Abstract:
A grey water tank mounting and control arrangement for the recycling and storage of used water contains three plastic tanks constructed as individual standing units, which can be mechanically connected to one another and to a control unit. The tanks and the control unit contain orienting means so as to permit mutual orientation thereof in such a way that they can be fixed to one another in the correct position.
Abstract:
A hand tool (1) having a drive motor (12), a depth stop (16) by which the drive motor (12) can be automatically switched off when it is in contact with a workpiece (4), and a switching mechanism (21) in an electric circuit (22). The electric circuit (22) includes a switch (24) for switching the drive motor (12) on and off, a first contact element (25) for reversing the polarity of the drive motor (12) and a second contact element (26) for switching off the drive motor (12) by the use of the depth stop (16). Also, a switching device (32) is connected to the drive motor (12) and is integrated into the electric circuit (22) so that the switching device (32) is arranged in a branch line (31) bypassing the second contact element (26) and by which the second contact element (26) can be bypassed in an open operating position caused by the depth stop (16) by actuation of the first contact element (25) for reversal of the direction of rotation of the drive motor (12), which makes it possible to switch the drive motor (12) from clockwise to counter-clockwise rotation or the reverse without the necessity of mechanical elements and without the necessity of any manual manipulation of adjustment elements.
Abstract:

The operator unit has a guide for a paint line, via which the spray head is supplied with paint, the operator unit comprises a signal transducer for generating a control signal, the operator unit has a control connection for a control line, a barrel is arranged between the operator unit and the spray head, and an air stream is led from the operator unit to the spray head through the barrel.
Abstract:
The present invention relates to a method for equalizing the orientation of fillers and/or distribution of fillers in a molding compound comprising filled plastic material of an injection molded part. A method of this type is required in particular during injection molding.The method according to the invention is characterized in that the injection mold and the molding compound are supplied with sound during injection molding in the injection mold. The sound has a frequency in the range of the spectrum of the first ten natural frequencies of the filler-matrix system. By supplying with this sound, the fillers, for example fibers, are distributed within the injection molding compound in a more isotropic manner with respect to their orientation and distribution so that significantly better mechanical and optical properties of the injection molded part are produced.
Abstract:
In a device (1) for stirring and for dosing the mixing ratio of different kinds of liquid (2), in particular of paints (3) and a thinning agent (4), consisting of a stirring rod (6) and a reservoir container (5) in which the liquids to be mixed together are filled, it should be possible to measure the amount of liquid (2) to be added in relation to the amount of fluid (2) already contained, and to do so in a quick and easy manner using the stirring rod (6).This is achieved in that the stirring rod (6) has got at least two measuring openings (11) worked into it, which are spaced apart in the direction of the lengthways axis (7) of the stirring rod (6), and that the dimension of the particular measuring opening (11) measured parallel to the lengthways axis (7), and the measuring web (12) remaining between two adjacent measuring openings (11), are configured in relation to the fill level of the liquids (2) that are put into the reservoir container (5), or at least one jacket surface of the stirring rod (6) has got one or more measuring bodies (13) formed on it, which are spaced at intervals from one another in the direction of the lengthways axis (7) of the stirring rod (6) and in relation to the fill level in the reservoir container (5), and that the dimension of the measuring bodies (13) running in the direction of the lengthways axis (7) of the stirring rod (6) is configured in relation to the fill level in the reservoir container (5).
Abstract:
An apparatus for delivering a viscous material by means of an eccentric screw pump, includes a framework for carrying and fastening apparatus elements, a pump-housing portion for carrying a stator and a rotor in the form of a delivery screw, suction and pressure regions for introducing and discharging the delivery material, respectively, an electric drive unit for driving the rotor in the stator in a first direction of rotation for delivering the delivery material, a control mechanism for activating the drive unit, and one or more releasable retaining members for the rotationally fixed and/or positionally fixed connection of the drive unit and of the stator. A change in the direction of rotation to a second direction of rotation of the electric drive unit, with the retaining mechanism released, gives rise to automatic separation of the pump-housing portion with the stator by virtue of the rotor being unscrewed.
