IPC: B01D53/77
Filed: 1990-10-05
Abstract: A method for purifying flue-gases and other hot, oxidative waste gases originating from industrial installations, combustion furnaces, engines and the like, whereby the hot gas to be purified is passed through at least one spraying chamber or -area and is contacted therein with a gas washing liquid, which is sprayed into the hot gas flow and cools the gas to below 100°C, whereby residual liquids with a high chemical oxygen consumption value, which comprise complex builders, compounds of heavy metals, sulphur- and nitrogen compounds, and originating amongst others from fixing-baths and the like from the photographic, photochemical and galvanic industries, are used as gas washing liquid.

Abstract: A process for manufacturing impellers of turbine pumps provides for subjecting disks (2) corresponding to the impeller to be obtained to electrical discharge machining, using tools (1) in form of plates (4, 10) provided with radial slits (5, 5′) extending along at least an arc of circumference and opening into hollow areas (7, 12). A combined motion of rotation and translation is imparted to the disks (2), thus generating twisted blades (9) having a profile with defined geometric characteristics. A one-piece rotor can be manufactured employing open tools (10a, .. 10n) with slits (5′) formed along a semicircumference, and two passages in succession of the workpiece through the tools, moving the workpiece with a combined motion of rotation and translation. 
     An advantageous application of the so manufactured article is that for a rotor of turbomolecular pumps, since the compression ratio and the pumping speed are optimized and a considerable structural sturdiness of the article is obtained.

Abstract: Semiconductor chips (2) are mounted on and resin-sealed in island  portions (11) of lead frames (1) fabricated from a strip of substrate material (10). The lead frame material (10) is a strip of copper or copper alloy sheet, which has high thermal conductivity, and is spot-clad with metal foils (11) of low thermal expansion by roll-bonding. The foils (11) are located along the substrate at positions opposite where the semiconductor chips (2) are to be mounted, forming island portions (11). Foils (11) may also be spot-clad on the side where the semiconductor chips (2) are to be mounted. Damage to the chips (2) resulting from heating during operation, such as warping or peeling, is thereby effectively prevented.

Filed: 1990-01-30
Abstract: Le PTFE (polytétrafluoréthylène) polymérisé en dispersion, s'il est à l'état non fondu, est capable de faire office d'adhésif sensible à la pression facilitant la formation d'une liaison mécanique initiale entre des constituants d'un stratifié qui pourra ensuite être relativement rapidement chauffé pour devenir un stratifié final solidement lié. Cela permet de préparer un stratifié comprenant au moins une couche contenant du PTFE par les étapes consistant (a) à préparer un premier constituant de stratifié de dimensions stables présentant deux surfaces principales, dont l'une au moins comporte une couche exposée comprenant du PTFE non fondu; (b) à préparer un second constituant de stratifié de dimensions stables présentant deux surfaces principales, dont au moins une est capable de former une liaison complète avec la couche contenant du PTFE non fondu; (c) à joindre lesdits premier et second constituants de stratifié, de sorte que la couche exposée comprenant du PTFE non fondu et la surface qui peut être liée avec la surface contenant du PTFE non fondu soient en contact l'une avec l'autre; (d) à appliquer une pression sur les constituants combinés du stratifié à une température modérée afin d'obtenir un contact intime et d'obtenir une liaison mécanique entre les premier et second constituants de stratifié; (e) à introduire le stratifié lié mécaniquement dans une zone de chauffage dans des conditions évitant la déstratification; et (f) à fritter les constituants du stratifié liés mécaniquement dans une zone de chauffage afin de consolider la couche contenant du PTFE non fondu. La liaison mécanique ainsi formée est suffisamment solide pour que la consolidation ait lieu selon un procédé de frittage libre (sans appliquer de pression). L'application de pression n'est cependant en général pas préjudiciable au produit.

Abstract: The preamplifier includes a first amplifier stage (M1A, M2A) and a second amplifier stage (M1, M2), both of which are of the differential type, have the same dimensions, have their output nodes connected in parallel to one another, and drive a load formed by a current mirror (M3, M4). A third differential amplifier stage with single-ended output (M6, M7, M8, M9, M10, M11) driven by the current mirror supplies the final output voltage of the preamplifier. The input nodes of the first stage act as input for the differential signal to be amplified, and the input nodes of the second stage are driven respectively by a preset reference voltage (V CM ) and by a voltage (V x ) which is proportional to the final output voltage of the preamplifier. A negative voltage-current feedback is thus obtained, due to the fact that a difference in current is generated between the respective output nodes of the first and second stages; the difference is proportional to the difference between the input signal to be amplified and the difference between the reference voltage and the voltage which is proportional to the final output voltage (V x  - V CM ).
