Abstract: An ink tank cartridge includes a housing having a chamber in which ink is stored. A screen is secured to a surface of the housing through which an outlet passage communicates with the chamber. The screen is fused to the first surface by melting a continuous portion or bead around the outlet passage with a heated ram, ultrasonic welding, laser welding, etc. A vacuum can be applied through the outlet port to assist in locating and removing wrinkles from the screen. A recess can also be provided in the first surface of the housing to locate the screen and allow the ink absorbing member, filled with ink, to form a liquid-tight seal with the remainder of the first surface about the recess.

Abstract: A method of filling ink into a dual chamber inkjet cartridge (A) for used with an ink-jet printer includes applying a vacuum to the cartridge (A) through a fill hole (52) of the cartridge (A) to substantially eliminate air within an ink absorbing member (40) of the cartridge (A). The fill hole (52) is sealed and then ink is pressure filled into the cartridge (A) through the fill hole (52). A vacuum is again applied to the cartridge (A) to substantially eliminate any residual air in the cartridge (A) due to the pressure filling of the ink. The fill hole (52) may be positioned over a free ink chamber (24) or over the ink absorbing member (40) of the cartridge. The vacuum includes applying a negative pressure of about 27.in/Hg. The negative pressure is applied at a cycle rate of 5-30 seconds.

Abstract: An ink cartridge (10) for dispensing ink (IK) having a housing (12) with a cavity (22) therein for storing a quantity of ink, and a dispensing port (26) for delivering the ink to an output recordation device, such as a printer. The housing further having one or more additional ports (32, 34) extending through the housing in fluid communication with the cavity, and a self-sealing plug (16) received in one of the additional ports. The self-sealing plug being pierceable by a hollow instrument (H), such as a needle, to form a fluid passage therethrough, the self-sealing plug re-forming a fluid-tight seal in the port upon the removal of the hollow instrument.

Abstract: An ink tank cartridge (A) includes a housing (10) having a bottom wall (28) and a plurality of side walls (12, 14, 16, 18) forming a cavity (20). A divider wall (22) is positioned within the cavity to divide the cavity into first and second chambers (24, 26). An ink supply port (42) projects from the bottom wall of the housing. A porous member (40) is accommodated in the chamber having the ink supply port. The other chamber is partially filled with ink. The divider wall has an opening (30) allowing ink to pass from one of the chambers to the other chamber. A cover (50) having a fill hole (94) is secured to the housing.

Abstract: An ink refill bottle for a modified inkjet printhead cassette which has a rear wall opening through which the refill bottle may be inserted comprises a front wall connected to a rear wall by sidewalls to form an ink reservoir chamber, a foam adaptor for drawing ink from the ink chamber when called for by the printhead cassette, and an air inlet metering device for metering air into the ink chamber to replace the ink drawn from the ink chamber and for retaining the remainder of the ink in the ink chamber.

Abstract: A hanging-folder file frame for hanging folders which have two rigid top edge members with end hooks, and a web which extends downwardly from one top edge member to a fold line and extends upwardly from the fold line to the other top edge member, comprises a first U-shaped end frame member which has a base portion with two legs that extend upwardly from the base portion and terminate in top portions, a second U-shaped end frame member which has a base portion and two legs that extend upwardly from the base portion and terminate in top portions, a pair of side rails that extend between the first and second U-shaped end frame members, and corner caps which connect the ends of the rails to the top portions of the end frame legs. The corner caps have key holes that receive keys formed in the top portions of the legs to present rotation of the corner caps. The top edge members of the hanging folders cross brace the file frame.

Abstract: Assembly fixtures for assembling and stuffing a ribbon into a ribbon cartridge for use with a typewriter, or a printer, comprises a base plate, stops on the base plate forming a space for receiving a ribbon cartridge, and an instruction card mounted on the base plate for instructing the operator how to assemble and stuff a ribbon cartridge. The instruction card may include three-dimensional drawings of the ribbon cartridge and its parts. A method of assembling and stuffing a ribbon cartridge includes the steps of providing an assembly fixture having a base plate and a ribbon cartridge space providing instruction cards mounted on the base plate for instructing an operator, guiding the ribbon cartridge into the cartridge space on the base plate, and following the instructions mounted on the base plate to assemble and stuff the ribbon cartridge.

Abstract: A ribbon cartridge comprises a housing having a bottom wall and a side wall extending upwardly therefrom to form an open top, a cover adapted to fit over the open top of the housing to close the housing to form a ribbon cartridge, an output arm and a take-up arm formed in the cartridge with a print space between the arms, the cartridge being adapted to hold a ribbon stuffed inside and extending between the arms from the output arm to the take-up arm, flexible fingers which are spaced apart from each other and attached at their base portions to the housing, with each finger being positioned in a finger opening in the bottom wall of the housing, whereby when an end tab of a finger meets resistance from a top wall of a correction cartridge, the finger is pushed into the interior of the housing, and when an end tab of a finger does not meet such resistance, it actuates the typewriter switch to actuate the typewriter.

Abstract: Tape feed control apparatus for a correction tape cassette 11 for a typewriter for controlling the amount of correction tape being fed to a printing point for lifting-off or covering-up a typed character, comprises a housing 13, a post 15 mounted in the housing 13, a brake finger 17 pivotally mounted on post 15 so that an end portion 17a of the brake finger 17 is in frictional contact with correction tape 18 on a take-up spool 19 to hold the tape firmly on the take-up spool 19, a spring 20 in contact with brake finger 17 urges a brake finger end portion 17a against the tape 18 on the take-up spool 19, an opening 25 in the sidewall 13a of housing 13 admits a typewriter metering post 26 into the housing 13, a stop member 27 formed in the housing 13 limits the travel of typewriter metering post 26 into housing 13, the stop member 27 is stationary so that its position does not change in response to the amount of correction tape 18 on the take-up spool 19 so that the distance travelled by the metering post 26 corr
