摘要:
A rotor blade coupling device (9) comprising a torsionally rigid carrier (4) is disclosed, the carrier (4) being mounted in a manner which is free of centrifugal force between a thrust bearing (3) and a control bearing (5), resilient impact and pivoting movements of the rotor blade coupling device (9) being able to take place in a damped manner. The rotor blade coupling device (9) is clamped between a rotor head star (101) and a rotor head central piece (102) and held rotatably about the rotor axis A. The centrifugal forces which occur, are transmitted from a rotor blade holder (2) to the rotor head star (101) and thus kept away from the carrier (4).

The measurement transducer includes at least two oscillatably held transducer tubes vibrating, at least at times, during operation, of which at least one transducer tube serving to convey at least a volume portion of a medium to be measured, communicates with a pipeline; as well as at least one transducer element for converting electrical energy into mechanical and/or vice versa. The two transducer tubes are mechanically coupled together by means of at least one, inlet-side, coupling element and by means of at least one, outlet-side, coupling element in such a manner that both the inlet-side coupling element, as well as also the outlet-side coupling element, are subjected during operation repeatedly to deformations which correspond to vibrations of at least one of the two transducer tubes for converting electrical energy into mechanical, oscillatory energy and/or vice versa. The transducer element, especially a transducer element formed by means of a piezoelectric, deformation body, and at least one of the coupling elements, are, at least mediately, mechanically coupled together in such a manner that the transducer element executes, at least in part, oscillatory movements, which correspond with the repeated deformations at least of this coupling element.
摘要:
An observation port (4) in a primary structure (13) of a helicopter cabin (0) is disclosed, which is arranged between a pilot's seat (2) and a co-pilot's seat (3). The observation port (4) is delimited from the interior by an inner screen (15), and from the atmosphere by an outer screen (16), wherein the pilot can observe the space underneath the helicopter cabin (0) through the observation port (4). As a result of the configuration of the observation port (4) the pilot can assume an ergonomic and relaxed seating position at any time, even when he is executing flights with suspended loads. By means of the observation port (4) and the windows (15, 16), which extend laterally between the two pilots' seats (2, 3), a novel unrestricted vertical visual frame of reference onto the suspended load is achieved, wherein the length of the load cable has practically no influence.

An anti-D immunoglobulin G-preparation is produced in high-yield from human plasma containing anti-D IgG, or a plasma fraction containing an anti-D IgG, in which (A) the plasma, or the plasma fraction, with a pH in the range of pH 3.5 to 6.5 and a conductivity value in the range of 2 to 4 mS/cm, is subjected to ion exchange chromatography with an adsorbent which has carboxymethyl groups as functional groups, the anti-D IgG being bound to the adsorbent, (B) the adsorbent with the bound anti-D IgG is first rinsed with a wash solution at a pH in the range of 5 to 8 and a conductivity value in the range of 2 to 4 mS/cm, and the anti-D IgG is subsequently eluted, and further (C) the eluted anti-D IgG at a pH in the range of 6 to 8 and a conductivity value in the range of 2 to 4 mS/cm is treated with an alkaline adsorbent with ion-exchange characteristics in order to bind undesired components, and finally, the anti-D IgG is concentrated. The non-infectious anti-D concentrate thus obtained possesses a high specific activity of more than 1% anti-D IgG per gram of total IgG.
