Date Jun. 24, 1993.A flow meter includes a rotor housing having an inlet, an outlet, and a bore extending axially through the housing from the inlet to the outlet, and a screw spindle arrangement including at least two rotary helical worm bodies which are disposed in the bore and which engage in a form fit manner within one another. A pulse generator is mounted on one of the worm bodies and triggers electrical pulses in the mating measuring transducer which are dependent upon the rotational speed of the worm body. The measuring transducer has a pulse-adjusting and pulse-shaping stage which adjusts the magnitude and/or frequency of the pulses relative to a volumetric flow rate of fuel to the bore. An electric counting mechanism receives the electric pulses from the pulse-adjusting and pulse-shaping stage and typically transmits these pulses to a display unit for display.

Abstract: Dans les machines de filage à fibre libérée, il est nécessaire d'avoir un dispositif comportant un entraînement et un palier pour des rotors sans arbre de filage (1), tournant très vite, qui ait de faibles pertes et qui entraîne et soutienne de manière fiable différents rotors de filage. La structure et le montage du dispositif doivent être peu coûteux. Un tel dispositif muni d'un moteur à champ axial dont le rotor est fixé au rotor de filage et dont le stator (2) est fixé dans le boîtier palier monobloc de stator (4), est d'un montage simple, précis et compact. Le boîtier monobloc du stator (4) comprend, en plus du boîtier du coussinet à gaz-magnétique combiné (35), les autres éléments du dispositif pour lesquels il forme un boîtier commun sur lequel des supports (9) sont également façonnés afin d'assurer la suspension élastique (10, 11) du stator. L'intégration des parties du dispositif dans un boîtier de stator en diminue non seulement le coût de fabrication, mais évite également l'imprécision due aux écarts dans l'assemblage des pièces détachées ainsi que le temps passé à les coller. Un système à gaz à deux circuits (14, 37) pour le palier (35) peut améliorer l'adaptation aux différentes conditions de fonctionnement et augmenter la sécurité de fonctionnement. Ce dispositif permet de régler la position de l'axe de rotation du rotor de filage à fibre libérée par rapport à l'axe de la base d'extraction de manière que les deux axes soient alignés.

Abstract: An improved printer apparatus (20) includes a print head having a series of point-like radiation sources (30), such as LED's, arranged in a row for exposing a recording medium (11). Enabling logic (43) is provided for determining which of the point-like radiation sources are to be selected for energization. A current driver responsive to the logic provides electrical current to the radiation sources selected. The current driver includes a current mirror having a master circuit (44a) for generating a reference current and a plurality of slave circuits (44b) for providing respective driver currents to the radiation sources selected for energization. The master circuit includes a series of parallel connected transistors (55) that may be instantaneously reprogrammed by digital control signals to said transistors. The characteristics of the transistors vary so that currents from them are scaled by say powers of two to provide an expanded current control capability. Environmental conditions and/or aging often require change in current to maintain desired recording performance. The need for such change may be automatically sensed and a new digital control word sent to the transistors to adjust current to the radiation sources.
