Patent number: 6230444Abstract: The technique of the present invention for minimizing the floor-to-ceiling temperature gradient of a room containing a ceiling, a floor, walls and at least one door and one window, includes the utilization of a phase change material adjacent the ceiling surface and a phase change material adjacent the floor surface. In order to effectively minimize the floor-to-ceiling temperature gradient of the room, first and second phase change materials may be either the same or different, or may be blends of phase change materials. Most preferably, the melting temperature of the first phase change material adjacent the ceiling is greater than the crystallization temperature of the second phase change material adjacent the floor. Preferably, the melting temperature of the first phase change material is 25° C. plus or minus 1° C. and the crystallization temperature of the second phase change material is 22° C. plus or minus 1° C.Type: GrantFiled: May 5, 1999Date of Patent: May 15, 2001Assignee: Outlast Technologies, Inc.Inventor: Barbara Pause

Patent number: 5955188Abstract: A composition for saturation of preformed, previously cured foam substrates having an at least partially open cell configuration, includes a polymer binder in which microspheres containing a phase change material are dispersed. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated.

One method of applying the binder with dispersed encapsulated phase change materials is by applying a binder/microsphere dispersion to the upper surface of a previously cured foam sheet with, then drawing a vacuum from the underside of the cured foam sheet to permeate from 20% to 100% of the cured foam sheet with the binder/microsphere dispersion. The resulting product is then cured.Type: GrantFiled: October 2, 1998Date of Patent: September 21, 1999Assignees: Outlast Technologies, Inc., R.H. Wyner Associates, Inc.Inventor: Robert J. Pushaw
