. Machinery and processes of the industrial arts, and apparatus of the exact sciences. a succession oflittle conical shaped receivers with-in the condenser, which form a rowof collars round the cylindrical inner wall, so arranged as to fill Carrfe,8 Ammoniacai FYeez[ng Apparatus forsuccessively with the condensed families liquid, and thus to present a larger evaporating surface when the refrig-erating process begins. The boiler and the refrigerator are connected by a tube which receivesthe liberated gas at the top of a cylindrical dome surmounting the appendage is designed to allow opportunity for the steam whichrises along with the gas to become condensed, and to return again to theboiler in the form of water, which in great measure it does. The con-necting tube enters the refrigerator near the top also. To give steadi-ness and strength to the apparatus an intermediate brace is introducedbetween the boiler and the lower part of the connecting tube; and thisserves conveniently as a handle. After what has been said, the mode of employing the apparatus hardly. 372 PARIS UNIVERSAL EXPOSITION. requires description. There are necessary a suitable portable furnace,and a large tank to serve as a condensing refrigerator. This tank is tobe filled from any natural source with water at the ordinary tempera-ture. The boiler charged with the solution is placed over the furnace,and the apparatus is first purged—that is to say, cleared of is done after the temperature of the boiler has been somewhatraised, by turning a stop-cock (not shown in the figure) which allowsthe air to pass off as the gas set free by the heat fills successivelythe different parts of the apparatus. The expelled air is conductedby a tube into a vessel called the purger, where it is dischargedbeneath the surface of water. Any ammonia which may pass overwith it is dissolved by the water and saved. When the purging iscomplete, the stop-cock is closed, and the temperature is steadily raise
