  • Patent number: 5941636
    Abstract: A mixer is composed of a base, a drive shaft, a plurality of blade seats and mixing blades. The base is engaged with the opening of a liquid container and fastened with a circular body which is fitted over the drive shaft such that the drive shaft is slanted in the liquid container. The blade seats are fastened at an interval with the drive shaft and provided with a pivoting slot in which the mixing blade is fastened pivotally. As the drive shaft is driven by a power source to revolve, the mixing blades are caused to expand by the centrifugal force so as to bring about the mixing effect.

  • Patent number: 4153374
    Abstract: Disclosed is improved homogenizer apparatus of the type capable of operating in the range of 60,000 revolutions per minute. A motor is mounted to a motor support frame structure which in turn is mounted to the cabinet of the homogenizer. Two shafts are mounted to the motor mounting frame and extend downwardly essentially parallel to a spindle operably connected to the motor. A lower flask base support and an upper flask clamp are mounted for sliding movement on the two shafts and clamps formed of a cylindrical member fabricated of a metal softer than the shafts to avoid marring or damage to the shafts are utilized to clamp the flask base and flask clamp in any desired position on the shafts. By attaching the shafts directly to the motor support frame, the flask base and flask clamp remain properly oriented and aligned with respect to the spindle irrespective of shipping and operation vibrations and other external forces.
