Patent EP-0417572-B1 (EP)
Inventor: SABEL BERNHARD A DR
IPC: A61K9/28
Filed: 1990-08-31
Granted: 1996-08-07
Abstract: A polymeric device releasing biologically active, water-soluble materials having a molecular weight of less than 1000 in a controlled, continuous and linear manner over an extended period of time. Insoluble polymer matrixes can be defined in any shape, size and drug content. When applied to medical use, biocompatible polymers are used so that the device is implantable. The device is made by modifying prior art devices based on diffusion of fluid into a polymeric matrix containing dispersed biologically active molecules to yield a polymer device which can be placed in a fluid environment, so that fluid is absorbed by the device and the water soluble molecules diffuse into the fluid environment, leaving behind pores and channels, where the rate of diffusion is limited by an impermeable coating over a portion of the polymeric matrix and/or by adjusting the drug loading to produce the number and size of pores and channels to the surface of the polymeric matrix yielding the desired release rate of the biologically active molecules. The device is characterized by several distinguishing features: a mechanism usually associated with macromolecular release which is applicable to small, water soluble molecules and controlled, long term linear release of large drug quantities.

Title: Closures for containers
IPC: B65D41/34
Filed: 1990-07-12
Granted: 1993-03-24
Abstract: A container closure moulded from plastics material has a top 10, an internally screw-threaded skirt 11, and a tamper-evident ring 13 connected to the bottom edge of the skirt by frangible bridges 15. The radially inner surface of the ring 13 is formed with an odd number of evenly spaced inwardly projecting protrusions 16 for engaging under a security band on the neck of a container. The use of an odd number of protrusions ensures that no two protrusions are diametrically opposite each other and in consequence permits the closure to shift or wriggle diametrally during application of the closure to a container and thus facilitates movement of the ring 13 past the security band. An annular groove 20 is formed on the radially-outer surface of the ring at a location axially between the upper ends of the protrusions 16 and the bridges 15, and serves to form an annular hinge about which the lower parts of the ring 13 can pivot during application of the closure.

Abstract: Le générateur de signaux d'horloge décrit comprend un oscillateur à quartz (1), qui génère des signaux d'horloge traversant un filtre passe-bande (2) de façon à former des signaux d'horloge de référence sinusoïdaux. Les signaux d'horloge sont acheminés dans un multiplicateur (3) et sont retardés d'un quart de période par une unité de retard d'un quart de période (4), de façon à former des signaux d'horloge d'une valeur égale à cos 2πfct, qui sont ensuite appliqués à un multiplicateur (5). Lorsqu'un signal de synchronisation horizontal est introduit depuis une unité externe, un convertisseur A/N (6) échantillonne le signal d'horloge de référence avec le signal de synchronisation horizontal et envoie un signal numérique vers une unité d'exploitation (7), qui exploite une différence de phase entre une phase absolue du signal numérique et une phase prédéterminée et qui produit une composante d'onde sinusoïdale sin (a-b) et une composante d'onde de cosinus cos (a-b), qui correspondent à cette différence de phase. Le multiplicateur multiplie le signal d'horloge de référence sin 2πfct par la composante d'onde sinusoïdale sin (a-b), et le multiplicateur (5) multiplie le signal d'horloge de cosinus cos 2πfct par la composante d'onde de cosinus cos (a-b). Les résultats multipliés sont ajoutés les uns aux autres dans un additionneur (9) et la somme obtenue est convertie en une valeur binaire au moyen d'un comparateur (12), lequel produit ensuite une impulsion d'horloge de sortie W.CK.

Abstract: The invention relates to a method and a device for forming machine currents (iw, ip, im) in a converter-fed rotating field machine (10) as a function of a measured intermediate-circuit current (id). According to the invention, the measured intermediate-circuit current (id) is integrated over times during which either any desired or a specific active voltager vector (u1,...u6) is set by means of a combination of switched-on converter valves (T1,...,T6) of the pulse-controlled invertor (8). In this way, the active current (iw) and two currents (ip, im) of the rotating field machine (10) can be simulated, the positive current (ip) being formed from positive phase currents (iR, iY, iB) and the negative current (im) from negative phase currents (-iB, -iR, -iY), and it being possible to form these currents from the knowledge of the angle ( gamma ) of the rotating voltage space vector (u*) into continuous phase currents (iR, iY, iB). <IMAGE>
