AI Technical Summary

Problems solved by technology

Jets of unignited pressurized gas can pose a serious safety hazard, rapidly releasing dangerous quantities of flammable gases into the air
Gas burner flames can be pale and difficult to see, especially in bright light, making it difficult for mobile applicator operators to determine whether the gas jet is ignited (and therefore safe) or not (and therefore potentially dangerous )

Abstract

A flame safety system for a thermoplastic applicator comprises a gas burner and a flame indicator. The gas burner expels a jet of pressurized combustible gas from an outlet nozzle, and includes an attachment groove near the nozzle. The flame indicator includes an attachment ring configured to fit into the groove, thereby securing the flame indicator to the gas burner, and a flame path portion extending from the attachment ring into the jet of pressurized combustible gas. The flame path portion is formed from a material which incandescently glows whenever the jet of combustible pressurized gas is lit.

Description

technical field [0001] The present invention relates generally to a flame safety, and more particularly to a flame indicator for use in a mobile applicator for marking paved roads using thermoplastics. Background technique [0002] Alkyd and hydrocarbon thermoplastics are commonly used to mark paved road surfaces with visible lines or symbols such as road dividers and guide lines. In particular, thermoplastics offer a durable alternative to pavement paint and are commonly used to mark road intersections, parking lots, and other high-traffic paved surfaces where paint can quickly ground was worn away. [0003] Thermoplastics are typically applied to pavement using a mobile applicator that includes a heated reservoir or kettle and an application screed die. Molten thermoplastic is dispensed from the kettle at a controlled rate and applied in thin layers to the paving surface using a screed die. Some coaters also include auxiliary burners which heat an auxiliary reservoir or...
