摘要： Disclosed herein is a device for cutting a pipe from the inside by the oxy-arc cutting technique. This device comprises, in combination, guide means for guiding the device proper inside a pipe subjected to cutting, fixing means provided with a plurality of claws adapted to be thrust radially from a cylinder in the direction of the inner wall of the pipe by the action of a piston actuated by the supply of a compressed fluid to the cylinder so as to hold the device immovable in position inside the pipe, and oxy-arc cutting means for cutting the pipe from the inside by the use of a covered hollow stick cutting rod rotated by a rotary shaft pierced through the center of the piston, with the exposed core of the cutting rod held in sliding contact under a fixed force with the inner wall of the pipe.

摘要： The slag formed when concrete is melted by exposure to a laser beam, when caused to incorporate therein a MgO-rich supplementary material, loses it viscosity and, on cooling, refrains from expanding and, consequently, assumes a readily removable state. The slag thus set can be easily removed by allowing a cleaning device such as the rotary wire brush to pass along the part of concrete melted by the laser beam. In accordance with this method, the apparatus for cutting concrete can be readily applied to a remote control system and will manifest an outstanding effect in a highly hazardous site such as is involved in the dismantling of a biological shield wall of concrete in a nuclear reactor.
摘要翻译：当混凝土通过暴露于激光束熔化时形成的炉渣，当其中掺入富含MgO的补充材料时，其失去粘度，并且在冷却时不会膨胀，并因此呈现易于移除的状态。通过允许诸如旋转钢丝刷的清洁装置沿着由激光束熔化的混凝土的部分通过，可以容易地去除由此设定的炉渣。根据这种方法，用于切割混凝土的装置可以容易地应用于远程控制系统，并且将在高度危险的场所中表现出显着的效果，例如涉及在核反应堆中拆除混凝土的生物屏蔽壁。

摘要： A process of making a hole in a metal material of a large thickness comprises bringing the tip of an arc electrode wire into contact with the metal material while laterally reciprocating the arc electrode wire to thereby form an entry path on one side of the arc electrode wire and an exit path on the other side of the arc electrode wire within the hole, and causing a pressurized fluid to be introduced into the entry path, guided to the bottom of the hole and the exit path, and discharged out of the hole together with the molten metal lumps.

摘要： Gas cutting of a plate material such as of stainless steel or stainless-clad steel is efficiently carried out by advancing a cutting torch along a mild steel bead formed on the material by melting thereon mild steel using a welding torch. When the material preheated in advance is burnt by directing a jet of oxygen thereto, the mild steel bead on the material effects to elevate the combustion temperature, thereby allowing refractory slag produced in cutting to be fused and blown off by virtue of the jet of oxygen.

摘要： In the consumable-electrode type arc cutting process whereby the work subjected to cutting is fused and severed by means of a continuous electric arc formed between the wire electrode protruding from the contact tip and the work, an improvement is obtained by the additional utilization of a jet of high-pressure water projected out of a water projection nozzle disposed on the outside of the contact tip. The jet of high-pressure water projected from said nozzle is directed to the point of arc formation on the work so as to blow the molten metal of the work away, whereby the severed edges of the work are prevented from being joined again and, at the same time, the dross is prevented from being deposited on the work and consequently the cut edge of the work is finished neatly.
