Patent number: 7152817Abstract: An electrostatic spray device and a cartridge for an electrostatic spray device that reduce the occurrence of electrically induced emulsion product separation are disclosed. The device and/or the cartridge may reduce electrically induced emulsion product separation by providing a conductive high voltage shield substantially around the product reservoir. Alternatively, the device and/or the cartridge may prevent the product located at the charging location from being in fluid communication with the product reservoir so that the product that is being charged cannot flow back into the product reservoir. The device and/or cartridge may alternatively reduce electrically induced emulsion product separation by minimizing the volume of product between the charging location and the exit orifice of the nozzle.Type: GrantFiled: January 12, 2001Date of Patent: December 26, 2006Assignee: The Procter & Gamble CompanyInventors: David Edward Wilson, Bryan Michael Kadlubowski, Jeffrey Keith Leppla, Wataru Hirose, Yoshihiro Wakiyama, Takeshi Aoyama, Takeshi Mori, Toru Sumiyoshi, Joseph Michael Crowley

Patent number: 6814318Abstract: An electrostatic spraying device being configured and disposed to electrostatically charge and dispense a product from a supply to a point of dispersal. This device has a reservoir configured to contain the supply of product and a nozzle to disperse the product. A channel is disposed between the reservoir and the nozzle, wherein the channel permits the electrostatic charging of the product upon the product moving within the channel. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A portion of the high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge the product within the channel at a charging location. A mixing mechanism may be disposed between the reservoir and the nozzle to reconstitute any product which may have separated. The high voltage contact may be spring biased in direction towards the high voltage electrode.Type: GrantFiled: January 12, 2001Date of Patent: November 9, 2004Assignee: The Procter & Gamble CompanyInventors: David Edward Wilson, Bryan Michael Kadlubowski, Jeffrey Keith Leppla, Toru Sumiyoshi

Patent number: 6682004Abstract: The present invention is an electrostatic spraying device to electrostatically charge and dispense a product from a reservoir to a point of dispersal that includes a nozzle having an exit orifice and being disposed at the point of dispersal to disperse the product. A channel is included that permits the electrostatic charging of product. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A power source supplies an electrical charge. A portion of a high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge product within the channel at a charging location. A distance between the charging location and the nozzle exit orifice is governed by Vo/d<100,000, wherein Vo=an output voltage of said high voltage power supply and d=linear distance between the charging location and said nozzle exit orifice.Type: GrantFiled: January 12, 2001Date of Patent: January 27, 2004Assignee: The Procter & Gamble CompanyInventors: Bryan Michael Kadlubowski, David Edward Wilson, Jeffrey Keith Leppla, Wataru Hirose, Yoshihiro Wakiyama, Takeshi Aoyama, Takeshi Mori, Yoshito Komada, Toru Sumiyoshi, Joseph Michael Crowley

Publication number: 20010020653Abstract: An electrostatic spray device that maintains a consistent charge-to-mass ratio in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that the charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. During shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjusted to maintain a consistent charge-to-mass ratio.Type: ApplicationFiled: January 12, 2001Publication date: September 13, 2001Inventors: David Edward Wilson, Bryan Michael Kadlubowski, Jeffrey Keith Leppla, Wataru Hirose, Yoshihiro Wakiyama, Takeshi Aoyama, Takeshi Mori, Toru Sumiyoshi
