Abstract: Devices, systems, and methods are provided for mixing a compact dual axis centrifugal mixer configured to rotate a receptacle containing a voluminous substance to be mixed about two different axes. The compact dual axis centrifugal mixer may be configured to function as a tabletop mixer. The dual axis centrifugal mixing device of the invention may further include power transmission system adapted to transmit rotational energy produced by a rotary motor to a second rotatable housing allowing synchronous or asynchronous rotation of the second rotatable housing in relation to a first rotatable housing.

Abstract: A milking liner includes an integrated short air tube and short milk tube. In one configuration, the pulsation air is delivered through the bead of the milking liner directly inside the shell through a plurality of outlets. The disclosure also provides alignment features that assist the person assembling a milking liner and shell. The features limit rotation between the liner and the shell. The liner includes a short air tube that extends beyond a short milk tube with each having a sealing bead. The sealing beads are offset from each other.
