Patent GB-438635-A (GB)
Title: Method and means for running carburettor internal combustion engines
IPC: F02M1/00
Filed: 1935-01-21
Abstract: 438,635. Spray carburetters. SVENSKA ACKUMULATOR AKTIEBOLAGET JUNGNER, 17, Riddaregatan, Stockholm. Jan. 21, 1935, No. 1966. Convention date, Jan. 22, 1934. [Class 7 (iii)] In producing fuel-air mixtures from separate supplies of light and heavy fuels, the composition of the mixture is varied so that when the exhaust gases are insufficiently hot to expel substantially completely from the lubricating oil fuel that has entered it as an impurity. the engine is supplied exclusively or essentially with light fuel whereas, when the gases are sufficiently hot to effect that expulsion the engine is supplied exclusively or essentially with heavy fuel and the fuel contained in the lubricating oil is expelled therefrom and returned to the fuel supply system. The change from one fuel to the other may be effected by a thermostat or by a predetermined vacuum in the induction pipe. Light and heavy fuels are fed from float chambers 33, 34 to a change over device 37 adapted in one position I to supply light fuel to a main nozzle 32 and to transition, idling and starting nozzles 40, 39, 41, in a second position II to supply the main nozzle with heavy fuel and the other nozzles with light, and in a third setting III to continue the heavy fuel supply to the main nozzle but to cut off both fuels from the other nozzles. In the second position, the disposition of the nozzles ensures a gradual change over from one fuel to the other as described in Specification 413,155. Included in the lubricating oil system is an exhaust heated rectifier 51, Fig. 4, into which oil is pumped through an inlet 63 and accumulates until a float operated lever 54 lifts the stem 68 of a valve 67 to admit air and permit oil to drain away past a valve 58 connected to the lever 54. The fuel oil vapours are transmitted through an outlet 65 to the induction pipe.

Patent GB-1459161-A (GB)
Title: Rotary-vane pump
IPC: B62D5/07
Filed: 1975-01-17
Abstract: 1459161 Rotary Vane Pumps ZAHNRADFABRIK FRIEDRICHSHAFEN AG 17 Jan 1975 [17 Jan 1974] 2088/75 Heading F1F To control the discharge characteristics over a range of speeds, a rotary vane pump has a cylindrical insert 16 disposed transversely in a passage 13 leading to a by-pass valve 14 from a discharge chamber 10. Pump discharge is through a port 17 in the insert 16 to a line 20 and via another throttle (not shown) a reduced pressure is transmitted through a line 19 to the downstream side of by-pass valve 14. The angular orientation of the port 17 relative to the flow of fluid into the passage section throttled by the insert 16 determines the static pressure at which fluid is discharged through port 17 because the throttling effect of the insert 16 results in differing pressure fields across it and thus determines the pressure difference across the valve 14.
Patent GB-297724-A (GB)
Title: Improvements in the clouding of enamels
IPC: C03C4/00
Filed: 1928-01-23
Abstract: 297,724. Kreidl, I. Sept. 26, 1927. [Convention date]. Enamels are adapted to be clouded by the production in the mass of finely distributed bubbles of gas evolved during the firing of the enamel from organic substances or substances containing volatile organic components, which are added to the batch in the enamel mill. The evolution of gas may be brought about by the chemical interaction of two or more substances, at least one of which is of organic type. An oxidizing agent such as saltpetre may be added to the clouding medium or the enamel batch so as to prevent discolouration and also to promote the liberation of gas from the organic clouding medium. Organic clouding materials such as formic acid and its salts, benzoic acid and its salts, oxalic acid and its salts, acetic acid and its salts, naphthol, benzidine, starch and flour may be used, such substances being employed, if necessary, with one or more substances, which promote their volatilization. Organic-inorganic substances such as calcium formate, calcium acetate, sodium acetate, ammonium oxalate, &c. are also mentioned. The viscosity of the enamel, and therefore the permeability of the enamel to the gas bubbles, may be varied by regulating the amounts of fluorides added to the mass. The Specification as open to inspection under Sect. 91 (3) (a) also describes the use of carbon and carbides as clouding media, and states that the invention is applicable to the clouding of glasses. This subject-matter does not appear in the Specification as accepted.

Abstract: 1383432 Circulation in defined paths L A A LEFRANCOIS 17 Jan 1972 [20 Jan 1971] 2156/72 Heading B1C [Also in Division C6] In the propagation of micro-organisms and production of substances by fermentation in apparatus consisting essentially of an ascending head, a descending head and provision for agitating the liquid medium by insufflating a stream of gas into the lower portion of the ascending head chamber, the ascending head chamber has a lower portion 1, Fig. 1 of restricted cross-sectional area and an upper portion 2 which increases regularly in width. The apparatus may be employed for aerobically propagating yeast on neutralized desulphitized bisulphite liquor from a paper pulp mill. The enclosed apparatus of Fig. 5 is suitable for an ethanolic fermentation by yeast wherein the. requisite agitation is achieved by re-injecting part of the carbon dioxide produced into the lower portion of the ascending head chamber 17 through line 22. Apparatus of the form depicted in Fig. 3, in which the chambers are disposed externally of each other, may, for example, be used for growing yeast on normal paraffins. The following preferred features are disclosed: The orifices through which the insufflation gas is introduced are 1 sq. inch in cross-section with a spacing of the order of 4 inches (10 cm.). The rate of penetration of the insufflation gas into the liquid medium ranges from 10 to 40 metres/sec. A centripetal accelerator may assist the insufflation of gas. The cross-sectional area of the ascending head chamber at the top. is up to 5 or 6 times larger than at the bottom. The rate of flow of liquid medium at the end of the ascending head and through the descending head is kept at a value higher than 0.2-0.5 metres/sec. The volume of the chambers may be reduced by the interpositioning of solid bodies, see 25 on Fig. 3. The liquid medium may make roughly 1-3 revolutions of the apparatus per minute. The temperature of the liquid medium is regulated by use of hollow partitions within which cold water is circulated, see Fig. 7 on Fig. 2 and 15 on Fig. 4. These may bear on the bottom of the apparatus to strengthen the structure. The number of ascending head chamber(s) in the apparatus may differ from the number of descending head chamber(s).

Patent GB-763625-A (GB)
Title: Improvements in or relating to the purification of hydrocarbons
IPC: C10G25/00
Filed: 1954-01-28
Abstract: The mercaptan content of a hydrocarbon distillate, for example a gasoline, is reduced by leading the distillate through at least one column containing a layer of active carbon impregnated with an aqueous alkaline liquor and the used impregnated active carbon is subsequently regenerated by means of an oxygen-containing gas in the absence of steam.  According to a modification of the process, the regeneration of the active carbon, instead of being effected subsequently, is effected continuously during the passage of the distillate through the column by adding air to the hydrocarbon distillate, either in the column or before the column.  The alkaline liquor may be an aqueous solution of an alkali metal hydroxide, particularly sodium hydroxide, or of ammonium hydroxide, and the oxygen-containing gas may be air of oxygen.  The alkaline liquor may contain organic or inorganic activators and a list of substances suitable for this purpose is given.  Mercaptans in the hydrocarbon distillate are converted, by contact with the active carbon, to disulphides which remain dissolved in the distillate.  The active carbon becomes contaminated with mercaptides and the regeneration with oxygen-containing gas effects removal of the mercaptides.  The active carbon in time may become contaminated with phenolates and regeneration by steaming is then necessary.  The hydrocarbon distillate, before contact with the active carbon, may be freed of hydrogen sulphide, for example by washing with aqueous sodium hydroxide solution, followed by water-washing and drying in a coalescer containing iron filings.  In the examples, gasoline is sweetened by contact with active carbon impregnated with aqueous sodium or potassium hydroxide, air being introduced with the gasoline or used subsequently to regenerate the active carbon. Activators mentioned in the examples are methanol, glycol, dimethylamine, hydrochloride, diethanolamine, butyric acid, naphthenic acids, tartaric acid, acetaldehyde, acetone, grape sugar, phenol, m-cresol, petroleum phenols, alpha-naphthol, pyrocatechol, resorcinol, hydroquinone, pyrogallol, salicylic acid, resorcylic acid, gallic acid, tannin, p - aminophenol, N - benzyl - p - aminophenol, p - aminosalicylic acid, anthraquinone, alizarin, quinizarin, sodium salt of m - nitrobenzene sulphonic acid, picric acid, pyridine, hydrazine hydrate, hydroxides or sulphides of copper, ferric iron, chromium, manganese, lead, cobalt or nickel (formed in situ by the addition of a water-soluble salt of the metal and reaction between the salt and the alkaline liquor or sodium sulphide contained therein) and a mixture of ferric chloride and sodium potassium tartrate. Apparatus is described wherein the process employing air introduced with the hydrocarbon distillate is carried out in four towers, three being used in series and the fourth being out of action for steaming.
