Filed: 1975-08-26
Abstract: 1470724 Synthesis gas production TEXACO DEVELOPMENT CORP 26 Aug 1975 [26 Sept 1974] 35158/75 Heading C5E A method for the continuous manufacture of a gas containing principally CO and H 2  comprises introducing, into an unpacked free flow synthesis gas generator 21, a first slurry 30 of particulate carbonaceous fuel in a liquid hydrocarbon fuel, a second slurry 1 of particulate carbonaceous fuel and water, and a stream 40 of free-oxygen-containing gas interposed between the streams of the first and second slurries so that the three streams may be intermixed and produce an atomized dispersion which is caused to react at a temperature of 1500- 3500F. to produce a gaseous effluent stream 42; in the atomized dispersion, the atomic ratio of oxygen to carbon in the total fuel is 0À6-1À6, the weight ratio of H 2 O to fuel is 0À1-1À3, and the weight ratio of total solid carbonaceous fuel to liquid hydrocarbon fuel is 0À8-12, and the first and second slurries are introduced into the gas generator at a velocity of 1-500 feet per second. The effluent stream 42 may be split into a first stream 43 which is cooled in a waste heat boiler 44, scrubbed with oil at 56 and then with water at 69 to give a desired product gas stream 76 containing principally H 2  and CO containing less than 10 mole per cent H 2 O. The particulate carbon/oil dispersion obtained in knockout pot 61 following scrubber 56 is in part recycled to the gas generator 21 via line 33 and a grinding system 31 which grinds carbonaceous fuel 32, and in part fed back into the scrubber 56. A second stream 47 of the effluent 42 from the generator 21 is passed through a water quench tank 48 from which a gas stream 49 containing CO and H 2 , saturated with water, is produced. The separated dispersion 79 of solids and water is mixed with the dispersion 77 obtained from a water knockout pot 75 following the water scrubber 69 for the first stream, and is treated in a settling tank 80, froth flotation zone 85 and then passed to mixing tank 24, which is fed with ground coal 25 to give a slurry which provides the feed 1 to the gas generator. The first and second slurries and the oxygen-containing gas may be introduced into the gas generator using a multiple annulus burner 4 as illustrated in Fig. 2. The liquid hydrocarbon slurry is fed in through central conduit 7, oxygen through intermediate conduit 5, and water slurry through conduit 2. Numerous solid carbonaceous fuels and liquid hydrocarbons which may be used in the process are mentioned.

Abstract: 880,654. Interrupters. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. Oct. 19, 1959 [Oct. 24, 1958], No. 35241/59. Class 38 (5). Timing adjustment of an ignition contactbreaker in accordance with the degree of suction in the induction system of an I.C. engine is obtained by movement of the operational axis of the arm about a second stationary axis located inside the arm pivot hole or bush. A movable breaker-arm 2 having a bearing bush 3 is pivoted on a cylinder 5 which is in turn eccentrically pivoted on a fixed pin 7. The cylinder 5 has an arm 8 rigidly secured thereto and coupled to a control rod 4 which is operated by a diaphragm, for example, responsive to engine induction vacuum. This arrangement reduces the reaction force on arm 4 due to the cam impact on arm 2 and also results in a self-cleaning wiping action of the two contacts due to the repeated angular movements of eccentric 5. The cylinder 5 and rod 8 may be made in one piece (Figs. 3 and 4, not shown).

IPC: B01D3/42
Filed: 1946-12-05
Abstract: <PICT:0640704/III/1> In distillation columns the vapours are passed up through vertical elements such as tubes, the upper ends of which are surrounded by a liquid maintained in a casing, and the pressure within the casing is controlled by a valve in an outlet pipe from the vapour space of the casing so that the liquid therein boils, thereby abstracting heat from the process vapours, at such a temperature that a falling film of reflux liquid is maintained on the inside of each element.  The level of the boiling liquid inside the casing may also be controlled.  The distilland is vaporized and led into column 1, the upper part of which contains vertical tubes 3.  The upper ends of the tubes pass through casing 5 which is supplied with cooling liquid by means of pipe 10.  The vapour generated from the liquid boiling in the space between the tubes is led away through pipe 15 controlled by valve 16.  The process vapours which are not condensed in tubes 3, are led by pipe 7 to the main condenser 8 of the system.  Casing 5 is divided by means of foraminated plates 9 into several superimposed compartments, each of which is separately connected to one of a series of pipes 11 which lead, through valves 12, to manifold 14 and condenser 8. By these means the level of the liquid between the tubes can be varied, and the same liquid used as coolant in both condensers.
