    摘要： Apparatus suitable for use in positioning ceiling or wall panels in predetermined locations. The apparatus includes one or more channel means shaped to receive at least part of a panel in use, said channel means at least partially defined by one or more substantially planar outer walls and at least one inner wall. At least part of the inner wall depends away from the outer wall thereby forming the opening into said channel means through which the ceiling or wall panel is inserted in use.

    摘要： A propulsion blade retraction and pitch control apparatus includes a hollow primary drive shaft, a pitch control gear assembly mounted, within a propeller hub, to the primary drive shaft, a radially spaced array of pitch control stub shafts mounted to, in co-operation with, the pitch control gear assembly, so as to be selectively rotatable about corresponding pitch control shaft longitudinal axes upon selective actuation of the pitch control gear assembly, propulsion blades pivotally mounted to the pitch control stub shafts at ends of the pitch control stub shafts radially distal from the pitch control gear assembly, one or two coaxial nested pitch control drive shafts, rotatably co-axially journalled so as to be nested within, and co-axial to, the hollow primary drive shaft, said pitch control drive shaft or shafts selectively rotatable to actuate the pitch control gear assembly.

    摘要： Folding propeller which consists of blades (1) hinged to a hub (7) in such a way that they can turn about 56 degrees from a position at rest, where they are pointing aft, to a working position towards a stop. The identical movements of the blades (1) are achieved by the use of two cog-wheel connections, where each cog-wheel consists of only one tooth. The two connections are arranged side by side but in opposite directions in order to ensure a fixed connection. The tooth faces (10) may be given the shape of an arc of a circle. The propeller blades (1) may be fixed to the hub mechanism by means of pins (2) arranged in the longitudinal axis of the blades (1). The pitch of the blades (1) may then be changed.
