IPC: H02P25/22
Filed: 2002-04-26
Abstract: "MáQUINA ROTATIVA ELéTRICA CONECTADA EM MALHA COM VãO MUTáVEL". A presente invenção refere-se a um aparelho rotativo elétrico, que tem impedância variável. Isso é obtido pela conexão de um dos componentes polifásicos do aparelho em uma conexão em malha. O valor de vão, L, de uma conexão em malha como essa pode ser variado pela mudança do conteúdo harmónico suprido por um componente de inversor. Também é provido um método para a conexão de um inversor a um motor, onde um arranjo de comutação permite a alteração simples entre várias conexões em malha de diferentes valores de vão, mudando-se, desse modo, a relação de Volts / Hertz do motor.

Abstract: Noxious flue gases issuing from a combustion process are treated by a chemical - mechanical process wherein initial condensation of at least a portion of the water vapour present, and intimate mixing of this condensation with a high concentration of alkali and/or alkali salts and the residual gases, results in scrubbing of the flue gases. A major portion of the resulting product is removed from the residual flue gas. The loss in thermal energy of the flue gases in the initial stage of scrubbing may be subsequently compensated by supplementary heating. Additional treatment includes the spraying of a basic substance such as limewash in dispersed relation into the residual flue gases, to eliminate the acidic content of the gases, and to regulate the amount of carbon dioxide in the atmosphere.

Date Apr. 29, 1993A method and apparatus for correcting refractive errors of the eye are disclosed. Accelerated reshaping of the corneal tissue is accomplished by administering one or more enzymes and/or other agents to the eye which temporarily soften the cornea. The cornea is thereafter fitted with a rigid contact lens or a series of lenses which have a concave curvature that will correct a refractive error. The softened cornea then rapidly reshapes its convex curvature to the concave curvature of the contact lens or series of lenses, thereby rendering the eye emmetropic. The enzymes and/or other agents then dissipate from the cornea, and the cornea "hardens" to retain the new emmetropic shape. After "hardening" has occurred, the lens rendering the eye emmetropic is removed.
