Title: Improvements in or relating to releasable support means for roofs in underground mines
IPC: E21D15/60
Filed: 1951-07-02
Abstract: 735,103. Mine roof supports. MUSCHAMP, N. J., COWLISHAW, F. July 2, 1952 [July 2, 1951], No. 15704/51. Class 20 (2). A mine roof support comprises uprights 1, 2 connected by bridge plates 3 formed with slots 4, 5 and having inclined faces 6, 7 on which ride chocks 8, 9, the chocks being retained in operative positions by links 12, 13 having pivotally mounted at their free ends cam discs 17, 18 which engage in correspondingly shaped branch portions 4b, 5b of the slots 4, 5, the arrangement being such that when under load the ends of the links 12, 13 are raised by a lever 16, the cam discs rotate and pivot about the corners A, B of the branch portions 4b, 5b to permit an initial lowering of the chocks before complete release of the cam discs from the branch portions. The upper curved parts 4h, 5h of the slots may be formed by a movable member 19 which retains the cam discs in the branch parts of the slots until positively raised by the lever 19. As shown the edges 4c, 5c of the branch parts and the corresponding edges of the cam discs are straight and vertical, thus requiring a vertical movement of the discs before rotation and initial movement of the chocks 8, 9 starts: these edges may, however, be arcuate, thus permitting movement of the chocks as soon as the cam discs are raised. These edges may also be so arranged that the load on the chocks tends to cause movement of the cam discs to release positions, the discs being positively held in operative positions by a member which when moved away permits the chocks to lower automatically. Specification 684,403 is referred to.
Patent GB-965693-A (GB)
Title: Improvements in or relating to sols of urania,plutonia and thoria
IPC: B01J13/00
Filed: 1961-05-01
Abstract: In a hydrothermally stable aqueous sol of thoria, urania, or plutonia, the metal oxidel particles are spheroidal and have a surface layer of cladding which is zirconia or titania, or in the case of urania and plutonia may be silica, in amount sufficient to give the particles a negative charge.  The sol contains sufficient base, generally alkali metal hydroxide (e.g. sodium hydroxide) to give a pH of 7.0 to 11.0, the sol being otherwise electrolyte free. The The coated particles have a weight median diameter greater than 30 mu. The weight ratio of urania or plutonia to silica is 2 : 1 to 3 : 1 and or urania, plutonia, or thoria to zirconia, or titania is 2 : 1 to 10 : 1.  The sol is prepared by rapidly mixing a 5 to 10% metal oxide sol with a freshly prepared 1 to 2% cladding oxide sol of micelle size less than 5 millimicrons without allowing the mixture to remain at the isoelectric point for an appreciable time, and then adding sufficient alkali metal hydroxide to give a pH of 7.0 to 11.0. Zirconia cladding may also be effected by adding dropwise a dilute (e.g. 5 to 10%) aqueous solution of a zirconyl salt (e.g. zirconyl nitrate) with vigorous stirring to a de-ionized metal oxide sol, and de-ionizing the resulting sol.  The electrolyte content of the resulting sols may be reduced so that the sol has a specific conductance of 10-5 to 10-2 mho./cm., by heating the sol under non-evaporative conditions and after cooling contacting it with a de-ionizer. The de-ionized sol may be concentrated to a solids content of up to 60%.  The initial metal oxide sol is prepared by removing at an elevated temperature anions from a dilute aqueous solution of the metal salt of a strong monobasic acid (e.g. nitrate, chloride or perchlorate) by electrodialysis, or dialysis using an anion-permeable membrane, ion exchange using a resin in the hydroxide form, decomposition of the salt of a volatile acid, or electrolysis of a metal oxide salt, the anion of which is oxidized to a volatile compound or state.  The silica sols may be prepared by de-ionizing sodium silicate by passing it through a cation exchange resin. The sols may be used in an aqueous homogenous nuclear reactor. Specification 910,212 is referred to.

Title: Process for the treatment of phosphatic rocks
IPC: C05B11/06
Filed: 1932-06-06
Abstract: In the process described in the parent Specification, comprising dissolving crude phosphate in nitric acid and separating calcium as a double salt with for instance ammonium nitrate, residual calcium and iron present in the solution remaining after separating the double salt are precipitated respectively as dicalcium phosphate and ferric phosphate by neutralizing the solution with ammonia say at 100 DEG C.  The double salt is freed from iron precipitated therewith as the complex Fe(PO4)3.H6.NH3 by treatmen with warm calcium nitrate solution, which dissolves only the double salt. The mixed dicalcium and ferric phosphate precipitate is either dissolved in the nitric acid used for dissolving the phosphate or else added to the acid solution obtained prior to separating the double salt, whilst the solution remaining after separating the mixed phosphates is further treated with ammonia and cooled to precipitate a mixture of diammonium phosphate and ammonium nitrate.  Residual ammonium nitrate solution, after concentration if necessary, is returned as diluent for the solution remaining after separation of the double salt.

Abstract: 860,779. Valves. KARR, R. J. May 21, 1958 [June 21, 1957], No. 16377/58. Class 135. A pressure regulator suitable for use in the calibration of pressure gauges or for other applications where close control of the pressure is required comprises a ball 22 mounted with close radial clearance, e.g. 0.00025 inch, in a tubular element 18 and loaded towards a seat 17 by weights 26 mounted on a carrier 24. The tubular member 18 is mounted on a housing 10 which has an inlet 20 opening to an annular chamber 19 and an outlet 23 leading from the seat 17 to a conduit 13 in which the regulated pressure is to be maintained. The seat 17 is shaped to conform to the ball 22 and has channels 21 in its surface for the passage of fluid to the outlet 23. The length of the tubular member 18 is such that its mouth is just above the horizontal equitorial plane of the ball. The interior of the member 18 may be cylindrical at its mouth as shown or it may be flared or stepped. In operation, a restriction 12 in the pressure fluid supply conduit 11 is opened progressively until the ball is raised from its seat 17 by the pressure of fluid between the restriction provided by the clearance between the ball 22 and the member 18 and a restriction provided by an annular clearance between the upper part of the seat 17 and the interior of the member 18. The pressure in the outlet 23 is then determined by the weights 26 and the projected area of the ball 22. Any tendency of the ball 22 to move inwardly or outwardly of the mouth of the member 18 due, e.g. to addition or removal of weights 26, is corrected by the provision of a valve 32 which controls flow in the conduit 11 in accordance with the pressure ratio across the restriction 12. The valve 32 comprises a closure member 35<SP>1</SP> actuated by interconnected diaphragms 38, 39 of unequal area and subject respectively to the pressures before and after the restriction 12.
