An apparatus for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

A system (10) produces patterned deposition on a substrate (14) from compressed fluids. A delivery system (12) cooperates with an independently controlled first chamber and an independently controlled second chamber retaining a substrate (14) for receiving precipitated functional material along a fluid flow delivery (13) from the delivery system (12). A shadow mask (22) is arranged in close proximity to the substrate (14) for forming the patterned deposition on the substrate (14).
A method and apparatus for delivering a functional material to a receiver includes a pressurized source of solvent in a thermodynamically stable mixture with a functional material. The solvent is in a liquid state within the pressurized source. A discharge device having an inlet and an outlet is connected to the pressurized source at the inlet such that the thermodynamically stable mixture is ejected from the outlet. A receiver having a back is positioned a predetermined distance from the outlet of the discharge device. The solvent of the thermodynamically mixture evaporates at a location beyond the outlet of the discharge device and a predetermined amount of the functional material contacts the receiver at a predetermined distance from the back of the receiver.
A particulate dispensing device includes a housing having a wall at least partially forming a housing cavity. A dispersive element and a particulate filter are each supported in the housing cavity in spaced relation to one another forming a fluidizing chamber. A dispensing tube extends from the fluidizing chamber for dispensing fluidized particulates or aerosol from the device. The particulate dispensing device generates the fluidized particulates or aerosol from a particulate bed within the fluidizing chamber, and dispense the particulates through the dispensing tube to a downstream delivery site. One or more dispensing devices can be used in a system to deliver the fluidized particulate matter to the delivery site. In one system a delivery line from an associated dispensing device directly delivers particulate matter to the delivery site. In another system, each delivery line of one or more dispensing devices delivers particulate matter to an associated delivery member that includes a longitudinally extending channel having an exit orifice. A propellant source is in fluid communication with a propellant port in the channel, and provides propellant flow along the channel. The dispensing lines deliver the fluidized particulate matter or aerosol into the propellant flow. The delivery site is supported adjacent the exit orifice such that the propellant flow and particulate matter therein are delivered to the delivery site.
Aerosol emissions within an inkjet printer are reduced. A printhead of the inkjet printer is fired using a first set of firing conditions when firing conditions are critical for printing performance. When firing conditions are not critical for printing performance, the printhead is fired using a second set of firing conditions. The second set of firing conditions is optimized to provide reduction of aerosol jets.
Various systems and techniques are disclosed for stopping, selectively controlling, and optimizing a flow of particles in a flowing stream. The systems and techniques utilize a multi-electrode assembly and various voltage waveforms applied to those electrodes. The particles flow past or near the electrode assembly and their flow is controlled by the configuration and arrangement of the electrodes and the voltage waveforms applied thereto. An additional strategy for countering particle leakage flow is also described.
