Abstract: A corkscrew includes a rotatable pinion gear having a fixed radius and a horizontal rotational axis rotatably coupled to a shaft and engaging a gear rack of a vertically translating driver. A helical worm is coupled through a freely rotating connection to the vertically translating driver wherein the corkscrew freely rotates about a longitudinal rotation axis coaxially aligned with a location of a bottle neck from which a corkscrew is to be withdrawn. A crank rotates the pinion gear for translating the driver up and down relative to the shaft along the rotation axis of the corkscrew. A helical pinion gear a helical pinion rack drives rotates about the longitudinal rotation axis in meshing engagement with helical rack on the vertically translating driver, the helical pinion gear having at least one blade to contact the bottle neck scoring a foil capsule thereon as the helical pinion gear rotates.

Abstract: A method and apparati for regulating introduction of ambient air begins with initiating a liquid flow through a venturi to induce a localized drop in pressure at a bowl situated at a venturi throat. Airflow is admitted at a barrel inlet, through a first barrel lumen segment to a first half-moon port at a throttle first side. The airflow is selectively obstructed by a second half-moon port whose rotational position relative to the first half-moon port defines a variable aperture. The airflow is conducted from the second half-moon port through a second barrel lumen segment to the barrel outlet and mixing with the liquid to produce an aerated liquid.

Abstract: In a system for imparting visually identifiable distinctions between individual drinking vessels, an identification helix is used to impermanently attach to an elongate element of at least one of the drinking vessels. At least two identification helices are provided for engaging an elongate element of a drinking vessel such as a stem or handle. The system of identification helices comprises a first helical member of resilient flexible material having a pair of ends and adapted to engage the elongate element by wrapping the elongate element with a generally encircling geometry. A second helical member of resilient flexible material has, as well, a pair of ends and adapted to engage the elongate element by wrapping the elongate element with a generally encircling geometry. The second helical member is visually distinct from the first differing in one of a group of qualities consisting of handedness, color, color combinations, and attached charms.

Abstract: A corkscrew includes a rotatable pinion gear having a fixed radius and a horizontal rotational axis rotatably coupled to an annular collar and engaging a gear rack of a vertically translating driver. A helical worm is coupled through a freely rotating connection to the vertically translating driver wherein the corkscrew freely rotates about a longitudinal rotation axis coaxially aligned with a location of a bottle neck from which a corkscrew is to be withdrawn. A crank rotates the pinion gear for translating the driver up and down relative to the collar along the rotation axis of the corkscrew. A helical pinon gear a helical pinion rack drives rotates about the longitudinal rotation axis in meshing engagement with helical rack on the vertically translating driver, the helical pinion gear having at least one blade to contact the bottle neck scoring a foil capsule thereon as the helical pinon gear rotates.
