Fusehead bridge wire

In order (d initiate the delay element it is necesssry to use an electric fusehead which is also gasless. One such fusehead is made by dipping the bridge wire in a suspension of a mixt of Zr powder 50 8i Pb 2-Mononitro-resorcinate 50% in a 5% sola of NC in amyl acetate... 

B) Bridge Type Electric Cap consisted of a cylindrical casing Ni-plated brass or Ni-plated steel). See Fig E19, contg the following items a)Bridge wire ( . fuse ) (such as of 80/20-Ni/Cr alloy was soldered to two leads consisting of two metal foil strips separated by a mill-board, serving as an insulator b) Fusehead c) Molded Plastic insulator d) Brass contact... 

For pcepn of fusehead could be used the method A6 developed at Troisdorf Fabrik of Dynamic AG, located near Koln. For this the tip of bridge wire was dipped succesively into the following liquid compns ... 

The two legs of each fusehead were then bonded together with Mipolan (jnixt of polyvinyl chloride, tricresylphosphate butyleneglycolphthal ate), the tips of the teeth suitably bent and the bridge wire soldered into position. After dipping the bridge wires into fusehead compns. the back of the comb was sheared off (Ref 2,p Ger...
