Abstract: An apparatus for cutting bean curd into pieces of the fixed size and packing them. This apparatus does automatically: the transporting, cutting and packing of bean curd under water in a water tank. Therefore, this apparatus requires no manual operation, is sanitary, involves high production capacity and is free from production of bean curd of broken shape.

Abstract: Disclosed is a method and apparatus comprising a side drive system with a drive shaft (24, 24a) driven from the platform level (10) and powering a drilling unit (16) for rotating drill pipe (14). Except for the tethering of the drive shaft at the top of the derrick (60-64) and its coupling to a power source (70) at the platform level, there is preferably no stabilizing means for the system. The drive shaft (24, 24a) is stationary, preferably hollow, and extends the height of the derrick located to one side of the main drilling axis. The power source (70) at the platform level comprises a power takeoff from a conventional rotary table (84). The upper drive assembly (18) of the drilling unit (16) is coupled to the drive shaft (24, 24a) and capable of vertical movement along the drive shaft and providing torque to the drill string.

Abstract: A mat board cutter in which a cutter-carrying body has an end-to-end slot that affords adjustment by screws extending across the slot to bring bearing surfaces on the body into close-fitting relatively slideable engagement with a guide rail on which the body is slidably mounted.
