Granted: 1990-04-18
Abstract: Une soupape à double usage destinée à être utilisée dans des tubages de puits possède un coprs (12) supportant un siège de soupape (18), un élément de soupape mobile (24) pouvant être déplacé axialement jusqu'à un guide (22) et possédant un moyen de fermeture (28) conçu pour venir, dans une position, en contact hermétique avec le siège (18) de manière à empêcher le reflux. La soupape définit le passage pour l'écoulement du fluide de section transversla suffisante de sorte qu'elle peut servir de soupape automatique de remplissage pour permettre au fluide de forage du puits de couler dans une colonne de tubage. Un organe de verrouillage libérable (32) est inséré ou conçu pour insertion dans le corps de soupape dans une position de verrouillage, dans laquelle ledit organe de verrouillage vient en contact avec l'élément (24) de soupape pour empêcher le déplacement de ce dernier en direction du siège de soupape afin de convertir la soupape, sur le site, d'un mode de fonctionnement empêchant le reflux en un mode de fonctionnement permettant le remplissage automatique. L'organe de verrouillage est constitué de sorte que, lorsqu'il est libéré, il s'écarte de l'élément de soupape ou se rétracte pour libérer ce dernier. Il comprend de préférence une pluralité de segments (34).

Granted: 1993-01-20
Abstract: A lead-sealable housing, especially for use as a variable peripheral unit, for example equipped as a printer, data memory module with or without a control keyboard (38), for connection to a taxi meter, is described. The housing is composed of a housing top part (1) and of a housing bottom part (2) which serve for receiving the electronic units and which are protected by means of lead-sealable screws (3, 4). Because a paper storage shaft (11) is formed integrally in the housing top part (1), access to the electronic units remains closed. A combination of lids (12, 16) firmly connectable to the housing top part (1) or of a cover (19) and/or of a cover plate (40) makes it possible to obtain a universal modification of the equipment housing designs. <IMAGE>

Abstract: An amplifier circuit equipped with an input stage (10), a voltage amplifier stage (20) connected to the input stage (10), and a SEPP output stage (30) having first and second control terminals respectively connected to first and second relay output terminals (I1, I2) of the voltage amplifier stage (20), wherein a constant-current bias circuit (40) is connected across the first and the second relay output terminals (I1, I2) in order to prevent output-stage transistors (31-34) from being turned off, thereby decreasing the distortion factor. According to a first embodiment for solving the difficulty in adjusting the constant-current bias circuit (40), said circuit (40) is connected in parallel with a constant-voltage bias circuit having an internal resistance greater than that of the conventional circuit so that most of the bias current will flow therethrough instead of flowing through the conventional constant-voltage bias circuit. According to a second embodiment, use is made of a feedback-type constant-current bias circuit whose current value can be controlled by voltage, and the control voltage is found out from a mean voltage that generates across terminals of the emitter resistors (36, 37) of the output-stage transistors.

Granted: 1993-05-19
Abstract: In a mowing apparatus for three-point linkage, a strut (13) of variable length is inserted between a supporting frame (1) and an intermediate carrier (2). Its function is to limit the vertical movability of the intermediate carrier (2) in the upward and downward direction and, with the support frame (1) in the raised position, to form together with the supporting frame (1) and intermediate carrier (2) an articulated triangle which absorbs the vertical load arising from the inertia force of the inner part of the mowing bar (4) whilst the load rising from the inertia force of the outer part of the mowing bar (4) is transmitted in a strictly defined manner to the supporting frame (1) by means of a tension connection (9, 10). The effect of the strut (13) also prevents a buckling of the rotary axle (3) between the intermediate carrier (2) and mowing bar (4). <IMAGE>

Abstract: The coalescing plate (10) is designed to separate immiscible components of differing densities mixed in a fluid. The plate includes bidirectional corrugations forming crests and valleys. Bleed holes (16, 18) are provided in the crests and valleys to allow the immiscible components to pass through. Plural plates are stacked and separated by spacers (20). The spacers (20) are configurated to provide multiple spacing between adjacent plates.

Solids and other components denser than the host fluid move downwardly and pass through the bleed holes (18) in the valleys. The plates are readily cleaned in situ by passing a nozzle (42) through the bleed holes and introducing a cleaning fluid to flush out the space between the plates.

Title: Electrohydraulic or like pneumatic actuator
IPC: F15B13/043
Filed: 1989-10-04
Granted: 1991-05-08
Abstract: The actuator has a moving spool in a valve body for controlling the pressure medium inflow to and from an actuating cylinder. The pressure medium in the valve body is conducted to each end of the spool in order to use the pressure medium to move the spool when desired. A pair of piezo-electric or magnetostrictive servomotors are provided to actuate on/off valves, each of which controls a flow of pressure medium from each end of the spool. Upon actuation of a servomotor, a valve is opened so that the pressure at the corresponding end of the spool decreases causing a shift of the spool in that direction. The servomotors are triggered by brief electrical digital signals.
