Abstract: A vent valve flow fuse includes a valve cap with a valve cap cavity defined by one or more valve cap interior surfaces. The vent valve flow fuse includes a valve body with a valve body cavity defined by one or more valve body interior surfaces. The vent valve flow fuse includes a poppet configured to at least partially fit within the valve cap cavity and the valve body cavity. The vent valve flow fuse includes a spring configured to fit within the valve body cavity and to generate a resistive force against the poppet. The poppet is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity from a vent valve and engages the poppet. The poppet is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity and engages the poppet.

Abstract: A brew head assembly insertable within a brewing apparatus dimensioned to fit within a compartment in a galley of an aircraft may include an adjustable assembly and a brew cup. The adjustable assembly may include a brew head and a support member. The support member may define a first brew head cavity. The brew head may be at least partially inserted into the first brew head cavity. The adjustable assembly may be actuatable between an open position and at least one closed position. The brew cup may define a second brew head cavity. The brew head may be at least partially inserted into the second brew head cavity. A height between the brew head and the brew cup when the adjustable assembly is in the at least one closed position may be responsive to one or more parameters of a brew pod of a plurality of brew pods.

Abstract: An adjustable brew head linkage includes a brew head linkage element, a handle linkage element, and an adjusting element between the brew head linkage element and the handle linkage element to smoothly increase and decrease the distance between the brew head linkage element and the handle linkage element to alter the size of a corresponding brew chamber to accommodate various brew pods. The brew head linkage element and/or handle linkage element may include a threaded portion to engage the adjusting element. Turning the adjusting element causes deflection. Threaded portions may have opposite handedness or different pitches. A secondary brew head linkage locking element provides friction to lock the adjusting element in place. The adjusting element increases and decreases the distance between the head linkage and the handle linkage in increments smaller than 0.178 millimeters ( 7/1000 inches).

Abstract: A multi-position shuttle valve assembly includes a housing with at least one flow path and a shuttle. The at least one flow path is configured to receive steam from a froth heater of an aircraft brewing apparatus. The at least one flow path is configured to direct the steam to the defined cavity. The shuttle is configured to divert the steam to a froth wand when the shuttle is in a first position. The shuttle is configured to divert the steam to a froth module installed on the housing when the shuttle is in a second position. A translation of the shuttle between the first position and the second position is dependent on the froth module being installed on the housing.

Abstract: The present invention is a froth wand for an espresso machine that can generate a high velocity stream of steam to foam a beverage at the beverage brewing apparatus. The wand includes an adapter for attaching to the beverage brewing machine at a steam supply outlet, and a conduit for communicating the steam to a steam tube. The steam tube has a cylindrical body with an annular recessed exit, and is surrounded by a cylindrical sheath. The sheath includes a cylindrical plug with a small longitudinal aperture that fits into the outlet of the steam tube. The mating of the sheath's plug and the steam tube forces the steam through the aperture, accelerating the steam at the exit.

Abstract: The present invention is a beverage brewing apparatus for an aircraft galley that includes a stow away platen to support a coffee cup or mug during brewing and that can be withdrawn when not in use to eliminate the intrusion of space in the galley if the platen were not stowable. The platen can operate like a pull out drawer, extending from its designated cavity when needed and pushed back into a withdrawn position when finished.

Abstract: The electro-optic liquid level sensing system detects a level of liquid in a container having an upper opening, such as for a server container of a beverage maker for a transport system, such as for aircraft, trains, trucks, buses and the like. A support housing mates with the upper opening of the container, and a primary liquid level sensor is mounted in the support housing for non-intrusively measuring the liquid level. A secondary liquid level sensor may be mounted in the support housing to sense a predetermined liquid level to prevent accidental overflows. Protective lenses may be placed in front of the primary liquid level sensor.
