Abstract: The invention discloses a method for sanitization of a bioprocess chro matography column, comprising the steps of: a) providing a bioprocess chromatogra phy column with a packed bed of separation resin particles and a movable adapter, b) with the adapter in contact with the packed bed, conveying a sanitization fluid through the packed bed to a column outlet; c) raising the adapter to provide a gap between the packed bed and the adapter, d) lowering the adapter to close the gap; and e) conveying an equilibration liquid through the packed bed to a column outlet.

Abstract: A device (2) for a body fluid bag, includes a filtering part (5) and a retransfusion part (6), the filtering part (5) having a filtering part inlet opening (7) and a filtering part outlet opening (8). The outlet opening (8) is arranged to be connected to an inlet opening of the body fluid bag, and the retransfusion part (6) has a retransfusion part inlet opening (10), being arranged to be connected to an outlet opening of the body fluid bag, and a retransfusion part outlet opening (11), wherein the filtering part (5) and said retransfusion part (6) are mechanically integrated to form a single unit. A transfusion unit (16) including such a device (2) is also disclosed.

Abstract: Devices are disclosed for locking rotatable fasteners in a construction element including a shaped surface which defines an axis of rotation for the rotatable fastener, and at least one protrusion extending into the shaped surface as a lock for the rotatable fastener, in which the protrusion can be processed with respect to the axis of rotation of the rotatable fastener to create an end surface on the protrusion which is a predetermined distance from the axis of rotation of the rotatable fastener irrespective of the location of the axis of rotation relative to the shaped surface. Methods for producing such devices are also disclosed.

Abstract: A leaf spring for suspension of a rigid axle of a vehicle. The spring is joined at its first and second ends to a frame of a vehicle. The spring has a first portion extending from a first end to the junction with the axle in which the thickness of the spring increases along a parabolic curve from a first starting value at the first end to a first maximum value at the juncture with the axle, and a second portion which has a thickness which increases along a parabolic curve from the same first starting value at the second end to a second maximum value at the junction with the axle, the second maximum value being less than the first maximum value so that the stiffness of the first portion is greater than the stiffness of the second portion to such an extent that the radius of curvature of a path along which the axle is moving during flexing of the spring is increased by at least 5% compared to a corresponding spring having substantially the same first and second maximum values.

Abstract: A leaf spring for the suspension of a rigid wheel axle (10) in an automotive vehicle, is pivotally but not laterally displaceably connected at a first end (15) thereof to the vehicle and is pivotally connected at a second end (16) thereof also to the vehicle. A center part (14) of the spring is connected rigidly to the wheel axle (10). The spring (6) between the first spring-end (15) and the center part (14) of the spring is straight or downwardly concave. The spring (6) between the center part (14) of the spring and the second end (16) of the spring has a double-curve configuration and, seen from the side, has a downwardly convex part (19) located nearest the center part (14) and a downwardly concave part (20) located nearest that second end (16) of the spring and adjoining the downwardly convex part (19).
