Title: A process of improving perfumes
IPC: C11B9/02
Filed: 1927-10-29
Abstract: 305,555. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 29, 1927. Essential oils, purifying.-Essential oils, and other substances used in making perfumes are submitted to partial hydrogenation whereby impurities are hydrogenated in preference to the substance themselves, subsidiary odours being destroyed. The hydrogenation may be produced in known manner by the action of hydrogen in presence of a nickel catalyst or by the action of sodium ethylate, aluminium amalgam, zinc dust or the like. The proportion of hydrogen or other reducing agent is generally so selected that hydrogenation ceases when the subsidiary odour due to the impurities has been removed but hydrogenation of a fraction of the substance it. self is not advantageous. Other perfumes and essential oils such as geraniol, eugenol, isoeugenol, citral, lemongrass oil, clove oil, East Indian sandal oil, vetiver oil, Bulgarian rose oil, olibarnum resin, labdanum extract, may be treated similarly.

Title: Cylindrical shaft bearings
IPC: F16C25/02
Filed: 1946-10-02
Abstract: 617,459. Bearings. HERBERT, Ltd., A., and EATOUGH, C. Oct. 2, 1946, No. 29332. [Class 12 (i)] A plain bearing for a rotary shaft, comprises a housing for a non-split bearing sleeve which will just take the shaft and which, while being substantially rigid, is compressible under relatively high pressures, the housing being adapted to compress the sleeve so that the clearance between the shaft and sleeve can be adjusted to a minimum. This bearing may be used for the piston-shaft of an air-operated chuck, compressed air for the chuck cylinder being fed along bores in the interior of the shaft from passages provided through the bearing, the compressed bearing sleeve limiting loss of air by leakage. The bearing sleeve, in order to have anti-friction properties should be formed of or incorporate bronze, brass, white metal, graphite or the like; it may be a lubricantcontaining sintered metal in which case it may include a substantial portion of iron powder. Alternatively, if the shaft itself is of bronze or other non-ferrous material, the sleeve may be mainly ferrous. A shaft 11 is journalled in a non-split sleeve 12, which has its external surface 13 tapered to co-act with the tapered internal surface of a housing 14, so that when the sleeve, placed on the shaft, is driven axially into the housing by a press or screwed end plates, it is compressed as required. alternatively the sleeve may be adjusted in the housing before it is placed on the shaft, which is then used as a gauge, The shaft 11 has two bores 17 along which compressed air can be selectively fed to opposite sides of the piston of an air-operated chuck, the supply pipe inlets 18 opening on to annular grooves 19 formed on the inner periphery of the bearing sleeve 12 and connected with the bores through radial passages 20. In a modification, Fig. 3 (not shown), the bearing sleeve has a cylindrical external periphery, the housing having a corresponding cylindrical bore and being slit radially so that it can be clamped round the sleeve to compress it.

Filed: 1945-11-05
Abstract: 603,918. Gas-turbine plant. MASCHINENFABRIK OERLIKON. Nov. 5, 1945, No. 29387. Convention date, Nov. 30, 1944. [Class 110 (iii)] [Also in Group XII] A combustion chamber for a gas turbine has a cooling jacket consisting of two co-axial chambers, the inner of which is, at one end, in communication with the flame space and with the outer chamber and which is provided at the end remote from the first-mentioned end with an inlet for the cooling air so that the cooling air cannot enter the flame space or the outer chamber until it has traversed the inner chamber. In a gas-turbine combustion chamber 1 provided with a cooling jacket consisting of two coaxial chambers 5, 6, the inner chamber 5 is first traversed by the cooling air in the direction opposite to the flow in the flame space 2. Part of the cooling air passes from the space 8 through the outer cooling chamber 6 to a space 9 where it mixes with the gases from the flame space 2 and part flows into the flame space and acts as air for combustion. The amount of air supplied for combustion can be regulated by a throttle member 11 formed as an adjustable guide blade ring which may be located in the combustion air supply, as shown, or in the cooling air supply to the chamber 6. The passages 5, 6 may be so designed, that under the design operating conditions, the amount of air flowing to the flame space is correct without the need for throttling by the member 11.

In a friction clutch having a driven plate engaged between a driving fly-wheel and a presser plate 11 by a diaphragm spring 12 formed with radial fingers 13, a thrust-ring 20 which co-operates with a release bearing (not shown) is mounted on the diaphragm spring by means of a sheetmetal carrier 23 having lugs 32 projecting between the fingers 13. A steel wire ring 33 is placed between the thrust-ring 20 and the fingers, and a split-ring 34 is placed between the fingers 13 and radially projecting portions 28 of the lugs 32 which are then bent inwardly so that the thrust-ring is retained on the fingers 13. The thrust ring 20 may be formed with notches 26 into which a flange 25 of the carrier 23 is deformed in order to lock it to the ring 20. Alternatively the notches 26 are dispensed with and the ring 26 is held in its carrier solely by friction.
