IPC: H03M7/30
Filed: 2021-05-07
Abstract: DESCOMPRESSÃO EM LINHA. Técnicas e aparelhos para descomprimir dados que foram comprimidos em pilha são descritos. A compressão de pilha refere-se à compressão de dados em uma ou mais dimensões. Para blocos de dados não comprimidos que são muito esparsos, ou seja, blocos de dados que contêm muitos zeros, a compressão de pilha pode ser eficaz. Na compressão de pilha, o bloco de dados não comprimido é comprimido no bloco de dados comprimido removendo uma ou mais palavras zero do bloco de dados não comprimido. Um metadados de mapa que mapeia as palavras zero do bloco de dados não comprimido é gerado durante a compressão. Com o uso dos metadados de mapa, o bloco de dados comprimido pode ser descomprimido para restaurar o bloco de dados não comprimido.

Title: Process for producing extremely pure plaster and apparatus for making the same
Inventor: RAGNARSSON SVEN
IPC: B01D53/68
Filed: 1994-10-26
Abstract: A method and a device are employed for producing high-purity gypsum from a sulphur-dioxide-containing gas (1), such as a flue gas, which contains impurities in the form of heavy metals and preferably hydrogen chloride as well. In a primary circuit (23) in a sulphur-dioxide-absorption stage, the gas (1) is washed with a wash solution, preferably based on sodium, for absorbing sulphur dioxide and heavy-metal impurities, whereupon a partial flow of the wash solution is withdrawn from the primary circuit (23) and regenerated in a secondary circuit (31) by the addition of a calcium-ion source (36), such as slaked lime, for precipitation and separation of pure gypsum, and by the addition of a carbonate-ion source (42), such as soda, for precipitation of carbonate. The method and the device are distinguished by the fact that a sulphide-ion source (43), such as sodium sulphide, is added to the partial flow after the calcium-ion source (36), preferably at the same time as the carbonate-ion source (42). The sulphide-ion source (43) is added to the partial flow at a high pH value, conveniently 8-14, preferably about 11-14, and most preferred about 13. When the sulphur-dioxide-containing gas (1) contains a further impurity in the form of hydrogen chloride, the device comprises a hydrogen-chloride-absorption stage. In that case, the material precipitated upon the addition of the carbonate-ion source (42) and the sulphide-ion source (43) is preferably conducted to the hydrogen-chloride-absorption stage.

Abstract: The invention consists of a multilayer material and a process for manufacturing this material. The multilayer material comprises a polyester substrate which is provided with a thermoset plastic polymer coating and a layer of contact adhesive. The polymer coating is produced by a reaction between a polyurethane polymer containing hydroxyl groups and a low molecular linear polyisocyanate, with catalytic tin-organic additives and colorants. The multilayer material is resistant to tearing and is also weather-resistant. A transparent, reactive layer, consisting, for example of a layer to take toner or ink, or a metallic layer, can be deposited on the side opposite to the polymer-coated substrate. Multilayer materials of this kind are suitable for large-scale covering of supporting frameworks in the construction of model aircraft and are also suitable as a medium onto which images and print may be applied using a plain paper copier, and can also be used to carry advertising.
