Abstract: The application discloses a con-tinuous flow steam condensate removal device for use in a steam condensate removal system of a type which in-cludes a steam condensate line, a Y-strainer for removing debris from the steam condensate line, and a condensate return line. The condensate removal de-vice is an elongated unitary one-piece body (2) having an entrance end (5), an entrance passageway (6), an exit passageway ate passageway (7), an exit passageway (8), and an exit end (9). The inter-mediate passageway includes a cylindri-cal venturi tube (10), which is adjacent an exit of the entrance passageway (6), and a downstream cylindrical discharge-transition passageway (11), which is ad-jacent an exit of the venturi tube (10). The downstream cylindrical discharge-transition passageway (11) has a diameter larger than a diameter of the venturi tube (10) and a length larger than a length of the venturi tube (10). A ratio of the length to the diameter of the downstream cylindrical discharge-transition passageway (11) is greater than five, in order to provide an efficient flow of condensate through the device. A ratio of the length of the downstream cylindrical discharge-transition passageway (11) to the length of the venturi tube (10) may be greater than five.

Title: Hydraulic actuator
Inventor: ROWE ALEXANDER WILLIAM
IPC: F01B11/00
Filed: 1996-11-27
Granted: 2004-11-02
Abstract: A hydraulic actuator has a housing, a drive chamber in the housing, a fluid inlet into the chamber, and a piston reciprocable in the chamber. The piston has diametrical steps Exposed to fluid under pressure to cycle the piston. A sleeve is spaced from and positioned around the piston to define a return chamber. The housing has first and second seats. The first seat and a first surface of the sleeve define an exhaust valve, which has an exhaust port, for the return chamber. The exhaust port is opened and closed by reciprocating the sleeve. The second seat and a second surface of the sleeve define an inlet valve for the return chamber. Reciprocating the sleeve opens and closes the return chamber to the drive chamber. The piston and the sleeve are configured so that they interact hydraulically during cycling to generate hydraulic pressure changes in the return chamber.

Abstract: L'invention porte sur un procédé de pliage de piles de feuilles pouvant comporter soit une feuille soit plusieurs, lesdites feuilles étant éventuellement caractérisées par différents coefficients de résistance au pliage. Le procédé en question assure, au moyen d'une alimentation cyclique séquentielle, où alternent phases de mouvement et pauses, le transport de piles de feuilles à l'installation de pliage. Il consiste notamment à déterminer, pour une pile de feuilles donnée, la résistance au pliage sur la base au moins du nombre de feuilles constituant la pile et/ou de la résistance au pliage de l'une de ces feuilles. La pile en question est ensuite pliée, la vitesse de la plieuse étant régulée pendant la pause normale intervenant dans l'alimentation cyclique. Lorsque survient une réduction de la vitesse de pliage, on rallonge l'interruption de mouvement pour le pliage de la pile suivante si on ne parvient pas à réduire la vitesse de pliage pendant la phase normale de mouvement de l'alimentation cyclique. Inversement, en cas d'augmentation de la vitesse de pliage, selon ce que le temps exige, soit on rallonge l'interruption de mouvement pour le pliage de la pile suivante si on ne parvient pas a augmenter la vitesse de pliage pendant la pause normale de l'alimentation cyclique, soit on ne la rallonge pas, même si l'on ne parvient pas à obtenir l'accélération nécessaire de l'opération de pliage pendant l'interruption normale du mouvement.
