Abstract: A fiber spinning device and process for manufacturing a web of fibers in the nature of a homogeneous mixture of fibers of different characteristics. Monocomponent fibers of different polymers can be extruded side-by-side from the same die system. Sheath/core bicomponent fibers can be alternated with monocomponent fibers formed of the same core polymer as used in the bicomponent fibers. Bicomponent fibers having a common core polymer and different sheath polymers can be extruded from alternate spinneret orifices in the same die plate. Multiple distribution plates are provided with surface grooves or depressions to direct polymer materials from independent sources to only selected spinneret openings in an array of spinneret openings while maintaining the polymers segregated from each other.

Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a first dirt collecting chamber and a second dirt collecting chamber separated by an apertured wall. An inlet opening is formed in the dirt cup and communicates with the first dirt collecting chamber for inputting a stream of dirt laden air into the first dirt collecting chamber. An exhaust opening is formed in the second dirt collecting chamber for allowing the filtered air stream to exit the dirt cup. The aperture wall includes a pre-filter for filtering coarse particles from a stream of dirt laden air and depositing the coarse particles in the first dirt collecting chamber. A filter member is positioned within the second dirt collecting chamber and communicates with the exhaust port. The filter element filters fine particles from the air stream and deposits the fine particles within the second dirt collecting chamber.

Abstract: In order to regenerate the heat exchanger material located in the various segments of a housing section (2) of a regenerative post-combustion device (1), fresh air is fed via the flushing air connection (11) into the combustion chamber (8) of this post-combustion device (1), is heated there by a burner (9), and is fed to the rotary distributor (5) via a segment of the heat exchanger material. Heated air which, when passing through the heat exchanger material has picked up contaminants deposited thereon is fed to the inlet or outlet connection (4, 10) of the post-combustion device (1) via the rotary distributor (5) and, from there, is introduced once again into the combustion chamber (8). The rotary distributor (5) of the thermal post-combustion device (1) stops during this process which is continued until the heat exchanger material is heated to a temperature at which the contaminants absorbed by the heat exchanger material are released and combusted in the combustion chamber (8).
