийс  применением доски , служащей дл  Iполдержани  оригинала и снабженной отверсти ми 3, 3, сообщающимис  jс камерами 2, 2,, соединенными тру:бами 4, 4, с кранами б, 6i, с отрост .ком 5 вакуум-насоса.If the tubular spike 5 is connected by means of a hose or pipe with a vacuum pump, the air, under the condition of the open position of the valves b and 6i, will be sucked out of the chambers 2-2 through the openings 3-3 on the front screen board. If you put a sheet of paper on the screen on the front side of it so that it covers the holes 3-3i, then. Due to the resulting vacuum in the holes 3-3, this sheet will be kept by atmospheric pressure on the surface of the screen. If the sheet has a small format, it is possible to use only the openings 3i of chamber 2, by turning off the chamber 2 for this purpose by means of a crane 6. The use of such a screen is recommended especially when it is necessary to quickly change the sheets inscriptions and posters to be reproduced. For the installation of sheets on the screen, marks and lines can be made that determine the correct installation of sheets of a certain forlsht. The number of chambers 2 and 3 holes can be different and depends on the Be.nHMi-fflbi screen and other requirements. SUBJECT OF THE PATENT. A pneumatic screen for reproduction, characterized by the use of a board that serves to hold the original and provided with holes 3, 3, connected with chambers 2, 2 ,, connected pipes: 4, 4, with valves b, 6i, with a process 5 vacuum -pump
