Abstract: An ink cartridge includes a flexible bag filled with a liquid ink, and a cartridge housing that holds the bag. The bag is filled to a predetermined percentage of its full volume to fill the bag to less than its capacity in order to prevent the bag from rupturing, but is filled sufficiently to substantially occupy the housing when folded.

Abstract: A method of filling an ink supply bag with a liquid ink comprises flowing the liquid ink from an orifice in a nozzle extending deep into the bag and at an initial delivery velocity that is low enough to substantially prevent bubbles from forming in the delivered liquid in the bag in order to prevent the liquid ink from foaming, and after the liquid level in the bag rises to immerse at least the orifice increasing the delivery velocity to speed up the fill rate for the bag.

Abstract: A cartridge comprises a pair of housing portions having an opening at a seam formed between the housing portions, a memory chip accessible via the opening to permit electrical contact to be made with the memory chip, and a protuberance projecting from one of the housing portions and welded to the other housing portion within a cavity of the other housing portion. Since a flash which is formed at the weld can spread towards the seam including in the vicinity of the opening, the protuberance and the cavity are mutually dimensioned to restrict the flash substantially to within the cavity. This prevents the flash from spreading into the seam and bulging outward at least in the vicinity of the opening, which could interfere with formation of the seam and making electrical contact with the memory chip.

Abstract: An alternative ink/cleaner cartridge includes an egress snout from which an ink supply or a cleaner supply is discharged from the cartridge. The snout and a collar that mates with the snout are mutually configured to permit the collar to mate with the snout only when the collar is in any one of a number of allowable orientations, to provide an identification of an ink supply to be discharged from the cartridge. Alternatively, the snout mates with a cap in place of the collar to prevent a cleaner supply from being discharged from the cartridge.

Abstract: An ink cartridge comprises an ink supply bag, a fitting attached to the bag and including an integral ink egress snout, and a pair of housing halves that contain the bag and at respective wall portions have opening halves that form a bottom opening for the snout when the housing halves are connected together. The fitting and only one of the wall portions each have mutually engageable members that engage to connect the fitting and the one wall portion to secure the bag within the housing half that includes the one wall portion. The housing half that includes another of the wall portions has stakes that are adhered to the engageable members of the fitting and/or the engageable members of the housing half that includes the one wall portion.

Abstract: An ink cartridge includes a housing with an integral pocket, an ink supply bag contained in the housing, and a memory chip supported in a wall opening of the pocket. The housing has an ink blocking shield arranged at a location between the bag and the memory chip to prevent any ink that might leak from the bag from entering the wall opening and contaminating the memory chip.

Abstract: A fitting is attached to a disposable ink supply bag and has an ink egress snout for discharging an ink supply from the bag. The fitting is configured to engage with a housing for the bag to permit the bag to be connected to the housing when the ink supply is to be discharged from the snout and to disengage from the housing to permit the bag to be disconnected from the housing in order to dispose of the bag when emptied.

Abstract: An ink cartridge has a cartridge housing having a front side wall, a back side wall opposite the front side wall, a pair of opposed left and right side walls separating the front and the back side walls, and a bottom wall, the walls defining an internal cavity within the housing. The front and back side walls each have an internal surface that is curved and there is a generally uniform internal cartridge cavity thickness spacing existing between corresponding points on the respective internal surfaces at a respective section through the cartridge. An ink bag is preferably located within the internal cavity and filled with liquid ink so that the ink bag makes contact with the front side wall, the back side wall and each of the pair of opposed left and right side walls and the bottom wall.

Abstract: A silver halide light sensitive photographic element is disclosed comprising a polyethylene terephthalate film base, at least one light sensitive silver halide-containing emulsion layer, an antihalation undercoat layer, and a process-surviving antistatic backcoat, wherein the polyethylene terephthalate film base has been formed by drafting a cast resin at a stretch ratio of at least 3.4, tentering at a stretch ratio of at least 3.4, and heat-setting at an actual heat-set temperature of at least 216° C. In accordance with preferred embodiments of the invention, the polyethylene terephthalate film base of the photographic element is formed by: (a) casting a molten polyethylene terephthalate resin in a machine direction onto a casting surface to form a continuous sheet, (b) drafting the sheet by stretching in the machine direction at a stretch ratio of from 3.4 to 4, and at a temperature ranging from 70 to 130° C.
