  • Patent number: 8913247
    Abstract: A device for interferometric vibration measurement, having a radiation source for generating an original beam, a first beam splitter for dividing it into measuring and reference beams, a detector and a focusing device. The measuring beam at least partly reflected by the object and the reference beam are superimposed on a detection area of the detector, and the focusing device in the beam path of the measuring beam between the image unit and object focuses it onto a measuring point. Here, a measuring beam having a wavelength greater than 1100 nm is generated and the device has an image unit for two-dimensional imaging of the object surrounding the measuring point. The measuring beam focus lies in the focal plane of the image unit and, by use of the focusing device, the focal point of the measuring beam and the focal plane of the imaging unit are displaceable simultaneously.

  • Publication number: 20110090508
    Abstract: A device for interferometric vibration measurement on an object (8), having a radiation source (1) for generating an original beam, a first beam splitter for dividing the original beam into a measuring beam and a reference beam (4, 5), a detector (10) and a focusing device (9). The device is implemented in such a way that the measuring beam at least partly reflected by the object and the reference beam are superimposed on a detection area of the detector, and the focusing device is arranged in the beam path of the measuring beam for focusing the measuring beam onto a measuring point (7) on the object. It is important that, by using the device, a measuring beam having a wavelength greater than 1100 nm can be generated and that the device additionally has an image unit (12) for two-dimensional imaging of at least a sub-region of the object surrounding the measuring point.

  • Patent number: 5788991
    Abstract: One object of the invention, therefore, is to provide encapsulated biologically active solid microparticle agglomerates, each agglomerate comprising eitherIi) at least two closely associated microparticles, each microparticle being coated partially or completely by at least one discrete layer of a polymer, andii) at least one outer discrete coating layer of the same polymer which envelops the coated microparticles to form an agglomerate of closely associated microparticles, orIIi) a cluster of at least two closely associated microparticles, each microparticle being coated partially or completely by at least one layer of a polymer, the microparticles adhering together through the polymer to form said cluster, andii) at least one outer discrete coating layer of the same polymer which envelops said cluster to form a discrete agglomerate, wherein in types I and II an inter-phase boundary is formed between each particle and the first coating layer, between individual coating layers and between the outer agglomerat

  • Patent number: 5576009
    Abstract: A process for the preparation of microcapsules, which comprises rapidly stirring an aqueous solution of a precondensate of urea and a dialdehyde in the molar ratio of urea to dialdehyde of 1:1 to 1:2.5, into an acidified aqueous dispersion of a water-immiscible pesticide or a readily volatile water-immiscible solvent.
