Patent EP-0392713-A1 (EP)
Inventor: WRIGHT ALISTAIR LOUIS
IPC: F15C1/16
Filed: 1990-03-30
Abstract: A fluidic ventilation control system comprises a pair of vortex valves (3, 4) connected axial port to axial port in a passageway (7, 8) which can connect a main tunnel (1) with a service tunnel (2). The tangential ports of the vortex valves communicate with pressure gas supply (13), with valves (11, 12) to control the supply of pressure gas to the vortex valves. The valves (11, 12) are responsive to signals generated by sensors, such as pressure and heat detectors, in the tunnels to control the supply of pressure gas to thereby regulate the flow in the passageway in response to changes in conditions in the tunnels.

Abstract: The preparation of pharmaceutical powder compositions which are directly compressible into tablets, is disclosed. The disclosed process includes subjecting an aqueous slurry/solution of a pharmaceutically active drug specifically naproxen or naproxen sodium (which slurry may be directly obtained without drying from the synthesis of the drug), alone or in admixture with an aqueous mixture of excipient materials, to a controlled form of spray drying to produce a dry powder of uniform particle size wherein the drug is uniformly dispersed in and coated with the excipients. The powder can be readily combined with additional dry excipient materials and formed into tablets. The process provides for substantial savings in the manufacture of the tablets. The spray dried powder compositions are highly compressible. Utilizing such spray dried powder compositions, the tablets formed are readily dissolvable and also are stable under normal storage conditions and stress conditions of temperature and relative humidity.

Abstract: Un procédé de préparation d'un produit de dimère de lysozyme extrêmement purifié comprenant la dimérisation du monomère de lysozyme dans une solution tampon défine en pH 10, l'arrêt de la dimérisation à un point donné en abaissant le pH à 7 en ajoutant HCl ou une autre solution acide appropriée et la purification du lysozyme dimère au moyen d'une série de procédés d'élution effectués au moyen d'une chromatographie par colonne de résine à échange ionique. Le lysozyme monomère non dimérisé par le procédé de dimérisation initial est recyclé dans le processus afin d'augmenter la production. Ce système présente des avantages parce que de grandes quantités de dimère de lysozyme purifié peuvent être préparées avec efficacité et à des coûts raisonnables et le dimère de lysozyme ainsi produit est utile au traitement de maladies virales et/ou bactériennes sans provoquer les effets cytotoxiques associés au monomère de lysozyme.

Lors de l'application d'une force sur la courroie (1) de la ceinture, le corps extérieur (32) pousse le fluide (35) à travers des trous (36) jusqu'à un élément de répartition (8), qui est fixé au véhicule (34) au moyen d'une tige centrale et d'un écrou (33). L'élément de support (17) comprime un ressort (16) contre un élément pousseur (14), lorsque le corps extérieur est tiré vers le haut et, lors de la cessation de l'application de la force sur la courroie (1), le ressort (16) pousse l'élément de support (17), amenant ainsi le fluide à passer à travers le trou (37), dès lors que l'élément de contrôle de fluide (26) recouvre les trous (36), ce qui occasionne un retard avant que les dimensions d'origine soient atteintes, ainsi que la libération du crochet (2) lorsque l'élément pousseur (11) l'intercepte à nouveau. Est également prévu un dispositif enregistreur (18) qui est enfoncé par un élément percuteur (14), produisant ainsi une déformation qui indique l'utilisation effective de la ceinture de sécurité ainsi que la vitesse du véhicule.

Abstract: There is disclosed a method of manufacturing an epitaxial wafer which has the steps of: slicing a silicon single crystal pulled up to provide a wafer; etching the principal surface of the wafer to remove a damaged layer due to slicing of the surface; implementing specular processing to the principal surface of the wafer, allowing silicon to be subjected to vapor-phase epitaxial growth on the specularly processed principal surface; and implementing specular processing to the principal surface for a second time to remove various defects produced at the time of vapor-phase epitaxial growth, thus to improve flatness. By specularly processing the wafer surface after epitaxial growth, dust source and defect such as crown, etc. causing lowering of flatness, produced at the time of epitaxial growth, can be removed.

Abstract: The invention aims to automatically adapt the transmission level in each of the terminal stations (2) in a time-sharing communications network, a tree-like and fibre optic network, for example, so that the signals received in a central station (1) are at the same level whatever the various distances from the terminal stations to the central station. A reference word (MRA) is transmitted just after reception of the outgoing frame (T12) by an end station to be controlled and is compared with thresholds in the central station. Depending on the results of the comparisons, a transmission level modification order (U, D) is transmitted in the outgoing frame and detected by the said terminal station in which the transmission level is incremented or decremented as a result. <IMAGE>

Abstract: The invention concerns a device for metering of a coating agent onto a moving base, such as a paper or board web (W). The device (10) comprises a coating nip (N₁) formed by soft-faced applicator rolls (11,21), through which nip the web (W) is passed, the first applicator roll (11) from among said applicator rolls being journalled as fixed on the frame (1) of the device, and the second applicator roll (21) being linked to the frame (1) of the device pivotally by the intermediate of a loading arm (24) or equivalent. At least one of said applicator rolls (11,21) is in nip contact with a hard transfer roll (41,61), which is further in nip contact with a soft-faced metering roll (31,51). In a metering nip (N₂,N₄) between the metering roll and the transfer roll, a pond (P₁,P₂) has been formed out of the coating agent, out of which pond, as the rolls revolve, the coating agent is fitted to be transferred through the metering nip (N₂,N₄) onto the face of the transfer roll (41, 61) and from there further, through the transfer nip (N₃,N₅) formed by the transfer roll (41,61) and the applicator roll (11,21), onto the face of the applicator roll (11,21). From the applicator roll the coating agent is fitted to be transferred onto the web (W) in the coating nip (N₁). In the solution in accordance with the invention, the metering roll (31) and the transfer roll (41) placed next to the fixed applicator roll (11) and/or the metering roll (51) and the transfer roll (61) placed next to the mobile applicator roll (21) are linked pivotally to the same machine member on the frame (1) of the device.
