Plastic bridge assembly holds permanent magnets to plastic tap water pipe

摘要

Domestic tap water flows through a plastic pipe on and around which are mounted a number of permanent magnets whose fields are directed at particles flowing with the water. The novelty is that the magnets are mounted on a plastic bridge housing (10) consisting of two (10a,10b) or more parts, and that the inner face (10) of the housing has a moulded carrier (12,13,14) surface which secures the permanent magnets (8,9) and which when assembled surround the plastic pipe (2a,2b,2c).
