<p>1,176,226. Film-strip perforations. TEVERAMA S.A. March 31, 1967 [May 3, 1966], No. 14986/67. Heading G2C. In a cinematographic film-strip having at least two sequences of images, the image of one sequence being inter-calated with the images of the other, at least one perforation 3 is of slot-like configuration formed by joining two consecutive normal perforations 1, 2 together. Thus if the driving claw forming the intermittent film feed "loses" the phase by jumping from the right perforation to the wrong one, because of damaged perforations, or for any other reason, it is able to correct itself when it enters the slotted perforation.</p> |
