Title: Process and apparatus for making combustible gas
IPC: C10B49/08
Filed: 1936-08-28
Abstract: 480,955. Gas manufacture. STRYKER, A. R., and TIETIG, C. Aug. 28, 1936, No. 23668. Convention date, Sept. 30, 1935. [Classes 55 (i) and 55 (ii)] In the production of combustible gas by showering finely divided solid or liquid hydrocarbonaceous material or passing a gaseous hydrocarbonaceous substance downwardly through a zone of sufficient length and temperature to gasefy the material, the gases are withdrawn from an incandescent fuel bed maintained at the bottom of the zone. The starting material, which may comprise solids such as coal, mine refuse, wood, sugars, straw, corn stalks, and coconut, liquids such as petroleum, gas oil, still bottoms, kerosene, butane, ethylene, cotton seed oil, fats, and fatty acids, or gases such as natural gas, refinery gas and coal gas, is fed to the top of a retort 10 superimposed above an intermittently operated generator 17. Before the gas making operation, the fuel bed, preferably coal, is raised to incandescence by up and down blasting with air supplied through inlets 58 and 62, with or without steam introduced through inlet 61. The gas obtained is vented through stack 72<1>, and heating is continued until the retort reaches a temperature of about 1400‹ F. During the heating operation steam is generated in a waste heat boiler 34 arranged in the offtake 33, and is utilized to operate a turbine connected to an exhauster 67 which creates the necessary suction in the generator during the gas making stage and withdraws the generated gas through offtake pipe 60 to a wash box 39. The gas is withdrawn at any desired level from the fuel bed through apertures 52, Fig. 3, in the bricks composing the lining of the generator which communicate with channels 53 therein. Each of the latter is connected at four equidistant points with corresponding exterior valvecontrolled manifolds 46, which latter discharge into the offtake pipe 60. The gas may also be withdrawn beneath the grate, the hydrogen content of the gas increasing with depth of withdrawal. The fuel bed is maintained by coal or coke fed thereto from a hopper 19 through ports 18. The retort-generator may be 80 to 90 feet in height and preferably of double conical shape ranging from 11 feet at its widest part to 4 feet at its apex.
Patent GB-1043377-A (GB)
IPC: C01B3/38
Filed: 1964-06-08
Abstract: A methane-containing gas is made by a two-stage process from paraffinic hydrocarbons.  The first (gasification) stage, which is a reaction with steam over a nickel catalyst, is similar to that described in Specification 1,000,309.  In the second stage, the gas is catalytically steam-reformed, optionally with added steam, at a temperature above 550 DEG  C., after being preheated in an externally fired heater, to decrease the methane content of the final gas.  The second stage may comprise more than one pair of preheating and reforming steps.  The catalyst used in the gasification stage may be one described in Specification 969,637. Four specific examples are described.

Abstract: Freshly-cut meat, e.g. animal, fish or poultry flesh, is preserved by applying to its surface a broad-spectrum antibiotic, e.g. tetracycline, chlortetracycline, oxytetracycline, or chloramphenicol, and nystatin and/or myprozine, so that 0.5 to 500 parts per million of mystatin and/or myprozine, based on the weight of the meat, are retained on it.  The meat may be immersed in an aqueous solution containing 6 to 1000 p.p.m. of the broad-spectrum antibiotic and from 10 to 1000 p.p.m., by weight, of nystatin and/or myprozine or dusted with a powder comprising an inert carrier, e.g. common salt, monosodium glutamate, starch, or glucose, and from 0.05 to 10% by weight of the broad-spectrum antibiotic, and of nystatin and/or myprozine.  The antibiotic may be in any water-soluble form, e.g. an alkali metal or alkaline-earth metal salt, a mineral acid salt such as the hydrochloride, or a borate or phosphate complex and the treatment of the meat is preferably effected at 40 DEG  to 50 DEG  F. after which it is tray packed, e.g. on cardboard, and wrapped in film, e.g. of polythene or regenerated cellulose.  Specification 846,933 is referred to.

Title: Preparation of aluminium sulphinate gelling agents
IPC: B01J19/06
Filed: 1960-07-13
Abstract: An aluminium sulphinate gelling agent having the formula Al(SO2R)3, in which R is an alkyl group, is obtained by reacting a trialkyl aluminium compound with sulphur dioxide at a temperature in the range from -75 DEG  to 50 DEG C. to avoid gellation of the reaction mass, in the presence of a solvent for the resulting reaction product, the solvent having a boiling point above the reaction temperature used, and then removing the unreacted sulphur dioxide.  Suitable trialkylaluminium compounds are, for example, those in which the alkyl groups contain up to 20 carbon atoms such as trimethyl, triethyl, tributyl, tripropyl and tridodecyl aluminium.  Suitable solvents include the higher boiling ethers, heterocyclic nitrogen bases, disubstituted amides and aliphatic and aromatic hydrocarbons. The preferred solvents are tetrahydrofuran, pyridine and dimethyl formamide.  If hydrocarbons are used as solvents the gelling agent must be formed at a temperature below -10 DEG C. or a gelled composition is obtained.  The gelling agent may be used to gel a hydrocarbon or a mixture of hydrocarbons.  Hydrocarbons may be gelled by the addition of 4% by weight of the gelling agent followed by mild heating and stirring.  Reference has been directed by the Comptroller to Specification 819,181.

A feed leg for a drill comprises an outer cylinder closed at one end an elongated central member within and affixed thereto, an intermediate cylinder within the outer cylinder and having a head portion slidingly engaging the inner surface of the outer cylinder and the surface of the central member, and an inner cylinder having a portion slidingly engaging the inner surface of the intermediate cylinder, the central member having passageways for the distribution of pressure fluid. As shown, an outer cylinder 21 closed at the top, to which a drill may be attached, has a central shaft 24 having on its free end a head 26 with grooves 25. An intermediate cylinder 22 has a head 27 slidingly engaging the outer cylinder and having a hole which slidingly engages the shaft 24. An inner cylinder 23 has a flange 34 which slidingly engages the inner surface of the intermediate cylinder. Compressed air is supplied to the outer cylinder through bores 37, 38 and causes the outer cylinder to move away from the cylinders 22, 23. When the outer cylinder is fully expanded compressed air from that cylinder enters the inner cylinder through bores 41, 39 in the head 26 and causes the inner cylinder to move away from the intermediate cylinder. A flange 36 on the inner wall of the intermediate cylinder limits the movement of the inner cylinder by engagement with the flange 34, the space between the flanges being vented by a hole 35. The air in the inner cylinder is vented through the grooves 25 and the bores 39 and 41. Examples are given of the application of one feed leg to a drill, Fig. 8 (not shown), of two feed legs arranged parallel to each other one on either side of a drill, Fig. 9 (not shown), and of two feed legs arranged parallel to each other and a third leg operating in tandem with the parallel legs, Fig. 11 (not shown).
