Abstract: With the furnace for complete burning down organic matters at accurately determined temperatures, the matters being burned (3) is put into the furnace and that one into a firebox I (1) wherein burning down is carried out at accurately defined temperatures that are < 900 K. Burned down matters (5) exits the furnace, i.e. firebox I (1) at the tempertures < 900 K, under the effect of subpressure in the firebox II (2) are taken into the firebox II (2) thrhough the opening (4), at the outlet part of the firebox II (2), which is of a multiply large surface transverse section and multiply longer than the entry part of the firebox II (2). This incandescent gasses in the firebox II (2) burn down completely at the temperature >1300 K along with the presenc of a large quantity of comprimed air. Drawing unburned gasses into he firebox II (2) from the firebox I (1), there comes to the subpressure in the firebox 1 (1) that enables drawing external air through the openngs (6) and burning down in the firebox I (1). Subpressure in the firebox II (2) is made, as to the Bermuljiev equation, by injecting large quantity of comprimed air through the input part of the firebox II (2) being multiply shorter and of mulftiply smaller surface of transeverse section. Final products of burning down unburned gasses from the firebox I (1) in the firebox II (2) are H2O in the firebox II (2) and CO2 compound being undangerous to environment, withdraw up into the atmosphere.

Title: Improvements in Sunshine Recorders.
Inventor: DINES WILLIAM HENRY
Filed: 1897-04-26
Granted: 1898-03-12
Abstract: 10,363. Dines, W. H. April 26. Sunshinerecorders. - The blackened bulb B, Fig. 2, contains a volatile liquid which, when the sun shines, drives mercury up the tube A and throws the balance over on the pivots a. By this means circuit is complete at the points D or C on the lever E according to whether the sun is shining or no. The circuits through the electromagnets G and H of the recorder, Fig. 6, are thus completed alternately but only momentarily, for, when G is vitalized, the bent armature I, I swinging on its pivot pin withdraws a contact-pivot j<2> from a mercury cup g<1> included in the circuit of the said magnet G, so cutting off the current. A similar arrangement j<1>, h<1> at the other end of the armature is provided for the magnet H. The socket K, carrying an arm k<1> and fountain pen L, rocks with the armature and retains the same in either position until a current again flows. These movements bring the pen into contact with or away from the diagram drum, which is rotated by clockwork.

Title: Improvements in Electric Furnaces and Processes of Treating Ores.
Inventor: BURTON GEORGE DEXTER
Filed: 1897-06-29
Granted: 1898-06-29
Abstract: 15,472. Burton, G. D. June 29. Roasting ores; metals, extracting.-Ores are dried, roasted, and smelted in furnaces in which the heat is produced by passage of electric current either through a metal or other conducting-coil, or a carbon rod, covered by the ore, or through a body of ore placed between two electrodes. Reducing-agents may be mixed with the ore. Alternating current is preferably used, and regulated to increase the heat in successive stages of the treatment. In the furnace shown, a glazed fireclay body A contains a perforated hollow helix S<1> on a pipe S, which is rotatable by gearing H to stir the ore. A coil of pipe may replace the pipe and helix S<1>. The pipe &c. may be made of a copper-antimony alloy. Electric current is passed through the pipe and helix by terminals and clamps E, F. Air may be introduced through the pipe by a lower valve V, and gases are delivered through an upper valve V<2>, or through a valve P' and a tube P made in sections. This contains baffles to stop particles deposited by the gas, and may be provided with magnets to stop magnetic particles ; it ends in liquid in a tank W. Liquid products are discharged at tapping-hole R in the base, which rests on radially-removable supports B'. When the current is to be passed through the ore itself, the tube S is divided, each part carrying a perforated disc electrode, in place of the helix S' ; the upper part of the tube, with its electrode, is vertically adjustable.

Granted: 1898-12-10
Abstract: 2162. Lowe, H. Jan. 27. Steam-generator furnaces; smoke-consuming.-The furnaces and dampers are so arranged that smoke from a freshly-charged fire is made to pass over an incandescent fire. In applying the invention to an existing two-flued boiler, the arrangement shown in sectional plan in Fig. 3 is adopted. A casing e, with fire-doors, is fitted over the front of the two flues, its base being on a level with the firebars, which are prolonged to the ends of the flues. Dampers i are fitted behind the bridges, as shown. One furnace having been fired, its damper is closed, and the smoke and gases pass through the casing and over the bright fire in the other furnace. In a new boiler the casing is dispensed with, a connection between the front ends of the two furnaces being made as shown at m in dotted lines. A similar connection may be made behind the dampers at m<x>. In the case of a single-flued or externally-fired boiler, a partition wall is placed in the furnace to divide it into two parts, each of which is fitted with a damper.
