Title: Improvements relating to the treatment of metal melts
IPC: C21C7/00
Filed: 1953-04-27
Abstract: A metal melt is treated by addition of a coherent body prepared by sintering, to form a porous skeleton, a powder of one or more metals and/or intermetallic compounds or compounds between metals and metalloids such as carbides and silicides and filling the pores of the skeleton at least partially with a treating agent having a lower melting-point than the skeleton.  For the treatment of iron and steel and ferro-alloy melts the skeleton may be formed from iron, steel or alloys thereof or alloying metals intended for the production of iron or steel alloys and may have a porosity of 5-70 per cent, preferably 15-50 per cent.  The pores may be filled with an alloying agent or a refining agent such as alkali metals, alkaline earth metals, magnesium, zinc or lead or alloys thereof.  Such refining agents may have a boiling-point lower than the temperature of the melt and have a strong affinity for at least one impurity in the melt.  The body may be prepared by filling the skeleton with a gas having a strong affinity for the treating agent and dipping the filled skeleton in a melt of the agent.  Examples are given of bodies suitable for deslagging and degasifying steel, production of nodular graphite cast iron, desulphurizing and dephosphorizing pig iron, purifying nickel, nickel steels and corrosion-resistant steels.

Title: Improvements relating to yarn winding, doubling and like machines
IPC: B65H63/028
Filed: 1932-04-26
Abstract: 400,945. Stop - motions and guide-bowl arrangements for yarn - winding machines. HIGGINSON, J. and ARUNDEL, COULTHARD, & CO., Ltd., Sovereign Works, Stockport. April 26, 1932, No. 12008. [Class 120 (ii).] In a yarn winding, doubling, or like machine a guide bowl or roller is provided between each supply bobbin and the cheese or bobbin being wound, which is carried by a part inter-connected with and actuated by the stopmotion so that when an end breaks and before the cheese comes to rest it shortens the yarn path by an amount which compensates for the length of yarn taken up due to overrunning of the cheese and thereby minimizes the extent to which the broken end is drawn towards the cheese. The bobbin cradle a, Fig. 1, is pivotally carried at c by a stop lever d itself pivoted at'h to a fixed bracket i and supported in the winding position by an arm f associated with the detector g. The yarn passes from the detector g round bowls 4, 5, 6. A link 11 is connected to the cradle a and to a lever 12 pivoted on a bracket x, the lever 12 carrying an adjustable stop 13 adapted to engage beneath the arm 14, pivoted at 15, carrying the bowl 5. Normally the arm 14 rests on the bracket x. When the stop lever d drops, the link 11 raises the lever 12 and thereby the arm 14 and bowl 5, thus shortening the yarn path to allow for the yarn wound up before the bobbin b comes to rest,' lost-motion being provided between the members 12, 14 to ensure that the bowl 5 is not lifted until the bobbin b is clear of the winding drum e. An arm w pivoted at w<1> to the bracket x is connected to the lever d by a link v and is adapted to engage an adjustable stop y on a lever z pivoted at 2 on the bracket x. The lever z carries a yarn deflector 3 and a torsion spring acting thereon urges the deflector towards the dotted line position in which it engages a lug 10 on the bracket x. When the stop lever d drops, the link v lowers the arm wand the deflector 3 rises to the dotted position moving the yarn clear of the guide 7. When the lever d is raised to start winding the first movement takes up the gap between the arm wand the stop y without moving the deflector 3 so that the bobbin b is rotating when the deflector 3 moves down to allow the yarn to enter the guide 7. Alternatively the bowl 6 may be lowered to the dotted position, Fig. 3, this arrangement also drawing the yarn forward clear of the guide 7.

Filed: 1932-04-28
Abstract: 400,649. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., CHOICE, F. C., LINEHAM, R. A., Belgrave Road, Leicester. April 28, 1932, Nos. 12204 and 26087. [Class 112.] A thread-waxing device of large wax capacity has a partition dividing the pot into two unequal compartments, the smaller of which and its walls being heated by a pair of electric heating elements controlled by a thermostat, and having communication with the larger one. The pot 1 may be surrounded by an outer casing 76 of aluminium to avoid loss of heat by radiation. The intermediate space may be filled with felt &c. A partition 9 with a hole 15 divides the pot into the unequal compartments 11, 13. One of the heater elements 5 is situated directly below the partition 9 and the other below the compartment 11. These elements heat up the wax in the compartment 11 very quickly as the rear wall and partition 9 are also heated. Wax flows in from the compartment 13 to replace wax used from the compartment 11. The plate 25 carries thread guides 29, 33 for carrying the thread through the hot wax in 11. Excess of wax is removed by the stripper plate 37 and stripper block 41. The pot 1 is supported on a pair of vertical rods and is brought up to the cover 21 to immerse the plate 25 which is thus pressed on to the hot base of the pot to keep the thread guides hot. The cover 25 can be swung sidewise to replenish the supply of wax. A thermostat 74 keeps the temperature of the wax between certain limits.

Title: An improvements in the continuous-cyclic process for the removal of sulphur dioxide from gaseous mixtures containing it
IPC: C01B17/60
Filed: 1959-04-10
Abstract: In a continuous cyclic process for the removal of SO2 from gaseous mixtures containing it by the successive absorption and desorption of SO2 in an aqueous organic base solution the aqueous organic base flowing down an absorption tower is first contacted with the SO2-containing gases and subsequently with free O2-containing gas to oxidise at least part of the absorbed SO2 to absorbed SO3 thereby increasing the capacity of the organic base absorb more SO2 from the gases. In operation absorption towers, e.g. packed towers or towers fitted with bubble plates, are fed through the top with a monophasic mixture of water and organic base, e.g. xylidine, toluidine, dimethylamine, quinoline, heavy pyridic bases from coal tar, methylamine or ethanolamines particularly diethanolamine. SO2-containing gases, e.g. roasting gases, chimney gases, converter gases, are fed into the middle zone of the towers where the SO2 is absorbed in the aqueous organic base.  Residual gases rise up the towers and exit from the top thereof.  Sufficient air or other gases containing free O2 is injected through the bottom of the towers to oxidise absorbed SO2 to absorbed SO3 to any desired degree, the oxidised base thereafter absorbing further quantities of SO2 from the SO2-containing gases.  Aqueous organic base leaves the bottom of the tower containing absorbed SO2 and SO3 in any desired ratio. Preferably the upper zone of the towers is cooled to avoid loss of organic base with the waste gases leaving the tower and the lower zone is heated, if necessary, (the process being exothermic) to 30-150 DEG C. and preferably to between 70 and 90 DEG C. above the temperature operating in the upper zone.  The lower zone may also be pressurised to 1-10 atmospheres, preferably 2-5 atmospheres absolute. The pressure and temperature of the lower zone are varied inversly to one another to obtain the desired absorbed SO2/SO3 ratio in the aqeuous phase.  Spent aqueous base leaving the absorption towers is subjected to heat and reduced pressure to free the SO2, which may be subsequently treated with water, ammonia or both to yield dilute sulphuric acid or ammonium or potassium sulphate.  The residual base liquor may be freed from absorbed SO3 by any desired method, e.g. treatment with a calcium compound to precipitate calcium sulphate, the pure regenerated base liquor being recycled to the absorption towers.
