摘要： A method is provided for determining a characteristic such as the temperature of a medium. This medium will typically be a fluid and preferably be a liquid. The method involves providing a layer (10, 32, 50) of a conductive or semi-conductive material, placing the layer (10, 32, 50) in thermal contact with the medium, causing a voltage pulse to be applied to the layer (10, 32, 50), determining the rate of change of a response induced by the voltage pulse, e.g. the rate of change of a current induced by the voltage pulse, comparing that rate of change with a standard and using that comparison to make the characteristic determination.

摘要： Particles (10) are conveyed in a stream in a direction transverse to the width of the stream. Windows (14) view individual width zones of the stream and optical fibres (19) are associated with the windows to convey light passing through a window to a light detector (21). The windows (14) are rapidly opened and closed and a processor (32) is provided to determine which window (14) passed light detected by the detector (21) and accordingly which width zone of the stream the light emanated from. The windows (14) preferably incorporate liquid crystal shutters (24) which can be switched rapidly between light-transmitting and opaque states corresponding to open and closed states of the windows (14).

摘要： The invention provides a method of making an abrasive product which comprises a layer of bonded ultra-hard abrasive particles bonded to a substrate. This abrasive product is typically a composite abrasive compact. The method includes the steps of:
(a) providing a slurry of the components, in particulate form, necessary to make the layer of bonded ultra-hard abrasive particles in a liquid which contains a binder dissolved or dispersed therein; (b) providing the substrate (14) which has side surfaces (18) and an end surface (16) to which the layer of bonded ultra-hard abrasive particles is to be bonded; (c) providing a container (10) which is adapted to receive the substrate (14) such that the side surfaces thereof form a close fit with the container; (d) placing a quantity of the slurry (12) in the container (10); (e) inserting the substrate (14) into the container (10) such that the slurry is pressed between the container (10) and the surface (16) of the substrate to which the layer of bonded ultra-hard abrasive particles is to be bonded; (f) removing substantially all the liquid and binder from the slurry; and (g) subjecting the contents of the container to suitable elevated temperature and pressure conditions in the reaction zone of a high temperature/high pressure apparatus.
