IPC: B01J8/38
Filed: 1987-05-05
Abstract: 1. Method for carrying out endothermal processes on fine-grained solids in a circulating fluidised bed formed by a fluidised bed reactor, separator and recycling line, which bed is preceded by a multi-stage pre-heater which is operated with waste gas from the circulating fluidised bed, and succeeded by a multi-stage fluidising cooler, in which a) oxygen-containing gas is supplied to the fluidised bed reactor of the circulating fluidised bed as a fluidising gas and on a higher entrance level as a secondary gas, and fuel is supplied between the entrance levels for the oxygen-containing gas, b) the oxygen-containing secondary gas is previously pre-heated by direct heat exchange in the succeeding fluidising cooler, and c) the oxygen-containing fluidising gas is previously pre-heated by indirect heat exchange in the succeeding fluidising cooler, characterised in that at least a substantial part of the solids is pre-heated by indirect heat exchange in a pre-heating stage, which is first in the direction of flow of the solids, the heat transfer medium required for this purpose is heated up in the second stage of the fluidising cooler and after passing through the pre-heating stage is recycled to the second stage of the fluidising cooler, and the required oxygen-containing fluidising gas is heated up only in the first stage of the fluidising cooler.

Abstract: An electric motor driven inline hydraulic apparatus comprises a common housing (10), a stationary shaft (11) mounted in said housing (10) and spaced pump cylinder block subassemblies (12) that rotate around and are mounted on said shaft (11). Each subassembly (12) includes a cylinder block and a plurality of circumferentially spaced pistons (13). The cylinder block subassemblies (12) are positioned such that the pistons (13) of one subassembly extend toward the other subassembly. A common yoke plate (14) is mounted between the two cylinder blocks (12) and bears the two groups of piston shoes, one on each of its two bearing surfaces. Each cylinder block is driven independent of and in direction opposite to the other by an electric motor (16, 18) integrally mounted such that its hollow rotor (16) houses the block (12) and drives it. All components described above are contained in one housing (10) and operate submerged in hydraulic fluid.

Abstract: A decal support sheet comprises a paper base (1) having a porous surface (2), and a plastic film (3) is atop this surface. No release layer is interposed between the paper sheet base (1) and the plastic film (3) which is applied to the paper base (1) so that it adheres well to the porous surface of the paper and adopts its texture but does not penetrate it. The decal image (9) is applied to the plastic film (3). When the decal is soaked in water the adhesion between the paper base (1) and plastic film (3) is substantially released but they can withstand substantial horizontal forces without separating.

Inventor: GUZIK NAHUM E
IPC: H02P7/00
Filed: 1987-07-30
Abstract: A current driver circuit for an inductive load, such as a motor winding, provides unidirectional, controlled current through the winding by use of two pulse width modulator switches on opposite sides of the winding or bidirectional current control by use of two pairs of pulse width modulated switches; each pair straddling the winding relative to the power supply. Each pair of switches is modulated in two different modes to control current during two different operating conditions. The first mode of modulation is used for all but rapidly decaying winding current conditions and a second mode provides control for rapidly decaying winding current. In the first mode, unidirectional current to the winding from the power supply is pulse width modulated while the companion switch of the pair is on. In the second mode of operation for rapidly decaying current control, current from the power supply to the winding is shut off by one switch while the companion switch is pulse width modulated to cyclically switch winding, circulating current back through the power supply in the reverse direction to allow rapid decay of the circulating current. In this manner, increased efficiency is obtained while reducing electromagnetic interference.

Abstract: Le procédé de transmission de données numériques par messages organisés en trame selon l'invention est essentiellement un procédé adaptatif dans lequel : 
    - lors de l'émission par un poste origine, les trames comportent un en-tête constitué d'une chaîne pseudo-aléatoire de 32 bits, un champ numéro de trame (ou nature de la commande) et un champ de données surcodées par une chaîne pseudo-aléatoire de 7 bits. Les trames sont répétées, puis entrelacées, le taux de répétition étant adapté au type de données transmises dans les trames pour former les messages à émettre ; 
    - lors de la réception par un poste destinataire, l'acceptation d'une trame reçue est réalisée après décodage et correction d'erreurs par décision au moyen d'un circuit de décision 14 fonctionnant par vote majoritaire sur les trames répétées lors de l'émission, et un message d'acquittement est généré de la même manière en retour ; 
    - les trames d'acquittement reçues par le poste origine per­mettent de sélectionner les trames non acceptées qui sont alors retrans­mises sélectivement par le poste origine. 
     L'invention s'applique notamment aux réseaux de transmission dans lesquels les qualités de liaison sont variables, de manière à optimiser à chaque instant le débit de transmission en fonction de la qualité de la transmission.

Abstract: Le radar adaptatif (10) permet de réduire sensiblement les échos parasites de fond, en particulier les échos parasites relativement constants dans le temps, tels que le retour de mer, et spécialement à de faibles angles d'effleurement du radar. L'appareil de radar (10) comprend une antenne de transmission (12) ayant des éléments de transmission (26, 28) orientés horizontalement et verticalement et une commande de phase relative entre les deux, et une antenne de réception (14) ayant également des éléments de réception (30, 32) orientés horizontalement et verticalement avec aussi une détection de phase relative et déphasage entre les deux. Un générateur de signaux radar (16) pouvant être commandé envoie des signaux à l'antenne de transmission (12) et un processeur de signaux (18) pouvant être commandé traite les signaux de retour provenant de l'antenne de réception (14). Des moyens (20) sont prévus pour déterminer, à partir des signaux test de retour, une polarisation nulle moyenne de fond pour plusieurs cellules azimuthales et de portée du radar ainsi que pour fournir des signaux de commande de polarisation nulle Ho, Vo et oo, au générateur de signaux (16) et au processeur de signaux de retour (18) pour faire fonctionner le radar à un état de polarisation qui est le même que la polarisation nulle moyenne des échos parasites.

Abstract: Un appareil permettant d'obtenir un seul balayage des données d'images à résonance magnétique nucléaire concernant une pluralité de plans sélectionnés d'un objet, inclinés avec différents angles, utilise un indicateur de tranche (31 de la Fig. 7) pour transmettre un signal indicateur d'un plan particulier à une mémoire à accès sélectif (28 de la Fig. 7) conservant des paramètres de multiplication et de décalage et fournissant des termes de multiplication et de décalage correspondant à l'angle du plan en question. Un générateur (20 de la Fig. 7) fournit une forme d'onde à gradient générique à une unité arithmétique (25 de la Fig. 7) qui combine cette forme d'onde avec les paramètres de multiplication et de décalage conservés par la mémoire à accès sélectif afin de créer des formes d'ondes qui, lorsqu'elles sont appliquées aux bobines de gradient (53, 57 et 60 de la Fig. 7) d'un appareil de résonance magnétique nucléaire, mettent en rotation le sélecteur de tranches et les gradients de lecture, ce qui permet d'obtenir des données d'images sur des plans inclinés avec différents angles.
