Abstract
1,141,191. Mining machines. COAL INDUSTRY (PATENTS) Ltd. 28 June, 1966 [30 March, 1965], No. 132489/65. Heading E1F. An arrangement for producing a signal indicative of the orientation of a mining machine in a mineral seam involves an electrical signal-producing strain gauge by which is measured the load on a cutter tool operating for at least part of its travel in the seam adjacent an interface between the seam and an adjacent stratum. Preferably the gauge reads the load the tool exerts on the holder by which the tool is supported in the cutting means of the machine.
