摘要:
The present invention concerns a device for the ventricular emergency support, comprising: a first flexible catheter (2), with a variable transversal section, provided with an extremal balloon (7) for the controlled occlusion of the ascending aorta (AA) of the treated patient; a first pump (12), associated to said first catheter (2) for the aspiration and contemporary input of equivalent blood quantifies into the blood circle of the treated patient; a second flexible catheter (32), with a fixed transversal section, provided with a couple of extremal balloons (34), spaced apart, for the controlled occlusion of the inferior vena cava (CA) and of the superior vena cava (CD) of the treated patient; a second pump (35), associated to said first and second catheter (2, 32) for inflating and deflating said extremal balloons (7, 34) of said first and second catheter (2, 32); an electronic control unit (36) for adjusting and controlling the operational parameters of said first and second pump (12, 35), and for the detection of the cardiac parameters of the treated patient; rechargeable or network means (37, 38) for the power supply of above mentioned components.

摘要:
Disclosed is a knitting machine comprising knitting needles, at least one weft bar (8) for laying at least one weft thread (10) across the knitting needles, an electrically driven thread feeder (14, 22) for the weft thread, a take-down device (28) for the textile material (26), and an electronic device (36) for controlling the knitting machine based on a pattern program for the textile material (26) that is to be produced. In order to improve the production process and the textile material, said control device (36) is provided with control means for adjusting the feeding length of the weft thread (10, 24) that is to be delivered according to the traveling distance of the weft bar (8), which is predefined by the pattern program.
摘要:
In a textile machine, a device for controlling the transverse movement of a thread, such as a warp thread in a weaving machine, comprises a dragging element (2) for dragging a thread (4) moving in a transverse direction, whereby said dragging element (2) is attached on both sides to a frame (10) by means of springs (6,8). The device forms a system that oscillates freely at its natural frequency. Arresting devices (12,14) can adjustably and temporarily hold the dragging element in the extreme positions.
