Abstract: An inkjet printing system includes an ink reservoir defining an ink-receiving chamber and a control chamber, a control fluid source fluidly communicating with the control chamber, and an orientation sensor configured to determine an orientation of the ink reservoir and generate an orientation signal. A processor is operably coupled to the control fluid source and the orientation sensor, the processor programmed to determine a desired pressure for the control chamber based, at least in part, on the orientation signal, and control the control fluid source to adjust an actual pressure level in the control chamber to the desired pressure for the control chamber.

Abstract: An inkjet printing system includes an ink reservoir defining a longitudinal axis, an ink-receiving chamber and a control chamber. A control fluid source delivers a control fluid across a range of pressure levels to the control chamber, and an orientation sensor determines an orientation of the longitudinal axis of the ink reservoir and generates an orientation signal. A processor is operably coupled to the control fluid source and the orientation sensor, the processor being programmed to infer an angle of the longitudinal axis relative to the vertical reference axis based on the orientation signal from the orientation sensor, determine a desired pressure for the control chamber based, at least in part, on the inferred angle of the longitudinal axis, and control the control fluid source to adjust the actual pressure level in the control chamber to the desired pressure for the control chamber.

Abstract: Among other things, for jetting ink, a first set of orifices of an apparatus are arranged to print at a first maximum resolution along a direction different from a process direction. A second set of orifices is coupled to the first set of orifices. The second set of orifices is arranged to print at a second maximum resolution lower than the first maximum resolution along a direction different from the process direction.

Abstract: A support member attached to a support surface is rotated about a threaded stud to change the distance between an object on the support member and the support surface. The support member is fixed relative to the stud when the desired distance is attained, and a nut is fastened onto the stud, thereby trapping the object between the nut and the support member, and fixing the distance between the object and the support surface.

Abstract: A method for constructing a bridge joint in a channel overlying an expansion joint involves lining the channel with a thermoplastic asphaltic elastomeric binder followed by successive applications of layers of aggregate and binder mixture wherein the thickness of each layer is restricted to about the maximum dimension of the aggregate in the layer. Care is taken to insure that both the binder and the aggregate are hot when the layered joint is formed to insure good bonding between layers and with the roadway material. The aggregate of each layer is raked to project upwardly from the mass of the layer before a subsequent layer is applied to enhance the interlock between layers. A final layer containing smaller aggregate is applied at the joint top and the joint is then sealed and rolled to form an integrated, resilient load bearing structure.
