Abstract: Seating arrangements for seats configurable between an upright and lie-flat position are presented. A three-seat grouping can include a lower aft-facing seating assembly, an upper seating assembly, and a lower fore-facing seating assembly in which the lower seating assemblies underlap the upper seating assembly when in a lie-flat position. Lower seats can be aligned or angled with respect to an upper seat in a manner that conserves space. A six-seat grouping can include 3-seat groupings in which lower seats are aligned with upper seats, or are angled with respect to them. Support structures can be shared by adjacent seats. A six-seat grouping can be embodied as a hybrid arrangement in which footspace is narrower for a lower opposing seat than for a lower seat facing the same direction as an upper seat. In an example embodiment, footspace can be divided between an upper seat and a lower opposing seat.

Abstract: A fastening arrangement for fastening a storage container in a compartment of an aircraft galley comprises a latching mechanism including a latch and a first biasing mechanism, the first biasing mechanism being adapted to bias the latch into a latched position in a first operational state of the latching mechanism, such that the latch is adapted to interact with the storage container upon insertion of the storage container into the compartment of the aircraft galley so as to be moved from its latched position into an unlatched position against the biasing force applied to the latch by the first biasing mechanism, and such that the latch is adapted to be moved back into its latched position by the biasing force applied to the latch by the first biasing mechanism when the storage container has reached a predefined position in the compartment of the aircraft galley.

Abstract: There is disclosed a technique for controlling at least one amplification stage, comprising: selecting a linearity objective for the amplification stage; in dependence on an input signal to said amplification stage, determining a combination of supply input and bias input for the amplification stage in order to meet said linearity objective; and in dependence on there being more than one combination of supply input and bias input for meeting the linearity objective, selecting the combination that optimises a further system performance objective for the amplification stage. The further system performance objective may be one or more of: an efficiency objective; an envelope signal bandwidth objective; or a robustness to production tolerance objective.

Abstract: There is disclosed a multi-stage amplifier comprising: a first amplifier stage; a second amplifier stage; a first voltage supply stage arranged to provide a supply voltage to the first amplifier in dependence on an average power of a signal to be amplified; and a second voltage supply stage arranged to provide a supply voltage to the second amplifier in dependence on an instantaneous power of a signal to be amplified.

Abstract: A mounting system (10) for attaching a box (14) in a compartment (12) of an aircraft galley comprises a first guide device set up for engaging with a complementary second guide device designed on the box (14) when the box (14) is inserted into the compartment (12) of the aircraft galley, and further set up for securing the box (14) against movement in the compartment (12) of the aircraft galley in a direction (P) perpendicular to a longitudinal axis (L) of the compartment (12) of the aircraft galley when the device is engaged with the complementary second guide device designed on the box (14). The mounting system (10) further comprises a locking mechanism set up for securing the box (14) against movement in the compartment (12) of the aircraft galley in a direction parallel to the longitudinal axis (L) of the compartment (12) of the aircraft galley.

Abstract: The invention relates to a transport cart (10) for loading an aircraft galley, comprising a base element (12) and a plurality of wheels (14) attached to the base element (12). Two frame elements (20, 24) are connected to the base element (12) and disposed at a distance from each other. A first guide device (28, 28?, 28?) is set up for engaging a complementary second guide device formed on a box that is receivable in the aircraft galley to be loaded and for transporting on the transport cart (10). The first guide device (28, 28?, 28?) is further set up for securing the box against displacement on the transport cart (10) in a direction perpendicular to a longitudinal axis (L) of the transport cart (10) when engaged with the complementary second guide device formed on the box. The transport cart (10) finally comprises a locking mechanism (40, 40?) which is set up for securing the box against displacement on the transport cart in a direction parallel to the longitudinal axis (L) of the transport cart (10).

Abstract: A dispenser comprises a housing that has a removable tamper proof protective cap and tamper proof ring and is threaded to a container. The container, which is the main package, holds the supplemental component. The housing holds the first component into a plunger type chamber in a fully retracted position and is sealed from the supplemental component. The chamber has a delivery end that is closed before use. When pushed all the way in, the chamber's delivery end becomes open and delivers the first component into the main package.

Abstract: A mop head assembly for use with a handle and a cleaning substrate is disclosed. The mop head assembly includes a lower substrate support surface, at least one fastener channel associated with the lower substrate support surface, and a fastener strip that can be inserted into the fastener channel. Such a fastener strip is configured to couple the lower substrate support surface to a cleaning substrate. The mop head assembly may include a cross-member configured such that forces applied from the handle through a central portion of mop head are distributed toward the end edges of the lower substrate support surface.

Abstract: A galley including a galley body on a cabin floor for accommodating storage boxes, appliances and at least one service cart; storage boxes for storing goods, and a service cart.
