Patent EP-0258827-A1 (EP)
Inventor: LARSEN CHRISTIAN
IPC: F16L47/02
Filed: 1987-08-27
Abstract: By a method for connecting a plastic pipe end (4 and 4ʹ, respectively) to a plastic welding sleeve (1) a heater (3) of annealed expanded metal is initially mounted on the pipe end (4 and 4ʹ, re­spectively), whereafter the welding sleeve (1) is pushed over said pipe end. Subsequently the plastic welding sleeve (1) is pressed downwards to abut the heater (3) in question by means of a known clamping device and heat supplied from the outside. The heater (3) is then connected to a welding generator and a microprocessor measuring and controlling the current through the heater and the voltage across the heater (3) during the entire heating phase. During the first phase of the heating process the heater (3) is supplied with a constant current, and when the microprocessor registers that the increase in voltage per time unit has dropped below a prede­termined level corresponding to a specific temper­ature, said microprocessor computes the ohmic re­sistance of the heater corresponding to a desired predetermined final welding temperature. This final welding temperature is kept constant for a period thereafter. 
     In this manner a method is provided for connecting a plastic pipe end to a plastic welding sleeve by means of an extensible heater. During the fully automatized welding operation this heater is situat­ed in the welding area, whereby a uniform distri­  bution of heat is ensured and results in a welding of high strength and quality.

Abstract: On forme un multiprocesseur principal-asservi (Fig. 1) en reliant un processeur asservi (25) à un connecteur d'entrée/sortie d'un monoprocesseur et en modifiant au minimum le système d'exploitation du monoprocesseur. Lors de l'initialisation, un premier sous-programme (Fig. 5) réoriente les vecteurs d'interruption asservie (200) qui pointent sur un sous-programme commun de gestion d'interruption (Fig. 11). Avant qu'une opération soit exécutée sur un processeur asservi, un deuxième sous-programme (Fig. 9) alterne les bornes (217, 218) des piles d'exécution de l'opération. Un appel du système d'exploitation sans interruption durant l'exécution de l'opération déclenche un contrôle par microprogramme automatique (Fig. 3) du pointeur de pile d'exécution (203) par rapport aux bornes de pile. La survenance d'une interruption ou la présence d'une exception de pile provoque la suspension de l'exécution de l'opération et le recours au sous-programme de gestion d'interruption ou à un sous-programme asservi de gestion d'exception de pile (Fig. 10), respectivement. Chaque sous-programme de gestion fait appel à un sous-programme de supression asservi (Fig. 14) pour rétablir les bornes de pile de l'opération, de façon à valider les valeurs et à transférer l'opération en vue de son exécution vers le processeur principal (12). Dans le processeur principal, l'exécution de l'opération recommence à partir du point où sa suspension a eu lieu et les opérations qu'on demande au système d'exploitaition par l'intermédiaire de l'appel ou de l'interruption sont exécutées.

Abstract: On prévoit, pour un récipient à sortie cylindrique (2), un système de fermeture (10) déformable réalisé en une seule pièce, sous forme d'un capuchon comportant une paroi d'extrémité circulaire (12) dotée d'une bordure périphérique (14) permettant sa fixation sur la sortie (2). La paroi d'extrémité (12) comporte une ligne à entaille (56) qui définit un segment traversant une partie de la paroi d'extrémité (12). Un joint creux complexe (32), positionné et dimensionné pour insertion dans la sortie du récipient (2), dépend de la surface intérieure de la paroi d'extrémité (12). Le joint comporte également une lèvre externe conique (34) pour former un joint partiellement détachable co-opérant avec la surface interne (6) de la sortie du récipient (2). Un orifice de distribution (22) traverse la paroi d'extrémité (12). Lorsqu'une pression interne est exercée sur la surface externe de la paroi d'extrémité (12), une partie de la paroi d'extrémité à l'intérieur de la ligne à entaille (56) est déplacée vers l'intérieur avec une partie du joint (32) et de la lèvre conique (34) qui est repérée avec celui-ci. De cette manière, la partie déplacée de la lèvre conique (34) est dégagée de sa position d'étanchéité par rapport à la surface interne (6) de la sortie du récipient (2), alors que la partie du joint (32) et la lèvre conique (34) qui sont à l'extérieur de la ligne à entaille (56) restent dans une position d'étanchéité par rapport à la sortie (2). Une fois que la pression n'est plus exercée sur la paroi d'extrémité (12), la partie de la paroi d'extrémité (12) qui a été déplacée vers l'intérieur ainsi que le joint (32) se déplacent vers l'extérieur, et ramènent la partie déplacée de la lèvre conique (34) à sa position normale d'étanchéité avec la sortie (2). On décrit également une forme modifiée du système de fermeture (10) qui peut se verrouiller et résiste aux manipulations par les enfants.

Abstract: Les servodirections hydrauliques à crémaillère connues, comportant un vérin hydraulique agencé parallèlement à la crémaillère, présentent deux carters mutuellement séparés et exigent donc un encombrement important. Le nouvel agencement prévoit de disposer les éléments se trouvant en relation d'entraînement, dans un carter monobloc et à des intervalles exacts les uns des autres, et de les loger sous le plus faible encombrement possible. Le pignon d'attaque (5) est monté, avec possibilité de rotation limitée, sur la colonne de direction (4) afin de donner du jeu dans la commande. L'encombrement en sens axial de ladite colonne de direction s'en trouve ainsi réduit. Le piston moteur (2) s'engrène directement dans le pignon d'attaque (5) au moyen d'une denture et de telle manière que les plans d'engrènement de la crémaillère (1) et du piston moteur (2) soient en regard l'un de l'autre. On peut ainsi gagner de la hauteur au montage.

Abstract: Electrical tool for the mixing of at least two substances. The mixer is driven by a spindle gear wheel which is provided with a hollow hub and with claws on its endface towards the mixer, which claws interact with recesses made in the mixer, allowing the mixer to be set in rotation. A shaft journal (66), provided with a longitudinal tooth gearing (67), is connected in a rotationally fixed manner to the hollow hub (36) of the spindle gear wheel (33) and has arranged longitudinally displaceably on it a coupling element (68), which has a corresponding longitudinal tooth gearing (67') and contains spring-mounted coupling pins (69). The coupling pins correspond with the recesses (37) in the mixer (26) and the longitudinal displacement of the coupling element (68) is performed by means of a sliding member (73), which on the one hand acts on the coupling element and on the other hand can be operated by the cover (32) in such a way that, when the cover is swung up, it interrupts the frictional connection between mixer (26) and coupling element (68) and automatically re-establishes the said connection when the cover is closed. <IMAGE>

Abstract: There is described a new inclusion complex of nicardipine or its hydrochloride with beta-cyclodextrin, which is prepared by admixing nicardipine or its hydrochloride with beta-­cyclodextrin in a molar ratio of the compounds 1:0.9-1.1 under stirring at a temperature from about room temperature to the boiling temprature of the reaction mixture in an aqueous or ethanolic medium, cooling the reaction mixture to 0 ° to 5 °C and isolating the desired complex. 
     The inclusion complex of nicardipine or its hydrochloride pos­sesses cerebrovascular-vasodilatory and coronary-vasodilatory properties, which are equally well expressed as those of nicar­dipine or its hydrochloride themselves, yet owing to the better solubility of the complex at a higher pH range, such as it ex­ists e.g. in the intestinal tract, the manufacture of sustained release pharmaceutical forms is made possible, whereby a greater extent of dissolution of the active substance is provided also in the intestinal juice.

Abstract: A process is described for the permseparation of gases, iso­topes, and liquids by permselective membranes which comprise the use of membranes of solid materials with pores having a size, shape and length resulting in a microcapillary action which causes micro­phase separation on the molecular level of one component of the fluid, i.e. the component with the highest throughput, and the transport of that component across the membrane by flowing through the pores resulting in a complete or substantially complete separa­tion; said permseparation depends on the difference between the bulk properties of the components. The observations leading to the present invention such as large separation factors between hydrogen and helium, and hydrogen and air, and permseparation of butanol and water as well as special and general procedures of how to carry out the present invention which relates to all areas of science and technology concerning the separation by membranes are described. This also include improved methods of producing nuclepore micro­filters.

Abstract: The present invention relates to novel continuous human adenocarcinoma cell lines of epithe­lial lung tissue origin that produce fully processed or semi-processed surfactant-associated proteins, e.g., SAP-35 and SPL(Phe). The surfactant-associated proteins confer biological activity to pulmonary surfactant phospholipids and are useful for formu­lating pulmonary surfactant replacement for,  inter alia , diagnosis and therapy of human diseases asso­ciated with surfactant deficiency. Exemplary cell lines of the present invention designated as NCI-H441-4, NCI-H820, NCI-H322 and NCI-H1404 are deposited with the American Type Culture Collection (ATCC) of Rockville, Maryland under accession Nos. CRL 9400, CRL 9531, CRL 9532 and CRL 9533, respectively. The present invention also relates to a novel method for regulating the expression of a surfactant-asso­ciated protein by cells having the ability to express at least one surfactant-associated protein and/or mRNA encoding therefore by exposing the cells to a regulating agent, such as a glucocorticoid hormone, 8-Br-cAMP or a functional equivalent, to selectively induce or inhibit the expression of a surfactant-associated protein. The present invention   is also directed to novel methods to screen for tumor cells of pulmonary epithelial origin which produce surfactant-associated proteins and purifying the proteins from lysates of the cells or the media. The present invention also relates to novel human proteins, Mr=40-46,000, Mr=27-33,000 and Mr=23,000 on SDS-PAGE, which are believed to be precursors of the SPL(Phe) human protein. The SPL(Phe) mRNA initially translates an Mr=40-42,000 preproprotein which is glycosylated at asparagine residues and sialylated resulting in an Mr=40-46,000 SPL(Phe) proprotein. The Mr=27-33,000 protein is a proteolytically cleaved fragment of the Mr=40-46,000 precursor, and the Mr=23,000 protein results from de-glycosylating and de-sialylating the Mr=27-33,000 protein.

Abstract: The device has a coupling pin (3) at the end of the drinking hose (2). A diaphragm part is retained in the coupling pin, the sealing effect of which diaphragm part can be cancelled by central pressure (A) from outside. The diaphragm part, however, also opens in the event of an overpressure exerted from inside, so that the drinking hose can be blown out after the drinking process has ended. The coupling pin (3) can be pressed into a connecting piece which is sealed with the aid of a valve lifter (10). In the pressed-in state, the valve lifter opens the diaphragm part, the valve lifter itself being pushed into the open position. <IMAGE>
