"Chemical process" Quotes from Famous Books



... alternation increases, they become not more dangerous but less so. It further appears that a true flame can now be produced without chemical aid—a flame which yields light and heat without the consumption of material and without any chemical process. To this end we require improved methods for producing excessively frequent alternations and enormous potentials. Shall we be able to obtain these by tapping the ether? If so, we may view the prospective exhaustion of our coal-fields with indifference; we shall at once solve the smoke question, ...

... lapidary. The inclosing rock must have been as thickly vesicular in its original state as the scoria of a glass-house; and all the vesicles, large and small, like the retorts and receivers of a laboratory, have been vessels in which some curious chemical process has been carried on. Many of them we find filled with a white semi-translucent or opaque chalcedony; many more with a pure green earth, which, where exposed to the bleaching influences of the weather, exhibits a fine verdigris hue, but which in the fresh fracture ...

... consumed the instant it is generated (except in rare instances where small amounts are accumulated in storage batteries by a chemical process). The pressure of a button, or the throw of a switch causes the dynamo instantly to respond with just enough energy to do the work asked of it, always in proportion to the amount required. Having this in mind, it is rather curious to think of electricity as being an article ...
— Electricity for the farm - Light, heat and power by inexpensive methods from the water - wheel or farm engine • Frederick Irving Anderson

... water-power forgets that society is not a machine; that it was not made to order like a newspaper editorial, and that to attempt by a radical process to make it other than what it is—to change its genius arbitrarily—were as fatuous as trying to transform a wolf into a watchdog by a chemical process or surgical operation. But while the radical "reformer"—the man who would ignore the lessons of history and launch boldly out upon the tempestuous sea of experimentalism—is one dangerous extreme, we must remember that it is not the ...

... by the chemical process of his malady, after he had created jealousy out of his love, he began again to generate tenderness, pity for Odette. She had become once more the old Odette, charming and kind. He was full of remorse for having treated ...

... effect of her words. I could not now use the precaution in her case, which it had somehow seemed natural to adopt with Eive, of marking the paper returned for erasure. On her part, Eunane thrust into my hand the whole bundle as they were, and I was forced myself to erase, by an electro-chemical process which leaves no trace of writing, the words of that selected. The absence of any mark on the second paper served sufficiently to distinguish the two when, of course without stating from whom I received them, I ...

... the legs that carry it to you. Carbon is the same thing, whether you call it wood, or coal, or bread and cheese. A reverend gentleman demurred to this statement,—as if, because combustion is asserted to be the sine qua non of thought, therefore thought is alleged to be a purely chemical process. Facts of chemistry are one thing, I told him, and facts of consciousness another. It can be proved to him, by a very simple analysis of some of his spare elements, that every Sunday, when he does his duty faithfully, he uses up more phosphorus out of his brain ...

... years' research there has been produced a miniature electric bulb that is a great improvement and a decided departure from the old kind which used a carbon filament. A metallic filament prepared by a secret chemical process and suspended in the bulb in an S-shape is used instead of the old straight span. The voltage is gauged by the length of the span. The brilliancy of the filament excels anything of its ...

... ain't it? Why, say, the first thing I knew I'd picked out old D. K. Rutgers, the worst fish-face in the bunch, and was throwin' the facts into him like I was shovelin' coal into a cellar chute. Beginnin' with Rowley's plan for condensin' commercial acids from the blast fumes, explainin' the chemical process that produced 'em, and how they could be caught on the fly and canned in carboys for the trade, I galloped through the whole proposition, backin' up every item with figures and formulas; until I showed 'em how the slag ...

... claim to make all their plates without any retouching, which cannot be done. As I have mentioned before, occasionally a plate can be made as good as the copy without hand-work. But to say that any chemical process gives such results continually, or that a plate cannot be improved by a skilful retoucher is, to say the least, misleading. All of the different processes are very sensitive to atmospheric influences, and no small amount of chemical as well as mechanical skill is required to keep things running ...

... Concrete.—The setting action of cement is a chemical process, not merely a drying out of the water introduced in mixing the concrete. The chemical action is progressive for a long time, but is more rapid during the first few hours than during the later periods, and the concrete reaches about three-fourths of ...

... pointed out to me by M. Gazzeri, the Professor of Chemistry at Florence. A few years ago an important suit in one of the legal courts of Tuscany depended on ascertaining whether a certain word had been erased by some chemical process from a deed then before the court. The party who insisted that an erasure had been made, availed themselves of the knowledge of M. Gazzeri, who, concluding that those who committed the fraud would be satisfied by the disappearance ...

Exposed to the sun in a window or on the snow, it will become perfectly white, when it can be made into cakes for market, where it commands a much higher price than the yellow. It is said there is a chemical process that whitens it readily, but I am not ...

... required to sign his examination he refused. He said it was unnecessary; that, knowing all the secret machinery of the police, he suspected that by some chemical process they would erase all the writing except the signature, and afterwards fill up the paper with statements which he had never made. His refusal to sign the interrogatory, he added, would not prevent him from repeating before a court of justice the truth which he had stated ...

... of immense benefit to his own and succeeding generations. By him was discovered the art of extracting tar from coal, and out of that discovery was developed, partly by him and partly by others, the manufacture of gas, first used for lighting his tar-works. The important chemical process of making alkali and crystals of soda was also introduced by him, whereby a great impetus was given to the manufacture of glass and to many other important branches of industry. He discovered the present method of ...

... organism which transforms various forms of force into thought-force, an organism the activity of which we maintain by what we call 'food,' and with which we produce what we call 'thought.' What a marvellous chemical process it is which could change a certain quantity of food into the divine tragedy of Hamlet." This is quoted from a pamphlet of Robert G. Ingersoll, bearing the title, Modern Twilight of the Gods. It matters little if such thoughts find but scanty acceptance in ...

... disbelieve. Frankly, I do not know. What people call God, Jehovah, Nature, according to my reasoning, is an astounding energy, a marvellous chemical process, created and controlled by some unknown, stupendous first cause, the origin of which man may never understand. How should he? He has not time. We are rushed into the world without preparation. We are ignorant, helpless, blind. Gradually, by dint of much physical labor and ...

... acted proportionally stronger, and have consequently left the urine in a less dilute state. In this urine the transparent sediment or cloud is mucous; the opake sediment is probably coagulable lymph from the blood changed by an animal or chemical process. The floating scum is oil. The angular concretions to the sides of the pot, formed as the urine cools, is microcosmic salt. Does the adhesive blue matter on the sides of the glass, or the blue circle on it at the edge of the upper surface of the ...

... stress upon the emotions. He goes so far as to say that they "undoubtedly occupy the first place amongst the factors causing disease, and we must not evade the consideration of them. We shall find that their action also amounts to an electro-chemical process." I would not for an instant be understood to contend that the emotions alone are sufficient to explain the origin of disease—not at all. There are other factors—jointly or severally dominant—diet, occupation, changes ...
