20150152726 | INFORMATION TRANSMISSION APPARATUS FOR LOGGING WHILE DRILLING - An information transmission apparatus for logging while drilling comprises a hollow drilling rod and at least one cable. The drilling rod comprises at least one first drilling rod member and at least one second drilling rod member spliced to each other alternately. The first drilling rod member comprises a through hole, and the second drilling rod member comprises a stepped hole. The cable comprises a fixed end, a connected end, and a folded portion connect the fixed end to the connected end. Each of the cables is fixed in the stepped hole through a fixed end or is connected to a connected end of an adjacent cable. The connected end may be stretched along the stepped hole, and stretched through the through hole to be electrically connected to a logging instrument or a fixed end of the adjacent cable. The apparatus provides protection for a cable through a hollow drilling rod, thereby improving the transmission reliability. | 06-04-2015 |

20150297474 | A METHOD FOR PREPARING ROUND EMULSION BEADS USING LOW TEMPERATURE COOLING AND THE PRODUCT THEREOF - The present invention relates to a method for manufacturing solid round emulsion beads by dropping liquid emulsion into a cryogenic freezing refrigerant. The obtained solid round emulsion beads can be stored and used at a low temperature. The solid round emulsion beads can be coated with a solution containing a composition which is solid at room temperature or which can form gel. The emulsion beads can be prepared by using liquid emulsion containing additional composition, which is solid at room temperature or can form gel, in the water phase of oil-in-water (O/W) emulsion or the oil phase of oil-in-water (W/O) emulsion. The emulsion beads prepared by the present invention can maintain its shape without swelling and/or damage but with stability and does not give any grainy feeling when the liquid emulsion was applied on the skin. | 10-22-2015 |
