Abstract: A receptacle has a wall defining a receptacle interior and a shaft housing for guiding a shaft through the wall into the receptacle interior. The shaft housing defines an annular cap with spaced apart inner and outer walls connected by an inner end face facing the receptacle interior. A shaft guide part has an end facing the receptacle interior and an outer surface that defines a gap relative to the inner wall of the shaft housing. The shaft guide part has an annular wall spaced apart from and parallel to its outer surface. The annular wall extends over the free end of the inner wall of the shaft housing and is sealed to the inner and outer walls of the shaft housing by at least one seal each. The shaft guide part is mounted in the shaft housing by a radial ball bearing and by an axial ball bearing.

Abstract: A transport device for a container has a base, a vertical member extending up from the base and a complementary handling unit extending from an end of the vertical member spaced from the base. The complementary handling unit is configured for releasably engaging a container, such as a bioreactor container, so that the container can be transported to a holding device.

Abstract: One aspect relates to a container for inserting into a holding device, comprising: a wall that is flexible at least in some areas, which wall is squashed, at least in some areas, in a transport condition in a direction opposite to a stretching direction; a handling unit connected to the wall, which is designed to come into engagement with a complementary handling unit of a transport device; a securing unit which in a transport condition hinders stretching of the wall of the bioreactor container along the stretching direction, wherein the container can, when the securing unit is released, be extended at least in some areas along the stretching direction, as well as a transport device, a use and a method.

Abstract: The invention concerns a process and an apparatus for manufacturing soldering rods with a copper percentage of at least 60 weight-%. An extruder serves to convert a block of the alloy at a temperature between 540.degree. and 680.degree. C. into an individual wire of a maximum diameter of 10 mm. Upon emerging from the extruder, the wire is chilled to a temperature below 250.degree. C. and either intermediately stored or directly further processed. Immediately following a conductive heating to temperature between 200.degree. and 280.degree. C., the wire is fed to a multi-stage reducing mill where it is reduced by rolling in each stage by a maximum of 25% until it has reached its final cross section.

Abstract: A spiral pipe cleaner including coil sections defined by turns and interspaces is rotatable about its axis by means of a drive machine to thread it through a guide housing 1 with an inlet opening 9 and an outlet opening 10. Several engaging jaws 18, 19, 20 in the housing are received in the interspaces between the individual coil turns, which jaws are distributed on the circumference of the coil axis and axially offset. In order to permit passing coil sections joined by means of couplings, the axial distance of two successive engaging jaws 18, 20 and 20, 19 is larger than half of the distance between the ends of two adjacent coil sections joined by coupling elements. Preferably, the axial distance of two successive engaging jaws 18, 19, 20 is larger than the distance between coil sections. In the preferred embodiment at least one engaging jaw 20 is aligned centrally between two engaging jaws 18, 19 disposed on the other side of the coil axis.
