404095000 | With means for heating a road base, surface, or material | 9 |
20080292401 | Heated drum compactor machine and method - A compactor machine includes a frame and at least one compactor drum mounted to the frame. The at least one compactor drum has an outer surface configured for compacting asphalt. A heating system is configured to heat the outer surface and includes a control device configured to control an output of the at least one heating element to the outer surface. A related method for providing a heated drum for a compactor includes mounting at least one heating element and a control device for the at least one heating element to a compactor machine, and coupling the control device with the at least one heating element to enable controlling an output thereof to an outer surface of the compactor drum. | 11-27-2008 |
20090087264 | Cement Heating and Finishing Machine - The cement finishing machine ( | 04-02-2009 |
20090257825 | Heating Control System for A Screed - A control system for heating a screed assembly of a paving machine is provided. The control system includes a plurality of resistive heating elements positioned adjacent to a screed plate of the screed assembly. An electrical power supply is selectively connected with the resistive heating elements via switches operated by a controller. The controller is responsive to inputs from at least manual switches and temperature sensors. The controller is configured to automatically adjust the temperature of the screed plate by selectively energizing fewer than all of the resistive heating elements at a time. | 10-15-2009 |
20090311046 | Reflector apparatus, heating system, kit and method - A reflector apparatus including a mobile trailer and a heat reflector attached thereto such that terminal edges of wings of the reflector are disposed proximate to the surface of the heated asphalt and define a plane that is substantially parallel to a plane formed by the surface of the heated asphalt. A kit includes a heat reflector and a mechanism or device for removably attaching the heat reflector to a mobile trailer. | 12-17-2009 |

20100310312 | ROAD FINISHING MACHINE - The invention relates to a road finishing machine having a screed extending transverse to the working direction of the finishing machine, comprising a base plate that can be heated by means of an electrical heater clamped to the base plate, comprising at least one bar-shaped heating element, wherein the bar-shaped heating element comprises a round tube heating element comprising at least one heating bar fixably supported on individual bolts that can be attached to the base plate and forming heat transfer bridges. | 12-09-2010 |
20130071184 | ASPHALT RECYCLER AND HEAT MANAGEMENT APPARATUS - The present invention generally relates to a portable asphalt recycling and asphalt heat management apparatus comprising a seamless vacuum-formed one-piece combustion chamber that defines a fuel incubator disposed therein. A heat accumulator is operably coupled to the combustion chamber and a hopper assembly is operably coupled to the heat accumulator. The apparatus further comprises a heat distribution system in communication with the heat accumulator and the hopper assembly to provide heat the to the hopper assembly for recycling used asphalt or for maintaining a mixture of asphalt for use in asphalt repairs. | 03-21-2013 |
20150037097 | Road Finisher, Screed Plate, And Tamper Bar Comprising A Heating Element And Method To Manufacture The Same - The present invention relates to a road finisher comprising a screed plate and/or a tamper bar and also to a screed plate and/or tamper bar comprising a heating layer applied by thermal spraying. | 02-05-2015 |
20160123586 | BURNER UNIT HAVING A LOW VOLTAGE SENSOR - A combustible fuel burner system includes a burner unit, a power source, and a circuit interrupter unit. The circuit interrupter unit has a switch electrically coupled between the power source and the burner unit. The switch has a closed state, wherein the burner unit receives operational electrical power from the power source. The switch moves from a closed state to an open state and electrically disconnects the device from the power source upon a voltage of the power source falling below an interruption threshold. The switch, when in the open state, moves to the closed state upon the voltage of the power source being above a restoration threshold that is higher than the interruption threshold. | 05-05-2016 |
