Remote-control device

Claim 1

A SYSTEM FOR THE REMOTE CONTROL OF ELECTRIC RELAY CIRCUIT MEANS THROUGH CAPACITIVE COUPLING TO AN INSULATED CONDUCTOR EXTENDING AT LEAST ADJACENT TO THE POINT OF TRANSMISSION COMPRISING A PORTABLE, LOW-POWER, HIGH-FREQUENCY TRANSMITTING MEANS, A SEPARATELY ENCASED BATTERY HAVING CURRENT-LIMITING CIRCUIT MEANS, OPERATING MEANS ADAPTED TO MODULATE THE CARRIER-WAVE OF SAID TRANSMITTING MEANS IN AMPLITUDE BY A CERTAIN NUMBER OF FREQUENCIES, EACH CORRESPONDING TO A FUNCTION OF THE ELECTRIC RELAY CIRCUIT MEANS BEING REMOTELY CONTROLLED, A COUPLER FOR CAPACITIVE COUPLING WITH SAID INSULATED CONDUCTOR INCLUDING A HELMET FOR WEAR BY AN OPERATOR, SAID HELMET HAVING AT LEAST ONE METALLIZED SURFACE INSULATED FROM SAID OPERATOR WHEN WORN THEREBY BY AN INSULATED CAP, A METALLIC ELEMENT ADAPTED TO CONTACT SAID OPERATOR''S FOREHEAD AND THEREBY PROVIDE AN EARTH RETURN THROUGH SAID OPERATOR''S BODY, A HELMET LAMP HEAD PROVIDED WITH A SUSPENSION HOOK AND A RETURN CONTACT STUD, SAID HOOK BEING CONNECTED TO SAID METALLIZED SURFACE OF SAID HELMET AND SAID CONTACT STUD BEING CONNECTED TO SAID METALLIC ELEMENT ADAPTED TO CONTACT SAID OPERATOR''S FOREHEAD, AND ELECTRIC CONNECTING MEANS TO CONNECT SAID BATTERY TO EACH OF SAID OPERATING MEANS, SAID TRANSMITTING MEANS, AND SAID COUPLER INCLUDING A FIRST CABLE CONNECTED BETWEEN SAID BATTERY AND SAID HELMET LAMP HEAD, AND A SECOND CABLE PROVIDED WITH A PLUG-IN COUPLING TO SAID TRANSMITTING MEANS, CONNECTED BETWEEN SAID BATTERY AND SAID TRANSMITTING MEANS.

Claim 2

A SYSTEM FOR THE REMOTE CONTROL OF ELECTRIC RELAY CIRCUIT MEANS THROUGH CAPACITIVE COUPLING TO AN INSULATED CONDUCTOR EXTENDING AT LEAST ADJACENT TO THE POINT OF TRANSMISSION COMPRISING A PORTABLE, LOW-POWER, HIGH-FREQUENCY TRANSMITTING MEANS, A SEPARATELY ENCASED BATTERY HAVING CURRENT-LIMITING CIRCUIT MEANS, OPERATING MEANS ADAPTED TO MODULATE THE CARRIER-WAVE OF SAID TRANSMITTING MEANS IN AMPLITUDE BY A CERTAIN NUMBER OF FREQUENCIES, EACH CORRESPONDING TO A FUNCTION OF THE ELECTRIC RELAY CIRCUIT MEANS BEING REMOTELY CONTROLLED, A COUPLER FOR CAPACITIVE COUPLING WITH SAID INSULATED CONDUCTOR INCLUDING A HELMET FOR WEAR BY AN OPERATOR, SAID HELMET HAVING AT LEAST ONE METALLIZED SURFACE INSULATED FROM SAID OPERATOR WHEN WORN THEREBY BY AN INSULATED CAP, A METALLIC ELEMENT ADAPTED TO CONTACT SAID OPERATOR''S FOREHEAD AND THEREBY PROVIDE AN EARTH RETURN THROUGH SAID OPERATOR''S BODY, A HELMET LAMP HEAD PROVIDED WITH A SUSPENSION HOOK AND A RETURN CONTACT STUD, SAID HOOK BEING CONNECTED TO SAID METALLIZED SURFACE OF SAID HELMET AND SAID CONTACT STUD BEING CONNECTED TO SAID METALLIC ELEMENT ADAPTED TO CONTACT SAID OPERATOR''S FOREHEAD, AND ELECTRIC CONNECTING MEANS TO CONNECT SAID BATTERY TO EACH OF SAID OPERATING MEANS, SAID TRANSMITTING MEANS, AND SAID COUPLER INCLUDING A FIRST CABLE CONNECTED BETWEEN SAID BATTERY AND SAID HELMET LAMP HEAD, AND A SECOND CABLE PROVIDED WITH A PLUG-IN COUPLING TO SAID TRANSMITTING MEANS, CONNECTED BETWEEN SAID BATTERY AND SAID TRANSMITTING MEANS.
