431157000 | MEANS AT CHAMBER OUTLET ESTABLISHING COMBUSTION PRESSURE DISTINCT FROM AMBIENT | 6 |
20140242529 | TORCH AND TORCH ATTACHMENT - An attachment for a torch includes a combustion cone mounted on a fuel delivery tube. The combustion cone bounds a combustion chamber and has an inlet through which fuel from the tube enters the chamber to create a flame when the torch ignites the fuel. The cone diverges away from the inlet and to an outlet to enable the flame to diverge and spread within the chamber. The chamber substantially contains the flame therein. At least one apertured radiator, and preferably, a pair of apertured radiators, is mounted in the chamber in direct contact with the flame, and heated by the flame to a temperature sufficient to cause each radiator to radiate infrared radiation through and past the outlet. A tipping-resistant holder holds a fuel canister of the torch upright when placed on a support surface. | 08-28-2014 |
431158000 | Chamber outlet forms jet nozzle | 5 |
20120288808 | HOT AIR GENERATOR BURNER WITH INTERCHANGEABLE LIGHTER - A heat-shrink gun in which an ignition voltage of the gaseous mixture is generated by a piezoelectric lighter ( | 11-15-2012 |
20120288809 | HOT AIR GENERATOR DEVICE WITH IMPROVED LIGHTING - A hot air generating device of the type including an injection device ( | 11-15-2012 |
20130089824 | Heating And Cleaning Apparatus For Surface Treatment - A heat gun for cleaning and heat treating surfaces uses a lightweight jet engine to generate a hot blast of exhaust, with aggregate injectors in an engine jacket arranged over the jet engine admixing a cleaning medium with the hot exhaust. The cleaning medium admitted into the hot exhaust jet is discharged through an exhaust nozzle 1 directed at the item to be treated. The engine is controlled electronically and advanced on a lightweight frame | 04-11-2013 |
20130196274 | UNDERWATER TORCH - A underwater cutting torch having a control valve assembly, a check valve assembly and a torch head all positioned within a housing. The control valve assembly and check valve assembly include a passageway for gasses to flow that includes a coupler formed of PTFE material to inhibit combustion within the handle of the underwater cutting torch. | 08-01-2013 |
20140322659 | Heating Apparatus And Method For Treatment Of Weeds - A heat gun for treating a surface to destroy weeds and unwanted vegetation uses a lightweight jet engine to generate a hot blast of combustion exhaust, with an optional injector in an engine jacket arranged over the jet engine admixing water with the hot exhaust. The combustion exhaust is discharged through an exhaust nozzle and directed by a shield downwardly into contact with the surface to be treated. The engine is controlled electronically and advanced on a lightweight frame, which may be fitted with a ballast weight and spacer wheels, or be mounted on an advancing arrangement. The jet engine is powered by liquid fuel supplied from a tank. Intake air is cleaned and sound-damped in a filter unit. Combustion takes place at a high pressure and the exhaust discharged hot in a high velocity exhaust stream which instantaneously destroys weeds and unwanted vegetation in the soil contacted therewith. | 10-30-2014 |
