A modular bar made of bar modules includes a bar element and one or more seating elements pivotably attached to the bar element. The seating element(s) is moveable relative to the bar element between a stowed position and a seat position, the module configured to be arranged adjacent one or more other bar modules to form a bar.

An example system for deployment of a compacting head in a waste compartment includes an eutectic alloy fusible link positioned within a waste compartment that breaks at or above a predetermined temperature, a spring tensioned deploy lever that is deployed based on a break of the eutectic alloy fusible link, a pivotal joint assembly that collapses based on deployment of the deploy lever, and a compacting head of a trash compactor that is deployed to compact contents of the waste compartment based on collapse of the pivotal joint assembly.

A galley cart has a rear wall with an inlet port and an outlet port. A first divider has a first edge, wherein a first distance is defined between the first edge and a front wall. A second divider has a second edge, wherein a second distance is defined between the second edge and the front wall. The second distance is less than the first distance for control of the flow of cooling air.

Described are inerting systems that may be used on board an aircraft or other passenger transportation vehicle to reduce a risk of fire due to electronic components or to other elements in a compartment and to assist in preventing or extinguishing any fire or hazardous condition that may occur. The systems include a source of inert gas such as oxygen depleted air generated from a fuel cell on board the aircraft. The oxygen depleted air or other inert gas is conveyed through ducts to compartments that house the electronics, thus changing the conditions in the compartment to be less conducive to fire.

This invention relates in general to a system for treating hard water encountered in aircraft potable water equipment; such as hot water heaters and, more particularly, to the prevention of scale deposits in aircraft lavatory and galley heated water system components by installing a unique scale reduction system. The scale reduction system generally comprised of a housing with a modular cartridge inserted therein. The cartridge is porous and contains a chemical composition within its inner cavity, and this chemical composition is mixed with untreated inlet fluid flow so that the outlet flow is of a sufficiently diluted concentration. Various chemical compositions may be utilized to counteract any number of conditions that affect potable water equipment and, in one embodiment, a water softening agent is utilized to combat scale build-up in aircraft plumbing.

A lift system for an aircraft includes a first galley cart, a second galley cart, a floor deck, and a frame. The frame defines a first storage zone, a second storage zone, and a third storage zone that are stacked. A bottom end of the first storage zone is aligned with the floor deck, a top end of the second storage zone is aligned with the floor deck, and a bottom end of the third storage zone is aligned with a top end of the first storage zone. The lift system also includes a first lift configured to move the first galley cart from the first storage zone to the second storage zone and a second lift configured to move the second galley cart from the first storage zone to the third storage zone.

An oven may include inner oven walls defining a cavity. The oven may further include a heating element configured to heat air in the oven. The oven may further include a fan positioned between the rear of the oven and the heating element. The fan may be configured to: draw air from the front of the oven to the rear of the oven; blow the drawn air over the heating element to produce heated air; and distribute the heated air within the oven.

An automatic drain system may comprise a drain including a neck defining a drain orifice and a flange extending from the neck. A liquid detection sensor is located on at least one of the neck or the flange. A sink assembly may comprise a sink basin and the drain located in a sink opening formed in the sink basin.
