  • Permanent-wave solution
    Patent number: 4322401
    Abstract: Permanent-wave solution comprising an aqueous alkaline solution of cysteine and an organic acid anhydride as added thereto in a molar ratio of 0.1 to 0.5 per each mole of cysteine is disclosed. The solution is stable upon exposure to air while retaining a sufficient curling effect on the hair.
    Type: Grant
    Filed: December 18, 1980
    Date of Patent: March 30, 1982
    Inventor: Morio Harada
  • Permanent waving composition
    Patent number: 4139610
    Abstract: Permanent waving composition containing as active ingredients cysteine and N-acetylcysteine. The composition contains preferably 3-15% cysteine and 0.2-3% N-acetylcysteine. It is possible to avoid the separation of crystals derived from the air-oxidation of cysteine by the composition of the present invention.

  • Method of refining carbon-unsaturated system ferro-chromium
    Patent number: 3953195
    Abstract: Refining with the requirements that a mixing rate of powder ore to lump ore is prepared in the range of 20 to 50%, the amount of SiO.sub.2 in the charging raw materials is readjusted to which the amount of SiO.sub.2 in the slag is in the range of 35 to 45% and impedance of volt-ampere between the electrode and the bottom of furnace is more than 1.6 .times. 10.sup..sup.-3.OMEGA. carbon-unsaturated system ferro-chromium of which both S and Si are low can be easily and stably obtained without desulfurizing out of the furnace.
