Title: A method for treating molten metal
IPC: F27D27/00
Filed: 1956-06-11
Abstract: 801,156. Refining metals; iron manufacture. STORA KOPPARBERGS BERGSLAGS AKTIEBOLAG. June 11, 1956 [June 15, 1955], No. 17958/56. Classes 72 and 82(1) Molten metal is treated in a vessel 7 by moving the latter without rotation about its own axis along a substantially circular path with respect to a vertical axis, controlling the speed of the vessel so that the molten metal performs a circular motion within and relatively to the vessel, and adding a treating (e.g. refining): agent to the metal. Refining of crude iron, steel, and non-ferrous metals is referred to; particularly the treatment of crude iron with pulverized lime or sodium carbonate to desulphurize it, with slags rich in ironto dephosphorize it, and with oxygen or oxygen - enriched air. In the apparatus shown, a table 5 rotated via shaft 8 and bevel gear 25 is mounted on roller bearings 21, the lower race of which is fixed to the base 20, and is coaxial with the stub shaft 4. An annular disc 2 rests on table 5, its. axis B being eccentric with respect to the axis A of shaft 4, and the degree of eccentricity being adjustable by rotating; a ring 3 having outer and inner peripheries mutually eccentric and in contact respectively with the outer periphery of boss 22 and the inner periphery of disc 2. An upper table 1 is supported on disc 2 by roller bearings 28 concentric with the axis B and carries the ladle 7 containing molten. metal for treatment. The table has a lateral extension 26 presenting a radial keyway in which works a key 6 pivoted to the part 27 rigid with the base 20. In operation the vessel 7 performs a circular motion due to the eccentricity of the disc 2 and table 1 but does not rotate due to the key 6. The axis B rotates about axis A; the axis of the vessel (which is slightly to the right of B as seen in the drawing) also rotates, the movement of the vessel about its own axis being confined to a slight angular oscillation. The treating agent may be added to the metal melt prior to or during the movement of the vessel. Specifications 665,258 and 677,349 are referred to.
Patent GB-397933-A (GB)
Title: Improvements relating to electric discharge tubes, and particularly luminous gas-filled tubes
IPC: H01J61/28
Filed: 1932-03-11
Abstract: 397,933. Discharge apparatus. SCHALLREUTER, W. L. W., 73, Cambridge Terrace, Hyde Park, London. March 11, 1932, No. 17975/31. [Class 39 (i).] In order to prevent hardening, a gas-filled tube, such as a lamp, has a stream of gas or vapour added to the discharge space, and the added gas &c. is such as to be subjected by the discharge to a chemical change to form the filling or one or more constituents of the filling, and an absorbent, in communication with the tube, takes up the excess of unchanged gas &c., particularly when no discharge is taking place, but does not take up gas &c. changed by the discharge. The substance evolving the gas &c. is connected with one part of the tube and the absorbent with another part. In one example, a tube has a side branch containing calcium carbonate evolving carbon dioxide. During the discharge carbon dioxide is decomposed in the presence of a catalyst such as silicon on an electrode, forming carbon monoxide giving the luminous discharge and oxygen which is absorbed by the electrodes, preferably of aluminium or magnesium, or by red or white phosphorous, or alkali or alkaline-earth metal. A second side branch contains caustic potash which absorbs carbon dioxide but not carbon monoxide. In another example, the filling consists of neon with traces of hydrogen. The first side branch contains calcium or magnesum chloride, or phosphoric acid saturated with water, and the absorbent in the second side branch is a drying agent such as phosphorus pentoxide. Under the action of the discharge, water vapour is decomposed into hydrogen and oxygen which is cleaned up by iron electrodes. A ripple or wriggling effect may be produced in a tube containing at least three gases ; for example a tube containing a main filling of neon has side branches evolving water vapour and carbon dioxide. The discharge is confined to the main filling of neon, and avoids the carbon monoxide, thereby producing ripples. The proportions of gas may be maintained by using one or two absorbents. Or a discharge may be obtained in which all the gases are luminous, but are separated along the tube in the form of discs or beads. Tubes containing neon with traces of sulphur vapour, and nitrogen with traces of carbon monoxide are also referred to.

Title: Improvements in and relating to the manufacture of artificial structures
IPC: D01F2/08
Filed: 1935-12-27
Abstract: Artificial threads, films, dressings, finishings, printings, cements, adhesives, plates and artificial structures in general are made from viscose in the preparation of which a proportion of carbon disulphide not smaller than 20 per cent is used, by employing for the coagulation of the shaped structure a secondary alkali carbonate. In the preparation of the viscose, there may be used 25--30 or 40--50 parts of carbon bisulphide relative to 100 parts of cellulose; the alkali cellulose may be allowed to mature for a longer or shorter time; the temperature, particularly during the dissolution step, may be below 0 DEG C., even below -10 DEG C., as described in Specification 212,865, [Class 2 (ii)]; and the viscose may be allowed to mature before use, say to beyond the C24 or C36 stages. An aqueous solution of secondary sodium carbonate is the preferred coagulation bath; and the bath may also contain a salt of alkaline reaction such as dibasic or tribasic alkali phosphate, an alkali borate, silicate, thiosulphate, acetate, &c. or a neutral salt such as alkali sulphate or chloride, and an organic substance such as glycerine, a sugar or turkey red oil.  The secondary alkali carbonate may be used as the primary coagulation bath; or the structure may be preliminarily coagulated in a bath of, say ammonium sulphate or chloride, acid sodium silicate, sodium bisulphite, methanol or ethanol, and afterwards the coagulation completed in the secondary alkali carbonate bath.  The coagulated product may be washed with water, or it may be treated, with or without washing, with a bath containing an acid or a neutral acid or alkaline salt or with another bath capable of coagulating viscose etc.; or, alternatively, the product may be first treated with a cold, warm or hot solution of a primary or secondary alkali carbonate. The secondary alkali carbonate may be reconstituted in the coagulation bath by introducing carbon dioxide.  Specifications 25246/11, [Class 2 (iii)], 281,352, 312,197, 319,293, 323,731, 323,732, 323,747, [all in Class 2 (ii)], 341,899, 390,517, 408,932, and 408,950 also are referred to.

Title: Improvements in or relating to ward-leonard motor control systems
IPC: H02P7/34
Filed: 1949-07-08
Abstract: 690,928. Automatic speed control systems; inductors. GENERAL ELECTRIC CO., Ltd., and SCOTT, P. July 10, 1950 [July 8, 1949], No. 18163/49. Classes 38 (ii) and 38 (iv). [Also in Group XXXVII] In a Ward-Leonard motor control system the speed of the motor 10 is controlled in accordance with the difference between a reference voltage developed across a potentiometer 30 and a voltage proportional to the speed of the motor, an over-riding control being provided to prevent the current in the generator 12 exceeding a predetermined value. The voltage proportional to motor speed is also proportional to the voltage across the motor or generator and is fed via a rectifier arrangement 35 to control a field winding 20, to which the reference voltage is also applied, of a pilot generator 13 having anti-hunting windings 21, 22. The pilot generator 13 controls an excitation generator 14 controlling the main generator field winding 15. Connected in series with the motor 10 and generator 12 are control windings 50, 51 associated with saturable reactors 52, 53 respectively which are also provided with bias windings 54, 55. The reactor may be either of the three- or six-phase type. The output of the reactors is fed to rectifier arrallgements 72, 73 and the output from these compared with a reference current derived from rheostats 78, 79. Owing to the action of rectifiers 80, 81 no current is fed to the field winding 20 unless the value of the rectifier output exceeds the reference current due to excessive generator 12 current flow, when the resultant current acts on the field winding 20 in a sense to reduce the generator current. In a modification the motor speed proportional voltage may be derived from a tachometer generator coupled to the motor 10. The reactors may be constructed as shown in Fig. 2, comprising two three-leg cores 60, 61, the legs carrying the phase windings of which only 65, 65<SP>1</SP> are shown, a yoke member 62 carrying control windings 50, 51 and a bias limb 64 carrying the bias winding 54, 55. The reactors may be constructed separately, Fig. 3 (not shown). In a further modification the current limiting arrangement may comprise four saturable reactors, each provided with an additional control winding carrying a reference current, the reactors being arranged to form two balanced pairs, each pair giving an output current proportional to the difference between the generator current and reference current.

Title: Improvements in or relating to the production by spinning of regenerated cellulose filaments
Inventor: STUDER MARTIN
IPC: D01F2/06
Filed: 1951-07-31
Abstract: Filaments, ribbons and foils are formed by spinning a viscose solution having a gamma number above 60 into a bath of low electrolyte content at room temperature, the regenerated cellulose having a degree of polymerization above 300, the filaments, &c., being stretched continuously with their formation in such a way that the speed of travel after stretching is not greater than 12 metres per minute.  The gamma number is defined as the number of mols of carbon bisulphide combined per anhydro glucose radical multiplied by 100.  The spinning bath comprises per litre between 10 and 40 grams of sulphuric acid and up to 100 grams of sodium sulphate with no other metal salt but optionally with the addition of lauryl pyridinium chloride or sulphate.  In making the cellulose xanthate, material containing cellulose of high molecular weight is treated with caustic soda, and the ripening of the alkali cellulose is omitted.  Viscose solutions having a gamma number above 60 may have a cellulose content of 4-11 per cent by weight and caustic soda of 3-12 per cent by weight.  The stretching may be up to 400 per cent and may take place partially or wholly in the bath or partially or wholly in air, and may be performed between driven rolls rotating at different speeds or by friction by means of tubular rods.
