20130075487Atmospheric Condensate Collector and Electrospray Source - An atmospheric condensate collector and electrospray source apparatus. The apparatus has a cooler having a surface with a sharp point. The cooler generates a condensate from ambient atmosphere exposed to the cooler. A ground electrode is electrically and mechanically separated from the cooler. A high voltage power supply switchably provides a high voltage between the sharp point of the cooler and the ground electrode. A controller is electrically connected to the cooler power supply and the high voltage power supply. The controller controls the operation of the cooler power supply and the high voltage power supply. The atmospheric condensate collector and electrospray ionizer apparatus generates the condensate and generates particulate spray from the condensate in response to command signals issued from the controller.

20090008469SPRAY DEVICE HAVING A PARABOLIC FLOW SURFACE - A rotary atomizer spray coating device, in certain embodiments, has a bell cup with a generally parabolic flow surface. This generally parabolic flow surface provides additional surface area for dehydration of coating fluids, thereby improving color matching as compared to traditional bell cups, for example, by affording capability for higher wet solids content. In addition, the coating fluid accelerates along the generally parabolic flow surface, resulting in the fluid leaving the bell cup at a greater velocity than in traditional bell cups. Furthermore, a splash plate disposed adjacent the bell cup, in certain embodiments, is designed such that fluid accelerates through an annular area between the splash plate and the generally parabolic flow surface. This acceleration may substantially reduce or eliminate low-pressure cavities in which fluid and/or particulate matter may be trapped, resulting in an even application of coating fluid and more effective cleaning of the bell cup as compared with traditional bell cups.01-08-2009
