  • Patent number: 7922811
    Abstract: Compositions and methods for increasing grinding efficiency of cement, cement clinker, raw materials for cement, and other inorganic particles. Use of biomass-derived polyols such as diols, triols, or mixtures thereof, optionally with a conventional grinding aid, cement quality improver, and/or hexavalent chromium reducer, are believed to provide less risk of sludging when compared to glycerides obtained from fossil fuel sources.

  • Patent number: 7924175
    Abstract: Disclosed in a wearable electronic device including an optical keypad supported by a keypad housing. The optical keypad may include a plurality of keys disposed along the keypad housing, and a plurality of illumination sources and optical receivers with a corresponding illumination source and optical receiver for each of the plurality of keys. The keypad signal interface may be limited to three connections, to provide a connection for power, a connection for ground, and a connection for data between the keypad housing and the main housing. The electronic device may also include at least one optical receiver configured to be optically coupled to at least one of the plurality of illumination sources, and configured to convert a received optical signal representing data into an electrical signal representing data. The illumination sources may provide optical signals during key presses, and may in addition provide key illumination for unpressed keys.

  • Patent number: 7900856
    Abstract: A sorting member with an optimized surface shape is adopted to pressurize a mixture heated on the sorting member to allow a melted resin mixed in the mixture to adhere to the sorting member to sort the resin from an unmelted resin. Thus, resin materials are sorted and recovered from unwanted home electric appliances and the like at a high purity.

  • Patent number: 7892353
    Abstract: Methods and compositions for grinding materials are provided. In an embodiment, the present invention provides a method of grinding solid materials. For example, the method can comprise mixing the solid material with the grinding aid, and using a grinding media such as steel balls to grind the solids. The grinding aid composition can comprise one or more glycerin by-products derived from a biodiesel manufacturing process. The grinding aid composition can also comprise one or more glycerin by-products of transesterification reactions involving triglycerides. The grinding aid can be added to the grinding process as a solution.

  • Patent number: 7891590
    Abstract: Method for reusing bituminous products (11), in particular bitumen containing roofing materials and membranes, wherein the bitumen containing products are placed in a second hopper (9), where a particulate material having a grain size between 5 mm and 35 mm is placed in a first hopper (5), and that in the bottom of the second hopper, conveyor means (10) urges the bituminous material into a mixing chamber (8), and that inside said mixing chamber a milling and/or crushing wheel (14) is arranged, which wheel engages and crushes/mills the material transported from the second hopper in an engagement zone, and at the same position as the wheel engages the bituminous material, the particulate material by means of a first conveyor (7) is fed into the engagement zone, and that the wheel's action will fragment the materials and at the same time mix the fragmented bituminous materials and the particulate materials, and transport the material past a sieve (15), where material having a particle size smaller than the sieve

  • Patent number: 7886996
    Abstract: A raw material is fed through a raw material supply channel into a raw material introduction part between a fixed grinding disc and a moving grinding disc. The moving grinding disc is provided on a drive shaft and the gap between the same and the fixed grinding disc is adjusted by means of a gap adjusting mechanism. Heat transfer from the drive unit is prevented while power is transmitted to the drive shaft to rotate the moving grinding disc. The raw material while being transferred through the coarse grinding distributing channel is coarsely ground and any raw material of low grindability is crushed by the crushing part, distributed to the microgrinding part and microground to thereby attain the production of ground matter.

  • Patent number: 7878430
    Abstract: Blending methods for adding and uniformly mixing a small fraction of relatively small particles (additives) to a bulk particulate powder of larger size than the additives. In particular, the present invention provides blending methods for adding and uniformly mixing a small percentage of flow/fluidization additives into fine powders, especially fine paint powders. The fine powder and additives are first pre-mixed for macro-scale homogeneity and then further mixed at a micro-scale (such as with a screen mixing process) for micro-scale homogeneity. With these methods, optimum dispersions and maximum functionalities of additives can be obtained and the disadvantages caused by severe agglomerates of additives can be avoided.
