This invention relates to an toner cartridge to dispense toner to a developing system in a photocopying device. The cartridge has a primary baffle thereby forming a main chamber and a dispensing chamber. The dispensing chamber is divided into a primary dispensing chamber and a secondary dispensing chamber by a secondary baffle. Apertures are formed in the container adjacent to the secondary dispensing baffle. The cartridge is designed to be rotated in one direction to fill the secondary dispensing chamber with toner, and then rotated in an opposite direction to dispense the toner from the secondary dispensing chamber through the apertures.

This invention relates to a cross-mixer for a developer system of a photocopier, particularly one with a two component development system, which mixes the developer mixture (1) to assure uniform lateral distribution of the toner, (2) to assure uniform concentration of the toner mixture and (3) to triboelectrically charge the developer mixture. Adjacently offset rows of V-shaped baffles successively divide and intermix the developer mixture. Angled lifting plates interposed between successive rows of baffles scoop and lift the mixture so as to triboelectrically charge the same.

This invention relates to a feed device which automatically straightens sheets prior to their being fed. A nudge wheel feeds the paper into the apparatus against a registration gate thereby straightening the sheet. At the appropriate time, a solenoid actuated clutch initiates a mechanically sequenced series of events which raise a set of feed tires so as to pinch (hold and secure) the previously straightened sheet, lower the registration gate out of the paper path, and start the feed tires and allow the sheet to be fed. At a second appropriate time after the sheet has been fed, the solenoid clutch is de-energized. Stored energy in a spring is used to mechanically reverse the sequence, whereby the feed tires are lowered out of the paper path and the registration gate is raised up into the paper path, preparatory to the next sheet.

A system for reducing hydrocarbon emissions from a high speed liquid reprography process. Hydrocarbon ladened vapors from the reprography process are directed through an activated charcoal bed. The bed is regenerated from time to time by a flow of controlled temperature regenerating air. Whereas the reprography process generates hydrocarbons at a highly fluctuating rate and mixed in large volumes of air, the carbon bed regeneration produces hydrocarbons at a controlled rate in a small volume of air. These hydrocarbons are removed by removal means which may be either a catalytic reactor or a condensation device.

A braking mechanism for decelerating copy sheets being delivered to a stacking tray of an electrophotographic copier includes pairs of opposing feed rollers disposed at closely adjacent longitudinally spaced locations along the sheet path to the tray. The first pair of rollers are driven at a peripheral velocity equal to that of the upstream portions of the sheet transport assembly, while the second pair of rollers are driven through an overrunning clutch at a peripheral velocity equal to about one-third to one-half the velocity of the first pair of rollers. A copy sheet entering the nip of the second pair of rollers from the first pair of rollers acts as a rigid member to drive the second pair of rollers at the upstream velocity, overrunning the clutch. When the sheet emerges from the upstream nip, frictional drag slows the second pair of rollers down to the slower velocity of their drive source, causing the sheet to be delivered to the copy tray at a relatively low rate of speed to ensure even stacking.
