摘要： Disclosed is a method for enriching combustible gas, which suppresses the deterioration and pulverization of an adsorbent without extending a period for pressure equalization. The pressure equalization is effected by opening a pressure equalization passage opening/closing valve incorporated in a pressure equalization passage, after completion of adsorption in a first adsorption tower and after completion of desorption in a second adsorption tower connected to the first adsorption tower via the pressure equalization passage.

摘要： A method of and apparatus for automatic or semi-automatic welding or brazing wherein a fillet-wire, mechanically fed to the welding position on a work piece, is heated, along with the work piece, by a flame so that the fillet-wire reaches its melting point. A heating current is supplied to the fillet-wire to flow between the wire and the work piece. In order to maintain a predetermined relationship between the rate at which the fillet-wire is fed to the work piece and the rate at which the wire melts and separates to drop onto the work piece, the feed-rate and/or current intensity is regulated such that the wire is in constant contact with the work piece with a predetermined contact pressure. In one embodiment, the mechanical feeding device comprises a torque-limiting mechanism to maintain a substantially constant predetermined contact pressure of the fillet wire against the work piece. The torque-limiting mechanism may be of the slippage-type with two friction clutch-discs driven by a motor shaft, or it may be of the iron-powder type that is electrically operated.

摘要： The invention relates to an improved method of automatic or semi-automatic welding with gas, or brazing, effected by using a coil of fillet wire brought to the welding point by continuously passing through the center of a gas flame, (oxy-acetylene, oxygen-propane for example) which melts the wire and heats the work part, said improvement comprising the application of an electrical voltage between a member mounted on the forward-movement path of the fillet wire and the work part under treatment, so as to cause the passage therein of a heating current.The electrical voltage is preferably applied either between the welding torch nozzle or the forward-movement rollers and the part treated.
