Abstract
A number of miscellaneous improvements in laboratory apparatus are described, which have for their object the elimination of spots, scratches, and unevenness of density in processed motion picture film. Modifications in developing room equipment include a vacuum cleaner for removing sludge from developers, a cooling coil for adjusting developer temperature, a new type of rack guide for a developer tank, a compact rack light lock, a waterproof and corrosion-resisting portable darkroom lamp, and some auxiliaries for the prevention of spots and contamination on film. Improvements in printing room equipment include the addition of a flywheel to a continuous printer to eliminate unevenness in density due to variation in the motion of the film during exposure. Also, a light change has been equipped to control either of two lamps of different wattage giving in each case exposure values which have precisely equal relationships. Some changes have been made in rewinding equipment which include the addition of a weighted roller to make more firmly wound rolls and a large portable winding core. The design of a standard disk rewind has been changed to facilitate removal of the wound roll. A film storage cabinet has been designed for laboratory use which gives an increased degree of protection from fire and water, at the same time assisting in the convenient and orderly arrangement of the film.
