  • Patent number: 11771943
    Abstract: A holding device for using gym equipment for the purpose of muscle building training. The holding device has a handle part and a bracket, and the hand of a person using the holding device can be inserted between the handle part and the bracket. The hand side of the handle part is convexly curved with the exception of local depressions and/or perforations, and parts for releasably securing a dumbbell plate can be releasably secured to the lower face of the handle part. The hand side of the handle part has four groove-shaped depressions which are dimensioned and spaced from one another such when using the holding device as intended with a hand placed on the hand side, each finger is positioned in a respective depression of the groove-shaped depressions with the exception of the thumb.

  • Patent number: 11594368
    Abstract: An assembly for connection to a high-voltage system has multiple single-phase transformers each having a transformer tank which is filled with a fluid and in which a core with at least one winding is situated. At least some of the windings of the single-phase transformers are connected to one another, forming a neutral point. A short-circuit voltage curve or impedance of the assembly can be adapted to different requirements. The windings are each connected to the neutral point via a switchover unit and a choke winding. The choke winding has multiple tappings, and the switchover unit is configured to select the tapping via which the winding in question is connected to the neutral point.
