Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
A PRECESSION MOTION INCLUDING MEANS TO EFFECT THE ROLLING OF A PLANE TANGENT TO AN IMAGINARY COME ALONG A GENERATOR THEREOF, AND MEANS TO EFFECT THE MIGRATION OF SAID GENERATOR AT A CONSTANT ANGULAR RATE AND THE ROTATION OF SAID PLANE WITH RESPECT TO ITS NORMAL AT A CONSTANT RATE BUT IN A DIRECTION OPPOSITE TO THAT IN WHICH IT IS ROLLED, SAID RATES BEING SO RELATED THAT EACH POINT OF THE PLANE MAKES CONTACT WITH A PARTICULAR POINT ON SAID IMAGINARY CONE ON EACH CYCLE.
Claim 2
Dependent Claim
86 words
A PRECESSION MOTION INCLUDING MEANS TO EFFECT THE ROLLING OF A PLANE TANGENT TO AN IMAGINARY COME ALONG A GENERATOR THEREOF, AND MEANS TO EFFECT THE MIGRATION OF SAID GENERATOR AT A CONSTANT ANGULAR RATE AND THE ROTATION OF SAID PLANE WITH RESPECT TO ITS NORMAL AT A CONSTANT RATE BUT IN A DIRECTION OPPOSITE TO THAT IN WHICH IT IS ROLLED, SAID RATES BEING SO RELATED THAT EACH POINT OF THE PLANE MAKES CONTACT WITH A PARTICULAR POINT ON SAID IMAGINARY CONE ON EACH CYCLE.
Claim 3
Dependent Claim
144 words
IN A PRECESSION INSTRUMENT HAVING A FIRST AXIS, A ROTATABLE MEMBER DISPOSED WITH ITS AXIS INTERSECTING SAID FIRST AXIS, AND A DRIVE INCLUDING MEANS TO EFFECT THE TRAVEL AT A CONSTANT RATE OF SAID MEMBER ABOUT SAID FIRST AXIS IN ONE DIRECTION AND MEANS TO EFFECT THE ROTATION OF SAID MEMBER ABOUT ITS AXIS IN THE OPPOSITE DIRECTION, SAID DRIVE ESTABLISHING A MOTION CHARACTERIZED BY THE ROLLING OF A PLANE TO WHICH THE AXIS OF SAID MEMBER IS A NORMAL TANGENT TO AN IMAGINARY CONE ALONG A GENERATOR THEREOF, SAID CONE HAVING A HALF OPENING ANGLE OF 90*-$, SAID ROLLING BEING ATTENDED BY THE MIGRATION OF SAID GENERATOR AT THE CONSTANT ANGULAR RATE W AND THE SIMULTANEOUS ROTATION OF SAID PLANE WITH RESPECT TO THE AXIS OF SAID MEMBER AT THE CONSTANT RATE (1-SIN$)W IN A DIRECTION OPPOSITE TO THE ROLLING OF SAID PLANE.
Claim 4
Dependent Claim
144 words
