Abstract: A disc brake arrangement, especially for heavy duty applications in which a pair of brake arms having brake members on the sides facing each other are pivotally supported at one end and spring biased toward each other at the other end. The brake members are adapted to receive the periphery of a brake disc therebetween. A disengaging device is provided which includes a lever pivoted to the free ends of the arms and having a wedge shaped nose which will press the arms apart when the lever is pivoted in one direction and which will cam out between the arms when the lever is released. The brake members are adjustably mounted on the respective arms and each brake member support includes an adjustment, with each adjustment being provided with a free wheeling one way clutch device.

Abstract: A device for moving long and thin bodies into narrow spaces by means of a gripper which is adapted to be lifted and lowered and on which the long thin bodies are suspended. This device, which is particularly well suited for control bars, shut-off bars, and the like of core reactors, is characterized primarily in that for laterally supporting the lower ends of the long thin bodies when the latter by means of the gripper have been pulled out from the respective narrow spaces in which they were previously received, at least one gripper means is so arranged at the lower end of a holder vertically slidably guided on the supporting member for the gripper means that the gripper means can be brought into and out of engagement with the lower ends of the long thin bodies.
