Patent number: 6556295Abstract: A method and device for optical measuring of small particles for analysis of the quality of the particles. A sample-feeding carrier is adapted to take up particle samples in sample holders and transport the particle samples to a place for optical measurement. A mirror-supporting means follows the movement of the carrier and has mirrors matching the sample holders. A device illuminates a particle sample when positioned for optical measurement and a detector, which is sensitive to electromagnetic radiation, records a result of optical measurement of the illuminated particle sample. A mirror reflects the particle sample, so that a mirror image thereof stands essentially still seen from the detector, when a measurement is being recorded, owing to the fact that the mirror image of the particle sample falls on a center axis of the movement of the mirror-supporting means.Type: GrantFiled: January 29, 2001Date of Patent: April 29, 2003Assignee: Foss Tecator ABInventors: Erland Leide, Nils Wihlborg, Håkan Wedelsb{haeck over (a)}ck, Tomas Jonasson, Roger Ylikangas

Publication number: 20030063276Abstract: A method for segregating qualities of an agricultural product during processing of the product comprises the step of setting a desired range of a measurement value (2). The measurement value represents a property of the product and defines a first quality of the product for which the measurement value is inside the range and a second quality of the product for which the measurement value is outside the range. The method further comprises the step of analyzing (4) the quality of the product that is being processed. The step of analyzing comprises the steps of continuously extracting samples of the product (4a), irradiating each sample by electromagnetic radiation (4d), spatially separating electromagnetic radiation of different wavelengths (4e), and detecting electromagnetic radiation emitted from the sample (4f). The step of detecting produces intensity signals indicative of detected electromagnetic radiation of different wavelengths.Type: ApplicationFiled: April 10, 2002Publication date: April 3, 2003Applicant: FOSS TECATOR ABInventor: Robert Sjodin

Patent number: 5961787Abstract: A solvent extraction apparatus which includes a heating plate, a vessel for containing a solvent, an extraction thimble to obtain a sample to be extracted from said vessel and a cooler for condensing evaporated solvent vapors. The cooler is connected to the vessel for containing the solvent, preferably by an adaptor. A lifting rod is provided which passes through the cooler which, at its lower portion, is provided with a drip rim on which the extraction thimble is detachably fixed. The thimble can be moved vertically by the lifting rod and the flow of solvent into and out of the cooler can be regulated by the lifting rod.Type: GrantFiled: December 16, 1997Date of Patent: October 5, 1999Assignee: Foss Tecator ABInventors: Goran Persson, Finn Alstin

Patent number: 5695719Abstract: A fully functional analyzing unit is included within the fluid-tight housing of a dialyzer which may be immersed in the medium to be analyzed. An opening in the housing is closed by a dialysis membrane. A channel defining body cooperates with the membrane to define a flow channel. The unit includes a carrier fluid reservoir and a carrier pump for generating a flow of carrier fluid through the flow channel. By dialysis via the membrane, the flow of carrier fluid is transformed into a flow of sample fluid which is received in a reaction channel. Reagent fluid from at least one reagent reservoir is delivered to the reaction channel by at least one reagent pump, and a detecting device is coupled to the reaction channel for detecting a reaction product originating from a reaction between the reagent fluid and the sample fluid and for generating a corresponding detection signal. Effluent from the reaction channel is received in a waste reservoir.Type: GrantFiled: October 30, 1995Date of Patent: December 9, 1997Assignees: Danfoss A/S, Tecator ABInventors: Anders Lynggaard, Ib Espensen, Theiss Stenstr.o slashed.m, Bo Karlberg, Ole Ploug, Steen Gaardsted Kristensen, Niels Eisum

Patent number: 4725817Abstract: An instrument adapted to make assessments in sensory evaluation comprises two wafers which are separated by spacers and are provided on their opposing faces with conductive patterns. Upon use, the instrument is connected to a computer which activates one conductor at a time on one side of the instrument and senses if one or more of the conductors on the other side of the instrument are activated, i.e. if a person is exerting a pressure, for example by a finger, at some point or other on the instrument. The special design of the conductive patterns makes it possible to convert the analog position of the pressure into a digital signal which is fed directly into the computer.Type: GrantFiled: July 26, 1985Date of Patent: February 16, 1988Assignee: Tecator ABInventor: Nils Wihlborg
