Abstract
1,033,847. Mineral-mining installations. GEWERKSCHAFT EISENHUTTE WESTFALIA. Dec. 7, 1964, No. 49672/64. Heading E1F. To prevent overloading of a conveyer along which a coal cutting machine is hauled there is provided means, piston cylinder assembly for causing throttling of the supply of pressurised liquid from a pump to the driving motor of the haulage means of the cutting machine on a rise of pressure occurring in the supply conduit by which pressurized liquid is supplied from another independently driven pump to the driving motor of the conveyor.
