A system and apparatus includes a nozzle formed on a first surface of a substrate, and a fluid passage in the substrate and fluidically connected to the nozzle, the fluid passage being nonlinear along at least a portion of its length and having a cross section that varies along its length, wherein the fluid passage has a width near a second surface of the substrate that is different from a width near a bottom of the fluid passage. A system and apparatus includes a nozzle formed on a surface of a substrate, and a fluid passage defined in the substrate and fluidically connected to the nozzle, the fluid passage having a first portion that substantially lies on a first plane, a second portion that substantially lies on a second plane different from the first plane, and a connecting passage fluidically connecting the first portion to the second portion.

Internal print head flow features

An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate. Each recirculation flow path has a fluidic resistance between the nozzle end and the other location such that a recirculation pressure at the nozzle end of the flow path that results from the recirculation pressure applied at the other location of the flow path is small enough so that any reduction in flow rate below the nominal flow rate when ink is being ejected is less than a threshold, or a change in the nominal negative pressure when ink is not being ejected is less than a threshold, or both.

Recirculation of ink

In general, in an aspect, an apparatus includes a body having a hollow ink refill chamber, a plate on a side of the body, the plate having a series of posts separating a series of hollow channels adjacent to the hollow ink refill chamber in the body.

Printhead stiffening

A printhead including a body; an actuator attached to the body, and an enclosed space between the actuator and the body forms a chamber; an opening defined by the body for releasing pressure in the chamber; and a seal attached to the opening to seal the chamber while permitting pressure to be released.

Disclosed is a light weight handle assembly adapted to transport a heavy duty container which may contain sensitive electronic components. The handle assembly of the present invention generally comprises a stationary bracket which mounts to a container wall and a movable handle pivotally connected to the bracket. The bracket is formed with an inner portion that is adapted to rotatably engage with a pair of pivoting arms extending from the movable handle so that the light weight handle may easily be assembled and disassembled. Each of the pivoting arms is formed with a movable stop member which is advantageously positioned to contact and bear against stationary stop members which are attached to or are a part of the container to which the handle is attached. The stationary stop members and movable stop members each have a substantially planar contact surface which is designed such that when the movable handle is pivoted to the lifting/operative position, the movable stop members are in contact with the at least one stationary stop member with less stress in the materials than in conventional handles. The lower stresses enable a strong handle to be made of plastic material such as polyethylene.

Lightweight handle

A latch is disclosed incorporating features allowing complete actuation i.e., engagement and disengagement of a latching hook on the side of the container from a latch handle on the face of the container thus allowing actuation of the latch hook even when the latch hook is itself inaccessible. The latch also features variability in the stroke of the hook and a design allowing its construction from plastic material.
