Seite 132 - As the steam vessel moves round, it is supplied with steam from the boiler, and that which has performed its office may either be discharged by means of condensers, or into the open air. Sixthly, I intend, in some cases, to apply a degree of cold not capable of reducing the steam to water, but of contracting it considerably, so that the engines shall be worked by the alternate expansion and contraction of the steam. Lastly, instead of using water to render the piston or other parts...
Seite 140 - In the formation of the railway there have been dug out of the different excavations, upwards of three millions of cubic yards of stone, clay, and soil, and the weight of the double lines of rail laid down is more than 4,000 tons. The total expenditure of the Com-pany, in actual payments, up to the 31st of May last, was 739,165Z.
Seite 75 - Now Know Ye, that in compliance with the said proviso, I, the said Adolphe Nicole, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed...
Seite 48 - The advantages contemplated are stated by Mr. Dick as follows : — " In the first place, as you save distance, so do you save time ; which, all must admit that, in a commercial as well as in a political point of view, is of the utmost importance. The suspension rail takes a straight forward point from one town to another, without regard to the surface of country over which it has to go, whether rising or falling, crossing of rivers, or otherwise.
Seite 137 - Hill, a distance of rather more than a mile and a quarter. It was constructed in seven or eight separate lengths, each communicating with the surface by means of perpendicular shafts. The...
Seite 101 - Ou one side of this ring a notch is made, to admit two communications, the one for the ingress- and the other for the egress of the steam or other fluid by which the machine is to be put in motion. Now, suppose the ring to be raised on the side next to the passages, the steam water or other actuating fluid can enter, but cannot pass round to the egress passages, without raising the ring on the opposite side ; and it cannot, from its...
Seite 209 - ... interposed. He likewise concluded, that friction increased or diminished with the velocity, and varied in the ratio of the weight and pressure of the rubbing parts, and the times and velocities of their motions. These hypotheses were adopted more or less by most of the philosophers after Amontons, but particularly by De la Hire,!
Seite 254 - And further, where the common sliderest is only applicable to the formation of flat surfaces, the improved one is equally applicable to their formation in the form of lenses, either convex or concave. The principle on which the improvement is constructed depends upon two geometrical propositions — first, that all angles in the same segment of a circle are equal ; and, second, that if a straight line be made to move always parallel to itself with one end touching a circle, the other end will describe...
Seite 145 - ... any part of it, so that the plate will stand horizontally. At a little distance from the periphery of this plate, an iron spindle crosses the frame ; upon this spindle are lifters, which, as it is turned by a crank, come in contact with the lower side of the plate, and raise the shaft ; friction rollers are contained within the lifters, to cause them to slide easily upon the plate, and their action is so managed as to produce a small revolution of the plate, and consequently of the drill, at...
Seite 138 - A little to the south of the town of Newton the railway crosses a narrow valley, by the short but lofty embankment of Sandy Mains, and a handsome bridge of four arches, each 40 feet span, under one of which passes the Newton and Warrington turnpike road.
