Patent EP-0219766-B1 (EP)
IPC: B01D11/04
Filed: 1986-10-08
Granted: 1990-02-28
Abstract: With the extraction method, a material exchange column with an ordered packing 2a or 2b on the basis of a plurality of layers 3 stacked parallel to the column axis and making point contact with one another is used. The packing 2a, 2b is perfused by a continuous and a dispersed phase in a counter current. The packing has a very large specific surface area of at least 300 m2/m3 of packing volume. At the periphery of the packing 2a, 2b, the two phase streams are re-circulated into the packing at regular intervals through a rim seal composed of an elastic material not wettable by the dispersed phase. The rim seal is placed round the packing in the form of an elastic tube or pipe and seals the intermediate space between the internal column wall and the packing. A further improvement in the separating capacity can be achieved if pulsating operation is adopted. The method is characterized, in particular, in that an approximately constant high separating capacity is achieved with a high throughput per unit area over a relatively large loading tolerance of the column.

Granted: 1991-03-06
Abstract: In a liquid crystal device one interior surface of the cell is coated with a polymer (e.g., a crystalline polymer such as PET) which, when rubbed, produces alignment of the liquid crystal molecules, and the opposite interior surface is coated with a material (e.g., an amorphus polymer, such as PMMA) which, even if rubbed, does not produce such alignment. Also described is a combination of an aligning polymer and a non-aligning, non-polymer (e.g., a silane surfactant or bare ITO). This technique is particularly useful in producing alignment of relatively thick, ferroelectric smectic liquid crystal cells.

Date Nov. 6, 1986.In particular, there are provided in accordance with the invention a method and apparatus for adjusting a digital equalizing filter in a hybrid circuit in a telecommunication system for transmitting digital information in duplex on a single line pair with simultaneous adaptive echo elimination and adaptive elimination of noise caused by intersymbol interference, where a first and a second compensation signal (e(t), i(t)), which are respectively dependent on the stored parameters of a digital balance filter and an equalizing filter, are subtracted from a received signal (a(t)+e(t)+i(t)) to form a difference signal (r(t)) which is compensated for noise respectively caused by echoes and intersymbol interference, the balance filter parameters being corrected with the aid of a correction signal ( epsilon B kappa ) dependent on the difference signal (r(t)). The equalizing filter parameters are adjusted with the aid of a further correction signal ( epsilon U kappa ) formed by the balance filter correction signal ( epsilon B kappa ) and the first compensation signal (ê(t)) such that the further correction signal ( epsilon U kappa ) will substantially agree with the balance filtercorrection signal ( epsilon B kappa ), but obtain the value zero when the first compensation signal (ê(t)) and the balance filter correction signal ( epsilon B kappa ) are both positive simultaneously or negative simultaneously. There is thus prevented the correction sequence of the equalizing filter parameters when the balance filter parameters are changed in a direction such that the absolute value of the estimated echo (ê(t)) increases.

Abstract: Removal of water from a fibre suspension, in particular cellulose pulp in a static thickner which essentially does not comprise moving parts. The clogging of the perforations in the screen sufaces (14,15,28,30,38,40,74,75,88,90) is reduced by dimensioning these perforations and the flow channels (13,33,37,76,87) in such a way that the pulp flows in the channels (13,33,37,76,87) as a plug flow, that is, the internal friction of the pulp is greater than the surface friction between the pulp and the screen surface (14,15,28,30,38,40,74,75,88,90). The process and apparatus (52,62) may be applied whenever a dilute pulp must be thickened, e.g. during pulp bleaching or refining of rejects.

Abstract: First and second spaced apart optical emitter-receiving pairs are located along a liquid carrying conduit. A regulator circuit is coupled to each emitter-receiver pair to control the operation of that pair inside a maximum response range regardless of the transparency of the liquid. The regulator circuit is so arranged as to supply the emitter with a voltage which is a function of the difference between a voltage supplied by the receiver portion of an optical-receiver pair and a reference voltage. A differential circuit produces a differential signal representing the difference between the signals produced by the receiver portions of the optical emitter-receiver pairs and a comparator circuit is connected to the differential circuit in order to generate an alarm signal as a function of the differential signal. The detector is particularly useful as an air bubble detector in a transfusion or perfusion system, and can also provide a container-empty alarm in such systems.

Granted: 1993-07-28
Abstract: Dispositif à semi-conducteur possédant une fenêtre à travers laquelle pénètrent des rayons ultra-violets et similaires. On a utilisé jusqu'à présent des dispositifs à semi-conducteurs possédant une fenêtre à travers laquelle des rayons ultra-violets peuvent tomber sur une mémoire rémanente à circuit intégré (éléments à semi-conducteur) dans le module à semi-conducteurs de sorte que les données déjà écrites peuvent être effacées pour permettre l'écriture de nouvelles données. La fenêtre d'irradiation peut avoir une forme circulaire ou rectangulaire. Dans le cas d'une fenêtre circulaire, le cercle doit avoir une taille importante de manière à s'adapter à des éléments à semi-conducteurs intégrés à grande échelle. Dans ce cas, toutefois, il se produit une diminution de l'interstice entre la surface latérale dans le sens de la largeur du circuit à semi-conducteur et la fenêtre, ce qui affaiblit le module à semi-conducteur. Lorsque la fenêtre présente une forme rectangulaire, d'autre part, des fissures se développent facilement aux coins des trous traversant du module à semi-conducteurs. Cette invention se caractérise en ce que les bords opposés de la fenêtre sont droits et parallèles dans le sens de la largeur du module à semi-conducteurs, et que les bords opposés sont arqués dans le sens de la longueur du module à semi-conducteurs. Par conséquent, la fenêtre couvre une surface suffisamment étendue et aucune fissure ne se développe dans la fenêtre du module à semi-conducteurs.

Abstract: A fluidic oscillator (20) is relatively short in length (under about 2.5 W where ''W'' is the width of the power nozzle) and has a leaky splitter (22) located proximate the center of the outlet flare (21) so as to divide the outlet into essentially two alternating slug flows. The floor (FW) and/or ceiling (CW) of the oscillator diverge between about six degrees and ten degrees to allow the jet steam to expand and thereby avoid creating a back pressure to control ports (CP1 and CP2). When used as a windshield defrost/defog nozzle, vanes (29L and 29R) forming part of the leaky splitter are laterally shifted so that the largest opening is on the drive side and the smaller opening is on the passenger side so as to direct more defrost energy towards the drivers's side.

Abstract: This invention relates to an improved injection molding nozzle (10) and a method of making it. The nozzle has an electric heating element (66) integrally vacuum cast in copper (68) in spiral channels (70) cut in the outer surface (60) of the tool steel nozzle body. The heating element has a cold terminal (78) at one end which projects out through a hole in a head plate (62) which is rotatable prior to casting to ensure the nozzle has a consistent length of heating element cast in. A sleeve (120) is located over the spiral channel prior to casting to ensure the heating element in the channel is covered with a minimum depth of copper to dissipate the heat from the heating element. The spiral channel can be cut with a varying pitch according to a predetermined profile to provide more heat where there is more heat loss.

Abstract: The recording current necessary for recording a video signal is always to be optimally selected and adjusted with respect to the replay sensitivity, having regard to an audio signal already recorded on the same tracks and having regard to tolerances of the recording medium, of the heads and of the head amplifiers, by means of the novel method. For this purpose, the recording current is changed in steps during the recording of the video signal. After each change in the recording current for the video signal, a direct-voltage value is determined from the replay envelope curve of the audio signal as a measure of the replay amplitude of the audio signal. As soon as the direct-voltage value obtained from the replay envelope curve of the audio signal reaches a predetermined minimum value, the changing of the recording current for the recording of the video signal is ended and the last value of the recording current is stored for the following recording process. Recording systems in which video and audio signals are stored in tape layers of different depth. <IMAGE>

Abstract: In a device for measuring the power of a crank drive in which the torque is transmitted from the crank (1) to a drive disk (2), for example to the face of the bottom bracket ball bearing of a bicycle, the mechanical parameters, torque and angular speed of the crank are converted to electric signals. The force (K) exerted on the crank via a deformation element (3), for example a flexible element, is transmitted to the drive disk (2) and the deformation of the deformation element (3), which is a measure of the force (K), is converted to an electric signal by elongation gauges (6), inductive displacement sensors, or piezoelectric crystals. The angular speed of the crank (1) is measured by a reed contact, a light barrier, an induction loop, or a mechanical tachometer. When this type of power measurement is applied to a bicycle, the pedalling power is not converted to braking heat as in the case of stationary ergometers, but can be converted to forward movement of the bicycle.
