Title: Improvements in or relating to internally-meshing gear pumps
IPC: F04C2/10
Filed: 1964-09-04
Abstract: 1,074,371. Rotary pumps. O. ECKERLE. Sept. 4, 1964, No. 36356/64. Heading F1F. In a rotary pump of the internally-meshing gear type, formation of air pockets in a chamber 14 containing a filter 12 is prevented by situating the inlet end 21 of a suction passage 20 in the uppermost region of the chamber, said passage being defined by a plate 19 attached to a cover plate 5 for the pumping gears 2, 3 and having its lowermost end connected to the low-pressure side of the gears by a passage 24 in the plate 5. The chamber 14 is formed by a screw-cap 13, which may be made of transparent material, and receives liquid e. g. fuel oil, through a bore (18), Fig. 4 (not shown), and either one of two inlet passages (22, 23), Fig. 2 (not shown), in a casing 10. The internally-toothed gear is pressed against the plate 5 by the pressure of liquid in a chamber 30 that is connected to a chamber 26 containing a pressure-control valve 27, the liquid leaving the high-pressure side of the gears being directed through a passage 25 and the chamber 26 to an outlet (28) at one end thereof. Surplus liquid in the chamber 26 escapes through either a passage (31) and a bore (32) connected to a reservoir (not shown in the drawings) or a bore (33) communicating with the chamber 14, the latter bore being otherwise closed by a stopper (34). The bore (33) is employed when the reservoir is situated at a level higher than that of the pump. The chamber 30 may be connected to an air-control valve (not shown in the drawings) through a connector 38, said valve being associated with an air blower for fuel combustion purposes.

Title: Process for the separation of organic compounds
IPC: B01D53/02
Filed: 1957-11-22
Abstract: <PICT:0871496/III/1> Mixtures of organic compounds are separated by extraction in two zones A, B in which an eluent gas flows upwards through column A and the product is withdrawn at the top 2, a part is fed into the bottom of column B and rises through it and is withdrawn at the top; at the same time a solvent liquid flows in counter current with the eluent gas down through column B and then through column A and is withdrawn at the bottom.  The rates of flow of gas and solvent and/or the temperature are different in each column and are so controlled that at least one component is carried down through column B and is withdrawn with the eluent gas from the top of column A.  As eluent gas there may be used air, hydrogen, nitrogen, methane, carbon monoxide, carbon dioxide or steam; and as solvent liquid, liquid hydrocarbons, ketones, esters, nitriles, ethers, silicones, glycols or glycerine.  The process may be applied to the separation of azeotropic mixtures, e.g. alcohol and water, essential oils, hydrocarbons, e.g. petroleum ethers and mixtures of benzene and heptane.  The mixture may be introduced into zone B.  The process may also be used to monitor chemical processes using the treatment described as a chromatographic column separation of products.  The two zones are packed with an inert solid material to provide a large surface area to the counterflowing media.  In the drawing, extraction zones A and B are shown as separate columns, but these may be combined with a single column.  The letters A and B correspond to the zones B and A above, the zone A shown having a hot section SH and a cool section SC.  The eluent gas enters a line B and flows upwards, a part being withdrawn (with extracted component(s)) through a line 5, and the rest passes to the bottom of zone A and is withdrawn through a line 4.  Solvent liquid introduced into a line 6 flows downwards through the cool and then hot sections of zone A and then downwards through zone B.  The mixture to be separated is fed into a line 8. If this comprises components C1 C2, C1 slowly ascends zone A and is drawn off with the eluent gas.  The flow rates and temperatures are adjusted so that C2 descends the column, and enters column B the temperature of which is constant and is sufficiently high to remove C2 in the eluent gas and the extract is withdrawn at line 5.  In examples a mixture of n-pentane and isopentane is separated into components using air and kerosene.  Specifications 871,491, 871,492, 871,493, 871,494 and 871,495 are referred to.

Leaf, shredded or, according to the Provisional Specification, puffed tobacco 7 is moistened in a rotary barrel 4 and has added thereto in a preferably internally-tined rotary barrel 11 tobacco powder which to increase its adherence to the tobacco has mixed therewith an adhesive derived from tobacco. The tobacco powder is derived from tobacco delivered by a weighing conveyer 15 to a drying cylinder 17 and thence via a conveyer 18 to a mill 19 which delivers the resulting small pieces to a fluid energy mill 22 also receiving adhesive in the form of coarse powder via hoppers 24, 26 and a vibratory conveyer 25, the mixture being comminuted in the mill 22 by air jets to a powder of the order of 1 to 76 microns particle size. Alternatively, adhesive dissolved in water may be added to the moistening water spray tank 37 via metering device 36, or adhesive comminuted in a ball mill may be added by a vibratory conveyer 34 directly to the barrel 11, and, in a modification, with either of these alternatives, the tobacco powder is formed by comminution in a ball mill and is added by a vibratory conveyer directly to the barrel 11. Reference is made to delivering a mixture of tobacco powder and adhesive to the tobacco in the hopper of a cigarette-making or tobacco-cutting machine and to rolling cigars in mixture or treating their binder leaves with mixture. The adhesive may be dissolved out of waste tobacco by steeping it in warm water, the solution being evaporated or freeze dried to separate the adhesive, possibly after pigments or nicotine have been dissolved out of the solution. The water from a stemcrushing machine may also be used as liquid adhesive. Specifications 817,832 and 827,011 are referred to.

Title: A process for the manufacture of practically dry carbon
IPC: C09C1/54
Filed: 1929-12-10
Abstract: Carbon black, produced by the decomposition of liquid hydrocarbons by the electric arc, is freed from contaminating liquid hydrocarbons by heat furnished by the combustion of the gaseous mixture formed at the same time, unsaturated hydrocarbons having been previously removed. The liquid hydrocarbons so driven off may be condensed and returned for decomposition.  Other combustible gases, such as coke-oven gas or water gas, may be mixed with the gases formed during the decomposition by the arc and, after any valuable constituents have been removed, may be utilized as the heating gases.  The Provisional Specification describes also the use of the combustible gases, in conjunction with the arc or alone, for the decomposition of the liquid hydrocarbons.
