Abstract: An optical sorter for grading oblong articles which are conveyed one at a time mutually spaced and usually placed perpendicular to the direction of conveyance on a conveyor belt. The optical sorter uses laser light and infra-red light sensors and an elctronic camera connected to data-processing equipment arranged to determine whether an article is to be accepted or rejected, and with at least one grading device (70) which is connected to an output from the data-processing equipment (50), and arranged to remove articles under the control of the data-processing equipment. In the new optical sorter the articles are conducted through a "blanket" of light, preferably laser light, to determine the height or "sweep" of each article, and the thickness of the article is measured by optical displacement sensors on the basis of distance measurements. In addition the measurements with the optical displacement sensors (44-47) are used to calculate the so-called "propeller" distortion of the articles by calculating a plane through the three measuring-points and calculating the distance from a fourth measuring-point to the said plane. The objects are photographed by an electronic camera (52) and the data thus recorded are used to clculate the article's length, length variations, width, width variations, rounding, so-called "banana" distortion, absolute colour and colour differences. The electronic measuring circuit is arranged to provide statistics on the deviations of the sticks (30) from the given limit values for a normal grading and if required for a second grading, and is arranged to display the results on the monitor screen (50).

Abstract: A device for inspecting and/or differentiating falling objects (11, 12), preferably free-falling tablets (13), has an illuminating device designed to produce a first distribution of light intensity in a first measuring plane, influencing the given object (12, 13) as it traverses the first measuring plane, and to produce a second distribution of light intensity in a second measuring plane that is different from the first measuring plane, influencing the given object (12, 13) as it traverses the second measuring plane. A detection device is combined with the illuminating device to form a measuring station (18), the detection device being designed to measure in two successive measuring steps the influences of the first and second intensity distributions along first and, differing therefrom, second measuring coordinates in such a way that it detects the respective dimensions of the object (12, 13) in the direction of the respective measuring coordinate. Provided also is an analysis device (19) which derives from the detected dimensions at least one control signal (S1, S2), which comprises a qualification of the particular object (12, 13), such that a downstream sorting station (21) dispatches the objects (12, 13) differently depending on the control signal (S1, S2).

Abstract: A process for separating one type of particle (e.g., ore particles) from a second type of particle (e.g., gangue particles) comprises the steps of (1) conditioning the particles with an agent comprising a compound having both a surface-selective functional group and a detectable moiety, to selectively coat one type of particle (i.e. either the ore particles or the gangue particles), to the substantial exclusion of the other; (2) detecting the coated particles; and (3) separating the detected coated particles from the substantially uncoated particles. In one embodiment, the detectable moety is fluorescent and detecting is performed under ultraviolet radiation. The process is especially useful for separating higher grade limestone from lower grade limestone and/or gangue or for separating oil shale or coal of high BTU value from lower BTU materials or for concentrating valuable minerals, such as silver or copper ores.

Abstract: In order to provide an accurate sort into many different classes, objects are passed through a viewing zone and viewed at the same instant by a number of viewers. Signals from the viewers are processed to provide signals representative of the maximum, minimum and mean of the blockiness and symmetry of the object, and the maximum and mean of the convex hull deviance of the object. The signals, together with an edge-breakthrough count are subjected to a linear transformation to provide a normalised shape parameter which is then assigned a value of 0 to 15, for each class being sorted, on the basis of the expected occurrence of the value of the parameter in that class. Each pair of secondary shape parameters so determined is used to derive a decision value from the table specific for that pair of secondary shape parameters. The shape class of the object is ascertained on the basis of a majority vote for all the shape decision values. The tables are 'learnt' by the machine by feeding a statistically significant number of samples representative of a number of shape classes through the machine.

Abstract: Method of sorting cutlery, comprising opto-electronic dynamic recognition and identification of the cutlery. The pieces of cutlery are brought forward in a longitudinal direction one by one behind each other on a moving conveyor belt (12). The movement of the belt is precision linked to a pulsator (13), which emits pulses with a frequency that is directly proportional to the speed of the belt. The pieces of cutlery are brought by means of the conveyor belt to pass one by one through an optical read-of unit (14) between a light source (32) and a bar (40) of light-recognising means (33) or light-guiding means (38) which transmit light to light-recognising means. The bar extends at right angles to the direction of movement of the belt, so that it is partially shaded by the cutlery when its passes, whereupon the light-recognising means in the parts of the bar shaded at any moment are inactivated. At a moment of time which is controlled by the pulsator the standstill of activation is recognised for all light-recognising means in the bar. The standstill of activation for at least certain selected moments of time, representing a corresponding number of optical sections of the cutlery, is communicated to a computer (6) in the form of binary words, which each represent the width of the cutlery in the present section and which together with any further data form a digital signalisation of the cutlery. This signalisation is scanned with regard to a number of digital signalisations of the different pieces of cutlery that are to be sorted which have been previously programmed in the computer's memory unit. With accord between the scanned one and any of the programmed cutlery signalisations the cutlery is guided to a box (24A-D) corresponding to this type of cutlery or correspondingly. The invention also concerns the apparatus for the execution of the method.

Abstract: Optical fibres control the height and curvature on the perpendicular level of a number of articles on a conveyor (15) while the articles traverse a box (16) in which said optical fibres are placed so that the light ray is disturbed in response to the height and curvature of the articles and outside the box (16), the articles are scanned by a camera (11). Both from the box (16) and from the camera (11) measuring data are transferred to a computer (13) evaluating the measurements and deciding whether or not the article is to be discarded when it reaches the grading device (41, 42). In this way a reliable, three-dimensional control of the articles is achieved.

Abstract: A method for the separation of calcium-containing limestone ore containing particles of calcite (CaCO3), dolomite (CaMg(CO3)2), and gangue, including magnesite (MgCO3) and siliceous materials. The method comprises conditioning the limestone ore with at least one coupling agent selected from saturated and unsaturated carboxylic acids containing from about4 to about 22 carbon atoms, or at least one coupling agent selected from the group consisting of aliphatic amines containing from about 8 to about 22 carbon atoms, and beta amines containing from about 7 to about 21 carbon atoms, to selectively coat the calcium-containing limestone or the gangue in the ore to the substantial exclusion of the other in combination with providing at least one fluorescent dye to said coupling agent; radiating the conditioned ore to excite and induce fluorescence of the fluorescent dye to a degree sufficient to distinguish the coated particles from the non-coated particles and separating the fluorescing, coated particles from the non-fluorescing, non-coated particles.
