"The Danglish apparatus consists of the following parts: 1st, a generator A, in which carbonic acid is evolved from chalk by sulphuric or hydrochloric acid; 2nd, a gas-holder, in which the carbonic acid is stored for use after being purified in passing through water; 3rd, an air pump, for pumping carbonic acid from the gas-holder, and forcing it into the water vessel and mixer; 4th, another air-pump, for withdrawing atmospheric air from the mixer before the aerated water is admitted; 5th, a water vessel B, a strong cylinder of copper capable of withstanding a pressure of 100 lbs on the square inch, and of sufficient size to contain water for a full charge of the mixer; attached to this water vessel there are a gauge-glass C, and a pressure gauge D, for indicating the pressure of gas as it is pumped in; 6th, the mixer E, a globular vessel of cast-iron, capable of bearing high pressure, through the center of which an axle runs, fitted with iron kneating arms extending to the circumference of the vessel." — Encyclopedia Britanica, 1893

"By placing the condensers underneath the turbine, as is frequently done at the present time, not only may a considerable amount of floor space be saved, but the turbine can more readily exhaust into the condenser. As we have already seen, at high vacuum the volume of steam is very large, and the exhaust pipe from the turbine will be proportionally large." —Derr, 1911

"The bearings are of the plain ring—oiling type, usually provided with water jackets. The shaft not being unduly long, there is little danger of whipping, and the speeds of rotation not being very high, special precautions are not necessary. Sometimes the turbines are supported by three bearings, the high and intermediate states being separated from the low by a third bearing." —Derr, 1911

"Turbines require very much smaller foundations than reciprocating engines reciprocating engines of the same power, and these foundations will therefore cost very much less. It is hard to get a direct comparison between turbines and reciprocating engines as a class, because the foundations for high—speed reciprocating engines will not be as massive as for the heavier, low—speed engines." —Derr, 1911

"The Zoelly turbine has been developed rather extensively abroad, and is being manufactured largely through a syndicate of builders including some American firms. It is a turbine essentially of the Rateau type, a multi—pressure—stage turbine, but it has fewer stages, usually not over ten for condensing and five for non—condensing." —Derr, 1911

"The shaft, where it passes through the diaphragm, is fitted to a bronze bushing with a few thousandths of an inch clearance. This bushing seats on the metal surface of the diaphragm with latitude for slight side motion. It is kept to its seat by the steam pressure, but can move sideways to accommodate any whipping motion of the shaft." —Derr, 1911
