Abstract: The cutting and pinching device is fixed onto one of the bases (13) which are distributed on the star-configured support element (12) in each of two reels of the winder. When the empty reel comes into the winding position, the extreme portion (42) of the product to be wound passes into a position tangential to the flap (17) opposite the blade (30) of the cutter. When the jack (24) is actuated so as to bring the flap (17) back into a position parallel to the corresponding sector (14), the extreme portion of the elongate product is pressed against the cutter (30) while the pinching lever (32) is lowered onto the initial segment of the elongated material adjacent to the extreme portion. The initial segment is pinched against the interior face of the barrel segment (19) and passes between this barrel segment and the adjacent segment in order to wind the barrel and permit the formation of the new reel (41). <IMAGE>

Abstract: Leu-3<-> cells surviving infection with the AIDS retrovirus can be induced with IUdR to express infectious virus. A cellular clone (8E5), isolated by limiting dilution of a mass culture of survivor cells, was found to contain a single, integrated, defective provirus that was constitutively expressed. Although IUdR treatment of 8E5 cells failed to induce infectious virus, cocultivation with Leu-3<+> cells generated the characteristic syncytia associated with acute AIDS retrovirus infection. The single integrated copy of proviral DNA directs the synthesis of all major viral structural proteins except p64 and p34 as monitored by immunoblotting. Diagnostic reagents and kits in accordance with the present invention are also described.

Abstract: The invention relates to a seal, consisting of an elastomer shaped ring, which is to be pushed onto a cylindrical circumferential surface and supports itself on the latter by a radially acting sealing surface, with an embedded inner ring, consisting of a chamber portion, likewise to be pushed onto the circumferential surface, with a sealing chamber, which surrounds the shaped ring, is undersized relative to the outer contour of the shaped ring and conically widens from the clear inside diameter of the chamber portion toward one face of the chamber portion, and consisting of fastening means which fix the chamber portion with respect to a second surface resting against the face of the chamber portion. For sealing off a cylindrical surface with respect to a second surface standing vertically on the cylindrical axis, it is proposed that the shaped ring have an axially acting sealing surface, preferably lying at right angles to the radially acting sealing surface, for contact with the second surface.

Abstract: A chemical pretreatment method is used to produce boron carbide-, boron-, and boride-reactive metal composites by an infiltration process. The boron carbide or other starting constituents, in powder form, are immersed in various alcohols, or other chemical agents, to change the surface chemistry of the starting constituents. The chemically treated starting constituents are consolidated into a porous ceramic precursor which is then infiltrated by molten aluminum or other metal by heating to wetting conditions. Chemical treatment of the starting constituents allows infiltration to full density. The infiltrated precursor is further heat treated to produce a tailorable microstructure. The process at low cost produces composites with improved characteristics, including increased toughness and strength.

Abstract: In the case of many machine elements, for example rolling bearings or rolling drives, which are subjected not only to rolling stress but at the same time also to sliding stress, this results in sliding wear in certain zones. In order to reduce this as far as possible, it is proposed to apply to the affected surfaces of such structural units a layer of a sliding bearing material which, however, according to the perception of the invention, has to be applied by a PVD method and has to be of a thickness of the order of magnitude of the surface roughness of the base element; known thicker sliding bearing coatings are not suitable.

Abstract: This invention relates to a sanitary tampon prepared by forming strings from a menstrual blood absorbing material having high water absorptivity, such as absorbent cotton, weaving the strings to form a tampon base material and compressing a tampon body formed from this base material by applying thereto an external force in a bullet-like shape. This tampon has a large surface area and a large number of voids formed by the stitches. Therefore, it can efficiently absorb the blood when used, and each of the strings absorbing the blood rapidly swells independent of the others so that they return to a state before the compression and can reliably absorb the blood flowing down along the vaginal wall. The tampon can be taken out easily because the stitches of the tampon body are crushed by the inner wall of the vaginal opening and its surface area becomes small.

Abstract: A predistorter is connected upstream of a high-frequency amplifier to be linearized. A predistortion factor is adaptively modified in the predistorter in such a way as to compensate non-linearities of the amplifier as well as possible. The quotient of the output signal of the high-frequency amplifier and the input signal of the predistorter is produced first. An average amplification is then determined based on the signal quotient. A correction term is produced for the predistortion factor, this correction term being dependent on the extent of the deviation of the average amplification from a set value. The predistortion factor is adaptively modified in such a way as to minimize the correction term.
