Title: Impulsor eólico para rodas de aeronaves.
Inventor: ENCARNACAO FERNANDO ANTONIO FR
IPC: B64C25/40
Filed: 1999-02-19
Abstract: Certificado de Adição para a Patente de Invenção do ''Impulsor Eólico para Rodas de Aeronaves''. O presente certificado de adição se aplica ao ''Impulsor Eólico para Rodas de Aeronaves'' e diz respeito a uma mudança no posicionamento das aletas (1) que compõem o plano de captação de energia do impulsor. O aperfeiçoamento tem como base a incorporação das aletas (1) nas laterais do próprio pneu, o mais próximo possível da banda de rodagem. As ditas aletas (1) são peças com um desenho aerodinâmico que capta energia eólica a partir da resistência do ar (gerada pelo atrito, devido ao deslocamento da aeronave) para romper a inércia e imprimir uma certa rotação aos pneus do trem de aterrissagem de tal modo que, ao tocar o solo todos os pneus já estejam numa rotação igual ou muito próxima aquela requerida pelo deslocamento da aeronave no momento do pouso. Pousar uma aeronave com as rodas em absoluto estado de repouso (como ocorre hoje) corresponde a um travamento instantâneo das rodas. Se o travamento das rodas de um automóvel pode provocar a perda total de controle sobre a trajetória do veículo, numa aeronave pode certamente provocar a perda da rota no exato momento em que esta tocar o solo. Isto pode explicar, em parte, os inúmeros acidentes nas operações de pouso das aeronaves. Esta invenção, aparentemente simples, é capaz de propiciar um pouso muito mais suave, reduzir o desgaste na estrutura do trem de aterrissagem e reduzir o desgaste e a deformação prematura dos pneus além de proporcionar maior estabilidade da aeronave quando esta tocar o solo. O dito impulsor é constituído pór um plano de captação de energia eólica, formado pór um conjunto de aletas (1) com uma forma aerodinâmica capaz de gerar uma força suficiente para romper a inércia e imprimir uma certa rotação às rodas do trem de aterrissagem, logo que este seja acionado no início dos procedimentos para o pouso. Este certificado de adição prevê que as ditas aletas (1) são fundidas diretamente nas laterais do pneu (2) o mais próximo possível da banda de rodagem do pneu.

Title: Method and circuit arrangement for the protection of a heated temperature-dependent sensor resistor against overheating
Inventor: SCHIFFERL LUDWIG DIPL ING
IPC: G01F1/698
Filed: 1993-09-23
Granted: 1994-12-01
Abstract: Arranged in the induction tract of an internal combustion engine are a temperature sensor resistor (Rt) and a sensor resistor (Rh). These two resistors belong in each case to one bridge arm of a measuring bridge, whose bridge diagonal is led to a differential amplifier (OP1). In this arrangement, the current in the bridge is adjusted such that the sensor resistor (Rh) always has a predetermined overtemperature. Because of back fires in the induction tract, damage to the sensor resistor (Rh) can occur because of a sudden severe heating of the temperature sensor resistor (Rt) as a result of a severe current rise. In order to avoid this, a third bridge arm (R4, R5) is connected in parallel with the two bridge arms, the tap B of the third bridge arm and a tap A being led to the inputs of a second differential amplifier (OP2), whose output signal influences the bridge current in order that the current is limited to a predetermined value. <IMAGE>

Abstract: Hitherto, waste gases were conditioned by the catalytic conversion of sulphur dioxide into sulphur trioxide and introduction of the sulphur trioxide into the waste gas flow. The particles entrained in the waste gas were then deposited in an electrostatic filter (3). The sulphur trioxide is introduced in a novel manner in that, before entering the electrostatic filter (3), the waste gas is guided through a gas discharge section (4) having coronae. In the coronae, OH radicals are generated from the water vapour entrained in the waste gas and react with the sulphur dioxide which is still present in the waste gas to form sulphur trioxide. The latter in turn reacts with water vapour to form sulphuric acid which condenses on the particles and increases the electrical conductivity of the filter cake deposited on the deposition electrodes of the electrostatic filter. In this way, the deposition capacity of the filter is considerably improved, even when waste gases from low-sulphur fuel combustion plants are purified, without chemicals having to be added to the waste gas.
