Patent EP-0483235-A1 (EP)
Inventor: BOEHMER DENNIS A
IPC: F02M37/20
Filed: 1990-06-05
Abstract: Un orifice d'air et une soupape de libération de surpression combinés destinés à une pompe submersible, comprennent un seul logement tubulaire à insérer dans un orifice se trouvant dans la paroi terminale supérieure d'une chambre, du côté de la pression de sortie de la pompe. L'extrémité supérieure de ce logement comporte un trou d'aération, et à l'intérieur du logement se trouve un siège de soupape annulaire tourné vers le haut. Une tête de soupape se trouvant à l'intérieur du logement est proportionnée pour se déplacer dans le sens de la longueur de ce dernier, vers le siège de soupape et à l'opposé de celui-ci, mais elle est normalement sollicitée pour venir en contact d'étanchéité avec le siège par un ressort se trouvant à l'intérieur dudit logement. Dans cette tête de soupape se trouve un trou de purge et une bille de soupape est enfermée dans la partie inférieure dudit logement, au-dessous du siège de la soupape pour permettre un mouvement d'obstruction et de désobstruction de l'extrémité inférieure du trou de purge se trouvant dans la tête de la soupape, à mesure que la pression régnant dans la chambre s'élève et chute. Si cette pression dépasse la force du ressort maintenant la tête de la soupape fermée, la tête sera amenée à se séparer de son siège se trouvant dans le logement, ménageant ainsi un chemin d'écoulement pour du liquide autour de la périphérie de ladite tête, dans et à travers le trou d'aération se trouvant dans la paroi terminale supérieure dudit logement.

Abstract: Procédé de récupération de zinc, cuivre et plomb de minerais et matériaux oxydés et/ou sulfurés à partir de diverses matières premières au moyen d'une lixiviation avec une solution concentrée de chlorure d'ammoniac qui donne lieu à la formation des amines correspondantes, et séparation des métaux de la solution fertile obtenue au moyen d'agents organiques acides d'extraction (agents cationiques d'extraction et/ou chélateurs) qui sont neutralisés par l'amine en régénérant la solution d'origine de chlorure d'ammoniac. Le cuivre et le zinc qui, séparément, sont passés à la phase organique correspondante sont extraits à nouveau de cette dernière tout en tirant profit de l'acide sulfurique obtenu au cours de l'électrolyse de la solution correspondante. Le plomb est séparé par cristallisation et obtenu sous forme de chlorure.

Abstract: A communication line joint arrangement comprising two parts (1,2) between which relative rotation and the transmission of at least two channels using electromagnetic energy such as light is facilitated, each part comprising polarising beam splitter means (3,4) operatively associated with quarter wave plate means (5,6), wherein the polarising beam splitter means of the two parts are arranged to pass two orthogonally related polarised input channel signals to the quarter wave plate means associated therewith, so as to produce two corresponding circularly polarised channel signals of opposite directional sense which are transmitted between the quarter wave plate means, across an interface (13) between the parts, so as to produce two corresponding orthogonally polarised output channel signals from the polarising beam splitter means. 
     By arranging that the two channel signals are circularly polarised in opposite senses as they traverse the interface between the two relatively rotatable parts, mutual interference between channels and/or breakdown of communication in the presence of rotation between the parts is thereby obviated.

Abstract: The fastening element (1) for insulation panels (2) is fastened to a hard building component (A) by means of a setting implement. To prevent damage to segments (6) in the mouth region of the recess (4b), the recess (4b) has a widening (4d). The latter corresponds to twice the wall thickness of a segment (6) and has a depth corresponding to the length of a segment (6). Thus, on introducing the mouth (8a) of a setting implement (8), besides the recess (4b) the bent segments (6) also serve as a guide face. On applying a coat of plaster (9), plaster material gets behind the bent-up segments (6) so that a fastening acting in a manner so as to engage behind is ensured.

Abstract: The present invention is concerned with method for preparing process flavourings, comprising the steps of:
     (a) mildly oxidizing fat to such a degree that the anisidine value of the fat is increased by at least a factor 1.5,   (b) preparing a Maillard reaction mixture comprising:
   (1) a carbohydrate ingredient selected from the group consisting of reducing carbohydrate, precursors of such carbohydrates, heat-degradation products of such carbohydrates and mixtures thereof,   (2) a nitrogen compound with general formula NHRR', where R and R' represent hydrogen, aliphatic group or aromatic group and where R and R' may be the same or different, and   (3) the oxidized fat obtained in step (a), the weight ratio of carbohydrate to nitrogen compound exceeding 1:20, and       (c) maintaining the reaction mixture at a temperature of more than 50°C for at least 2 minutes. It was found the incorporation of mildly oxidized fat in a Maillard reaction mixture upon subsequent heat treatment generates a relatively strong and in addition to that a balanced process flavouring due to the fact that also non-typical Maillard-type process flavourings are formed.

Abstract: A method for the treatment of zinc-containing by-products and waste materials from the primary and second production of nonferrous metals, particularly zinc- and lead-containing slags from the production of lead. The by-products and the waste materials are supplied to a gastight closed electric smelting furnace in which the materials are melted and subjected to a selective metallothermic reduction in order to reduce and volatilise zinc and other volatile metals. Elemental sulphur and/or sulphur compounds are added to the smelting furnace in an amount sufficient to form a sulphide phase containing one or more of the elements Cu, Ni, Pb, As, Bi, Sb and Ag. An inert slag phase and the sulphide phase are tapped from the furnace, and zinc and other volatile metals are recovered from the off-gas from the furnace by condensation.

Abstract: The singularities constituting the characteristic points of the image are points of contour with sharp curvature such as corners or regions of small size, the image being formed by a two-dimensional frame of pixels each exhibiting a defined grey level. The device of the invention comprises: differentiating means (10) approximating, for each pixel to be analysed, the partial, second-order derivatives of the grey level function of the image (F(x,y)); characterising means (23, 30), determining on the basis of these derivatives an attribute ( lambda 2) representative of the characteristic sought and assigning this attribute to the pixel thus analysed; and localiser means, searching among the pixels of the image thus analysed for the points maximising the said attribute. Very advantageously, the differentiating means (10) comprise convolving means carrying out a convolution of the grey level function of the image (F(x,y)) with functions corresponding to the partial, second-order derivatives of a regularisation function, this regularisation function making it possible to attenuate the noise present in the image. Preferably, the attribute chosen is the second eigenvalue of the matrix of the second derivatives, and the regularisation function is a Gaussian function, especially a centred Gaussian function. <IMAGE>

Abstract: The invention relates to an integrated circuit, especially for microprocessor chip cards which have to have several different functionalities at various hierarchical levels. The circuit comprises a microprocessor (10), a read-only memory (12) managing security, an EEPROM (16) memory capable of containing not only data but also code executable by the microprocessor. According to the invention various programmes are placed in the EEPROM memory (areas Z1C, Z2C, Z3C). The read-only memory contains filtering instructions serving for fetching a filter address from a specified area Z1B, Z2B, Z3B of the EEPROM memory. According to the content of this area, the programme will or will not be directed towards the areas Z1C, Z2C, Z3C. It is thus sufficient to pass on a single EEPROM memory address in order to control accessibility to the various functionalities of the circuit.
