Title: Scintillation camera for high activity sources
IPC: G01T1/164
Filed: 1975-11-26
Abstract: 1536126 Scintillation camera G D SEARLE & CO 26 Nov 1975 [27 Nov 1974] 48554/75 Heading H4F An Anger-type scintillation camera signal processing system for computing the position of detected events is provided with buffer storage stages between successive computing stages in order to accommodate temporary statistical increases in the rate at which signal pulses are received for processing. The system can further be provided with means for setting an energy "window", signals lying outside the window being rejected, and this can be done before the signal pulse is fully developed by predicting its probable value. Means can additionally be provided for detecting and rejecting spurious signals arising from a second pulse developing "on the tail of" a preceding pulse and thus showing a false energy level.

Title: Web inspection apparatus
IPC: G01N21/89
Filed: 1971-10-19
Abstract: 1371912 Web defect inspecting apparatus EASTMAN KODAK CO 19 Oct 1971 [19 Oct 1970] 48562/71 Heading G1A In a web defect inspecting apparatus, Fig.1, employing a flying spot scanner 10 the reflected light from the web 12 and its support surface 14 is received by a photo-detector 18 whose signal is passed via an amplifier 20 to an AND gate 22 which also receives signals from an edge blanking circuit 26 which operates such that the gate circuit 22 only passes signals to a defect registering circuit 24 when the radiation beam is sweeping across the web 12. Fig.7, shows the edge blanking circuit in detail. A monostable multi-vibrator, responsive to the output of a photo-detector 28, which detects the beginning of each scan, produces a pair of complementary clock pulses 34 and 36 each having a duration ST/2 (where ST equals the scan duration). A differentiator 32 receives the output of the photo-detector 18 and produces a pair of "spike" signals representing when:-(i) the radiation beam travels on to the web support surface C; (ii) off the support surface on to the web D; (iii) off the web back on to the support A; and (iv) off the web support surface B. Only the spike signals D and A corresponding to the edges of the web are required and these are selected by means of polarity detectors 33 and 35 (Schmitt triggers respectively responsive to predetermined negative and positive signal level outputs) whose respective outputs are applied to AND gates 40 and 42 together with respective clock pulses 34 and 36. In order to cut any signal from the areas of the web adjacent each edge where there may be some splitting or ragged edges &c., on an otherwise perfect section of the web, the signals A and D are delayed to be effective in the next scan and to occur at times (Z, X) Fig.2 (not shown) when the scanning beam is inside the web to the extent of being unaffected by any edge faults. To delay the signal D as required, a pair of multi-vibrators 48 1  and 48 2  are employed their nett effect being a delay of ST + #T. Similarly the signal A is delayed by a pair of multi-vibrators 50 1  and 50 2  whose nett effect is a delay of ST - #T. Thus by means of the delay devices 48 and 50 a bi-stable multi-vibrator 44 is reset and set to produce blanking signals in response to a given pair of D and A signals, a little more and a little less than a scan duration after the D and A signals are produced. If the web contains a large defect the resulting signal (S 1 ), Fig.8 (not shown) may be large enough to trigger the Schmitt trigger 33, before its normal time and thereby cause an effective widening of the next blanking pulse from the multi-vibrator 44. This effect is nullified by means of an AND gate 60, a monostable multivibrator 62 and a bi-stable blank inhibitor 64 which together are effective to sense a large defect signal and hold the bi-stable multi-vibrator 44 in its reset state and prevent the next blanking pulse so that the gate 22 remains in its signal passing state.
