Abstract: Sont décrits un procédé et un dispositif filtrant pour la séparation en continu de particules contenues dans un fluide (3) s'écoulant dans une canalisation. Lors de son entrée dans l'appareil, un mouvement rotatif est imprimé au fluide au moyen d'un élément (7) produisant une rotation, ce qui amène le flux de fluide à passer à travers un filtre agencé au niveau de l'extrémité aval de l'appareil. Le filtre comprend une surface filtrante (20.1) et une surface de filtre (20.2), la surface filtrante s'étendant le long de l'axe rotatif du fluide et la surface de filtre étant placée de manière à former une barrière d'aval pour le fluide non filtré. Ainsi, en cas d'augmentation soudaine de la pression dans le fluide, la surface de filtre, pendant une phase initiale, permet le développement d'un puissant mouvement rotatif synchronisé avec la séparation des particules arrachées s'effectuant contre la surface de filtre (20.2). On laisse suffisamment de temps au mouvement rotatif du fluide pour se stabiliser et les particules arrachées sont chassées de la surface filtrante et, par suite du mouvement du liquide, elles sont simultanément déplacées dans le sens longitudinal du dispositif en direction de la surface de filtre.

Abstract: In a traffic guidance system, a vehicle (FZ), when passing a stationary guidance beacon (BK), receives therefrom guidance information items (LK1, LK2, LK3) for all destination points which can be reached from the guidance beacon. For transmitting the guidance information items, all destination points (Z) to which the same guidance information applies, are combined to form in each case one destination area (F1, F2, F3), each destination area being bounded by a polygonal line of any type. The allocation of a selected destination point (Z) in the vehicle is effected by a comparison with the boundary lines (GR1, GR2, GR3) of the destination areas. The destination point (Z) must be allocated in each case to the destination area (F3), with the boundary line of which a coordinate system placed through the destination point exhibits an odd number of points of intersection in each direction of the compass. <IMAGE>

Abstract: A speech coding and decoding apparatus used for linear predictive coding of a speech signal and for transmitting it in a digital signal. In coding operation, a linear predic­tive residual signal is extracted from an input speech signal subjected to linear predictive analysis. The strength of the correlativity between the pitch periods of the waveform of the extracted linear predictive residual signal is obtained for every plural blocks. The time axis of the linear predictive residual signal for every two adjacent pitch period sections for the block in which the strength of correlativity of the waveform is not less than a predetermined threshold value and is larger than that of another block is compressed into a residual signal for one pitch period section repeatedly. Quantization allotting bits are preferentially allotted to the portion of the linear predictive residual signal subjected to time-axis compression, and the quantized signal is transmitted. In decoding operation, the partially compressed and quantized linear predictive residual signal is separated from the transmitted signal, and the separated linear predictive residual signal is inversely quantized. The partially compressed portion of the inversely quantized linear predictive residual signal for every one pitch period section is partially expanded to the residual signal for two pitch period sections repeatedly so as to restore the   reproduced residual signal which has the same length of original residual signal. The time axis of the linear predictive residual signal is compressed and expanded only at the portion which has a large waveform correlative strength, thereby ensuring good synthesized speech quality. And time-axis of linear predictive residual signal is compressed and expanded within analysis frame, thereby enhancing the proof to transmission error.

Abstract: A bowl-feed apparatus is described in which a gas flow is used to drive workpieces (3) through tooling (5) designed to segregate and orientate them. The tooling (5) is optionally interchangeable, and depends on the workpieces (3) being fed through the system. Workpieces (3) are initially supplied to a rotating disc (8) at the centre of the bowl, the rotation forcing them onto a feedtrack (4) at the disc perimeter. Gas is fed onto the feedtrack (4) through slots, angled such that gas propels the workpieces (3) along the feedtrack (4) and through the bowl tooling (5). The track is segmented, each segments being associated with its own gas inlet and regulator (21). In this way the flow characteristics, and hence the velocity of the workpieces (3), can be varied in each of the track segments. By having a completely controllable feed rate and the ability to exchange the tooling (5) within the bowl, the same bowl can be used to feed a multitude of different workpieces (3). The ease of "fine-tuning" the bowl for different workpieces (3) and tooling (5) greatly reduces the number of stoppages due to workpieces jamming the system.
