Title: Improvements in Devices for Connecting the Chimneys of Locomotives and the like with the Chimneys of Engine and other Sheds.
Inventor: SPIECELHALTER LUDWIG
Filed: 1903-09-17
Granted: 1903-11-26
Abstract: 20,075. Spiecelhalter, L. Sept. 17. Shafts.- Relates to a device for connecting the chimneys of locomotives and other motor vehicles with the chimneys o f e n - gine and other sheds.

Patent GB-190324144-A (GB)
Title: Improvements in Electrically Controlled Valves.
Inventor: JUNGGREN OSCAR
Filed: 1903-11-06
Granted: 1904-11-03
Abstract: 24,144. Junggren, O. Nov. 15, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Actuating valves lift valves; casings; seats.-Relates to an electricallycontrolled throttle or cut-off valve. The valve proper 12 is mounted on a spindle 11 and a detachable seat 7 is mounted in the casing. Pistons, working in cylinders 8, 9, are also mounted on the spindle 11, and steam can be admitted to one or other of these cylinders, by means of subsidiary valves operated by the electromagnets shown. The controlling-valves work quite independently, one of them acting to open the main valve, and the other to close it. To open the main valve, current is supplied to the electromagnet 20 from the mains 34, 35 controlled by a hand-switch 36. The energized magnet attracts an armature 31 which carries a rod 32. This gives a hammer blow to the spindle 22 of the double-acting controlling-valve 16, which moves downwards and engages its lower seat 17, and so cuts off the supply of steam to the cylinder 9 and puts the exhaust 24 in connection with the steam passage 15. The pressures on the two sides of the right-hand piston are now unbalanced, and so the main valve opens. The left hand piston offers no resistance to the motion as the pressures on its two sides are balanced. As soon as the main valve is fully open, the circuit is broken by the switch 36, and the valve 16 returns to its upper seat 21 under the influence of a spring 18. To close the valve, the left-hand magnet is energized, the action being the same as that described above.

Abstract: 26,846. Brookes, A. G., [McClellon, J. M.]. Dec. 8. Metal pipes and tubes; plates, securing tubes to.- Relates to the pipes and tubes which are employed in a form of locomotive steam boiler comprising water tubes, headers, and drums. The tubes that form the sides of the boiler, which is rectangular in cross-section, are placed in contact, the parts being flattened for that purpose. The tubes may be round or square, or square with round interiors. In Fig. 5, the tubes are shown as having reduced ends 93 which are expanded in place, the groove 98 assisting in the operation. To permit of the removal of a tube, the upper end 93 is made longer than the end 93<a>. To hold the tube in place, the filling-piece 96 is employed. Alternately, bushings screwed into the ends of the tubes may be expanded in the seatings or screwed therein. The ends of the tubes where expanded may be reduced in diameter. When the tubes are square on the outside, bushes with nipples are employed. The adjacent tubes of the firebox are connected together either by rivets or by means of double dovetailed key-pieces 45. Caulking-strips may be placed between adjacent tubes.

Patent GB-190404796-A (GB)
Title: Improvements in or relating to the Extraction or Preparation of Nitrates or similar Salts.
Inventor: STANLEY JOHN CHARLES WILLIAM
Filed: 1904-02-26
Granted: 1904-12-01
Abstract: 4796. Stanley, J. C. W. Feb. 26. Sodium nitrate; salts, purifying.-In the extraction of nitrates and similar salts from caliche; natural soda, borax, salt, &c., particularly sodium nitrate from caliche, the material, after being finely divided, as by crushing and passing through fine-meshed sieves, is treated with water already at or about the boiling point. The caliche, for example, is carried by a conveyer and elevator from the receiving-bins to the crushing-bouse, whence, after grinding and screening, it is taken by a conveyer to storage bins of known capacity above the boiling-tanks. The quantity of boiling water necessary for the extraction, is found by analysis. The caliche is then shot into the boiling- tank A, heated by producer gas and having a central division A<1>, worm conveyers B, and stirrers C. When the boiling point of the liquor is about 240‹ F., the gas is turned off and, after settling, the liquor is run through the pipe A<3> into the tank D, also gas heated and having agitators D'. Heavy impurities, such as sand, are discharged through a valve A<2>. The liquor has its temperature kept up, or raised if necessary, and is then pumped through the pipe D' to the filter-press E and thence through the pipe E<1> to a long V-shaped crystallizing-tank F which is provided with pipes F<1> so that its contents may be artificially cooled by cooled air or otherwise. The crystals which form upon the sides of the tank are drained from mother liquor by tipping the tank and are then detached, as by tipping suddenly so that the tank comes with a shock against a stop. The mother liquor can be returned to the tank A and heated ready for a fresh charge. The crystals are dried first by contact with absorbent material such as felt and then by an air current while they are, preferably, spread in thin layers on a series of travelling bands. Scrapers dislodge the crystals at one end of each band so that they fall on the beginning of the next. The slime from the boiling-tank and the cakes from the filter presses are extracted with warm water for soluble salts and then carried away. If there be much impurity in the caliche, it is convenient to allow the liquor in the tank A to overflow by a pipe A<4> to the tank D and the liquor in the latter to be thinned with some clear liquor from the filter press, flowing through the pipe E<2>. It is also advantageous if some of the clear liquid flows back through the pipe E<3> to the boiling-tank A. The liquor from the filter press often contains some residue of common salt. This may be separated by boiling the liquor until precipitation takes place. In this connection, a valve-controlled pipe E<4> leads from the pipe A<3> direct to the pump and filter press. The pure nitrate liquor then passes to the tank F leaving the salt in cakes in the press. An arrangement of the plant, which is conveniently in duplicate, is described.
