• The cost of an acetylene generator is about $50 for a small house, and the cost of maintenance is not more than that of lamps. 伯莎M.克拉克. 科学通论.
• The simplicity of the method of generating acetylene gas from this substance by merely bringing it in contact with water has greatly stimulated invention in this field. Edward W. Byrn. 十九世纪发明进展.
• Acetylene is seldom used in large cities, but it is very widely used in small communities and is particularly convenient in more or less remote summer residences. 伯莎M.克拉克. 科学通论.
• When the hard, gray crystals of calcium carbide are put in water, they give off acetylene, a colorless gas which burns with a brilliant white flame. 伯莎M.克拉克. 科学通论.
• Acetylene gas finds its principal uses for isolated plants, and in country houses. Edward W. Byrn. 十九世纪发明进展.
• The art began practically in 1895, and since that time more than 500 patents have been granted for acetylene gas apparatus. Edward W. Byrn. 十九世纪发明进展.
• Acetylene Gas from Calcium Carbide by Willson. Edward W. Byrn. 十九世纪发明进展.
• It was discovered in 1836 by Edmond Davy, who produced carburet of potassium, and evolved acetylene gas therefrom by decomposing it with water. Edward W. Byrn. 十九世纪发明进展.
• In acetylene gas apparatus a great variety of methods are employed for bringing the water and carbide into contact. Edward W. Byrn. 十九世纪发明进展.
• It is now made commercially by the mutual decomposition of water and calcium carbide, the latter giving off, when brought in contact with the water, acetylene gas, which rises in bubbles. Edward W. Byrn. 十九世纪发明进展.
• Acetylene gas is immediately generated and its pressure forces the level of the water down in the inner cylinder, causing it to rise in the annular space between said cylinder and the case. Edward W. Byrn. 十九世纪发明进展.
• Great attention has recently been paid to the production of _acetylene_ gas, produced by the reaction between _calcium carbide_ and water. 威廉·亨利·杜利特. 世纪发明.
