Patent Images
1. In an underwater device for deep sea use of the type including a water-tight housing, rechargeable energy storage means and energy dissipating means connected thereto, an improved means for charging said rechargeable energy storage means comprising, in combination:
- a secondary winding secured within said water-tight housing and interconnected with said rechargeable energy storage means, said water-tight housing and said secondary winding being substantially coaxial;
a primary winding defining a central opening adapted to receive said water-tight housing in a charging state;
means for positioning said primary winding in substantially radial alignment with said secondary winding in said charging state, said primary winding substantially enclosing said secondary winding in said charging state to define an electromagnetic coupling therebetween; and
means for exciting said primary winding, whereby a charging current is induced in said secondary winding.
