Abstract: A plug valve comprises a plug (10) rotatable in a body (16) of plastics. The plug (10) fits closely within a thin walled metal can (30). The valve body (16) is formed by moulding around the can (30) and plug (14), the can (30) thereafter remaining fixed within the valve body, while the plug (14) is rotatable in the can (30). Seals (22) which are also embedded in the valve body during moulding project through the fluid passage openings in the can to engage the surface of the plug. The provision of the can (30) prevents damage to the plug during moulding of the valve body and prevents the plug from being bonded to the valve body, or the valve body shrinking onto the plug.

Abstract: The invention relates to running gear for railway vehicles having a low-lying loading bridge, consisting of at least two sets (4) of wheels with a small axle base and a running gear frame consisting of lateral faces (1) and crossmembers (2) between two axles in each case, the sets (4) of wheels being braced in the running gear frame via the axle bearings (3), and the running gear being connected with false pivot to the vehicle frame solely via a bearing leaf spring (10) and a shackle suspension (11), each lying laterally lengthwise. 
<??>The object of the invention was to improve the rolling characteristics in this running gear, to optimise the running behaviour on straight track and in bends with the arrangement of the required transverse clearance of the running gear and to make it more favourable by the use of long shackles. The power transmission from the loading bridge via the bearing leaf spring (10) into the running gear was to be improved. 
<??>This object is achieved by the fact that the bearing leaf springs (10) are arranged on spring brackets (5) arranged on the outside on the lateral faces (1) of the running gear frame laterally between the clearance gauge (6) and the loading space (8) of the vehicle and above the wheels.

Date Apr. 2, 1992.The device serves to manipulate the healds or drop wires from their separation from a stack via the drawing-in of the warp threads up to the transfer to supporting members provided for arranging in a weaving machine and it contains holding devices for accepting the separated healds or drop wires and for positively transporting them to a drawing-in station and a transfer station, positioning elements arranged in the area of the drawing-in station, and transfer devices, arranged in the area of the transfer station, for transferring the healds or drop wires having a drawn-in warp thread to the supporting members. Consequently, only a single type of manipulating arrangement is required for manipulating the healds and drop wires from their separation up to the transfer to the supporting members. That results in a substantial reduction in potential sources of error and thus in the susceptibility to trouble. In addition, only two interfaces are necessary: one leading to the separating station and one at the transfer station leading to the supporting members.
