Title: Flame retardant systems and compositions
IPC: D01F6/10
Filed: 1964-02-10
Abstract: Tetrabromophthalates of aluminium (see Specification 1,061,372), potassium, calcium, silver, tin and zinc are prepared by treating tetrabromophthalic anhydride with aqueous potassium hydroxide, separating the potassium tetrabromophthalate formed, and if necessary further treating it with the appropriate metal chloride or nitrate. Reference is also made to the cupric, nickelous, cerium, ferric, ferrous, mercuric, beryllium, yttrium, and indium tetrabromophthalates.ALSO:A flammable polymeric material is intimately admixed with a composition of two or more components that react under the conditions of combustion of the polymeric material to produce a flame retardant, one component being a metal salt of a halogen-containing carboxylic acid. Flammable polymeric materials exemplified are polyethylene, polypropylene and polystyrene. The second component of the flame-retardant-producing composition may be a compound of arsenic, tin, titanium, boron, antimony or bismuth. The flame-retardant produced is thus an inorganic halide.  In examples, polyethylene is milled with (i) antimony oxide and (ii) various metal tetrabromophthalates, aluminium tetrachloro- or tetraiodophthalate, aluminium triiodobenzoate, barium tetrabromobenzoate - o - sulphonate, or aluminium or lead eudo-1,4,5,6,7,7-hexachlorobicyclo (2.2.1) - 5 - heptone - 2,3 - dicarboxylate, together with other constituents, and polypropylene and polystyrene are mixed with antimony oxide and the aluminium dicarboxylate above.

Filed: 1929-02-19
Abstract: 331,263. Shaw, C. G. Feb. 19, 1929. Waterproofing; proofing processes and compositions. - Leather is impregnated with rubber cement with or without fillers and vulcanized by treatment with an ultra accelerator and sulphur. Suitable ultra-accelerators are piperidine-pentamethylenedithio-carbamate, or zino-ethylxanthate. The impregnation may take place under vacuum and the vulcanization may be effected under ordinary conditions or with the use of heat and pressure. Where sulphur is present in the leather, as the result of the method of tanning employed, it may not be necessary to add any to the materials.

Abstract: 638,286. Stencilling-apparatus. SOLAR ENGINEERING EQUIPMENT CO. Feb. 27, 1947, No. 5689. Convention date, Sept. 7, 1946. [Class 100 (ii)] A machine for stencilling on bottles &c. comprises a pair of stencils movable along parallel paths so as to engage an article carried by a workholder 1, squeegees 3, 4 for forcing colour through the stencils, and a speedvariation device driven from one of the stencils and driving the other, whereby the second stencil, which engages the shoulder of the bottle, is driven at an appropriately reduced speed. Movement of the squeegees into operative position is prevented in the absence of an article. Workholder.-A cone 29 engages the mouth of the bottle and presses the base into a cup 28 rotatable by a pulley 31, cones 30 guiding the bottle into position. The cone 29 is carried by an arm 33a rocked about a pivot 34 on a support 1 by a rod 35 connected to a lever 36 oscillated from a cam 15, whereby the chuck is closed during the movement of the stencils. The support 1 is raised and lowered about a pivot 26 by a cam 14 acting through a link 45. Reciprocating the stencils.-A stencil for the body of the bottle is mounted in a holder 5 on a carriage 7 reciprocated on a guide plate 63 by a rod 66 actuated as described in Specification 600,212 and a stencil for the shoulder is mounted in an angularly-adjustable holder 6 on a carriage 8 sliding on guides 83 on the carriage 7 and actuated therefrom through a speed-variation device in the form of a stepped pulley 9. Cables 105, 114 stretched between posts 104, 115 on the carriages 7, 8 are wrapped around the pulley. Each carriage has grooved rollers engaging the guide plates, one roller of each set being spring-pressed. Each cable may be positively connected to the pulley, as by passing the cable through an eye to which the cable is clamped by a screw. Squeegee mechanism.-The squeegee holders 3, 4 for the body and neck respectively, are carried by an arm 50 fixed to a frame 48 resiliently supported within a frame 47 pivoted in arms 46, as described in Specification 600,212. The shoulder squeegee is carried by an arm pivoted to a bracket adjustable along the arm 50 and can adjust itself to irregularities under the action of a spring. Preventing lowering of squeegees when no article is present.-The frame 47 is prevented from descending by mechanism similar to that described in Specification 600,212.

Abstract: 767,252. Welding by fusion. AIR REDUCTION CO., Inc. Feb. 25, 1955, No. 5772/55. Class 83 (4). Metals having a boiling-point greater than 3600‹ K. and/or a thermionic emission rate at boiling-point greater than 1000 cms. per square centimetre are electric welded using a gasshielded arc and a consumable electrode of substantially the same metal as the work.

In direct current welding, the electrode 10 is made the cathode and the work 23 is made the anode. A pistol type welding head has a manually-actuated switch 27 which controls a motor 14 driving the feeding rollers 13 and a solenoid actuated valve 19 in the supply pipe 20 carrying the shielding gas which is an inert gas, e.g. argon and/or helium.

Abstract: 846,681. Speed governors. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. Feb. 19, 1959 [April 24, 1958], No. 5794/59. Class 57. In speed-regulating devices for internalcombustion engines comprising an unbalanced throttle valve 2 arranged in the induction pipe 1 and urged towards the open position by elastic means against the action of the flow of gases in the pipe and/or the engine suction; the force exerted by the elastic means is varied to compensate for changes in ambient atmospheric pressure. The valve is rotatably mounted on a shaft 3 and urged towards its open position by a coil spring 8 tensioned between the valve and a sleeve 11 axially adjusted by a nut 13 screwed on a support 14, the sleeve and the nut having flat surfaces engaging corresponding surfaces on a cover 15. An aneroid capsule 16 housed in a cover 20 open to atmosphere through an aperture 21 is fixed at one end to the cover and at the other end to a rod 17 connected to a lever 18 fast with a pinion 19 engaging a rack 14a on the support 14. When the atmospheric pressure decreases the capsule extends and rotates the pinion anticlockwise, thus reducing the tension of the spring 8. Similarly, an increase in atmospheric pressure results in an increase in the tension of spring 8. The engine speed is thereby kept substantially constant irrespective of variations in atmospheric pressure. Pins 6 on the shaft 3 co-operating with abutments 7 on the valve 2 provide a lost-motion connection between the valve and the accelerator lever 5 secured to shaft 3. In a modification, Fig. 2 (not shown), the coil spring 8 is replaced by a flat spring whose flexibility is varied by movement of the capsule 16.

Title: Process for separating iron from phosphoric acid containing the same
IPC: C01B25/234
Filed: 1965-02-11
Abstract: In the separation of phosphoric acid and iron values contained in solution in an organic amine which is water-insoluble or capable of forming a water insoluble salt, or contained in solution in a water insoluble salt of an organic amine, or contained in solution in a water-insoluble quaternary ammonium compound, the phosphate values are stripped from the solution with an aqueous stripping medium in the presence of an agent which forms a complex with the iron which remains in the organic phase during the stripping operation.  The phosphate values may be obtained as phosphoric acid or a solution of a salt of phosphoric acid depending on the stripping medium, which may be acidic, basic, or neutral, and are preferably water, or an aqueous acid, e.g. HCl, HNO3, H2SO4, when phosphoric acid is the desired product or may be an aqueous solution of a salt or base of an alkali metal, alkaline earth metal or ammonium when a phosphate is the desired product, and preferably the pH of the aqueous phase is below 3. The preferred complexing agent is a polyphosphate, e.g. a tripolyphosphate or a pyrophosphate, and the extractant exemplified is an aqueous solution containing sodium tripolyphosphate and sodium hydroxide.  A long list of suitable amine compounds is given in the Specification, and they are preferably used as solutions in organic solvents, and the amine has the formula R1R2R3N, and the quaternary salt the formula R1R2R3R4N.OH, where R1 and R2 are each a saturated or ethylenically unsaturated aliphatic hydrocarbyl group containing from 7 to 15 carbon atoms, R3 is hydrogen or a saturated, or ethylenically unsaturated hydrocarbyl group containing from 1-18 carbon atoms, and R4 is a saturated or ethylenically unsaturated hydrocarbyl group containing from 1-15 carbon atoms.
