Patent number: 6701663Abstract: An apparatus and method for dispersing a volatile composition, which comprises dispersing the composition into an air stream and generating an ion wind, thereby causing the molecules of the composition to become electrically charged. The composition can be an insect repellent, an insecticide, an anti-microbial, an anti-allergenic or a room-fragrancing composition.Type: GrantFiled: September 25, 2001Date of Patent: March 9, 2004Assignees: Reckitt Benckiser (UK) Limited, University of SouthamptonInventors: John Farrell Hughes, Rodney Thomas Fox, Jennifer Jane Knapp, Neale Mark Harrison, Lindsey Faye Whitmore

Patent number: 6612510Abstract: A method of improving the spraying of liquid droplets from a spray device onto a surface which method comprises imparting a unipolar charge to the said liquid droplets by double layer charging during the spraying of the liquid droplets from the spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least ±1×10−4 C/kg, whereby the charged droplets of the liquid are mutually repelled thereby increasing the spread of the droplets from a central spray line extending from the head of the spray device and avoiding coalescence of the droplets, thus providing a more even coverage of the surface which is to be sprayed. In particular, the method enables liquid droplets to be sprayed onto a surface which is obscured by all object located between the surface and the spray device.Type: GrantFiled: June 8, 2001Date of Patent: September 2, 2003Assignees: University of Southampton, Reckitt Benckiser (UK) LimitedInventors: Rodney Thomas Fox, Neale Harrison, John Farrell Hughes, Duncan Roger Harper, Lindsey Faye Whitmore
-
Patent number: 6592813Abstract: An improved method of counteracting or neutralizing airborne malodour comprising directing at the source of the malodour liquid droplets from a spray device containing a malodour counteracting composition, the improved method comprising imparting a unipolar charge to the said liquid droplets by double layer charging during the spraying of the liquid droplets by the spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least ±1×10−4C/kg.Type: GrantFiled: July 11, 2001Date of Patent: July 15, 2003Assignees: University of Southampton, Reckitt Benckiser (UK) LimitedInventors: Rodney Thomas Fox, Neale Harrison, John Farrell Hughes, Duncan Roger Harper, Lindsey Faye Whitmore
