Abstract: An electric power measuring device wherein input analogue signals representative of instantaneous values of current and voltage are applied to a multiplier (23) and the resulting product signal is applied to a converter (35, 37, 41, 43, 45, 47) to provide a pulse output signal having a pulse rate representative of the product, and hence of the level of power consumption. The converter is of the kind including a capacitor (35) which is charged during successive periods of equal duration by the product signal and a much larger reference signal which reverses at the end of each capacitor charging period until the capacitor charge does not reverse in polarity during a charging period, so that reversal of charge on the capacitor is assured during the next charging period, whereafter the direction of the reference signal is again reversed at the end of each charging period. The reference signal is constituted by a bias signal component in the output of the multiplier to avoid errors in the converter output pulse rate due to spurious variations in the output of the multiplier.

Abstract: Apparatus for modifying part of an image represented digitally in the frequency domain comprises a first memory (29) for storing a representation of the image digitally in the frequency domain as at least one first block of data locations containing frequency coefficient data. A second memory (30) is provided for storing a representation of the image part in the frequency domain by second blocks of data locations containing frequency coefficient data, the first and second blocks representing, after conversion to the spacial domain, spatially shifted versions of the image part relative to a fixed spatial co-ordinate system. A suitably programmed computer (31) applies a predetermined shift function defined in the frequency domain to the or each first block of data stored in the first memory (29) to generate the or each second block, and stores the resultant second blocks of data in the second memory (30).

Abstract: Une unité rotative d'entraînement est utilisée pour un tendeur d'une ceinture de sécurité. La ceinture est introduite autour d'un tambour d'entraînement (1) pourvu d'une surface adhérente (2) qui est comprimée contre la ceinture (3) lorsque le système est actionné. Lorsque la longueur de la ceinture à insérer est égale à 180 mm et si l'on utilise comme tambour d'entraînement un cylindre de piston rotatif à un seul étage, le diamètre extérieur du tambour mesure environ 70 mm, et si l'on utilise un cylindre de piston rotatif à deux étages, un diamètre extérieur mesurant uniquement 40 mm suffit. Un autre entraînement du tambour d'entraînement comprend un câble entraîné par un cylindre linéaire pyrotechnique. Ce genre de tendeur de ceinture de sécurité n'interfère pas avec les rétracteurs, fonctionne indépendamment des rétracteurs, s'associe bien avec une pince de serrage de la ceinture qui fonctionne uniquement en cas d'accident, est très compact et économique, compte tenu de sa construction mécanique simple qui comprend peu de parties. Dans un mode de réalisation particulièrement économique, avec l'addition de peu de parties supplémentaires, le tendeur est utilisé, après être activé, pour bloquer la ceinture, de sorte que le même élément supporte également la charge en cas d'accident.

Abstract: Une nouvelle technique de connexion de deux ou plusieurs unités de pompage (114, 116) sous une hotte à écoulement laminaire est décrite. La technique comprend l'utilisation d'un nouveau collecteur qui est conçu de manière spécifique pour améliorer l'écoulement d'air laminaire à travers l'orifice de sortie du collecteur lorsqu'il est connecté à l'une des unités de pompage. Le collecteur comprend une enceinte cylindrique ayant un orifice de sortie s'étendant axialement et deux ou plusieurs ensembles d'orifices d'entrée s'étendant radialement et partant de l'enceinte cylindrique. Les orifices d'entrée de chaque ensemble sont situés à intervalles rapprochés les uns par rapport aux autres pour réduire au minimum la longueur de l'enceinte cylindrique. Un canal de fluides commun s'étend sensiblement sur toute la longueur de l'enceinte cylindrique pour relier chacun des orifices d'entrée à l'unique orifice de sortie.

Title: Compositions a base de lipopolysaccharides et de facteurs naturels dans la therapie antitumorale et procede de traitement
Inventor: HOFFMANN MICHAEL K
IPC: A61K38/20
Filed: 1987-05-07
Abstract: Des lipopolysaccharides bactériens (LPS) peuvent être utilisés pour induire la libération dans le sérum de facteurs permettant le rejet de tumeurs et augmentant l'efficacité des agents antitumoraux ajoutés. Cela permet d'utiliser le TNF, en combinaison avec le LPS ou d'autres facteurs induits par le LPS, à moindres doses non toxiques pour provoquer le rejet de la tumeur. Ces facteurs peuvent être combinés dans une thérapie antitumorale avec d'autres agents chimiothérapeutiques tels que l'indométhacine ou le cyclophosphamide ou des agents naturels tels que le facteur thrombocitaire (4) qui bloquent les réactions négatives supprimant le système immunitaire, stimulant ainsi la résistance du corps à la thérapie.

Abstract: Dans un coupe-circuit comprenant un certain nombre d'éléments de contact mobile (20) et un nombre correspondant d'éléments de contact fixes (25, 26), au moins l'un des éléments de contact comporte un groupe de rouleaux de contact (20) sollicité par un ressort, plusieurs rouleaux (21, 22, 23, 24) étant disposés de façon à entrer en contact avec les surfaces latérales planes de deux barres de contact (25, 26) disposées entre lesdits rouleaux, lesquels peuvent glisser ou rouler sur lesdites surfaces durant la fermeture et l'ouverture du coupe-circuit. Afin de limiter le trajet nécessaire des éléments de contact mobile entre l'ouverture et la fermeture, on propose de disposer le groupe de rouleaux de contact (20) et les barres de contact (25, 26) qui coopèrent avec eux de façon à former un engagement échelonné. Les dimensions physiques dudit coupe-circuit sont ainsi réduites par rapport aux coupe-circuits de l'art antérieur, même lorsqu'il s'agit de coupe-circuits comprenant plusieurs pôles et destinés à fonctionner avec des courants de haute intensité.

Abstract: An apparatus for the transfer of a dry chemical is formed having a sealed solvation hopper positioned between a liquid driven eductor and a fitting for connection to a storage con­tainer, e.g. a railcar. At the inlet end (1) of the solvation hopper (9) is a chemical inlet pipe (13) which connects the interior to the exterior of the hopper (9). Surrounding the chemical inlet pipe (13) are a plurality of nozzles (7) for the introduction of solvation liquid into the hopper (9). The nozzles (7) are disposed such that the solvation liquid washes the interior surface of the hopper (9) to prevent plugging by hydrates (solvates) which may be formed. At the outlet end (10) of the hopper (9), the hopper is con­nected to the suction opening of a liquid eductor. In use, the exterior end of the chemical inlet pipe (13) is connected to the dry chemical storage container. Liquid flowing through the liquid eductor (7) creates a suction and draws dry chemical out of the storage container and into the hopper (9). In the hopper (9), solvation liquid is supplied through the nozzles (7) to wet the dry chemical and to wash the surfaces of the hopper (9), pushing the wetted material toward the outlet (10) end of the hopper (9). At the outlet (10) end of the hopper (9), the wetted material is sucked out into the eductor where it is combined with the flow of eductor liquid. The material leaving the eductor is recovered and sent either to storage or directly for processing.
