Abstract: 1502285 Production of 4-monohalo-2-pyrazolin-5-ones AGFA-GEVAERT 2 Dec 1975 [11 Dec 1974] 53616/74 Headings C2C and C2P 4 - Monohalo - 2 - pyrazolin - 5 - ones are prepared by the reaction of a tertiary organic phosphite with a 4,4-dihalo-2-pyrazolin-5-one and subsequent hydrolysis of the 4-monohalopyrazole-5-enol phosphate ester formed. The process is particularly suitable for producing products of the general formula in which X is halogen, R<SP>1</SP> is optionally substituted C 1-20  alkyl, optionally substituted aryl, or optionally substituted 5- or 6-membered heterocycle and R<SP>2</SP> is optionally substituted C 1-20  alkyl, C 1-20  alkoxy, amino or substituted amino groups. The reaction is preferably conducted at 10-80 C. in an inert solvent such as benzene or acetonitrile using a trialkyl phosphite such as triethyl phosphite. Amongst the examples the compound 1-phenyl-3-(4-chloroanilino) - 4 - chloro - 2 - pyrazolin - 5 - one is prepared. 1 - Phenyl - 3 - (4 - chloroanilino) - 4 - chloro - 5- diethoxy phosphate pyrazole is prepared by reaction of triethyl phosphite and 1-phenyl-3- (4-chloroanilino)-4,4-dichloro-2-pyrazolin-5-one.

Abstract: 1,133,729. Mixing fibres. G. SHAW and C. H. ANDERSON. 20 Dec., 1965 [29 Dec., 1964], No. 53870/65. Heading D1F. Dissimilar types of fibres (e.g. having different colour, size, shape, or chemical composition) are mixed by supporting a bundle of such fibres at one end in a loosely confined and generally vertical position and displacing at least some of the fibres by forces acting at right angles to the axes of the fibres. The product may be used in making a brush having multicoloured bristles. As shown bundles containing dissimilar fibres can be mounted in bins A, B, C made up of collapsible members. The bins are mounted on a table 46 which can be reciprocated simultaneously in the direction of rails 126 and at right angles to this direction, the resulting motion being elliptical. Pins 38 on a base 36 are brought amongst the fibres and held stationary while the bins gyrate thus the fibres are mixed. A reciprocating or other motion of the bins is possible. The bins may be maintained stationary and the mixing pins moved.

Abstract: 1,273,140. Fuel injection pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct. 30, 1969 [Nov. 15, 1968], No.54304/68. Heading F1A. In a rotary distributer fuel injection pump valves 130 and 131 respectively are provided in the delivery passage 109 and each of the outlet ports 110 so that pressure waves arising from the closing of the injection nozzle valve do not affect the fuel pressure in the distributer. Valve 130 comprises a valve body 138 in a stepped bore between the delivery passage and an axial bore 108 connected to the pumping chamber 103, pumped fuel displaces the valve body against a spring 139 and thus passes via the passage 109 into the outlet 110. The valve 131 comprises a valve body 135 spring-loaded in a barrel 134 mounted in an adapter 132, the body having an annular groove 137 communicating via an internal bore with the outlet passage 110. Fuel axially displaces the body 135 until the groove 137 clears the end of the barrel whereupon fuel passes to the injection nozzle. At the end of the pumping stroke and whilst the passage 109 and port 110 are still in register the valves close, valve 130 closing first because of its smaller displacement. Fuel between the valves is slightly pressurized when valve 131 closes. Fuel is supplied to the pumping chamber from a feed pump 101 via a throttle and a shuttle measuring cylinder.

Filed: 1972-11-27
Abstract: 1407064 Sulphating cellulose ethers JOHNSON & JOHNSON 27 Nov 1972 [7 March 1972] 54669/72 Heading C3A Cellulose ethers may be sulphated by mixing them with an alkali metal or alkaline earth metal salt of a sulphating agent in a fatty acid reaction medium. The sulphated ether is recovered by adding water containing a quantity of base sufficient to maintain the pH of the solution at at least 3À8, The cationic strength of the mother liquor must be at least the value given by the relationship where C<SP>+</SP> is the cation concentration in gram equivalents per litre and D.S is the number of sulphate groups introduced per anhydroglucose unit. If unsufficient base is present to maintain the cation concentration at this level then salts may be added. The precipitated alkali cellulose ether sulphate is freed from w-precipitated salts, either by dialysis or by washing with water at above 80‹ C., or by washing with an aqueous solution having an alkali metal or alkaline earth metal salt concentration of between 0À9 and 2À5% by weight. The process is illustrated by the preparation of sodium ethyl cellulose sulphate.

An automatic force or weighing balance comprises a motor driven friction gear adapted to adjust the position of a rider weight of the balance, one member 6 of the gear being in frictional contact with a second member 21 which is longitudinally displaceable with respect to the member 6 in proportion to the applied force or weight, the second member being mounted on an articulated lever mechanism 11, 14 and being linearly displaceable. The member 6 consists of a roller mounted on a balance beam 1 and continuously rotated, during the measuring of a force or weighing of a load applied at 5, by a motor 8. The levers 11, 14 are provided with counterweights 12, 17 which are adjusted so that the centre of gravity of the lever system lies on the axle 10 of the lever 11. The member 21, which comprises a friction wheel provided with an arm 22 having a roller 24 adapted to run on a guide rail 25, is mounted on an axle 16 so that when the beam 1 tilts due to the application of a load at 5, the relative pivoting between the members 6 and 21 causes the roller 6 to longitudinally displace the wheel 21 until the balance condition is restored. Modifications are described in which the wheel 21 engages the upper surface of the roller 6 and the levers lie in a plane inclined to the vertical and in which the roller 24 engages the lower side of the guide rail 25.

Abstract: 1381200 Non-woven tape; spreading filamentary strands PHILCO-FORD CORP 8 Dec 1972 [8 Dec 1971] 56898/72 Headings D1F and D1R A tow of filamentary material is formed into a tape of parallel continuous filaments by spreading and partially aligning the individual filaments e.g. by passage of the tow through a slot venturi through which air flows in the same direction thereas, and then passing the spread tow through a (second) slot, venturi having coextensive spaced parallel plates disposed on opposite sides thereof and extending upstream and downstream, between which plates and through the slot air flows counter to the direction of tow movement. The filaments are thus fully aligned so as to form smooth tape free from gaps or angular overlay of filaments. In the operation of the machine represented wherein two or more tapes are formed simultaneously and then combined into a single sheet and stored, graphite filament bundles 10, 11, 12, 13 drawn by rollers 14 from supply spools 15 pass successively through a first slot venturi or preblower 18 to form spread tows 10a, 11a, 12a, 13a and a second 10b, 11b, 12b, 13b. Spreaders 18, 19, comprise or final slot venturi spreader 19 to form tapes several venturi devices in modular array, Fig. 2 (not shown) through which the tows may effect repeated passes. The output tapes 10b-13b are combined in side-by-side coplanar relation by passage through a device 20 to form a single sheet or tape T which passes over an idler roll 21 and is fed to a roller 22 submerged in a bath of impregnating material e.g. a plastics resin of the epoxy, phenolic or polyamide type. Tape T, subject to the tractive pull of rollers 16, 17 is joined to a carrier tape 24 e.g. of parchment paper, drawn from a storage reel 25.
