Filed: 1968-02-02
Abstract: 1,152,407. Sorting ores by reflectance. SPHERE INVESTMENTS Ltd. Feb.2, 1968, No.5527/68. Heading G1A. In a method and apparatus for sorting irregularly shaped objects such as ores in which the objects are moved through a sorting zone which is scanned repeatedly across the zone to detect light reflected from discrete areas of the objects and zone, a series of at least three parameters are derived from the reflected light, a plurality of them are selected for comparison in a predetermined manner, and the result of the comparison is used to effect acceptance or rejection of an object . The ores are fed from a hopper to a belt conveyer passing through the sorting station by way of two vibrating conveyers and a shoot, the last named accelerating the lumps to approach the speed of the test conveyer which is faster than the others, to achieve separation of the pieces. The test conveyer may be black or white to provide a desirable background for the rock being sorted and the sorting is by blasts of compressed air from one of a number of apertures corresponding to the identified position across the belt of the object. The light source, which may be a laser, and the detector are repeatedly scanned across the belt, by a mirror drum, the detector including a polarizer to receive the reflected laser light and reject specular reflection. Photo-cells determine the lateral limits of each scan and a reflecting standard is included in the scanned path for calibration purposes. A draught of air and screens may be provided to keep dust from settling on the optical apparatus. The apparatus is described for sorting gold ore and in this case the following parameters are selected by preset switches for determination. The number of white areas per unit of area. The area of a piece of rock. The black area of the piece of rock.

Abstract: 279,309. Nitschke, A., and M³nzberg, R. Feb. 28, 1927. Detonator apparatus; track apparatus for actuating signals on, and for stopping, trains.- Portable signalling apparatus for protecting workmen on the line comprises a signal-operating or train-stopping device placed at a distance from the workmen and a control device therefor located near the workmen. In one form a base a' temporarily fixed near the workmen has a pulley d<1> rotatable by handles h, h<1> (90‹ apart) to one or other of two positions in which it is held by a tethered link i with an eye adapted to engage a handle. A transmission rope k operated by the pulley passes between guide pulleys g<1>, g to a pulley d mounted on a base a temporarily fixed beside the track at a sufficient distance away from the workmen. The shaft of pulley d carries an arm e which, when in the raised or danger position, acts as an abutment to operate a contact arm on the locomotive controlling an audible signal or applying the brakes. Instead of acting as an abutment the arm e may carry an electromagnet for influencing train-carried apparatus.
