Abstract: A rotatable impeller (49) for stirring liquids contained in tanks. Strip-like blades (50) of simple form radiate from a central hub (51), in swept-back configuration relative to the direction (54) of rotation. The blades are angled relative to the hub so as to exert a forward and downward force upon the liquid as the impeller rotates, and the blade curvature is such that the area projected upon the liquid by the solid structure of the rotating blade is less than the corresponding area that would be projected by an otherwise similar blade in which imaginary straight lines connected all adjacent vertices, and any void areas lying within the boundaries of those imaginary lines had been filled in. The preferred arrangement of the blades is such that when the impeller is arranged with its axis (67) vertical, curvature of each blade along its length is such that it extends away from the hub in a diminishing downward curve, reaches a lowest point (70, 71 Fig. 10), and then rises again before the blade tip (58) is reached. In cross-section each blade will typically be straight and parallel-sided, but may also be slightly curved (68), of aerofoil section (69), etc.

Abstract: The previously known co-extrusion heads are suitable only for processing thermally stable polymer melts, such as for example PP and PE, because they can be moulded into tubes on manifold sleeves having the known heart-shaped groove distributions. Thermally sensitive polymers, such as for example PVDC and PET, but in particular rigid PVC, cannot be processed in the known co-extrusion heads, since the material would stagnate in the transitional area of the open manifolds and decompose within a short time due to the effect of heat. The co- extrusion head according to the invention also permits the processing of, for example, rigid PVC by a combination of the mandrel support principle, by which a rigid PVC strand introduced into the extruder head at the top is formed into a tube, with the heart-shaped groove principle, by which material strands of another material introduced into the interior of the rigid-PVC tube are processed, for example to form a barrier layer tube and to form adhesion promoter layer tubes. <IMAGE>

Abstract: A mechanical seal with a cooling device (6), surrounded by the seal housing (6), which cooling device (6) emits the heat which is produced by friction of the sliding rings (3, 4) and is passed into the seal housing, possibly by conduction and convection, by means of a cooling medium, guided in the circuit, via a heat exchanger (10) to cooling water which passes through the said heat exchanger (10). The heat exchanger (10) has an essentially hollow-cylindrical design and contains cooling tubes (16), running on parallel axes between two annular tube bases (14, 15), and an outer wall (17a) and an inner wall (13), in each case connecting the tube bases, which, in their totality, bound a chamber to which the cooling water is supplied. The inner wall surrounds the sliding ring (4), which is held such that it cannot rotate on the seal housing (6), and its supporting sleeve (4a), and the sliding ring (3), which rotates with the shaft (2). The sliding ring (3) has, on its circumference, an external thread (11a) which is surrounded by an internal thread (11b) on the inner wall (13). The two threads form a pump device which conveys the cooling medium in the circuit through the interior of the cooling tubes and to the sealing gap of the sliding rings (3, 4) and to an annular magnetic filter (12). The magnetic filter is arranged on an end-face, removable cover (7) of the seal housing. <IMAGE>

Abstract: In magnetic resonance imaging where a subject is placed in a static field and the subject is selectively excited by applying an RF magnetic field in the presence of a gradient magnetic field, the peak RF power of the RF magnetic field is reduced by decreasing the peak amplitude of the RF magnetic field while concurrently reducing the magnitude of the gradient magnetic field. The incremental time duration for the RF magnetic field portion which is reduced in amplitude is proportionately increased. In using an RF pulse having front and back sidelobes with a positive lobe therebetween, the duration of the RF pulse can be reduced by increasing the magnitudes of the sidelobes and concurrently reducing the time periods of the sidelobes. A minimum SAR embodiment can be realised.

Abstract: A polymeric liquid crystal composition comprises a polymer mesomorphic compound having an asymmetric carbon atom and a low-molecular weight mesomorphic compound. The composition can be easily formed into a film of a large area, shows a response speed which is not substantially different from that of the low-molecular weight mesomorphic compound alone and stably retains alignment resistant to pressure or heat impact. Such a good alignment is especially obtained when the polymeric liquid crystal composition is incorporated in a liquid crystal device by being disposed between a pair of substrates preferably having an alignment face provided with an orientation characteristic for aligning the molecular axis of the liquid crystal composition in one direction. It is suitable that the polymer mesomorphic compound is optically active and has a helical rotation direction opposite to that of the low-molecular weight mesomorphic compound.

Abstract: The invention relates to a floating-point digital-to-analog converter (DAC) having mantissa converting means and exponent converting means. The mantissa converting means generally has higher accuracy than the exponent converting means because of differences in their constructions. Hence, as long as the accuracy of the mantissa converting means is greater than that of the exponent converting means, analog output of the mantissa converting means is used as output of the DAC. Once the accuracy of the mantissa converting means goes below that of the exponent converting means, the input data is shifted to form digital mantissa applied to the mantissa converting means, and the exponent converting means multiplies the output of the mantissa converting means (i.e., analog mantissa) by weight specified by the exponent. Thus a higher accuracy can be achieved than in a conventional apparatus.
