  • Patent number: 8628807
    Abstract: A new composition of matter is provided comprising negatively charged polysaccharides which can be derived from Aloe vera and a process to prepare that composition of matter by sub fractionation of an extract of Aloe vera, passing the formed subfraction over a positively charged column and eluting the same with a salt solution. Optionally the Aloe vera is pre purified over a Sephadex G-25 column. This composition of matter and also the extract comprising the same which is formed after pre purification or ultra filtration of an Aloe vera extract is useful as a food supplement or in dietary foods, for use in personal care and in cosmetics, especially to prevent an infection with the bacteria Helicobacter pylori, Pseudomonas aeruginosa, Streptococcus mutans or Streptococcus sanguis.

  • Patent number: 7397940
    Abstract: A method for placement of a object such as a substrate or a mask on a table, said method including: a first placement step in which the object is placed on a first position on the table; a measuring step in which a displacement between the first position of the object and the required position of the object is determined; a removing step in which the object is released and removed from the table; a moving step in which the object and the table are moved relatively to each other by substantially the said displacement, in a direction substantially parallel to the surface of the table; and a second placement step in which the object is placed at the required position on the table.

  • Patent number: 7397539
    Abstract: The invention relates to a transfer apparatus for transferring an object. The transfer apparatus comprises a gripper for either gripping the object at a first position and then releasing the object at a second position proximate to a receiving structure or releasing the object at a first position after gripping the object at a second position proximate to the receiver structure. The transfer apparatus also includes a measurement device arranged to measure the relative position of the gripper with respect to the receiving structure in at least one dimension. Further, a relative position error is determined with respect to a desired relative position based on the relative position measured. The relative position of the gripper and receiving structure are adjusted in order to minimize the relative position error in the second position.
