Abstract: Procedure and means for making a vertical drain in the bottom of a water body, e.g. a sea or lake, from a raft on the surface of the water body. A conveying member, carried by the raft movably in vertical direction, is brought to be close to the bottom of the water body. A push tube, carried by the conveying member movably in vertical direction, is pushed into the soil layer on the bottom of the water body to desired depth, whereby the push tube carries along the prefabricated drain, provided with an anchor on its lower end, located therewith in. Thereafter, the push tube is pulled up, the strip drain remaining in its place in the soil layer by the aid of the anchor. The aim of the invention is to reduce the consumption of prefabricated drain material, to reduce the time consumed in the operation and to reduce energy consumption. The invention teaches to pull the push tube up above the lower end of the conveying member. Another anchor is affixed to the prefabricated drain by the aid of an affixing means, located on the lower end of the conveying member.

Abstract: A matrix printer comprises a printing head which includes a plurality of printing needles (11) each having a respective electromagnetic maneuvering device (10) by means of which the needle, carried by a spring-biassed, movable armature (12), can be caused to carry out a working cycle, which includes a working stroke and a subsequent return stroke. The maneuvering device (10) is activated by temporarily lowering the magnetomotive force in the magnetic circuit (12,14) of the device from a previous, constant value. The previously attracted armature (12) will herewith commence to move in a direction away from the stationary part (14) of the magnetic circuit as a result of the spring force acting on the armature. The magnetomotive force is then caused to return to its previous value. For the purpose of reducing the noise and wear generated by the armature (12) and to reduce the tendency of the armature to rebound, the armature is slowed down during the final stage of its return stroke, by again lowering the magnetomotive force temporarily for a limited part of the time taken to effect the return stroke.

Abstract: A respirator comprises a respiratory air circulation unit with an adjustable displacement volume and a respiratory air supply line and a respiratory system comprising an inspiration loop, an expiration loop and valve elements mounted in these loops. The valve elements are controllable by means of a control unit, so that small as well as large displacement volumes can be executed by means of a single circulation unit with the smallest space requirements possible. For this purpose the inspiration phase is divided into several sub-phases, during which the control unit controls the valve elements and the respiratory air circulation unit 4 so that several fillings of the adjustable displacement volume are supplied to the inspiration loop and only then is the expiration phase initiated. Thus the displacement volume of the circulation unit can be kept small. One or a few inspiration sub-phases are sufficient for the artificial respiration of infants and premature infants, while a multitude of sub-phases can be executed for the artificial respiration of adults with a large respiratory volume.
