Abstract: An auxiliary heating means for improving the melting efficiency of melter kettles used to melt thermoplastic pavement marking materials. The auxiliary heating means includes a tube assembly through which thermoplastic material received from the bottom of the melter kettle is transferred to the top of the melter kettle. The tube assembly comprises an odd number of tubes having augers therein. The tube assembly is coupled to a side portion of the melter kettle and located within a heat chamber through which hot combustion gases from a combustion chamber at the bottom of the melter kettle flow and transfer heat into the tube assembly. The heat chamber comprises an extended portion of a heat chamber that surrounds the melter kettle.

Abstract: An auxiliary heat exchanger that is used in conjunction with thermoplastic melter kettles. The auxiliary heat exchanger receives molten thermoplastic material from the bottom of a melter kettle, transports the molten thermoplastic material though the auxiliary heat exchanger and feeds the molten thermoplastic material into the top of the melter kettle thereby mixing hotter molten thermoplastic material from the bottom of the melter kettle into cooler thermoplastic material near the top of the melter kettle. The auxiliary heat exchanger includes an oil bath chamber and parallel heat transfer tubes that are arranged in a serpentine configuration and include motor drive augers to transport molten thermoplastic material through the auxiliary heat exchanger.

Abstract: An auxiliary single-pass tube bundle heat exchanger for improving the melting efficiency of melter kettles used to melt thermoplastic pavement marking materials. The auxiliary single-pass tube bundle heat exchanger includes a heat transfer tube bundle having a plurality of heat transfer tubes in which the flow of molten thermoplastic material reverses directions at least once. Hot heat transfer oils flows around the plurality of heat transfer tubes. Vertical material transfer tubes connect between the bottom of the melter kettle and the top of the auxiliary single-pass tube bundle heat exchanger and between the bottom of the auxiliary single-pass tube bundle heat exchanger and the top of the melter kettle. Augers within the vertical material transfer tubes driven by reversible drive motors cause molten thermoplastic material to flow from the bottom of the melter kettle, through the auxiliary single-pass tube bundle heat exchanger, and into the top of the melter kettle.

Abstract: A molten thermoplastic circulation system that is used in conjunction with thermoplastic melter kettles. The molten circulation system includes a vertical material transfer tube that is coupled to a melter kettle and includes an auger. The vertical material transfer tube is coupled to the top and bottom of a melter kettle so as to transfer molten thermoplastic between the bottom and top of the melter kettle. The vertical material transfer tube is at least partially surrounded by a heat chamber through which a heated fluid such as hot combustion gases or heated oil can flow. In use molten thermoplastic material that is heated at a higher temperature at the bottom of a melter kettle near the combustion chamber is transferred through the vertical material transfer tube to the top of the melter kettle to improve melting efficiency.

Abstract: A material-removal system can include a spray-head assembly with a plurality of rotatable fluid bars arranged in a single shroud with overlapping sweeps. A gear-box assembly can index the rotations of the fluid bars to coordinate their rotation and prevent the fluid bars from interfering with one another. The material-removal system can be mounted on a mobile platform, such as a vehicle. The vehicle can have a fluid-storage tank and a debris tank that can be tilted for dumping operation while the fluid-storage tank remains stationary. A peristaltic pump can advantageously remove liquid waste from the debris tank while a vacuum system has the debris tank operating under vacuum. The spray-head assembly can be coupled to the vehicle with an articulating-arm assembly that can include a four-bar mechanism and a pair of rotary actuators to facilitate vertical and rotational movement of the arm assembly and the spray-head assembly.

Abstract: A material feed system for melter kettles which provides an area for a tender to load material to be charged into a melter kettle at a location which is safely remote from a flame conductor assembly that allows any flames or gasses that build up in melter kettle to be released. The material feed system also includes an air intake duct through which free air is allowed to enter into the melter kettle so as to equalize pressure with the atmosphere and/or burn off any superheated material.

Abstract: Non-ridable and non-motorized machines for removing temporary tape that include a chassis or frame having front and rear wheels, a vertical support post mounted on the frame or chassis between the front and rear wheels, a horizontal arm mounted on the vertical support post, and a rotatable spool assembly attached to one end of the horizontal arm for winding used temporary tape thereon, wherein the horizontal arm is rotatably coupled to the vertical support to allow the spool assembly to be positioned on either side of the chassis when the horizontal arm is rotated with respect to the vertical support post. The non-ridable temporary tape removal machine can be manually and guided along a pavement during a tape removal operation. The non-motorized temporary tape removal machines can be or coupled to an auxiliary motorized device that pushes the non-motorized temporary tape removal machine during a tape removal operation.
