Abstract: A container assembly may include a regulated tank to contain a fluid, a free tank to replenish the fluid in the regulated tank, a first expandable member between an interior of the regulated tank and ambient atmospheric pressure, a second expandable member between the interior of the regulated tank and an inflation port, a first valve to selectively connect the free tank to the regulated tank based upon a pressure differential between the interior of the regulated tank and an interior of the free tank and a second valve actuatable between an open state permitting an interior of the free tank to be pressurized and a closed state. The second valve is actuatable between the open state and the closed state based upon a position of the first expandable member.

Abstract: Ink supplies are disclosed in examples herein. An example apparatus a housing includes a first chamber and a second chamber, the housing defining a first port to fluidly couple the first chamber to a printer, the housing including a second port to fluidly couple the first chamber and the second chamber to flow fluid from the second chamber to the first chamber. The apparatus also includes a regulator coupled between the first chamber and the second chamber, the regulator to flow gas from the first chamber to the second chamber when a pressure within the first chamber reaches a threshold.

Abstract: In some examples, a container assembly includes a first body to supply a printing composition, the first body comprising a first port, and the container assembly includes a second body to store a reserve printing composition, the second body comprising a second port. An interconnect has a storage position to fluidically isolate the first body from the second body, and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body. The interconnect in the storage position has a first orientation to fluidically isolate the first port from the second port, and the interconnect in the use position has a second orientation rotated with respect to the first orientation to fluidically connect the first port to the second port.

Abstract: A fluid seal may comprise an external sealing body, and an internal sealing body disposed within the external sealing body. The internal sealing body may be radially connected to the external sealing body by a webbing. Further, the external sealing body may hermetically seal a fluid path from the exterior of the fluid path, while the internal sealing body may hermetically seal the fluid path from within the interior of the fluid path.

Abstract: Examples of a container assembly are disclosed herein. An example of the container assembly includes a first body to supply printing composition and a second body to store reserve printing composition. The example of the container assembly additionally includes an interconnect having a storage position to fluidically isolate the first body from the second body and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body as needed to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body.

Abstract: Examples of a container assembly are disclosed herein. An example of the container assembly includes a regulated tank to supply printing composition and a free tank to supply reserve printing composition to the regulated tank. The container assembly also includes a regulator assembly to control flow of the reserve printing composition from the free tank to the regulated tank and an inflation assembly to prime the regulated tank to supply the printing composition. The container assembly additionally includes a labyrinth to fluidically isolate the flow of ambient air into and out of the regulator assembly from the flow of a supply of air into the inflation assembly.

Abstract: A web press includes a web travel path for a continuous media web between a first nip and a second nip. The web travel path includes a first portion in which the web moves in a first direction and which includes a first printer configured to print on a first side of the web. The web travel path also includes a second portion in which the web moves in a second direction, with second portion including a second printer configured to print on a second side of the web. The web travel path is configured to control a drying time via the respective first and second portions being in a generally parallel, vertically stacked relationship and with each respective first and second portion extending in a generally horizontal orientation.

Abstract: An image forming device includes a protective case, a media source disposed in the protective case, the media source supplying an image receptive media, an encoder configured to detect an advancement of the image receptive media, and a pen coupled to the protective case, the pen including an immovable print head configured to deposit ink onto the image receptive media.

Abstract: An ink containment vessel characterized by improved resistance to the corrosive effects of ink, the ability to prevent air entry into the ink, and enhanced dimensional stability. The system also avoids the evaporative loss of volatile components from the ink supply. The ink containment vessel is produced from polyethylene naphthalate, at least one liquid crystal polymer, or polyethylene naphthalate combined with at least one liquid crystal polymer. The storage of ink within vessels made from the specialized materials listed above offers multiple benefits as previously noted and substantially improves the operational efficiency of the entire ink delivery system.
