Filed: 1928-11-22
Abstract: 301,902. Siemens -Schuckertwerke Akt.-Ges. Dec. 8, 1927, [Convention date]. Plug couplings.-A housing which is proof against fire-damp or other gas and is adapted to contain electrical apparatus, comprises an underframe and a hood, projections on one of these parts being forced under counterpieces on the other part so that on rotation of one part with respect to the other, the parts are locked together to form a gas-proof housing. The underframe 11 supporting the apparatus 13 is covered bv a hood 14 formed with projections 15 which are inserted in slots 17 and rotated into a slot formed between counterpieces 16 on the underframe and the underframe itself. The inclined surfaces 19 on the counterpieces ensure a firm pressure between the parts, and a hinged bolt 20 is then moved into place to prevent movement of the hood 14 in the opening direction. A projection 22 on the connection plug 21 prevents access to the bolt when the plug is in place, and the bolt, by assuming a horizontal position when unfastened, prevents insertion of the plug.

Title: Improvements relating to the removal of metals from petroleum fractions
IPC: C10G29/04
Filed: 1960-10-10
Abstract: The metal content of petroleum fractions boiling above 250 DEG C is reduced by contacting a feedstock with active Raney nickel, iron, or cobalt.  The contaminants may be present as porphyrins, e.g. vanadyl or nickel porphyrines.  The contacting may be carried out at 0 DEG to 250 DEG C., and preferably at atmospheric pressure.  The ratio of Raney metal to petroleum is preferably 1:1 to 100:1 and the contact time is preferably 10 minutes to 100 hours.  The petroleum fraction may be dissolved in a lower boiling hydrocarbon solvent, for example benzene.  The Raney metal may be freed of the contaminants by means of solvents, e.g. petroleum hydrocarbons boiling below 250 DEG C., phenol, furfural, pyridine or butyrolactone, or by contacting with a saturated or unsaturated sulphur-containing organic compound or an alkyl hydroperoxide. The sulphur and nitrogen content of the petroleum feedstocks is also reduced by the above process.

Title: Improvements in or relating to control and stabilizing apparatus for aircraft
Inventor: BAUGER LOUIS JULES
IPC: B64C9/38
Filed: 1961-09-27
Abstract: 973,284. Jet reaction controlled aircraft. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Sept. 27, 1961 [Sept. 27, 1960], No. 34646/61. Heading B7G. [Also in Division F1] An aircraft comprises a pair of nozzles disposed so as to set up control moments by jet reaction, means for supplying each nozzle with compressed air at a constant rate, and means for separately heating the air supplied to each nozzle just upstream thereof, the moments being produced by heating the air supplied to one nozzle only, or by heating the air supplied to the two nozzles to different degrees. In the Figure, a fairing 4 or 6 at each wing tip encloses a forwardly, a rearwardly, and a downwardly discharging combustion chamber 8, 9 and 11, or 9<SP>1</SP>, 81, and 13, respectively. Downwardly discharging combustion chambers 15 and 17 are located at the nose and tail, respectively. Compressed air is fed to all the chambers from the jet propulsion engine compressor tap manifold 24, through master valves 5 which are open when the system is operative during take-off and landing. These valves may be butterfly valves, each having an aperture so that when a valve is shut off, sufficient air may flow to maintain a pilot flame in each combustion chamber. The fuel injector of each chamber is fed from two lines, lines 54, 55, 56, and 57 conveying sufficient fuel from a distributer 30 to maintain the pilot flame at all times. If no pilot flames are used, each chamber may be capable of ignition independently of the others. Fuel lines 50 and 51 feed power fuel supply to chambers 15 and 17, and are used to set up pitching moments either by having one chamber in pilot operation, and the other in power operation, or by having both chambers in power operation, but varying their fuel supply differentially. Similarly, roll control is obtained by controlling the fuel supply in lines 48 and 49, to chambers 11 and 13. Lines 52 and 52<SP>1</SP> supply chambers 7 and 7<SP>1</SP> equally, and lines 53 and 53<SP>1</SP> supply chambers 9 and 9<SP>1</SP> equally, but differential variations between the fuel flows to the pairs of chambers can be made for yaw control. Preferably, the injection of a power fuel supply to a chamber does not affect or decreases, its consumption of air from the compressor of the power plant, which may be used for direct lift during take-off or landing. Cross-coupling may be provided between the control systems so that, for example, pitching moments produced by the roll control system are cancelled out. The aircraft may be designed to take-off with its fuselage horizontal or vertical. Specification 750,601 is referred to.

Patent GB-920246-A (GB)
Title: A process for the isolation of synthetic monocarboxylic acids
IPC: C07C51/14
Filed: 1961-09-27
Abstract: Synthetic monocarboxylic acids, produced by the reaction of carbon monoxide and water with olefins or with paraffins in the presence of hydrogen acceptors, are separated from admixture with hydrocarbons and recovered by the steps of continuous countercurrent extraction with more than the equivalent amount of aqueous ammonia in the presence of a water immiscible organic liquid, separating the aqueous phase containing the ammonium salts of said acids and subjecting the aqueous phase to continuous distillation whereby free and bound ammonia are removed and the acids are recovered.  The excess ammonia employed may be greater than 20%, preferably 50-90% of the equivalent amount; for isolating acids with more than 14 carbon atoms per molecule more than 100% excess may be used.  The extraction of such acids may be performed in the presence of a C1 to C3 alcohol e.g. methanol, ethanol, isopropanol.  The continuous phase may be either the organic or the aqueous phase; the water immiscible organic liquid preferred is an aromatic free or deficient gasoline fraction having preferably a boiling point below that of the hydrocarbons admixed with the acids, in order that the above liquid may readily be separated from the hydrocarbons by distillation.  Preferably extraction is effected in a rotary disc contractor column as described in Specification 659,241.  More than one extraction unit in series may be employed.  The separated aqueous phase is continuously fed through an evaporator, thus causing the ammonium salts to decompose and the ammonia to evaporate.  The acid may thereafter separate out as a distinct phase and be recovered and the aqueous residue returned for re-use.  Carboxylic acids derived from hydrocarbons containing more than 12 C atoms readily form emulsions when a greater part of the ammonia has been removed.  This is overcome by evaporating all the volatile matter simultaneously; the recovered ammonia and aqueous liquids are recycled.  The starting materials may be the mixture of hydrocarbons and acids obtained by the reaction of carbon monoxide with olefins in the presence of complexes of phosphoric acid, boron trifluoride and water.  The drawing (not shown) gives a flow diagram of a fully integrated plant incorporating a rotating disc contractor and provision for recirculating ammonia, aqueous ammonia and the immiscible organic liquid, and includes stills for distilling the purified acids and separating the unreacted hydrocarbons extracted by the organic extractant.  Examples 1 and 2 relate to the recovery of acids derived from C8-C10 olefins and include an outline of their synthesis using phosphoric acid/boron trifluoride/water catalyst while Example 3 relates to those obtained by the carbonylation of C14-C18 olefins and includes the presence of methanol in the ammonium salt decomposition stage.

Title: Improvements in the manufacture and production of hydrogen or gas mixtures containing the same
IPC: C10J3/00
Filed: 1929-11-18
Abstract: Hydrogen or a mixture thereof with other gases, such as carbon monoxide, is obtained by treating hydrocarbons, or materials containing the same, with air or oxygen in a chamber substantially free from carbonaceous matter, to produce complete or substantially complete oxidation, the resulting gases being then caused to act on heated carbonaceous materials such as coal or coke.  Combustion of the hydrocarbons is effected in a chamber separate and distinct from the first chamber and excess of air or oxygen may be used, but less than the quantity theoretically necessary may be employed, the products of combustion being mainly water vapour and carbon dioxide with a little hydrogen and carbon monoxide.  The hot gases are conducted, together with additional water vapour, over hot coke &c., a mixture of hydrogen and carbon monoxide being formed, together with nitrogen when air is used in the first stage.  Catalytic conversion of the carbon monoxide to dioxide and absorption of the latter may be effected when desired and the mixture used for the synthesis of ammonia. Powdered coke may be employed instead of lump coke, it being injected by means of steam into the combustion gases.  Preferably material containing only small amounts of hydrocarbons, such as coke, or brown coal previously treated by low temperature carbonization, is employed in the second stage.  The hydrocarbons used in the first stage may include gaseous hydrocarbons, such as natural gas or methane separated from coke-oven gas, waste gases from destructive hydrogenation processes or from ammonia synthesis, liquid fuels and distillation residues.  Examples are given of the employment of industrial waste gases and of a mixture of liquid hydrocarbons. Specificatio 29367/10, [Class 55 (i), Coking &c.], is referred to.
