Abstract: Un caloduc (10) comprend une enceinte (20) tubulaire étanche allongée définissant une cavité (50) de travail fermée dans laquelle de l'eau sert de liquide de travail. L'enceinte (20) est formée d'une matière réagissant avec l'eau pour produire de l'hydrogène à l'état gazeux. Un moyen d'oxydation (30) est diposé dans la cavité de travail (50) dans la partie du condenseur (25) du caloduc (10). Ledit moyen d'oxydation (20) comprend une substance réagissant avec l'hydrogène produit pendant le fonctionnement du caloduc afin d'oxyder ledit hydrogène dans de l'eau. Les substances convenant comprennent des oxydes métalliques tels que CuO, PhO2, MnO2 et HgO, présentant un potentiel d'électrode (ou un potentiel de réduction) supérieur à celui de l'hydrogène, c'est à dire que le potentiel d'électrode (ou potentiel de réduction) doit être un potentiel positif par rapport au potentiel d'électrode zéro de l'hydrogène.

Abstract: A method and apparatus for pressure control of an electrically powered injection molding machine capable of smoothly controlling the pressure stepwisely without mounting any particular servomotor on the injection molding machine or without replacing a servomotor once mounted by another servomotor. At the time of transfer from an injection step to a first pressure-maintaining stage and at the time of transfer from the pressure-maintaining stage to a next pressure-maintaining stage, the CPU for numerical control calculates a correction quantity (S7) by dividing a value obtained by subtracting a maximum injection pressure or a torque limit value in the pressure-maintaining stage before transfer from a torque limit value in the pressure-maintaining stage after the transfer, by a required number of times of correction that is obtained by dividing a predetermined switching time in the pressure-maintaining stage after the transfer by a period for executing the pressure-maintaining control operation. Then, the correction quantity is added for every period to gradually renew (S8) from the maximum injection pressure or the torque limit value in the pressure-maintaining stage before transfer up to the torque limit value in the pressure-maintaining stage after the transfer. The maintained pressure practically applied to the screw from the injection servomotor controlled by the servo control CPU varies favorably following the torque limit value that is gradually renewed, and whereby the multi-step pressure control is smoothly carried out.

Abstract: The invention comprises the use of a memory (MCT) in which to each virtual cell-routing circuit is allocated a location containing a context (CT), defining the conditions for evaluating the bit rate of this virtual circuit and provides, upon the reception of each cell, for the reading of the context of the virtual circuit to which this cell belongs, with a view to evaluating the bit rate of this virtual circuit. The invention further comprises the use of a clock (BC) set aside in order to supply a current time associated with this virtual circuit. 
<??>A start time indicator is recorded in the context (CT) of a virtual circuit and, upon the arrival of a cell of this virtual circuit, the context is read, from the current time, supplied at that moment by the clock, is subtracted the start time supplied by the context read, and the time difference thus established constitutes a measurement of instantaneous bit rate of the virtual circuit, defined as the time interval which has elapsed between two cells, this measurement of instantaneous bit rate being supplied to evaluation means (BT), whereas the current time is then recorded in the context, in the guise of start time.

Abstract: On utilise pour mesurer les irrégularités de fonctionnement de moteurs à combustion interne l'équation suivante: LUW = f(T) x |(T_V2 - T_V1) - (T_V3 - T_V2)|, où T_V1, T_V2 et T_V3 représentent les durées de combustion mesurées entre deux marques d'identification de segments fixes. On obtient ainsi différents groupes de valeurs correspondant à des irrégularités de fonctionnement, et l'on applique successivement cette équation à des durées de combustion correspondant à différentes combinaisons de cylindres. On fait pour chacun de ces groupes la moyenne des valeurs correspondant aux irrégularités de fonctionnement et l'on calcule la différence entre le minimum et le maximum des valeurs moyennes. Cette différence sert alors à déterminer l'ampleur de l'irrégularité de fonctionnement.

Abstract: In this bogie (1) the static and dynamic forces are absorbed by the frame (5). In designing the body unit fitted on the frame (5), therefore, only the unit's own weight and the passenger load are significant, thus facilitating the use of extremely lightly-built vehicle bodies. The bogie (1) consists of single-wheel drive units (2), a longeron (3) interconnecting them, on each long side of a drive (4), the frames (5) bearing the end unit (9) and a drive control (6) for turning the single-wheel drive units (2) horizontally depending on the curves. A wheelless central unit (10) is supported on each short side on the bogie (1) via a joint (8). A ush-pull device (7) engages with the short side opposite the joint (8). There are no lobbies inside the vehicle which is thus freely accessible. In the region of bogie there are recesses in the form of wheel-boxes in which certain parts of the bogie (1) are arranged.
