Inventor: CULVER KENNETH W
IPC: C12R1/92
Filed: 1991-12-10
Abstract: 2098510 9210564 PCTABS00013 This invention provides improved methods for producing high titers of recombinant viral vectors by culturing producer cells in a hollow fiber bioreactor. The titer of virus in the extra fiber space (EFS) of the hollow fiber bioreactor is sufficient to transduce target cells at a multiplicity of infection sufficient to render the transduced target cells useful for genetic therapy. In a preferred embodiment, target cells are transduced with the EFS  medium from a hollow fiber bioreactor in which a producer cell line, which releases packaged retroviral vectors into the EFS, has been cultured. Lymphocytes derived from an adenosine deaminase (ADA)-deficient individual that have been transduced with EFS medium that contains retroviral vectors that include RNA that encodes ADA, express ADA at a rate comparable to that of cells from an individual who does not have ADA deficiency.

Title: Aqueous developable photosensitive polyurethane-(meth)acrylate
Inventor: HUYNH-TRAN TRUC-CHI T
IPC: G03F7/00
Filed: 1993-07-12
Abstract: Abstract of the Disclosure A photopolymer useful in preparing water-developable, solid printing plates is prepared by preparing a urethane prepolymer by reacting   polyoxy-alkylene diols or polyester diols, or a mixture thereof, with an excess of diisocyanate, followed by chain extending the resulting prepolymer mixture with an alkyldialkanolamine, then reacting the chain-extended product with a hydroxyalkyl(meth)acrylate. The resulting photopolymer is suitably formulated with additional photoactive (meth)acrylate monomers or oligomers and photoinitiator for casting or extrusion on a substrate to form a flexographic printing plate. Following UV exposure of the plate through a negative, unexposed areas can be removed by washing with a slightly acidic aqueous medium, to give a plate with a desirable relief image.  The use of the aqueous washout solution as opposed to organic solvents minimizes pollution problems.

Inventor: BAKHAREV IOURI
IPC: B01D45/04
Filed: 1992-12-11
Abstract: A device for separating multiple-component fluids includes a truncated cone structure (2) having a conical main section (2a) defined by a plurality of coaxially aligned and axially spaced rings (3) of progessively diminishing inner diameters as viewed in the direction of movement (6) of the fluids being separated. The largest ring (3a) is located at that end of the conical main section at which the fluid is admitted thereto, and the smallest ring (3b) is located at that end of the conical main section at which separated solid particles are discharged. Each ring has an inside surface (13) which is convexly curved in a radial crosssection along the axis of the cone structure and faces in part counter to and in part across the direction of fluid flow. The inside surface of each ring meets the bottom surface (14) of that ring in a sharp edge (14a), with the tangent to the bottom surface at that juncture making an angle  alpha of at most 90 DEG  with respect to the direction of fluid flow, and with the tangent (T-2) to the inside surface at that juncture being substantially parallel to the axis of the cone structure. The arrangement of the rings causes the solid particles to be concentrated in the axial region of the cone structure for axial discharge therefrom while cleaned fluid exits from the cone structure through the gaps (16) between the rings.
