Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 116 words
A photoflash lamp array comprising a circuit board, a plurality of elongated flash lamps arranged in front of and parallel to said circuit board, a reflector unit positioned between said flash lamps and said circuit board, flash indicator material positioned behind said circuit board, aligned openings through said reflector unit and said circuit board between respective flash lamps and said flash indicator material to permit radiation from said lamps when flashed to reach said flash indicator material, wherein the improvement comprises at least one rim extending from a flash indicator opening of said reflector unit into the corresponding flash indicator opening of the circuit board so as to align the reflector unit with the circuit board.
Claim 2
Dependent Claim 116 words
A photoflash lamp array comprising a circuit board, a plurality of elongated flash lamps arranged in front of and parallel to said circuit board, a reflector unit positioned between said flash lamps and said circuit board, flash indicator material positioned behind said circuit board, aligned openings through said reflector unit and said circuit board between respective flash lamps and said flash indicator material to permit radiation from said lamps when flashed to reach said flash indicator material, wherein the improvement comprises at least one rim extending from a flash indicator opening of said reflector unit into the corresponding flash indicator opening of the circuit board so as to align the reflector unit with the circuit board.
Claim 3
Dependent Claim 41 words
An array as claimed in claim 1, in which at least two of said flash indicator openings of the reflector unit are provided with said rims extending from the reflector unit into the corresponding flash indicator openings of the circuit board.
Claim 4
Dependent Claim 60 words
An array as claimed in claim 2, in which said array is elongated and has one of said lamps and openings of the reflector unit and circuit board respectively nearest the two ends of the array, said extending rims of the reflector unit being at said openings of the reflector unit and circuit board at said ends of the array.
Claim 5
Independent Claim 130 words
A method of making a multiple flash lamp array, comprising the steps of providing a circuit board having flash indicator openings therethrough, providing a plurality of flash lamps and connecting their lead-in wires to said circuit board with the flash lamps extending substantially perpendicularly to said circuit board, providing a reflector unit and positioning same over said circuit board, said reflector unit having flash indicator openings corresponding in position with those of said circuit board, at least one of said flash indicator openings of the reflector unit being provided with a rearwardly extending rim which extends into the respective flash indicator opening of the circuit board, and thereafter bending the lamps by their lead-in wires so that the lamps are substantially parallel to the circuit board and the reflector unit.
Claim 6
Independent Claim 130 words
A method of making a multiple flash lamp array, comprising the steps of providing a circuit board having flash indicator openings therethrough, providing a plurality of flash lamps and connecting their lead-in wires to said circuit board with the flash lamps extending substantially perpendicularly to said circuit board, providing a reflector unit and positioning same over said circuit board, said reflector unit having flash indicator openings corresponding in position with those of said circuit board, at least one of said flash indicator openings of the reflector unit being provided with a rearwardly extending rim which extends into the respective flash indicator opening of the circuit board, and thereafter bending the lamps by their lead-in wires so that the lamps are substantially parallel to the circuit board and the reflector unit.
Claim 7
Dependent Claim 26 words
A method as claimed in claim 4, in which at least two of said flash indicator openings of the reflector unit are provided with said rims.
Claim 8
Dependent Claim 60 words
A method as claimed in claim 5, in which said array is elongated and has one of said lamps and openings of the reflector unit and circuit board respectively nearest the two ends of the array, said extending rims of the reflector unit being at said openings of the reflector unit and circuit board at said ends of the array.
