Abstract: A watch winder (1) comprises a fixed assembly having a central shaft 92), a rotatable assembly rotatably mounted to the central shaft and comprising a housing (3) having distal end configured to receive a watch, and a drive assembly mounted on the fixed assembly to and configured to rotate the rotatable assembly about the central shaft and comprising a motor (7), drive gear (8, 30, 32, 33), and a battery assembly (9, 10) operatively connected to the motor. The drive assembly is mounted to the fixed assembly within the housing (3) of the rotatable assembly, and the central shaft extends proximally of the housing (3). The housing is axially mounted on the central shaft (2) by means of a distal bearing plate (18) and a spaced apart proximal bearing plate (19), wherein the drive assembly is fixed to the central shaft between the two spaced apart bearings plates. The provision of two spaced-apart bearing plates reduces the forces exerted on the bearings, reducing the energy consumption of the device.

Abstract: A device for continuously feeding media from an unpressurised container to a pressurised chamber without depressurising the chamber is described. The device comprises a cylinder having two chambers defined by a top wall, and bottom wall, and a dividing wall intermediate the top and the base walls. The top wall comprises an inlet aperture for inlet of media and a pressure equalisation aperture. The dividing wall comprises an inlet aperture for receipt of media from the first chamber and a pressure equalisation aperture in fluid communication with a first pressure equalisation conduit that extends from the second aperture to a top of the first chamber. The bottom wall comprises an inlet aperture for supply of media to the blasting machine and a pressure equalisation aperture in fluid communication with a second pressure equalisation conduit that extends from the pressure equalisation aperture to a top of the second chamber.

Abstract: A watch support (1, 30) comprises an upper part (2) operatively connected to a lower part (3) for movement between a contracted orientation and an expanded orientation, and biasing means for biasing the upper and lower parts into the expanded orientation. The upper part (2) comprises a pair of adjustable wings (6, 7) that are moveable relative to the upper part between an extended position and a folded position, wherein each wing (6, 7) is operatively connected to the lower part (3) such that movement of the two parts (2, 3) into a contracted orientation effects movement of the wings (6, 7) into a folded position and movement of the two parts (2, 3) into an expanded orientation effects movement of the wings (6, 7) into an extended position.

Abstract: The invention provides a dosing device for a particulate material blasting apparatus comprising a dosing chamber having a base, a rotor carrying a plurality of circumferentially formed pockets ratably mountable with the chamber, a particulate product feed conduit adapted to feed particulate product onto a base of the dosing chamber adjacent a receiving side of the dosing chamber and a particulate product delivery conduit formed in the base of the dosing chamber adjacent a delivery side of the dosing chamber. The base of the dosing chamber is disposed with respect to the particulate product feed conduit such that particulate material will not spill over the base into the delivery conduit. The rotor is disposed with respect to the feed conduit such that particulate product fed onto the base of the dosing chamber will be picked up by the pockets formed in the rotor and lifted up and around the chamber from a receiving side of the dosing chamber to a delivery side of the dosing chamber.
