Abstract: The disclosure relates to railway switch mechanism comprising a first switch blade and/or first switch frog rail segment that is vertically displaceable by means of a first displacement mechanism in order to establish a vertical switch movement of the first switch blade and/or first switch frog rail segment between an upper and lower switch state; and a second switch blade and/or second switch frog rail segment that is vertically displaceable by means of a second displacement mechanism in order to establish a vertical switch movement of the second switch blade and/or second switch frog rail segment between an upper and lower switch state. The disclosure also relates to a corresponding method for operating such a railway switch mechanism.

Abstract: A railway switch mechanism including first and second switch blades, wherein a switch point of each of the first and the second switch blades is vertically displaceable by means of a displacement mechanism in order to establish a switch movement in the respective switch point, wherein the respective displacement mechanism includes at least one pair of cooperating wedges having a lower wedge and an upper wedge, wherein at least one wedge of the at least one pair of cooperating wedges is arranged to be displaced in a direction substantially parallel to a longitudinal direction of the switch blade or parallel with a longitudinal direction of the switch mechanism, and wherein the switch blades are elastically deformable in the vertical direction or pivotally connected by hinged joints to first and second closure rails respectively for enabling the vertical displacement of the switch blades.

Abstract: The present invention relates to a support structure and a method for assembling a support structure in a turbine or compressor engine for rotatably supporting a rotor member in a stator member. The support structure includes an inner ring, an outer ring and a plurality of struts which extend radially between the inner ring and the outer ring. The inner ring has integrated portions projecting in the direction of the struts and forming end connections for the struts. The integrated end connecting portions of the inner ring are together with the ring made by a metal alloy having initially oversized cross sectional dimensions relative to the cross sectional dimensions of corresponding strut, followed by working at least one lateral surface for removing material. The purpose is to achieve final dimensions and position to conform to the cross sectional dimensions and correct position of each corresponding strut.

Abstract: The invention relates to a clinching press comprising a press tool (52) and a prebending unit (1) to produce a reciprocating movement in a tool holder (14) of a prebending tool (12), said tool holder being articulated to a foundation (2). The prebending unit (1) has a pressure rod (50) coupled to the press tool (52) and a knee-joint mechanism (28, 30), joined, on the one hand, to a pivot point (36) on the tool holder (14) and, on the other hand, to a fixed pivot point (34) on the foundation (2). The pressure roller (46) is freely rotatably mounted at the connecting point (32) of the links (28, 30). The knee-joint mechanism (28, 30) has a gas pressure spring (38, 42) for returning the mechanism to the starting position shown.

Abstract: A centrifugal separator comprises a rotor having two separate coaxial rotor parts, means for axially interlocking these parts, and means arranged for discharging liquid from the separation chamber of the rotor so that the liquid pressure in the separation chamber varies. The separator is specifically characterized in that one of the rotor parts comprises two separate coaxial walls, an inner wall and an outer wall, that the inner wall is supported axially against the other rotor part, that the axially interlocking means connects the outer wall with the other rotor part, that a space is formed between the two walls, and that means are arranged to provide a force of substantially constant magnitude in the space between the walls during operation of the separator, which force acts to axially separate the walls.
