Abstract: A doctor blade device for the removal of dampening medium from a soft surface of an ink applicator roller in the inking unit of a printing machine, having at least one doctor blade placed against the surface of the roller and having an edge radius in the range of 2 mm to 10 mm.

Abstract: An anilox inking unit for an offset printing machine having an anilox roll having a rotation direction and a fluid blowing device arranged along the anilox roll . The blowing device is disposed downstream of a working doctor with respect to the rotation direction of the anilox roll and upstream of the ink transfer point. In accordance with one embodiment, the fluid being blown by the blowing device is ambient air.

Abstract: Molecular sieves are modified by an ion exchange process where metal cations are introduced into the molecular sieves by means of solid state ion exchange. The solid state ion exchange can be carried out as follows: a weighed amount of calcined and activated zeolite is intimately mixed with a precalculated amount of PtCl.sub.2, PdCl.sub.2, RhCl.sub.3, CuCl.sub.2, V.sub.2 O.sub.5 or another compound of the noble metals (e.g., corresponding halides or oxides), the solids mixture is then heated in a current of inert gas (e.g., a current of helium gas or of nitrogen) to temperatures of 400.degree. to 600.degree. C., then cooled down to room temperature and subsequently reduced in a current of hydrogen for 10 to 14 hours at 280.degree. to 350.degree. C. in order to produce small metal clusters from the cationically introduced metal.

Abstract: The invention is directed to a luggage rack for vehicles, especially aircraft, which is subdivided into individual compartments by means of separation walls and is arranged in the longitudinal direction of the vehicle with an overhead configuration with respect to the passengers and whose individual compartments are respectively closeable by means of a lid.

Abstract: A process and a device for regulating the stimulation frequency of heart pacemakers are disclosed. The process comprises generating with the aid of light emitted by a light-emitting element, reflected by the blood of a patient, and received by a light-receiving element, a current flow which causes, in a measuring probe, an increasing of the current flow at a constant probe voltage or a damping of the probe voltage at constant current flow. Thereafter, one of the possible changing values is measured and the change, with time, is evaluated as a measured quantity proportional to the change, with time, of the blood oxygen saturation, and, as a function of the measured quantity, the stimulation frequency of the heart pacemaker is regulated in such a manner that the greatest possible blood oxygen saturation is always achieved with the lowest stimulation frequency.

Abstract: A Cardan gear assembly having an output centerpoint means which moves along an elliptical path. A force transfer means connects the output centerpoint to a means operative to carry a work performing means. The major axis swept out by the means operative being skewed with respect to the major axis of the ellipse which is swept out by the output centerpoint. As a result, the work performing means will be swept along a curve which is of a portion of a helix as well as part elliptical. This curve takes the form of a partial helix wherein the outgoing path is different from the return path.

Abstract: A cardiac pacemaker includes means for conforming the stimulation frequency to the bodily stressing conditions of the wearer of the pacemaker in using a blood parameter as measuring value for the influencing of the frequency of stimulation. A measuring probe is implanted in the heart of the wearer of the pacemaker for measuring the oxygen saturation of the blood. The measuring value thereby resulting serves as measuring parameter for the influencing of the frequency of stimulation.
