Title: Ladle and method for the treatment of molten metals
IPC: B22D1/00
Filed: 1954-11-15
Abstract: Treatment of molten metals by gases, e.g. for stirring or refining the metal, is effected in a ladle having a refractory lining, the bottom of the ladle comprising a porous portion substantially flush with the rest of the bottom lining, the ratio between the ladle depth at its normal filling level and the ladle's inner diameter at the said levels being between 1 and 1.8 and the relation between the porous area s and the area S of the ladle inner section at its normal filling level being such that 0.32 log S + 0.39 < log s < 0.67 log S-0.14 the base of the logarithms being decimal and S and s being expressed in square centrimetres.  The porous portion is preferably a removable silicon carbide plug which may be sealed to the ladle lining by a chromium oxide base cement containing a small amount of bentonite and sodium silicate.  The plug preferably has a porosity such that 50-200 litres of air pass, at room temperature and normal pressure, per minute per square decimetre of exposed porous area per kilogram per square centimetre of upstream pressure.  Molten ferrous metals may be desulphurized by first charging a desulphurizing slag, e.g. blast furnace slag, in the solid state, then charging molten metal while blowing gas through the porous plug.  Molten steel may be deoxidized by adding a small amount of carbon to the molten steel and blowing in an inert gas to disperse the carbon and lower the partial pressure of carbon monoxide as it is formed.  Silicon may also be removed by blowing in an inert gas.  Reference is also made to the incorporation in molten metals of highly reactive agents such as magnesium and/or boron, dispersion of the agents being rapidly effected by blowing in argon or helium.  Reference has been directed by the Comptroller to Specification 671,678.

Title: Separating apparatus
IPC: B04C5/28
Filed: 1970-07-08
Abstract: 1,272,387. Cyclone separators. BATTELLE DEVELOPMENT CORP. 8 July, 1970 [9 July, 1969], No. 33231/70. Heading B2P. An apparatus for separating a suspension of solid particles into at least two fractions of different densities comprises one or more cyclones C 1 -C 4 , Figs. 1 and 2, secured for rotation with a rotary housing 4 A-C and communicating via its inlet with the housing interior 4, 5 to which the suspension is fed. Feeding of the suspension takes place through a conduit 7 and a hollow belt-driven shaft 1 connected to the housing. The cyclones are surrounded by a spiral trough 8 formed with two channels 8A, 8B for respectively collecting the heavier and the lighter of the separated fractions which are discharged from the cyclones respectively through their apical underflow outlets and through siphons S 1 -S 4  connected to their overflow outlets. Fins 4B which secure together the parts 4A and 4B of the housing serve to provide a radial and angular acceleration to the incoming suspension before its passage through the cyclones. Each cyclone and its siphon may be provided at their radially outer ends with nozzles such as t a  and t b  oriented in a direction opposite to the direction of rotation F of the housing so that as the heavier and lighter fractions are discharged from the cyclones they produce a reactional force on the cyclones and on their siphons that helps to drive the housing in the direction F. The housing may be fed through a flexible tube instead of through the hollow shaft 1. In a modification Fig. 5, the rotary housing E, is connected to cyclones k 1 , k 2  and k 3  arranged in series and having separate over flow syphons S 1 , S 2  and S 3 . In a further modification, Fig. 6 (not shown), the cyclones are connected in series via their overflow syphons and have separate underflow outlets.

Title: Improvements in or relating to alternating current electric meters, instruments, relays or the like
IPC: G01R11/36
Filed: 1938-11-17
Abstract: 521,555. Supply meters; current and voltage measurements. RICHARDSON, T. C. Nov. 17, 1938, No. 33378. [Class 37] A meter, instrument, or relay is combined with a transformer comprising a core 7 having predetermined magnetic properties, a primary winding 9 traversed by the main current, and a secondary winding 8a for supplying an extra current which is added to or subtracted from the main meter current. As shown the series coil 2 of the driving magnet 1 is connected in series with the transformer primary winding 9 across the instrument terminals 3, 4, and the secondary winding 8a is connected in shunt across the series coil 2 in series with an adjustable resistance 5, 6. The transformer core 7 is of a material and section such that it saturates at a lower value than the full load current, e.g. 30 per cent. to 50 per cent. of full load. It may comprise laminations of different magnetic materials which reach saturation point at different values of the magnetising force. At loads above 50 per cent. of full load the secondary winding 8a acts as a shunt and reduces the effective current in the meter coil 2. At lower loads the current in the coil 2 is increased beyond the normal value. The response curve of the modified instrument is stated to be substantially linear from full load to 10 per cent. of full load. In a modification the primary winding 9 is connected to the meter terminals 3, 4, the secondary winding 8a being connected in series with the meter coil 2 and resistance 5, 6. Alternatively the secondary winding 8a may supply a supplementary coil on the core 1 of the meter magnet. The primary winding of the transformer may be constituted by the main coil 2 of the meter. A three-phase KVA maximum demand indicator of theinduction meter type is described in which each of the three driving magnets has associated with it a transformer arranged as shown. The' transformers are carried by brackets on the meter base between the lower driving magnets and the terminal strip, so as to come within the cover.

Filed: 1949-12-30
Abstract: Highly adsorbent and water-absorbent artificial fibres are obtained by incorporating in a spinning solution finely divided activated charcoal which has been impregnated with an alkali-stable emulsifying agent, and then extruding the solution and forming fibres therefrom. The activated charcoal may be incorporated in viscose, cellulose acetate solutions or other cellulosic solutions.  The alkali-stable emulsifying agent may be a poly-galacturonic acid, a saponin or a polyhydric alcohol.  The proportion of activated charcoal incorporated in the spinning solution may be up to 10 per cent. by weight based on the filament-forming substance.  The fibres so obtained may be used for making bandage materials.  The Specification as open to inspection under Sect. 91 comprises also the production of artificial fibres from spinning solutions which contain silica gel or which contain water-glass.  In the latter case a coagulating bath containing sulphuric acid is employed, whereby silica gel is deposited in the fibre during its production.  The use of an emulsifier is not essential.  This subject-matter does not appear in the Specification as accepted.
