Abstract: A nanometer heat-conducting water solution for use in a car cooling system is disclosed. The nanometer heat-conducting water solution is formed by mixing a AlO2 solution (1.1 vol %) having 3-10 nanometer scale materials with a TiO2 solution (1.1 vol %) having 3-10 nanometer scale materials, wherein the obtained solution is then mixed with a diluent (93 vol %), and dispersing agents (3.43 vol %) and an emulsifying agent (1.37 vol %) are thereafter added so as to disperse the AlO2 solution and the TiO2 solution in the diluent uniformly. When the obtained stable nanometer heat-conducting water solution is added to a water tank of the car, the TiO2 cleans limescale and the emulsifying agent adheres to wall surfaces of water jackets to allow AlO2 to release energy continuously. Moreover, the nanometer scale materials speed up the micro-explosion of the cooling water so as to optimum the cooling effect and increase the heat-dispersing efficacy significantly.

Abstract: A bicycle chain transmission, comprising a pedal link adjustably fastened in a holder plate mounted on the outer side of a chain wheel and connected with a side projection of a bearing block which is mounted on an eccentric sleeve at the bottom of a bottom bracket bearing axle of a bicycle. The eccentric motion of the eccentric sleeve forces the bearing block to rotate eccentrically so as to squeeze the pedal link to adjust the length of its arm of force according to its angle position relative to the chain wheel, so that reduced labor consumption in pedaling can be achieved.
