Induction Coils and Accessories. 



Our output of Induction Coils up to the present amounts to over 3500. 



Our Induction Coils, which are constructed from an experience extending over many years, 

 and which are unsurpassed in efficiency by any other make, are built of the best materials, which are 

 submitted to the most stringent tests before being worked up. The reels are made of stout tubes with 

 end discs and ebonite jacket and, with the exception of the very small apparatus, can be detached 

 from the stands. The method of constructing the secondary coils ensures that each individual winding 

 is thoroughly well insulated. 



In the case of sizes 7 15 a, types A, B, C, D and E, the Primary Coils arc enclosed in a separate 

 ebonite tube from which they can be taken out. 



We supply the Induction Coils either with a base to enable them to be placed on a table, or, 

 if desired, with Wall Bracket, the prices of both patterns being the same. 



For working with Wehnelt "Interrupters the coils are fitted with controllable self-induction 

 (thus varying also the ratio of transformation and the secondary voltage attained). This regulation 

 can either be carried out by Plugs or with a Pachytrope (Multiple Commutator). 



We supply our Induction Coils in the following patterns: 



I. Induction Coils with Normal Winding. 



(l) For Wehnelt Interrupters, with Condenser, viz: 



(a) Type A, with Multiple Commutator for varying the self induction of the primary coil. ct. I'ii: 112.533.
