Definitions
- the invention contemplates improved flaw marking apparatus useful with detection apparatus of the type including: scanning means for scanning a generally planar body of substantially homogeneous material with a scanning beam and for providing a flaw indication output in response to each irregularity in said body encountered by said scanning beam; and position indicating means for identifying which of a predetermined plurality of areas of said body said scanning element is traversing at each instant.
- the improved marking apparatus comprises: first marking means for marking each area of said body in which such scanning beam encounters an irregularity; detectormeans for inspecting said body of material in regions thereof subjected to said first marking means, and effective to determine whether or not a detected flaw has been properly marked; second marking means including a single movable marking device; and means for moving said single marking device to mark an irregularityin response to a signal from said detector means in the event of failure effectively to mark by said first marking means.
- FIG. 3 is a circuit diagram of-control elements associated with the marking gun unit.
- a backup marking gun 17 is positioned downstream of primary marking guns 14-1, 14-2 and'is capable 'of being selectively located to substitute for any one of the eleven primary guns.
- the primary control computer unit 11 includes position indicating means, of known type, for identifying which of a predetermined plurality of areas the scanning unit is traversing at each instant, a sampling pulse terminal 22, ane eleven mark gate terminals 21-1 to 21-11, one in correspondence to each of the eleven primary marking guns 14-1 to 14-1 1.
- position indicating means of known type, for identifying which of a predetermined plurality of areas the scanning unit is traversing at each instant, a sampling pulse terminal 22, ane eleven mark gate terminals 21-1 to 21-11, one in correspondence to each of the eleven primary marking guns 14-1 to 14-1 1.
- One of eleven identical mark sampling unit computers is shown in detail at -1, and since operation of each such computer is identical to the other, description of operation of the system will be made in light of the sin-' gle computer 110-1 and those of the other duplicate elements associated therewith.
- block 110-2- is shown with its connection made to leads or terminals identified in correspondence with leads connected to block 110-1, but which terminals bear the suffix 2.
- said means for generating a signal includes, in series electrical circuit with said photodetector means: a preamplifier; a comparator; an inverter; and one terminal of a three-input NAND gate, the output terminal of the latter being connected to the input terminal of a flip-flop having a 6 and a Q output terminal; said means for generating a signal further including: a twoinput NAND gate and a connection between the 6 terminal of said flip-flop and one input terminal of said NAND gate; a NOR gate; a connection between the output terminal of said NAND gate and one input terminal of said NOR gate; a relay driver and a motor control relay connected in series electric circuit, and a connection between the output terminal of said NOR gate and said relay driver; an inverter; a connection between the output terminal of said inverter and the other input terminal of said two-input NAND gate; means for producing a signal at each of the stations traversed by said movably mounted marking device
