Universal Sliding Resistances, Figure, comprising a combination of 2 sliding resistances whose 

 resistances are of different magnitude and varying loading capacity, it being possible to use 

 these as required in series, parallel, or singly by means of a connecting strap. An extermdy 

 complete range of tine adjustment of the current-value to be regulated is possible with these 

 resistances and in consequence they can be highly recommended both for this reason and by- 

 virtue of their many sided uses for practical and scientific purposes.
