  • Method of and apparatus for measuring layer thicknesses and layer homogeneities in containers
    Publication number: 20070229844
    Abstract: The invention concerns a method of measuring layer thicknesses and layer homogeneities in transparent, internally lubricant- and water-repulsion-coated containers, wherein a lens (2) focuses polychromatic light on to the internal coating (1B) of the container (1), the reflected light is detected again, coupled into a spectrometer and registered by way of a sensitive multichannel detector (7), and corresponding signals are transferred to an electronic evaluation means (8) which digitises the signals and computes the layer thickness from the interference pattern.

  • Microcapsules comprising functionalised polyalkylcyanoacrylates
    Publication number: 20030157023
    Abstract: The invention relates to gas-filled microcapsules that consist of functionalized polyalkylcyanoacrylates that are produced by copolymerization of one or more alkylcyanoacrylates with a functional monomer and/or by partial side-chain hydrolysis of a polyalkylcyanoacrylate, as well as a process for the production of gas-filled microcapsules and their use for ultrasound diagnosis.

  • Multi-stage process for the production of gas-filled microcapsules with defined narrow size distribution by defined external gassing during the build-up of microcapsules
    Publication number: 20020172762
    Abstract: The subject of the invention is a multi-stage process for the production of narrowly-distributed gas-filled microcapsules. In one process step, polymerization of the shell-shaping substance(s) takes place, and in a process step that is separated from it in space and/or time, the formation of the microcapsules by a build-up process takes place. The build-up process is carried out by low-energy defined gas input of the gas that is to be encapsulated with the aid of a porous membrane that has small defined pore openings.
