  • Patent number: 5476601
    Abstract: A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes a water-soluble organic material selected from amine oxides and quaternary ammonium salts, fluozirconate, fluohafnate, or fluotitanate ion, and preferably also phosphate and nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.

  • Patent number: 5455370
    Abstract: Fatty acid glycerides can be transesterified with lower aliphatic alcohols if the reaction is carried out in the presence of fatty acids corresponding to formula (II):R.sup.2 --COOH (II),in which R.sup.2 is an aliphatic hydrocarbon moiety containing 11 to 17 carbon atoms and 0, 1 or 2 double bonds. The products are distinguished by a low content of bound glycerol and a low acid value. Removal or neutralization of the catalyst is unnecessary because, after the transesterification, the fatty acids are also present in the form of their esters.

  • Patent number: 5454882
    Abstract: The invention is a method for the accurate control of the conversion film thickness produced on aluminiferous metal materials by fluorine-containing acidic conversion treatment baths; and a simple method for determining the EFC value (Effective Fluorine Concentration). The EFC value is determined by potentiometric titration of a fluorine-containing acidic conversion treatment bath having pH<4 without prior pH adjustment using a fluorine ion electrode as indicator electrode. The titrant is an aqueous solution containing the Al ion, La ion, Y ion, Zr ion, Ga ion, Ce ion, or Be ion, an inflection point in the potential curve is used as an indication of the activity of the conversion treatment bath.

  • Patent number: 5453200
    Abstract: In a process for separating the exocellular proteins from the micro-organisms of a filtered fermentation liquor, the removal of solid is to be improved while retaining the useful substance. This is achieved by, in a first stage, removing substances preventing protein precipitation with the aid of a solid adsorption agent; concentrating the remaining solution to a protein content of about 30 to 40% by weight; and then precipitating and separating the protein, optionally with the addition of precipitants for protein to accelerate the precipitation, at pH values between 6 and 10.
