Abstract: Une soupape de frein à deux circuits (10) est munie d'un mécanisme de régulation du différentiel de décharge qui permet de réguler le différentiel entre les pressions de décharge du premier (70) et du second (114) circuit de freinage. Le mécanisme de régulation du différentiel de décharge (116) comprend un arrêtoir de ressort (122) qui est monté sur l'extrémité de la tige (86) de la soupape de relais et qui est destiné à recevoir un piston (130) sollicité par ressort. Le piston est en prise avec l'élément actuateur durant l'actionnement des freins, de façon à transférer la force du ressort (132) sur l'élément de relais et par conséquent, sur les éléments de soupape du second circuit. Ce transfert de la force du ressort permet de réduire la pression de "fissuration" des éléments de soupape commandant la communication à travers le second circuit, réduisant ainsi le différentiel entre les pressions produites par le premier et le second circuit.

Abstract: A robot control apparatus stores the result of operation on the inertia term of an equation of motion depending upon the position of the robot arm, so that the operation on the inertia term is set longer than the operation period on the drive torque. In controlling the robot with the same precision, therefore, the drive torque can be calculated in a short period of operation time.

Abstract: Méthodes pour cibler la libération d'un agent pharmacologique actif chez un animal en administrant cet agent encapsulé dans des microsphères protéinoïdes qui sont résistantes à l'environnement rencontré depuis leur point d'introduction jusqu'à leur migration vers les organes, fluides ou cellules du corps ciblés, où elles sont instables. Des systèmes, administrés par voie orale, pour la distribution d'insuline, d'héparine et de physostigmine font appel à des microsphères d'encapsulage d'un diamètre inférieur à 10 microns environ pour la majeure partie d'entre elles, qui passent aisément à travers la paroi de l'estomac et sont constituées d'un proténoïde acide qui est stable et n'est pas affecté par les enzymes et l'acide de l'estomac, mais qui libère sous une forme pharmacologiquement active l'agent microencapsulé dans le courant sanguin pratiquement neutre. Des microsphères protéinoïdes basiques encapsulant un système vecteur d'oxydoréduction à la dopamine sont administrées dans le tube digestif inférieur où elles sont stables, puis pénètrent dans le courant sanguin où l'agent encapsulé est libéré de façon semblable.

Patent EP-0317030-A1 (EP)
Inventor: PRINS GEERT JAN
IPC: B65H29/46
Filed: 1988-11-17
Abstract: The invention relates to a device for stacking flat articles, such as postal items. First guide means (9), which form part of a stacker head (7) and which bound a stack of articles (2) already stacked in a stacker bed (1) in a plane of stacking (D), carry out an imposed to-­and-fro pulse movement between a rest position (A) and an outermost position (C) transversely to a supply line (3) and in line and level with the stack to make stack space for a short time for an article 2.2 to be stacked, which article is entering at that moment via the supply line (3). The pulse movement can be realized by hanging the first guide means (9) on the one hand by means of a first set of parallel leaf springs (17, 18) to a frame part (19, 20, 31, 32) in such a way that they can swing, and on the other hand by coupling them to the driving end (28) of drive means (25, 26) carried on bearings in the frame part. In the rest position (A) the stack pressure exerted in the plane of stacking (D) on the first guide means (9) of the stacker head (7) will (practically) completely be exerted as a sideways push­ing force on the frame part. This fact can be utilized with advantage for a very accurate stack-force measure­ment. For that purpose the frame part is connected, on the one hand, via a second set of parallel leaf springs (33, 34) to the fixed world (35, 36, 4) and, on the other hand, via a coupling bar (37) to a force transdu­cer (38, 39). A very small sideways displacement of the frame part under the sideways pushing force caused by the stack pressure is registered by the force transducer (39) and converted into a signal which can be used for a change of position, if any, of a stack support (8) for regulating the stack pressure.

Abstract: Wellbores are cemented with a cement composition formed from drilling fluid occupying the wellbore by circulating a quantity of drilling fluid mixed with a cement material and a dispersant such as a sulfonated styrene copolymer with or without an organic acid into the wellbore to displace the drilling fluid and to continuously convert the drilling fluid into the cement composition. The cement composition may be recirculated through the space in the wellbore to completely evacuate any drilling fluid not converted to cement so as to minimize any faults in the cement composition occupying the wellbore. A preflush composi­tion containing the dispersant and being rheologoically compati­ble with both the drilling fluid and the drilling fluid converted to cement slurry may be used as a displacement fluid.
