Patent EP-0427847-A1 (EP)
Inventor: GATZ CARSTEN
IPC: B41M3/14
Filed: 1990-06-08
Abstract: Un papier de sécurité permet de produire des documents qui peuvent être identifiés comme authentiques au moyen d'un système de réaction chromogène formé d'un agent chromogène et d'un révélateur chromogène, selon le principe du papier de tirage sensible à la pression, l'agent chromogène étant appliqué sur le papier pourvu du révélateur chromogène au moyen d'un appareil de marquage. Il existe déjà des systèmes de sécurité pour documents qui fonctionnent selon le principe des papiers de tirage sensibles à la pression. Ces systèmes présentent toutefois des inconvénients que l'invention essaie d'éliminer. A cet effet, le révélateur chromogène est uniformément distribué dans le papier. Lorsque le papier de sécurité est mis en contact avec un fluide de marquage qui contient un agent chromogène, la réaction entre le révélateur chromogène présent dans le papier et l'agent chromogène ne se produit plus, comme jusqu'à maintenant, à la surface du papier, mais dans le papier lui-même. Le marquage pénètre ainsi dans le papier et peut même le traverser jusqu'à l'autre face, où il est reproduit à l'envers. Il devient donc impossible d'enlever un tel marquage du document sans détruire le document lui-même. Un autre grand avantage est le fait que ce papier à révélateur chromogène intégré représente ainsi un véritable papier de sécurité, comparable à d'autres papiers spéciaux usuels (pourvus par exemple d'insertions fluorescentes, de planchettes, de filigranes, de fils métalliques et similaires) non accessibles à tout un chacun, ce qui augmente considérablement la sécurité obtenue.

Abstract: A method of producing cemented carbide or cermet alloy comprising mixing and kneading cemented carbide powder or cermet alloy powder with an organic binder, molding this mixed powder into a predetermined shape by injection molding, removing the organic binder from the resulting mold and sintering the mold to obtain a compact alloy. The removal of the organic binder is carried out in a first removing step in an inert gas atmosphere and subsequently in a second removing step in vacuum of 1 Torr or below. In the first removing step, the pressure of the atmosphere is kept at or above the atmospheric pressure so as to prevent the occurrence of defects in the mold. After continuous fine pores are formed inside the mold, the pressure of the atmosphere is kept near vacuum in order to promote the evaporation of the gas from the surface and the release of the gas generated inside the mold.

Title: Procede de codage d'images bicolores au moyen de deux motifs
Inventor: KUETTNER HEINRICH
IPC: A63F3/06
Filed: 1990-10-01
Abstract: Un procédé de codage d'images part d'une image initiale en deux couleurs, par exemple en noir et blanc. Le procédé vise à décomposer une image en noir et blanc en deux motifs. Ni l'un ni l'autre motif ne permettent de reconnaître l'image initiale, mais lorsqu'ils sont superposés, l'image devient visible. Des points noirs sont affichés par exemple en tant que surfaces noires et des points blancs en tant qu'un motif en noir et blanc qui paraît gris. A cet effet, chaque point de l'image est représenté dans un des motifs par une partie du motif qui colore 50 % de la surface correspondante. L'autre motif est coloré si à l'endroit correspondant un point d'image d'une ou de l'autre couleur doit être représenté. Par exemple, pour des points noirs, l'autre partie de la surface est noircie. La figure 2 montre le résultat obtenu avec ce procédé. L'image de l'avion est obtenue par superposition d'un motif initial et d'un motif superposé. Le texte ''IHRE ZEITUNG'' est fixe et sert de point de repère.

Abstract: Transmission series with a variable gear stage (variation stage) consisting of a pair of gearwheels. Within the series, the variation stage encompasses a range of permissible sizes (B i  = B₁... B m ) which in each case have the same centre distances (A i  = A₁ ... A m ). The same range of permissible transmission ratios (I i  = I₁... I n ) is provided for all sizes, so that the centre distances (A i ) and the transmission ratios (I i ) form a matrix (M). The number of components required is substantially reduced by correlating the graduation of the centre distances (A i ) and the graduation of the transmission ratios (I i ) in such a way that the same gearwheel is used in a variation stage sequence (S) comprising a number of variation stage sizes.

Abstract: The invention relates to a process and apparatus for separating off copper, in particular from CuCl2 etching solutions. Advantageously, a major part of the copper is recovered by loading a cation exchanger with concentrated CuCl2 etching solution and thus exchanging the H<+> ions for Cu<2+> ions, washing the cation exchanger after breakthrough and then loading it with H2SO4 for regeneration, the Cu<2+> ions being replaced again by H<+> ions, washing the cation exchanger after breakthrough, and passing the CuSO4 solution arising in the regeneration into an electrolysis bath and electrolytically precipitating the copper. This process is advantageously carried out in an apparatus which comprises a cation exchanger downstream of the CuCl2 etching agent stream of the etching apparatus, the inlet of the exchanger being connected to a feed tank (16) containing concentrated CuCl2 etching solution and to a tank (26) containing H2SO4, and the outlet (36) thereof being connected to a replenisher tank (17) containing weakly concentrated CuCl2 solution and to a feed tank (44) which contains CuSO4 solution and to which an electrolysis bath (47) is connected. <IMAGE>

Abstract: A novel gasifying combustion method is proposed. Fuel, desulfurizing agent and air are fed into a fluidized bed gasification furnace and a part of the fuel is gasified. Then produced combustible gas is led into a combustor. Residual fuel not gasified within the fluidized bed gasification furnace is led to a fluidized bed combustion furnace jointly with the desulfurizing agent to burn it with air fed separately. Then produced combustion gas is led into the combustor, in which the combustible gas is burnt with the combustion gas and air fed separately. A method for controlling the amount of air fed to the respective furnaces and the combustor is disclosed. A novel gasifying power generation method includes, in addition to the above-mentioned steps of the gasifying combustion method, the steps of driving a gas turbine by the combustion gas produced by the combustor, driving a steam turbine by steam generated by the combustion gas, and rotating electric generators by the respective turbines to carry out power generation.

Abstract: A headup display apparatus consists of a projection optical system unit (19) installed in the dashboard of a car and a reflection member on the windshield. The projection optical system unit (19) contains an indicator (1) and an off-axis reflective hologram (2) which reflects display light (f) of the indicator (1) toward the windshield, which in turn reflects it toward the viewing point of a driver. As a result, the display is seen superimposed on the exterior view. When external light (i) as from the sun enters the projection optical system unit (19) traveling in a direction reverse to the path of the display light (f), the off-axis reflective hologram (2) reflects the incident external light (i) toward a direction different from that of the outgoing display light to minimize an abnormal illumination of the indicator surface which would otherwise render the display unrecognizable. Behind the hologram (2) is installed a heat dissipating member that receives infrared rays that have transmitted the hologram in order to dissipate heat.
