  • Patent number: 4274362
    Abstract: Within the sump of a dry developing, magnetic brush system in an office copier machine, twisted strips of aluminum sheet metal are used to form an auger blade mixing arrangement for the purpose of mixing dual component developer. Each auger blade is formed from strip sheet metal into a single, elongated helical convolution and is appropriately journaled at each end for the application of rotative power. In addition, the auger blades have smooth, rounded, axial edges which provides extended useful life to the carrier constituent due to reduced shearing effects.

  • Patent number: 4084901
    Abstract: A copying machine in which a photo-receptor sheet, wound between supply and take-up reels, serves as an intermediate web which is charged, exposed and developed with toner; the toner then being transferred to copy paper. The photo-receptor sheet is advanced incrementally from the supply reel to the take-up reel during each copy cycle. After substantially all of the sheet is wound on the take-up reel, it is rewound on the supply reel, following which it is moved once again in incremental steps in the forward direction during copy cycles. The supply and take-up reels are mounted in a highly compact module which is easily plugged into or removed from the base section, without requiring any threading of the photo-receptor sheet over elements within the base section. In this way, practically all that is required during a service call to replace the photo-receptor sheet is to substitute one module with a new photo-receptor sheet for the previously used module with the old photo-receptor sheet.
