20140093676 | Towels of Micro fibers of Polyester/Polyamide Bi-components and the Method of Making - A fabric with polyester/polyamide bi-components micro fibers may include a wrap knitted double-sided base fabric with polyester/polyamide bi-components micro fibers that is treated by a chemical splitting process. Both sides of the double-sided base fabric may have at least 10 loop piles per square centimeter. Each loop pile may have at least one single thread loop. The bottom of the loop piles may be connected to the base fabric. The loops may be arranged orderly to form a planar structure that has the feature that the loop piles on one side of the base fabric may have plush-like structures at the top sections. The loops may be fractured by sanding the loops with a sand paper of 200-600 grit at about 1/10 to 5/10 of a thickness of the loop piles to form the plush-like structures. | 04-03-2014 |

20110209866 | CORRUGATED SETTLING CUP AND A MULTI-CUP UNIFORM FLUX GAS ANCHOR - The present invention discloses a corrugated settling cup and a multi-cup uniform flux gas anchor, which belong to oilfield gas-liquid separation devices. The external profile of the cup body of the corrugated settling cup rises in a corrugated shape along an axial direction of the corrugated settling cup, which facilitates rapid aggregation and rise of gas. The multi-cup uniform flux gas anchor is comprised of a plurality of the corrugated settling cups, and further includes a central pipe, a plurality of settling cup protectors and a well-flushing valve, wherein the plurality of settling cup protectors are slipped onto the central pipe in clearance fit and the plurality of the corrugated settling cups are slipped onto the central pipe in clearance fit between every two settling cup protectors, a plurality of liquid inlet holes are located evenly on the central pipe at a position close to an inner bottom of each corrugated settling cup, and a lower portion of the central pipe is connected to the well-flushing valve. With the plurality of the corrugated settling cups, the gas anchor divides a gas-liquid mixture into a number of portions, and the external profile rising in a corrugated shape allows the separated gas to rapidly aggregate and rise up, thereby achieving the object of performing effective gas-liquid separation, increasing pump efficiency and oil production, saving energy and reducing consumption. | 09-01-2011 |
