Abstract: A toner cartridge splitter provides for the opening of the two major portions of a powdered toner cartridge, as used in various xerographic photocopy machines and printers. The device serves to separate the toner reservoir and mounting portions of a toner cartridge, thereby allowing the cartridge to be replenished with toner and resealed for further use, rather than merely being discarded after a single use. A toner cartridge is placed within the cartridge receptacle portion of the splitter, with the cartridge being immovably secured therein during the operation. A splitter blade is disposed coplanar with the seam of the cartridge between the two major components, and is driven between the two cartridge components to split them apart. A clearance notch may be provided in the blade to clear any protrusions in the cartridge rim which might otherwise block the penetration of the blade into the seam.

Abstract: A bag dispenser, for separating and dispensing a series of plastic bags where one end is attached to the top of the next bag by perforation lines with a slot therebetween. The series of bags are dispensed from a device comprising a wire frame formed into channels to support the core that the series of bags are rolled onto. The channels allow the core to rotate in place but restrict its linear movement to the vertical direction. The dispenser has two braking devices, a braking bar underneath the roll of bags and a pair of fingers that are attached to the channels to engage the core. The braking bar is positioned transversely to the series of bags so that it supports them. The pair of fingers does not engage the core until the number of bags on the core has decreased and the core has begun to descend. The two braking devices work in combination to retard the rotation and dispensing of the bags and thus to apply a tension to the series of bags.
