  • Patent number: 4657857
    Abstract: The invention relates to yeasts of the genus Kluyveromyces, in particular K. lactis, acting as hosts for the expression of preprothaumatin or its various allelic and modified forms or their maturation forms, which yeasts contain an rDNA plasmid comprising a structural gene encoding for a thaumatin-like protein, an autonomous replicating sequence derived from K. lactis (KARS), a yeast regulon derived from the GAPDH-genes of S. cerevisiae, and a selection marker, e.g. the trp-1 or the lac-4 gene from S. cerevisiae and K. lactis, respectively. Optionally the plasmid also contains a transcription terminator from a yeast. Further the preparation of such yeasts and the preparation of thaumatin-like proteins with such yeasts and the proteins so obtained are claimed. The yeast described give a better expression than obtained with E. coli as described in EP-PA (A2) 0 054 330 and 0 054 331, published on June 23, 1982.

  • Patent number: 4647332
    Abstract: A thin foil or film is laminated to a substrate with an adhesive layer therebetween thicker than the surface roughness of the substrate, the laminating and drying of the adhesive being effected with the foil contacting a smooth contact surface under a contact pressure, the rate of heat input to dry the adhesive and the pressure on the back of the substrate being controlled to maintain the vapor pressure at the interface between the film and the adhesive above atmospheric and below the contact pressure so that the foil surface of the finished laminate is as smooth as the contact surface.

  • Patent number: 4637985
    Abstract: A process of carrying out a specific binding assay, for the qualitative detection or quantitative or semi-quantitative determination of an analyte which forms a component of a specific binding reaction, using a labelled conjugate form of a derivative or analogue of one of the relevant specific binding partners, said labelled form being capable of emitting delayed luminescence upon photo-excitation, characterized in that the labelled conjugate form of one of the relevant specific binding partners comprises a derivative or analogue of the specific binding partner with a derivative of a luminescent substance which shows a delayed light emission upon photoexcitation, the delayed light emission of which is subject to quenching by molecular oxygen, and characterized further in that the assay is carried out by the use of a time-resolved photometric method in the presence of an effective amount of a quench-inhibiting substance able to prevent quenching by molecular oxygen.

  • Patent number: 4625372
    Abstract: An apparatus is disclosed for the fabrication of a biaxially stretched flat film of thermoplastic material, particularly of polypropylene, with improved properties for a process in which the material is first partially pre-stretched in a longitudinal direction and, thereafter, simultaneously biaxially (longitudinally and laterally) stretched, the apparatus comprising stretching rollers for effecting partial longitudinal stretching of the film, the rollers being arranged upstream of an assembly for effecting simultaneous biaxial stretching of the film. The speed of the stretching rollers is infinitely variable so as to influence the total degree of film-stretching only by changing the speed of the rollers. The rollers used for longitudinal pre-stretching are arranged at the inlet section of the biaxial stretching assembly.

  • Patent number: 4597908
    Abstract: The invention provides a process for the preparation of a transition metal-silicate catalyst in which an insoluble, basic compound of a transition metal having an atomic number between 26 and 30 (in particular nickel which has an atomic number of 28) is rapidly precipitated with an alkaline precipitation agent from an aqueous solution of such a metal salt, as a suspension, which precipitate is allowed to mature for a longer period in a suspended form, and, after the transition metal ions have been practically completely precipitated, soluble silicate is added to the suspension, after which the solids are separated from the liquid, optionally washed, dried and reduced.

  • Patent number: 4584141
    Abstract: The present process for removing impurities from a triglyceride oil includes admixing a hydrolyzed phosphatide and water with the oil, separating the oil into an oil portion and a sludge portion and separating the sludge portion into an aqueous phase and an oil phase. The presence of the hydrolyzed phosphatides can aid the two separation steps. Recovery of oil from the sludge is thus possible.
