Abstract: 946,231. Axial flow pumps. W. TIRASPOLSKY. April 28, 1960 [April 28, 1959], No. 15034/60. Heading F1C. An axial flow pump for delivering muds or sludges containing heavy abrasive material for drilling the ground has a branch conduit leading from the pump discharge to a purifier which feeds purified liquid to a disc type axial thrust balancing device and to intermediate bearings of the pump and the separated heavy or abrasive matter to an intermediate stage of the pump. The conduit 47 leads from the pump discharge 41 to a purifier 48 which may be of the cyclone type, a filter or a centrifugal purifier fitted on the pump shaft. Part of the purified liquid is passed through conduits 49, 34 and constricted space 31 to a balancing device 28. The discharge from the device 28 passes through a bearing 21 and a restriction 23 to a conduit 62 leading to a chamber 54 at the inlet end of the pump. From the chamber 54 the purified fluid passes through a restriction 13 and the bearing 12 to a space 18 which leads the fluid back to the pumping channel after the first stator blade stage. A further portion of the purified liquid is fed through conduits 55, 39 to the intermediate bearings 38. The muds and heavy abrasive matter segregated from the liquid flow through the conduit 51 to the chamber 42 arranged after the rotor blades 6. A pump 36 is arranged to prevent leakage of the fluid being pumped to the balancing device 28. A device 56 is provided to supply clean liquid to the bearings and balancing device during starting.

Title: Improvements in or relating to a method for producing ferritetracemic acid
IPC: C07F15/02
Filed: 1961-04-27
Abstract: The ferric chelate complex of ethylenediaminetetracetic acid ("ferritetracemic acid") is prepared by reacting ethylenediaminetetracetic acid with a ferric sulphate solution at elevated temperature, and removing the sulphuric acid formed, e.g. by the addition of a precipitating agent, such as barium carbonate or calcium carbonate, or by passing the reaction mixture through a highly cross-linked weakly basic anion exchange resin of the polystyrene type.  Ferrous ferritetracemate is prepared by using barium carbonate as precipitating agent in the foregoing process, removing the precipitated barium sulphate, reacting the resulting barium ferritetracemate solution with ferrous sulphate at elevated temperature under an inert atmosphere, filtering off the precipitated barium sulphate and evaporating the filtrate to dryness.  Medicinal compositions, consisting of or containing pure ferrous ferritetracemate prepared as above, are effective in the treatment of anaemia, chlorotic conditions, ataraxia and asthaenia by oral ingestion.

Filed: 1920-06-12
Abstract: 172,345. Brougham, F. J., (Vapor Car Heating Co., Inc.). June 12, 1920. Fluid-actuated valves. - In a heating system for railway carriages and the like, the supply of steam or other heating medium is increased or decreased according to whether the signalling or other apparatus, which is connected up when the carriages are assembled, is in or out of action. Valves in the steam supply pipe of the radiators are maintained in their open position by the air pressure in the train pipe of the signalling system. The steam valve 25, Fig 2, may be set in half-open position by depressing a handle 42, which causes a lever 44 to engage with a lip on a sleeve 37 secured to the valve spindle so as to prevent the valve from being closed by the upward pressure of a spring 30. When air pressure is admitted above the piston 28, the steam is fully opened. and the lever 44 is withdrawn by a spring 49 from engagement with the sleeve on the valve spindle. A port 27 allows a small quantity of steam to pass to the radiator when the valve is closed. The supply of steam to the main and auxiliary radiators K, L, Fig. 3, is controlled for a four-way valve 84, operated by piston device 98 connected to the air-pipe M of the signalling system. A lever 95, Fig. 4, pivoted to the en'd of the piston-rod 96 rotates a member 93 having lugs adapted to engage in slots in a disc 90 on the end of the valve member. The valve may be operated by hand by raising it against the pressure of a spring 87 out of engagement with the lugs. The steam supply to the main radiator passes through a hand-operated valve 83.

Title: Improvements in and relating to valve construction
IPC: F16K15/14
Filed: 1944-08-22
Abstract: 610,508. Non-return valves. BURKE, O. J. Aug. 22, 1944, No. 16025. Convention date, Oct. 20, 1943. [Class 135] A non-return and venting valve for liquid systems comprises a valve member of flexible material such as natural or synthetic rubber arranged between the inlet and outlet ends of a casing having an air port, the valve member being sealed to the casing between the air port and the inlet end and coacting under internal pressure with a succession of seals between the air port and the outlet end to effect multiple sealing off of the air port. As shown, the valve member 40, Fig. 1, is of deep cup-like form, anchored at its open end to a rigid containing casing 10, preferably of brass or other metal, and provided at its closed hemispherical end with radial self - closing slits 44, Fig. 3, strengthened by moulded ribs 50. Liquid flow from the inlet 16 passes through the slits 44 to the outlet 13, distending the member 40 and causing it to coact externally and, as the pressure increases, successively with a convex valve seat 10b, a concave seat 10a, a rib 42 and a cylindrical seat 10c thus sealing the flow passage off from the air ports 28 in the casing wall. A rigid sleeve 32 prevents the distended member 40 from fouling the ports 28, which are also protected externally by the forward extension 29 of a screwed inlet coupling 15. On loss of pressure in the liquid supply system, the slits close, preventing reverse flow, whilst the valve member retracts from its sealings and allows air to enter the discharge side of the liquid system. In Fig. 1 (not shown), the threaded outer end of the inlet coupling is dispensed with, the valve member being extended outwardly to form an elastic inlet nipple connection.
