Abstract: A paddle mixer for evenly and efficiently mixing a volume of aggregate with minimal spillage is described. The paddle mixer includes a first portion, a second portion, a first paddle, and a second paddle. The paddle mixer may include a means for adjustably fixing the first portion to the second portion. The first paddle and the second paddle are arranged on the first portion and the second portion, respectively, such that the first paddle and the second paddle are perpendicular to each other, promoting mixing of the volume of aggregate with a whirlpool effect allowing mixing with minimal spillage. The first paddle and the second paddle may also be arranged perpendicular to each other by the means for adjustably fixing the first portion and the second portion.

Abstract: A container having a curved bottom and base cup which allows the container to stand upright. The container and base cup are fitted together by a mechanical engagement having portions on the container and base cup. The mechanical engagement of the container is disposed within the bottom cone of the container. The mechanical engagement of the base cup is cantilevered from the bottom of the base cup. Such disposition reduces stress at the interface between the side wall of the container and edge of the base, providing for a smoother transition and better appearance. Also, this disposition provides resistance to separation of the container and base cup during drop impact. The bottom of the container may be curved and have a well therein for receiving the contents of the container and a dip tube.

Abstract: The present invention generally relates to a system and method for manufacturing plastic injection mold cavity components. More specifically, the present invention provides an integrated system and method for manufacturing plastic injection mold cavity components, which integrates manufacturing between two or more subcells. In one embodiment of the invention, a supercell system integrates two or more subcells, in which component workpieces and electrodes are machined. A supercell may include a computerized master control unit, configured to monitor and provide instructions for a master robot that delivers and retrieves workpieces and electrodes to two or more subcells. Thus, two or more subcells may be integrated by the master control unit, the master robot, a track or path that the master robot follows, identification indicia attached to workpieces and electrodes, a combination thereof or any other components of supercell that may suitably integrate two or more subcells.
