This misty acid is composed of sulphur dioxide, nitrous oxide and water as vapor or steam. Lunges theory is now the accepted authority on chamher reaction. It is as follows, viz. : Sulphur dioxide combines directly with nitrogen trioxide, oxygen and a little water to form nitrososulphuric acid, which floats in the chamber as a mist; in meeting an excess of water equally floating about as a mist (probably mostly or all in the shape of very dilute sulphuric acid) the nitrososulphuric acid splits up into sulphuric acid, which sinks to the bottom, and nitrogen trioxide, which begins to act anew. Hence, it is not, as hitherto generally assumed, the nitric oxide, N 0, but the nitrogen trioxide, NO, which acts as the oxygen carrier in the chamber process. The misty acid as formed is very slowly deposited in drops, which form larger drops, or liquid, when it strikes the walls of the chambers or the bottom acid, and does not so deposit itself unless it does strike these surfaces or others. The conversion of the S 0 into HS () takes place very quickly as far as the middle of the first chamber, where considerably over 50 of the total acid is produced. After that it slackens very much, but suddenly revives when the gases pass into the second chamber. The sulphur dioxide, S 0, is produced by burning sulphur or sulphide ores, such as iron pyrites, in furnaces with an excess of air, and passing the gases through various apparatus to the chambers. The nitrous oxide, NO, is generally obtained by the potting method in fertilizer acid plants, i. e. , decomposing nitrate of soda into nitrous acid gas and. . .

Natural cork contains a resin, which can be drawn out by application of about 509 degrees Fahr. of heat, at which temperature the cork will char. Briefly the process is: Ground cork fed by a blower system enters overhead bins and is finally lodged in a hopper, after being passed through a steaming box. It is then allowed to fall by gravity into steam heated hydraulic pressing molds (consisting of iron frame with portable tops and bottoms) which compress the cork into a solid mass as the molds have a very high temperature. From the molds the cork is conveyed by iron tracks or iron roller gravity carriers which pass through long brick baking ovens (heated by coal, producer gas or coke) well set and of substantial brick construction. The ovens are similar to the leer in a glass works. After baking for several hours the Rotary Cork Cutter Or Grinder. This machine has from twelve to sixteen blades or knives, part of which are stationary and part revolving. They reduce the cork to uniform fineness. cork passes out of ovens and is then removed from the molds, planed and sawed, and is then ready for shipment. CORK pISC BOTTLE STOPPERS. The cork is received in a ground state; it is then mixed in an agitator with a hot mixture of glycerine and a vegetable gum (similar to gum arable), then put in a steam heated kettle and mixed with paraffine, pressed by hydraulic machines into blocks baked in gas heated ovens, and then cut into thin sheets by power saws, and the discs finally punched out by special machines.
