Patent GB-749029-A (GB)
Title: Improvements relating to blast refined low carbon steel
IPC: C22C38/00
Filed: 1953-11-05
Abstract: A blast refined steel has a carbon content below 0,015 per cent and a manganese content which is below 0,25 per cent and more than 1,7 times the percentage of sulphur.  Preferably, it has a residual oxygen content after deoxidation of not more than 0,05 per cent and such a content of phosphorus and nitrogen that the sum of the phosphorus content together with ten times the nitrogen content is within the range 0,15-0,30 per cent.  If the manganese content of the pig-iron is so low as to give on blowing a steel of lower manganese percentage than that desired, an alloy rich in manganese, e.g. silico-manganese, is added to the molten steel.  By way of example (a) a basic Bessemer pig-iron is blown to a steel containing 0,01 per cent C, 0,092 per cent P, 0,19 per cent Mn and 0,045 per cent O and (b) a basic Bessemer pig-iron is blown to a steel containing 0,009 per cent C, 0,085 per cent P, 0,17 per cent Mn, 0,024 per cent S and 0,058 per cent O.  This is deoxidised and its manganese content increased by adding silico-manganese containing 60 per cent Mn and 25 per cent Si when pouring into the ladle, thus giving a final steel containing 0,009 per cent C, 0,01 per cent Si, 0,20 per cent Mn, 0,090 per cent P, 0,024 per cent S and 0,035 per cent O. Specification 686,790 is referred to.

Abstract: 943,300. Measuring gas reversion pressure. NORTH WESTERN GAS BOARD. Aug. 15, 1962 [ Aug. 25, 1961], No. 30666/61. Headings G1B and G1S. The flame reversion pressure of a gas (i.e. the pressure at which a flame 4 which has been lifted from a burner 3 reverts to the burner) is measured by varying the gas supply pressure, e.g. by a governor 5 operated by a driven cam 6 acting on a lever 7 or alternatively by closing a number of valves in parallel in the supply line. The reversion of the flame to the burner is detected by a heat conducting probe 21 which causes expansion of gas in a bulb 15 causing a column of mercury to complete a circuit through battery 18 to a relay 17. This opens valve 14 and permits the pressure supplied to burner 3 to be communicated to a pressure recorder 21. The reversion of the flame may alternatively be detected by a heat or light sensitive cell, thermo couple expansion or resistance thermometer, acoustic sensitive cell or microphone, or flame conductivity detector.

Title: Process for manufacturing soap
IPC: C11D13/04
Filed: 1946-10-21
Abstract: <PICT:0636945/III/1> Soap is produced substantially free from glycerol and rancidizing factors, without the usual salting out and fitting steps, by continuously washing neat soap with a brine solution of a concentration close to the critical concentration below which the neat soap would dissolve in it.  Neat soap is that soap phase between the middle and curd soap phases wherein the soap concentration is such that the soap is still liquid and is in the form of a water-in-soap dispersion.  The concentration of the brine solution is preferably a little above the critical concentration and the treatment is preferably effected at a temperature of about 100 DEG  C.  The excess salt is then removed from the soap by washing with an alkaline lye, such as sodium hydrate lye, also having a concentration close to and preferably in excess of the critical concentration.  The alkali remaining in the soap may be neutralized by addition of a fast-acting saponifiable fat, such as coconut or palm kernel oil, fatty acid or other product capable of neutralizing the free alkali while allowing the final soap product of suitable grade to be obtained.  The soap without further drying is then ready for milling, moulding, &c. The alkaline lye-salt liquor may be treated to recover the lye for use in the saponification stage.  A suitable plant comprises three brine washing stages E1, E2, and E3, and a final alkaline lye washing stage E0, each stage being equipped with a washing liquor supply tank r, a mixer m and a separator s. The soap path is indicated by full arrows, the glycerol being removed therefrom at B; the brine path is shown by broken line arrows commencing at C, the glycerol loaded brine being discharged at D, and the alkaline lye path is illustrated by dotted line arrows commencing at F, the alkaline lye being discharged at G.  Fatty acid from a tank I is used to neutralize the alkaline soap from H for discharge as neutral soap at J.  Specification 320,331, [Class 91], is referred to.
