Title: Improvements in Brick and Tile Kilns Combined with Artificial Drying Chambers.
Inventor: BUEHRER JACOB
Filed: 1898-04-30
Granted: 1899-04-29
Abstract: 9935. B³hrer, J. April 30. Kilns.-Relates to brick and tile kilns combined with drying-chambers, and more particularly to a system of flues and channels whereby all the available heat of the cooling portion of the kiln is conveyed to the drying-chambers and thoroughly distributed therein. Fig. 1 shows a sectional plan of the kiln and a portion of the drying-apparatus, the central part being taken on a plane above the roofs of the kiln chambers, and Fig. 2 shows a longitudinal section in elevation of the drying- apparatus and part of the kiln. The kiln is divided into a series of chambers a<1> ... a<6> by hollow division walls b, d, forming hot-air flues in communication by flues and dampers with the kiln chambers and with the central flue l of the drying-apparatus. The central transverse portion of the wall b encloses a portion of the smoke flue c, which is traversed by tubes or hollow tiles c<3> so as further to heat the air passing to the drying-chambers. Air passages in communication with the atmosphere are also formed in the floor of the kiln as shown in Fig. 2, and above the division walls d, as shown at e, the former leading to the flue l directly, and the latter opening into the flues b. Air may be admitted directly to the flues d by inlets b<2>, Fig. 2. The hollow walls d are perforated as shown and divided into two compartments, either of which, by suitable dampers and flues, can be connected with the flues b. From the flue l branch flues n extend under the division walls between the drying-chambers k<1> ... k<12>, and further branches extend upwards as shown in Fig. 2 through these walls, which are perforated. An exhaust flue extends above the flue l and communicates with the branches o, which also have further upward branches in the division walls. The arrangement of these branches is such, suitable dampers being provided, that the hot air passes through the drying-chambers either in a horizontal or diagonal direction as shown by arrows in Fig. 2. To further heat the air, if required, before it enters the flue l, it is passed through tubes or hollow tiles x heated by a separate fire at w. The smoke flue c may be connected with the exhaust flue of the drying-chambers, or natural draught may be employed.

Title: Improvements in Acetylene Gas Generators.
Filed: 1898-05-26
Granted: 1899-04-01
Abstract: 11,970. British Pure Acetylene Gas Syndicate and Keene, T. May 26. Acetylene. - The generator consists of a tank 1 having a depending plate 2, a partial cover 4, a delivery pipe 5, and an open charging-space through which the carbide receptacle 3 is introduced and placed, beneath the covered portion, by means of the handle 8 pivoted at 7 to the receptacle. The latter has an easily-secured cover 6 in which are one or more perforations which allow water to enter to decompose the carbide, and allow acetylene to escape. The issuing acetylene prevents any more water from entering the carbide receptacle till the rate of generation is diminished. The Provisional Specification further states that a charging-shoot may be provided, and that the charging-opening may, in some cases, have a charging-hopper. The cover of the carbide receptacle may also be almost as deep as the receptacle, and be so much larger that a rubber ring may be inserted between the two, and so that it may rise when gas developes too rapidly, whereby the holes in its top are raised above the level of the water. The lid is pressed downwards by an adjustable spring.

Title: An Improved Process for the Electrolytic Deposition of Nickel or its Allied Metals, or Alloys of these Metals.
Inventor: KUGEL MORITZ
Filed: 1900-02-14
Granted: 1901-01-26
Abstract: 2994. Kugel, M. Feb. 14. Nickel, cobalt, and alloys, depositing.-Nickel, having toughness, durability, and capability of extension equal to rolled nickel, is deposited by employing a nickel salt electrolyte heated to at least 30‹ C., and maintained in an acid condition by the addition of a strong mineral acid which is not chemically changed by the current, such as sulphuric, perchloric, or perbromic acid. To prevent the acidity from diminishing during use, there is added a highly-concentrated solution of a salt of the acid used and of a light metal, which is not changed by the current, magnesium salts being suitable. The process may be used to obtain nickel printing-blocks, and may be also employed for depositing metals allied to nickel, such as cobalt, or alloys of such metals, such as German silver. Ores may be used as anodes, or be immersed in the electrolyte when using insoluble anodes, so as to obtain nickel or allied metals direct from the ores. In all cases the electrolyte is kept well mixed. A current up to 10 to 20 amperes per square decimetre may be used.

Granted: 1902-01-30
Abstract: 6534. Lake, W. R., [Berget, C. X. A.]. March 28. Processes.-Vegetable materials, instead of being treated by the usual chemical processes, are subjected to a fermentation process, which is started by the passage of an alternating electric current and afterwards allowed to proceed spontaneously. The stems of nettles &c. are crushed and made into a thick paste, which is allowed to disintegrate for several days in a liquid containing 4 per cent. of lime. The stems are then drained and piled into a stack a upon a floor c of wire gauze, the wire being supported by uprights d. The stack is covered with a layer e of oakum impregnated with milk of lime and covered with a layer of wire gauze f. The sheets c, f of wire gauze serve as electrodes for an alternating current of electricity, which is passed through the stack for about 8 or 10 hours, the temperature of the material not being allowed to rise beyond 50‹ to 55‹ C. The current is then interrupted and the mass allowed to stand for a day or two, after which it is treated by the ordinary processes in the manufacture of pulp. Dilute hydrochloric acid may be used in the place of milk of lime in the above process.
