摘要:
An improved method and system for non-contact powder image development are provided. The present technique implements a 5-stage jumping development cycle where the initial stage is a momentary over-voltage condition to release the majority of the toner on a donor substrate and the final stage includes the implementation of a decelerating potential to minimize return impact on the donor and therefore toner abuse. It also uses a routine to directly determine improved (e.g. up to optimal) waveform amplitudes and pulse widths based on toner size and q/m, guided by physical insight.

摘要:
An electrocoagulation system including a dosing unit, a mixing unit and a buffer tank is provided. The dosing unit receives a fluid from an external source and injects an electrochemically generated coagulant into the fluid using one or more pairs of electrodes. The mixing unit mixes the coagulant with the fluid and is separate from the dosing unit. The buffer tank holds the fluid until particles contained in the fluid grow to a predetermined size.
摘要:
Fluidic structures for facilitating particle separation in curved or spiral devices are provided. The contemplated systems relate to various fluidic structures, implementations and selected fabrication techniques to realize construction of fluidic separation structures that are of a stacked and/or parallel configuration. These contemplated systems provide for efficient input of fluid to be processed, improved throughput, and, in some variations, adjustable and efficient treatment of output fluid.
摘要:
A coagulation generating system that combines the advantages of conventional and electrocoagulation. In the coagulation generating system electro-coagulation is performed on an input (e.g., salt/brine) solution to generate a concentrated coagulant solution, which is then added to the source water in the same way as a standard stored chemical coagulant.

摘要:
A method 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.

Provided is a standalone integrated water treatment system for a distributed water supply including a filter input, a coagulation system in operative connection with the filter input, wherein the water is subjected to a coagulation process to create pin floc from suspensions in the water. A maturation buffer tank in operative connection with the coagulation system aggregates floc in size within the water. A spiral separator separates the water into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is configured to receive the first stream of water and perform a filtration operation thereon. A sterilization system is configured to perform a sterilization operation on the first stream of water. The water is then output from the sterilization system as potable water.

In one aspect of the presently described embodiments, the system comprises an inlet to receive at least a portion of the fluid containing algae, a curved channel within which the fluid containing algae flows in a manner such that the neutrally buoyant algae flow in a band offset from a center of the curved channel, a first outlet for the fluid with algae within which the band flows, and, a second outlet for the remaining fluid.

A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. A liquid marking material, such as ink, 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 marking material allow for high throughput, high resolution marking. Multiple marking 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.
