Title: Improved method of producing oxidized carbon
IPC: C01B31/00
Filed: 1926-07-07
Abstract: 255,068. Burgess Laboratories, Inc., C. r., (Assignees of Brown, B. K., Storey, 0. W., Silver, C. A., and Collinson, G. T.). July 7, 1925, [Convention date]. Solid oxide of carbon.-A solid oxide of carbon is obtained by anodic oxidation of carbon in an electrolyte comprising an oxygen containing anion under conditions which preclude the formation of substantial amounts of gaseous oxides. The electrolyte preferably consists of dilute nitric acid, containing e.g. 30 per cent of weight of acid, or an equivalent mixture of sodium nitrate and dilute sulphuric acid. Sulphuric acid alone may be used but the yield of the solid oxide is low in this case. Other suitable electrolytes are a solution of sodium chlorate, or of a mixture of sodium chlorate and sodium nitrate. Oxidizing compounds such as chlorates and bichromates and chromium trioxide improve the action when added to nitric or sulphuric acid baths. The anode may be solid but is preferably of graphite crushed so that the largest particles pass a 10 or a 20 mesh sieve, while a quantity of finer material is also present. It may consist of a mixture of powdered graphite and other carbonaceous material moulded with a hot binding agent which becomes solid when cool, 10-15 per cent of the binder may be retained in the anode. The moulding pressure may be 1000- 5000 lbs. per sq. in. Suitable binders are paraffin wax, ceresin, shellac, and rosin, alone or hardened by lime or by manganese or zinc oxides. Rubber may be used and may be vulcanized during moulding by the addition of sulphur with or without accelerators. Inorganic binders such as low melting-point fusible slags and water glass may also be used. The binder should preferably be a repellent of water and should be only slightly attacked, if at all, by the electrolyte. When a solid anode is used it should be treated to confine oxidation and disintegration to the surface by impregnation with a water-repelling substance such as paraffin, benzol, rosin, lubricating oil, gasoline, naphtha, or carbon tetrachloride, or with a substance such as sodium silicate which reacts with the electrolyte. to produce a precipitate or gel. The temperature of electrolysis should be below 70‹ C. and is preferably 20-25‹ C. When benzol has been employed as impregnating agent, the temperature should be below 0‹ C. The currrent density should be below 10 amps. per sq. ft. of anode surface. The cathode should be of small surface. The oxidation is only carried far enough to produce a mixture of carbon and the oxide which is deposited as a sludge at the bottom of the cell. The product is washed with water and the paraffin or other binder is removed with carbon tetrachloride or benzol. It has a dull black colour, deflagrates on heating, oxidizes ferrous sulphate in acid solution and acts as depolarizer in a galvanic cell.

Abstract: 847,466. Stuffing-box substitutes. GENERAL MOTORS CORPORATION. May 21, 1959 [May 26, 1958], No. 17256/59. Addition to 791,934. Class 122 (5). In a gas-turbine shaft bearing and sealing assembly of the type disclosed in the parent Specification which is referred to, and comprising a sleeve 40 supported by a cage 30 for axial movement but prevented from rotation and having a seal ring 42 urged by a spring 55 into contact with one face 56 of a metal ring 20 secured to the shaft 10, a further sleeve 41 is coaxially secured to the sleeve 40, as by bolts 54, and has a seal ring 43 which, when the ring 42 is in contact with the face 56 of the ring 20, has a slight clearance with the other face 57 of the ring 20. The sleeve 40 is slidably sealed in a bore 45 of the cage by a piston ring 44. The external diameter of the seal ring 42 is greater than that of the ring 43. If relative movement between the shaft 10 and the cage 30 due, for example, to expansion, occurs in a direction tending to separate the rings 20 and 42 and due to the sleeve 40 sticking in the cage bore 45 the ring 42 becomes unseated, the ring 43 contacts the face 57 of the ring 20 and the gas pressure leaking past the ring 42 acts on the sleeve 41 to assist the spring 55 to move the sleeve 40 so that the ring 42 again contacts the ring 20. The remaining subject-matter is generally the same as that described in the parent Specification.

Title: Improvements in or relating to aircraft with freely rotative wings
IPC: B64C27/02
Filed: 1931-06-15
Abstract: 379,780. Aircraft with rotary wing systems; folding wings. LA CIERVA, J. DE, Bush House, Aldwych, London. June 15, 1931, No. 17300. [Class 4.] In an aircraft having a rotary wing system comprising blades hinged for movement in the plane of rotation and provided with stop means coacting with relatively fixed parts of the rotor hub for limiting their swinging movements, means are provided for rendering the stop means inoperative to permit of any blade being swung through a large angle in order to fold the rotor. As applied to an aircraft having a rotor comprising three blades 15, Fig. 2, a hub 17 freely rotatable on a vertical axle 16 is formed with three pairs of jaws carrying hinge pins 18 perpendicular to axle 16 on which are rotatably mounted link members 19 connected to fork-ended blade roots 20 by vertical hinge means comprising a sleeve 26 rotatively mounted in the end of link 19 by means of a floating bush 27. Member 26 is secured between a washer 30 and a member 28 having a securing spindle 29. Member 28 is free to rotate in the sleeve 26 and has riveted to it a plate member 22 carrying the stop means 23. Plate 22 and member 28 are normally coupled to share the angular movements of the spar 20 by a split collar comprising one part 43, Fig. 5, attached to plate 22 and another part 46 held on spar root 20 by a readily-detachable bolt 47 so that the spar is normally limited in its swinging movements by the stops 23. By detaching bolt 47 and the half collar 46 the spar may be swung independently from plate 22 to the position shown in Fig. 2. To prevent violent swinging of the spar when free friction washers 39, 40 are inserted between the fork ends and member 28 and washer 30, respectively. The spar swinging movements in flight are damped by mechanism comprising ring plates 24, 25 mounted on plate 22 and faced with friction material at 34. Plates 24 comprise locating tongues 24a anchored between lugs 33 on link member 19 and plates 25 comprise tongues 25a anchored between flanges 32 formed on plate member 22. A disc 35 acting through a cushion ring 35a maintains the pressure on the friction discs. The floating bush 27 is lubricated from a nipple 37 by means of ducts 38 in the spindle 29 and holes in member 26. Outer parts 14a of fixed wings 14, Fig. 6, may be folded upwardly about hinges 52, 53 disposed outside the bracing strut and undercarriage attachments. Wing parts 14a include an aileron 60 having a tubular main spar 61 operated by a torque tube 63, Fig. 8. Spar 61 and tube 63 carry brackets 64, 65 respectively at their abutting ends interconnected by a hinge pin 66 coaxial with the hinge pins of wing hinges 52, 53. The aileron operating mechanism thus need not be disturbed when the wings are to be folded. Locking pins 69, 73 normally have their handles held to the respective wing spar by spring clips and are fitted with safety pins 74. Specification 264,968, [Class 4, Aeronautics], is referred to.

Filed: 1919-07-12
Abstract: 144,127. Wellman Smith Owen Engineering Corporation, and Kemp, A. V. July 12, 1919. Multiple-way valves.-A reversing valve for controlling the flow of gases or vapour, more particularly adapted for regenerative furnaces comprises a casing A having a gas or like inlet a, an outlet B to chimney and two regenerator connexions a<3>, a<4>, the valve proper being a watersealed hood C adapted to cover the inlet a and one or other of the ports a<3>, a<4>. In addition there is a cover I for the inlet a, which is automatically lifted by the hood when the latter drops to its seating, but closes the inlet to prevent waste of gas when the hood is raised on reversal. A shaft J and lever j allow the cover to be raised by hand if desired. The correct sequence of lifting and rotation for the cover C is obtained by the device shown in Figs. 2 and 6. Motion is imparted to the hood by rotation of a spider E carried by rollers e on a cam track F. The hub e<2> of the spider carries pins g which engage slots h, widened at the base, in a sleeve H which in turn has a sliding key-way connexion with the valve spindle c. Thus, owing to the lost motion afforded by the slots h, rotation of the hood does not start till it is clear of the water seal.

Title: The preparation of mixed polyphosphates of sodium and potassium
IPC: C05B13/06
Filed: 1965-04-27
Abstract: Mixed polyphosphates of sodium and potassium of general formula (Na,K)x+2PxO3x+1 wherein x\sF 2 are prepared by treating calcium phosphate ore with a solution of H3PO4 and sodium or potassium sulphate, filtering off the solids containing CaSO4 and partially neutralizing the filtrate with a basic sodium and/or potassium compound, e.g. oxide hydroxide carbonate, or bicarbonate, then filtering and finally evaporating, and calcining to form the polyphosphate. The amount of sulphate added is such as to convert into CaSO4 all the calcium ions in the phosphate ore.  The amount of base added is such that the ratio of sodium and potassium ions to phosphorus atoms is equal to x+ 2/x .  If the H3PO4 solution is impure it can be treated with Na2SO4 and any impurity such as Na2SiF6 is removed as a separate step. Any SO4- ions present in the solution after the filtering off of the CaSO4 may be removed by adding a Ba salt as a separate step and filtering. The process may be continuous. The Na: K ratio in the product is preferably 0.3 to 0.7:1. The amount of H3PO4 added may be such that the solution has a P2O5 content of 25 to 35% weight.  The K2SO4 and ore that are used in the first stage may be ground.  The amount of K+ ions added in the first stage can be such that the K2O/P2O5 ratio is below 0.5 and this reaction time is 2 to 6 hours at a temperature between 35 DEG  and 55 DEG  C.  During the neutralization the reaction time may be 1/2 to 2 hours at temperatures between 50 and 100 DEG  C.  The evaporation may be to a salt concentration of 48 to 55% weight when some of the calcined product can be added.  Calcination may be at a temp. between 250 DEG and 500 DEG  C.
