Abstract: A vacuum cleaner includes a filtration chamber with an inner wall and an outer wall, an air inlet arranged to feed air carrying dust particles into the space between the inner wall and outer wall of the filtration chamber and a dirt chute for discharging dirt and/or dust from the vacuum cleaner. A tapered filter is located between the inner wall and the outer wall of the filtration chamber. The tapered filter includes a narrow end and a wide end, and the narrow end of the filter is located at or proximate to the air inlet and/or the dirt chute.

Abstract: A separating apparatus for a vacuum cleaner has a cyclonic separating chamber, an inner debris collection chamber for collecting debris separated by the cyclonic separating chamber, and an outer debris collection chamber for collecting debris separated by the cyclonic separating chamber. The inner debris collection chamber has a main body and a base mounted to the main body by a hinge. The hinge is formed of an elastomeric material.

Abstract: A dirt separator for a vacuum cleaner includes a first separation stage having a first dirt collection chamber; a second separation stage downstream of the first, the second separation stage having a second dirt collection chamber; a lid movable between closed and open positions to selectively block and unblock an emptying aperture provided in the first dirt collection chamber; and a latch mechanism. The first and second dirt collection chambers are movable relative to one another. The latch mechanism is configured to secure the dirt collection chambers in a first position, and to secure the lid in the closed position. The latch mechanism is configured to allow the first and second dirt collection chambers to move towards a second position, and to allow the lid to move towards the open position, when the latch mechanism is in the releasing configuration.

Abstract: An autonomous vacuum cleaner having a bump detection system, the vacuum cleaner comprising a chassis having traction means for supporting the chassis on a surface and a cleaner head defining a dirty air inlet, and a body carried on the chassis and being movable relative to it in response to a collision with an obstacle, the body including at least one of an airflow generator for generating an airflow along an airflow path from the dirty air inlet to a clean air outlet and a separating apparatus positioned in the airflow path to separate dirt from the air, wherein the vacuum cleaner further comprises sensing means for sensing relative movement between the chassis and the body.

Abstract: There is provided an aircraft seat cubicle that has a seat convertible to a bed, a foot rest or ottoman, a table and a light, each movable lengthways of the cubicle. One of the items of furniture is received on a track. The item of furniture can be driven towards or away from the seat via a pulley, a cable, and a drive motor. A tension spring in the run of the cable stretches and releases its tension in order to allow the cable to slip on a capstan at one end of the track for driven movement of the furniture.

Abstract: An aircraft seat has a chassis (21), fixed to a pallet which is fixed to the floor of the aircraft. The chassis has two load bearing sides (23) and opposite ends (24, 25). Fixed along the top edge of the sides (23) and facing outwards are pins (26) supporting bearing wheels (27). These on each side engage with a rectangular S form interconnection beam (28) having an inside groove (29) for receiving these wheels. On the outside, the beam has another groove (30) receiving similar wheels (31), on pins (32) fixed to the inside of side plates (41) of a sub-frame (42), these side plates being interconnected by front and rear beams (43, 44). Thus the sub-frame can move back and forth, with the wheels acting as rolling element bearings. The beams move half the distance of the sub-frame, in analogous manner to the bearing of filing cabinet drawers.

They run around front and back guide pulleys (34), pinch pulleys (35) and drive pulleys (36).

Abstract: A seating unit for a passenger vehicle, especially an aircraft, has a reclinable seat back connected to a seating portion by a hinge. A slider is mounted in a guide track and supports the hinge. A pivotally connected front strut supports the seating portion at a location in front of the hinge. A pivotally connected rear strut supports the seat back at a location spaced apart from the hinge. As the slider along the guide track, the seat back moves to an orientation substantially coplanar with the seating portion so as to provide a flat surface for a sleeping passenger.
