Abstract: "SISTEMA E MéTODO PARA DESENHAR UM ARCO ELìPTICO". São descritos um sistema e um método interativos de controle de arco elíptico. São providos três pontos de controle - um ponto de controle de centro e dois pontos de controle de foco - que um usuário pode manipular interativamente de modo a especificar e mudar os parâmetros elípticos envolvidos. O ponto de controle de centro pode controlar o raio da elipse na direção x, mantendo constante a razão do raio da elipse na direção y para o raio da elipse na direção x. O ponto de controle de centro pode também controlar a relação do flag de varredura para o flag de arco maior. Os dois pontos de controle de foco podem controlar a razão do raio da elipse na direção y para o raio da elipse na direção x, o ângulo do eixo x do sistema de coordenadas com o eixo x da elipse e o valor do flag de varredura.

Patent BR-0309275-A (BR)
Inventor: PRING GRAHAM M
IPC: D21H19/40
Filed: 2003-01-29
Abstract: The present invention provides high brightness kaolins exhibiting a Brightness (GE) of at least about 90.0. The hydrous kaolin pigments of the present invention may also have,  inter alia,  a steepness index (d 30 /d 70  X 100) of at least about 39 and/or a  titania  concentration less than or equal to about 0.40% by weight of the pigment on a dry basis. The hydrous kaolin pigment is produced by a process comprising: a) forming an aqueous suspension of a hydrous kaolin clay; b) forming a primary product by subjecting the suspension to classification or a combination of classification and griding; c), separating the kaolin from impurities by selective flocculation; and d) defining the separated kaolin. The hydrous kaolins of the present invention allow coated papers to be produced at high brightness while maintaining acidic conditions on a paper machine. The invention pigments exhibit brightness levels unexpectedly higher, e.g., about 2 to about 5.2 or more (GE) units brighter, than exhibited by previous high brightness hydrous kaolin pigments, without sacrificing other important paper properties. Paper coated with the inventive pigments have high brightness, high whiteness, and high fluorescence levels. The present invention encompasses these pigments, compositions comprising them, and any application in which they are used.

Fornecido um método para gerenciar uma área defeituosa de um meio de gravação óptica de gravar uma vez, e um meio de gravação óptica utilizando o mesmo. Em um dispositivo de disco ótico para gravar/reproduzir dados utilizando um disco ótico como um disco do tipo BD WO, o método permite a leitura normal e reprodução de dados de gravação gravados em uma área defeituosa do disco, através de uma operação de gravação de substituição para a gravação de dados da área defeituosa. Quando um defeito é detectado em um setor de gravação predeterminado do disco ótico durante o processo de gravação, os dados de gravação são gravados em uma área reserva que corresponde à área defeituosa e os dados desse modo gravados são gerenciados. Para realizar isso durante a gravação de dados, o método pesquisa seletivamente um local de gravação de informações de lista de defeitos temporários (TDFL), que é efetivo antes da finalização de disco, ou informações de lista de defeitos (DFL), que se tornam efetivas após execução de uma operação de finalização de disco. As informações TDFL são gravadas em um setor de gravação designado e incluem um ou mais localizadores de dados de área defeituosa indicativos de áreas defeituosas como detectado. Informações de local de gravar e informações de identificação permitem a pesquisa seletiva das informações DFL após finalização de disco e são gravadas, juntamente com as informações DFL, como informações de definição de disco em uma área de gerenciamento de defeito designada para a área de entrada do disco.

Abstract: Methyl tert-butyl ether (MTBE) is prepared by the selective reaction of methanol with isobutylene contained in a hydrocarbon fraction with four carbon atoms (C4fraction, or C4hydrocarbons), operating in the liquid phase under the influence of acid catalysts. The reaction mixture containing MTBE together with methanol and C4hydrocarbons is distilled, preferably at increased pressure, with separation of the methanol and the C4 hydrocarbons at the head and of MTBE at the bottom of the distillation column. This operation is carried out with an additional lateral liquid flow of a C4 hydrocarbon, or mixture of C4 hydrocarbons, to the column so as to maintain a methanol-C4 hydrocarbon composition in the column at all times with a greater than azeotropic C4 hydrocarbon content at the operating pressure. According to a preferred embodiment the distilled C4 hydrocarbons, after separation from the methanol, are recycled as the lateral flow to the distillation column. It is thus possible to separate MTBE completely in a single distillation operation with a high purity as the product at the bottom of the column.
