  • Publication number: 20070079707
    Abstract: The invention relates to a device (1) for preparing a beverage suitable for human consumption and having a fine-bubble foam layer. The device is provided with a beverage unit (2) for delivering the beverage under pressure and at least one nozzle (4) which is in fluid communication with the beverage unit for supplying the beverage to the nozzle such that the nozzle can generate a jet (12) of beverage. The device further comprises a receiving unit (14) into which the jet is directed for obtaining the beverage with the fine-bubble foam layer. The receiving unit is provided with a chamber (16) with at least one drain opening (18) for delivering the beverage with the fine-bubble foam layer and a jet impact member (20) accommodated in the chamber and having a top (22) that lies free from an inner wall (24) of the chamber.

  • Patent number: 5750334
    Abstract: The invention relates to the direct detection of human papillomavirus MRNA and DNA. The recently developed polymerase chain reaction was modified in order to improve the sensitivity and specificity. By choosing appropriate oligonucleotide primers (amplimers) and reaction temperatures, individual HPV genes from among the total cell DNA can be identified and amplified to an extent such that non-isotopic detection is possible. In addition, use of reverse transcription permits selective amplification of spliced mRNA and thus permits indication of premalignant or malignant conditions and/or lesions.
