  • Patent number: 4381285
    Abstract: The present invention comprises a contact lens sterilizing device (10,54,118) which chemically disinfects contact lenses (L) in a cell (20,64,134) containing antimicrobial solution (42,104,144) and which subsequently transfers the lenses (L) to a storage cell (22,66,136) containing storage solution (44,106,146). Momentum generated as the striker arm (6) of a mechanical timer (2) snaps from a first position to a second position is utilized to propel a cage (C,70,140) holding the contact lenses (L) from the sterilizing cell (20,64,134) to the storage cell (22,66,136), thereby effecting the transfer operation. In one embodiment (10) of the present invention, the striker arm momentum is indirectly imparted to the contact lens cage (C) via a flipper (28). In other embodiments (54,118) of the present invention, the striker arm momentum is directly imparted to the contact lens cage (70,140) via a hook (72,142) integrally formed on the cage (70,140).

  • Patent number: 4260252
    Abstract: A method and apparatus for immobilizing a contact lens without distortion to facilitate accurate measurement of its physical dimensions. The lens is floated on the surface of a liquid just out of contact with a support member. The support member is disposed to interact with the lens, through surface tension effects of the liquid, to immobilize the lens on the surface of the liquid.
