Abstract: According to this application there is provided a portable sharpening device. More specifically, a portable sharpening device comprising a body portion comprising a surfacing member, a mouth in communication with the surfacing member, arranged to guide an object to be sharpened towards the surfacing member; wherein the device is arranged to sharpen a face of said object by relative movement between the surfacing member and the object to be sharpened and wherein said relative movement is created manually by a user.

Abstract: A support for an electrical display device such as a monitor is disclosed. The support includes a pair of support members (2,3) connected by a pivot joint (4) to enable relative movement of the support members (2,3) about an axis of rotation, the joint (4) including an outer hub (11) mounted for rotation about the axis within a clamping member (5) attached to one support member (2), an inner hub (10) mounted to the other support member (3) coaxial with the outer hub (11) and being rotatable about the axis relative to the outer hub (11) in a first direction and, a clutch member (12) between the inner and outer hub (10,11) engageable in response to rotation of the inner hub (10) in the opposite direction such that the outer hub (11) rotates together with the inner hub (10) when a compressive force exerted on the outer hub (11) by the clamping member (5) is overcome. A universal joint (7) is also disclosed.

Abstract: Ornamentations for wheel assemblies that are rotatably mounted on the hub assemblies of the wheel assemblies and configured to produce a variety of visual and/or audible effects. The ornamentations develop a spinning motion as the wheels rotate and remain spinning for a period of time after the rotation of the wheels is stopped. The ornamentations are generally disc shaped and can include light and/or sound generating elements. The ornamentations can be used in conjunction with spoked wheels such as bicycle wheels.
