  • Scanning system
    Patent number: 4291973
    Abstract: An optical scanning system is provided wherein a document in an object plane is incrementally scanned by movement of a web provided with an elongated window therethrough. Light, reflected from the document in imagewise fashion, passes through the window and is reflected by a mirror moving a synchronism with said window through a projection lens onto an imaging plane.

  • Apparatus for stacking sheets in corner registration
    Patent number: 4238066
    Abstract: Apparatus for stacking sheets in corner registration comprises a stacking surface inclined downwardly towards a registration corner and a pair of coacting sheet feed rolls of tapered cross-section adjacent the upper end of the stacking surface for directing sheets into the registration corner. With such an arrangement the sheets are so oriented that they present a leading corner to the registration corner along a line following the direction of advance and aimed into the registration corner. The rolls may be continuous or discontinuous.

  • Copying machine with constant length scanning beam
    Patent number: 4196455
    Abstract: A copying machine is provided for reproduction of a stationary original by progressively scanning a surface of the original and directing a scanning beam on to a photosensitive device which either generates an image of the original or an electric signal representing that image. A photosensitive device is mounted on the carriage and the beam is reflected back and forth in parallel with the surface such that the overall length of the scanning beam remains constant during scanning.

  • Doctoring means
    Patent number: 4020788
    Abstract: An apparatus controls the pressure of a doctoring means against an applicator surface to compensate for charges in the ambient temperature. The apparatus comprises a set of jaws which bring the doctoring means to pressure contact with the applicator surface upon closing and a means for limiting the closing of the jaws at lower temperatures to provide doctoring under reduced pressure at lower temperatures.

  • Sheet stripping device
    Patent number: 4004802
    Abstract: A device for stripping sheet material from a sheet carrying surface moving relative thereto including a finger having a sheet contacting portion at a first end adjacent said sheet carrying surface to contact the lead edge of a sheet of material on said surface, said finger being pivoted about a point spaced from and upstream of said sheet contacting portion whereby the pivot point is behind the lead edge of said sheet material when it is engaged by said sheet contacting portion.

  • Electrostatographic transfer with air
    Patent number: 3977779
    Abstract: An electrostatographic system in which liquid developer material in an image pattern on a photoconductive plate is transferred to a support material by pressing the latter against the plate by air pressure from a perforated chamber adjacent to, but spaced from the plate. The perforations may be angled in the direction of movement of the plate, and the chamber may have an inclined wall.
