Abstract: An articulating frame comprising parallel aligned base frame elements (2A, 2B) in a first plane adjustably connected to parallel aligned upper frame elements (4A, 4B) in a second plane, parallel to the first plane, the adjustable connection between any pair of connected base frame (2A, 2B) and upper frame (4A, 4B) elements comprising one or more knuckles (10A, 10B, 10C, 10D) each knuckle being capable of a combination of rotational and linear movement and operable independently of the others to provide both linear and rotational repositioning of a frame element (2A, 2B; 4A, 4B) relative to the other of the connected pair at the point of connection.

Abstract: A fluid actuated energy generator comprises; an output shaft (44) rotatably mounted in a housing (54), a first linkage (36) arranged to rotate with the output shaft (44) and extending in an axis orthogonal to the axis of the output shaft (44), a second linkage (22) rotatably mounted in relation to the first linkage at the radially most distal end thereof, the first and second linkages (36, 22) arranged for rotation in parallel planes, an actuating arm (4) rotatably mounted in relation to the second linkage (22) at the radially most distal end thereof and arranged for rotation in a parallel plane with the first and second linkages (36,22) and at least one blade (2) rotatably mounted in relation to the arm (4) at the radially most distal end thereof and arranged for rotation in a parallel plane with the arm (4), first and second linkages (36, 22), the longitudinal axis of the blade (2) extending orthogonally to the longitudinal axis of the arm (4).

Abstract: A manoeuvrable platform comprising a planar base manoeuvrable by at least one cam operated lifting sub system positioned in relation to a back surface of the base, the or each lifting sub system comprising a cam blade arranged in a plane substantially parallel to that of the planar base section and operably connected to a cam drive in a casing, a first linear actuator operably connected to the cam drive casing and configured to provide linear displacement along a first axis, a second linear actuator operably connected to the cam drive casing and configured to provide linear displacement along a second axis and a pivoting means arranged for rotating the planar base.

Abstract: A support section for a seat (2) comprises a load responsive framework wholly or partially enclosed in amorphous upholstery, the frame work comprising multiple independently operable load responsive sub systems which collectively permit the support section to respond and react to local areas of loading whereby to provide superior support and comfort to the seat occupant. The support section may be embodied as the whole or a part of; a seat back rest and/or a seat base.

Abstract: A gearbox having a housing, an actuator, a leadscrew rotated by the actuator, a rack nut threadingly engaged with the leadscrew to move longitudinally as the leadscrew rotates, a toothed section that moved with the rack nut, a shaft and a gear integral with or coupled to the shaft, and arranged such that rotation of the gear causes rotation of the shaft.

Abstract: A system having a rotary output, including a drive shaft, a pin coupled to the drive shaft and an output shaft coupled to the drive shaft. A guideway is associated with the output shaft. Rotation of the drive shaft results in rotation of the output shaft and the guideway and movement of the pin along a pin path. The system is prevented from providing a rotary output when the pin abuts against a sidewall of the guideway, but permitted to provide a rotary output when the portion of the guideway aligned with the pin path corresponds with the position of the pin.

Abstract: A linkage includes two gearboxes each having a driven shaft, and at least one linear actuator connected between the gearboxes. Actuation of the at least one linear actuator adjusts the relative position of the driven shafts for the two gearboxes with respect to each other.

Abstract: A raiser seat for assisting a person from a sitting to a standing position is described. The seat comprises: a seat frame (4); a seat (10) supported for movement relative to the seat frame between a lowered position and a raised position; and a movement mechanism for moving the seat between the lowered and the raised positions. The movement mechanism comprises at least one cam (104) and the seat rests on the at least one cam such that rotation of the at least one cam results in movement of the seat relative to the seat frame.

Abstract: The present invention discloses an arrangement for cooling a roll (5). The arrangement comprises a housing (2) to be secured to the roll (5), a hollow shaft (8) mounted for rotational movement within the housing (2) and a cooling medium line to convey cooling medium into the roll (5) via the interior of the shaft (8). The cooling medium line comprising an inlet communicating with an elbow portion, a first length (27) of the elbow portion (20) extending from the inlet substantially perpendicular to the axis of the shaft and a second length (26) of the elbow portion extending from the first length in the direction of the axis of the shaft (8), the axes of the first and second lengths being in substantially the same plane.
