Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
60 words
Light flashing apparatus comprising compression means, a crystal associated with means for compression thereby, electric circuit means connected across said crystal for receiving voltage therefrom upon compression of the crystal, lamp means connected in said circuit means, and a spark gap in said circuit for concentrating a surge of current flowing through said circuit upon spark discharge across the gap.
Claim 2
Dependent Claim
60 words
Light flashing apparatus comprising compression means, a crystal associated with means for compression thereby, electric circuit means connected across said crystal for receiving voltage therefrom upon compression of the crystal, lamp means connected in said circuit means, and a spark gap in said circuit for concentrating a surge of current flowing through said circuit upon spark discharge across the gap.
Claim 3
Dependent Claim
36 words
Light flashing apparatus according to claim 1, in combination with a toy figure enveloping said compression means, crystal and circuit means, whereby manipulation of said figure operates said compression means to pass current through said circuit.
Claim 4
Dependent Claim
22 words
Light flashing apparatus according to claim 2, said lamp means simulating the eyes of said toy figure to flash upon current flow.
Claim 5
Dependent Claim
70 words
Lamp flashing apparatus according to claim 1, said compression means comprising a press including a conductive frame electrically connected to one side of said crystal, and said crystal being located in said press for compression thereby, said circuit means including an insulated conductor mechanically connected to said frame and electrically insulated therefrom, said conductor having an uninsulated portion adjacent to and spaced from said frame to define said spark gap.
Claim 6
Dependent Claim
15 words
Light flashing apparatus according to claim 4, said lamp means comprising a gas discharge lamp.
Claim 7
Dependent Claim
49 words
Apparatus according to claim 4, in combination with a toy figure enveloping said compression means, crystal and circuit, and said lamp means simulating the eyes of said toy figure, whereby manipulation of said figure operates said compression means to pass current through said circuit and flash the simulated eyes.
