An apparatus configured for mixing the contents of one or more fluid containers includes a fluid container support platform configured to hold one or more fluid containers. The fluid container support platform is configured to index the container to one or more specified locations and to be moved in an orbital path about an orbital center independently of the rotation about the central axis of rotation. The apparatus further includes an indexing drive system configured to effect indexing movement of the container support platform and a vortex drive system configured to effect powered orbital movement of the container support platform about the orbital center. An evaporation limiting insert placed within containers reduces exposure of the fluid contents of the container to atmospheric air, thereby reducing susceptibility of the fluid contents to evaporation.

A system and method for easily operated self-releasing stopper/cork for bottles of compressed liquids. The corks have a gas bladder that is designed to be inserted in a bottle and inflated, the bladder having a ribbed or smooth exterior to complete the sealing of the bottle whereby a gas release mechanism can be activated by depressing a button on a cap or via an on-board micro controller and/or electro-mechanical release solution in the cap. Once the gas is released from the top of the bladder the pressure inside the vessel will collapse the bladder's bottom and eject the cork assembly from the bottle.

A stirring device includes the following. A rotating holder is capable of performing a rotating operation in a state where the rotating holder holds a cartridge that accommodates a liquid agent in which a solute is precipitated in a solvent by the liquid agent being left still. A drive motor causes the rotating holder to perform the rotating operation. A posture controller corrects a stop position of the rotating holder to position the cartridge in a first posture in a case where an operation of the drive motor is stopped in a state where the cartridge is in a second posture that is different from the first posture. The first posture is a state in which the cartridge is in a normal stop posture.

A mixing attachment for use with a reciprocating mechanism of a reciprocating hand tool, to quickly and efficiently mix contents of paint cans or other containers, may include a support member and one or more retention ring assemblies. The support member may be disconnectably connected to the reciprocating mechanism. The one or more retention ring assemblies may be attached to the support member. The retention ring assemblies may be mounted in a longitudinal slot on the support member and include an adjustable band and a securing mechanism for tightening the adjustable band about an outer surface of a paint can.

The disclosure is directed to a sample preparation apparatus for grinding or homogenizing test samples. More specifically, the disclosure relates to grinding samples using rotational and linear motion. Grinding samples can be accomplished with an apparatus with a slider-crank mechanism that is attached to an oscillating connecting linkage. The amplitude of oscillatory motion can be greater than or equal to a length of a sample processing chamber.

A vibration mixer suitable for a cartridge having a longitudinal axis and containing a multi-component material, preferably a two-component material, stored in at least two separated chambers inside the cartridge; the vibration mixer including a cartridge holder and a drive for the cartridge holder; the cartridge holder is configured for receiving and locking only one end of the cartridge and is configured for maintaining the longitudinal axis of the cartridge on the cartridge holder in a vertical position.

Disclosed herein are devices, apparatuses, and methods for generating a reciprocating motion for the purpose of grinding or homogenizing samples. An apparatus includes a connecting linkage that extends along a longitudinal axis. The apparatus includes a sample vial holder attached to the connecting linkage. The apparatus includes a crank operatively connected to the proximal end of the connecting linkage, the crank configured to impart rotational motion to the proximal end of the connecting linkage. The apparatus includes a sliding carriage operatively connected to the distal end of the connecting linkage, the sliding carriage configured to restrict the distal end of the connecting linkage to a linear path. The apparatus includes a motor operatively connected to the crank to rotate the crank such that the sample vial holder, in use, moves with a combination of rotational and linear motion.

A system and method for mud mixing using a container to hold a joint compound and the water. The container having a lid to keep the container shut and preventing the liquids from escaping wherein the container may then be shaken by the user to mix the joint compound with the water. The user then may remove lid and pull on a rod and plate connected to one another at the bottom of holding container. Rod and plate act as a pressure seal, whereby when the rod is pulled all of the mud may be removed from the container and placed into a pan for use.

A mixing apparatus containing a drive unit having a drive and a shaft that is pivotable about a pivot axis and is operatively connected to the drive. A pivotable receptacle is arranged on the shaft, where the pivot axis is oriented essentially horizontally, and the pivotable receptacle has a base plate and at least one retainer spaced therefrom, and the pivotable receptacle is configured in such a way that holders for containers can be inserted between the base plate and the at least one retainer in the direction of the pivot axis.
