Patent number: 8931430Abstract: A spray applicator system is provided with a reservoir manifold assembly having a separate reservoir for each different coating to be applied. Reservoirs are filled from a coating supply system and isolated electrically from the supply system when coating is dispensed from a reservoir to the applicator. Multiple sets of reservoirs can be used, so that an empty reservoir in one set can be filled while coating is dispensed from a reservoir in the other set. The set of reservoirs in which a reservoir is being filled is isolated electrically from the applicator, and of the set of reservoirs in which a reservoir is dispensing coating to the applicator is isolated electrically from the supply system.Type: GrantFiled: April 10, 2006Date of Patent: January 13, 2015Assignee: Finishing Brands Holdings Inc.Inventors: Ghaffar Kazkaz, John P.

Patent number: 8893990Abstract: A system, in certain embodiments, includes a spray device including a frame having a receptacle configured to receive a self-contained spray can. The spray device further includes a first conductive element configured to contact the self-contained spray can, and a first electrical conductor extending between the first conductive element and an earth ground such that a first electrical potential of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the self-contained spray can is in contact with the first conductive element. The spray device also includes a corona-charging electrode positioned adjacent to a spray nozzle of the self-contained spray can. The corona-charging electrode is configured to emit a stream of ions toward the self-contained spray can such that a spray of fluid from the spray nozzle passes through the stream of ions and becomes electrostatically charged.Type: GrantFiled: February 26, 2010Date of Patent: November 25, 2014Assignee: Finishing Brands Holdings Inc.Inventors: David M.

Publication number: 20140091156Abstract: 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.Type: ApplicationFiled: December 6, 2013Publication date: April 3, 2014Inventors: David M. Seitz, Roger T. Cedoz
