摘要:
A remotely controlled locator material dispensing apparatus for use within a conduit having an axis to mark specific conduit locations for later identification. The apparatus includes a control device located outside of the conduit for generating a plurality of control signals for controlling the operation of the locator material dispensing apparatus. The dispensing apparatus includes a first structural unit having a source of locator material to be dispensed onto an interior surface of the conduit. The first structural unit is connected to the control device for receiving the control signals therefrom, and for dispensing the locator material from the first structural unit onto the interior surface of the conduit in accordance with the received control signals. A monitor is positioned within the conduit for locating the specific conduit locations and monitoring the dispensing of the locator material.
