Title: Process for manufacturing pentachlorophenol and alkali pentachlorophenates
IPC: C07C37/02
Filed: 1953-01-02
Abstract: Pentachlorophenol is prepared (as alkali salt) by heating a mixture of hexachlorobenzene with aqueous caustic alkali and a wetting-agent to 180 DEG  to 240 DEG  C. in an autoclave; the wetting agent must be stable to the hot alkali.  The wetting agent may be prepared in situ by adding a fatty acid or oil to the alkaline liquid.  Preformed wetting agents include soaps, acylated hydroxyamines or aminosulphonic acids, and polyglycol ethers or esters.  The action of the wetting agent is to cause the hexachlorobenzene to sink immediately it is added to the alkali. Preferred proportions of reactants are 2 mols. of alkali per mol. of hexachlorobenzene and 3.5 mols. of alkali per litre of solution.  The process may be batch-wise or continuous.  In the examples hexachlorobenzene is reacted with caustic soda in the presence of (1) sodium oleate and (2) stearoyl-methyl-taurine. Sodium pentachlorophenate is precipitated on cooling and is separated; the remaining pentachlorophenol is precipitated on acidifying the solution.

Abstract: 1419071 Piling HUDSWELL MORRICE Ltd 3 Jan 1973 [5 Jan 1972 15 Nov 1972] 357/72 and 52765/72 Heading E1H A pile 32 or 34 is driven into or withdrawn from the ground by an apparatus comprising a ground-engaging base plate 6 supporting a framework 10, 10A, 12, 14, 56, 58, 60, and at least one vertically movable beam 16 or 18 for driving or withdrawing the pile. The apparatus shown is for simultaneously driving a plurality of parallel piles 32, 34 so that subsequent excavation of the earth between the driven piles produces a parallel sided trench. During driving the piles 32, 34 are located in respective slots 28, 30 in the beams 16, 18, the piles being coupled to the latter by passing pins through lugs 38, 40 on the beams and holes 36 in the piles. By contracting vertical piling jacks (42) each of which extends between the framework and a beam end, the piles are driven in, the upward reaction forces being resisted by the weight of the apparatus. Final driving is achieved by inserting members between the undersides of the beams and the tops of the piles. The apparatus is then movable longitudinally to a new location by extending lifting jacks 66 thereby to raise the base plate 6 and framework clear of the ground and then extending traversing jacks (74) located in bearing pads 52 to move upright members 54 on which the framework is vertically slidably mounted. The pads 52 remain in contact with the ground through slots 50 in the plate 6. At the new location the jacks are contracted firstly to lower the framework and then lift the bearing pads 52. Contracting the traversing jacks then moves the pads 52 back to the original ends of the slots 50.

Abstract: 104,963. Thompson, E. J. May 12, 1916. Spray carburettors.-A suction-actuated air valve is connected, through adjustable means with a fuel valve, the relative openings of the two valves being variable, and the lower part of the carburettor casing is fitted with an inlet for hot air which is controlled by a valve normally open. The air valve B has an upper tubular portion 13, a central piston portion 21, and a lower conical portion 14 provided at its base with rack teeth 15, which gear with a pinion 16 actuated through a spindle 17. The valve surrounds a nozzle C with fuel passages 26, 27 fed from a float chamber D. The flow of fuel is controlled bv a needle-valve 35, an enlarged part 36 of which slides in the nozzle, but is prevented from rotating therein by a feather and slot 38. The part 39 of the valve stem is screwed into a sleeve 40, the outer squared portion of which passes through a square hole in a spider 42 extending across the top of the air valve. With this arrangement, the relative positions of air and fuel valve can be varied by rotating the spindle 17. The hot-air inlet 44 is controlled by a valve 45, which is normally open, but which may be closed at starting by the same means that actuate a bell-crank lever 47, which raises the air valve B through a plunger 46 to obtain a charge of fuel only. The upper face of the piston 21 is subjected to suction through an orifice 24, and the lower face to atmospheric pressure through ports 20 in the rack portion 15. The construction shown in Figs. 6 and 10 is the same, in its main features, as that described in Specification 15762/11, and the improvements consist in fitting the block 57 and inclined plane 56 with glass-hard surfaces, making the roller that works over the face 58 and the screw that presses against the face 65 glass-hard, and in providing a casing 65a secured by a clip 66, and a hot-air casing 43a provided with a normally-open manually-actuated valve 45a.

Title: Improved manufacture of sodium perborate
IPC: C01B15/12
Filed: 1924-01-11
Abstract: Carbon dioxide is passed into a reaction mixture of sodium peroxide water and boric acid or alkali borates so as to leave a sodium carbonate solution containing some bicarbonate, for instance 20 per cent more carbon dioxide may be used than is necessary to produce normal sodium carbonate.  To the mother-liquor, if desired before the separation of the perborate, is added more sodium peroxide and boric acid or borate, and, if desired, additional sodium bicarbonate may also be added, in which case the amount of the other reagents added are correspondingly increased.  The total quantity of sodium perborate is then separated, and sodium carbonate solution remains. The stability of the perborate may be increased by adding alkali or alkaline earth (including magnesium) silicates, or organic compounds such as phenols or their substitution products such as cresols or mixtures of such substances.  Specification 503/06 is referred to.
