| 20080209817 | Diamond polishing disc process - A diamond polishing disc process includes the following steps. First, an adhesive material is coated on outer sides of the woven layer with a plurality of meshes, so as to form an adhesive layer. Next, the adhesive layer is adhered in an accommodation unit. Afterwards, pluralities of diamond particles are implanted in the adhesive layer, and are respectively adhered in each mesh of the adhesive layer. Then, a polymer material is filled into the accommodation unit, so as to fix the diamond particles to the polymer material. Finally, cure the polymer material, and remove it with the diamond particles from the accommodation unit, thus obtaining a diamond polishing disc base with the diamond particles arranged uniformly and having consistent in orientations. | 09-04-2008 |
| 20090075350 | METHODS FOR PRODUCING ALKYL ESTERS - This invention relates to a method for producing an alkyl ester via a transesterification or esterification reaction. The method includes (1) mixing an oil source containing a triglyceride or a carboxylic acid and a first primary alcohol or a first secondary alcohol in a first organic solvent to form a first solution; in which each molecule of the first organic solvent contains 4-8 carbon atoms and a heteroatom; (2) reacting the triglyceride or the carboxylic acid with the first primary alcohol or the first secondary alcohol in the presence of a first lipase to produce a first alkyl ester, in which the first solution does not undergo phase separation throughout the reaction; and (3) separating the first alkyl ester from the first solution. | 03-19-2009 |
| 20090264682 | SYSTEM AND METHOD FOR PREPARING CYCLOALKANONE - A system and a method for preparing cycloalkanone are provided. The method includes the steps of: (a) oxidizing cycloalkane to form a mixture containing ketone, alcohol and unreacted cycloalkane; (b) adding to the mixture alkali metal hydroxide or alkali metal carbonate to form a first mixed solution; (c) separating the first mixed solution into a first organic phase solution and a first aqueous phase solution; and (d) extracting the first organic phase solution by water to obtain a second organic phase solution and a second aqueous phase solution; and (e) distilling the second organic phase to separate out cycloalkanone. The method performs phase separation after a mixing step, and then performs water extraction, thereby effectively lowering the contents of the metal salts in the organic phases. Compared with acid-water extraction, the method not only provides better cooling effects but also reduces equipment corrosion, and therefore has the advantage of decreasing the need for sewage treatments. | 10-22-2009 |
| 20100173370 | Fuel Production - An apparatus that includes a first reactor and a return mechanism. The first reactor has an inlet to receive a mixture comprising a first reactant, a second reactant, a reaction product, and an inert solvent that dissolves at least a portion of the first and second reactants, an enzyme to facilitate a reaction between the first and second reactants to generate more reaction product, and an outlet to output the reaction product, including the reaction product received at the inlet and the reaction product generated from the reaction between the first and second reactants. The return mechanism sends at least a portion of the reaction product from the outlet back to the inlet. | 07-08-2010 |

| 20100186887 | DIES FOR MANUFATURING DIAMOND DISCS - A diamond disc manufacturing process includes the following steps. Firstly, a container is provided, and an adhesion layer is formed in the container. A hollow member having a plurality of meshes is covered on the adhesion layer. A plurality of diamond particles is implanted on the hollow member and embedded into the meshes of the hollow member, so that the diamond particles are adhered onto the adhesion layer. Then, a resin material is infused into the container, so that the diamond particles are bonded on the resin material. Finally, the resin material together with the diamond particles is released from the container, so as to obtain a diamond disc base with the diamond particles having uniform distribution and orientation. | 07-29-2010 |
