Patent GB-2458489-A (GB)
Title: Chair with seating surface and lumbar support formed from a single sheet of material
Inventor: JARVIE SCOTT
IPC: A47C5/00
Filed: 2008-03-20
Abstract: A chair is cut and produced from a single sheet 12 of normally rigid material, e.g. plywood, plastics, metal. The sheet 12 is cut along a single cutting line to form two sets of interlaced strips 10,11 which are then bent by a forming method and joined such that one set of strips becomes the seating surface and the other set becomes the lumbar support. The remainder of the sheet can define armrests. The chair may be mounted on legs made from another material [as shown in Fig. 1] or legs formed from the same single sheet [see Fig. 8].

Title: Lubrication and scavenge system
Inventor: GIBBONS JOHN LESLIE
IPC: F01D25/18
Filed: 2008-04-04
Abstract: A lubrication and scavenge system for a gas turbine, capable of continued operation in nose-down or nose-up orientations, comprises a number of oil drainage passages 40 to return oil to one or more collection chambers 30 adjacent a rolling element bearing 22. A rotary impeller 38 in the chamber 30 forces the oil into a scavenge off-take passageway 36 in the chamber wall leading to a scavenge pump (16, fig 1). However, in some orientations windage effects in the chamber 30 can return the oil to the drainage passage 40 rather than permitting the impellor 38 to centrifuge it into the off-take passageway 36. As a result oil starvation may occur. To avoid this and improve scavenging, a shield 44 is located between the drainage path 40 and the off-take passageway 36 adjacent to a face of the impeller 38. The shield 44 may comprise an additional member (figures 4a and 4b), but preferably is formed integrally with a bearing race 26so as to ease assembly (figures 5 and 6).

Patent GB-2463249-A (GB)
Title: Elastomer driven ratchet mechanism
Inventor: BUFFINTON MICHAEL
IPC: B63H9/10
Filed: 2008-09-05
Abstract: An engagement end 003 inside the ratchet mechanism rotates a flexible elastomer member 001 causing an associated biasing to urge the ratchet pawl 002 towards engagement with teeth 005 inside the sheave 004. The engagement end 003 can be a fixed termination or a rotatable/slidable shaft to which the primary switch is connected, allowing the user to engage/disengage the ratchet pawl 002. In the engaged position, the ratchet pawl 002 is locked between the sheave 004, thereby preventing the sheave 004 from turning in one direction but allowing to turn in the other. Turning the engagement end in the opposite direction causes the flexible elastomer member 001 to urge the ratchet pawl 002 away from the sheave to the disengaged position. When the ratchet pawl 002 is in the disengaged position the sheave 004 may rotate freely in either direction.
