Inventor: SIEBELS WOLFGANG
IPC: A61F2/30
Filed: 1992-05-22
Abstract: In order to guarantee the growing-in process of bone implants (10) made of metal without bone cement it is proposed that the metal prosthesis (10) be coated with a braided structure (11) of carbon fibres (21, 22) which is prepared by directly braiding the fibres onto the metallic body. This measure has the additional advantage that subsequent equipping of pre-fabricated metal prostheses is possible. <IMAGE>

Abstract: A catamenial tampon (10) for absorbing menstrual fluid includes a compressed pledget (12) having a major (14) and a minor (16) radius of curvature. Zones (18, 20) of different density fibers are arranged adjacent to each radius of curvature and the zones can extend substantially the entire length of the pledget (12). The pledget is constructed of absorbent fibers which according to one embodiment are enclosed by a cover (28). A withdrawal string (36) is attached to the pledget (12) and facilitates removal of the tampon from a woman's vagina. The absorbent is compressed into an elongated, generally cylindrically shaped pledget having a zone of high density fibers (20) and a zone of low density fibers (18). After compression, the low density fibers will expand and form a curved tampon (20).

Abstract: A ball valve for liquids, in particular for hydraulics, has a plug (4) which is accommodated in a housing (1, 24) between two sealing rings (27; 28), can be rotated by means of a shaft (6) arranged on one side of it, provided with a lever and aligned perpendicularly to the axis of the sealing rings (27; 28) and is mounted on the said shaft and on a pivot (5) arranged on the other side of the plug (4) and aligned with the said shaft, with sealing (15, 16) being provided relative to the housing (1). The sealing rings (27; 28) are arranged as pistons in a cylindrical housing part (24), being pressed against the plug (4) by the pressure of the liquid. In order to reduce the frictional adhesion between the plug and the sealing rings in the case of back pressure, this adhesion having to be overcome to open the valve, the housing space (36) to the outside of the plug (4) and between the two sealing rings (27; 28) is connected to the delivery side and/or the side on which the consuming unit is situated by a conduit controlled by a valve that can be actuated from outside, or arranged between the two sealing rings (27; 28) is a spacer (46) of a length such that, when the sealing ring (27) on the delivery side is resting against the plug (4), it holds the sealing ring (28) on the side on which the consuming unit is situated away from the plug (4) and vice versa. <IMAGE>

Abstract: A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50 DEG  C. and 90 DEG  C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

Abstract: For performing the non-destructive inspection of articles, such as thick articles made of a composite material, having a distributed porosity, an apparatus is used comprising an ultrasonic inspection head (10) and an associated electronic assembly. The inspection head comprises at least one pair of ultrasonic sensors (C1 to C8), distributed over a circle, and all focusing at the same point (P), under fixed incidence with respect to the surface of the article. The electronic assembly controls the sensors so that they are all simultaneously transmitters, then all simultaneously receivers. The output signals then emitted via the sensors are added in a summation circuit ( SIGMA ) which amplifies the echoes resulting from the defects of the delamination type, and it substantially attenuates the echoes due to the porosity, by an averaging effect. <IMAGE>

Date Jun. 25, 1992.This invention relates to the formation and use of a variable, multilayer system of discrete, discontinuous and nonsequential molecular sieves, comprising of agarose-acrylic gels of distinct composition. Each of the individual gel-layers of the system is designed according to partition and/or retardation coefficients for specific retention and therefore selective separation of selected molecules of different molecular sizes. The unique multilayer composite acrylic gel system of this invention makes it possible to separate micro- and macromolecules which differ in molecular weights by millions of daltons. So isolated any physically defined molecular groups are superiorly suitable for further chemical, physico-chemical or biological characterization.
