摘要:
The invention relates to medicament excipient particles which are suitable for tissue-specific application of a medicament, especially to the central nervous system (CNS). The inventive particles can be loaded with or be free of the active substance. At least one detection protein is bonded to the particle surface or alternatively, the particle surface is modified in such a way that a detection protein bonds with it on contact.

Die Erfindung betrifft ein Verfahren zur Filtrierung und/oder Stabilisierung von Fluiden, insbesondere von Bier und eine Filterkerze zur Durchführung des Verfahrens mit einem rohrförmigen Filterkörper, der aus einem spiralförmig gewundenen Draht gebildet ist, wobei Spalte zwischen den Drahtwindungen als Fluiddurchlässe vorgesehen sind. Um eine Filterkerze bereitzustellen, die ermöglicht, Filterhilfsmittel und somit Filterkosten zu sparen, weist die Außenfläche einer Drahtwindung, die auf der Außenseite der Filterkerze liegt, eine Breite

Zur Reinigung von Regenwasser ist in einem Regenwasserbecken mindestens ein rohr- oder schlauchförmiges Sieb (1) angeordnet, durch welches das Regenwasser von aussen nach innen durchtreten und von Verunreinigungen befreit werden kann. Zur Reinigung des Siebes (1) dient ein Reinigungskopf (3), welcher mittels eines linearen Wasserstrahls (5) aus einer Düse (7) entlang des Siebes (1) bewegt wird. Geeignete Leitmittel im Reinigungskopf (3) setzen den Reinigungskopf (3) in Rotation und bewirken so eine einwandfreie Reinigung des Siebes (1) mit Wasser von innen nach aussen.
摘要:
A filtering device includes a container having an inlet for introducing liquid to be treated, an annular multi-layered prepacked screen assembly (7) provided in the container and having an outlet for treated liquid. The screen assembly includes three or more cylindrical screens (9,10,11) having different diameters and bieng coaxially disposed in the container with their axes extending vertically in the container. An anulus (12,13) is formed between the respective cylindrical screens (9,10,11). Two or more different filter materials performing different filtering functions are filled one in each of the annuluses between the cylindrical screens.

A water supply means to pump up the filtrate pumped up from a filtrate tank (13) into a filtrate discharge pipe (3), and a filtrate discharge pump (5) are provided, while an unthickened sludge extracting device (20) is fitted to the bottom of a sludge tank (1), where a high negative pressure acts upon the inside of filter plates (2) to conduct filtration, the unthickened sludge (10) is discharged from the unthickened sludge extracting device (20), and/or the unthickened sludge (10) present near the thickened sludge (11) is displaced by an unthickened sludge displacement means (22, 24, 28,29) so as not to contact the thickened sludge (11), and filtration of only thickened sludge (11) continues so that high-concentration thickened sludge (11) can be obtained without being affected by the water in the unthickened sludge (10).

摘要:
A method of testing the integrity of a filter element in a falter assembly includes a) wetting filter material of a filter element having an inlet side and an outlet side connected to an outlet conduit, b) subjecting the inlet side of the filter element to a gas pressure, c) measuring the pressure in the outlet conduit as a function of time, with a downstream outlet valve for the outlet conduit being closed, and d) determining whether the pressure measured at a preselected time exceeds a reference pressure by a predetermined amount, or determining whether the time required to reach a preselected pressure is shorter than a reference time by a predetermined amount.
摘要:
The filtration apparatus of the invention is of the type having one or more of upright tubular filter elements with the surface coated with a pre-coat layer of a filter aid through which a liquid is filtered. Different from conventional apparatuses, the filter element in the inventive apparatus is provided with a gas exhaust tube or liquid drain tube connected to the upper or lower part of the element. By virtue of this means, the liquid used for forming the pre-coat layer as the suspension medium can be completely discharged out of the apparatus prior to introduction of the liquid to be filtered so that the liquid in the apparatus can be switched from the pre-coat forming liquid to the filtered liquid without producing a mixture thereof causing no defects in the pre-coat layer.
