Patent GB-765525-A (GB)
Title: A process for the preparation of dialkyl monoalkali metal phosphates
IPC: D06M13/292
Filed: 1955-02-10
Abstract: A dialkyl monoalkali metal phosphate is obtained by esterifying an alkanol with phosphorus oxychloride in a solvent which consists wholly or mainly of one or more aliphatic hydrocarbons and/or halogenated aliphatic hydrocarbons and mixing the entire resulting liquid reaction mixture, including the solvent, with a quantity of caustic alkali solution which is at least sufficient to cause hydrolysis and neutralization of the reaction mixture.  The solvent should preferably contain not more than 7 per cent by weight of aromatic compounds and petroleum fractions which are free from or are poor in aromatic compounds are very suitable.  It is also desirable to include in the reaction mixture during the caustic alkali treatment a small quantity of a polar organic substance which has no emulsifying effect, e.g. an alcohol which does not contain an aromatic group, such alcohol being preferably the same alcohol as that with which the esterification is effected.  It is preferred to employ the alkanol and the phosphorus oxychloride in the exact molar ratio of 2 : 1.  The esterification is preferably effected at between 0 DEG  and 40 DEG  C. whilst the combined hydrolysis and neutralization is preferably effected at between 40 DEG  and 60 DEG C.  Specified alkanols are those containing 4 to 17 carbon atoms in the molecule and particularly the heptyl, octyl and nonyl alcohols and the alcohols may be straight chain or branched.  In an example phosphorus oxychloride is added over a period of 3 hours to a mixture of aromaticfree gasoline of boiling range 80 DEG  to 110 DEG  C. and 3,5,5-trimethylhexanol-1 the temperature being kept between 15 DEG and 20 DEG  C. by cooling.  The mixture is then stirred for another hour and part of the hydrogen chloride formed is then allowed to escape, the remainder being removed by gentle heating.  The reaction mixture is then added at about 50 DEG  C. to an excess of 10 per cent aqueous solution of sodium hydroxide and stirred until the caustic alkali content is constant.  The mixture is then allowed to stand to form two layers which are separated.  The upper organic layer is distilled to remove gasoline and distilled water is then added and the unconverted nonanol removed by vacuum steam distillation.  The residue comprises dinonyl sodium phosphate and water with small amounts of nonanol and monononyl disodium phosphate.  The dinonyl sodium phosphate is stated to be useful as a wetting agent and as an agent for imparting anti-static properties to synthetic fibres. Specification 459,520, [Group IV], is referred to.

Abstract: 138,901. Locomotive Superheater Co., (Assignees of Brandt, C. A. W., and Langelier, A. J.). Sept. 26, 1918, [Convention date]. Pipe-end closing; forging-machines.-In the manufacture of U-shaped pipe bends for boilers, superheaters, &c., as described in Specifications 6304/15 and 100,223, the incomplete bend 83, Fig. 10, is held, while the end is closed in, by improved fluidcperated clamping and feeding means. The bend is placed between jaws 40, 41, Fig. 4, the former being operated by a toggle 45 and hand-lever on the spindle 43 and locked when closed by the segment 44 engaging a corresponding face 42 on the jaw. The jaws are carried by a table 18 formed with a sleeve 16 to slide on the cylinder 14 and connected to the hollow plunger 17 thereof by a bar 20 which passes through slots 19, Fig. 3, in the cylinder 14 and fixed plunger 15, this closely fitting the bore of the plunger 17. Water is admitted through the valve 27 and port 25 to move the plunger 17, table 18, &c. to the left, the inside of the plunger 17 being connected to exhaust through ports 23, 37<1>, pipe 37, Fig. 1, and ports 34, 36 of the valve 27. During this movement, a fixed cam surface 76, Fig. 1, presses down a roller 73 of a lever 72 against the action of a spring 64, Fig. 7, which causes the piston 61 of the valve 57 to move to the left from the position shown, thereby admitting air through ports 68, 62, 60, 58 to the cylinder 55, Fig. 4, and moving the piston 54 to the right to operate the lever 51 and toggle 39 and close the jaw 41 with great power. The bend 83 then enters between dies 6, Fia. 3, which are rotated inside a ring of fixed rollers 4 to act radially in the known manner. The valve 27 is then reversed causing the return of the table and the release of the work by the jaw 41 by the cam 76 releasing the lever 72 so that the spring 64 returns the valve 61, Fig. 7, thereby admitting air through ports 68, 62, 67, 66 to the space on the other side of the piston 54, Fig. 4. Air is exhausted from the cylinder 55 through ports 66, 69 or 58, 65, 69 in the position shown in Fig. 7. The cylinder 14 is carried at one end by a plate 12 hinged to the framework 2 and at the other bv a foot 81 resting on a curved rail 80 so that, after releasing the clamps 79, Fig. 4, the whole can be swung aside. Rings 9, 10 are easily removable for inspection or repair of the dies 6 &c. The jaws 40, 41 have extensions 84, Fig. 10, which engage the sides of the bend closely and are shaped to enter the dies 6 without being struck thereby. Lugs 30, Fig. 1, on the sleeve 16 are adapted to slide on fixed bars 29 and engage stops 31, 28 to limit the stroke of the table 18. After the end has been closed as shown in Fig. 12, the teat is cut off and the root smoothed by a hand hammer. The bulges at the points 85 are flattened in a press.

Abstract: 526,239. Electromagnetic relays. FLETCHER, H. L. Feb. 8, 1939, No. 4194. [Class 38 (v)] [Also in Group XL] Wireless receiving apparatus of the kind adapted, on receipt of a predetermined carrierfrequency signal, to actuate an alarm device or perform a similar operation, comprises a detector 4 of the non-energy consuming type having an input circuit 1, 2 tunable to the carrier frequency and, associated with its output circuit a relay 10 arranged, on receipt of the signal to open and close periodically a circuit containing a local voltage source 7, said relay being operated by energy derived from the received signal, the arrangement being such that energy released from the local source at each closure of the circuit is stored in a device which after a predetermined time causes an alarm 14 or like device to operate. The relay 10 is of the vibration galvanometer type, the moving coil 10 being mounted on a phosphor bronze or like strip so as to be free to vibrate between the poles of a permanent magnet, the natural period of vibration of the coil being adjustable by varying the tension of the strip. The strip carries a moving contact 11 which is arranged to make and break with a fixed contact 12 twice during each cycle of vibration of the coil. Each time the contacts close, a relay 13 shunted by a condenser 15-is energized, and after a predetermined interval, during which the condenser is charging up, the relay 13 closes its contacts and the device 14 is energized. The apparatus is effective when the carrier frequency applied to the input circuit 1, 2 is modulated by a continuous audiofrequency as the natural frequency of vibration of the coil 10. In a modification, Fig. 2, the relay 10 moves a contact 18 into the field of a permanent . magnet 19, where the contact is held against a fixed contact 20 until it is released, after a predetermined interval, by the energization of a winding 23 through a delayed-action relay 22. Closure of the contacts 18, 20 energizes the relay 22 and also a thermal relay 21 which, after an interval, closes the circuit of the alarm 14, In a further modification, Fig. 3 (not shown), the energization of the relay 10 closes a maintaining circuit for the relay and also energizes a delayed-action relay which, after an interval, first operates the alarm device and then opens the maintaining circuit. Specification 526,230, [Group XL], is referred to.
