Lighting system for rotatable toy
First Claim
1. In a toy of the type having a body rotatable about a central axis and at least one lamp, a battery and associated circuit to light said lamp, the improved lighting system which comprises a solid state astable multivibrator circuit adapted to generate pulses to light said lamp for a predetermined on-time at predetermined intervals said circuit including a first resistor, a second resistor and a capacitor arranged in series so that said second resistor and capacitor determine said on-time of said lamp and said first resistor, said second resistor and said capacitor in series determine said interval;
- a resistive switch interposed in said circuit in parallel with said first resistor, said resistive switch including a third resistor and a normally open switch arranged so that when said normally open switch is closed said first resistor and said third resistor are in parallel to each other and are each in series with said second resistor and said capacitor, and said normally open switch includes means to close said switch in response to rotation of said toy about its central axis faster than a predetermined rate.

Abstract
There is disclosed an illuminated flying saucer toy is which incandescent lamps are pulsed on and off by an astable multivibrator circuit. The circuit is arranged to pulse at a relatively slow rate when the toy is at rest and at a relatively increased rate when the toy spins at a rate above a predetermined minimum. The increased flash rate is provided through a normally open switch that closes upon rotation of the toy to insert additional resistance into the circuit in parallel with existing resistance thereby to reduce the resistance by which flash interval is determined.
