Sun-driven Engine

1.     It is common knowledge that certain metals and their alloys are attracted by a magnet. After heating, this property vanishes; it is restored after cooling down. A new magneto-heat engine works on this principle. This invention relates to devices which transform thermal power, for instance, the power of the sun rays, into a mechanical power of rotation.

2.     The rotor of the new engine is made of an alloy that loses its magnetic properties already at 100 C. If the rotor is heated on one side, the cold side of the rotor will turn toward the magnet. Since heating continues, the rotor goes on rotating, too. Thus solar power can be used as a source of heat in this case. The magneto-heat engine can drive pumps in waterless districts, it can also be widely used for watering greenery in cities and settlements.

1.     All the industries today are in need of new methods of joining metals together. And not only metals with metals but also joining metals with glass, plastics and many other materials. The work done by the Paton Institute of Electric Welding is considered to be the solution of these problems. For example, how to weld a 1,000 km-long pipeline? The Institute has developed a machine for welding pipelines. The welding section in each pipe exceeds 100,000 sq. mm. It would take 6-8 hours to perform this work by hand. The machine does it in two minutes.

2.     The machine was tested in production conditions, the results being excellent.

4.         The rapid development of the oil and other mineral resources of the ocean made the problem of underwater welding especially up-to-date. The semi-automatic machines for underwater welding increased divers productivity by 25-30 times.

5.     And what about welding in outer space? The scientists understood that welding had to be done in conditions of weightlessness, in nearly complete vacuum and within a broad range of temperatures from 150 C below to 130 C above zero. The equipment, of course, must be reliable and safe

V. Прочитайте 5-ый абзац текста и ответьте письменно на следующий вопрос:

            What are the conditions of welding in space?
