Today in 2014, just one year ago, US Patent 8678247 B2 was issued, an invention of Paul Haskayne, Robert W. Shettle, Donald W. Smeller, Jarrell L. Jennings III, and Merrill R. Good, assigned to the Lancer Corporation, for their “Creamy Foam Beer Dispensing System.” Here’s the Abstract:

A creamy foam beer dispensing system includes a coupler removably securable with a keg, a transportation tube, and a faucet having a handle coupled with a plunger communicating with the transportation tube. The handle is movable among a closed position, an open position, and a creamy foam position. In the closed position, the handle maintains the plunger squeezed against the transportation tube such that no beer flows from the faucet. In the open position, the handle lifts the plunger substantially, completely off the transportation tube such that beer flows smoothly from the faucet. In the creamy foam position, the handle lifts the plunger off the transportation tube a distance such that an aperture created in the transportation tube produces creamy foam flow from the faucet.
