Apparatus and corresponding methods for measuring a plurality of parameters of a cut gemstone while it is positioned at a single measurement location. Apparatus comprise a plurality of light sources, each configured to emit light at a different one of a plurality of emission wavelengths or ranges of wavelengths such that the emitted light illuminates at least part of the measurement location. Apparatus further comprise a sensor assembly configured to sense light at a plurality of sensing wavelengths or ranges of wavelengths for measuring the plurality of parameters. The sensed light is received at the sensor assembly from the measurement location as a result of illumination of a cut gemstone located at the measurement location.

Measuring parameters of a cut gemstone

A method and apparatus for orientating discrete objects, such as gemstones, is described. The method comprises providing the objects on a travelling path; providing a pair of opposed walls () extending generally along the direction of the path; and generating relative oscillatory movement () between the pair of walls () and the travelling path (in a direction generally transverse to the direction of the path), so that the pair of walls () imparts lateral force to the objects to thereby urge them into their most stable orientation as they progress along the path. A device for checking the orientation of the discrete objects is also described.

A spacer for connecting an inhaler device to a mask, including an elongated cylindrical first member extending along a central axis between a proximal end adapted to receive an inhaler device and a distal end having a particle reflecting surface, and wherein the first member has an inner channel extending along the central axis, and an elongated cylindrical second member extending along a central axis between a closed proximal end and a distal end adapted to connect to a mask, wherein the second member defines an inner channel extending along the central axis of the second member and wherein the first member and the second member are connected such that the inner channels of the members are joined lengthwise.
