    Abstract: A lance for spraying particulate refractory-forming combustible material, particulate refractory material and a comburent gas is characterized in that the lance 1 comprises at least one feed passage 2,3 for conveying material to be sprayed to a lance head 4 which comprises a plurality of spray nozzles 5 for spraying such material, and in that the flow path of the material being sprayed branches or turns a corner and a cup-like recess 7,9 is located at the or each such branch or corner, open to the flow path upstream thereof, for catching particulate material conveyed along said flow path so that the material caught itself forms a barrier against abrasion at the location of such recess.A method of using such a lance to spray particulate refractory-forming combustible material, particulate refractory material and a comburent gas against a surface so that on combustion a coherent refractory mass is formed on such surface is also disclosed.

    Abstract: There is provided an improved powder flame spraying apparatus and method having a preheating nozzle in advance of a plurality of final heating nozzles into the converging flame envelopes of the latter of which hardfacing powder is dispensed. This powder is aspirated into a pressurized stream of inert gas at a variable rate readily adjusted between maximum and no-flow by selectively regulating the gas pressure at and/or spaced downstream from the outlet of the powder aspirator. Regulation of the gas pressure is achieved by venting variable quantities of gas to the atmosphere or air to the aspirator outlet as appropriate to provide a desired powder flow and to achieve a desired volume and velocity of gas and powder delivery into the final heating flames.

    Abstract: The invention contemplates a gas-torch construction wherein independent flows of combustible gases are maintained up to the point of mixing within the nozzle of the torch, virtually at the location of discharge from the nozzle. The nozzle is removably connected to an elongate intermediate or adapter member, and the latter is removably connected to the torch body. The separate flows of the gases are maintained independent of each other, from the torch body, through the adapter member, and into the upstream end of the mixing nozzle. Individual radially spaced manifolds at the adapter-to-nozzle connection assure independence of the gas flows and a non-critical angular relation when the nozzle is replaced. The invention is described in application to a powder-spraying gas torch, as for torch deposition of metal coatings.

    Abstract translation: 本发明考虑了一种气体割炬结构，其中可燃气体的独立流量维持到喷枪喷嘴内的混合点，实质上在从喷嘴排出的位置处。 喷嘴可移除地连接到细长的中间或适配器构件，并且后者可拆卸地连接到割炬本体。 气体的单独流动彼此独立地保持，从割炬本体通过适配器构件，并进入混合喷嘴的上游端。 在适配器与喷嘴连接处的各个径向隔开的歧管确保了气体流的独立性和更换喷嘴时的非临界角度关系。 本发明描述为适用于粉末喷射气体割炬，用于金属涂层的火炬沉积。
