20080210215 | ROOF DEICER FOR ROOFS HAVING ACCESSIBLE SIDES - A heating system particularly adopted to prevent winter mix accumulation on boat dock roofs which is intended to be retro fitted to an existing roof structure is provided in which a panel is mounted to the an accessible second side of the roof in heat transfer relationship with the roof so as to enable the panel to transfer heat from the panel to the external facing side of the roof. | 09-04-2008 |
20120085337 | SOLAR POWER GROUND ENGAGEMENT DEVICE WITH AN ECOLOGICAL ENVIRONMENTAL PROTECTION FUNCTION - A solar power ground engagement device with an ecological environmental protection function primarily consists of a tube which has a drainage function and is combined with a water accumulating box at its bottom; a power gatherer is provided at the interior of the tube which is engaged into the ground paving and goes through to the macadam beneath the paving, such that the paving would serve as a water permeable ecological paving to allow the rain accumulated on the ground to instantly permeate into the underground, and concomitantly allow the macadam to keep a high content of water to enhance generation of microbe and activation of the soil; in addition, the power gatherer in the tube can absorb the solar power to develop a condensing or heat gathering function to accomplish regulation of the integral temperature and humidity of the environment. | 04-12-2012 |
20120180778 | MULTIPLE FUEL TANK SYSTEM - The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls. | 07-19-2012 |
20140020672 | Thermal Cloth, In Particular for Football Fields - Thermal cloth for football fields, comprising: a polyvinyl chloride sheet; an electrical heating resistor cable glued on top of said polyvinyl chloride sheet according to predetermined pattern and distances; an aluminium sheet glued on top of said polyvinyl chloride sheet and of said heating resistor cable; a control system for supplying said heating resistor cable; said thermal cloth is positioned on said football field with said aluminium sheet placed upwards. | 01-23-2014 |
20150034067 | FROST RESISTANT SURFACE - Methods, systems and devices for making a surface resistant to frost are disclosed. | 02-05-2015 |

20120199111 | Hot water snow removal system - This system is based on a provisional patent by the inventor Darrell E. Heard, Application No. 61/462,729, a hot water snow removal system wherein the system employs a salt specifically suitable for the disintegration of snow. In this system there are a series of components in the form of Appliances inline necessary to achieve the task of hot water snow removal. The first tank on page one, is a hot water heater, followed by a reduced pressure zone backflow preventer, connected to a salt processing apparatus, a heat pump, hot water storage tank, thermal fluid collector timing mechanisms, heat pump and hot fluid circulation manifold and sprinkler system. Its purpose is to prevent line freeze up at the sprinkler heads and in the sprinkler systems lines. | 08-09-2012 |
20130312733 | Ground Excavation Preparation System - A ground excavation preparation apparatus for thawing a frozen ground surface prior to excavation, consisting of a trailer; a housing connected to the trailer; mobility means attached to the trailer for moving the apparatus; heat generation means above the housing for supplying thawing energy; heat distribution means within the housing for transferring heat into the ambient air within the housing; and hydraulic means connecting the trailer to the housing for raising and lowering the housing at an excavation site. | 11-28-2013 |
20140216437 | HYDRONIC SURFACE HEATING SYSTEM - A mobile surface heater is disclosed having a heat generation loop and a heat dissipation loop. The heat generation loop can include a heat generating device, a storage tank, and a first pump for circulating a fluid. The heat dissipation loop can be placed in fluid communication with the heat generation loop and includes a ground heating system having at least one heat transfer conduit extending between a supply manifold and a return manifold. A control valve can also be provided to deliver a mixed fluid flow stream to the ground heating system by selectively mixing fluid from the heat generation loop with fluid returning from the ground heating system return manifold. In one embodiment, an electronic controller is provided that operates the mixing valve to maintain a temperature setpoint of the mixed fluid flow stream and to maintain a minimum entering fluid temperature setpoint of the atmospheric water heater. | 08-07-2014 |
20220136456 | SCROLL HEATING DEVICE - A scroll heating device includes a base, a reaction region, and a first and a second channel. The reaction region is at the center of the base. The two channels are located on the base and extend spirally from the reaction region toward the periphery of the base. The width of each channel is gradually reduced as the channel extends from adjacent to the center of the base toward the periphery of the base. The first channel allows a gas that flows into the first channel through the periphery of the base toward the center of the base to flow toward the reaction region at a progressively slower rate, enter the reaction region slowly through the gradually widening first channel, and therefore stay in the reaction region for longer. The combusted exhaust enters the second channel from adjacent to the center of the base and exits through the periphery of the base. | 05-05-2022 |

20110120443 | DIRECT FIRED AXIAL FLOW CO-CURRENT HEATING SYSTEM FOR HOT-IN-PLACE ASPHALT RECYCLING - A direct fired, axial flow, co-current primary heater for use in a hot in place asphalt recycling system includes internally substoichiometric inspiriting burners operating at slightly greater than the stoichiometric amount by tertiary air flow controlled by a variable speed induced draft fan. A cool down box at the end of the burner box reduces emissions exiting at the back of the system. The sides of the burner box may pivot outwardly to increase the width of coverage. | 05-26-2011 |
