Patent BR-8902853-A (BR)
Inventor: WAITE PETER DONALD
IPC: C22B21/06
Filed: 1989-06-14
Abstract: An apparatus and process are described for treating molten metal. The invention comprises: (a) a heated vessel (10) having inlet (11) and outlet (12) means for the continuous flow of molten metal downwardly through the vessel (10), (b) a perforated plate (16) extending horizontally across the vessel dividing it into an upper treatment section and a lower treatment section, this plate forming an intermediate treatment section, and (c) a device for injecting gas in the form of small discrete bubbles into the metal in the lower treatment section, this device comprising a hollow rotatable shaft (20) extending downwardly through an opening (30) in the plate (16) with drive means coupled to the upper end of the shaft (20), a vaned rotor (22) fixedly attached to the lower end of the shaft within the lower treatment section, with one or more passageways within the rotor for conducting gas from the interior of the shaft to the metal in the lower treatment section. When the gas is discharged through the rotor (22) and the rotor (22) is rotated, the gas is injected into the metal in the form of small discrete bubbles (61) which are uniformly dispersed within the lower treatment section. In a preferred embodiment of the invention the gas bubbles move from the rotor upwardly and outwardly in a generally conical pattern (60) to be distributed across the bottom of the perforated plate (16) and pass upwardly through the perforations thereof.

Abstract: Novel gold(I) mercaptocarboxylic acid esters of the formula (I)   <IMAGE>   in which X is a C1- to C3 alkylene group and Z is a group from the series tricyclo(5,2,1,02.6)decane-8- or -9-yl or tricyclo(5,2,1,02.6)decyl-3- or -4-methyl. These esters can be prepared from mercaptocarboxylic acid esters of the formula (II)   <IMAGE>   and from a gold(I) chloride-dialkylsulfide complex. The novel esters can be used in gold preparations for gilding solid bases, especially ceramic materials. Compared to known gold(I) mercaptocarboxylic acid esters, the novel esters result in considerably shorter drying times for gold preparations.

Abstract: A sliding gate valve assembly which has a stationary refractory plate mounted to a mounting plate and secured there by the force pressed against it exerted by another refractory is disclosed. A clamp ring is provided which has extending ears, each of which is bored to ride on a clamp spring assembly. Yieldable means, preferably a coil spring, surrounds the shank of the clamp spring assembly guide shank and engages the underside of the ear and rides in the main frame. When the main frame is closed, pressure is urged on the spring which, in turn, transmits the force to the clamp, the tapered inner edge of which engages the tapered outer edge of the stationary plate. The method of the present invention depends upon utilizing the clamping force of a valve assembly having a main frame and in which yieldable means are provided between the main frame and the mounting plate to urge a continuous clamp ring into engagement with the bandless stationary plate having tapered sidewalls.

Abstract: The clamping device has a base (1) and a work carrier (2) which can be firmly clamped to the base (1) and on which orientation elements (5, 10, 27, 28) are arranged which interact in pairs and orientate the work carrier (2) in three coordinate axes perpendicular to one another and at the correct angle to the base (1). With their clamping force, several clamping members (4, 11) hold the work carrier (2) on the base (1) in the position secured by the orientation elements. Each clamping member has a chuck (4) at the base (1) and a clamping stem (11) at the work carrier (2). There are stop faces (27, 28) opposite one another as orientation elements for securing the position in a coordinate axis (Z) parallel to the line of action of the clamping force. In order to arrange the construction of the work carrier (2) to be as simple and inexpensive as possible, the same, on the side (9) facing the base (1) in the clamped state, has a continuously plane surface which in certain areas forms the stop faces (27) on this side and to which the orientation elements (10) on this side for securing the coordinate axes as well as the clamping stem (11) are fastened. <IMAGE>

Abstract: Patente de Invenção para <B>"PROCESSO DE FABRICAçãO DE PRé-FORMA DE FIBRA óTICA POR DEPOSIçãO DE VAPOR QUìMICO"<D>. Uma pré-forma de fibra ótica é produzida pelo suprimento de reagente de vidro base e de reagente de vidro dopante a um queimador, que gera uma chama na qual uma corrente de partículas de vidro é produzida. O queimador se move com relação a um mandril giratório, para depositar camadas de partículas de vidro no mandril. Durante a deposiçào de uma porção da pré-forma, a taxa de fluxo do reagente de vidro dopante é variada de acordo com uma primeira receita de fluxo de dopante como uma função da posição do queimador a medida que o queimador de move longitudinalmente ao longo do substrato, para formar uma das camadas. A taxa de fluxo do reagente de vidro dopante varia de acordo com uma segunda receita de fluxo de dopante como uma função da posição do queimador que se move longitudinalmente ao longo do substrato para formar uma camada adjacente à outra camada. A segunda receita é diferente da primeira receita, e a taxa de fluxo do reagente de vidro dopante muda durante a etapa de movimento da zona de reação para formar uma camada. Os processos revelados se referem particularmente à produção de pré-forma de diâmetro constante para fibras de decréscimo de dispersão.
