Title: Improvements in Grain Separators.
Inventor: FELL JOHN CORRY
Filed: 1899-02-02
Granted: 1899-03-25
Abstract: 2374. Fell, J. C., [Tromanhauser, S. H.]. Feb. 2. Sifting and separating grain.-Grain fed into the hopper 5 through the spout 6 passes by a pair of spouts 7 and 8 to oppositely-disposed tapering screens 10, 11, rotated by frictional contact of their circular end plates with the rotating trunnions 14. The screens are furnished with apertures diminishing in size towards their open ends, where straw &c. is discharged. The grain falling upon the plate 18 passes the balanced valve 21, and is directed upon the inclined glass plate 23, being aspirated as it falls by air drawn by fans 28 through the passages 39<a>, 35<a>, 34 into the expansion chamber 33. A dust-collecting chamber 35 is placed in the path of the dust-containing air, which is also exhausted through the passages 38 and 41<a>. The air currents in the passages 39<a> and 41<a> are regulated by valves. The heavier of the small particles removed in the first aspiration are collected in the trough 24, and seeds &c. are collected after the second aspiration in the trough 46, the purified grain clearing the adjustable barrier 45 and being discharged at 46<1>. Louvres 4 admit air for the second aspiration. The electricfication produced by the friction of the grain on the glass surface retards the small particles and assists the subsequent separation. Separation may be effected without the operation of the fans. Marble, metal, or polished wood may be substituted for the glass plate.

Title: Improvements in and connected with the Manufacture of Acetic Acid and other Acids of the Fatty Acid Series.
Inventor: HOCHSTETTER HEINRICH VON
Filed: 1902-02-15
Granted: 1903-02-05
Abstract: 3923. Hochstetter, H. von. Feb. 15. Fatty acids.-Acetic acid and other fatty acids are obtained from their salts by passing over the latter a mineral acid in a dry gaseous state at a temperature exceeding the boiling point of the fatty acid. When hydrochloric acid is employed, the dry gas is obtained by causing aqueous hydrochloric acid to flow into concentrated sulphuric acid and drying the gas thus liberated. Alternatively, the gases produced in the manufacture of sulphate of soda are used, after being dried by passing through coke towers supplied with concentrated sulphuric acid which is subsequently used for decomposing common salt. Sulphurousacid gas in presence of sufficient moisture for forming H2SO3 may be employed instead of hydrochloric-acid gas. These processes yield a high percentage of fine acid, and the calcium chloride or sulphite produced is obtained as a dry and valuable bye-product. The process may be carried out by passing the hot gaseous acid at a into a retort c charged with pyrolignate of lime, passing the vapours of the liberated acetic acid into a condenser h, and collecting the condensed acid in a receiver i. The temperature of the retort is regulated by heating the entering gas more or less and by passing a greater or less volume of heating- gases through the flues d, or by superheated steam. The retort is fitted with thermometers k. It is charged at b and the residue is removed by means of a detachable bottom f.
