Abstract: Abstract of the Disclosure The invention relates to a dosage regimen for emergency contraception, to pharmaceutical compositions of the same purpose, to the use of levenorgestrel for the manufacture of pharmaceutical compositions for the same purpose, as well as to the manufacturing process of these pharmaceutical compositions. According to the invention the emergency contraception carried out by the use of levonorgestrel as active ingredient is characterised by administering a single application dose containing 1.5 ± 0.2 mg of levonorgestrel as active ingredient up to 72 hours after the coitus. The pharmaceutical compositions for emergency contraception according to the invention contain only 1.5 ± 0.2 mg of levonorgestrel as active ingredient in each application dose in admixture with known excipients, diluents, flavoring or aromatizing, stabilizers, as well as formulation-promoting or formulation-providing additives, commonly used in the pharmaceutical practice.

Abstract: A surgical tool to create a recess for an artificial joint in cartilaginous and/or bony tissue, and particularly for an artificial acetabulum in a hip-joint bone, is described which has an essentially hemispherical superficies 10 and a hollow interior space 50 bounded by this surface where at the superficies 10 are formed at least one cutting edge 20 extending from the pole 12 of the superficies 10 to the equator 14 of the superficies 10 and having at least one cutting element 20 with one cutting surface 26 turned toward the workpiece and one cutting surface 28 turned away from the workpiece, as well as one opening 22 in the superficies 10 cooperating therewith to evacuate the chips toward the hollow interior space 50, where for rotation around the axis of symmetry which forms the axis of rotation, a bearing shaft 40 extending through the hollow internal space 50 is fastened at the superficies 10 and where a clearance angle &ggr; of the cutting edge 20 subtended between the superficies 10 and the cutting surf

Abstract: A bone marrow rasp for forming bone cavities, particularly in femurs, having a tubular hollow body which is open at its distal end for the axially directed reception of bone material, has openings formed along its circumference which are in communication with the hollow space for the discharge of lateral bone material, and is connected along its outer surface with rasp elements which protrude beyond the outer surface and at least partially cover the openings.

Abstract: There is disclosed a pneumatic driving device having a cylindrical housing in which a piston element is axially displaceable. The piston element has at its ends a front piston and a rear piston which are connected to each other by a connecting pipe. A switch element is mounted in the housing between the pistons and defines a variable front chamber with the front piston and a variable rear chamber with the rear piston. Two inlet openings acted on by pressure are formed in the housing and can be connected with the front and rear chambers respectively. The switch element, in a first position, frees the inlet opening to the rear chamber so that the rear piston travels axially outward and the front piston axially inward and, in a second position, frees the inlet opening to the front chamber so that the front piston moves axially outward and the rear piston axially inward. The inwardly moving pistons reverse the switch element between the two positions.

Abstract: An arrangement provides for the wireless transmission of a measuring signal from a sensor to an evaluating unit by a pair of first electrical coils that are temporarily inductively coupled with one another. The sensor is supplied with energy by a second pair of electrical coils that are also temporarily inductively coupled with one another. The sensor includes a power supply circuit means for receiving a low-frequency energy signal from the second pair of electrical coils and supplies an energy signal to a transmitting oscillator means. The transmitting oscillator means responds to at least one measured physical quantity and provides a medium-frequency measurement signal to be transmitted over the first pair of electrical coils. When used in a tire pressure control system, this arrangement provides for a reliable transmission of signals over a relatively large transmission path without strict mounting tolerances, while complying with governmental regulations.

A central core is provided at a center-point of the concentrically arranged recesses and side walls. The base of the cylindrical shell core has appropriate thickness below each recess to minimize radial tapering of magnetic flux.

Each bowl 2 has two chambers 3a, 3b connected with each other for free flow communication from either chamber to the other. One chamber 3a lies above the other 3b and is of a sack shape with a radially outwardly projecting closed bottom so that on stoppage of rotor rotation liquid therein flows back into the more deeply-lying other chamber 3b. The bowl 2 is light-transparent for photometric measurements.
