Abstract: A Synchronous Positioning Frame Assembly Machine having a plurality of extension wings (48) arranged to precisely locate miter clamps (40) containing captive sliding rails (46) that create a secondary motion to connect small and large frame members. Artist canvas frames, picture frames and other rectangular or square frames such as mirror frames made from mitered members being joined with glue or other mechanical means are precisely brought together at right angles and in a flat plane. Rotary motion of a central rotating shaft (54) linked (50) to the sliding rails (46) positions the clamps (40). A mechanically or manually operated torque lever (56) with knob (58) provides the prime mover force that moves the clamps in a synchronized manner while applying a clamping force to hold the frame members A, B, C, D together with a ratchet (68) and pawl (88) stop for the required assembly time of glue cycle, manual or mechanical fasteners.

Abstract: A surgical microscope apparatus and method for using the same for use while suturing an incision in the cornea for reconfiguring the cornea to a spherical surface having a radius of curvature of a predetermined magnitude, the microscope system including means for projecting an image onto the cornea, means for optically splitting the image into a plurality of images within the surgical field of view for viewing through the binocular eyepieces and means for adjusting the optical system to orient the images into a predetermined alignment and configuration indicative of the radius of curvature, the alignment and configuration occurring when the cornea sutures are tensioned correctly to indicate a spherical surface of the predetermined radius of curvature. The means for optically splitting the images are so-positioned to permit a portion of the surgical field of view to pass through the microscope undeviated to enable the surgeon to utilize the necessary suturing tools without multiple images of the tools.
