Title: Cell culture medium
Inventor: CORREA PAULO N
IPC: C12N5/0789
Filed: 1992-11-05
Granted: 1999-08-10
Abstract: A basal serum-free medium and a hematopoietic cell growth and differentiationpromoting serum-free medium based thereon are provided for the maintenance, cultivation, growth and differentiation of erythroid progenitor cells, other hematopoietic progenitor cells, and leukemia cells in which the effects of various growth factor compounds can be quantitatively evaluated. Both media are wholly serum-free and contain no intrinsic growth factor compounds. The hematopoietic growth and differentiation medium consists essentially of the basal serum-free medium to which has been added at least one primarily but not exclusively growth promoting agent selected from heme or hemin, interleukin-3 and recombinant human stem cell factor (and optimally all of them), and at least one primarily but not exclusively cell differentiation promoting agent selected from erythropoietin (Epo), insulin-like growth factor (IGF) and a retinoid (and optimally including all of them).

IPC: B65D75/36
Filed: 1995-05-02
Granted: 2000-09-26
Abstract: The blister pack comprises a base portion (B) and a cover layer (D). The base portion (B) comprises a hollow chamber (C) that contains a soft hydrophilic contact lens (L) and a sterile aqueous preserving solution (S), and a substantially flat flange (1) that extends right round the outside of the hollow chamber (C). The cover layer (D) is releasably sealed to the flange (1) in a sealing zone (2) that extends right round the circumference of the hollow chamber (C). The flange (1) comprises a grip region (3) that extends from one side of the hollow chamber (C) beyond the sealing zone (2) and is covered by a corresponding grip region (4) of the cover layer (D) but is not sealed thereto. The hollow chamber (C) comprises a dish-shaped main chamber and, adjoining the side of that main chamber, a secondary chamber in the shape of a channel tapering on all sides away from the main chamber, the main chamber making a smooth transition into the secondary chamber, and the main chamber and the secondary chamber together having a drop-shaped contour (14) in the plane of the flange (1), the tip of which contour is directed towards the grip region (3) of the flange (1). Provided in the grip region (3) of the flange (1) is an oval opening (15) by means of which the overlying grip region (4) of the cover layer (D) can be lifted from the flange. A support element (16) that is angled with respect to the plane of the flange (1) is arranged in the grip region (3) of the flange (1). An angled grip element (18, 19) for facilitating the handling of the blister pack is arranged at the edge of the flange (1) on both sides of the hollow chamber (C). The base portion (B) is so shaped that the blister packs can be nested in pairs with their undersides one inside the other, in each case the hollow chamber (C) of one blister pack lying in the region of the grip region (3) of the other blister pack. The blister pack is extremely handy, space-saving and stable, requires only an extremely small amount of preserving solution and enables the contact lens it contains to be removed especially easily.

Abstract: A hanger for positioning an object such as electrical wire or an ornament in remote locations such as in trees. The hanger has a first loop shaped portion for releasably mounting the hanger on a support at a remote location. The first loop shaped portion is a synthetic organic resin having a memory such that after deformation thereof the first portion returns substantially to its original shape. A second loop shaped portion is integral with the first portion for holding an object such as a wire or an ornament; however, the second loop shaped portion is stiffer than the first loop shaped portion such that a pulling force applied to the object or to the second portion results in said first portion deforming and releasing the support while the second portion still holds the object. The first and second portions each form loops open at one end to facilitate positioning the first portion on the support and an ornament or wire in the second portion.

Abstract: In accordance with the present invention there is provided an apparatus for conveying a web. The apparatus is able to continuously stretch the web or continuously release the stretching forces from a web in the cross-machine direction. The apparatus includes two pairs of opposing belts (21a, 22a, 31a 32a) wherein each belts travels along an endless path. The pairs of belts diverge or converge from each other in the cross-machine direction. Each pair of belts comprises an upper belts (22a, 32a) and a lower belt (21a, 31a) which are adjacent to each other. Each of the upper and lower belts has a non-planar outer surface which contacts the web.
