Title: Improvements in carbon black
IPC: C09C1/50
Filed: 1950-06-22
Abstract: <PICT:0687867/III/1> Furnace black is rendered more adsorptive by subjecting it in suspension in products of combustion containing uniformly dispersed therein 0.1 to 2 per cent free oxygen to temperatures within the range of 2000 DEG F to 2500 DEG F for a period of time within the range of 0.1 to 0.5 seconds.  The treatment is preferably effected in the carbon black furnace in a zone just subsequent to that in which the carbon black is formed, for example by mixing about 5 per cent air by volume with the furnace gases resulting from combustion and decomposition of hydrocarbons with insufficient air to complete combustion.  In the preferred embodiment, Fig. 1, air and fuel gas are injected from pipes 9 and 11 respectively into a burner block 6 at one end of an elongated combustion chamber 1, the apparatus being of the type disclosed in Specification 654,865.  Hydrocarbon to be decomposed is injected to the furnace from an annular pipe 15 through radial jets 16, the trajectory of the jets being so controlled that the streams fail to meet and thus leave a channel through which oxygen containing gases may pass, such oxygen becoming intimately mixed with the make gas after the latter has been decomposed to form carbon black in suspension.  Specifications 654,864 and 673,401 also are referred to.

Title: Improvements in or relating to methods of and apparatus for the heating or cooling of liquids or admixed solids and liquids in evaporative or like treatment thereof
IPC: B01D1/28
Filed: 1921-06-16
Abstract: 188,703. Rigby, T. June 16, 1921. Micltiple-effect apparatus; vapours, utilizing for effecting further evaporation.-Relates to multiple-effect apparatus in which vapour from the final effect or from one of the final effects is compressed and used as heating-medium in the first effect or one of the first effects. The energy required for the compression is derived from a natural direct source of mechanical energy, such as a fall of water, and heat losses are made up by steam from an electrically-heated boiler, the energy for which is derived from the same source. The ordinary steam supply and condensing arrangements are retained in order that the amount of evaporation effected by the steam and by the energy of compression may be varied. Liquid is added to the vapours before or after compression, so as to absorb the superheat and generate make-up vapours. As applied to the apparatus described in Specification 187,260, in which a number of multiple effect plants with overlapping temperature ranges are used, and in which the final effects of each plant are connected to a main 7 which leads by a valve 13 to a condenser 9, a branch pipe provided with a valve 15 leads to a compressor 17, the compressed vapours being led by pipes 25, 27 to the heating- spaces 21, 23 of the first effects of each plant. The condensates from each effect are cooled by flashing off vapour into effects at lower pressures and pass by a main 33 to the condenser 9. The liquid to be evaporated fed through a pipe 45 may be preheated in coils 65, 67 by the vapours before or after compression and by non-condensible gases withdrawn from the heating spaces of the first effects of each plant by valved pipes 41, 43. Non-condensible gases from the later effects are withdrawn by pipes 37, 39 leading to the main 7. The liquid to be separated is fed in parallel to the effects of each plant and the concentrated liquid is withdrawn in parallel through pipes 53, 55, vapours being flashed off to cool the liquids by connections 57, 59 to effects at lower pressures. Steam may be supplied to the heating- spaces of the first effects from an electrically heated boiler 69.

Title: Improvements in the conversion of hydrocarbons into gases containing methane, carbonmonoxide and hydrogen
IPC: C01B3/38
Filed: 1958-05-23
Abstract: 854,150. Combustible gas; purifying gas. GERHOLD, M. May 23, 1958 [May 27, 1957], No. 16614/58. Drawings to Specification. Class 55 (2). Liquid or gaseous hydrocarbons containing organic sulphur compounds are converted into a gas containing methane, carbon monoxide and hydrogen by first passing the hydrocarbons, after vaporization in the case of liquid hydrocarbons, together with hydrogen or a hydrogencontaining gas and at an elevated temperature, e.g. between 400‹ and 500‹ C., over a catalyst which promotes the reaction of organic sulphur compounds with hydrogen to form hydrogen sulphide, and then passing the resulting mixture together with free oxygen or steam into a conversion zone at a higher temperature, e.g. between 780‹ and 1000‹ C., and preferably containing a dehydrogenation or a cracking and a reforming catalyst to produce the desired gas. Product gas may be recycled to provide all or some of the hydrogen for the first part of the process and in this case free carbon is removed from all or part of the product gas by passing it, if necessary together with additional free oxygen and/or steam, over an oxidation catalyst at a temperature between 900‹ and 1000‹ C. Liquid hydrocarbons may be vaporized in the presence of the hydrogen-containing gas to be used in the step for removing organic sulphur compounds. Catalysts suitable for promoting the reaction of organic sulphur compounds with hydrogen are oxidic, preferably non-hydrating, compounds of elements of the second, third and fourth groups of the Periodic Table. In the conversion zone suitable cracking catalysts are crystalline oxidic compounds of elements of the second, third and fourth groups of the Periodic Table and suitable reforming catalysts, i.e. catalysts which promote reaction between products from that part of the conversion zone containing the cracking catalyst and steam, are metals such as nickel, cobalt and chromium, oxides such as chromium oxide, cobalt oxide and tungstic oxide, sulphides such as nickel sulphide, molybdenum sulphide or an inert carrier, e.g. crystalline mixed compounds of alumina and silica or magnesia and silica. Oxidation catalysts for use in the removal of carbon from the product gas are oxidic compounds of metals of the sixth, seventh and eighth groups of the Periodic Table, particularly chromium oxide. The oxidation catalyst may be in the form of shaped bodies the surface of which contains about 5% of the catalyst.

Title: An improvement in automatic electric circuit breakers with time lag thermal release
IPC: H01H71/52
Filed: 1951-07-13
Abstract: 686,516. Automatic circuit-breakers. LANDIS & GYR SOC. ANON. July 13, 1951 [July 15, 1950], No. 16711/51. Class 38 (v) In a thermally-released, automatic circuit-breaker one of the "releasing" parts is of metal and the other is of glass so that the frictional resistance between them is low and substantially constant. In Fig. 1, the circuit-breaker contacts 1, 2 are held closed by an overset toggle 7 extending between levers 3 and 8, which are pivoted at 4 and 9 and biased by tension springs 6 and 10, respectively. A bell-crank lever 14 is biased by a spring 15 and has a glass plate 18 abutting a knife-edge 20 on a metal bell-crank lever 13. Under excess-current conditions, a bimetallic strip 12 turns the lever 13 about its pivot until the knife edge 20 slips off the edge 19 of the plate 18. The lever 14 is then turned by the spring 15 so that its arm 14<SP>1</SP> strikes a projection 17 to collapse the toggle 7. The lever 3 is turned about its axis 4 by the spring 6 to open the contacts and at the same time to reset the lever 14 by means of a link 16, so that the knife edge 20 can re-engage the glass plate 18 on the cooling of the bimetallic strip. The relaxing of the pressure on the lever 8 by the toggle 7 enables means (not shown) to move the operating lever 11 to the off position, so that the spring 10 is able to reset the toggle 7, and the circuit is then automatically reset ready for reclosure. In a modification, Fig. 2 (not shown), the lever 14 has a cylindrical glass part which normally abuts a transverse surface on the lever 13.
