Title: Système de transmission de données entre des stations connectées en boucle
Inventor: BARNER ROBERT PAUL
IPC: H04L12/433
Filed: 1978-12-08
Abstract: Système de transmission de données numériques par trames entre une pluralité de stations connectées en série selon une configuration en boucle unidirectionnelle. Le système est constitué d'une pluralité de stations indentiques (1, 2...16) connectées par un bus principal (17) et par deux bus alternés (18) l'un des bus connectant les stations d'ordre pair et l'autre les stations d'ordre impair, de façon à permettre l'évitement d'une station défectueuse. Les données en provenance ou à destination de processeurs (21, 22...36) connectés aux stations sont transmises sur la boucle sous forme de trames transitant par toutes les stations se trouvant entre la station d'origine et la station de destination, permettant à n'importe quelle station de pouvoir éliminer les trames erronées. Lorsqu'une station a reçu une trame qui lui était destinée, elle renvoie une trame de réponse et des trames nulles circulent sur la boucle en l'absence de trames de données.

Abstract: The system includes a variable aperture transducer unit having a linear array of ultrasonic transducer elements, which are subdivided into groups. Each group of transducer elements, during echo reception, defines a distance dependent reception sensitivity pattern having a near field and a far field which meet in a transition zone. Reception resolution is best in the transition zone. The distance of the transition zone from the transducer unit is a function of the size of the variable aperture, which size is defined by the number of transducer elements applied for reception at a given time. To take advantage of this phenomenon, the system also includes dynamic aperture control circuitry for expanding the transducer unit aperture with time during echo reception by successively adding adjacent transducer elements to the receiving group causing the high resolution transition reception zone to recede into the subject generally coincident with an ultrasonic energy burst.

Abstract: The packages are weighed at a first weigh station (16,17) to determine whether they fall within a predetermined weight range or whether they fall within predetermined limits either side of said predetermined weight range. If the latter the packages are then fed to a second weight station (23, 28) at which they are again weighed and according to the weight ascertained there, an operator is given an indication usually by lights as to the exact number of make weight pieces both in number and size which have to be added or subtracted to the package in order that the package shall then fall accurately within the predetermined weight range. The second weigh station (23,28) is desirably controlled by a computer which is supplied with basic information such as:
     (a) the stated package weight   (b) the average number of articles per pack   (c) the predetermined make weight ranges and other factors.

Abstract: Le procédé et l'installation concernent l'initialisation de la sécurisation d'une ligne normale (1) parmi N d'une artère de transmission numérique bidirectionnelle comprenant au moins une ligne de secours (1s). L'artère est interconnectée entre deux stations d'extrémité (A,B) qui permettent la commutation d'une ligne normale défectueuse avec une ligne de secours.

Abstract: Un moteur a induction a courant alternatif (16) pour entrainer une charge mecanique variable est mu via un commutateur Triac (20) monte electriquement en serie avec le moteur et son alimentation a courant alternatif. Une resistance a faible valeur ohmique (27), montee egalement en serie avec le moteur, echantillonne de maniere continue le courant de la charge. Lorsque la valeur maximum du courant de charge echantillonne est inferieure a une valeur predeterminee indiquant des conditions proches de la pleine charge, le Triac est commute vers un etat de conduction avec un angle electrique predetermine a partir de chaque bord de fuite precedant immediatement des impulsions de courant de charge echantillonees ou des impulsions de la tension de lignes echantillonnees appliquees au moteur. Un tel systeme de commutation de declenchement de phase reduit l'energie appliquee au moteur en reduisant la periode de temps de chaque demi cycle de tension d'alimentation appliquee au moteur qui, a son tour, reduit les pertes causees par le courant reactif dans le moteur a induction de charge inferieure a la pleine charge. A pleine charge ou pres de la pleine charge, le Triac est maintenu ou verrouille dans un etat de conduction pour appliquer de maniere continue la tension d'alimentation totale au moteur.

Eine schnelle, gleichmässige und wirtschaftliche Zündung wird dabei dadurch erreicht, dass in den oberen Bereich des Zündofens Rauchgase aus einem oder mehreren näherungsweise stöchiometrisch betriebenen Brennern zugeführt werden und dass in den unteren Bereich Gase mit einem erhöhten Sauerstoffanteil zugeführt werden, dergestalt, dass sich eine Ofenatmosphäre ergibt, die im oberen Bereich der Zündhaube heisser und sauerstoffarmer, im unteren Bereich kühler und sauerstoffreicher ist.

Abstract: Logic gates employing enhancement mode Schottky diode metal semiconductor gate (MESFET) gallium arsenide (GaAs) devices are difficult to fabricate because of variations in their threshold voltages which must be overcome by very tight control in order to fabricate uniform, very thin active channel layers, so that they are totally depleted at zero gate bias voltage and yet give good device transconductance when the device is turned on. 
     A logic gate is disclosed employing enhancement mode MESFET gallium arsenide devices which do not require the tight process control because two such devices (2, 7) are employed in the gate circuit to mutually compensate for the effects of their equal deviation from nominal threshold voltages.
