Abstract: A method of forming a roofing-grade asphalt mixture can include mixing a bio-asphalt including a partially oxidized bio-source material, a bitumen source material different from the bio-asphalt, and particles to form the roofing-grade asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 102° C. and a penetration distance no greater than approximately 20 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104° C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 177° C., or any combination thereof. The roofing-grade asphalt mixture can be applied to a base material to form a roofing product.

Abstract: An air diffuser having a single air inlet has air outlets straddling a wall of a structure to distribute air to two or more rooms of the structure. The air diffuser includes an adjustable baffle that selectively directs air toward the first and second rooms. The air diffuser includes an acoustic dampener that prevents sound from moving through the air diffuser from one room to the next.

Abstract: A mounting assembly for a small portable computer provides both a housing to receive the computer and releasably attach it to a vehicle steering wheel and connections for supplying electrical power to the computer, with that housing also providing a pivotally movable upper lid which may be closed to cover and protect significant portions of the computer and may be opened to provide for access to the computer.
