Abstract: "DISPOSITIVO ELIMINADOR DO RUìDO DO GOTEJAMENTO DE áGUA PROVINDA DO FUNCIONAMENTO DE APARELHOS DE AR CONDICIONADO". Patente de invenção para um dispositivo eliminador do ruído do gotejamento de água provinda do funcionamento de aparelhos de ar condicionado, que visa principalmente a eliminação do ruído/barulho provocado pelas gotas que saem do aparelho de ar condicionado caindo sobre outros aparelhos. A água gerada no interior do aparelho de ar-condicionado 20 é eliminada de seu interior através do tubo de escoamento 21. Essa água em forma de gotas 22, pela força da gravidade, cai sobre o dispositivo eliminador do ruído do gotejamento de água provinda do funcionamento de aparelhos de ar condicionado 10, composto por uma estrutura metálica quadrada/retangular 13, de comprimento e largura variáveis de acordo com o tamanho do aparelho de ar-condicionado, e altura variando de 2 a 4 centímetros contendo em seu interior uma tela metálica 12 com furos milimétricos revestida por outras duas telas 11, plásticas, também com furos milimétricos, perfazendo assim três camadas de telas, equidistantemente distribuídas, no interior da estrutura metálica 13. A gota 22 ao chocar-se com a primeira tela plástica 11 é fracionada em gotas menores, o mesmo acontecendo quando essas se chocarem com a tela metálica 12 e novamente com a outra tela plástica 11. O princípio que rege a presente patente apóia-se na utilização do peso da gota para agir como um fator a impulsioná-la ao encontro dos furos da tela, que por serem milimétricos, em vez de fornecer resistência e retê-la, atuarão num processo de dispersão. As partículas quando chocarem com o aparelho de ar-condicionado 20 não mais provocam ruído/barulho face ao seu peso ser infinitamente pequeno. A estrutura metálica 13 tem presa em uma de suas extremidades uma chapa 15 provida de dois ou mais orifícios 16 para fixar o dispositivo eliminador do ruído do gotejamento de água provinda do funcionamento de aparelhos de ar condicionado 10, com parafusos através dos orifícios 16, na parede externa do edifício 40. O dispositivo eliminador do ruído do gotejamento de água provinda do funcionamento de aparelhos de ar condicionado 10, é um objeto para ser usado sobre diversos tipos, marcas e tamanhos de aparelhos de ar-condicionado, que além de eliminar o ruído proveniente do gotejamento de água provinda do aparelho de ar-condicionado instalado em andar superior, protege o aparelho da ação direta da incidência dos raios solares uma vez que por serem as telas milimétricas, estas criam uma barreira contra os raios solares (sombra).

Abstract: An apparatus for highly efficiently encoding digital signals by converting input digital signals into signals on a frequency axis in a blocked form, and encoding the input digital signals with a suitable number of assignment bits for each of said blocks to transmit them, wherein the input digital signals are subjected to the orthogonal conversion and are divided by a critical band, encoded with a suitable number of assignment bits based on an allowable noise level, and are subjected to the floating processing. When the floating processing is to be carried out by a plurality of small blocks of a band narrower than the critical band, information of word length of a small block is transmitted out of the small blocks in the critical bands, in order to reduce the bit number for the word length and to compress the bits. Moreover, when the floating processing is to be carried out by small blocks of bands narrower than the critical bands, allowable noise level and information of word length of a small block are transmitted for each of the critical bands instead of transmitting the floating coefficient for each of the critical bands, in order to decrease the number of transmission bits and to highly compress the bits. When the floating processing is to be carried out by small blocks of bands narrower than the critical bands, furthermore, information of a word length corresponding to the number of assignment bits is transmitted, and information related to allowable noise level whose designated range is deviated toward the lower side from the signal level range within the critical band by a predetermined amount of level, is obtained through a quantization table and is transmitted instead of transmitting the floating coefficient, in order to more highly compress the bits. <IMAGE>
