"Condensing Apparatus for Steamer's Side Lights.—By means of this application of the condensing principle all the light can be distributed with strict equality over 112 degrees, which is the arc prescribed for steamers by the Board of Trade. Several of the Transatlantic and other steamers have adopted this kind of apparatus, which is hung on gimbals and placed in iron towers, having an entry from below the deck, which can be made use of in bad weather." —The Encyclopedia Britannica, 1910

"Condensing Octant.—The central fixed apparatus bb with spherical mirror dd throws its rays directly over the angle of 45 degrees pgp, while the supplemental rays fall upon the straight condensing prisms p, each of which spreads the incident rays parallel to the corresponding rays in the central angle pgp. In this way the whole of the front hemisphere of rays is parallelized in the vertical plane and spread equally over the 45 degree in azimuth." —The Encyclopedia Britannica, 1910

"The condensing pump is an instrument for compressing a gas into a closed vessel, as in pumping air into a pneumatic tire of a bicycle, or oxygen or hydrogen into the cylinders commonly used for stereopticon purposes, or charging water with carbon dioxide for sale as 'soda water'." -Avery 1895

"Condensing Quadrant.—The fixed apparatus bbb, with spherical mirror behind, throws its rays directly through the angle of 90 degrees afa', while the supplementary rays falling on the straight condensing prisms p, p, p', p' are sent out parallel to the corresponding rays in the unobstructed central quadrant of the main apparatus. The whole light will therefore be condensed equally over 90 degrees." —The Encyclopedia Britannica, 1910

"Wood is heated in cylindrical iron retorts. the volatile materials are cooled, and while a portion remains gaseous and is used as fuel, a large part is condensed to a dark, tarry liquid." -Brownlee 1907

"Impure water is vaporized in the boiler, A. It travels to the vat and down pipe R where it condenses and distilled water finally collects at the bottom. Cold water enters the vat at P and warm water at the top escapes at Q." —Quackenbos 1859

"The sulphur is then further purified by heating it in iron vessels (retorts) without access of air, until it is vaporized. the vapor is led into brick-lined rooms. A part of the gas is suddenly cooled and is deposited as a fine powder on the sides of the room. The form is known as flowers of sulphur. Most of the sulphur vapor condenses in the liquid form, and flows down to the outlet of the condensing chamber." -Brownlee 1907
