Title: Device for improvement of running condition in hydraulic system
Inventor: INGVAST HAKAN
IPC: F15B21/0423
Filed: 1990-11-05
Abstract: The present patent application refers to a device for the improvement of the running conditions in a hydraulic installation or in so-called hydraulic system. The device contains a central circulating circuit separated from the influence of the atmosphere. To the circulating circuit are connected an outlet and an inlet for the connection of the hydraulic fluid to the other parts of the hydraulic system. The mentioned circulating circuit is divided into at least two chambers separated by pressure generating respectively pressure reducing units (3, 4, 5). The first chamber (1) is to a certain extent an expansion room for the hydraulic fluid in the system which is separated from the atmosphere and it forms a low-pressure part in the circuit. The second chamber (2) forms a high-pressure part which directly or indirectly is connected to the said outlet. The circulating circuit holds medium (4, 13) for the cooling and filtering of the hydraulic fluid.

Abstract: The linear shed multiphase loom has a shed forming weaving rotor (11) into which weft threads (9) are inserted. It is fitted with shed forming guide elements (12) and with reeds (15), into which laying elements (31) insert warp threads (1-8, 1'-8') by lateral displacement to the direction of rotation (10). During shed formation, a deflection laterally to the direction of rotation (10) is imparted to the majority of warp threads which is only cancelled when the guide elements (12) dip away before the beat-up, so that the warp thread realign themselves. If this realignment is incomplete and shows systematic deviations, a formation of stripes, i.e. reediness, will occur along adjacent warp threads. According to the invention, the position of laying elements (31), the geometry and position of reeds (15,16,17,28), the position of up and down guides and the laying programme are correlated to each other in such a way that reediness can be controlled for reeds with at least two warp threads per occupied space (25).

Le dispositif de retenue comporte des protubérances (72A) destinées à coopérer avec la fente en ce que ce dispositif doit être pressé pour en refermer les branches et permettre au couvercle d'être coulissé dans la plaque. Une fois dans cette position, les branches sont libérées, ce qui pousse les protubérances (72A) dans les encoches (73) de la fente, les pattes empêchant la séparation de la plaque et de la partie en couvercle à moins que les branches du dispositif de retenue ne soient encore une fois pressées l'une vers l'autre. Lorsque l'ensemble est appliqué au pistolet, l'ensemble peut être verrouillé par le déplacement coulissant de la plaque par rapport à la partie couvercle jusqu'à ce que les épaulements de cames se coincent contre les protubérances, ce qui serre les branches du dispositif de retenue autour du pistolet.

Abstract: A connector for detachably securing an end of a tube, such as a catheter, to a fluid port of a fluid transfer device, such as an implantable device, the connector having a body part which defines a coupler for coupling to a coupler receiver of the transfer device. The connector includes a sleeve which fits within the body part and defines an aperture for compressively receiving an end of the tube which has been fitted over a fluid port of the transfer device. The body part is rotatable about the sleeve to facilitate coupling of the coupler and coupler receiver. In one embodiment the sleeve has an inner diameter at one end large enough to slide freely over the tube when it is fitted over the fluid port, and the diameter decreases at an intermediate point along the length of the sleeve to provide for compressive axial movement of the tube to form an annular thickness portion of the tube where it abuts the face of the transfer device.
