Abstract: A toothed gearing, which is suitable in particular for driving the two spiral shafts of a twin-screw extruder, possesses a drive wheel 1, two intermediate wheels 3, 4 on the drive side, two intermediate wheels 3', 4' on the take-off side, and a power take-off wheel 2. The intermediate wheels 3, 4 on the drive side engage with the drive wheel 1, whereas the intermediate wheels 3', 4' on the take-off side engage with the power take-off wheel 2. Two intermediate wheels 3, 4', which do not engage with each other, are mounted in a frame 5 which is freely movable in the gearing housing, whereas all other wheels are fixedly mounted in the gearing housing. By means of the gearing according to the invention, a substantial equalization of load is automatically achieved in the distribution of the torque to be transmitted to the power take-off wheel 2. <IMAGE>

Abstract: In order to increase the flow rates through drainage materials having a bi-planar mesh structure drainage core 1 and a filter material against one face and a filter material or impervious member against the other face, the drainage core 1 has generally parallel main strands 2 interconnected by generally parallel subsidiary strands 3. The main strands 2 are at least twice as tall as the subsidiary strands 3. The outer faces of the subsidiary strands 3 are coplanar with, and form, one face of the drainage core 1. The ratio of the free cross-sectional area of each main flow channel to the free cross-sectional area of each subsidiary flow channel, if any, is at least 2.5:1. This forms a high compression resistant, high flow, drainage core which exhibits a flow fall-off of not more than 20% under an external pressure normal to the faces of 400 kPa, and turbulence within the drainage core is substantially decreased.

Abstract: A microprocessor control determines, in the course of initiating a heating cycle, whether the blower is operating in the continuous mode, and if it is, the control prompts the blower to be turned off prior to the ignitor being turned on. In this way, the blower and ignitor are never on at the same time and the instantaneous total current draw is limited to thereby reduce the occurrence of burned out fuses or circuit breaker trips.

Abstract: On peut produire, tout en utilisant des procédés de fabrication conventionnels, des corps poreux frittés faits de poudre compacte et ayant la forme de cylindres droits, qui présentent de très faibles variations de résistance à la circulation de liquides. L'invention prévoit de produire de tels corps en série, de sorte que, pour un fluide donné et pour une chute de pression donnée en amont du corps, on peut pré-établir un débit que l'on peut aisément réguler au moyen d'un dispositif simple de régulation de pression permettant de contrôler la chute de pression. L'appareil comprend un tube muni de dispositifs régulateurs de pression, un récipient pour le corps tel que décrit dans l'invention, et une série de corps qui présentant des résistances à la circulation différentes, permettant ainsi de fixer des écarts de débit différents dans le tube pour des fluides donnés. On décrit également un procédé permettant de fixer un débit précis, pour un fluide donné à une pression donnée, et l'utilisation de corps poreux bien définis permettant de fixer la pression désirée en régulant la chute de pression dans le corps.
