Patent EP-0371265-A1 (EP)
Inventor: BERTHOLD FRITZ DR
IPC: G01N33/553
Filed: 1989-10-27
Abstract: In a method for measuring chemiluminescence by means of a photomultiplier (70), for example in immunoassays, the sample vessel (10), which is to be led past the measurement opening (71) of the photomultiplier, is subjected to the action of an essentially temporally constant magnetic field (40), the resultant force of which draws away from the entry window (measurement opening) of the photomultiplier the magnetic microparticles (20) which are located in the solution in order to increase the reactive surface, so that during measurement said microparticles are held outside the optical path of the chemiluminescence photons, and thus cannot attenuate the intensity of the signal to be measured. By contrast with previously known methods, in which the microparticles are separated from the sample to be measured, this solution enables the microparticles to remain in the solution even during the actual measurement process, thus saving, in particular with immunoassays, a few steps in the method and the problems connected therewith. <IMAGE>

Abstract: The invention relates to performing exchanges between two fluids by means of a stack of membranes (13, 13') between which separator frames (1, 1') are interposed. According to the invention, the seal plane is obtained by assembling four thermoplastic sheets about a screen (8), with the outermost two sheets (16, 17) being flexible and hollowed-out in zones corresponding to diffusers, and with the inner two sheets (14, 15) situated on either side of the screen (8) being semi-stiff, with at least one of them not including an opening in the diffuser zone. The four sheets are assembled together without exerting pressure over the diffusers (9) such that the, or each, semi-stiff sheet forms a protective element over a diffuser zone.

Abstract: Fuel injection pump for supercharged internal combustion engines whose delivery adjustment element (10) has a travel limitation in the form of a stop lever (38) adjustable as a function of the charge air pressure. The deflection of a diaphragm (42) as a function of the charge air pressure is translated into a rotation of the intermediate element (54) by means of a lifting rod (52) acting on a lever (56) of a pivotally mounted intermediate element (54). The stop lever (38) is pivotally mounted in a carrier lever (58) pivotally mounted in one section (41) of the housing. A bolt (67) projects from the intermediate element (54) eccentrically to its axis (55) towards the stop lever (38), the stop lever (38) coming to bear on this bolt. As the charge air pressure increases the intermediate element (54) rotates with the bolt (67) which releases the stop lever (38) in the direction of an increased fuel injection quantity. A return spring (70), the pretensioning of which is variable, engages on the intermediate element (54). The carrier lever (58) is supported on an adjusting screw (83) by means of which basic setting of the fuel injection quantity at full load is possible in that the carrier lever (58) including the stop lever (38) is rotated in the housing section (41). <IMAGE>

Abstract: Un convolutionneur à ondes de surfaces (C) consiste en un cristal piézoélectrique allongé dont les extrémités portent des convertisseurs interdigitaux destinés à la conversion de signaux d'entrée électriques, présents aux entrées de signal (E1, E2), en signaux de surface acoustiques. Sur son électrode d'intégration, un signal de sortie (c(t)) correspondant au produit de convolution des signaux d'entrée électriques est prélevable. Afin de compenser les défauts provoqués par la non-uniformité du convolutionneur (C) à ondes de surface par suite du manque d'homogénéité de son électrode d'intégration et du cristal piézoélectrique, à l'une des entrées de signal (E1) est injecté un signal d'entrée constant (u(t)), et à l'autre entrée de signal (E2) du convolutionneur (C) à ondes de surface est injecté un signal prédéterminable (v(t)) définissant une réponse d'impulsion désirée du convolutionneur (C) à ondes de surface. Les signaux de sortie (c(t)) sont libérés par calcul de la valeur moyenne pour la formation de la grandeur de compensation (K(t)) de fractions pertubatrices stochastiques. La grandeur de compensation est amenée, synchronisée avec le signal prédéterminable (v(t)), au signal de sortie (c(t)) du convolutionneur (C) à ondes de surface lorsque des signaux d'entrée (u(t)) à traiter sont présents à l'entrée du signal (E1).
