    Abstract: A process for the manufacture of porous sintered bodies with large open pore volume and defined pore diameter. A sinterable material in the form of finely ground powder is mixed with a leachable substance. The leachable substance is in the form of powder of a defined particle size. The mixture of sinterable material and leachable substance is heated to the sintering temperature and maintained there until the sinterable mass is sintered. The mass is then cooled and the leachable substance leached from the sintered mass.

    Abstract: This invention relates to advanced composite filtration media comprising a functional filtration component and a matrix component, and methods for preparing and using same. More particularly, this invention pertains to advanced composite filtration media and advanced composite filtration media products comprised of a functional filtration component, such as a biogenic silica product (e.g., diatomite), a natural glass product (e.g., expanded perlite), or a natural or synthetic crystalline mineral (e.g., titanium dioxide), which is thermally sintered to a matrix component, such as an engineering polymer (e.g., glasses, natural or synthetic crystalline minerals, thermoplastics, and metals) or a suitable natural material (e.g., rice hull ash, sponge spicules) that has a softening temperature below that of the functional filtration component. This invention also relates to advanced composite media and advanced composite media products, generally, which are also useful in non-filtration applications.

    Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum of plasma from the matrix.According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix.Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and equivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis.

    Abstract: Filter bodies are made by mixing borosilicate glass powder, potassium sulphate and 30% aqueous polyethylene glycol solution per kilogram of mixture. The mixture is filtered and dried and glass particles of a different size are mixed into the dried granulate. The resulting mixture is compressed at a pressure of 1000 bar to form blanks and sintered at about 860.degree. C. After cooling, the potassium sulphate is washed out of the blanks.
