摘要： First regenerators (3A-3C) which are in combustion exhaust gas exhaust passages, second regenerators (4A-4C) which are in suction/recovery passages for sucking and recovering N2, an atmospheric gas, are provided to three or more regenerative heaters (1A-1C), respectively. In one (1C) of the regenerative heaters (1A-1C), the sucked N2 atmospheric gas is passed through the second regenerator (4C) to regenerate its sensible heat. In another one (1A), combustion air is passed through the second regenerator (4A) in which the heat is stored and combustion is carried out by using the heated air. Only the combustion exhaust gas is passed through the first regenerator (3A) for regeneration. In the other one (1B), the N2 atmospheric gas is passed through the first regenerators (3A-3C) in which heat is regenerated to convert the regenerated heat into sensible heat, which is supplied to the atmosphere of an object and heats the object. These processes, i.e. combustion, atmospheric gas heating and atmospheric gas suction, are repeated in this order. Thus, the atmospheric gas is recovered and reused, and the sensible heat of the atmospheric gas is converted into the sensible heat of the combustion air to improve the heat efficiency.

摘要： The long-fiberglass reinforced polyolefin moldings according to the prior art were poor in weathering resistance, though excellent in mechanical strengths. They were also liable to lower in the mechanical characteristics when they contained colorants. The present invention provides long-fiberglass reinforced polyolefin moldings excellent in both weathering resistance and mechanical strengths, compositons useful as the raw material therefor, and further moldings which are not impaired in either of the above properties even when they are colored and compositions useful as the raw material therefor. Specifically, the compositions at least comprise (A) long-fiberglass reinforced polyolefin pellets which are produced by impregnating a glass fiber roving with a polyolefin and cutting the resulting roving in lengths of 2 to 150 mm and have a fiberglass content of 10 to 90 wt.% and wherein the glass fibers contained are arranged in a length substantially equal to that of the pellet, (B) a light stabilizer and (C) a light absorber, and are characterized in that the total amount of the components (B) and (C) is 0.25 to 7.5 parts by weight per 100 parts by weight of the whole polyolefin; and long-fiberglass reinforced polyolefin moldings at least comprising (a) a polyolefin, (b) a fiberglass having a fiber length of 2 to 150 mm, (B) a light stabilizer and (C) a light absorber, characterized in that the total amount of the component (B) and (C) is 0.25 to 7.5 parts by weight per 100 parts by weight of the whole polyolefin and that the fiberglass content is 10 to 90 wt.%. The above moldings can keep both of the above properties at high levels even when colored black with carbon black or gray with carbon black and zinc sulfide, as far as the colorant(s) is added at a specific ratio to the above additives.

摘要： Iron powder and iron-base powder mixture for powder metallurgy, which can provide sinters excellent in machinability and wear resistance. The iron powder contains 0.03-0.3 wt.% boron, at most 0.07 wt.% chromium, less than 0.3 wt.% manganese, and the balance consisting of iron and unavoidable impurities, and has an intensity ratio of boron to iron of at least 0.05 in the spectrum of the powder surface as determined by Auger electron spectroscopy. The powder serves to increase the amount of graphite remaining in sinters to thereby improve the machinability and wear resistance thereof. Another iron powder is prepared by adding sulfur, selenium, tellurium, molybdenum or the like to the above powder. These powders are mixed with MoO3 or WO3 powder to develop a so-called iron-base powder mixture. It is produced by water-atomizing the above powders while adjusting the oxygen content of molten steel to 100 ppm or below.
