  • X-ray fluorescence apparatus
    Patent number: 7720192
    Abstract: An X-ray fluorescence (XRF) apparatus uses both an analyzer crystal (6) and a silicon drift detector (34). By using this combination problems of background and overlapping peaks can be mitigated.
    Type: Grant

    Date of Patent: May 18, 2010
    Assignee: PANalytical B.V.
    Inventors: Petra Hegeman, Christian Brons, Peter Brouwer
  • PROCESS FOR PREPARING A METAL HYDROXIDE
    Publication number: 20090214416
    Abstract: The invention provides a process for preparing a metal hydroxide comprising the steps of: (a) providing particles of a metal silicate; (b) mixing the particles with a mineral acid solution to obtain a slurry which comprises precipitated silica; (c) separating the precipitated silica from the slurry to obtain a remaining solution; (d) increasing the pH of the remaining solution to such an extent that a metal hydroxide is formed; (e) separating the metal hydroxide so obtained from the remaining solution; and (f) adding to the remaining solution obtained in step (e) an acid solution, thereby forming a salt containing solution, or (g) removing at least part of the base added in step (d) from the remaining solution obtained in step (e), thereby forming a salt containing solution.

  • Stable aerated frozen food product
    Patent number: 4434186
    Abstract: In a process for preparing an aerated frozen food product such as mellorine or a shake beverage wherein water, fat, protein, emulsifier and stabilizer are blended together to form a mix which is homogenized to form an oil-in-water emulsion and is subsequently whipped under freezing conditions, improved stability is achieved in the product by selecting a specific oil having high solid fat content at room temperature, homogenizing the mix of ingredients under conditions sufficient to form an emulsion having a relatively narrow distribution of small diameter fat globules, and aging the emulsion to crystallize the fat globules prior to whipping. Stable aerated frozen products provided in accordance with this invention can be stored and distributed at 0.degree. F. without loss of quality and have a variety of commercial uses.
