Patent EP-0077598-A1 (EP)
Inventor: EASTMAN JAMES MIDDLETON
IPC: F15B13/04
Filed: 1980-03-18
Abstract: An electrohydraulic doser actuator of the kind comprising a step piston the axial position of which is variable as a function of metered doses of pressurized fluid which are vented to or from a control chamber by a first on-off valve connecting the latter to a high pressure source or a second on-off valve connecting it to a low pressure source, said valves being normally closed and thus establishing a hydraulic lock on the piston to maintain same in its last reached axial position. 
     In order to improve the precision of positioning of the piston (58, 60), the invention provides for a pair of additional on-off valves (52, 53) mounted in parallel relationship to the main on-off valves (51, 54), respectively, and having a smaller opening than said main valves for the control of small adjustments of the position of the piston. 
     For use particularly in gas turbine control systems.

Abstract: A nylon/ethylene vinyl alcohol copolymer (EVOH) blend suitable for extrusion into strong, tough films possessing good oxygen barrier qualities comprises 90 to 20 weight percent of nylon and 10 to 80 weight percent of EVOH; the nylon is compounded with a plasticizing agent which typically lowers the normal extrusion temperature of the nylon (which is in the region of 266 to 282 DEG C) to a temperature of 204 to 249 DEG C; at this temperature the blend can be extruded by the method disclosed without significant degradation. 
<??>The blend exhibits enhanced adhesive qualities, as compared to films of EVOH copolymer per se, and is well adapted for use in multilayer films. A method for fabricating the resin blend into a composite film involves combining the blend with a chosen resin an an extruder and coextruding the blend and this resin. 
<??>Films made from the nylon/EVOH blend are suitable for the packaging of comestibles.

Abstract: A mechanical seal assembly having a rotatable sealing ring means (18) mounted for rotation on a shaft and a stationary sealing ring means (20) connected to a housing flange, the sealing ring means having opposed sealing surfaces (22, 24). The assembly also has means (42) urging the sealing surfaces toward one another. The rotatable sealing ring means (18) is of stepped configuration and constructed as an integral pair of equal axial length ring portions (A, B), one portion having its inner and outer diameters larger than the respective diameters of the other. Generally, the ring portion having the smallest inner and outer diameter is that ring portion having the sealing surface - one that opposes the sealing surface of the stationary sealing ring means. 
     The degree of deflection of the sealing surface because of hydraulic load or pressure can be selected by selecting the diameters of the pair of ring portions, i.e., if the ring portions have substantially the same shrinkage, the sealing surface will remain substantially flat; if the shrinkage of the ring portion with the largest inner and outer diameters is more than the other ring portion, the seal surface will become convex; if the opposite relationship of the cross-sections is selected, the seal surface will become concave.

Abstract: Dispositif de conversion d'un signal électrique ou quantité de format analogique (tel que la valeur d'un élément d'un circuit électrique) en un signal correspondant de format impulsionnel, de préférence sous la forme d'un train d'impulsions périodiques dont les longueurs peuvent être modifiées en tant que pourcentage de la période cyclique. Un signal pulsé de cycle de travail est développé dans une boucle de réaction négative autour d'un intégrateur (10) possédant un signal d'entrée de format analogique (Ein). La sortie de l'intégrateur commande le niveau du courant continue d'un signal à pente ascendant et descendant (18) qui est envoyé à un comparateur (26) pour produire des impulsions pendant les périodes où la tension du signal à pente est supérieure (ou inférieure) au niveau de déclenchement du comparateur (26). Ces impulsions commandent un commutateur (S1, S2) entre l'entrée de l'intégrateur et une tension de référence (EREF) de manière à produire un signal de réaction négative (Efb) pour l'intégrateur. Une action de réaction négative commande le niveau du courant continu à la sortie de l'intégrateur et fixe ainsi le cycle de travail de l'impulsion à une valeur telle que le niveau moyen des signaux envoyés par l'intermédiaire du commutateur pulsé à l'entrée de l'intégrateur a un rapport prédéterminé avec le signal d'entrée appliqué. Le signal du cycle de travail produit grâce à une telle action de réaction correpond à la valeur du signal d'entrée appliqué.

Abstract: The iron-cored yokes (1a or 1b) in such three-phase reactor coils are used to complete the magnetic circuits between limbs (2a, 2b, 2c) of the iron core whose axes are arranged at right angles on the corner points of a triangle. According to the invention, additional coils (11a, 12a, 13a or 11b, 12b, 13b) are provided for suppressing additional magnetic fluxes in the iron-cored yokes (1a or 1b), of which coils in each case one surrounds an iron-cored yoke (1a, 1b) between two adjacent iron-cored limbs (2a, 2b, 2c), and coils (11a, 12a, 13a or 11b, 12b, 13b) arranged in each case on the same iron- cored yoke (1a or 1b) are electrically connected in the triangle. As a result of the arrangement of the additional coils (11a, 12a, 13a or 11b, 12b, 13b) on the iron-cored yokes (1a or 1b), the incidence of vibration in the latter is prevented by a multiple of the mains frequency, so that three-phase reactor coils constructed according to the invention are characterised by low power losses and by low noise emissions. <IMAGE>
