Abstract

27,723. Tatham, J. E. Dec. 9. Kinematograph apparatus.-A clean blast of air is directed upon a kinematograph film from nozzles O, O<1> arranged at about 45 degrees to the plane of the film and having orifices not exceeding one-eighth of an inch in diameter. The air is supplied from a reservoir J kept filled by means of an oscillating-cylinder pump G which requires no internal lubrication.
