Abstract: An enhanced daytime and nighttime visibility marker for electrical lines is disclosed in two embodiments. Both embodiments are shaped to give visibility from all angles and to allow smooth covering with retroreflective tape. One embodiment includes a continuous burning interior light for maximum nighttime visibility.

Abstract: An intermediate voltage or cable marker with a gas filled lamp with reflectively enhanced conspicuity comprising an inner conductive coating in an opaque shell; the shell being mountable on an the intermediate voltage line and having one end of the gas filled lamp electrically connected to the intermediate voltage line or grounded cable and the other end electrically connected to a electrical coil in series with the conductive inner shell coating; the gas filled tube being mounted in a reflective chamber shaped to increase both lateral and vertical conspicuity.

Abstract: An impact recovery delineation system comprises a base member that provides improved mechanical and chemical bonding to the road surface and a portable base that provides a rigid center portion and flexible ends to maintain the position of the delineator device after vehicle impact. A sealed, pneumatic tube of high impact resistant material composition acts as a delineator post and is adapted to receive modified load cells. Upper and lower load cell elements are provided with cable passages to allow side-by-side placement of wire rope cables. The passages are particularly geometrically configured and have two radiused edges and two straight edges which result in rapid bending and recovery of the delineator post system upon high speed impact, in any direction, by an automotive vehicle. A vented signage panel having air vents therein to reduce wind resistance, improve and speed recovery of the impacted system.

Abstract: An illuminated aerial marker for a high voltage transmission line using a spherical colored opaque capacitor with gas filled lamps electrically connected, exterior to the capacitor with one electrode of the lamps connected to the high voltage source and the other to the conductive area of the capacitor or capacitors. The lamps are spaced and sized to provide illumination with nighttime conspicuity of at least 4,000 feet when the lamps are activated.
