Patent JO-1882-B1 (JO)
Title: A gypsum cellvlosic fiber acoustical tile composition
Inventor: BAIG MIRZA A
IPC: C04B26/28
Filed: 1995-08-08
Granted: 1996-07-25
Abstract: An acoustical tile composition based on a gypsum/cellulosic fiber composition which can replace all or a portion of the mineral wool normally present in acoustical ceiling tiles. The gypsum/cellulosic fiber composition is combined with a lightweight aggregate material and a binder to form composition which is used in a water-felting process to manufacture acoustical ceiling tiles and panels. The preferred source of the cellulosic fiber is a composite gypsum/cellulose fiber material which is prepared by mixing the gypsum and cellulosic fiber material with sufficient water to form a dilute slurry which is then heated under pressure to calcine the gypsum, converting it to an alpha calcium sulfate hemihydrate. The resulting composite material comprises cellulosic fibers physically interlocked with calcium sulfate crystals. Another source of both gypsum and cellulosic fibers is waste (scrap) gypsum wallboard. Expanded perlite is the preferred lightweight aggregate material.

Filed: 1986-05-13
Granted: 1988-03-20
Abstract: Flexible magnetic recording discs are usually contained in a sleeve, which has two apertures, one for the drive mechanism and one for the magnetic head.  The drive mechanism usually clamps onto the hole in the centre of the disc and relies on friction and centrifugal force to hold the disc in the right position as it rotates at high speed. This is not a satisfactory arrangement for very small diameter discs, and an alternative drive system is available.  The disc is clamped at its centre to a boss which is free to rotate inside the protective sleeve.

Title: Protein purification
Inventor: LAI POR-HSIUNG
IPC: C12N15/09
Filed: 1986-10-04
Granted: 1993-05-08
Abstract: Chromatographic procedures are individually and jointly applied to the rapid and efficient isolation of biologically active proteins and especially glycoproteins such as recombinant erythropoietin present in the medium of growth of genetically transformed mammalian host cells. Illustratively, recombinant EPO is isolated from culture fluids by reverse phase chromatography employing a C4 or C6 column and elution with ethanol. Recombinant erythropoientin may also be purified by anion exchange chromatography employing, e.g., a DEAE resin, with preliminary selective elution of contaminant materials having a lower pKa than erythropoietin from the resin under conditions mitigating against acid activated protease degradation. Practiced serially, the two chromatographic procedures allow for high yields of biologically active recombinant erythropoietin from mammalian cell culture media.
