Title: Process for producing fertilisers
IPC: C05B13/02
Filed: 1936-02-22
Abstract: A fertilizer is obtained by calcining raw phosphate with lime and silica at temperatures up to about 1450 DEG  C., the proportions of the ingredients being such that the product of calcination contains about 58--65 per cent of CaO, about 15--25 per cent of P2O5 and about 15--25 per cent of SiO2.  The product contains the compound 9CaO.P2O5.3SiO2 or the compound 16CaO.2P2O5.5SiO2.  When the process is conducted in a rotary furnace no snitering occurs and a non-caking loose powder is produced even when fluorine-bearing raw phosphates are used.  The lime may be added as calcium carbonate or limestone, or any compound forming lime on calcination and the silica may be added in the form of sand &c. Calcium silicate or slags chiefly consisting thereof may also be used.  Raw phosphates rich in lime and silica may be used.  The calcination is preferably effected in an atmosphere of steam.  The Specification as open to inspection under Sect. 91 comprises also the replacement of the silica in part by alumina or ferric oxide and the replacement of the lime in part by magnesia.  This subject-matter does not appear in the Specification as accepted.ALSO:A fertilizer is obtained by calcining raw phosphate with lime and silica at temperatures up to about 1450 DEG  C., the proportions of the ingredients being such that the product of calcination contains about 58-65 per cent of CaO, about 15-25 per cent of P2O5, and about 15-25 per cent of SiO2.

Title: Improvements in the manufacture of copper alloys
IPC: C22C9/00
Filed: 1936-02-25
Abstract: Copper alloy castings are produced by adding 0,2-2,0 per cent of chromium to the copper with or without suitable deoxidants, casting the alloy and then heating the casting to 300-700 DEG  C.  The deoxidants employed are zinc-sodium alloy, cadmium sodium alloy or one or more of the substances calcium, silicon, beryllium, calcium boride or boron carbide and the metal may be covered with charcoal or a flux such as borax or glass during melting and casting.  The chromium may be added to the copper in the form of a master chromium-copper alloy containing 10 per cent of chromium and one or more of the metals, lead, silver, zinc and cadmium in a total amount not exceeding 5 per cent may be added to the alloy before casting. In an example, an alloy contains in addition to the chromium content above 1 per cent of cadmium, 1 of zinc, 0,5 of lead and 0,10 of silver.  The alloy castings may be used for the manufacture of electrical devices such as plugs, &c., casting moulds, parts of internal-combustion engines and twyers or other fittings of blast furnaces.

Title: Improvements in or relating to means for priming centrifugal pumps
IPC: F04D9/04
Filed: 1931-02-23
Abstract: 361,215. Priming rotary pumps. PULSOMETER ENGINEERING CO., Ltd., and BJÍRNSTAD, J., Nine Elms Iron Works, Reading. Feb. 23, 1931, No. 5653. [Class 110 (i).] A rotary exhauster of the water ring type is employed for the purpose of priming a centrifugal pump ; the exhauster is driven from the pump shaft and is provided with a water jacket, the water from which gradually replaces that in the water ring thereby keeping the water ring cool. The centrifugal pump 28 is shown in Fig. 4 on a vertical shaft 29, and the exhauster is enclosed in two abutting casing parts 11, 12. These two parts form the water jacket and are connected by passages 13. The shaft 15 carries the rotor 16 working in a casing 14 inside the jacket, and the bearing sleeves 17 in which the shaft runs have longitudinal grooves connecting with annular chambers 19 on each side of the rotor boss. Radial grooves lead from these chambers 19 to the suction ports 22. The water from the jacket is drawn through the grooves into the water ring of the exhauster; a corresponding quantity is discharged from the ring through the discharge ports 22a into the jacket. The :whole liquid contents of the jacket and the exhauster are thus kept circulating. A funnel 23 with a strainer plate 24 is placed at the top of the exhauster for the purpose of filling the jacket. When this is accomplished. the funnel is turned downwards to close the cock 25. The shaft 15 is in two parts connected by a coupling 32, Fig. 4, and the part remote from the exhauster rotates in a long sleeve the end of which forms one-half of a friction clutch ; skew gearing connects this sleeve to the shaft 29 of the main pump 28. The other member of the friction clutch is keyed to the shaft 15 and has a grooved boss to receive a collar operated by the hand-wheel 39. In a modification the filling apparatus comprises the branch piece 44, Fig. 8, which is included at the highest point of the suction pipe of-the main pump 28. A float 45 operates the valve 46 controlling the entrance to a chamber 47 connected to the suction passage 26 of the exhauster by a pipe including a check valve. The exhauster draws air from the main pump suction through the valve 46 and the suction pipe 26, and when the main pump 28 is fully primed the float 45 closes the valve 46. A small byepass round the valve permits the escape to the exhauster of any air which may collect in the main suction pipe. In the modification shown in Fig. 10, the shaft 15 of the exhauster is connected by skew gearing to the extension 56 of a friction clutch member 35 free to rotate on the sleeve 57 driven by the main pump spindle 29. The other clutch member 58 rotates with the sleeve but can be moved axially upon it by means of a forked lever 61 operated by a hand-wheel 64. The clutch is submerged in oil, but the shaft 15 and the spindle of the hand-wheel 64 are placed above the oil level to avoid leakage through their bearings.

Patent GB-773075-A (GB)
Title: Improvements in or relating to apparatus for reading information stored in electronic storage tubes
IPC: H01J31/58
Filed: 1954-02-26
Abstract: 773,075. Electric digital-data-storage apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 26, 1954 [Feb. 27, 1953], No. 5821/54. Class 106 (1). [Also in Group XL (a)] A secondary-emission multi-anode tube, Fig. 3, having a voltage current characteristic, Fig. 4, has a control grid g1, accelerator and collector grids g2, g3 connected to a constant positive potential source k, and is arranged in a circuit in which each anode has a load Ra connected to earth potential. When so arranged the load line Ra, Fig. 4, intersects the anode characteristic in three points giving the stable conditions O and C in one of which the anode must be, and thus each anode can store one binary bit. The manner in which the anode is caused to assume either one of these conditions, i.e. data entry, is not described. If an anode is in the " high " voltage condition, point C, Fig. 4, and the primary electron flow from the cathode is stopped, its potential begins to fall along the line Ra as condenser C, Fig. 3, discharges through the resistors Ra and Ral in series, resistor Ra1 being chosen considerably smaller than Ra. Ultimately, the potential of the anode would fall to zero, but if before this happens, for example when the anode is at point A, the primary electron flow is restarted, then the momentarily effective anode load is resistor Ra1, being the effective impedance of the circuit comprising condenser C and resistor Ra1 in series and both paralleled by resistor Ra, to a pulse ; the effective load line is thus Ra1 and since the anode potential must be on both the load line and the characteristic it suddenly runs along load line Ra1 to point B producing a signal U across the resistor Ra1. Condenser C will then gradually charge and as the effective anode load increases to Ra the anode potential will return to point C. Thus by temporarily suppressing the primary electron flow from the cathode for a suitable period an output indication of the condition of the anode is produced across resistor Ra1-the output signal being a positive pulse if the anode is in its "high" condition or no pulse if the anode is in its " low " condition. In the preferred embodiment a stream of positive pulses is applied to the control grid of the tube, consecutive pulses being so timed that anodes in condition C do not fall below condition A, and a number of such tubes are coupled so that condenser C and resistor Ra1 form a common output circuit for corresponding anodes. Also in this embodiment, the pulse trains to successive tubes are successively out of phase so that only one tube begins to conduct (i.e. the primary electron flow restarts) at any one instant. In this way the output pulses appearing across any one resistor Ra1 will represent in serial form the date stored on the corresponding anodes. Further, in this embodiment, to improve resolution the grid pulses have their leading edges peaked, and resistor Ra1 is replaced by an inductance shorted by a diode. Specification 773,076 is referred to.
