"The large driving cone J is hollow, the smaller or driven one convex. The latter presses, when desired, against the ineer surface of the former; its speed depends upon its position with regard to the axis of the driver. When its axis is in line with that of the driver, it has the same speed; the further it is drawn laterally therefrom, the greater the speed." —Grimshaw, 1902

"Infernal machine designed by the Confederates to destroy the Federal Flotilla in the Potomac discovered by Captain budd of the steamer "Resolute." An infernal machine designed by the Confederates to blow up the "Pawnee" and the vessels of the Potomac flotilla, which was set adrift near Aquia Creek, was picked up on the 7th of July, 1861, floating toward the "Pawnee." The following description of the article was sent to the Navy Department: "Two large eighty-gallon oil casks, perfectly watertight, acting as buoys, connected by twenty-five fathoms of three-and-a-half-inch-rope, buoyed with large squares of cork, every two feet secured to casks by iron handles. A heavy bomb of boiler iron, fitted with a brass tap and filled with powder, was suspended to the casks six feet under water. On top of the cask was a wooden box, with fuse in a gutta-percha tube. In the centre of the cork was a platform with a great length of fuse coiled away, occupying the middle of the cask." — Frank Leslie, 1896

"After thorough drying, the air to be liquefied enters through the pipe a, and in the compresor C is compressed to about 200 atmospheres. R is a water cooler, to remove the heat of compression. The air thus cooled and strongly compressed passes down through the inner tube of the helical coil H to a valve below." —Derr, 1911

Wave motors were machines designed and built in the late 19th and early 20th century to harness the power of wave or tidal energy. The earliest wave motors were not intended for the creation of electricity. Prior to 1880, wave motors were designed to operate non electrically to power vehicles, mills, flush sewers, clean streets and conserve fresh water

An illustration showing the application of a jet condenser to pump a well. The steam enters the engine and leaves as exhaust. The exhaust steam is cooled by the well water in the jet condenser, then gets pumped into a separator. One stream exits into the sewer, and the remainder is pumped to the boiler as liquid and recycled into the condenser as steam.

"Smelting is the act or process of obtaining metal from ore by the combined action of heat, air, and fluxes. In smelting iron the ore is first roasted in a kiln in order to drive off the water, sulphur, and arsenic with which it is more or less combined in its native state, and is then subjected to the heat of a blast furnace along with certain proportions of coke or coal and limestone, varying according to the composition of the ore to be heated."—(Charles Leonard-Stuart, 1911)
