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： This invention is based on size and mass separation of suspended particles, including biological matter, which are made to flow in a spiral channel. On the spiral sections, the inward directed transverse pressure field from fluid shear competes with the outward directed centrifugal force to allow for separation of particles. At high velocity, centrifugal force dominates and particles move outward. At low velocities, transverse pressure dominates and the particles move inward. The magnitudes of the two opposing forces depend on flow velocity, particle size, radius of curvature of the spiral section, channel dimensions, and viscosity of the fluid. At the end of the spiral channel, a parallel array of outlets collects separated particles. For any particle size, the required channel dimension is determined by estimating the transit time to reach the side-wall. This time is a function of flow velocity, channel width, viscosity, and radius of curvature. Larger particles may reach the channel wall earlier than the smaller particles which need more time to reach the side wall. Thus a spiral channel may be envisioned by placing multiple outlets along the channel. This technique is inherently scalable over a large size range from sub-millimeter down to 1 μm.
摘要翻译：本发明基于使得在螺旋通道中流动的悬浮颗粒（包括生物物质）的尺寸和质量分离。在螺旋段上，来自流体剪切的向内定向的横向压力场与向外的定向离心力相竞争，以允许颗粒分离。在高速度下，离心力主导，颗粒向外移动。在低速度下，横向压力占主导，颗粒向内移动。两个相对力的大小取决于流速，粒径，螺旋截面的曲率半径，通道尺寸和流体的粘度。在螺旋通道的末端，平行排列的出口收集分离的颗粒。对于任何颗粒尺寸，所需的通道尺寸通过估计到达侧壁的通行时间来确定。这个时间是流速，通道宽度，粘度和曲率半径的函数。较大的颗粒可能比需要更多时间到达侧壁的较小颗粒更早地到达通道壁。因此，可以通过沿着通道设置多个出口来设想螺旋通道。这种技术在从亚毫米下降到1微米的大尺寸范围内具有固有的可扩展性。

摘要： A system to facilitate separation and concentration of particles based on centrifugal force on suspended particles, including biological matter, which are made to flow in a vortex structure is provided. The centrifugal force urges larger particles to collect along outer portions of the vortex flow. Conversely, within a vortex structure, a radial hydrodynamic pressure drop is also amplified to urge smaller particles toward inner portions of the vortex flow. This force created by the pressure can reach magnitudes that encourage a sharp cut-off and improved resolution discrimination between particle sizes. Thus, separated streams of particles can be collected with both increased concentration and purification.
摘要翻译：提供了一种用于基于离心力分离和浓缩颗粒的系统，所述悬浮颗粒（包括生物物质）被制成在涡流结构中流动。离心力促使较大的颗粒沿涡流的外部部分收集。相反，在涡流结构内，径向流体动压压降也被放大，以将较小的颗粒推向涡流的内部。由压力产生的这种力可以达到鼓励锐利截止和提高颗粒尺寸分辨率的大小。因此，分离的颗粒物流可以以增加的浓度和纯化收集。

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.
