Abstract:
A portable device for the quality control of vegetal products comprising a power supply (7) intended for powering a circular crown of lighting lamps (41) at the centre of which there is arranged the receiving objective of a spectrometer (45) provided with means (431) adapted for resting on the product to be checked, said spectrometer (45) being associated to a microprocessor (11) which provides the measurement data on display means (12); according to the invention, the lamps (41) are permanently powered, and in stand-by, at a reduced voltage (70), lower than the nominal voltage (71) delivered by the power supply (7), and instantaneously at the nominal voltage (71 supplied by the power supply (7) through a power circuit (8) whose activation is commanded and controlled by the microprocessor (11) in response to an activation signal generated by a button (10).
Abstract:
A method of protecting a sensor (300) for use in an environment in¬ cludes: providing a protective enclosure formed in a plurality of sec¬ tions (110a, 110b), at least a first section (110a) of the plurality of sections being movable relative to a second section (110b) of the plurality of sections so that the protective enclosure can be placed around at least a portion of the sensor (300); placing the first section (110a) adjacent the sensor (300) while the first section (110a) and the second section (110b) are in an open state; and moving the second section (110b) to place the first section (110a) and the second sec¬ tion (110b) in a closed state in which the first section (110a) and the second section (110b) encompass the at least a portion of the sensor (300).
Abstract:
Refraktometer mit einem Gehäuse (1), einer im Gehäuse (1) angeordneten Messzelle (8) und einer Deckeleinheit (2), welche eine Grundplatte (3) mit einer Aussparung (7), die einen Zugang zur Messzelle des Refraktometers bildet, und eine Deckel (4) zum Abdecken der Messzelle aufweist, wobei der Deckel (4) über ein Scharnier mit der Grundplatte (3) verbunden ist, dadurch gekennzeichnet, dass die Deckeleinheit (2) ferner einen Deckeleinsatz (11, 17, 18, 28, 31, 35, 39) aufweist, welcher Deckeleinsatz (11, 17, 18, 28, 31, 35, 39) auswechselbar im Deckel (4) angeordnet ist, und dass die Deckeleinheit (2) über ein mit der Grundplatte (3) verbundenes Verbindungselement lösbaren mit dem Gehäuse (1) verbunden ist.
Abstract:
Apparatus for analysing a liquid sample (194) comprises beam generating means (1) for generating electromagnetic radiation, detector means (8) for detecting electromagnetic radiation from the beam generating means after the radiation has interacted with the sample, and sample retaining means (10) for releasably retaining sample in the path of the beam. The sample retaining means comprises a hydrophobic surface (for example, a coating on a plate 118) on which the sample is, in use, supported. There is also disclosed a method of performing photometric or spectrophotometric analysis of a liquid sample by sandwiching samples between two opposed hydrophobic support surfaces, passing a beam of electromagnetic radiation through one of the surfaces and then through the sample, and analysing the beam after it has passed through the sample.
Abstract:
The invention relates to a fluorometer having a partly transparent mirror (27) through which excitation light is directed to the sample and via which emitted light from the sample is reflected. Thus a high sensitivity and, furthermore, as homogenous a measurement sensitivity distribution as possible within the vessel are achieved. Measuring can be carried out from either above or below. The invention is applicable for use especially when the fluorometer has simultaneously a plurality of samples.
Abstract:
Die Erfindung betrifft eine Vorrichtung für die Messung physiologischer Parameter von in einem extrakoporalen Kreislauf gefördertem Blut. Zwei Lichtquellen (1a, 1b) strahlen Licht unterschiedlicher Wellenlänge in einen kugelförmigen Hohlraum (3) mit einer reflektierenden inneren Oberfläche (3a) ab. Eine Lichtsensoreinrichtung (2) empfängt einen Teil des sich in dem Hohlraum (3) ausbreitenden Lichtes. In einen zweiten Hohlraum (4) ist ein Schlauchabschnitt des extrakorporalen Kreislaufs so einlegbar ist, daß das von den Lichtquellen abgestrahlte Licht (La, Lb) auf die Grenzfläche zwischen dem Blut und einer Innenwand des Schlauches auftrifft. Durch Reflektion und/oder Transmission gelangt das Licht zumindest teilweise in den Hohlraum (3) zurück.
