Abstract: This invention is about the fastening belt with freely rotatable drag hooks, which includes two drag hooks. The said drag hooks have an upper cover and a bottom cover, with the hook fixed in the front of the drag hooks; one elastic rope to link the two drag hooks, which is made from stretchable material. Two rotatable linker and two ends of elastic rope are fixated inside the rotatable linker. The rotatable linker is connected with the rear rotation of the drag hook. The hook and the elastic rope are linked by the rotatable linker and the drag hook is linked with the rotatable linker. Thus, the drag hook can rotate freely in the elastic rope. The rope does not kink when in use, which not only prolongs the life of elastic ropes, but also reinforce the reliability of the connection between the drag link and the elastic rope.

Abstract: An anode refinement method for high-sulfur content coarse copper: while high-sulfur coarse copper liquid from a flash converting furnace flows to the anode furnace through a chute, inert gas is continuously added, to stir the copper liquid and improve discharging of the SO2 produced from reaction of the sulfur with oxygen in the liquid and the oxygen absorbed from the atmosphere, so as to remove more than 90% sulfur in the coarse copper liquid. After the coarse copper liquid is fully led to the anode furnace, operations of low-oxidization and low-reduction, non-oxidization and low-reduction or cancel of reduction-oxidization are conducted according to the sulfur content in the copper liquid. The method can resolve the shortages in the fire-refining process, save working time, notably improve production efficiency and capacity, save energy, and settle the pollution problem of black smoke in the atmosphere.

Abstract: This invention relates to the technical area of sports and recreational apparatus, which reveals the dual-purpose and turnover ping-pong table. This dual-purpose table includes the table support and table surface, two sides of which are different tables. The center of short frame on both sides of the table surface hinges the baffle means on the upper end of the table support through the pivot components. Its characteristics lie in that the baffle means on the upper end of table support is equipped with the positioning device for table surface turning over, which has a stand bar that can be turned around. The stand bar can withdraw if the table surface needs turning around so that the table surface turn over. When the table surface has turned around, it can stretch out below the surface and stabilize the table surface. The structure is very simple and convenient for application.

Abstract: A method of casting a base of high-power wind turbines with low-temperature nodular graphite iron, using furan resin sand as the mold sand and having no risers or chills in the mold. The mold undergoes microseismic compaction and has no chills risers. The parting face of the mold is perpendicular to the ground. The molten iron in the mold is solidified evenly. Therefore, shrinkage holes and disperse shrinkages base are reduced greatly and the dregs and air are discharged easily for the base. The pouring system designed together with a reasonable pouring rate and time make the filtering system useful for blocking dregs.

Abstract: A method and device for making clients rapidly access to the peer-to-peer network comprise that the accessed clients, which are separated into one or more normal state groups; the clients that intend to log in are separated into one or more login groups; and the required contents, the variant of the contents or the content-related information are selectively transmitted to the members of the login groups immediately. After a certain login group becomes stable, the normal state groups which the login groups intend to be added into are selected and each member of the login groups is added into the selected normal state groups. In this invention, there is no need to frequently send notification individually when each client loges in, rather than send group notification, thus it can reduce network dithering, at the same time the user can receive the content or the related variant of the content immediately and watch the playing of the content without any wait when accessing to the network.
