Abstract: A footrest for being supported upon a bulkhead of a vehicle, the footrest comprising a support member comprising a storage compartment for receiving and carrying one or more documents or portable electronic devices and a foot member, wherein the foot member is pivotably coupled to the support member such that the foot member is movable between stowed and deployed states and means for releasably retaining the foot member in the deployed state relative to the support member.

Abstract: A seating arrangement comprising at least one seat; a console adjacent the at least one seat; a deployable table assembly; and locking device. The table assembly is movable in a longitudinal direction from a stowed position into a deployed position in which it is located on an upper surface of the console. The locking device is operable to releasably engage the table assembly in the deployed position to prevent movement of the table assembly in a lateral direction.

Abstract: A foot rest installation comprising a base structure that includes a footwell and may be provided under a seat, in a bulkhead or in a console, and a foot rest assembly. The foot rest assembly has a deployable foot rest support structure and a first foot rest component comprising a flexible structure, for example a net, having a first end fixed with respect to the base structure at a first location, and a second end coupled to the foot rest support structure at a second location that is spaced apart from the pivot axis along a front-to-rear axis. When deployed, the foot rest support structure extends downward and rearward from the pivot axis to deploy the net in the footwell. When stowed, the foot rest support structure extends upward and rearward from the pivot axis.

Abstract: A waste removal and transfer assembly for a 3D printing system comprises a waste material remover and a waste material collector. The waste material remover comprises a movable waste removing element selectively movable into contact with a planerizer roller to remove 3D printing waste material from the planerizer roller. The waste material remover is coupled to translate with the planerizer roller and comprises an opening leading to a waste material receptacle configured to receive waste material and at least one port selectively operable to transfer waste material from the waste receptacle. The waste material collector has a receiving position that is stationary relative to the waste material remover. The waste material collector comprises an opening and a waste material storage recess to receive waste material transferred from the waste material remover via the at least one port and to store the received waste material for subsequent disposal.

Abstract: A deployment mechanism for a seat table has a non-linear motion slide comprising a primary carriage movable back and forth along a primary track. A secondary carriage is coupled to the primary carriage and moves with the primary carriage. A secondary non-linear track runs non-parallel with the primary track. The secondary carriage is coupled to the secondary track and is movable back and forth along the secondary track. The coupling between the secondary carriage and the primary carriage allows relative movement between the carriages in a transverse direction and allows relative rotation between the secondary carriage and the primary carriage about a perpendicular axis.

Abstract: A noise suppression system for a jet engine of an aircraft having a device for blocking a flow of exhaust gases down the exhaust nozzle of the engine, and a device for separating the exhaust gases into a plurality of exhaust streams spaced a predetermined distance apart and having a smaller cross-sectional area than that of the original flow of exhaust gases. The separating device also directs the exhaust streams into the ambient air from points outside the periphery of a nacelle covering the engine. The aforementioned predetermined distance separating the exhaust streams, and the cross-sectional area of the exhaust streams, are chosen so that engine noise is shifted to a higher frequency spectrum than that of the original flow of exhaust gases, and then substantially dissipated within a short distance of the aircraft.

Abstract: A bearing housing for a heavy rotor is made axially-nonsymmetrical so that the bearing chamber therein is shifted axially of the rotor shaft upon reversing the bearing housing. With a new rotor, the nonsymmetry positions the bearing chamber axially outwardly from the housing center. When necessary, the rotor shaft, by virtue of having successively increased diameters inwardly from its end, can be reworked by turning new surfaces thereon positioned axially inwardly from the original surfaces. The bearing housing is then reversed so that its nonsymmetry locates the bearing chamber inwardly from the housing center, to accommodate the new positions of the shaft surfaces.
