Stran 480 - When the electrodes are in contact, the current circulating through m renders it magnetic and attracts the armature a, thus separating the electrodes, when, on the weakening of the current, the elasticity of the rod b again restores the contact During the movement of the negative electrode, since it is caused to occur many times...
Stran 279 - ... timber may be safe against injury under the heaviest load which occurs in practice, and to form and fit every pair of such surfaces accurately, in order to distribute the stress uniformly.
Stran 268 - ... culvert. If the water of the brook is generally limpid, and its current gentle, it may, in the last case, be received into the canal. The communication of the brook, or feeder, with the canal, should be so arranged that the water may be shut off, or let in at pleasure, in any quantity desired. For this purpose a cut is made through the side of the canal, and the sides and bottom of the cut are faced with masonry laid in hydraulic mortar.
Stran 260 - The resist style, where the white cloth is impressed with figures in resist paste, and is afterward subjected first to a cold dye, as the indigo vat, and then to a hot dye-bath, with the effect of producing white or colored spots upon blue ground.
Stran 469 - Light, Heat, Electricity, Magnetism, Motion, and Chemicalaffinity, are all convertible material affections ; assuming either as the cause, one of the others will be the effect : thus heat may be said to produce electricity, electricity to produce heat; magnetism to produce electricity, electricity magnetism ; and so of the rest.
Stran 59 - Zinc may be added to pot metal in very small quantity, but when the zinc becomes a considerable amount, the copper takes up the zinc, forming a kind of brass, and leaves the lead at liberty, and which in great measure separates in cooling. Zinc and lead are also very indisposed to mix alone...
Stran 326 - The inclination of the grate in this machine is from five to eight degrees. It is fed through the hopper B, which plunges below the surface of the stuff accumulated on the grate. The loss of water which occurs at each stroke of the piston is replaced from a reservoir W, at the back of the apparatus. According to...
Stran 283 - Notes on Building Construction. Arranged to meet the requirements of the Syllabus of the Science and Art Department of the Committee of Council on Education, South Kensington.
Stran 443 - Newton generalized the law of attraction into a statement that every particle of matter in the universe attracts every other particle with a force which varies directly as the product of their masses and inversely as the square of the distance between them; and he thence deduced the law of attraction for spherical shells of constant density.
Stran 479 - ... recede a distance apart, which can be regulated. These motions or vibrations are made to follow one another at such a rate that the effect of the light produced is continuous ; for, as is well known, when flashes of light follow one another at a rate greater than 25 to 30 per second, the effect produced is that of a continuous light. The...
