Polyurethane Artificial Holloween Pumpkin
US Patent:
6555188, Apr 29, 2003
Filed:
Feb 5, 1998
Appl. No.:
09/019533
Inventors:
Jeffrey A. Chapman - Scottsdale AZ 85251
International Classification:
A41G 100
US Classification:
428 17, 428 21, 428 365, 4283184
Abstract:
The invention is in the field of three-dimensional hollow novelty items and their manufacture, particularly items such as artificial pumpkins that the consumer desires to carve or alter after purchase. A carvable novelty article, such as an artificial Halloween pumpkin, comprises a polyurethane shell substantially surrounding an interior volume and having a thin coating, such as an acrylic elastomer, on the exterior surface of the shell. The carvable article can be formed by an inventive process in which polyurethane foam material, such as material having a nominal density of about 2. 5-3. 0 pounds per cubic foot, is sprayed from a nozzle rotating with respect to the inside of a mold. After the polyurethane foam article and the mold are separated, the article is coated with an elastomeric coating, such as an acrylic material that is applied as a liquid. Thus, the inventive articles, including those made in accordance with the inventive process, can be used as three-dimensional hollow novelty items of a variety of shapes. In addition, the inventive articles, such as Halloween pumpkins, are carvable, reusable, and can be used with a light source.
Air Mass Isolation System
US Patent:
6370905, Apr 16, 2002
Filed:
Jan 23, 2001
Appl. No.:
09/767996
Inventors:
Jeffrey A. Chapman - Fountain Hills AZ 58268
International Classification:
F25D 1704
US Classification:
62404, 62239, 62383
Abstract:
In an exemplary configuration, an air container is placed in a vacant portion of a structure and substantially prevents convection between an air mass in that portion and an adjacent air mass of an occupied portion of the structure. By thus isolating the air masses, the air container restricts heat transfer between them and advantageously allows the occupied portions air mass to heat up and cool down without requiring substantial heating and cooling (at least initially) of the vacant portions air mass. Other methods and structures with different advantageous features are also described.
