Abstract
1401941 Detecting foreign matter in transparent containers EMHART CORP 15 Jan 1973 [26 Jan 1972] 2074/73 Heading G1A In a modification of the comparison circuit of the device of Specification 1269515 for inspecting liquid filled transparent containers for foreign matter etc. wherein each container 10 is rotated then stopped leaving the liquid 20 inside to swirl around, the illuminated container is viewed by a video camera 30 and parts of the generated voltage pattern 36 (frame) greater than a threshold voltage level 46 are stored in the form of pulses 44 in a memory 40 for comparison (subtraction) with similar pulses formed from a later frame so that the pulses due to defects and blemishes on the container (which are in the same position in the frames) cancel, whereas pulses due to foreign matter swirling inside do not cancel and may be used to provide an error signal. The predetermined voltage of the comparator circuit is modified the relative sensitivity of the circuit is increased at the locations of the frame corresponding to pulses of the stored frame thereby lessening the likelihood of spurious error signals due to stationary dust particles, or glass defects as caused by voltage drift and/or light intensity variations. The relative sensitivity of the comparison circuit may be increased by decreasing the threshold voltage Figs. 4, 5, 6 and 7 (not shown) at the locations in the succeeding frames corresponding to the locations of the stored pulses and/or by increasing the threshold at all parts of the succeeding frame other than at the locations in the frame corresponding to the stored pulses Figs. 8, 9, 10, 11 (not shown). Circuits (Figs. 7 and 11) are disclosed for achieving this.
