Title: Improvements in automatic fuel regulators
IPC: F02M7/12
Filed: 1921-12-31
Abstract: 173,528. Pognon, M. Dec. 81, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Spray carburettors.-The Specification appears to describe (1) a carburettor, Fig. 1. with means for regulating the fuel supply, and (2) means, Fig. 2, for controlling the air supply to a carburettor. As shown in Fig. 1, a fuel nozzle B opens into an air supply passage A and is supplied with fuel from a constant-level chamber through an annular passage O between the nozzle and a suction-actuated piston C. The constant fuel level is shown by the line E-E. The piston C rises at each suction stroke of the engine to an extent depending on the suction, and the amount of fuel supplied is controlled by the resistance offered by the varying length of the passage O, the amount being thus reduced at high speeds. Fuel may also be admitted to the interior of the piston C, discharge holes being provided in the top thereof. The piston C is connected by a rod F to a piston G working in a cylinder I provided with air admission holes controlled by a cap K. The piston G may be constructed so as to control the admission of secondary air to the passage A. The nozzle B and piston C may have different diameters at different parts of their length or may be conical, and an ordinary nozzle valve may be provided at the upper part of the nozzle. As shown in Fig. 2, the air supply passage A of a carburettor is provided with a cylinder H having air inlet holes therein controlled by a cap I and containing a piston G connected by a rod F to a cylindrical valve E controlling an air inlet. As the suction increases, the piston G rises, thus opening the valve E. When applied to aviation motons, the air admission beneath the piston G may be controlled through a pipe extending to a point adjacent the aviator, thus allowing the device to be regulated for altitude.

Title: Improvements in or relating to methods of separating mixed fatty acids
IPC: C11C1/00
Filed: 1946-11-28
Abstract: Animal fatty acids such as stearic, palmitic, and oleic are separated by chilling a solution thereof in an organic solvent to which a small amount of neutral fat has been added, whereby crystals of good filtering characteristics are formed.  The neutral fat content of the stock is adjusted to from 0.2 to 3.5 per cent based on the weight of the stock.  Preferably a water-miscible polar solvent such as methyl, ethyl or isopropyl alcohol, or acetone containing water not in excess of 15 per cent, is employed.  If the fatty acid stock should itself contain more than 3.5 per cent of fat, fatty acid free from neutral fat is added to reduce the free fat content to the stated limits. The concentration of the fatty acids in the solvent must not substantially exceed 30 per cent by weight.  This process is applicable to the fractionation of stearic and palmitic acids.  In an example, distilled fatty acids obtained from a blend of 90 per cent tallow and 10 per cent garbage grease are mixed with 0.25 per cent tallow and dissolved in methanol.  On cooling, a dry granular precipitate is obtained which settles quickly and yields a dry powdery cake on filtering.  The oleic acid remains in the solvent. Specification 632,583 is referred to.
