Abstract: Method and apparatus for collecting hangers hanging from overhead or a conveyor rail installed in, for example, a meat processing plant and for returning such collected hangers to the conveyor rail including a guide bar installed under the conveyor rail. The conveyor rail and the guide bar are provided with parallel curved portions at the ends so that the end of the guide bar is positioned above the end of the conveyor rail, thus the hangers having been suspended from the conveyor rail are inverted and brought upside-down at the end of the conveyor rail and suspended from the guide bar via the hook portions of the hangers. The thus upside-down hangers are collected on a carrying truck, and they are returned to the conveyor rail using a hanger transfer disk rotatably installed between the carrying truck and the guide bar.

Abstract: A novel magnetic recording medium consisting of a base material, magnetic particles and a specific polyurethane-based binder containing incorporated sulphonate groups, a process for preparing such a magnetic recording medium which comprises coating a base material with a coating material comprising (i) an organic solvent, (ii) a polyurethane binder containing chemically incorporated sulphonate groups and (iii) magnetic particles and the most preferred binder composition therefor comprising a hexandiol-(1,6)-polycarbonate-based polyurethane.
