Title: Processes for the production of iron castings with a low carbon content
IPC: C21C1/08
Filed: 1925-06-11
Abstract: 244,405. Emmel, K., and Thyssen & Co., Akt.-Ges. Dec. 9, 1924, [Convention date]. Purifying and refining. - Iron castings of low carbon content are produced in a cupola furnace worked with solid fuel by smelting of a mixture of 50 per cent or more of iron low in carbon (steel or wrought iron) and iron richer in carbon (pig or brittle iron), with the usual additions for producing grey cast iron and coke amounting to 9-13 per cent of the total charge and submitting the charge to a blast of 400-800 mm. water gauge pressure, according to whether the carbon content of the product is to be nearer 2 or 3 per cent. Part or the whole of the iron low in carbon may be in the form of small pieces which are briquetted before use. In the Specification as open to inspection under Sect. 91 (3) (a), it is stated that the charge may comprise iron low in carbon alone, and that the amount of the carbon in the product is determined by regulating the amount of the blast or the pressure either by throttling the gases escaping from the furnace or by automatic pressure-reducing or regulating valves fitted to the blast pipe. The valves may be adjustable. This subject matter does not appear in the Specification as accepted.

Title: Process and apparatus for mixing a liquid with powder liquid or gaseous substances
Inventor: STEULER GEORG
IPC: B01D47/06
Filed: 1966-04-05
Abstract: 1,148,434. Contact apparatus; continuous mixing; contacting gases with liquids. G. STEULER. 5 April, 1966 [5 April, 1965], No. 15181/66. Headings B1C, B1F and B1R. Liquids are mixed with liquids, powders or gases in a system comprising a combination of at least two direction-changing circulation chambers in series, each chamber being of disc or annular form which the liquid enters tangentially through an inlet of diameter substantially equal to the thickness of the disc or annulus and leaves axially at high speed through an outlet which tapers conveniently in the direction away from its junction with the chamber, which junction is rounded. Various applications to neutralization processes are described. Thus, in one embodiment, a liqluid stream to be neutralized is supplied under pressure through conduit 1, and is then divided into streams 2 and 7. To the former, neutralizing agent is supplied from silo 4 in chamber 3 before it passes tangentially into a helical groove 8 in mixer 9. This first stream then passes up, over overflow 10 and into funnel 11 which also contains a bundle 'of tubes 12 through which the second stream flows, so that both streams are distributed over the entire cross-section of tube 11. Mixing is completed in direction-changing circulation chambers 14 having tapering axial outlets 15. A signal from electrode 5 controls the flow of neutralizing agent in conduit 6. From the mixer chambers, the stream passes by funnel 16 to settler tank 17 having overflow channel 21 for liquid and worms 19 for the removal of sludge.

Title: Improvements in the working up of distillable carbonaceous liquids containing substances of high molecular weight
Filed: 1929-05-15
Abstract: 332,336. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 15, 1929. Hydrogenation, destructive. - In obtaining valuable hydrocarbon products from carbonaceous liquids containing substances of high molecular weight, the latter are removed from the liquids by adsorbents, and are destructively hydrogenated together with the adsorbents at elevated temperatures and pressures. The treatment with adsorbents may be carried out at ordinary or elevated temperatures, and the treated liquid mav be worked up further in any desired manner. Suitable adsorbents are silica gel and alumina gel; preferably the adsorbent should also be a destructive hydrogenation catalyst, such as molybdic acid, or alternatively should be impregnated with such a catalyst. The adsorbent may be used in a colloidal state. After the destructive hydrogenation the adsorbent may be regenerated and used again. In an example, a middle oil containing 7 per cent of constituents boiling between 325‹ C. and 350‹ C. and 5 per cent boiling above 350‹ C. is treated at 70-80 C‹. with a silica adsorbent which has been made catalytic by impregnation with a solution of the nitrates of molybdenum and zinc, followed by heat treatment. The middle oil is separated by centrifuging from the adsorbent and is destructively hydrogenated at 440-450‹ C. and under a pressure of 200 atmospheres of hydrogen in the presence of a catalyst containing molybdic and chromic acids. The activity of the catalyst remains practically unimpaired, whereas, without the preliminary treatment with adsorbent, poisoning occurs rapidly. The adsorbent and adsorbed substances are treated with hydrogen at 460‹ C. and 200 atmospheres. and the low-boiling products formed are returned to the main process. The adsorbent is preferably regenerated by heating for re-use.

Title: Improvements in recorders for watchmen and others periodically travelling a regular beat
IPC: G07C1/20
Filed: 1924-06-24
Abstract: 225,786. Jackson, J. E. Evans-, (Chad wick, E. D.). June 24, 1924. Checking watchmen. - In portable recorders of the type having a record sheet on which distinctive records without regard to time are made by keys located at different stations, means are provided for advancing the sheet bv the key after the record has been made. The paper record disc 10 is supported by a fixed plate 14 within a locked case 12, and is removably fixed to a shaft 16 passing rotatably through the plate 14 and carrying a wormwheel 17 meshing with a worm 18. Fixed to the shaft of the worm is a ratchet wheel 24 with which engages a pawl 24<1> mounted on a spring- pressed pivoted lever 30. When the key 25 is inserted and turned it engages a pin 32 on the lever 30 and swings the lever to retract the pawl 24<1> one tooth, this movement causing the part 26 of the key, carrying an identifying character, to press the record disc into the matrix 26<1> to make the record, the force of the blow being standardized by a spring-pressed obstructing lever 27. The return movement of the key allows a spring 31 to return the lever 30 and cause the pawl 24<1> to advance the ratchet wheel 24 one tooth thus advancing the record disc 10. A detent 33 prevents backward movement of the ratchet wheel. If the angular rotation of the disc for each operation is not exactly divisible into 360‹ the, same disc may make a number of rotations without the record becoming superimposed. The identifying character may be placed at different positions on the keys so that the record has a spiral form. In a modification, only the last key of a set is provided with means for engaging the pin 32, so that the disc is advanced one step at the end of each trip. A device 34 is provided for making an impression on the disc each time the cover of the case is opened.

Abstract: 401,767. Rotary retorts for destructive distillation. BRITISH COAL DISTILLATION, Ltd., (formerly LEICESTERSHIRE (L. & N.) COAL DISTILLATION, Ltd.), and MACHEN, C., 48, Broadway, Westminster. May 30, 1932, No. 15277. [Class 55 (i).] In the distillation of coal or the like in rotary retorts containing a number of tubes through which the charge passes, the heat required is supplied partly by the passage of a heated gas in contact with the charge, and partly externally of the tubes, the whole of the heating gases being supplied from a chamber at one end of the retort. The coal is charged from a hopper 1 into a dryer 4 heated by gases from a rotary retort into which it is fed by a shoot 6. The retort is similar to that described in Specification 324,212, [Class 55 (i), Coking &c.], and contains tubes 9 through. which the coal passes, and in which it is heated partly by contact with hot gases from a combustion chamber 24, and partly by external heating of the tubes. The external circulating gas passes through ports 13 in the retort shell into an annular chamber 14, pipe 15, main 33, fan 34, and pipe 35 to the dryer, from which it returns by pipe 5a to the combustion chamber. The distillates and internal heating gases are withdrawn by a fan 19 through a cyclone 17 and condenser 18, and pass through a scrubber 20 and gas holder 21, from which a pipe 22 leads to a burner 23. The proportion of internal to external heating gas is controlled by operation of valve 19a and fan 19 together with fan 34 and valves 25 and 36a. A stack 37 leads cooled exhaust gases to the atmosphere. A gas-sealed gland 31 is arranged between the rotary retort and the stationary pipe 16, gas pipes 32 connecting the gland 31 to the pressure side of the fan 34. The tubes 9 in the retort are fitted with steel bars 10 serving as heat conductors, and are supported by plates 9a, leaving ports 12 through which the external heating gases pass. In an example, the heating gases entering by the common inlet 27 at 650‹ C. are divided into an externally applied volume of 45000 cubic feet per ton of coal, and a volume of 20000 cubic feet of carrier gas.
