Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound; the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.

Abstract: A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state. The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10 DEG C to 95 DEG C, preferably about 20 DEG C to 40 DEG C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution. The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide. The copper in the leaching solution after further processing is subsequently recovered by electrowinning. The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper. <IMAGE>

Abstract: A method for the manufacture of one-piece tape tabs to be used with disposable absorbent articles. The first step is to provide a backing substrate upon which the pressure-sensitive adhesive of the tape tab can be applied. Once the backing is provided, the pressure-sensitive adhesive is applied to regions of one side of the backing substrate. The backing substrate is then slit in a direction parallel to the machine direction forming tape tab stock that is preferably fed directly to the taper unit of the absorbent article manufacturing line. The taper unit cuts the tape tab stock comprising the pressure-sensitive adhesive into individual tape tabs, each having a fixed end and releasable end. The fixed end of each tape tab is joined to the chassis of an absorbent article by means of mechanically bonding the fixed end to the absorbent article. The mechanical bonding not only joins the fixed end of the tape tab to the absorbent article, but also forms a region on the outwardly facing surface of the fixed end of the tape tab that acts as a release surface for the pressure-sensitive adhesive. In preferred embodiments, an area of the absorbent article adjacent to the fixed end of the tape tab is also subjected to mechanical bonding. The mechanical bonding forms a region on the surface of the absorbent article that acts a release surface for the pressure-sensitive adhesive disposed on the releasable end of each tape tab.

Title: Método e kit para detecção de fatores reumatóides em lìquidos biológicos

IPC: G01N33/68
Filed: 1997-06-25
Abstract: "MéTODO E KIT PARA DETECçãO DE FATORES REUMATóIDES EM LìQUIDOS BIOLóGICOS". O fator reumatóide é detectado no soro, dentre outros métodos, usando-se partículas de látex recobertas com imunoglobulinas G (IgG) humanas, alteradas ou através do uso de hemácias de carneiro sensibilizadas com IgG de coelho anti-hemácia de carneiro, em dose sub-aglutinante. O fator reumatóide, que é um anticorpo dirigido contra a IgG humana, reconhece determinantes antigênicos na região Fc da IgG humana alterada e também reconhece epitopos ou determinantes antigênicos sobre a IgG de coelho. Assim, ambos os sistemas podem ser usados para a detecção de fatores reumatóides. O primeiro método é muito sensível e pouco específico, enquanto o segundo é altamente específico mas pouco sensível, além de necessitar de longos períodos de incubação. O método que origina o KIT associa a sensibilidade do primeiro com a especificidade do segundo. Isto foi possível pelas modificações introduzidas, tanto na etapa de desnaturação da IgG humana ou de coelho, quanto nas etapas de sensibilização do suporte sólido, como por exemplo o látex. No método que origina o KIT, as imunoglobulinas G são fortemente desnaturadas pelo calor (incubação de 50 a 65<198>C.) e por agentes químicos do grupo da uréia (nas concentrações que variam 2 a 8M) em presença de agentes redutores (da família do 2-mercaptoetanol em concentrações que variam de 0,01 a 2,5M), originando cadeias polipeptídicas monoméricas da IgG: as cadeias H+L. Estas cadeias desnaturadas e na forma agregadas ou não, são utilizadas para sensibilizar um suporte físico, o látex por exemplo, da seguinte forma: misturar cerca 1 volume de tampão do tipo borato (pH 5,5 a 9,5) contendo IgG desnaturada com cerca de 25 a 450<109>l de partículas de látex, e a seguir submeter a mistura a seguidos ciclos de incubação prolongada em diferentes temperaturas. Desta forma, a IgG desnaturada como descrito é adsorvida ao látex ou a outro suporte físico que adsorve proteínas, originando partículas sensibilizadas, que em presença de fator reumatóide sofrem aglutinação. O Kit originado pelo processo contém partículas sólidas (que como exemplo foi usado o látex) sensibilizado por IgG desnaturada segundo o método proposto. é também acompanhado de controles positivos e negativos. O Kit originado pelo método caracteriza um aperfeiçoamento em relação aos demais Kits pela sua alta sensibilidade e especificidade. A inovação apresentada pelo Kit está relacionada ao novo processo de desnaturação da IgG e às modificações nas etapas de sensibilização do suporte sólido, caracterizando um avanço metodológico.
