Patent number: 9362020Abstract: A method of making a dry type insulation is provided. The method includes combining a base fiber having a first outer surface with a binder material wherein the base fiber has a first melting point and the binder material has a second melting point which is different from the first melting point, heating the base fiber and binder material to a temperature above the second melting point, but below the first melting point using a double-belt press to form a resultant dry type insulation, compressing the base fiber and binder material using the double-belt press to form the resultant dry type insulation and cooling the resultant dry type insulation using the double-belt press.Type: GrantFiled: June 8, 2011Date of Patent: June 7, 2016Assignee: Waukesha Electric Systems, Inc.Inventors: Thomas M.

Patent number: 7303143Abstract: A wick assembly is provided for use in a dispensing device that dispenses volatile material from a wick by heat. Two wick sections of differing material are provided in stacked fashion, with a coupler sleeve that can be used to facilitate attachment of the wick structure to a reservoir. One wick section preferably provides control over the rate of dispensing, where the other provides improved thermal resistance and resistance to clogging.Type: GrantFiled: June 24, 2004Date of Patent: December 4, 2007Assignee: S.C.

Patent number: 7195139Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives gas propellant from a portion of the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel, and thereby initiate a spray burst of the main active chemical. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.Type: GrantFiled: June 29, 2004Date of Patent: March 27, 2007Assignee: S.C. Johnson & Son, Inc.Inventors: Thomas Jaworski, Nathan R. Westphal, Padma P. Varanasi, Darren K. Robling, Joel E. Adair, Chris A. Kubicek

Patent number: 7070121Abstract: An atomizer 10 atomizes a multi-component liquid from a reservoir 20 into a cloud 14 comprising small droplets 38 which are ejected into the atmosphere to a certain height and allowed to fall toward a surface 12. Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according to a predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendant drop of the liquid after a predetermined amount of the liquid has evaporated from the drop.Type: GrantFiled: June 28, 2004Date of Patent: July 4, 2006Assignee: S.C. Johnson & Son, Inc.Inventors: Heather R. Schramm, Edward J. Martens, III, Susan M. Clausen, Padma P. Varanasi, Jesse Ben Crandall

Patent number: 6820821Abstract: The invention is an automated sprayer for spraying the walls of a bath and shower enclosure with a cleanser. The sprayer has a housing that can be mounted inside the shower enclosure and that defines a tray in which an inverted bottle of cleanser is stored. The bottom of the tray has a tube extending downwardly along a longitudinal axis through which the cleanser can pass. A motorized head disposed beneath the tube can be rotated about the axis for metering cleanser from the bottle and spraying cleanser outward. The sprayer includes timer circuitry that delays commencement of a spray for a set time and automatically stops spraying after a predetermined period. The sprayer also includes a system for signaling the beginning of a spray cycle including audio and visual alarms. An automated method of cleaning the shower enclosure is also disclosed.Type: GrantFiled: November 16, 2001Date of Patent: November 23, 2004Assignee: S.C. Johnson & Son, Inc.Inventors: Brian K.

Patent number: 6789741Abstract: An orifice plate is vibrated up and down at high frequency while liquid is delivered to its lower surface so that the liquid is ejected up from the plate in the form of very small diameter droplets. The upper surface of the plate is constructed to resist wetting and buildup of a liquid film thereby to form smaller diameter liquid droplets which are ejected to greater heights. The upper surface of the plate may be treated with a surfactant such as a flurosurfactant.Type: GrantFiled: March 27, 2002Date of Patent: September 14, 2004Assignee: S. C.
