Total Claims: 4
Claim 1
Independent Claim
83 words
A system of pulsators including bobbins, for an electroophthalmic device adapted to be placed about the forehead of a person, comprising a pulsator mounting with openings fOr the pulsators, in the form of non-circular cylinders made convergently in parallel layers, the pulsators being slidably fixed in said openings with mutual intersection of teeth made in the bobbins included in the pulsators, with side flanks of pins seated in holes in said mounting, said pins going through all of said layers of the pulsators.
Claim 2
Independent Claim

Claim 3
Dependent Claim
47 words
The system of pulsators as defined in claim 1, wherein said pulsator mounting is in the shape of a ring-sector having therein said openings for the pulsators in parallel planes perpendicular to the axis of said ring-sector and convergent in each of said planes with said axis.
Claim 4
Dependent Claim
36 words
