摘要:
A filter including a porous support defining one or more channels therethrough, and a porous ceramic membrane layer on a surface of the porous support defining at least one of the one or more channels. The ceramic membrane layer includes an inorganic ceramic composition having the formula SiM p xp C y N z O m H n , where each M p present is independently selected from a p-block element or a d-block element; p is an integer from 1 to 5; for each M p present, xp is independently from about 0 to about 60; y is from about 0 to about 60; z is from about 0 to about 60; m is from about 0 to about 40; and n is zero or nonzero. At least one of y and z is nonzero when p is zero, and p is nonzero when y and z are both zero.

The invention relates to a filter unit for purification of impure water, which could be seawater intended for ballast water, pool water, waste water or the like. The purification is performed by means of filter modules comprising filter means with dead end filter elements of a sintered material, and the filter unit facilitates alternating backwashing of the filter means at the same time as the filter unit may perform filtration of the impure water. The invention likewise relates to use of a dead end filter element in a de-gassing version, the filter element comprising a top end, a bottom end and a plurality of substantially parallel arranged channels with blockings in different ends.

摘要:
The present invention relates to a light weight and permeable construction material and a process for the manufacture thereof by mixing cement, rubber aggregate, silicate based aggregated (gravely) and water. When cured, the rubber and silicate aggregates are bonded together in a porous and permeable matrix by the cementitious material. In addition, it is preferred that polymer fibres and/or rubber powder derived from waste rubber tyres is added to material and acts as an elastic binding material which improves the physical properties of the constructional material. Depending on the particular engineering application, material can be cast-in-place or formed into precast blocks.

Die Erfindung betrifft ein Verfahren zum Herstellen einer Vorrichtung, mit der sich ein kreiselndes Gasbett zum Tragen eines Körpers, vorzugsweise eines Glaskörpers erzeugen lässt mit den folgenden Verfahrensschritten: es wird ein Tragkörper hergestellt, der mehrere zueinander im wesentlichen parallele Kanäle aufweist, die an einer dem Glaskörper zuzuwendenden Tragfläche des Tragkörpers austreten; der Tragkörper wird um eine Achse verdrillt; die Verdrillung wird fixiert.
摘要:
Unusually strong and highly perforated plates are formed by pressurized filtration of a suspension of chopped ceramic fibers in an aqueous dispersion of colloidal alumina or colloidal silica through a mold (10) having a perforated filter base (20) and a pin support base (12) having pins (14) that extend through and beyond the perforations (25) of the filter base (20). Pressurized filtration is preferably conducted by applying vacuum on the downstream side of the mold. When the resulting compact layer of chopped fibers (24) deposited on the perforated filter base (20) has the desired thickness, filtration is stopped. The perforated filter base (20) and pin support base (12) are moved apart to retract the pins (14) from contact with the perforated compact layer of chopped fibers (24) which is transferred to a drier. By operating the drier at a temperature not exceeding about 650 DEG F (343 DEG C), the compact layer of chopped fibers (24) is converted into a novel unsintered, perforated plate of unusual strength.
摘要:
This invention provides a functional material-containing ceramic filter and a method of manufacturing the same. This invention also provides a ceramic filter the average particle diameter of which is the smallest at the surface with which a liquid to be purified is brought into contact and gradually increases continuously inward, and which is manufactured at a low material cost. A functional material-containing ceramic filter. A porous ceramic filter wherein the average diameter of fine particles constituting the filter increases continuously from at least one surface thereof inward. A material compound which contains a functional material as necessary is molded into a ceramic filter. The molding is done with ultrasonic vibration or with ultrasonic vibration and compaction applied to at least one surface of the molded piece. In manufacturing this ceramic filter, the extrusion molding die is provided on at least a portion thereof with an ultrasonic vibrator or with an ultrasonic vibrator and a compaction means.

A process and a porous body (30, 31, 32, 33, 34, 35, 36, 40, 140, 214, 322, 410, 516, 620, 622, 624) for refining molten glass. The porous body has an inlet (42, 216), an outlet (44, 218), and a plurality of pores (46, 46', 146) through which molten glass can flow between the inlet and the outlet. The plurality of pores are defined by walls (48, 150) having wall surfaces (50, 148) that are configured to interact with the molten glass as the molten glass flows between the inlet and the outlet to help refine the molten glass.
