Exercise machine (pref. bicycle) of non-corrodible materials - for use underwater in a therapeutic, e.g. sea-water, bath

摘要

The submersible parts of the machine are of non-corrodible materials. Pref. parts are of nickel, chrome, molybdenum austenitic steel. The feet are of epoxy resin. The brakes (which for a bicycle, are pref. of caliper type and work directly on the pedal wheel) are lined with 'Ferodo 18A' and the saddle is of polyester, perhaps coated with polyethylene chlorosulphone.
