Abstract: This invention relates to document motion detention devices and, more particularly, to protection of original documents from burning or tearing in graphic information scanning and transporting systems. A time delay circuit is provided wherein a switch is continuously energized and deenergized to control the operation of associated circuitry for the external control of a lamp or other control circuitry. If this switch remains opened or closed for a length of time due to a malfunction within the external control circuitry, the time delay circuit would deenergize said external circuitry to prevent damage to said original documents.

Abstract: Apparatus for producing facsimile copies having high resolution and uniformity from electrostatically charged latent images on a dielectric support member in which a quantity of developer material comprising a uniformly dispersed toner material is transported into transfer relation with the dielectric support member having the latent electrostatic images thereon. The developer material which includes a magnetically attractable carrier material is supported on the applicator member by means of an attractive force generated by a suitable magnetic field. The toner is maintained at a uniformly dispersed concentration in the developer material by means of concentrically arranged screw conveyor members which provide a continuously recirculated supply of developer material in position to be attracted to the cylindrical applicator member.
