Patent number: 4259401Abstract: A building element which inhibits the change of the interior temperature of a building beyond prescribed limits approximating room temperature. A rigid porous matrix structure is provided in thermal communication with the building interior. A store of phase change material impregnates the matrix structure. The phase change material has a melting point within the temperature limits so that the material melts when the interior temperature of the building exceeds the temperature limits. Melting of the material absorbs heat and reduces the interior temperature of the building, until the material is entirely melted. Conversely, the material freezes when the interior temperature of the building falls below the temperature limits to release heat and increase the interior temperature until the stored material is entirely frozen. The store of phase change material is sealed within the matrix structure so that the material undergoes repeated changes in phase between liquid and solid.Type: GrantFiled: November 20, 1978Date of Patent: March 31, 1981Assignee: The Southwall CorporationInventors: Day Chahroudi, Sean R.

The non-woven fabric has a substantial thickness, such as 4-5mm, and is produced by the well-known needle-punching process. This base material is saturated with and covered by the single kind of asphalt. A method of making same comprises feeding said non-woven fabric along a vertical path into a bath of molten asphalt, thereby permitting the air contained within the fabric to successively escape vertically through the fabric itself into the atmosphere while permitting the fabric to be uniformly and completely saturated with said molten asphalt, and then withdrawing said fabric from the molten asphalt into the atmosphere and drying the same.Type: GrantFiled: September 11, 1975Date of Patent: July 12, 1977Assignee: Mitsuboshi Sangyo Kabushiki KaishaInventors: Hajime Iwasaki, Yasuo Tomita

Patent number: T964011Abstract: article provided with a pressure-sensitive adhesive layer composition, which composition is characterized by improved flow resistance at high temperatures (e.g. at 90.degree. C), and which comprises 50-97 parts by weight of a bituminous component dispersed in an extender oil, 3 to 50 parts by weight of at least one thermoplastic polymer, which is preferably a block polymer having the general structure:A--B--(B-A)nwhere A is a monoalkenyl arene block, B is a conjugated diene block, and n is an integer from 1-15, and 5 to 50% by weight (based on the combined weight of the bituminous component and the thermoplastic polymer) of a carbon black having an oil absorptivity of above 80 milliliters per 100 grams. Such articles usually possesses good low temperature flexibility, tack and adhesive strength.Type: GrantFiled: February 28, 1977Date of Patent: November 1, 1977Inventor: Thomas C. Blanken
