  • Patent number: 7032783
    Abstract: A pump dispenser for liquid products includes a pump chamber having a cylinder, and a piston slidable within the cylinder with an outlet passage extending through the piston. A spring within the chamber urges the piston to an extended position. An inlet opening is disposed at an end of the chamber for receiving product to be dispensed. An inlet check valve is positioned at the inlet opening to permit entry of product into the chamber as the piston is extended by the spring, but to prevent exit of product from the chamber through the inlet opening as the piston is depressed against the spring. An outlet check valve is carried by the piston within the outlet passage to permit discharge of product from the chamber through the outlet passage as the piston is depressed against the spring.

  • Patent number: 7008407
    Abstract: A urine collection device (10) that is made up of a flexible, thermoplastic urine collection bag (20), which receives urine through a molded plastic inlet fitment (30) that is secured to an upper end of the bag 5 and discharges urine through a two-piece molded plastic valve fitment (40) at a lower end of the bag. The inlet fitment, which has no check valve therein, has a series of steps gradually reducing lateral extent as it extends longitudinally from the bag to a free end thereof, and each of the steps extends at a non-perpendicular angle to the longitudinal central axis of the inlet fitment. The bag is also free of any check or flutter valve. The outlet valve fitment has a fixed outer element (42) surrounding an inner element (44) that is rotatable with respect to the outer element to selectively open or close the outlet valve fitment to flow.

  • Patent number: 6692117
    Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

  • Patent number: 6585359
    Abstract: An ink container for an off-carriage printing system including an ink supply station. The ink container contains a collapsible reservoir filled with ink that is in fluidically connectable to a conduit that leads to a pressure regulator. The outlet of the regulator delivers ink to a printhead. A pressure vessel surrounds the reservoir. The system pressurizes the pressure vessel, which results in pressurized ink being delivered to the regulator. The ink container has a sensor that infers the actual volume of ink in the reservoir by sensing the relative position of the reservoir walls. This sensor is mounted between the pressure vessel and the collapsible reservoir. The sensor is electrically connected to pads that are accessible from the outside of the ink container. Leads route from the pads, through a seal zone, and to the sensor. The seal is provided by a compressed o-ring.

  • Patent number: 6386675
    Abstract: An ink container for holding a supply of liquid ink for use in an inkjet printing system. The container includes a collapsible ink reservoir for holding a supply of liquid ink, and a multiple functioned chassis. The chassis rigidly supports an air inlet for receiving pressurized air from the printing system and an ink outlet for delivering pressurized ink to the system. The chassis supports a collapsible ink container by providing an attach surface over which the collapsible container is attached. The attach surface allows a relatively simple pleated bag construction to be used by providing a surface whose normal is substantially perpendicular to the longitudinal axis of the container. The chassis is adapted to engage with a pressure vessel opening, providing a seal that separates the pressure vessel from an outside atmosphere.

  • Patent number: 6017118
    Abstract: An ink container for an inkjet printing system is described, including an assembly of a simple housing with caps bearing indicia and protective surfaces to enable effective handling, aligning, keying and latching of the ink container. The ink container includes an ink container housing, the housing including an ink reservoir and a fluid outlet in fluid communication with said reservoir. The fluid outlet is for providing ink to the inkjet printhead. The container further includes a separately fabricated first cap attached to an end of the housing, the first cap having a plurality of mechanical features that provide mechanical functions for the ink container. The end of the housing is a leading end relative to a direction of insertion of the ink container into the printing system. The mechanical functions can include positioning the ink container relative to the supply station, a keying function for preventing installation of an ink container in the supply station without a cap providing the keying function.

  • Patent number: 5784087
    Abstract: An ink containment and dispensing device for an inkjet printer is provided with a main reservoir in the form of a flexible pouch panel, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink.

  • Patent number: 5113311
    Abstract: An improved electrical panel assembly of the type providing a plurality of receptacles for use with cable connectors and requiring that the connectors must be connected with their respective receptacles in a given order and disconnected therefrom in the reverse of that order. The panel assembly comprises a planar panel element having an opening therein for each receptacle and a receptacle mounting housing element behind each panel opening, constituting an integral, one-piece molding. Each panel opening is provided with a cover swingable between a closed position and an open position. The connectors and receptacles are of the known type having single contacts which lock together when the connector is mated with the receptacle and rotated a partial revolution. Polarizing devices are provided in association with each receptacle and each cable connector.

  • Patent number: 4795360
    Abstract: Mateable receptacle and plug assemblies comprising a cable connector for use in a nuclear environment. The receptacle assembly and the plug assembly comprise mateable metallic shells, each surrounding one or more cable ends terminating in contacts. The contacts of the receptacle assembly and the plug assembly are equal in number and mateable. In each of the receptacle assembly and the plug assembly, the space between the shell and the cable ends and their contacts is filled with one or more heat, steam and radiation resistant insulative elastomeric compounds and/or epoxy compounds to prevent hosing of steam and moisture through the cables. The inside surfaces of the shells are uniquely configured to enhance bonding thereof to the insulative compounds, providing baffles creating pressure drops should the bond fail. O-rings are mounted on the plug assembly shell which cooperate with the receptacle assembly shell to form compression and butt seals to prevent leakage through the shell faces.
