Abstract

Rectifier transformer of alternating current to continuous with the existing grid of 220 and 125 volts indistinctly and output to 9 and 1''50 volts. Represented in the drawing by figure a. Two electrolytic capacitors figure d and e. And two rectifier bridges figures b and c. All this constitutes the power supply, b) photo-sensitive electronic circuit composed of a photoelectric cell, figure n, whose mission is to start the mechanism when detecting a shadow. Set of transistors, figure j, whose mission is to start a 6-volt relex, figure p. A capacitor figure k, and a regulator for the sensitivity of the cell, figure l. A relex of volt and a half figure g. A figure u condenser and an electromagnet, figure i. The mission of this electronic circuit is to start a toy disk-player, for which the relex of figure f gives way to the electric current that reaches the electromagnet of figure i that gives the impulse necessary for its operation. Entering into play the relex figure g to cut the passage to the electric current that may originate as a result of a new detection of a new shadow by the card. The capacitor figure h acts on the electromagnet in order to delay the impulse time. C) dc motor turntable, figure o and plastic disk that is the one that launches the advertising message. D) bulb, figure m that intermittently illuminates a luminous panel with engraved text that exposes the brand or message of a product. (Machine-translation by Google Translate, not legally binding)
