  • Patent number: 8598338
    Abstract: The present disclosure provides methods for isolating substantially pure and undegraded DNA from biological material via a solid support. The methods may use a DNA lysing solution that comprises a surfactant, a DNA-complexing salt (e.g., a lithium salt), and a buffer. Alternatively, the methods may use a solid support pre-treated with the DNA lysing solution.

  • Patent number: 7329430
    Abstract: The present invention relates to a method for coating of a pharmaceutical product. The method comprises the step of producing discrete droplets (7) of controlled size, shape and composition with at least one micro dispenser (1) and distributing droplets (7) with controlled velocity, time of flight. Also, the method comprises the step of controlling the production frequency and modulation of the droplets (7). Further, the method comprises the step of controlling the flow rate, temperature and composition of the carrier gas and directing droplets (7) towards particles (10) subjected to coating. The present invention also relates to a device for coating of a pharmaceutical product. The device comprises a droplet producing unit (1) and a droplet-directing unit (8). The droplet producing unit (1) is a piezo-actuated micro dispenser (1) for producing discrete droplets (7) and controlling the size, shape and composition of said droplets (7).

  • Patent number: 6946157
    Abstract: In a method of monitoring the formation of a coating on a single particle (P), an apparatus is used which comprises means (2,5,6,9) for arranging said particle (P) at a given spatial location, and a fluid supply unit (3) adapted to apply a coating fluid to the particle (P) such that the coating is formed. Further, the apparatus has a measurement unit (4) which is adapted to perform a spectrometric measurement on the coating during formation thereof, and to derive a measurement value of at least one principle parameter related to the coating. This, such principle parameters, for example the thickness, thickness growth rate and physical and/or chemical properties related to the quality of the coating, as well as heat, mass and momentum transfer, can be continuously and non-invasively monitored during the coating process on the single particle (P).

  • Patent number: 6212672
    Abstract: A software development tool utilizes an intermediate object modeling language. The structure of the desired program is first described graphically by generating rule diagrams, state diagrams, and object diagrams such as user interface diagrams, event diagrams and other object diagrams. The development tool employs the diagrams to generate a working model of the program expressed in the object modeling language. The working model of the program can be executed without lengthy compiling, and hence program behavior can be quickly observed and tested. Further, the behavior of the working model can be quickly and easily changed by modifying the diagrams until the desired result is achieved. Source code is then generated from the object modeling language and compiled to create the final program.
