Abstract: An apparatus for the automatic microfilming of documents of different formats and the development of exposed microfilms in a continuous process. The apparatus includes a computer controlled combination of (a) an installation for the automatic insertion of documents and their transport through an exposure device from a stack of documents of a certain format, with means to adjust to a given format; (b) an interchangeable lens camera with an illumination and mirror system for the simultaneous imaging of the front and reverse side of the document and with an automatic film transport device; (c) a camera with an exposure system for the filming of titles and continuous identifications; (d) an automatic film development installation; and (e) a central guide and control system with an input keyboard, a monitor and a processor.

Abstract: An apparatus for the development of microfilm passes film successively through different work stations, such as the developer bath, fixing bath, preliminary washing bath, second washing bath and a drying stage. The film moves in a horizontally arranged track with the aid of a motor driven pair of rolls. The apparatus is characterized by a liquid circulation system in which each vessel supplying a liquid station with a liquid and designed as a transport container is equipped with a supply line and a suction line. The suction line moves the liquid to a bath by means of a liquid pump and by way of pressure lines through a heating means. A bath may be associated with each work station. In the bath the liquid is sprayed against the bottom side of the film travelling in the horizontal direction and is returned through a liquid and film guiding body and the supply line into the vessel.
