Abstract: A photocopy machine having a drum and associated rollers driven by a flexible drive belt. A first gear train is connected between the drive belt and the drum for driving the drum at a low speed. A second independent gear train is connected between the drive belt and the rollers for driving the rollers at a relatively high speed, the gear trains being connected to the belt at points separated from one another. The drum and rollers are mounted in a drawer frame providing "pull out" movement with respect to a main frame. First and second one-way clutches of the axially separable type are interposed in the respective gear trains and axially oriented between the frames for completing separate drive connections in the trains when the drawer frame is closed in operating position, with the drive connections being broken when the drawer is pulled out for inspection or servicing.

Abstract: A cassette and heating arrangement for a photocopy machine having a transport system including an in-feed roller with conventional components for acting upon a sheet to produce a developed image during transport of the sheet from an entry way to a discharge slot. A copy sheet cassette is provided including a shallow rectangular tray for a stack of copy sheets having a cover hinged at the rear end of the tray to extend over the top of the tray but foreshortened to leave the front portion of the tray uncovered. The housing of the machine has a receptacle at the entry way for plugging in the cassette with the front portion of the cassette being totally accommodated within the housing and with the front portion of the stack of sheets carried by the cassette in engagement with the in-feed roller.

Abstract: Finely comminuted particles of a normally solid thermoplastic organic polymer, which is particularly useful as a toner base for electrostatic reproduction utilizing pressure fusing on the toner, is prepared by dissolving a polymer in a normally solid first solvent, cooling the resulting solution to form a friable solid, and removing the first solvent from the solid, preferably by extraction with a normally liquid, relatively volatile, second solvent in which the polymer is substantially insoluble. When using the process to make magnetic mono-component toners, powered magnetic material and/or carbon black or other pigment are added to the solution of polymer and first solvent.
