Definitions
- the invention relates to a device for mixing / separating substances different mass and / or density with at least one for which These substances contain certain containers in a holder is held, which is carried by a drive unit together with the motor of the container is movable, the container or the holder by means of Drive unit along an open or closed cycle Path of motion with at least two areas of strong curvature change or at least two reversal points with in these areas or reversal points the large path acceleration takes place essentially tangentially can be guided back and forth according to the preambles of claim 1.
- samples have to be examined that consist of liquids of different weights Contain particles. Often, particles of different weights must be used intimately mixed with one another or mixed particles are also separated what purpose these samples are filled into containers and according to the known State of the art stirred or whisked or shaken or when desired Separate the samples in centrifuges by moving them quickly on a Circular orbit are centrifuged. The heavier ones migrate during a separation Components outside and the lighter components remain closer to that Center of circular motion. But it is known that a long time constant Force on the samples, as is the case with centrifugation, for one Series of substances is disadvantageous.
- DE-2354368-A1 describes a device for centrifugal separation Liquid is known in fractions of different density, which is a separation container has mounted on a centrifuge motor and by this is moved in an orbit around a first axis.
- enclosing housing is rotatably arranged about a second axis, so that overlap both rotary movements with respect to the separation container.
- the point of the separation container always keeps the same distance from the first axis at.
- DE-1432853-A1 describes a method and a device for separation of substances made known by gyrofugation, in which a closed Container rotates around two different axes.
- a centrifuge for separation has become known from US-A-2,222,266 and regrouping of particles.
- the centrifuge has several drivable ones Axes around which the particles to be centrifuged can rotate simultaneously so that the particles have a superimposed, compound trajectory run through.
- US-A-4 146 364 discloses a method for mixing substances of different mass located in at least one container and / or density is known, which is held in a holder, which is moved by a drive unit taking the container with it the container along a cyclical open movement path in these reversal points of great orbit acceleration by the Drive unit, excluding rotation of the container, essentially is moved tangentially back and forth.
- the present invention has for its object a device for Mixing or separation of either to be mixed or separated To create substances according to the type mentioned at the outset, the one Allow improved mixing or separation of components that otherwise difficult to mix or only a slight difference when separated in specific weight, the device for many Applications should allow improved sample treatment.
- the drive unit from at least two eccentrically rotatably mounted eccentric wheels or There are eccentric rollers which are driven synchronously and which are constant Form gap, within which a carrier is guided, which is on its lower end, located below the gap, is pivotally supported is and the at its upper, above the gap end Carrying holder for the container, the rotation of the eccentric wheels Gap moves back and forth with the carrier.
- the invention makes use of the effect that in Reversal points or in parts of strong changing curvatures accelerating forces acting on the particles become very large and for a reversal of movement by 180 degrees even go towards infinity, if only the time for the reversal of movement is made sufficiently short. Therefore at Use of the device even with very poorly mixing substances or in the separation of mixed substances even with small differences in the mass and / or density an optimal mixing or Separation guaranteed.
- the device according to the invention is particularly suitable for mixing Suitable substances of different masses and / or densities that only difficult to mix.
- the invention is also for separating substances by mass and / or density is suitable, in which case a brief application of force for the separation of particles, interrupted by phases without significant force, as is made possible by the device according to the invention, results in no or practically no negative influences, but in many cases with regard to further analyzes or aftercare of the Samples can benefit them.
- the container is elongated in shape of a sample glass and extends in its longitudinal extent in Direction of the path of movement on the holder, with the sample glass in Essentially tangent to an open trajectory along a part an arc with a given radius (r) and two reversal points or along a straight line with two reversal points at the ends of each Trajectory is moved back and forth.
- r radius
- the container can also be along an ellipse or along an " ⁇ " with each two areas of strong curvature change on a closed Trajectory or along a semi-ellipse with an area stronger Path curvature change and two reversal points on an open trajectory as well as with a given radius (r) on a spherical shell be moved back and forth essentially tangentially.
- the long axis to short axis ratio is a large number.
- the bracket can be along a semi-ellipse with an area strong change in curvature and two reversal points.

- the drive unit exists when there is a large path acceleration in an advantageous manner from at least two eccentrically rotatably mounted Eccentric wheels or eccentric rollers which are driven synchronously and which form a constant gap, a carrier is guided within it is the pivotable at its lower end located below the gap is supported and at its upper end, above the gap carries the holder for the container, the rotation of the eccentric wheels Gap moves back and forth with the carrier.
- the drive unit consist of two gears, their axes of rotation at a distance from each other rotatably mounted in walls and by means of a Toothed belts are driven synchronously, with the same on each gear Eccentricity an eccentric is arranged between the constant ones Define gap within which the carrier is guided, which of its lower pivot point up to the holder of the container the length of the Radius (r) defined, the container being arranged tangentially to the carrier.
- the major path acceleration is above the Drive unit having eccentric rollers, a second such drive unit arranged with eccentric rollers offset by 90 degrees, whereby each the carrier is guided between the lower and upper eccentric rollers, which is designed as a round bar and gimbal at its lower end is attached, the lower one formed when the eccentric rollers rotate and upper gap, mutually overlapping and partially offset by 90 degrees walk back and forth with the wearer; the roller pairs rotate on gap.

- the DC motor is advantageously for speeds between 30 and 500 revolutions per minute, preferably between 60 and 300 Revolutions per minute. These speed values result in Consideration of the translation of the rotary movement into a double stroke movement of the carrier with the sample containers an optimal number of movements per unit of time, which is preferably between 100 and 200 double strokes per minute. Double stroke means the movement of one Reversal point on the open path of movement of the wearer to the other Turning point and back to the first turning point. Preferably one revolution of the engine results in a double stroke of the carrier.
- a contains Storage device a program that queries the controls and controls the drive unit according to their position.
