Abstract: A synchronizing circuit including an oscillator (OS), a phase discriminator (PD) having a first input coupled to an input terminal of the circuit (SP) for receiving an incoming synchronizing signal, a second input for receiving a signal derived from the oscillator (OS) and an output for applying a control signal to a control input (30) of the oscillator (OS) for controlling the frequency and/or the phase of the oscillator signal. To ensure that the action of the circuit is not disturbed when no signal is present at the input terminal of the circuit, the circuit includes an auxiliary circuit for reducing the difference between the signal at the output of the phase discriminator and a reference, the auxiliary circuit (AC) being active in response to a synchronizing signal detector at the output of the phase discriminator (PD) in the absence of the incoming synchronizing signal and inactive in the opposite case.

Abstract: PCT No. PCT/GB90/01416 Sec. 371 Date Apr. 20, 1992 Sec. 102(e) Date Apr. 20, 1992 PCT Filed Sep. 13, 1990 PCT Pub. No. WO91/04617 PCT Pub. Date Apr. 4, 1991.An optical detector for use in detecting digital optical signals has an optical fiber coupler which splits a received optical signal into two signal portions. The coupler has unequal length output fibers so that one signal portion impinges upon an associated photodetector delayed relative to the other. The photodetectors are connected in series nonopposed when the delay is equal to the bit period of the optical signal the output of the detector is the differential code (dicode) of the received signal which can be recovered by a high input impedance, i.e. integrating, amplifier. By forming the dicode in the optical domain in this manner large DC and AC dynamic ranges are obtained without linearity constraints on the optical transmission source that apply when the optical signal is transmitted as a dicode.

Abstract: A method and apparatus is provided for modifying fiber or fabric by fatiguing that creates at least one of the following characteristics including: axially aligned cracks, physical change created by the bending and compression of the fiber along the fiber's longitudinal axis taking the form of kink bands, enlarged segregated fibular tangles or enlarged nodes. Fatiguing is defined as repeated stress on fiber by high velocity impact that bends the fiber and compresses it in a direction parallel to the fiber's longitudinal axis. Fatiguing results in softer hand and/or improved dyeability in some fabrics, including but not limited to liquid crystal fabrics and cellulosic vegetable fabrics. The application of one or more gas jets directed away from the interior curved surface of a cylinder, generating a vortex which rapidly and repeatedly cycles the substrate at low tension past the gas jets. The rapid vibrations generated in the substrate by the jets serve to break apart fiber to fiber bonds caused by finish and loosen up the structure of the yarns and that of the substrate. This creates a desired aged appearance as well as a very soft texture.

Abstract: Système audio monté sur une automobile. Un dispositif de reproduction acoustique comprend un circuit de commande équilibreur qui distribue les signaux acoustiques parmi des canaux prédéteminés et qui ajuste le niveau des signaux acoustiques distribués selon la position d'une commande d'équilibrage. Un dispositif de commande du champ acoustique traite les signaux acoustiques transmis par le circuit de commande équilibreur afin d'établir un champ acoustique voulu dans l'enceinte de la voiture. Un dispositif annule la distribution des signaux acoustiques effectuée par la commande d'équilibrage pendant que le dispositif de commande du champ acoustique est en fonctionnement. Lorsque le dispositif de commande du champ acoustique est branché, les effets d'une commande d'équilibrage et de balance sont éliminés, et par conséquent leur champ acoustique également. Le champ acoustique est ainsi automatiquement ajusté en position centrale même lorsque les commandes respectives s'écartent de leur position centrale. Le dispositif de commande du champ acoustique peut ainsi obtenir des effets maximum.
