  • Patent number: 6613927
    Abstract: The present invention provides a stable, sterile, pharmaceutical product that consists essentially of lyophilized ifosfamide and solutions thereof. The lyophilized ifosfamide of the present invention is suitable for pharmaceutical use, and can be stored in one or more aseptically sealed containers. The present invention further provides a method of producing lyophilized ifosfamide, which method includes freezing a sterile solution of ifosfamide and subjecting it to a primary drying stage. The primary drying stage includes applying a vacuum to remove solvent while raising the temperature to a primary drying temperature, to produce a first intermediate. The first intermediate is subjected to a secondary drying stage, which includes applying a vacuum to further remove solvent while raising the temperature to a secondary drying temperature, to produce the pharmaceutical product.

  • Publication number: 20010047250
    Abstract: A computer-implemented method of visualizing a decorating project includes rendering an image of a building space (e.g., a room) that includes a number of structural objects (such as doors, walls, and furniture). The structural objects may be portrayed in the rendered image with visual characteristics that are determined by decorative materials (such as paint, fabric, or wallpaper) associated with the objects. The decorative material associated with a particular structural object may be determined based on user input selecting an object's decorative material from a group of available decorative materials. The method may also include generating a listing of selected decorative materials (e.g., for use in a subsequent decorating session) and sending the listing to a purchasing system. A computer-implemented decorating system includes a server operatively coupled to a memory, a database, and to a network over which data can be exchanged with client computers.
