Patent BR-8802365-A (BR)
Inventor: SOLLINGER HANS-PETER
IPC: B05C11/00
Filed: 1988-05-09
Abstract: The metering mechanism positioned against a counter-roller and located behind, with respect to the running direction of the material web, a pre-coating facility features a slit 14 on the feed side of a balancing chamber 1 formed on a front wall 4 to the counter-roller 2 and extending over the width of the web. The front wall 4 is provided with discharge channels 10 extending in the manner of a slit across the width of the web, which can be throttled by a rotary disc valve 7. In this way, an outflow from the balancing chamber 1 can only occur through the discharge channels 10, while only the coating material from the material web can be introduced through slit 14 into the balancing chamber but no coating slip emerges from the balancing chamber. <IMAGE>

Abstract: A voltage-to-digital converter comprising a storage circuit for providing a storage capacitance with a plurality of selectable magnitudes. The storage circuit provides a charge output representative of applied voltage input signals and the selected capacitive magnitude. A charge accumulation circuit is coupled to the charge output. The total charge accumulated is proportional to the integral of the amount of charge discharged from the storage circuit. The charge accumulation circuit provides a balance output representative of a comparison of the accumulated charge and a reference charge. A control circuit is coupled to the balance output for providing feedback signals as functions of the balance output for periodically charging and discharging the storage capacitance whereby a first sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference within a first set of limits when a first capacitive magnitude is selected in the storage circuit and whereby a second sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference charge within a second set of limits when a second capacitive magnitude is selected in the storage circuit. A calculation circuit is coupled to the feedback circuit for counting the number of charged packets generated in a measurement cycle. An output circuit provides an output indicative of the voltage input signals as a function of the number of packets counted.

Abstract: In the so-called cyanidation-in-mill technique, the ores, ore concentrates and gangue material, which are to be leached, from previous incomplete leachings are treated with a cyanide-containing leaching solution already in the mill, gold and silver being leached out at least partially. As compared with the previously known cyanidation-in-mill technique in the presence of hydrogen peroxide, the gold yield can be substantially increased if the leaching is carried out in the presence of a peroxoborate compound. The peroxoborate can be present in a solid and/or dissolved form. Preferably 10 to 60 equivalents of peroxoborate are used per tonne of the material to be leached.

Abstract: A highly controllable way to light target areas includes a primary reflector (34) which generates a defined primary beam (40) in association with a light source (30). The primary beam (40), or at least a portion of the primary beam, is directed onto a secondary reflector (42) which generates a secondary beam (44) to the target space. The secondary reflector (42) can be configured in any number of contours, shapes, specularities, or other characteristics to alter and control the characteristics of the secondary beam (44). Various options, alternatives, and features are possible with the invention. For example, a plurality of light sources (30) and primary reflectors (34) can be used with one secondary reflector (42). The surface of the secondary reflector (42) can be corrugated to have alternating segments to direct light in different directions. A combination of light source (30), primary reflector (34), and secondary reflector (42) can also be positioned on a moveable base. A plurality of secondary reflectors (42) and light sources (30) and primary reflectors (34) can be positioned on one moveable base and can be oriented in different configurations for different lighting effects. The invention can be used to light a variety of areas, including highways, spectator events and locations where significant control of light is needed. <IMAGE>

Abstract: Solid films with novel optical properties are produced from colloidal suspensions of cellulose crystallites; the colloidal suspensions are prepared by acid hydrolysis of crystalline cellulose under carefully controlled conditions; the solid materials possess a helicoidal arrangement of the constituent crystallites; by appropriate selection of conditions for preparation and treatment of the colloidal suspensions, solid films are produced that reflect circularly polarized visible light; the wavelength of the reflected light can be controlled to give colours across the visible spectrum from red to violet, and if necessary to infrared and ultraviolet wavelengths. The reflected iridescent colours arise from optical interference effects, and change with the viewing angle; this makes the materials ideally suited for optical authenticating devices, since no printing or photocopying technique can reproduce this effect; furthermore, they are easily distinguishable from other optical interference devices since they have additional optical properties.

Abstract: <B>"PROCESSO DE PRODUçãO DE FERRO GUSA NODULAR ESPECIAL, A SOPRO SUBMERSO-PGNESS".<D> Primeiramente o ferro gusa é vazado do alto forno para um reator (panela ou similar), no qual ao mesmo são feitas adições de desfosforantes - cal, ou carbonato de cálcio, ou carbonato de sódio ou fluoreto ou cloreto de cálcio ou uma combinação destes-, além de substância contendo óxido de silício (composto escorificante do manganês) tais como areia, quarzito, etc - para a obtenção do ferro gusa nodular, caracterizado pelo baixo teor de fósforo e manganês - inferiores a 0,05%.  em seguida o banho é submetiodo a oxidação e agitação pela injeção de oxidante (ar ou oxigênio) atra'ves de um plug refratário porosop submerso ao banho no rator, e, ao mesmo tempo o banho metálico é submetido a oxidação pela superfície atra'ves da injeção de oxigênio via lanças próprias - tubos de aço revestidos de material refratário ou tubos de cobre refrigerados. Após a injeção de oxigênio pela superfície do banho, em quantidade cerca de 20% superior à estequiometricamente calculada, superfície para promover as oxidações necessárias dos elementos a serem oxidados, esta é interrompida,mantendo-se a injeção de oxidante pelo plug poroso submerso no banho metálico com a finalidade de manter o ambiente oxidante para evitar reverter o metal o fósforo e ou o manganês, retidos na escória.  Com este procedimento conseguimos eliminar o fósforo e o manganês do ferro gusa simultaneamente através de uma escorificação em uma única etapa, possibilitando a viabilização técnica e económica para a obtenção do ferro gusa nodular especial, partindo-se de ferros gusas com elevado teor de manganês(de até 1% de Mn), ferros gusas estes obtidos à partir de minérios de ferro com elevado teor de manganês, uma vez que os minérios que associam teores de fósforo e manganês baixos(inferiores a 0.07%) estão cada vez mais escassos, minérios estes essenciais à aplicação no processo de produção de gusa nodular tradicional o qual só pode utilizar exclusivamente este tipo de minério..
