Abstract: A residual load disconnector switch (1) includes a rotary switch body (23), which includes a contact blade (24, 25, 26, 27), that is rotatable about an axis (A) and is arranged between a feed line connection (20) and a discharge line connection (21), and includes end-side contact surfaces (28, 29, 30, 31) protruding in a radial direction. The contact surfaces, in a closed rotary position (S1) of the rotary switch body (23), are in touching contact with the feed line connection (20) and with the discharge line connection (21). In an open rotary position (S2) of the rotary switch body (23), the contact surfaces are each spaced with respect to the feed line connection (20) and with the discharge line connection (21). The residual load disconnector switch (1) is rotationally limited in one rotational direction for performing switching movements and can be actuated unidirectionally and cyclically.

Abstract: A brush block is provided for transmitting currents to a slip ring using at least one multi-wire slip element with a plurality of parallel connected multi-wire slip elements that are distributed one behind the other in the direction of slip following an imaginary curve. The brush block has a multi-wire slip element support with a curved inner wall on which the multi-wire slip elements are disposed in layers that overlap in scale-like fashion.

Abstract: A method of pretreating suspended flexible containers of the type including an upper tubular part of a flexible material and a lower bottom rigid part. The method comprises applying to a lower edge portion of the upper tubular part a pulling force in a longitudinal direction towards the lower bottom part so that the upper tubular part elongates to its maximum length, and subsequent fixedly connecting the lower edge of the upper tubular part to the lower bottom part. An arrangement for pretreating such containers comprises means for suspending the container by an upper edge portion of the tubular part, pulling means for pulling the lower edge of the upper tubular parts in a longitudinal direction to the lower bottom part and for subsequently fixedly connecting the lower edge of the upper tubular part to the lower bottom part, means for connecting the pulling means to the upper tubular part, and means for connecting the pulling means to the lower bottom parts.
