Page 32 - The principle involved in more elaborate forms of plant employed on a large scale is exemplified by the wellknown Soxhlet extractor. The extraction here takes place continuously with a limited amount of solvent charged once for all into the apparatus. When the seed is deemed completely...
Page 43 - Oils are heavy, viscid liquids obtained by treating castor (or linseed) oil with a mixture of 2 parts of concentrated sulphuric acid and I part of concentrated nitric acid (sp.
Page 330 - The pans are usually provided with a set of stirrers to prevent the acetate from burning to the bottom. The tarry matter rising to the surface is removed through a sliding door. When the specific gravity (measured hot) reaches 1.116 the separation of acetate begins and gradually the mass forms a thick paste which is removed and spread on flat iron pans to be dried. Some finish the drying in rooms heated by the waste furnace or retort gases. The residue in the stills is " boiled tar," and is removed...
Page 625 - Client., 1907, 262) gives an example from practice in which equal parts of nitric acid of 75 per cent, monohydrate and sulphuric acid of 96 per cent, monohydrate (also a mixed acid with 14.5 per cent, water) are used in 25 parts of which I part of cotton is nitrated for iI } hours at 40° C.

The jet of oxygen is made sufficiently strong to blow away this iron oxide in front of it, with the result that a clean narrow cut is effected through the metal at a speed of travel which is comparable with hot sawing. The metal on each side of the cut is neither melted nor injured in any way, as the action proceeds too rapidly for the heat to spread ; in fact the edges present the sharp and purely metallic surface of a saw cut. The cutting may be made to follow any desired line, executing...
