"Propulsion" Quotes from Famous Books



... and distance of most of our ports from the markets supplied by European manufactures, for a long time to come make the home-supply the chief care of our artisans. They have, for such and other reasons, in some points lost ground of late. The revolution in the propulsion and construction of ships, for instance, has not found them prepared to take the advantage they have usually done of improvements. Not only do the British screw-steamers take undisputed possession of our trade with their own country, but ...

... world is indebted to Robert Fulton for the practical application of steam to the purposes of navigation. Whatever has been claimed for or by others in regard to the priority of the invention or application of the mighty power of steam to the propulsion of vessels, Fulton was "the first to apply it with any degree of practical success," as an English work states it. As one who labored for years over the idea which came from his own brain, though it also came to others, who wellnigh sacrificed his own life in its improvement, and who achieved ...

... second-class, 5 tons 10 cwts., each with passengers; a Pullman car weighs about 30 tons. Our steamers consume 5 lbs. of coal per horse-power in one hour. And last, not least, one of the greatest improvements we have had in steam propulsion is the screw. Again, I may also name the great advantage derived from steam by our farmers in thrashing out grain. The engines principally used in farm-work are what are termed high-pressure, or of the same class ...

... is to move, or control the movement of, materials within cavities and tubes, and they do this by means of the pressure which they exert. Examples of their action have already been studied in the propulsion of the food through the alimentary canal and in the regulation of the flow of blood through the arteries (pages 159 and 49). While they do not contract so quickly, nor with such great force as ...

Her whole bow formed a powerful ram; the shield, flat on the top, was pierced for ten guns of heavy calibre, three in each broadside, two forward, and two aft. Had her means of propulsion proved equal to her power of attack and defence, it is doubtful if the whole Union navy on the Mississippi could have stood against her single-handed. The situation thus strangely recalls that presented by the Merrimac, or Virginia, in ...

... water, which is a non-exhaustive source of motion, was used, the people were scattered over the land; or if segregation took place, it was in the neighborhood of running streams. The application of steam to the propulsion of machinery, and the discovery of engines capable of competing with the human hand, led to the substitution of machine-made fabrics for clothing, in place of homespun articles of domestic manufacture. This led to the employment of farm-laborers ...

I watched with great keenness the motion of their arms that gives the propulsion to their spears, and the instant I observed that, I ordered a discharge of the two rifles and one gun, as it was no use waiting to be speared first. I delayed almost a second too long, for at the instant I gave the word several spears ...

... this money, although knowing well enough it was not mine to take, was too great for me. It was the resultant of every force of, I might say, my special business propulsion. This temptation lay along the lines on which I had built up my life: the pursuance of a line of action by which I might get rich quick.—Then came the crash. That special guaranteed stock broke—never to rally in time to save me—sixty-five points. ...

... application was filed, the automobile was practically unknown to the general public, but by the time the patent was issued everybody was familiar with self-propelled vehicles, and most of the men, including myself, who had been for years working on motor propulsion, were surprised to learn that what we had made practicable was covered by an application of years before, although the applicant had kept his idea merely as an idea. He had done nothing to put ...

... this city Dec. 6, 1867, at the age of 67. A long and eminently useful although unobtrusive life entitles his memory to respect. He commenced his career as a mechanic in the steam engine establishment of James P. Allaire, soon after the application of steam for the propulsion of boats and long before its application to ships for the purposes of commerce or war. For fifty-two years, with the exception of one or two brief intervals, he was connected with the Allaire works in this city, and for more than forty years ...

... type of machine. I'm going to call it the Damon Whizzer. Maybe Demon Whizzer would be more appropriate, but we won't decide on that now. Anyhow, it's going to be a whizzer, and I want to talk to you about it. There is an entirely new principle of elevation and propulsion involved in my Whizzer, ...

... vertical shaft or stake, provided with a couple of old cart-wheels, in a hole in the ice. One wheel acts as a turning base and prevents the shaft from sinking into the pond, and the other forms a support for the long sweep attached for propulsion purposes, and should be fastened to the shaft about 3 ft. above the base wheel. The sleds are made fast in a string to the long end of the sweep, which when turned rapidly causes the sleds to slide over the ice in a circle at ...

... distinguished what was clearly a mast with a sail, though, as there was very little wind that morning, the sail hung idly by the mast. A little later we were able to be sure that what we saw was a kind of raft, with, as I have said, a mast and sail, but that its propulsion came from some human beings who were aboard it, and who were causing its slow progress with oars. By this time I had got out a spy-glass from our tent; and then Lancelot gave a cry of amazement, for he recognised in the new-comers certain of those colonists our companions whom we had left behind ...

... passions through the imagination, while insensibly helping them toward balance of character and serenity of judgment by stimulating their sense of proportion, form, and the nice adjustment of means to ends. In none of our poets has the constant propulsion of an unbending will, and the concentration of exclusive, if I must not say somewhat narrow, sympathies done so much to make the original endowment of nature effective, and in none accordingly does the biography throw so much ...

... years or so that they took the matter up, after a successful voyage made by the Archimedes, the first sea-going screw steamer. They then built a small craft called the Bee, fitted with both paddles and screw, to try which was the better means of propulsion. The screw had the best of it, and after the further experiment of building two vessels of the same size and power, the one with paddles the other with a screw, and finding the screw still superior, ...
