Abstract: The invention relates to an axial fan with an essentially cylindrical outer housing and with a fan wheel which rotates therein and the hub of which is located on the rotor of an electric drive motor, the stator of the drive motor being held by webs extending on the delivery side relative to the outer housing. The vanes of the axial fan are radially twisted and possess a forward curvature with a camber varying from the hub cross-section to the outer cross-section. In order to achieve a pressure increase, at the same time with a reduction of the operating noise, the vanes have in the hub region a cross-section designed for a low flow per unit volume and small pressure increase, but in the outer region a cross-section designed for higher values of flow per unit volume and pressure increase.

Abstract: In a continuous process for the preparation of phosphorous acid with simultaneous production of hydrochloric acid, a reaction zone is provided which is in open communication with a first scrubbing zone. A portion of the reaction product is recycled from the bottom of the reaction zone into the top of the scrubbing zone and phosphorous acid is removed from the circulation. Hydrogen chloride gas escaping from the top of the first scrubbing zone is brought into contact, in a cooled, second scrubbing zone, with an overstoichiometric amount of water. Hydrochloric acid is obtained which is passed as starting material into the reaction zone or into the top of the first scrubbing zone. The external cooling of the second scrubbing zone is controlled such that the temperature in the reaction zone is kept constant at a desired value between 90 DEG  and 130 DEG  C. without adding any external cooling or heating energy. Pure hydrochloric acid is recovered in an absorption zone.

Abstract: In an agricultural machine (1) with a swivelling supporting arm (3) which is provided with a soil cultivating tool (5) and with a feeler (11) and on which there acts an adjusting piston (16) of a lifting cylinder (15), pressure medium can be fed to the latter in a controlled manner by means of a control device (31). The control device (31) consists of a 4/3-way valve (38) inserted into the pressure-medium feedlines (41, 42) and of switching elements (46, 47) which can be influenced by the feeler (11) and the supporting arm (3). To allow mechanical actuation of the adjusting member (39) of the directional control valve (38) from one side as a function of the respective swivelling movement of the feeler (11) upon swivelling in, the feeler is connected positively to the adjusting member (39) via a Bowden cable (51), such that the adjusting member can be adjusted in proportion to the respective adjustment path of the feeler (11). By virtue of this configuration, it is possible not only to control the swivelling movement of the supporting arm (3) exactly and hold it continuously in a defined position, but high mechanical stresses on the swivelling arm are also reliably avoided since the directional control valve (38) is opened slowly as a function of the swivelling movement of the feeler (11) and the pressure in the lifting cylinder is thus built up continuously. <IMAGE>

Abstract: The invention relates to a process for manufacturing von Willebrand factor. This process comprises the selective adsorption of factor VIIIc on the gel of a first ion exchange chromatography column, the von Willebrand factor being contained in the non-retained fraction, and is characterised in that the non-retained fraction is treated so as to adsorb the von Willebrand factor selectively on the gel of a second chromatography column, the factor then being desorbed and being obtained with a very high purity. The invention enables a von Willebrand factor of very high purity, largely devoid of antihaemophilic factor VIIIc and of inactivators such as Tween and TNBP, as well as of the main plasm contaminants, to be obtained.

Abstract: The barrier consists of a series of light weight modules, filled of a conventional material as ballast to give them stability and resistance. The modules are noticeably rectangular prismatic bodies with top apertures (4) which act as loading nozzles for the filling material, and with lower transversal canals for the circulation of water. One type of module is male and the other female, and to form the barrier they are placed alternatively the ones on the others on the wearing course of the road. The modules can be dismantled to leave an open way in the barrier; they can be articulated or even rigid between themselves and anchored to the ground. <IMAGE>

Abstract: An analog-to-digital converter employs a capacitor circuit for integrating a sample of an input signal during a predetermined interval of time and, thereafter, the capacitor is discharged at a predetermined rate until the integration voltage is equal to that of a reference. The discharge time serves as a measure of the amplitude of the input signal. A measurement interval is established which is equal to an integral number of cycles of each of the possible values of frequency of the A.C. excitation. The signal integration interval has a duration less than or approximately equal to the shortest period of the A.C. excitation, this being the period of the highest frequency A.C. excitation. The signal integration is repeated periodically at each third half-cycle of the highest frequency excitation so that the total integration time experienced during positive half cycles is equal to that experienced during negative half cycles of any of the plurality of excitation frequencies. This cancels the effect of noise due to signal polarity.

Abstract: Improved autoranging, calibration, and complex signal detection circuits for an intermediate frequency (IF) stage in a radio frequency (RF) measurement receiver. An improved autoranging circuit sets a gain stage of a selectively variable gain amplifier prior to each data acquisition cycle, to provide for wide dynamic range and rapid time domain response. An improved complex signal detection circuit for generating an inphase (I) and quadrature phase (Q) signal from an input IF signal in a signal channel and a reference channel is constructed with a novel commutating demodulator circuit. Calibration is effected with an improved digital phase reference method and apparatus wherein effectivr 90 DEG  phase shifts are digitially generated by shifting the generation sequence of timing signals for the complex signal detection circuit instead of phase shifting a known calibration signal, obviating the need for precision phase shifters, Doppler frequency generators, or Fourier transforms to obtain correction components for the optimum detection of complex signals.
