In some examples, a print bar includes a body, a plurality of printing fluid dispensing devices mounted to the body, and an assembly to carry a printing fluid to the printing fluid dispensing devices. The assembly comprises a first part having outlets to receive the printing fluid from a first conduit, and a second part attached to the first part, the second part having inlets aligned with the outlets of the first part, the second part to carry the printing fluid to the plurality of printing fluid dispensing devices. The assembly further comprises a pliable gasket comprising first and second flat sealing surfaces sealing the first and second parts around a first inlet of the inlets and a first outlet of the outlets, the first flat sealing surface contacting a ridge on one of the first and second parts, and the second flat sealing surface contacting a flat surface on the other of the first and second parts.

Fluid carrying assembly

In one example, a print bar structure includes a beam having two flanges connected by a web and a planar surface along a longitudinal edge of each flange, a printhead mounting structure attached to the beam along the planar surfaces to mount a printhead, and a fluid flow structure positioned between the flanges to carry printing fluid to the printhead mounting structure.

Print bar structure

In one example implementation, a printhead assembly includes a fluid intake section, a fluid interconnect integrated with the fluid intake section to receive fluid from an ink supply assembly, and an air-permeable, fluid-resistant, fluid interconnect cover installed over the fluid interconnect.

Printhead assembly with fluid interconnect cover

In one example, a processor readable medium has instructions thereon that when executed cause a printer to: introduce an unsaturated printing fluid into a channel through which fluid may pass to a printhead; dispense unsaturated printing fluid with the printhead to remove air from the channel; and then introduce regular printing fluid into the channel; and dispense printing fluid with the printhead until regular printing fluid is dispensed from the printhead.

Removing air from a printing fluid channel

In one example, parts to be assembled into a fluid flow structure include: a first part having flat sealing surfaces each surrounding one of multiple first conduit openings; a second part having sealing ridges each surrounding one of multiple second conduit openings; and a single gasket having multiple holes each surrounded on both sides by a flat sealing surface. Each hole in the gasket is positioned to align with one of the first and second conduit openings so that, when the parts are assembled together, each gasket sealing surface contacts a corresponding one of the flat sealing surfaces on the first part or the sealing ridges on the second part and fluid may flow through the holes in the gasket from the conduit openings on one of the parts to the conduit openings on the other part.

Fluid flow structure

A cap assembly is usable with a print head device having nozzles to eject fluid there through. The cap assembly includes an outer cap member, a sealing member, an intermediate cap member, and at least one resilient member. The outer cap member includes a main portion, at least one hinge portion to engage with the print head device to allow movement of the outer cap member toward the print head device to place the nozzles in a cap state, at least one latch portion to engage the print head device in the cap state, and at least one pedestal support portion extending outward from the main portion. The sealing member may seal the nozzles of the print head device in the cap state. The intermediate cap member may be disposed between the sealing member and the outer cap member. The intermediate cap member may support the sealing member. The at least one resilient member may be disposed between the sealing member and the intermediate cap member to provide a sealing force on the sealing member to seal the nozzles of the print head device in the cap state. Additionally, the at least one pedestal support portion may be configured to contact an external surface to support the print head device in the cap state.

Cap assembly for print head device

A unitary multiple seal mechanism includes a tubular sealing member having a longitudinal axis, and a second sealing member radially displaced from the tubular sealing member and connected to the tubular sealing member by a flexible connection.

Unitary multiple seal mechanism

An apparatus including an electrical switching device to control current to a load and a second case arranged to substantially encapsulate the electrical switching device. The electrical switching device includes a first case; a plurality of contacts disposed in the first case; and an opening in the first case disposed to expose the contacts. The second case is arranged to duct a blast from the opening of the first case of the electrical switching device.

Electrical switching component

A system, including an enclosure and a module, where the module is disposed in the enclosure such that a tab of the enclosure is disposed in a slot of the module; and the module is configured to rotate about the slot. The enclosure can also be configured to receive modular mounting structures. The enclosure can also include multiple panels that create a smaller opening.

Electrical component enclosure

A fuel supply includes a fuel container having an interior chamber for containing fuel, and a pressure sensing unit disposed within the interior chamber of the fuel container. The pressure sensing unit is configured to provide an output signal indicative of an amount of fuel remaining in the fuel container.

Apparatus and method for integrating a fuel supply and a fuel level sensing pressure sensor

Techniques are disclosed for improving pressure sensor shock robustness in fluid containment devices by providing a mechanical filter configured to prevent high-frequency pressure shocks from damaging the pressure sensor. One approach includes a body of elastomeric material disposed on an external surface of the sensor. Another approach is a porous plug in a fluid pathway leading to the sensor. Yet another approach is to provide a seal structure with a labyrinth fluid path.

Labyrinth seal structure

Damage is prevented in printing systems by allowing fluid from the printing system's fluid delivery system to expand. In one embodiment, this is accomplished by fluidly connecting a fluid expansion receptacle to the fluid delivery system. The fluid expansion receptacle provides volumetric compliance so that if printing fluid in the system expands, such as due to freezing, the fluid is able to expand into the fluid expansion receptacle and not damage the printing system.
