Abstract: ABSTRACT OF THE DISCLOSURE A surgical microscope apparatus for use while suturing an incision in the cornea for configuring the cornea to a spherical surface having a radius of curvature of a predetermined magnitude is disclosed.  The micro-scope system includes a light source for projecting an image onto the cornea and prisms for optically splitting the image on the cornea into a plurality of images within the surgical field of view for viewing through the binocular eyepieces.  The optical system can be adjusted to orient the images into a predetermined alignment and configuration indicative of the radius of curva-ture, the alignment and configuration occurring when the cornea sutures are tensioned correctly to indicate a spherical surface of the predetermined radius of curvature.  The prisms 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.  In  a  first embodiment a fixed location prism array is utili-lized for optically splitting the image and the optical system is adjusted by varying the magnification powers of the microscope.  In a second embodiment, rotary prisms are in a fixed position within the optical path for optically splitting the image and the  optical system is adjusted by varying the prism power.

Abstract: WALKING DOLL                   ABSTRACT           A walking doll is described having a pair of side by side legs which automatically pivot forward-ly when lifted off the ground.  The legs include movable, side by side buttocks.  The doll may be connected to a stroller through a handle that oscillates from side to side as the stroller is forwarded.  When the doll is connected to the handle the doll rocks from side to side causing one leg after another to be lifted from the ground.  As a leg is lifted from the ground an eccentric weight within the leg causes the leg to step forwardly until the handle is rotated in the opposite direction at which time the leg again contacts the ground and the other leg is lifted off the ground.          The handle is oscillated by a cam follower which follows a cam rotated by an axle of the stroller.

Abstract: ELECTRONIC GEAR CHECKER            Abstract of the Disclosure A functional gear checking machine for determining a number of gear characteristics from a composite input signal received from a linear voltage differential transformer is disclosed.  The signal from the sensing transformer is coupled to a demodulation circuit which, in turn, is coupled to several types of signal processing circuits, each of which contains a memory, and each of which processes and separates the components of the composite signals in order to provide output signals that are indicative of the desired gear characteristics.  More particularly, the use of successive approximation means in a system which produces an analog electrical signal that undergoes an analog signal excursion of a maximum magnitude in a particular direction from a reference level comprising the steps of estab-lishing a stored digital count that is translatable into an initial analog signal level that is of a greater magnitude in the particular direction than the excursion, reducing the digital count in the particular direction in digital steps until it is translatable into a reduced analog signal level that is approximately equal to the excursion and producing an output that represents the value of the reduced analog signal level.

Abstract: ABSTRACT Shoe Upper Conforming Machines A single-station combined toe and side lasting machine comprises pulling over instrumentalities 20, 22 for tensioning an upper over its last, toe lasting instrumentalities, including toe wipers 38, toe pad 48 and toe band 50, a heel support 56, two adhesive applying nozzles 28 and side lasting instrumentalities 114 constituted by two lasting rollers 1760 In operation, with the upper tensioned, first the shoe is clamped by the toe lasting instrumentalities and heel support to allow adhesive to be applied progressively along opposite side portions from the toe to heel breast.  Then the lasting rollers operate progressively from the ball region to the heel breast, and, when the rollers have cleared the ball region, the inwiping movement of the toe wipers is completed.  The nozzles and side lasting rollers are mounted on a common carriage 26 which moved rectilinearly, supports 116 for the rollers being mounted for movement thereon about three perpendicular axes 82, 122, 140. The rollers are also supported by carriers 174 on said supports for pivotal movement about a further axis 170.  In this way, the rollers can follow the contour of the shoe bottom and also the angular relationship of the rollers with the shoe bottom can be varied in two planes.  For following the shoe bottom contour the rollers (and also, independently, the nozzled) are moved by stepping motors 80, 166 (96) in accordance with a program instruction, under the control of which also the angular relationship is varied.  The carriers for the rollers also support wiping fingers 222 which ensure that the lasting margin of the upper is correctly positioned for engagement by the rollers.

Abstract: ABSTRACT OF THE DISCLOSURE            Delayed coke is desulfurized by first contacting the coke with an active sulfur-bearing gas at a temperature high enough to produce a reaction between the sulfur in the coke and the active sulfur in the gas, and then holding the coke in contact with the gas at said high temperature for approximately one hour.  An alternative process provides for desulfurization of delayed coke by modifying the second step of the prior process to dilute or replace the sulfur-bearing gas with an inert gas.  In a third alternative, the foregoing process is further modified by lowering the temperature during the second or holding step to maintain the reaction between the sulfur-bearing gas and the coke.
