methacrylate provided with radial fins is secured around the core by 

 tape and the wire of the winding. Such inductors were mounted by ce- 

 menting the projecting fins into slots arranged around a recess in the 

 network housing. On top is an inductor which, for electrical reasons, 

 required a core of greater cross-section than could be accommodated in 

 the network when made by the usual toroidal construction. In this case, 

 the effective cross-section of two cores M^as obtained by cementing the 

 cores in a "figure-8" position and by applying the winding so that it 

 threads the hole in both cores. With these constructions, the cement used 

 to secure the inductors does not come into contact with the wire of the 

 winding which is thereby not subject to strains produced by curing of 

 the cement. 



For economy of space and also to reduce the number of soldered con- 

 nections, many of the components' structures contain two or more ele- 

 ments. Inductors and resistors were combined by winding inductors with 

 resistance wire. Separate adjustment of inductance and resistance were 

 obtained by adjusting turns for inductance and the length of wire in a
