Title: Determination of heavy metal ion concentrations
IPC: G01N27/42
Filed: 1976-09-17
Abstract: 1522410 Determining heavy metal ions electro-chemically SIEMENS AG 17 Sept 1976 [25 Sept 1975] 38739/76 Heading G1N Heavy metals in aqueous liquor are determined by conducting the liquor for a predetermined length of time and at a constant flow-rate past a solid electrode maintained at a negative direct voltage to deposit heavy metal thereon, replacing the liquor by an electrolyte and the negative voltage by a positive direct voltage and determining the charge to remove any deposited heavy metal from the electrode. The negative voltage may be - I to -4V preferably - 1À5 to -2À5V, and the predetermined length of time 1-10 minutes. The positive voltage may be 0À5 to 3V preferably 0À8 to 2V. The electrolyte is preferably sodium chloride or sodium sulphate of concentration 10<SP>-1</SP> to 10<SP>-3</SP> mol/litre and pH 1 to 7 preferably 3-4, and is preferably stationary during the dissolution. Apparatus for carrying out the determination comprises a measuring cell 24 with working electrode 25, and counter electrode 26 and gas riser pipe 29. The aqueous liquor is supplied via filter 20, and constant head device 21 and valve 22 and the electrolyte from tank 31 via valve 32. A valve is provided in the cell outlet so that the aqueous liquor can flow through the cell during the deposition period but the electrolyte does not flow during the dissolution. A control circuit for the valves and voltages and means for integrating and displaying or recording the dissolution current and generating an alarm if a predetermined heavy metal concentration is exceeded, are provided. The deposition may be conducted with the working electrode stationary or moving i.e. rotating or vibrating. The liquid in the cell may be mechanically circulated. The electrodes preferably have an area of about 20 mm<SP>2</SP> and are preferably rods and of platinum; graphite, glass-carbon and carbides being alternative materials. The counter electrode is preferably of larger area than the reference electrode. In alternative embodiments the electrodes may be coiled wires; the counter electrode a coiled wire surrounding a rod working electrode, the counter electrode a cylinder surrounding either a cylinder or a rod working electrode or they may both be cylindrical and set in the walls of a ceramic, glass or synthetic plastics tube. The method and apparatus may be used for the automatic monitoring of heavy metal pollution. The method has a detection limit of about 10<SP>-6</SP> equivalent/litre.

Title: Method and apparatus for producing emtallic articles by electro slag melting
IPC: C22B9/18
Filed: 1973-08-16
Abstract: 1451924 Continuous casting MITSUBISHI JUKOGYO KK 16 Aug 1973 [28 Aug 1972] 38860/73 Heading B3F Consumable electrodes 1, having a total cross-sectional area greater than that of the metal of an article M cast therefrom in a mould 2, are fed into a slag bath S in a portion 3 of the mould, heated by non-consumable electrodes 5 as well as the electrodes 1 to be melted to form a molten pool 4, mainly in a mould portion which has a greater volume per unit height (because of diverging wall portions as shown) than the volume per unit height of the casting cavity of the mould. The electrodes 1 may be in radially-adjacent pairs. The mould 2 is water-cooled and as shown is annular, consisting of an outer ring 2a around a ring 2b, to cast a tubular body M. Pressure vessel bodies or solid bodies may be cast. To collect non-floating impurities from the slag bath S, a groove (11) may be formed in each level portion which extends between the sloping sides of the bath portion 3 and those of the part containing the molten pool 4. Separately-prepared molten slag is poured into the bath portion 3 at the beginning. The increased heating, by the non-consumable electrodes 5, is said to provide an increased casting rate and since the electrodes 5 may be moved horizontally, e.g. oscillated horizontally, with or without the electrodes 1, the heating is more uniform and powdered slag can be added without lowering of the temperature of the bath S. A slag film 10 is formed on each side of the casting M to improve the surface. The electricity supplies to 8, 9 to the consumable electrodes 1 and the non-consumable electrodes 5, respectively, are each connected to a casting starter 6 supported by raising and lowering means 7.

Title: Improvements in or relating to magnetic storage and switching apparatus
IPC: H03K17/82
Filed: 1958-12-15
Abstract: 896,967. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 15, 1958 [Dec. 18, 1957], No. 40334/58. Class 38 (2). [Also in Groups XIX and XXXIX] A core 10 (Fig. 2), which acts as a switching or storage device for logical functions, having a rectangular hysteresis loop, may be moulded, cut from a sheet or formed as a film, and has a central aperture 12 linked by hold winding 18 and surrounded by selection aperture 13 and signal apertures 14, 15 and 16, the former being linked by select winding 26 (or by two half-select windings) and the latter by drive and output windings such as 30 and 32 as shown for aperture 15. Instead of being provided with apertures, the core may be moulded around the conductors. The core is set in the OFF position with its remanent flux clockwise by a full select pulse through winding 18 (Fig. 3, not shown). An oppositely-directed half-select pulse in winding 18 assisted by an appropriately-directed half select pulse in winding 26 then reverses the local flux surrounding select aperture 13 to an anticlockwise direction (Figs. 4A and 4B, not shown). The core is then ON and the application of a suitable pulse to a drive winding, e.g. 30, linking one of the signal apertures 14, 15, 16 produces local reversal of the flux surrounding that aperture to an anticlockwise direction, thus producing an output in sense winding 32. The output may be used to show that a binary zero was stored at aperture 15, or to indicate the application of the drive pulse or may be ignored. Application of a reset pulse to drive winding 30 produces an opposite output pulse in winding 32 which can be used to indicate the earlier application of the drive pulse, or that a binary 1 is stored at aperture 15 or can be ignored. The core may be used as a master switch which must be turned ON so that the signal apertures can be used as individual switches to cause an input signal to produce a signal in an output circuit. In the switching to ON of the core, windings 18 and 26 can be used as an AND circuit. A number of signal apertures may have a common output winding to perform an OR function. The flux round an aperture may be switched by a combination of drive inputs to perform an AND function. The core may be rectangular and have rectangular apertures (Fig. 6). The core may have one or more read windings 102 (Fig. 8) linking the individual signal apertures 93 instead of resetting pulses in the drive windings 100 being used for this purpose. The coincident application of pulses to two or more read windings linking a signal aperture can then be used to perform AND functions. The windings linking the signal apertures may be of figure-eight type.

Class 98 (2). A silver image is formed on a metal support, the surface of which has been grained, anodized or converted to a compound of the metal to render it hydrophilic preferably without the use of a colloidal binder by the silver salt diffusion process in the presence of an organic compound containing in the molecule a strongly oleophilic group and another group which has an affinity for silver and becomes integrated to the silver image but not to the metal or metalcompound surface, to produce the printing plate. In Example 1 a washed and diluted Carey Lea silver sol is applied to an anodized aluminium sheet, the image is transferred thereto from a high contrast chloride emulsion using 1 - hexyl - 1,2,4,5 - tetrahydro - 1,3,5 - triazene- 4-thiol in the transfer-developer and is wiped over with gum arabic before inking. Example 2 uses similarly the corresponding 1-octyl triazine derivative, and Example 3 describes the coating of anodized aluminium with a solution of hypo and potassium octyl xanthate for image transfer without the use of nuclei. Numerous other organic sulphur compounds for the purpose are quoted. Specifications 934,692 and 934,693 also are referred to.
