摘要： In order to sort ore from associated mineral material, a method and apparatus of classifying an object is provided, the method including feeding the object along a feed path, irradiating the object with infra-red radiation of a first wavelength, the radiation of the first wavelength being focussed onto an irradiation zone intersecting the feed path, the irradiation zone having a length in the vertical plane substantially greater than its width in the vertical plane. The intensity of radiation emitted by the object at at least one second wavelength different from the first wavelength is examined, the second wavelength being characteristic of a first class of object or the ore to be sorted from the mineral, whereby the classification of the object may be derived.

摘要： A method of acquiring a communications signal is provided. The method includes the steps of storing a forward chirp sync segment (106) of an auto-correlating forward chirp sync (102) and storing a reverse chirp sync segment (108) of a symmetric auto-correlating reverse chirp sync (104). A header comprising of either a forward chirp sync FCS (102) or a reverse chirp sync RCS (104), a predetermined number of data blocks comprising a data frame (308), and the symmetric auto-correlating trailer is received. The header, the data blocks, and the symmetric trailer are susceptible to frequency error. The method correlates the FCS segment (106) with the auto-correlating FCS (102) to provide a FCS correlation signal (312) and correlates the RCS segment (104) with the auto-correlating RCS (108) to provide a RCS correlation signal (314). The method determines the frequency error, symbol timing, and frame timing based upon the FCS correlation signal (312) and the RCS correlation signal (314).

摘要： In order to sort diamond-bearing ore particles conveyed on a wide belt, exciting radiation strikes the belt along an extended line. Diamonds are detected by passing the emitted radiation through a narrow band pass filter and sensing the Raman radiation with a photo-multiplier tube. Only axial-parallel rays passing through the filter reach the photo-multiplier tube. An array of side-by-side converging lenses can be used, the lenses being of rectangular shape as seen looking along the optical axis with their long axes at right angles to the line of radiation. The ore particles are in the plane of the foci of the lenses, so that radiation emitted by each particle is passed in parallel rays through the filter. In order to stop rays having an angle of incidence greater than the maximum permitted, to avoid identifying non-diamond material as diamond, a further converging lens is used to focus the rays at the plane of a telecentric stop. The stop stops rays having too great an angle of incidence. The position of the diamond can be detected for instance by a CCD array or by a time domain technique. The apparatus can be monitored by giving a signal when the radiation from tracer stones and holes on either side of the belt, differs from predetermined values.

摘要： Objects are dropped in succession through a viewing zone, where they are viewed in bright field illumination by three viewers along mutually orthogonal axes, using radiation of different wave-lengths (or viewing in rapid succession). The viewers sense the presented area. The presented areas are compared in a microprocessor in order to obtain a rough determination of the shape of the object. The presented areas can, for example, be summated to obtain a rough determination of the size of the object.

摘要： In order to provide secure and simple detection of diamonds when prospecting, a rock sample is reduced to powder particles which are automatically checked to see if they contain diamond particles (30) by processing an image of X-radiation transmitted through a layer of the particles. The image may be processed by comparing it with a further image of visible light transmitted by the layer of particles.

摘要： In order to determine the external profile of a diamond, particularly a large diamond which has re-entrant features, an elongate and thin beam is projected onto the diamond while the diamond is rotated about an axis normal to the beam; an imaging system is used to image from one side the line along which the beam strikes the diamond, this image being formed on a diffraction grating which is tilted in accordance with the Scheimpflug condition and in order to employ the first order beam of the diffraction grating. The image on the diffraction grating is viewed with a second imaging system. Furthermore, there may be a substantial improvement in light capture. The arrangement is applicable to systems other than those for determining profile.

摘要： In order to examine an object with radiation and measure the intensity of radiation used to illuminate the object, radiation is directed onto a wavelength selective mirror (31). In a first position, the mirror (31) reflects the illuminating radiation to a beam splitter (30) which passes the radiation to a detector (34). In a second position the mirror (31) directs the radiation to an object (33), radiation of the selected wavelength emanating from the object being reflected by the mirror via beam splitter (30) to the detector (34). The mirror (31) is rotated between the first and second position. In order to classify a diamond as natural or synthetic, a first signal is derived dependent upon the intensity of ultra-violet radiation transmitted by the diamond at 254 nm, and a second signal is derived dependent upon the intensity of radiation transmitted by the diamond at 365 nm and the diamond is classified as being definitely natural if the first signal is substantially greater than the second signal.
