A. Where the sides of the boiler are flat, instead of being cylindrical, a sufficient number of stays must be introduced to withstand the pressure; and it is expedient not to let the strain upon these stays be more than 3,000 lbs. per square inch of section, as the strength of internal stays in boilers is generally soon diminished by corrosion.
Inside it was warm and bright and home-like; outside it was twenty degrees below zero, and like some vast tomb where life itself was congealed, and only the white stars, low, twinkling, and quizzical, lived-a life of sharp corrosion, not of fire. Suddenly she raised her head and listened. The dog did the same.
It has become that transitional form between image and pure concept that we now term "generic image," or one that at least resembles the latter. The image, then, is subject to an unending process of change, of suppression and addition, of dissociation and corrosion. This means that it is not a dead thing; it is not at all like a photographic plate with which one may reproduce copies indefinitely.
If pure blood comes out, as if a vein were opened, some corrosion or gnawing of the womb is to be feared. All these are known by the following signs: The place of conception is continually moist with the humours, the face ill-coloured, the party loathes meat and breathes with difficulty, the eyes are much swollen, which is sometimes without pain.
Indeed, a strain at all approaching that upon locomotive boilers would be very unsafe in the case of marine boilers, on account of the corrosion, both internal and external, to which marine boilers are subject.
He did not make the figure a ruler should as he sat in his easy chair, and whined and cursed his Swiss. He was scarce a year over forty, and he had all but run his race. Dissipation and corrosion had set their seal upon him, had stamped his yellow face with crows' feet and blotted it with pimples.
The days were coming when the People was to have more to say than the pope in regard to the disposition and arrangements of certain large districts of this planet. While the world-empire, which still excited so much dismay, was yielding to constant corrosion, another empire, created by well-directed toil and unflinching courage, was steadily rising out of the depths.
If the safety valve of a boiler be accidentally jammed, or if the plates or stays be much worn by corrosion, while a high pressure of steam is nevertheless maintained, the boiler necessarily bursts; and if, from an insufficiency of water in the boiler, or from any other cause, the flues become highly heated, they may be forced down by the pressure of the steam, and a partial explosion may be the result.
No more effervescence and hissing tumult as he pours his sharp thought on the world's biting alkaline unbeliefs! No more corrosion of the old monumental tablets covered with lies! No more taking up of dull earths, and turning them, first into clear solutions, and then into lustrous prisms! I, the Professor, am very much like other men: I shall not find out when I have used up my affinities.
As to this ugly feud opening between his mother and his wife, it had quite ceased to amuse him. Now that his marriage was a reality, the daily corrosion of such a thing was becoming plain. And who was there in the world to bear the brunt of it but he? He saw himself between the two eternally trying to make peace and his face lengthened.
