Title: Improvements in carburetters for internal-combustion engines
IPC: F02M17/44
Filed: 1927-11-17
Abstract: 297,377. Soc. du Carburateur ZÚnith. Sept. 20, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Spray carburettors. - The members for the production and circulation of an emulsion are located within the float chamber close to the vertical axis thereof; the mixture outlet tube is disposed obliquely to said axis; the emulsion supply conduit is vertical and substantially axial and opens into the mixture outlet tube below the float chamber and the fuel level remains substantially constant during tilting at a level just below the point where the emulsion enters the vertical tube. The float chamber is integral with the mixture outlet tube 2 which is inclined preferably at an angle of 45‹ to the axis of the float chamber approximately along which the emulsion tube 8 is situated. At the lower end of the mixture outlet tube is a swivelling air inlet conduit 3. The float chamber is closed by a, cover 14 and encloses a boss 5, Fig. 4, in which the emulsion conduits 8, 9, 10, 12 are formed. The conduit 12 connects the upper part of the float chamber with the air inlet conduit 3 and extends to such a height that fuel cannot overflow into it. Fuel flows through a conduit 16, Fig. 3, into the well 9 and emulsion enters the conduit 8 through a duct 18 just below which stands the constant fuel level maintained by a float consisting of a pair of cylindrical members 96, Fig. 4. The conduit 8 discharges into a Venturi 20, Fig. 2, having arms 21, 22 which bear against a second Venturi 25. The arm 21 is hollow to convey the emulsion, the arm 22 being solid and held by a spring-loaded plunger 30. In a modification the arm 22 bears on a cap enclosing the loading spring. A tube 45 is located in the well 9, Fig. 3, an annular space 46 being left between them and connected by a conduit 10 with the air space of the float chamber. Within the tube 46 is a tube 51 having a constriction 52 serving as a main nozzle. The tube 45 has calibrated holes 47 leading to space 46, and the tube 51 has a calibrated hole 53 leading to annular space 55 between the tubes 46, 51. The orifice 53 constitutes the compensating nozzle and emulsion passes to the duct 18 from annular space 55 and by way of orifices 56. The upper end of conduit 8, Fig. 3, may be closed, or provided with an ejector nozzle 68 open at 69 to the float chamber air space and serving by the flow of air therethrough to entrain and atomize the fuel from the duct 18. In a modification, Fig. 6, the nozzle 71 discharges into a small Venturi 70 and has an aperture 72 to prevent siphon action. In a further modification the nozzle terminates short of the Venturi so as to leave an annular space into which the duct 18 discharges. The fuel enters the float chamber at 80, Fig. 3, and is controlled by a needle valve 82 seating in and guided by a screwed-in member 81 with outlet apertures 83.

Title: Solid dosage units having an enteric coating of a partially esterified polyvinyl alcohol
IPC: A61K9/26
Filed: 1957-10-03
Abstract: Polyvinyl alcohol with a degree of polymerization of 600 to 800 is partially esterified with phthalic anhydride to produce a product with a phthalyl content of 60-70% by weight and an acetyl content of 1,6 to 6,0% by weight which, being substantially insoluble in the stomach juices but soluble in the intestinal fluids is used as an enteric coating for solid medicinal oral dosage units. Esterification is performed by refluxing in an inert solvent, e.g. pyridine. picoline or methyl ethyl ketone. The reaction mixture is forced into aqueous mineral acid to precipitate the product which is usually applied as a coating from a solution e.g. 95% ethanol.ALSO:A solid medicinal oral dosage unit consists of a core containing at least one medicinal agent coated with an enteric film of polyvinyl alcohol having a degree of polymerization of 600 to 800 partially esterified with phthalic anhydide.  The esteric coating has a phthalyl content of 60-70% by weight, an acetyl content of 1,6 to 6,0% by weight.  It is applied from a solution, e.g. in 95% ethanol, the solution being applied in several increments to build up a layer of desired thickness. Solvent is removed by a stream of warm air and the units are dusted, e.g. with talc between layers while the coating is sticky to prevent their sticking together.  In example I, tablets containing brewers yeast concentrate, thiamine hydrochloride, riboflavin, niaciamide, hyridoxine hydrochloride, vitam B12, vitamin C and vitamin D are coated with a film of polyvinyl alcohol acetate phtlalate (phthalyl content 65%, acetyl content 4,8%) applied as a 30% w/v solution in 90% denatured alcohol. Example II is similar using tablets which contain ferrous sulphate, edible bone flour, vitamin A acetate, vitam D, vitamin B1, riboflanin, niacinamide, vitamin C and roduim iodide.  In both examples a standard sugar coating was applied over the entire layer.
