Abstract: A device and system comprising a cutting torch system including a multi-fuel adapter specially adapted to convert a gasoline oxygen cutting system to a multi-fuel cutting system and methods of using the same. The invention also includes a portable system including a carrying case for use with the multi-fuel adapter.

Abstract: A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.

Abstract: The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOx storage catalysts.

Abstract: The invention relates to a method and apparatus for temperature control of a gas-heated evaporator according to DIN standard 30 696, which for attaining, keeping constant, and limiting a predetermined operating temperature is equipped with heating and control elements.

Abstract: This invention relates to a kerosene vapor stove with an automatic fuel feeding system. There are two ways of vaporizing the kerosene. When the stove is about to be lighted, kerosene is channelled into a preliminary preheating tube to be heated up to a high temperature within a short time. The heated kerosene under pressure passes through a nozzle and shoots through an air gap into a mixing tube, vaporizing in the process. The mixture of the kerosene vapor and air is delivered into a burner where it burns. After the stove has been lighted for about two minutes, the loop of tube above the burner will be well heated. This tube is a part of the normal path for kerosene. Kerosene is now channelled through this tube for preheating, utilizing the heat produced by the burner to effect vaporization. The automatic feeding of the kerosene is accomplished through using a steel container containing kerosene up to 80% of its volume. A tube extends from the outlet valve of the container down to its bottom.

Abstract: This invention combines specific new and novel equipment with the equipment of a conventional combustion system for the use of liquid fuel oil to create a new system which converts the liquid fuel into gas and operates as a gas burner rather than as a liquid oil burner. The new and novel equipment thermally cracks liquid hydrocarbons into gaseous hydrocarbons which have substantially lower molecular weights than the liquids from which they were cracked. In the system the burner apparatus itself is modified to burn gas rather than liquid. In this new system the fuel burned does not consist of vapors of the liquids supplied to it but instead operates on the products of decomposition derived from the liquids.
