  • Method of producing an electrode-separator winding, electrode-separator winding and button cell with such a winding
    Patent number: 11114701
    Abstract: A method of producing an electrode-separator winding includes feeding a first current collector, feeding a second current collector, feeding two separators in strip form to a winding device, and winding the first and second current collectors and the separators to form a winding with a sequence, wherein a contact strip is welded on at least one of the contact sections of the current collectors, or at least one of the contact sections is folded over to form a contact strip, and at least one of the separators is reinforced in at least one risk region in which the at least one separator within the completed electrode-separator winding lies against the at least one contact section in which the contact strip is welded on or against the at least one contact section folded over to form a contact strip.

  • Blower or pump with capillary filter for replenishment of oil separated by vacuum pump
    Patent number: 5114320
    Abstract: A housing 3 disposed below the rotor accommodates a driving motor 13, shaft bearings 14, 15 and an oil sump 21. An evacuating line 31 which traverses the wall the housing 3 connects a vacuum pump to the interior 18 of the housing. In order to avoid the loss of oil in the housing or the bearings, the evacuating line 31 and the oil sump 21 are directly connected.
