Bobbin holder with rotatably mounted centring plates. In the known bobbin holders, the centring plates are cylindrical and are matched to the tube inside diameter. To clamp the tube, they therefore have supporting rings, the diameter of which is equal to the tube outside diameter or larger than this. If inaccurately calibrated bobbin tubes are used, there is the risk of inaccurate clamping. The ne...

A system of navigation for vehicles is proposed, which is provided with a device (14) for representing a road map as well as with a composite navigation apparatus (10, 11, 12) for the continuous instantaneous determination of the location of the vehicle and with a location display (16) on the representation of the road map. Deviations of the location from the course of the roads on the road map ar...

PURPOSE: To count the number of particles accurately by several scanning also for a threshold corresponding to a small particle by calculating a conversion for mapping the measurement position of a particle that is detected at one time to a corresponding position on the surface at another time.

The invention relates to a layer of polyurethane of high optical quality exhibiting the properties of an energy absorber and of resistance to scratching and abrasion, and it is characterised in that it additionally exhibits improved misting resistance properties, the polyol component employed to form the layer comprising a long polyol containing ethylene oxide blocks. The polyurethane layer i...

In a process for the continuous fermentation of beer wort with yeast retention, the wort used for the fermentation is introduced free of oxygen into the fermentation and the oxygen required by the yeast is metered in such a way that it can be immediately consumed by the yeast. As a result, the aroma retention and the aroma stabilisation are ensured in the continuous production of beer.

The invention relates to a process for the production of mouldings from flexible integral polyurethane foam (for example headrests, armrests and flexible rear spoilers) having a density of from 0.3 to 0.8 g/cm<3>, in particular from 0.3 to 0.6 g/cm<3>, by foaming the polyol component (component A) with the isocyanate component (component B) in the presence of a blowing agent (component C). The ess...

The heel holder comprises a bar (1), which is arranged swivellably or rigidly on the ski, and an angular, two-armed thrust member (8), whose shorter arm (9) serves as sole holder while the longer arm (10) receives the release mechanism. The latter comprises a spring (12) and a coupling (21), which is provided at the upper end of the thrust member (8). The coupling is swivellable in relation to the...

An umbrella with a protective covering is described, which protective covering is guided so as to be longitudinally displaceable on the umbrella stick and is mounted in the state of non-use above the opened-out umbrella canopy around a continuation of the umbrella stick.
