Abstract: A brush holder assembly is designed so as to be prefabricated in automatic assembly machines. All the components of the assembly are located on a single side of an insulated carrier plate. The components are connected together by means of electrically conductive grommets which are fixed in the carrier plate. A vibration-resistant holder assembly is thus formed which can be assembled with less cost than other such assemblies which require hand labor.

Abstract: Apparatus for crimping filaments using turbulent heated fluids to which the filaments are exposed in two treatment chambers connected to one another. The first treatment chamber is constructed in two parts, the parting plane between the two parts is stepped and the filament guide means are intersected by the parting plane. The filaments are easy to introduce and the operating temperature need not be reduced in the event of any filament breaking.
