Abstract: PCT No. PCT/US82/01609 Sec. 371 Date Jul. 9, 1984 Sec. 102(e) Date Jul. 9, 1984 PCT Filed Nov. 12, 1982 PCT Pub. No. WO84/02006 PCT Pub. Date May 24, 1984.A continuously variable optical delay line having a first substrate (66, 70) and a second substrate (95). The first substrate is composed of a quartz block (70) with a large radius of curvature along its length, supporting a silicon substrate (66) having a plurality of longitudinal, parallel v-grooves (68). A single length (121) of single mode optical fiber is wrapped around the first substrate (66, 70) in helical fashion with each loop being secured in one of the v-grooves (68). The portions of the fiber (121) in the v-grooves (68) are lapped and polished to create a flat coupling surface extending laterally and longitudinally across the first substrate (66, 70). The second substrate (91) is composed of a quartz block with a single v-groove holding a segment of single mode fiber (95). The radius of curvature of this v-groove is substantially smaller than that of the first substrate, such that the flat coupling surface of the second substrate (91) is shorter than that of the first substrate (66). The first and second substrates are placed together such that the fiber in the second substrate is coupled to the fiber in the first substrate. By moving (142) the second substrate longitudinally with respect to the first substrate, a continuously variable delay can be obtained. The continuously variable delay line can be combined with a separate discretely variable delay line to create a longer continuous variable delay. The continuous variable delay line can be formed with only one v-groove (68) in the first substrate (66).

Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor (13) and a transmission input speed sensor (31) and develops a clutch actuation signal controlling a clutch actuator (27) from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch (20) in a manner to cause the measured transmission input speed to asymptotically approach engine speed employing an approximate inverse model of this oscillatory response. The automatic clutch controller preferably includes a PID function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a PID regulator (65) responsive to the difference of engine speed and transmission input speed, a prefilter (68) operating on the resulting PID signal, and a compensator (70) constructed to reduce the need for detailed particularization for individual vehicles or vehicle models by reducing the system closed loop sensitivity to vehicle parameter variations. <IMAGE>

Abstract: The invention relates to a process for joining overlapping aluminium parts forming a solder gap between them by soldering with a solder suitable for an Al/Al as the filler and a flux, in which first of all a quantity of filler and flux corresponding to the solder requirement is deposited near the visible start of the solder gap and then the aluminium parts are heated for long enough for the filler to melt and creep into the solder gap, whereupon heating is stopped. The feature of the process of the invention is that a region of the visible start of the solder gap and the deposited filler and flux is continuously and contactlessly monitored during heating and the heating adjusted as soon as a control pulse triggered by the sensor has recorded the melting of the filler or the flux.

Abstract: "DISPOSITIVO DE ACIONAMENTO ELéTRICO DE UMA BICICLETA ELéTRICA", que refere-se a um dispositivo elétrico para uma bicicleta elétrica, utilizando o método de contato direto com o pneu, o qual aciona o pneu através de fricção de pressão; os elementos do suporte principal sustentando o rolo de acionamento em contato com o pneu são instalados para rotacionar em operação e para também serem fixados ao tubo de assento da bicicleta. Ao colocar em contato o rolo de acionamento com o pneu, através de uma mola, a roda da bicicleta pode girar com uma força de fricção mínima, dependendo da condição de rodagem, pela disposição dinâmica entre o centro da roda, o ponto de contato do rolo de acionamento e o pneu e um ponto de articulação que serve como um centro rotacional, e, neste momento, o rolo de acionamento pode ser mudado automaticamente pelo ajuste automático da pressão entre o pneu e o rolo de acionamento com a pressão de fricção mínima sendo capaz de girar a roda, dependendo da condição de rodagem, de modo que o consumo de energia elétrica é reduzida para evitar um funcionamento livre do rolo de acionamento.
