The Cinébloc projector is not mentioned in the Ariel Register. 22mm. Ozaphan cellophane film was produced in 1922 with a conventional layout of a row of peforations each side of the image. It seems to have had a very short-lived existence. The gauge differs considerably from Edison's 22mm. Home Kinetoscope film, which positioned three strips of images and two central perforations across its width.

The 17.5mm. gauge, also with two rows of perforations at the edges of the film, was launched by Pathé in 1926 and achieved only limited success.
