Title: Improvements in carburetters for internal combustion engines
IPC: F02M9/127
Filed: 1920-07-09
Abstract: 148,158. Girin, A. June 17, 1919, [Convention date]. Spray carburettors.-In a spray-carburettor the air valve is controlled simultaneously with the fuel valve, the float maintains the level of the fuel constant even when the fuel tank is inciined, and the handle for the air valve is used to depress a plunger to flood the nozzle. The connexion between the control handle and the fuel valve is variable by adjusting the fulcrum of a lever in the linkage. As shown in Fig. 1, the handle is on the plate D and moves the air valve A<2> through the rods E, E<2>. A fuel valve C in the form of a tube with superposed needles is in nozzle B and is moved through the cam groove D<5>, lever H and linkage J, E. The fulcrum H<1> of the lever H is adjustable to compensate for aititude, temperature &c., and may be moved far enough to close the fuel valve and allow air only to be admitted for braking &c. The plate also acts on the plunger F<1> in a chamber connected to the fuel reservoir A<7>; if the handle is moved sharply, fuel is forced out of the nozzle B, the restricted orifice L<4> preventing return of the fuel to the float chamber. The float consists of two hemispheres in separate chambers, the hemispheres being connected by a rod which bears on the needle valve N. The float chambers are disposed centrally about a point in the fuel nozzle, so that tilting of the carburettor has no effect on the fuel level. A balance weight M<3> is used with the floats. The Specification as open to inspection under Sect. 91 (3) (a) describes also a fuel nozzle with a number of orifices which can be closed in sequence by pins on the adjustable valve C; or the nozzle opening may be a slit, which is more or less closed by a blade or fork on the valve. In another modification, the nozzle has a simple orifice, the fuel flow being controlled by a plate entering a slit, or by a tube l, Fig. 22 (Cancelled), which moves between two forks, these forks closing more or less slots m. connecting the fuel passage to the tube. This subject-matter does not appear in the Specification as accepted.

Patent GB-697506-A (GB)
Title: Preparation of dibasic carboxylic acids
IPC: C07C51/00
Filed: 1951-08-28
Abstract: Aliphatic dicarboxylic acids are prepared by treating with reducing agents the peroxides obtainable by the action of hydrogen peroxide on cyclic ketones R=C=O, R being a divalent radical of 3-9 carbon atoms (excluding substituents).  Suitable reducing agents are compounds of metals showing more than one valency (e.g. iron, cobalt, manganese, copper, chromium), ascorbic acid, sodium formaldehyde sulphoxylate, sodium bisulphite and reducing sugars.  Mixtures of such may be used, especially a ferrous salt with another reducing agent.  The reaction may be carried out in water or organic solvents at - 100 DEG  to + 100 DEG C., preferably in the absence of oxygen.  It is desirable to mix the reactants rapidly, e.g. by dissolving each separately in a common solvent before mixing.  The process may be carried out batchwise, semicontinuously or continuously, in the latter case by mixing the materials in a tubular reactor under conditions of turbulent flow. The dibasic acids can be isolated by distillation, ion-exchange or extraction, or by conversion into salts or esters. In an alternative process the alkyl ethers of the peroxides are reduced to give diesters of the acids, which can then be hydrolysed. Examples show the production of sebacic acid and dodecan-1 : 12-dioic acid from cyclopentanone peroxide and cyclohexanone peroxide respectively, reduction being carried out with ferrous sulphate, l-ascorbic acid and ferrous chloride.  In one case an emulsion of the peroxide, benzene, water, sodium lauryl sulphate and sodium dihydrogen phosphate is treated with a mixture of sodium formaldehyde sulphoxylate and ferrous sulphate; the acid is recovered from the benzene phase.  Many suitable radicals are specified for R in the above formula, which may be substituted with hydrocarbon radicals, chlorine, fluorine, hydroxyl, methoxyl, carboxylic acid, carboxylic ester or ketonic groups.  Peroxides suitable for the above process may be prepared by reacting cyclic ketones with hydrogen peroxide or by oxidizing cyclic secondary alcohols with molecular oxygen in the presence of a free radical initiator such as ultraviolet rays or an azonitrile.  In examples: (1) cyclopentanol is irradiated in the presence of oxygen, benzoin and calcium carbonate; (2) cyclohexanol is irradiated in oxygen.  The products are probably 1-hydroxy-11-hydroperoxy-dicycloalkyl peroxides though other possible formul  are given.  The alkyl ethers of peroxides mentioned above are obtained by treatment of alkyl ethers of cyclic secondary alcohols with oxygen, preferably in the presence of free radicals.

Filed: 1938-07-08
Abstract: 516,806. Centrifugal separators. BERGES, A. July 8, 1938, No. 20325. Convention date, July 10, 1937. [Class 23] Centrifugal apparatus for cleaning paper pulp has a stationary container 1 with a tangential entry nozzle 2 of rectangular cross section, and has a sheltered space below the disc 4 into which heavy impurities are drawn through the annular space 5. The long side of the nozzle section is parallel to the axis of the apparatus and the container 1 increases in diameter below the entry ; it then forms a cylindrical part with a depending hopper terminating in a discharge chamber 9 with valves 10, 11. An inner compartment of the separator has a wall 3 which is cylindrical in the upper part but has a diminishing diameter below the inlet. The disc 4 is supported by a central tube 6 connected to a pipe 7. The material is introduced through the inlet nozzle 2 and whirls in the part A of the container. The heavy impurities are thrown outwards and pass through the annular space 5 to the part B of the container. Their passage is assisted by the slight suction exerted on the chamber by the effect of the tube 6. The material with the light impurities passes to the inner compartment where the light impurities move inwards and are discharged through the pipe 18 and outlet 20. The clean pulp passes through the gap 21 outside the pipe 18 and enters the discharge pipe 22. Air or overflow material passes through the gap 23 to the outlet 24 above the inlet 2. Water is admitted from the pipe 13 to fill the discharge chamber 9 before the valve 10 is opened to admit separated solids. After the solids are in the chamber the valve 10 is closed and the valve 11 opened to discharge them. A pipe 17 is provided for the supply of dilution fluid to the apparatus. In a modification the separation is accomplished in two stages, the heavy impurities being separated in the first stage while the light impurities are separated in the second stage in a separate apparatus.
