Title: A method of obtaining purified kauri-gum from crude kaurigum and apparatus therefor
IPC: C09F1/00
Filed: 1925-06-26
Abstract: 237,576. Buchan, N. July 23, 1924, [Convention date]. Resins.-Purified kauri gum containing essential oils is extracted from the crude gum by a solvent consisting of ethyl ether or ethyl ether and a volatile hydrocarbon such as benzene, and the solvent is separated from the extract by volatilization. The crude gum is agitated with the solvent in an extractor 1. Steam may be supplied for heating purposes by a pipe 19. The extract is allowed to settle and then run off through decanting valves 18 and a strainer 26 to a still 28, where the solvent is distilled off by a steam coil 29. Solvent vapour passes through pipe 34 to a water-cooled surface condenser 36, and thence the condensed solvent passes by pipe 39 to a water separator 40, and finally to a storage tank 49. The last traces of solvent in the still 28 are removed by a vacuum pump 56, through pipes 54 and 57 to the condenser. The gum is run off through a cock 32. Solvent is removed from the extractor 1 by admitting steam from the pipe 19, and passing the vapours through pipes 24 and 34 to the condenser. The refuse may be removed through a door 16.

Filed: 1952-07-07
Abstract: 718,657. Gasifying solid fuel. KOPPERS GES., H. July 7, 1952 [July 13, 1951], No. 17063/52. Class 55 (1)  In a process for the continuous generation of combustible gas from finely divided solid fuel, the fuel is suspended in oxygen and is injected from nozzles 13 into conical reaction chambers 9 and 10 which open tangentially into the upper part of a cylindrical vessel 1 provided with a cooling water jacket. The fuel is ignited near each nozzle and forms an exothermic reaction zone 16. Steam or carbon dioxide is admitted from an annu'ar nozzle 15 to form an envelope around each zone 16. The reactants travel in a straight path through chambers 9 and 10 and into vessel 1, the exothermic reaction being substantially complete before they impinge on the, vessel wall at 17. Due to their inertia and the effect of centrifugal force, the velocity of the highly heated, unburnt particles is 'greatly reduced as the reactants pass around the wall of the vessel, the resulting relative movement between the steam or carbon dioxide and the particles facilitating the endothermic reaction. The generated gas and the fuel residue discharge through water cooled outlets 6 and 8-respectively.

Abstract: 924,582. Particular-setting mechanisms; minimum fare adjustment. HALDEX A.B. May 11, 1961 [May 11, 1960], No. 17259/61. Classes 106 (1) and 106 (3). A counter which may be reset to a value capable of adjustment comprises adjustable numeral wheels each having a digit drum and driving gear coaxially mounted and relatively rotatable, the driving gear carrying a resetting heart cam and being locked in relation to the digit drum by axially movable releasable locking-pins. The arrangement is particularly suitable for adjusting the minimum fare in taximeters. A disc 9 fixed to the digit drum 1 is provided with ten circularly arranged holes 15 through two diametrically opposed ones of which project the end portions of two pins 13 axially movable in bores 12 in a bushing 5 attached to the hub 3 of the numeral wheel driving gear 2 which carries a resetting heartshaped cam 7. The pins 13 are maintained in engagement with the holes 15 by springs 14. To adjust the reset value, a two-pronged tool 17 is employed to depress the pins 13 against the action of the springs 14. The tool is then manually rotated thereby rotating also the digit drum 1 relative to the gear 2 until the pins 13 snap into the adjacent pair of holes 16. The reset value provided by the heart cam 7 is thus altered by one digit. The adjusting process may be repeated to alter the value by more than one digit.
