Abstract: A motor-pump unit for submerging down a well, e.g. an oil well, comprises a motor portion driving a pump portion. The motor portion is filled with fluid to prevent ingress of the surrounding medium which the pump portion pumps. The fluid is maintained at a higher pressure than the surrounding medium by including a flexible tank filled with fluid and in communication with the fluid in the motor portion. The flexible tank is compressed both by the surrounding medium and by resilient compression means so that the pressure inside the motor is higher than the surrounding pressure, thereby ensuring any leakage is outwardly from the motor. Down the well the temperature rises causing the fluid to expand, so the flexible tank is left substantially empty when the unit is prepared at the surface prior to lowering. If a large rise in temperature is to be expected, a resilient compression means which provides adequate excess pressure near the top of the well as the unit is lowered, will provide too much excess pressure at operating depths, and similarly compression means which provide adequate excess pressure at operating depths do not supply enough near the surface. This problem is solved by providing compression means which includes a first spring (79) and a second spring (80) so disposed that the flexible tank (66) is subjected to the sum of their resilient thrusts, with the second spring applying its thrust via release means (83 to 88) which cause said second spring to be released and to relax once its displacement reaches a predetermined value.

Abstract: 1.

Abstract: Method and device for completing the automatical matching of panels to be cut in patterned fabrics to ensure that the design for each one of the panels to be cut is in its correct position. After defining a series of matching points on each of the patterns and recording as digital data in a memory the matching relationships for each one of these points are defined and stored as matching information in the memory, the matching itself is carried out using a TV-camera (12) installed on the cutting machine (11), capturing images from any point of the fabrics being spread in connection with a digital image processing unit which, by processing the images captured, fix the real position of the design on the fabrics. Matching device, integrated marking and a cutting system are connected in such a way to process the image information with the predicted matching relations to generate an adjustment to the position initially assigned to each panel - in both directions and in orientation - and guarantee a perfect cut of the panels.
