    Newtons Improvements in the Manufacture of Coke, cfyc. from whence the solution will pass into the concentrating apparatus. H is a centrifugal or other ventilator for increasing the draft. It has not been deemed necessary to give a detailed Drawing of this part of the apparatus, as its con¬ struction is well known. Any other kind of exhausting apparatus may, however, if desired, be employed instead of the ventilator or fan H; for instance, jets of 5 steam suddenly condensed in a chamber connected with the vessel E will have the effect of creating partial vacuum therein, and will draw the gaseous products through the apparatus. The ventilator will draw off the uncombined gases from the upper part of the vessel E through the pipe e2, and force them through the pipe I, by which they will be conveyed away, and as they will be 10 found to consist for the most part of combustible gases, such as carburetted or sulphuretted hydrogen, they may be conducted under the concentrating boiler or evaporating vessels, and employed as fuel for heating and concentrating the liquid salts of ammonia which have been produced in the vessel E. The pipe e~ is continued a little lower than the entrance of the ventilator in 15 order to allow the condensable matters which may be disengaged to be collected in this prolonged part, which is furnished with a discharge cock, as seen best in Fig. 3. Figures 7, 8, and 9 (Sheet II.), represent detached views of the refrige¬ rator, drawn to a scale of one tenth the real size. It will be understood that 20 unless the temperature of the gas is reduced, large quantities of carbonaceous matter in the form of smoke would pass into the apparatus, but by reducing the temperature of the gases, the smoke will be condensed and made to deposit in the form of soot in the refrigerator, from whence it may be removed through the openings c, c; but if the gaseous products highly charged with 25 carbonaceous matter as given off from the ovens were allowed to pass through the pipes of the refrigerator, the pipes would quickly become clogged with soot and thereby greatly obstruct the working of the apparatus ; it is therefore indispensable to cause the refrigerating water to pass through the pipes instead of the gases, which become cooled by coming in contact with the 30 cold surfaces of the pipes. The refrigerator is composed of a series of flanged pipes of cast iron, which must not exceed three eighths of an inch in thickness, set one above the other in the chamber C (Sheet I.) There are only two kinds of pipes, the curved ones ds, furnished with circular flanges, and straight ones d\ furnished with rectangular flanges, which by being bolted together 35 form partitions, dividing the chamber C into three parts, d, d\ dK The gases pass from the flue or chimney B down into the part d, where they are cooled by passing between the curved pipes, and deposit the lamp black or soot at the bottom, passing thence through the opening c7 into the part d2, from whence,
