Filed: 1903-03-24
Granted: 1903-05-07
Abstract: 6824. Clark, A. M., [Ferguson, W. C.]. March 24. Sulphuric anhydride. -Relates to the catalytic process for manufacturing sulphuric anhydride from sulphur dioxide and oxygen, which preferably contains a larger proportion of sulphur dioxide than usual, e.g., 11 per cent., into contact with the catalyte, so as to convert only a portion of the sulphur dioxide into sulphuric anhydride. The partially-converted product, which is relatively poor in oxygen, is carried away from the catalyte, and a suitable amount of air, or gaseous medium containing a larger proportion of free oxygen than the original mixture, is added to it for the purpose of cooling it and for supplying additional oxygen. This latter mixture is brought into renewed contact with a further quantity of the catalyte, to continue the conversion of the sulphur dioxide into sulphuric anhydride, and these operations may be repeated. The apparatus, Fig. 1, comprises a plurality of contact chambers B, B<1>, connection pipes C, C<1> from the outlet of one chamber to the inlet of the next, and an air-supply device G leading to pipes E, E' branched on the connection pipes C, C<1>, so that the cooling of, and addition of oxygen to, the partially-converted product may take place while it is away from the catalyte.

Title: An Improved Method and Means for the Production of an Aseptic Germ-proof Closure for Bottles
Inventor: SEIFFERT MAX
Filed: 1903-05-06
Granted: 1904-04-07
Abstract: 10,337. Seiffert, M. May 6. Stoppers; stoppering; capsuling and sealing bottles.-Relates to an aseptic germ-proof closure for bottles used for containing milk, serum, or other liquids, which are liable to decomposition by bacterial action. The closure, Fig. 1, consists of a disc 1 of tinfoil free from lead, having on the side next the bottle mouth a coating 2, which consists of a 3 to 5 per cent. aqueous solution of carrageen moss or agar-agar, with 0.5 to 1 per cent. of pure glycerine, the coating, which is adapted to swell under the action of water or steam, being applied to the surface of the foil, allowed to congeal, and dried. Sheets of the foil may be coated in this way, cut into strips, and wound into rolls, which are enclosed in a paper packing slotted to permit their removal. The strips are perforated, at intervals, in circles corresponding in diameter with the width of the closures. The rolls may be sterilized in a dry heat at 150‹ C. Fig. 3 shows an apparatus for use in applying the closures, when the foil is comparatively thin and can be compressed round the bottle neck in folds. A number of segment-like pieces 7 arranged in iris form are pivoted at one end to the lower ring 5 of the annulus 4, and, at the other end, are provided with pins 9, which engage in slots 10 in the revoluble ring 11. By rotating the ring 11 in the proper direction, the pieces 7 are closed inwards to fold and secure the closure on the bottle neck. When the neck has a constriction or the like, the closure may be pressed into it, and tied with a wire or string ; or, a paper strip may be stuck over it. In the modification shown in Fig. 5, which is adapted for closures with thicker foil, the pieces 7 are replaced by three slides 15, 16, &c., having pins 18, 19, &c. engaged in cam-slots in the ring 24, the inner ends of the slides forming, in conjunction with each other, a cylindrical surface, which presses the closure uniformly over the bottle neck when the slides are forced inwards by the rotation of the ring 24. Fig. 7 shows a mechanical arrangement for applying the closures, the ring 11, Fig. 1, or 24, Fig. 5, being provided with a worm-wheel 12, or 25, which, as shown at 45, Fig. 7, is adapted to be rotated by the worm 46 actuated by the hand-driven gearing 47, 48. The bottle 42 is placed on the rest 38, and is raised by the rack-and-pinion mechanism 37, 36 actuated by the treadle 35, so that it tears the closure from the strip 43, and moves up to the abutment 44 &c. into position for the closure to be applied. The strip 43 is drawn from the roll 58 on to the roller 56, or on to a roller 59 controlled by a spring or weight, the roller 56 being actuated through the ratchet mechanism 54, 53, by the tappet 49 on the bottle rest raising the lever 51 connected to the pawl 53, on the upward movement of the rest. The strip 43 is protected from the air by casings 60, 61.
Patent GB-190311126-A (GB)
Title: Improvements in Apparatus for Separating Air into its Constituent Gases
Inventor: DUMARS HORACE
Filed: 1903-05-15
Granted: 1903-08-06
Abstract: 11,126. Dumars, H. May 15. Nitrogen; oxygen.-Relates to means for separating oxygen and nitrogen from liquid air by fractional distillation, comprising arrangements of counter-current interchangers with triple pipes for liquefying compressed air by its expansion, or by evaporation of the liquid air already produced. Two receivers i, i<1> for liquid air are enclosed in a vacuum casing 2, and provided with compressedair liquefying-coils 4, 4<1>, forming, respectively, continuations of two branches of the intermediate compressed-air pipe 7 of the triple-interchanger coil, the end only of which is shown. Each branch is fitted with a stop-cock. Each coil opens through a non-return valve into the receiver enclosing the other coil. A single receiver 3 for liquid oxygen communicates by pipes with stop-cocks with the two liquid-air receivers. One receiver being filled with liquid air, by the operation of the interchanger, or otherwise, compressed-air from the interchanger coil is passed through its immersed coil 4 or 4<1> and, being liquefied therein, is delivered into the other receiver. The nitrogen in the liquid air surrounding the coil is thus evaporated and escapes through the outer pipe 9 of the interchanger coil. When four-fifths of the liquid air is evaporated, the remainder, which consists of liquid oxygen, is run into the receiver 3, where it is evaporated by the heat of the atmosphere, and the oxygen gas escapes through the pipe 10, which forms the inner pipe of the triple-interchanger coil. In a modified arrangement, the nitrogen is passed through the central pipe of the coil, and the oxygen through the outer pipe. The air, before its initial compression, is dried by passing through a cylinder containing calcium chloride or other hygroscopic substance on perforated trays. It is then cooled by water in an ordinary double coil, after which it may be used to drive the engine that works the compressor. It is then delivered to the compressed-air coil of the interchanger.

Granted: 1904-09-12
Abstract: 13,199. Ferranti, S. Z. de. June 12. Steam &c. turbines. -Consists in generating a superheated mixture of steam and gas and extracting the energy from it by means of one or more turbines. One form of apparatus is shown diagrammatically in Fig. 4. Steam from a boiler a passes through an external superheater b to two similar internal superheaters c. The internal superheaters have a liquid, gaseons, or pulverulent fuel supply i, Fig. 1, which is mixed in a nozzle f with compressed air from a compressor n. The steam from the boiler passes into the outer chamber l, or feedwater may be circulated through this chamber, and through openings m into an inner chamber d, in which the gaseous mixture is burnt, and the superheated mixture then passes through one or more expanding nozzles e to the turbine s. The exhaust steam from the turbine may be used to heat the boiler steam, feedwater, or compressed air for combustion. As shown in Fig. 4, a pump z draws water from the hot well x and circulates it through coils 3 in a chamber s<1> through which exhaust steam from the turbine passes. This feedwater is then passed through a coil 6 in the boiler uptake and is then supplied to the boiler. Modified forms of internal superheaters are described. In a modification, the exhaust gases from the first turbine are passed through a tubular steam generator and the steam generated is used to drive a second turbine preferably of the kind described in Specification No. 24,781, A.D. 1902. Another modification has a feedwater heater 6, Fig. 6, in the furnace flue adjoining the steam generator 20 whence the steam passes to a superheater 22 and then to the internal superheaters c and primary turbines s. The condensed steam from the primary turbine is drawn from the auxiliary boiler 8 by the feedpump 15 and passes to the feedwater-heater. Steam from the auxiliary boiler passes through a superheater 21 in the furnace and then to the second turbine 11, which is connected to a jet condenser 12. In another modification, steam for the combustion chambers is generated in an auxiliary boiler by the exhaust gases from the turbine.
