Abstract: Embodiments of the invention are directed to a beverage mixing apparatus which may be used to prepare alcoholic or non-alcoholic beverage combination cocktails. In one embodiment, the beverage mixing apparatus includes an upper assembly capable of supporting a plurality of tapered vessels having a first size and a lower assembly capable of supporting a plurality of tapered vessels having a second size. The upper assembly includes a handle assembly which functions like a plunger to submerge and release the plurality of tapered vessels having a first size into the plurality of tapered vessels having a second size when force is applied thereto.

Abstract: The present invention concerns itself with methods and systems for just intonation tuning of a digital/electrical piano in real time. A simple and economical solution is presented, which makes use of a PLC (i.e., Programmable Logic Controller), having 13 inputs (an octave plus one input for the pedal) and 22 outputs (22 possible frequencies per octave), relays, and parallel connections between octaves and PLC inputs, as well as, between PLC outputs and relays.
