Title: Improvements in or relating to full-wave rectifying circuits
IPC: H05B44/00
Filed: 1963-09-03
Abstract: 984, 856. Photo-electric full-wave rectifying circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 3, 1963 [Sept. 24, 1962], No. 34676/63. Heading G1A. In a full-wave rectifying circuit input from an A.C. generator 1 is applied through a transformer 2, 3 to circuit input terminals 3a and 3b. Each of these terminals is connected to the secondary winding centre-tap 3c through a photo-emissive device 4a, 4b, which passes current, and emits light only during alternate half-cycles. The two devices are effective alternately and the light from them falls respectively on photo-conductive devices 5a and 5b connected respectively to terminals 3a and 3b and jointly to output terminal 7. The second output terminal 8 is also connected to the centre tap 3c and a filter circuit 6 may be provided to smooth the output. In operation during one half cycle of the input waveform photo-emissive device 4a is illuminated and light from it falls on photo-conductor 5a enabling current to pass from terminal 3a to output terminal 7. In the following half cycle device 4a is extinguished and device 4b illuminated so that photo-conductor 5a has a high impedance and 5b a low one thus allowing current of the same polarity as in the previous half cycle to pass from terminal 3b to terminal 7. The devices 4a and 4b may each comprise a diode and a neon tube connected in series. The neon tubes may be replaced by electroluminescent phosphor elements. In a modification (Fig. 3) the neon 11 in unit 4a also illuminates photo-conductive device 19 which is in parallel with the neon 18 in device 4b. This neon is not associated with a diode but is, by the means, prevented from lighting except on the half cycles when neon 11 is not lit. Devices 4a and 4b may also comprise photo-emissive unidirectionally conducting units such as gallium arsenide or gallium phosphide diodes.

Title: Improvements in or relating to the removal of bases from water
IPC: B01J39/16
Filed: 1935-12-14
Abstract: To remove bases from water, particularly water which has been softened by any of the ordinary processes and contains alkali metal salts, the water is brought into contact with humic material, such as peat, lignite or coal, which has been treated with a dilute acid in such manner that it has absorbed hydrogen ions and has lost acid soluble bodies but is otherwise chemically unchanged.  Mineral acids, such as sulphuric acid or hydrochloric acid, or weak organic acids, such as acetic acid, may be used. The raw material may be initially mixed with a bonding material, for example sodium silicate, formed into briquettes, nodules or grains and baked at a temperature of 200 to 300 DEG  C. or treated with steam at a temperature of 100 DEG  C. It may also be stabilized by treatment with salts of trivalent metals, such as iron, aluminium or chromium.  The process of stabilizing by means of chromium salts as described in Specification 451,899 may be used. The material is granulated for use and after use may be regenerated by treatment with dilute acid.  To obtain a water containing sulphates only, water which has been treated with the humic material may be mixed with softened water containing carbonates in such proportions that the acid neutralizes the carbonate.  A water containing sulphates can also be obtained by using humic material treated with acid containing common salt.  A water containing calcium sulphate can be obtained by mixing water which has been softened by means of the humic material with hard water containing calcium carbonate.  Reference has been directed by the Comptroller to Specification 450,575.

Title: A method of grinding, utilizing a continuously operating automatically self-regulating wet grinding process
IPC: B02C21/00
Filed: 1955-12-09
Abstract: 798,100. Web grinding; washing granular materials. DORR-OLIVER, Inc. Dec. 9, 1955 [Dec. 17, 1954], No. 35389/55. Classes 59 and 82(2) A continuous method of grinding utilizing a continuously operating closed wet grinding circuit is characterized by feeding from a distribution tank 10 to a hydrocyclone separator 34 a slurry of carrier liquid and particles to be ground, whereby the solids are classified into a final predominantly fine fraction discharging at the overflow 36 of the hydrocyclone and a coarser underflow fraction which is fed at 38 to the grinding station 42; recycling the discharge from the grinding station as feed to the hydrocyclone whereby still oversize particles are returned to the grinding station; and controlling the degree of fineness of the solids in the said overflow by controlling the dilution of the slurry in the tank 10. Solids are introduced at 12, water at 14 and re-circulated solids from the rod or ball mill 42 at 16, a float 22 actuating a throttle 18 to the water supply. A pump 28 delivers slurry from the tank 10 to the hydrocyclone or battery of hydrocyclones 34 viaa throttle 32. Solids may also be added direct to the mill at 13. To vary the mesh of separation at the cyclone the flow of slurry is adjusted either by means of the throttle 32 or preferably by varying the pump speed and using 32 as a fine adjustment. The pump rate may be adjusted by means of a variable sheave belt drive 54, 50, 52; or by varying the speed of the motor 46 as by a rheostat 49 fed by a generator 48. Reducing the flow of slurry results in decreasing the mesh of separation (increase in the diameter of particle size at which separation in the cyclone occurs), since the level H tends to rise and actuate float 22 and valve 18 to reduce the water input, so maintaining the level H and increasing the solids concentration led to the cyclone. Increased flow of slurry to the cyclone similarly increases the mesh of separation. The dilution of slurry is preferably controlled to maintain in the underflow 38 a liquid to solids ratio by volume of between 1.5 : 1 and 1 : 1.
