Abstract: Abstract This invention prevents the large charging current from flowing to the capacitor at the start of the elevator for preventing damage of the elements of the rectifier device.  Thus the present device provides a control device for an a.c. elevator comprising a commercial a.c. source, a capacitor for smoothing the output voltage of the commercial a.c. source. an inverter for converting the smoothed output voltage of the capacitor into an a.c. power of the variable frequency, an a.c. motor for driving the elevator car by the a.c. power supplied from said inverter, and means for rectifying the voltage of the commercial a.c. source and charging said capacitor by the thus rectified voltage at least when the car is stopped.

Granted: 1986-06-03
Abstract: PRECIS DE LA DIVULGATION           Le procédé consiste à interroger un détecteur de teneur en gaz combustible d'une atmosphère en deux étapes. Dans une première étape le détecteur est alimenté sous une tension faible et on coupe l'alimentation dès qu'un signal positif a été détecté. Dans une seconde étape, si le signal détecté dans la première est négatif ou nul, on alimente le détec-teur sous une tension supérieure à celle utilisée dans la première étape. Ce procédé permet de lever toute ambiguité quant aux indications fournies par le détecteur. Le dispositif comprend un détecteur (4), un amplificateur (5) du signal émis par le détecteur, un circuit d'abaissement de tension (1) asservi par l'intermédiaire d'un discriminateur (6) au signe et/ou à l'élongation du signal délivré par l'amplificateur.

Abstract: ABSTRACT OF THE INVENTION     Process of preparing vesiculated polyester granules A process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter.    The formation of aggregates of granules in the large scale production of granules using a metal oxide, hydroxide or weak acid salt as base can be overcome by using a surfactant which comprises a species   where a = 5-12, X is an anion of pK1 less than 2 and R is an alkylene oxide chain composed of units selected from ethylene, propylene and butylene oxides.  When alkylene oxide other than ethylene oxide is present in the chain, such alkylene oxide must not provide more than two units per chain and the chain must additionally comprise at least three ethylene oxide units.    The granules prepared by the process are useful as matting and opacifying agents in, for example, coating compositions.

Abstract: ABSTRACT      Apparatus for providing a sequence detected signal indicating that a synchronization sequence occurring at regular intervals in a stream of data has occurred or should have occurred.  The apparatus includes logic for detecting the synchronization sequence, logic responsive to the detec-tion logic for producing the sequence detected signal when the detection logic detects the sequence, and logic for producing the sequence detected signal at a fixed time after the synchronization sequence should have occurred.  If the synchronization sequence did occur, the apparatus thus produces two sequence detected signals; however, the device receiving the sequence detected signal responds to the first sequence detected signal and ignores the second.  If the synchronization sequence did not occur, the device receiving the sequence detected signal responds to the sequence detec-ted signal produced by the logic responsive to the timing apparatus.  The apparatus thus guarantees that the device receiving the sequence detected signal will always receive such a signal.
