Title: Improved process for the preparation of metal dialkyl dithiophosphates
IPC: C07F9/165
Filed: 1960-09-20
Abstract: A metal salt of a dialkyl dithiophosphoric acid is obtained by reacting phosphorus pentasulphide containing less than 27,6 weight per cent of phosphorus with a C1-C16 alkanol in a mole ratio of about 4 moles of the alcohol per mole of the phosphorus pentasulphide at 100 DEG  to 250 DEG F. for 1 to 6 hours while maintaining the specific gravity of the reaction mixture in the range of 1,015 to 1,042 to obtain a dark coloured reaction mixture, cooling the reaction mixture and separating solids therefrom, neutralising the purified dark product comprising the dialkyldithiophosphoric acid with a basic inorganic polyvalent metal compound at 120 to 250 DEG F., heat soaking the resulting dialkyl dithiophosphoric acid salt at 120 to 250 DEG F. for 2 to 12 hours while maintaining the water content thereof in the range of 0,5 to 4 weight per cent and the pH in the range of 5,8 to 6,6, then separating substantially completely inorganic solids from the heat soaked acid salt by filtering while maintaining the water content thereof in the range of 0,5 to 4 weight per cent and drying the purified acid salt to a water content not exceeding one weight per cent.  In a modification the purified dark product comprising the dialkyl dithiophosphoric acid obtained as above is neutralised with an alkali metal hydroxide to form an alkali metal dialkyl dithiophosphate and the latter then reacted with an equivalent amount of an inorganic divalent metal compound to form the corresponding divalent metal dialkyl dithiophosphate.  In either form of the invention about 0,1 to 3,0 weight per cent of free sulphur may be added at any stage prior to the neutralisation step.  Preferably it is added to the purified dark product used in the neutralisation step.  The polyvalent metal compound may be a compound, preferably an oxide, of an alkaline earth metal, zinc, lead, cadmium, copper, cobalt or nickel and the polyvalent metal compound is preferably introduced into the reaction vessel in the form of an alcoholic slurry.  The phosphorus pentasulphide containing less than 27,6 weight per cent of phosphorus may be obtained by heating together phosphorus and sulphur in the proportions necessary to give the said phosphorus content.  It is preferred to use a phosphorus pentasulphide containing from 26,0 to 27,2 weight per cent of phosphorus.  Examples are given for the preparation of zinc di-isobutyl dithiophosphate, cadmium and lead di(methyl isobutyl carbinyl) dithiophosphates and a calcium di C12-alkyl dithiophosphate.  The products are useful as lubricating oil additives.  Specification 866,502 is referred to.

Abstract: 975,067. Cleaning pipes. E. L. WARD. Aug. 22, 1963 [Aug. 24, 1962; Dec. 8, 1962], Nos. 32529/62 and 46406/62. Heading F2N. A device usable in cleaning the interiors of pipes and tubes comprises a flexible elongated member forming a rotatable flexible spine which carries a plurality of axially-spaced, transverse discs 2 of larger diameter than that of the spine each having a radially directed slot or slit extending inwardly from the periphery, the discs being inclined to the main axis of the flexible spine and held in position by associated locating and retaining means. The spine is formed of a helical wire coil 1 and the discs 2 are inserted between the turns of the coil. The radial slot in each disc accommodates the wire so that the disc can be centred but the width of the slot is such that the discs are distorted when assembled and the edges of their slots become separated axially and present axially-spaced leading and trailing edges. The discs are retained by a wire or flexible rod 7 along the axis of the coil which passes through holes in the centre of the discs, and are located by sleeves 9 inside the coil. Alternatively, the locating sleeves may be outside the wire coil. The device is adapted to be rotated by closely coiling the wire and reducing the diameter of the coil at one end, termed the inner end, forming a spigot 10 for fitting to a rod. At this end the wire or rod 7 is held by a ferrule 12 and at the outer end by a ferrule 13, between which and the outer disc is a spring 15. The discs may be of increasing diameters from the outer to the inner. The wire coil may be protected by a plastic covering. The outer end of the wire coil may be extended to carry guide rollers.

Abstract: 1,015,230. Feeding documents to machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 16, 1963], No. 32646/64. Heading B6B. A document feeding apparatus comprises a driven part elastically coupled to a document holding part, so that when the latter is arrested the driven part can carry on until its kinetic energy is absorbed by the coupling. As shown, the portion 110, driven by the motor 30 via a non-reversible clutch 32 and a belt 40, is connected to a document gripper 10 by bands 54, 56 attached to the circumference of spring- loaded rotatable discs 122, 190 attached to the portion 110. For feeding in the document the motor drive is interrupted and stops 54, 64 arrest the gripper which is opened by cam 74. The kinetic energy of the driving system is absorbed by the advance of 110 and the rotation of the spring-biased discs. Backward motion of the latter is prevented by the clutch 52. For onward feeding the motor is restarted and the stops 54, 64 depressed electromagnetically. During the forward motion the gripper is attracted towards the member 110 by the spring bias. The document is arrested in a similar manner at the document reading station. Provision here is made for reading the document in two successive halves. With the document arrested by stops 85, 86 the first half is read and the kinetic energy stored as potential energy in the biasing springs for discs 122, 190. This energy is then, used on depression of stops 85, 86, to advance the gripper, without using the motor 30, to the second set of stops, where the second half of the document is read. The document is then driven round beneath of the apparatus where a cam opens the gripper to deposit the document in tray 16.

Title: Improvements in and relating to gaseous electric discharge devices and methods of making the same
IPC: H01J17/06
Filed: 1932-11-21
Abstract: 411,931. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Foulke, T. E. ; 30, Evelyn Place, Nutley, New Jersey, U.S.A.) Nov. 21, 1932, No. 32873. Convention date, Nov. 21, 1931. [Class 39 (i).] Discharge tubes of the cathode-glow type emitting blue light and ultra-violet rays are made by coating the electrodes with an oxygencontaining compound, such as carbonate or nitrate, of an alkali or alkaline earth metal, decomposing the compound to oxide in the tube, by heat, admitting a filling of argon containing 5-20 per cent of nitrogen at 6-20 mm. pressure, reducing the oxide to metal by a high-frequency bombardment and clearing up any oxygen evolved. Semicircular nickel electrodes 2 may be coated on the back with aluminium powder as described in Specification 397,107 to confine the glow to the front of the electrodes, and on the front by spraying with a mixture of equal parts of barium and strontium carbonates, using a binder of a 5 per cent solution of nitrocellulose in cellulose acetate. The electrodes are mounted on leads 3 in a lime-glass or fused silica bulb 1 and the leads are connected to contacts on a cap 5 with a resistance 6 in one lead. The bulb is exhausted and the electrodes are heated by a high-frequency field to decompose the carbonates to oxides and the binder to carbon. A getter pellet 4 is then heated to vaporize magnesium or other metal on to the lower part of the bulb and a filling of argon containing 10 per cent of nitrogen at 10-12 mm. pressure is introduced and the bulb is sealed. The lamp is connected to a spark-gap oscillator generating highly-damped oscillations, the discharge forming an electrode surface of work-function of the order of 1.3 volts with barium and strontium particles bonded together and to the electrode by nitrogen particles. The evolved oxygen is absorbed partly by the electrodes and mainly by the magnesium film. The lamp is then ready for use on low-voltage A.C. or D.C. supplies. Specification 365,147 also is referred to. The Specification as open to inspection under Sect. 91 comprises also references to bulbs of the materials known under the Registered Trade Marks "Corex," Pyrex" and "Uviol," to the use of other alkali or alkaline earth compounds, such as nitrides or azides, instead of carbonates, and to distilling the alkali or alkaline earth metal on to the electrodes before the discharge treatment. This subject-matter does not appear in the Specification as accepted.
