Abstract: A vortex-shedding mass flowmeter which includes a shedding body (12) mounted in a pipe (14) containing a flowing fluid, a first detecting element (18) that responds to the vortices generated when the fluid flows past a surface of the shedding body for producing a velocity signal proportional to the flow rate of the fluid, a second detecting element (28) for sensing in a measuring plane that includes the surface of the shedding body (12) where vortices are generated a moving fluid characteristic dependent on the product of fluid density and the square of the fluid flow rate, and electronic circuitry (36) coupled to the outputs of the first and second detecting elements for producing therefrom a mass flow rate signal. In one preferred embodiment, the second detecting element (28) is a pitot-type head device which senses a pressure differential between static and dynamic pressures existing at two locations on the measuring plane. In another preferred embodiment of the present invention, the second detecting element includes a drag body flow device which responds to the force being applied thereto by the flowing fluid.

Abstract: Un matériel de forage, en paticulier pour des forages en haute mer, comprend une plate-forme de forage (11) avec un derrick (10) ou tour de forage se dressant depuis la plate-forme. Un premier treuil (12) connecté à la partie supérieure du derrick est utlisé pour faire passer une longueur d'un corps tubulaire (19), tel qu'un train de tiges de forage ou un tubage de renforcement du puits, au travers d'une ouverture (18) de forage définie et s'étendant au travers de la plate-forme de forage. La longueur tubulaire est connectée ou détachée du train de tige de forage ou du tubage du puits pendant l'opération de forage, et ces longueurs tubulaires sont stockées dans une zone de stockage (31, 32) sur la plate-forme de forage. Les longueurs tubulaires peuvent être transportées depuis la zone de stockage vers le premier treuil (12) et vice-versa par des premiers moyens de transport (22). La plate-forme (11) de forage définit également une ouverture de préparation (21) s'étendant au travers de la plate-forme et se trouvant à une certaine distance de l'ouverture de forage et de la zone de stockage, et un second treuil ou treuil de préparation (20) est connecté à la partie supérieure du derrick ou tour de forage au-dessus de l'ouverture de préparation. Deux ou plusieurs sections tubulaires peuvent ensuite être assemblées en longueurs tubulaires au niveau de l'ouverture de préparation à l'aide du treuil de préparation tandis que se poursuit l'opération de forage, et les longueurs préparées peuvent être transportées vers la zone de stockage et y être stockées pour être prêtes à être utilisées au niveau de l'ouverture de forage. De même, des longueurs tubulaires peuvent être démontées et réduites en sections tubulaires au niveau de l'ouverture de préparation avant d'être transportées depuis le site de forage. La possibilité d'assembler et de démonter des longueurs tubulaires avec des sections tubulaires au niveau de l'ouverture de préparation pendant que se poursuit l'opération de forage au niveau de l'ouverture de forage réduit sensiblement les temps morts nécessaires dans les opérations de forage.

Granted: 1991-04-24
Abstract: L'objet de la présente invention est de permettre le verrouillage à vitesse et pression élevées d'un moule à l'aide d'un moteur électrique de faible capacité en utilisant un système vis-écrou dans un dispositif de verrouillage, par exemple d'une machine de moulage par injection, afin de réduire l'encombrement global de la machine. L'invention se caractérise par l'utilisation d'un système vis-écrou constitué de deux vis disposées en série sur l'arbre rotatif et de deux écrous en prise avec les vis, l'un des écrous étant fixé sur un châssis stationnaire ou sur un plateau mobile et l'autre écrou étant monté par l'intermédiaire d'un embrayage. Lorsque l'embrayage est en prise sur le châssis stationnaire ou sur le plateau mobile alors que l'arbre est en rotation, les deux écrous et l'arbre rotatif se déplacent l'un par rapport aux autres sur une distance qui est fonction des pas des deux vis, ce qui permet le verrouillage rapide du moule. Lorsque l'embrayage est dégagé, l'arbre rotatif et uniquement l'écrou fixe se déplacent l'un par rapport à l'autre, ce qui permet le verrouillage du moule avec une pression élevée.

Title: Apparatus for reversing and adjusting the cutting width of a reversible plough
IPC: A01B3/421
Filed: 1987-09-09
Granted: 1991-08-28
Abstract: The apparatus serves for reversing and for adjusting the working width of reversible ploughs and has a double-acting hydraulic reversing cylinder 5 and a setting cylinder 15 which, for adjusting the working width, is assigned a chamber 26 of variable volume, and with a hydraulic circuit, by means of which, during reversal, first the setting cylinder 15 is brought to the minimum working width and only thereafter is the reversing cylinder actuated, the set working width being stored by means of a specific volume of hydraulic fluid in the chamber 26. For this, there is a further cylinder 25 which is separated by the piston 27 and of which the first cylinder space 26 forms the chamber, the hydraulic circuit 20 feeding the fluid displaced from the setting cylinder 15, before reversal adjusting the working minimum width, to the chamber of the further cylinder 25. For this, the second cylinder space 32 is connected via a first direct line 13, at the start of reversal and before the automatic interchange, to the line 6 of the reversing cylinder 5 leading to the tank and, thereafter, to the line 7 of the reversing cylinder 5 leading to the pump, and the hydraulic fluid displaced into the first cylinder space 26 of the further cylinder 25 is discharged. Subsequently, the second cylinder space 32 connected to the inflow line 6 of the reversing cylinder 5 via the direct line is subjected to fluid, so that the piston 27 resumes its specific initial position, with the set working width being restored. <IMAGE>

Abstract: The control device can be activated by means of opening and closing signals, but it ensures an independent control of the opening and closing movements of the door. With an opening signal present, during the actuation of a door handle the door is opened for a predetermined period of time. With a closing signal present, a closed door is locked, an open unused door is closed and locked, and an open used door is kept open for a predetermined period of time and then a closing operation is initiated. If the door is used during a closing operation this is at all events maintained for a predetermined period of time, then reversal occurs for a further period of time, subsequently a neutral holding of the door takes place for a further period of time, and then a new closing operation occurs. With a closing signal present, only a preadjustable number of reversing operations is possible, and subsequently the closing operation proceeds uninterruptably. The control device thus ensures that, after the closing signal has occurred, the door at all events closes within a specific period of time, and it is not possible to keep it open by a constant actuation of the reversing device. <IMAGE>
