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: An adaptive input/output (I/O) scheduler for storage arrays is disclosed. In one embodiment, a method of a redundant array of independent disks (RAID) controller for deploying an optimal I/O scheduler type per a storage array configuration includes generating performance data by assessing respective performances of a plurality of I/O scheduler types on different RAID level test volumes with at least one I/O pattern generated internally within a storage subsystem which comprises the RAID controller. The method also includes storing the associativeness of the performance data with respect to a particular I/O scheduler most suited for a given I/O workload to a nonvolatile memory of the RAID controller. The method further includes deploying an optimal one of the plurality of I/O scheduler types and at least one performance parameter for at least one subsequent I/O operation associated with the storage subsystem based on the performance data.
