Abstract

1349248 Measuring impact force electrically VICTOR PRODUCTS (WALLSEND) Ltd 7 July 1971 [17 July 1970] 34847/70 Heading G1N Apparatus for measuring repetitive impact comprises an anvil 1 on which the blows are made, the head 3 forming a capacitor with a plate 5 this capacitor being charged through an circuit 12, 13 giving an output A comprising a decaying wave train whose first swing is indicative of the size of the impact a demodulating circuit 15 of diode and a second larger capacitor giving an output B which may be fed to any of a number of measuring circuits. Firstly it may be connected to a rate-meter 17 (which may be a tachometer or counter); it may also be fed to a further diode and capacitor 18 giving a very slowly decaying output C which can be read on a meter 19 providing a value for the pick magnitude. The signal B may also be fed to an amplitude discriminating circuit 23 with a variable level E which may feed a rate meter 26, or counter 27 to determine the number of blows above any given level calibration may be made by dropping known weight from a known height. The device may be used to compare repetitive impact tools.
