Title: Adsorption of metal salts on neutral polymeric adsorbents
Inventor: KENNEDY JOHN
IPC: B01D15/08
Filed: 1954-05-17
Abstract: Polymers of triallyl, diallyl ethyl or diallyl methyl phosphates are prepared by bulk polymerization of the purified monomer in the presence of dibenzoyl peroxide in a sealed vessel in a water bath at 100 DEG  C.  A brittle transparent solid results after 10 to 20 minutes induction period after which the polymer may be further heated, ground and refluxed with acetone until the filtrate from the polymer is free from the monomer and low molecular weight polymers. The polymer may be dried in air and then over phosphorous pentoxide.ALSO:Tri-allyl phosphate is prepared by adding phosphorus oxychloride to a mixture of dry allyl alcohol, benzene and tri-ethylamine at a temperature of - 30 DEG  C. whilst stirring.  The temperature is allowed to rise to 0 DEG  C. and the reaction mass is filtered and dried and the benzene removed at low pressure.  The crude product is then fractionally distilled at low presure in the presence of a hydroquinone inhibitor and sodium carbonate to take up any acid formed through pyrolysis.  Diallyl ethyl phosphate and diallyl methyl phosphates may be prepared by the slow addition of ethyl or methyl dichloro-phosphates to allyl alcohol and triethylamine in benzene at 0 DEG  C.ALSO:Metal salts, particularly uranyl, lithium, ferric or cobaltous, are adsorbed from ketonic or alcoholic solvents by bringing the solution into contact with a polymer derived from a compound of the formula <FORM:0779739/III/1> wherein R1 is allyl, R2 and R3 are allyl o alkyl, there being no negative subtituent in the allyl chain, thereby adsorbing the salt on the polymer and subsequently recovering the salt by elution with an aqueous organic solvent or a neutral phosphoric acid ester.  The preferred polymer is one derived from tri-allyl phosphate.  Preferred organic solvents are acetone, methyl alcohol and ethyl alcohol whilst the preferred phosphoric acid esters for elution of the adsorbed salt are tri-alkyl phosphates such as tri-allyl phosphate, tri-butyl phosphate, di-allyl-ethyl phosphate and diallylmethyl phosphate. According to an example a solution of uranyl nitrate in acetone was passed through a column of poly tri-allyl phosphate and the adsorbed uranyl nitrate was subsequently removed by elution with acetone containing 30 per cent of water.  Further elution was effected with tri-butyl phosphate alone or in alcoholic or acetone solution.  The adsorption capacity of tri-allyl phosphate polymer for uranyl nitrate hexahydrate, cobaltous nitrate hexahydrate, and lithium chloride in acetone solution is given.

Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M19/03
Filed: 1932-05-20
Abstract: 401,742. Spray carburetters. NUGENT, P. R., Lad Lane, Dublin. May 20, 1932, No. 14382. [Class 7 (iii).] In a carburetter having main and pilot nozzles both of which slide into bores in the carburetter casing, the nozzle members are of different diameters to ensure that neither will fit into the bore of the other. Bores 4, Fig. 1, of dissimilar size, are formed side by side in the web 3 connecting the float chamber 1 with the induction tube 2, and jets or nozzle members 7, 20 are made sliding fits therein. Fuel, normally at a level L in the float chamber 1 flows through an outlet 6 to the bore 4 for the main nozzle member 7, which is of dumbbell shape, and through a recess in the lower portion 8 thereof to an orifice 12 in the waist portion. Here it mixes, in the bore 4, with ai'r drawn through orifices 13 from a recess in the upper end 7<1> of the nozzle member and the mixture is sucked through a passage 9 and slot 18 into the induction tube 2 by air drawn through the throat of the tube. At starting or during idling, the fuel leaves the chamber 1 by an outlet 21 at a higher level than the outlet 6 and flows through an orifice 23, Fig. 5, in the waist portion of the pilot nozzle 20 to a duct 24 therein which communicates with the atmosphere by an orifice controlled by a screw 25. Fuel flows to a reservoir passage 26 from which it is drawn through a siphon-like duct to an inlet so disposed in the induction tube as to be covered, by a projection 29 on the throttle 16 when the throttle is closed but to be uncovered on slight opening thereof at which position, the suction in the throat of the induction tube is insufficient to induce a flow of fuel through the main nozzle 7. A small drain duct is provided in the induction tube adjacent the throttle valve 16. Specification 157,528, [Class 7 (iii), Internal-combustion engines, Carburetting-apparatus &c. for], is referred to.
Patent GB-277088-A (GB)
Title: Improvements in or relating to automatic combustion control
IPC: F23N1/00
Filed: 1926-06-08
Abstract: 277,088. British Arca Regulators, Ltd., and Lindsay, T. June 8, 1926. Electrically controlling fuel supplies. -The fuel feed to the furnaces of steam-generators is controlled by the difference in the pressures due to the rate of flow on the opposite sides of a resistance interposed in the path of the generated steam by causing the pressure difference to act upon a relay of the kind in which the pressure of incompressible fluid issuing through a discharge aperture is varied by a displaceable checking member against which the jet impinges, this relay acting upon a pilot valve controlling a servomotor which regulates the fuel feed. Pitot tubes 9, 10 on opposite sides of an apertured diaphragm 8 in the main steam pipe C are connected by flexible pipes to the arms of a U-tube 28 pivoted at 31 and having enlargements 29. 30 containing mercury. One leg of the balanced U-tube is connected by a pin 37 with the pivoted checking lever 32 of the relay D which is similar to that described in Specification 116,074*. [Class 135, Valves &c.]. The other end of the lever 32 carries the checking member 12 upon which impinges a jet of water from a nozzle 11 supplied through a pipe 25 from a pilot valve E of the kind described in Specification 197,682, [Class 135, Valves &c.]. On decrease of flow in the steam-pipe C the U-tube is rocked against a spring 39 rocking the lever 32 against a spring 40 and moving the checking member 12 further away from the jet. This lowers the pressure in a chamber 24 of the pilot valve E and allows a spring 16 to move a diaphragm 15 and with it a slide 14 towards the left allowing fluid to pass from the cylinder 1 of a servomotor B through a pipe 7 to a chamber 17 and an outlet pipe 23. The piston 2 of the servo-motor therefore rises under the influence of a counterweight 6 thus rotating by a chain or rope 4 a rheostat A to lower the speed of a motor driving a pump or other means for feeding the fuel. Pressure fluid is supplied to the pilot valve E by a pipe 22 and passes through a bore hole provided in the slide 14, throttled by a pin 26, to the chamber 24 of the valve, a filter 27 being arranged to move with the slide. The liquid from the jet 11 after impinging on the checking member 12 escapes through a pipe 25<1>. 'To prevent over-regulation a spring 41 connected to the servo-motor piston 2 acts upon the checking lever 32 so as to restrict the movements of the piston. The load of the spring 41 may be varied by a turn-buckle 42. Means may be provided for altering the leverage of the limb of the' U-tube linked to the checking lever 32 or altering the size of the enlargements 29, 30. To maintain any desired pressure in the boiler independent of the rate of flow of the steam a pipe 46 connects the high pressure side of the diaphragm 8 with the outer side of corrugated bellows 43 arranged in a chamber 44 and connected by a pin 45 with the checking lever 32.
