DUAL table

Abstract: A milling machine includes a bi-directional, variable speed, rotary workpiece-holding table, a table drive sized to achieve relatively high acceleration and deceleration rates, a cutting tool mounted to a single or dual axis head, and a control system adapted to achieve a high degree of tool position and table rotational position accuracy cooperating to permit high-speed machining operations, including substantially dome-shaped parts characterized by circumferential surface portions interrupted by radial wall portions. A dual table drive and interchangeable head arrangement make the machine also suitable for conventional turret lathe operations.

Abstract: A hydraulically controlled portable dual table with a gate which enables the examination of a calf or a sheep by restraining the animal while the rotatable tables are vertical with neck and body catches of one table. The table and animal are rotated to a horizontal position for examination, branding, dehorning or castration. The table and animal are returned to a vertical position and the neck and body catches released. The second table is employed to restrain the animal with its neck and body catches and lifted to a horizontal position for examination of the other side of the animal. The operation of the hydraulic controls and the examination can be performed by one person.

Abstract: The invention discloses a mixed storage system and a mixed storage method for supporting Hive DML (data manipulation language) enhancement. The storage system is established on the basis of a Dual Table and comprises a Dual Table establishing module and a Dual Table actuating module, wherein the Dual Table establishing module is used for establishing the Dual Table which comprises a main table and a secondary table, maintains unique ID (identification) of each row of data and provides a specific operation set for the external on the basis of a cost model; and the Dual Table actuating module is used for reading and querying data in the Dual Table on the basis of the main table and the secondary table of the Dual Table, changing data in the Dual Table on the basis of the secondary table of the Dual Table, implementing the operation set provided by the Dual Table on the basis of the cost model, and combining the main table and the secondary table when data are read on the basis of the unique ID of each row of ordered data.

Abstract: A separating apparatus has a frame comprised of a stationary lower frame and a tiltable upper frame. A pair of longitudinally independently displaceable tables are spring-biased into respective central positions on the frame and are each displaceable in either longitudinal direction from these central positions. A drive assembly comprises an electric motor operatively connected to a crank pin that is rotated so as to move longitudinally relative to the frame. A link is connected between this crank pin on the front table and the rear table so that the two tables are moved oppositely longitudinally relative to each other when the motor operates. A stabilizer including a two-arm lever pivoted on the frame and having a pair of arms each connected via a respective stabilizing link to a respective table may be provided in the arrangement in order to insure that the strokes of the two tables remain at a fixed ratio to each other.
