  • Optical solid-phase biosensor based on polyionic layers labelled with fluorescent dyes
    Patent number: 5711915
    Abstract: The present invention relates to an optical solid-phase biosensor for the detection of molecules which can be labelled with a fluorescent dye for the identification of substances in solution, for which there exists a biomolecule (receptor) which specifically recognises these and is chemically bonded to the uppermost layer of one or more layers of polyions on the surface of the sensor, by measurement of the Forster transfer between another dye molecule which is bonded in one of the uppermost layers of the sensor, and the said dye molecule.

  • Method for the identification of plastics
    Patent number: 5329127
    Abstract: A method of identifying different plastics, wherein each plastic is provided with a plurality of fluorescent dyes which differ in terms of their emission frequencies and/or in terms of the duration of their fluorescence, so that a fluorescence pattern, which is distinguished by the duration of the fluorescence and/or by the frequencies occurring, can unambiguously be assigned to each plastic.
    Type: Grant

  • Apparatus for treating textile webs
    Patent number: 3955385
    Abstract: Apparatus for applying a treatment medium to a continuously movable textile web and subsequently drying the web comprises a treatment housing wholly supported by and thermally insulated from a dryer housing so as to minimize greatly the space required for the successive treating and drying operations. The treating housing preferably contains means which are operable to enable the web selectively to be treated or not treated.

  • Cloth feeding device for tentering machines
    Patent number: 3936915
    Abstract: A driven feed roller is disposed above a pair of needle chains. Members for spreading the web edges are located immediately preceding the feed roller, and a pair of needling rollers for impaling the web edges on the needle chains are located immediately following the feed roller in the direction of web movement. A device for sensing the web edges is arranged to scan the web edges on the feed roller.
