India=Rubber and Gutta-Percha and Electrical Trades Journal Vol. XIV., No. 7. September 17, 1897. PRICE SIXPENCE PRACTICAL REVIEW OF SOLVENTS AS USED IN THE INDIA-RUBBER AND GUTTA-PERCHA INDUSTRIES. EFFECTUAL UTILISATION AND PREPARATION OF THE VARIOUS SOLVENTS. THEIR VARIED NATURE AND PATENTS INTRODUCED. BY A. CAMILLE. {^Continued from page 131.) APPARATUS APPFIRTAINING TO THE DISSOLUTION OF ELASTIC GUMS.— USEFUL PATENTS INTRODUCED. A HIGH STANDARD KNEADING AND MIXING MACHINE. IT must be acknowledged as a coiiccdL'd fact that tlie improved modes of construction of these machines hy Messrs. Werner, Pfieiderer and Perkins, Limited, have reiched a very high standard, both from a technical and business point of view. Where the principal aim of the manufacturer is improvement whereby whole industriesare benefitted, and where hy the result he can exalt industrial functions, he should in like measure be rewarded in honour and material emoluments; for the inevitable outcome of such lofty endeavours will be that .not only are we supplied with needs of an improved degree or standard, hut will secure truer foundations of commercial prosperity as their natural consequence. These typesof masticators,asmanufactnredhytheabove firm and which are known as the Universal Kneading and Mixing Machines, can be adapted for almost all descripti'ns of substances where kneading, mixing, incorporating, masticating, scarifying, malaxating, pugging and massing has to be resorted to. The constructions as seen in Figures i and % are especially suited where kneading and mixing has to be carried out at artificial and varying temperatures, or in other words, where the materials are to be manipulated at will at temperatures either higher or lower than that of the ordinary surrounding atmosphere. Both these types of machines [^are made to order in any requisite dimensions, and they are so constructed that both high pressure steam as well as cold water may be laid on and circulated at will through the casing of the trough or container, as also through the blades. The steam may be of a pressure as high as 6o or 70 lbs. to the square inch, viz., upwards of four atmospheres, while if required the water may be artificially cooled (iced), and by this ingenious provision a considerable grading oj temperature can he ensured. This, coupled with the intense and intimate mixing qualities of these types oJ machines enable the mamifacturers to obtain results—on a large scale and of desired differentiation—hitherto unattained outside the experimental laboratory. The type as seen in Fig. i is chiefly used for india-rubber, gutta-percha, lincrusta, linoleum, etc., although occasionally it is also employed for other purposes such as the manufacture of explosives, etc. The type repiesented in Fig. 2 is fully equipped and fitted for heating by steam under pressure or cooling by water, both body and blades, .is alluded to in the above, while the machine is working or standing still or tilting, two connections only having to be made, one with the steam inlet and the o'her with the outlet pipe. There is also a steam trap for separating the condensed water. All the above machines for power are fitted with the firm's own patent reversing gear for convenient driving (hy belts) in opposite directions and for stopping the machine. With this gear the operative has the stopping.

A HIGH STANDARD KNEADING AND MIXING MACHINE. IT must be acknowledged as a coiiccdL'd fact that tlie improved modes of construction of these machines hy Messrs.

Where the principal aim of the manufacturer is improvement whereby whole industriesare benefitted, and where hy the result he can exalt industrial functions, he should in like measure be rewarded in honour and material emoluments; for the inevitable outcome of such lofty endeavours will be that .not only are we supplied with needs of an improved degree or standard, hut will secure truer foundations of commercial prosperity as their natural consequence. These typesof masticators,asmanufactnredhytheabove firm and which are known as the Universal Kneading and Mixing Machines, can be adapted for almost all descripti'ns of substances where kneading, mixing, incorporating, masticating, scarifying, malaxating, pugging and massing has to be resorted to.
