Abstract: A high-speed, high-resolution superconducting counting A/D converter providing greatly increased conversion speeds with a low device count. The superconducting counting A/D converter includes a double-junction SQUID quantizer and a bidirectional binary counter having n stages of four-junction SQUID flip-flops that may be either electrically grounded or floating, where n is the number of bits of accuracy of the counter. The quantizer continuously tracks an analog signal, generating up-count and down-count voltage pulses of the same polarity on two different output lines for increasing and decreasing values of the analog current, respectively. The bidirectional binary counter algebraically counts the voltage pulses, increasing the binary count when up-count pulses are received and decreasing the binary count when down-count pulses are received. Several techniques for reading the contents of the bidirectional binary counter at the end of each sampling interval are also disclosed.

Abstract: Procédé et dispositif permettant de mesurer avec une grande précision l'activité d'oxygène dans le laitier de fonte brute en fusion et dans le laitier d'acier en fusion. Selon le procédé conventionnel de mesure, dépendant de l'élément de concentration d'oxygène composé d'un électrolyte solide du type à tube fermé à une extrémité fixé sur la pointe de la sonde, comportant une électrode de platine de contraste enroulée autour de sa surface externe, et placé directement dans la couche de laitier en fusion, le positionnement de l'élément dans le laitier en écoulement est difficile et le contact de l'électrode de contraste avec la couche de laitier est insuffisant à cause du retrait thermique de l'électrolyte provoqué par la chaleur du laitier, ce qui peut être à l'origine d'erreurs dans la mesure. Au lieu de procéder à la mesure directe de l'activité d'oxygène dans le laitier, le procédé ci-décrit consiste à placer dans le même récipient que le laitier un métal spécifique, dont l'activité d'oxygène s'équilibre avec celle du laitier lorsqu'il est mis en contact avec ce dernier, et l'activité d'oxygène dans le métal spécifique est mesurée afin d'obtenir une mesure indirecte de l'activité d'oxygène dans le laitier. Ce procédé résout le problème que pose le contact insuffisant entre l'électrolyte solide et l'électrode de contraste et garantit une mesure très précise de l'activité d'oxygène dans le laitier.

Abstract: A fire signalling system with ionisation-type smoke detectors (7) which exhibits increased protection against false alarms contains in the fire detectors an ionisation measuring chamber (1) which is connected in series with a linear resistor (2) between two signalling lines (8, 9) which at the same time are used for voltage supply, and electronic means (11, 28) by means of which the operating voltage of the ionisation-type smoke detectors (7) and thus the chamber voltage (Uk) of the ionisation measuring chamber (1) is periodically switched to and fro between the normal value (Ut) which causes a high detector sensitivity and an increased value (Uh) which has the effect that the ionisation measuring chamber (1) operates in the saturation range if possible. By comparing the ionisation current in the ionisation measuring chamber (1) at high (Uh) and at normal (Ut) operating voltage, it is possible to suppress false alarms and to detect the occurrence of smoke even when the radioactive source (10) is covered, for example by dew, since the signal caused by the penetration of smoke predominates.
