| 20090235914 | HEATING SYSTEM AND APPARATUS - A heating apparatus and a system that utilize friction to generate thermal energy. The heating apparatus comprises a housing unit, a plurality of heating chambers for generating heat, an actuating unit, a shaft; and at least one blade unit. Each heating chamber comprises a stationary disc member, a rotating disc member, and a medium disposed between the stationary disc member and the rotating disc member. The actuating unit drives the rotating disc member in the heating chamber to generate thermal energy by friction among the stationary disc member, the rotating disc member, and the medium. Thermal energy generation is controlled by rotating speed, diameter of the disc member, and contact pressure between the rotating disc member and the stationary disc member. Tube members can also be used in the heating chambers. | 09-24-2009 |

| 20100284640 | ROLLER BEARING - The invention is characterized by a rolling bearing and tools for its assembly, it being possible for the bearing to have the same external dimensions as conventional rolling bearings. The invention comprises rolling bearings, commonly of ball bearing type, for journaling rotating movements where the rolling elements can be made as spherical balls or rollers or any other form of rolling element that is advantageous. The invention also comprises a method for mounting of rolling bearings, commonly of ball-bearing type, for journaling rotating movements where the rolling elements can be spherical balls, rollers or any other form of rolling element that is advantageous. The mounting is effected by means of sleeves which are given a fork-shaped design. | 11-11-2010 |

| 20090075557 | Toy Illumination with Music - An illuminated toy is disclosed herein. In various aspects, the toy has a body, and may have one or more wheels rotatably thereto such that the body may rest upon the one or more wheels and may be conveyed about by the one or more wheels. The toy includes a sound module adapted to generate sound, and a light source is located about the body. The light source cooperates with the sound module to emit light in coordination with the sound generated by the sound module. For example, the light source may be switched on and off in coordination with the beat of sound in the form of music. | 03-19-2009 |
