Patent DE-19751729-A1 (DE)
Inventor: STAHL HERMANN
IPC: F04D29/30
Filed: 1997-11-21
Abstract: The invention relates to a fan wheel for a turbocharger. The fan wheel (1) consists of a base body comprising a central axis of rotation (5) formed by two congruent opposing cover discs (2, 3). Fan blades (6) are arranged between the front faces of the cover discs facing each other. The fan blades (6) are formed by a single piece on at least one of the cover discs (2, 3) and comprise an axial locating face (30) on which an opposing axial locating face (31) of the other cover disc (2, 3) is located. Fixing means are provided in the area of the locating faces (8, 9) for non-detachable interconnection of the cover discs (2, 3). In order to manufacture the fan wheel (1) without balancing, the cover discs (2, 3) are made of material that is suitable for stamping and the fan blades (6) are stamped axially from the material of a cover disc (2, 3). The edges (22a, 22b) between the plane of the cover disc (2, 3) and the side wall (19a, 19b) of the fan blade (6) standing substantially at a right angle in relation to the plane of the cover plate (2, 3) and the edge (21a, 21b) between the side wall (19a, 19b) of the locating face (30, 31) are rounded with a radius (R1, R2) of approximately 0.5 to 2 mm.

Title: Measuring apoptosis in mammalian cells
Inventor: STEINLEIN PETER DR
IPC: C12Q1/6897
Filed: 1997-11-28
Abstract: Method for measuring apoptosis comprises transiently transfecting mammalian cells with two plasmids, one containing a DNA sequence being tested and the other a sequence encoding a fluorescent marker protein (MP). The cells are incubated, then fixed and DNA and cell fluorescence measured to determine, respectively, the proportions of apoptotic and transfected cells, and from these results the proportion of apoptotic cells in the transfected subpopulation calculated. The first plasmid contains a sequence being tested either for the pro- or anti-apoptotic activity of its encoded protein (I) or to determine if, or by which substances, its activity (or that of (I)) can be modulated. The transformed cells are cultured for long enough for the DNA sequence, or (I), to exert its action on apoptosis, then harvested and fixed such that MP is retained in cells but DNA fragments produced by apoptosis diffuse out of the cell.  An Independent claim is also included for a kit for this process.
Patent DE-19755015-A1 (DE)

IPC: D04B1/24
Filed: 1997-12-05
Abstract: The hosiery garment has a welt (7) with at least one field worked into it, at least at one part of its periphery, which extends over several rows of stitches and wales. The field has rows of stitches with at least one floating yarn (15) which restricts the stretch in the peripheral direction. The floating yarns (15) are knitted into the stitches flanking the structured fields, and can be cut where they float to increase the stretched width of the welt. At least one field (14) with floating yarns (15) extends over the width of the welt (7) across the peripheral direction. The welt (7) has a knitted edge, turned over if required, which is free of the floating yarn fields (14). The floating yarns (15) lie on only one side of the knitted material, at the inner side of the welt (7), and they have a different color and/or structure from the other yarns in the knitted hosiery and have a different dye take-up or reject dyestuffs, or contain a dye repellent. Outside the fields (14), the floating yarns (15) are knitted in with the other stitches at least partially as plain-knit single jersey rows. The stitch loops of at least one ground yarn extend into the fields (14) with floating yarns (15). The knitted material has at least one elastomer floating yarn, knitted in with the ground yarn in a single jersey knit. A second ground yarn has the stitch loops extending in the fields (14), and the fields (14) are knitted with a third ground yarn in a plain-knit single jersey, and are knitted together with the stitch loops at the sides of the fields. The knitted material, outside the fields of floating yarns, has at least rows of stitches in the order of single jersey 2:2 tuck and 2:2 float, single jersey 1:1 tuck, single jersey plain-knit, and single jersey 1:1 tuck. The knitted structure within the fields of floating yarns has rows of stitches in the order single jersey 2:2 tuck and 2:2 float, single jersey plain-knit, single jersey 1:1 tuck, and floating.
