Abstract: A scraper assembly is pivotally supported for biased engagement with the outer surface of a moving conveyor belt to clean the surface of the belt. The scraper assembly includes a plurality of scraper elements spaced along the length of an elongate carrier which extends transversely of the side edges of the belt. Each scraper element is removably mounted on the carrier and at an inclined angle with respect to the direction of movement of the conveyor belt to displace material clinging to the surface of the belt outwardly towards the edges of the conveyor belt. The scraper element consists of a resilient body with a fixedly vulcanized assembly profile with an outwardly open undercut groove for a bolt. The undercut groove extends at an inclined angle towards the scraping edges of the scraper element. The elongate carriers of the carrier device have a curved carrying surface facing the scraper elements. The opening edges of the undercut groove abut against this carrying surface for orientation of the groove parallel with the carriers and thereby for orientation of the scraper elements obliquely with respect to the direction of travel of the conveyor belt.

Abstract: CANADIAN PATENT APPLICATION OF BERTIL BRANDT FOR MILL LINING A mill lining is disclosed, intended for e.g. a primary or autogenous  mill in the mining industry. The lining comprises shell plates and lifter bars made from elastomer material and mounted in a mill drum. The lifter bars extend substantially in the axial direction of the mill drum and project into the mill drum beyond the inner surface of the shell plates. At least some of the lifter bars, preferably every second, are designed to act as elastomer springs by having a longitudinal recess or slot in their impact front side facing forwardly in the contemplated direction of rotation of the mill drum. The recess or slot is inside the inner surface of the shell plates and serves as a strain concentrator concentrating the tensile strain of the lifter bars to an area relatively unexposed to sliding abrasion of the material being ground.

Abstract: This invention relates to a burning furnace of hot gas recirculation type for minimizing fuel cost. The furnace includes a cyclone which receives dust-containing exhaust gases. One or more secondary air-introducing nozzles are provided for the cyclone at top of or in close proximity to the upper end of the cyclone leading concentrically to a flue gas passage such as funnel. Upon introducing secondary air under pressure into the cyclone, a downwardly directing swirling air flow is formed therein for the separation of heavier dust together with part of the fed exhaust gases. The thus separated air-hot gas mixture including heavier dust particles is returned to initial stage of the furnace for the recirculation through the furnace. Lighter combustible soot or the like particles are burnt in a flame curtain formed in the cyclone and finally discharged together with main and substantially dust-free exhaust gas portion constituting an upwardly directing swirling core flow in the downwardly directing and swirling outer air flow, into the flue gas passage.

Abstract: The invention is a device for, in portions, discharging a substance that has been supplied to the discharge device (10) by means of a standard feed system. Both the discharge device and the feed system are connected to a pressurized medium source and a control (13) is designed to allow the pressurized medium to pass in to the discharge device in pulses to make it operational.The innovation is that the discharge device (10) comprises a first cylinder/piston device (20, 21) with a large area that can be displaced by means of the pressurized medium with which is connected a second cylinder/piston device connected to a piston with a substantially smaller area and is displaceable together with the first piston. At the cylinder/piston device (15', 29) with a smaller area there is a feed (31) for the substance under pressure that has a non-return valve and discharges into the cylinder space (15') and an outlet that has a non-return valve and leads to a space inside of a holed discharge nozzle (18). Displacement of the first piston (21) caused by the pressurized medium is designed in such a way that when the substance is discharged through the nozzle past the second non-return valve device (35), it results in displacement of the second piston (29) and the second non-return valve device (35), which is situated at the outlet, is equipped with a valve body (35) that is fit into a seat (16) that is designed in such a way that when the valve body (35) is reset in the space beyond the valve device, there is a backflow effect that hinders remaining drops.<IMAGE>

Abstract: Interferometers are known for measuring the displacement of an object 6 with an accuracy of a fraction of 1  mu m, having digital display, and forward/reverse motion discrimination. To avoid the use of a special frequency stabilised laser source producing oppositely polarised beams of different frequencies, an interferometer is provided having a simple laser source 1, in which an interference line pattern is formed on a detection system 20 having a moving grating-like structure whose grating period corresponds to the period of the interference pattern. The effect of a moving grating is provided by a detection system comprising a linear array of photodiodes in which sequential activation of interjacent groups of photodiodes by a ring counter moves an effective grating pattern along the array. By counting the number of periods in the output signal of the detection system, changes in the measuring arm b of the interferometer can be measured with high accuracy. The interferometer may assist in measuring and controlling the movement of an optical recording head (Figure 7). <IMAGE>
