Abstract
A plurality of transparent members are provided each of which has an elongated flat portion with a tip portion at one end forming an obtuse angle relative to the elongated flat portion with the tip portion having a narrowed end, and a spot of material located on the tip portion that fluoresces in the presence of blacklight. The spots of the plurality of transparent members are of different sizes respectively. Also provided is a flat transparent member having a series of spaced apart lines of different lengths with dimension numbers formed next to the lines respectively. The lines and numbers fluoresce in the presence of blacklight. The plurality of transparent members and the flat transparent member are coupled together for movement relative to each other.
Claims14
A penetrant comparator, comprising:
- a transparent member comprising an elongated portion and a tip portion forming an obtuse angle relative to said elongated portion,
- said tip portion having a narrowed end, and
- a spot of material on said tip portion that fluoresces in the presence of blacklight.
A penetrant comparator, comprising:
- a first transparent member comprising an elongated portion and a tip portion forming an obtuse angle relative to said elongated portion,
- said tip portion having a narrowed end,
- a spot of material on said tip portion that fluoresces in the presence of blacklight,
- a second transparent member having a series of spaced apart lines of different lengths with dimension numbers formed next to said lines respectively,
- said lines and dimension numbers being formed of a material that fluoresces in the presence of blacklight.
A penetrant comparator, comprising:
- a plurality of transparent members each of which comprises an elongated flat portion with a tip portion at one end forming an obtuse angle relative to said elongated flat portion with said tip portion having a narrowed end, and a spot of material located on each of said tip portions that fluoresces in the presence of blacklight,
- said spots of said plurality of transparent members being of different sizes respectively,
- each of said transparent members having a connecting end opposite its said one end, and
- means for coupling said connecting ends of said plurality of transparent members together to allow said transparent members to move relative to each other.
