Abstract: A development system which includes a dual auger assembly, mounted in a housing, for mixing developer materials in which a trickle port is between the dual auger assembly at an end of the housing which enables combining the cleaner waste toner and trickle waste in a single without the need of an additional auger.

Abstract: A toner cartridge is provided for dispensing toner on demand to the development station of a xerographic copier machine. The cartridge is modified so as to improve the dispensing of toner through dispensing ports located at one end of the cartridge by the provision of a relatively stiff, coiled spring element which is fixed in position adjacent the interior walls of the cartridge. As the cartridge rotates, the spring moves through the toner acting as an auger-type transport mechanism to move the toner towards the dispensing ports. The spring also serves to agitate the toner so as to make its consistency more fluid thereby aiding the augering transport motion. In one embodiment, the toner cartridge is tilted so as to utilize additional gravitational forces to assist in the toner transport towards the dispensing end.

Abstract: An apparatus which dries and fuses a liquid image of liquid carrier and toner particles to a sheet. The sheet passes through a nip defined by a support member cooperating with a roller. The roller contacts the liquid image on the sheet. Heat is applied to the liquid image to fuse the toner particles to the sheet and vaporize at least a portion of the liquid carrier therefrom. The side of the sheet opposed from the side having the liquid image thereon is maintained at a lower pressure than atmospheric pressure to reduce the amount of heat required to vaporize the liquid carrier and remove the vaporized liquid carrier therefrom.

Abstract: A closure for a sterilizer or other pressure vessel, the door having a compound motion to permit swinging movement on hinges and lateral sliding movement with respect to the hinges.
