If you blow ordinary steam at 212° F. or 100° C., into fats or oils, the fats and oils remain undecomposed; but suppose you let fatty and oily matters of animal or vegetable origin, such as lubricants, get into your boiler feed-water and so into your boiler, what will happen?
Glucea dextrina paste is used as a substitute for india-rubber. These products of the maize, other than its grain, are employed in the preparation of preserves, syrup, beer, jams, sweets, and drugs, and in the manufacture of paper, cardboard, mucilage, oils and lubricants, paints, and many other things. The imitation india-rubber promises to be the basis of a most important industry.
Ashton-Kirk rang the bell here, and while they waited a man who had been seated in the open door of the machine shop got up and approached them. He wore blue overalls and a jumper liberally discolored by plumbago and other lubricants; a short wooden pipe was held between his teeth, and a cloth cap sat upon the back of his head. "Looking up the Dago?" asked he with a grin.
They must also be kept free from oil or any kind of grease, as all lubricants of that sort will harden and prevent the working of the lock.
Eventually Roger found a location which satisfied his requirements of raw materials, and made a landing upon that unfriendly soil. Sweeping beams denuded a great circle of life, and into that circle leaped robots. Robots requiring neither rest nor food, but only lubricants and power; robots insensible alike to that bitter cold and to that noxious atmosphere.
Paraffin oil and petroleum we obtain from coal, whilst candles, oils, dyes, lubricants, and many other useful articles go to attest the importance of the underground stores of that mineral which has well and deservedly been termed the "black diamond."
This latter deserves special mention, not only because of its arrangement for thorough lubrication, but also on account of the resultant economy affecting the cost of manufacture. Edison has strong convictions on the liberal use of lubricants, but argued that in the ordinary oiling of machinery there is great waste, while much dirt is conveyed into the bearings.
Doctors explain to us that the immediate cause of insomnia is always some poisoned or depleted state of the body, and no doubt the fatigues and hasty meals of the day had left the bishop in a state of unprecedented chemical disorder, with his nerves irritated by strange compounds and unsoothed by familiar lubricants.
Benzol from byproduct coking ovens also can be used, but quantitatively is totally inadequate. For kerosene no quantitative substitute is known. Lubricants can be obtained from animal and vegetable fats, but mostly are inferior in quality, and there seems no hope of obtaining them in quantity.
