Hello

Soldering a crimped case is a SFM patent dating from 1927

The advantages are :

  1. perfect waterproofness
  2. powder load lighter than for a regular crimping case (therefore the flame is shorter)

JP,

Thanks for the info on the cartridge details. I was wondering what was being made with the device you show.

Thanks,

Ah !!

It is an anti-flat warling device for special buses (with tires but the energy coming from lines as an electric train)
