Filed: 2002-10-18
Abstract: The present invention provides a apparatus for correcting eyesight characterized in that a cornea pressure member is slidably attached to a cap-like cornea sucking member, and a cooling liquid injection channel is formed through the cornea pressure member. The cornea sucking member is further provided with an air sucking port and a liquid ophthalmic medicine injection port. The cornea sucking member is applied to a cornea which has been softened by being warmed by any known warming method; said member pulls the cornea forward by sucking air through the air sucking port; and in the mean time the cornea pressure member presses the cornea with its head portion so as to modify the shape of the cornea to a desired one.      Immediately thereafter, a cooling liquid is passed through the cooling liquid injection channel to rapidly cool the cornea, thereby stabilizing the corrected shape of the cornea.

Title: Safety device for cord-operated control system
Inventor: BOHLEN JORG
IPC: E06B9/322
Filed: 2002-12-16
Abstract: A cord-operated control system for a venetian blind, in which a housing, attached to the head rail, holds a first drive wheel that is operatively connected to a driven bind member that rotates in opposite directions to open and close the blind with rotation of the first drive wheel in opposite directions and a second drive wheel that is operatively connected to the first drive wheel, so that the first drive wheel rotates in opposite directions with rotation of the second drive wheel in opposite directions. An endless loop operating cord is looped over the second drive wheel, so that an axial pulling force on only one of the depending portions of the operating cord on opposite sides of the second drive wheel causes the second drive wheel to rotate in one of the opposite directions. As a safety feature, a release disconnects the drive wheels from each only if there is an axial pulling force on both depending portions of the operating cord simultaneously.
