Not illustrated. 1891 Excerpt: ...automatic apparatus can be made by putting on to the horizontal part of the exit-pipe a perpendicular 12-inch pipe, closed by a bell standing in an annular water lute. The bell hangs on one arm of a lever, whose other arm is so weighted that the bell can travel freely. When the draught is just right, this second arm has a certain position, in which a throttlevalve within the exit-pipe connected with it is half open. When the draught increases, the bell descends, owing to the increase of atmospheric pressure, and partly shuts the throttle-valve; in the opposite case of the draught decreasing, the throttle-valve is opened wider. This apparatus, as constructed by M. Delplace, and employed by him for the last ten years with the greatest advantage, is shown in fig. 171, where a is the entrance-pipe from the GayLussac tower, c the exit-pipe, b a conical valve, d the regulating bell, e e the water-line of the hydraulic joint, / the lever, g the balance-weight. Somewhat different in detail, and apparently very accurately working, is the apparatus of Mr. W. G. Strype, of Wicklow, of which the following is a description (patent No. 705, Feb. 21st, 1879): --The accompanying drawings illustrate two forms of the apparatus, fig. 172 being the most desirable, although somewhat more expensive in construction than the arrangement shown in fig. 173. Referring to fig. 172, an inverted vessel or receiver A, open at its lower end, dips into a tank A', containing water or other suitable liquid acting as a hydraulic joint. The interior of A is placed in communication, by means of the pipe or passage ab c, with a receptacle R connected with the main flue from the absorbingtowers and chambers. This receptacle is also in communication with a flue leading to the chimney, or other devi..</p>

The Manufacture of Sulphuric Acid and Alkali, Vol. 1: With Collateral Branches (Classic Reprint)

Excerpt from The Manufacture of Sulphuric Acid and Alkali, Vol. 1: With Collateral BranchesThe fourth edition of my treatise on the Manufacture of Sulphuric and Nitric Acid, etc., was published in February 1913, and has met with general approval on the part of the numerous class of persons interested in that important domain of technical chemistry. Since the issue of the fourth edition very numerous contributions have been made to the industries described therein, by patent specifications and by publications in the professional literature of all industrial countries. I have also obtained various communications from private sources on the subjects treated in this book. Very naturally most of its readers are desirous of becoming acquainted with this new matter, and the publishers have informed me of the great number of inquiries addressed to them thereon. The general wish seems to be for a Supplement giving an account of the new matter, without compelling the purchasers of the last edition to buy an entirely new edition, and the present volume is intended to meet that desire.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
