Abstract
Abstract A roll alignment method and apparatus having a platform adapted for sequential placement on a plurality of rollers to be made codirectional in which a gyro-controlled optical reflective device is gyro-stabilized on the platform with reference to the first of the rollers so that the platform can be moved to subsequent rollers for alignment of the subsequent rollers with the gyro reference.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
A gyroscopic alignment device comprising: an elongated base having V-block feet for positioning said base on an elongated cylindrical member; a gyroscope and housing therefor mounted for free movement at one end of the elongated base; a reference plane mirror mounted on the housing of said gyroscope adapted to move with said gyroscope and housing; an optical system mounted at the other end of said elongated base for determining alignment of the reference plane mirror with respect to the optical system, and means for aligning said optical system and reference plane mirror relative to each other.
Claim 2
Dependent Claim
96 words
A gyroscopic alignment device comprising: an elongated base having V-block feet for positioning said base on an elongated cylindrical member; a gyroscope and housing therefor mounted for free movement at one end of the elongated base; a reference plane mirror mounted on the housing of said gyroscope adapted to move with said gyroscope and housing; an optical system mounted at the other end of said elongated base for determining alignment of the reference plane mirror with respect to the optical system, and means for aligning said optical system and reference plane mirror relative to each other.
Claim 3
Dependent Claim
17 words
A gyroscope alignment device as set forth in claim 1 wherein said optical system comprises an autocollimator.
Claim 4
Dependent Claim
42 words
A gyroscopic alignment device as set forth in claim 2 wherein said autocollimator comprises: an eyepiece; a comparison reticle in the focal plane of said eyepiece; and a beamsplitter for providing an optical path between said eyepiece and said reference plane mirror.
Claim 5
Dependent Claim
47 words
A gyroscopic alignment device as set forth in claim 3 wherein said autocollimator further comprises: a light source on the side of the beamsplitter opposite said eyepiece; a reticle spaced from said light source; and a collimating lens positioned between the beamsplitter and the reference plane mirror.
Claim 6
Dependent Claim
37 words
A gyroscopic alignment device as set forth in claim 1 wherein a reticle is formed on the reference plane mirror and the optical system comprises an eyepiece for viewing the reference plane mirror and a comparison reticle.
Claim 7
Dependent Claim
35 words
A gyroscopic alignment device as set forth in claim 5 wherein there is provided level indicating means mounted on said elongated base oriented in a direction transverse to the longitudinal axis of the elongated base.
Claim 8
Dependent Claim
23 words
A gyroscopic alignment device as set forth in claim 6 wherein there is also provided balancing weight means depending from said elongated base.
Claim 9
Dependent Claim
43 words
A gyroscopic alignment device as set forth in claim 1 wherein said gyroscope and housing are mounted on said elongated base for rotation about two orthogonal axes, said axes being mutually orthogonal to the axis of spin of the flywheel of said gyroscope.
Claim 10
Dependent Claim
131 words
A gyroscopic alignment device comprising: an elongated base having at least one V-shaped groove formed along the bottom thereof for placement of the base on an elongate cylindrical member; a gyroscope and housing therefor mounted for free movement at one end of the elongated base; a reference plane mirror mounted on the housing of said gyroscope adapted to move with said gyroscope and housing; an optical system mounted at the other end of said elongated base for viewing said reference plane mirror comprising; eyepiece lens means; means providing an optical path between said eyepieCe lens means and said reference plane mirror; comparison reticle means interposed in the optical path between said eyepiece lens means and said reference plane mirror for indicating alignment between said optical system and said reference plane mirror.
Claim 11
Dependent Claim
131 words
A gyroscopic alignment device comprising: an elongated base having at least one V-shaped groove formed along the bottom thereof for placement of the base on an elongate cylindrical member; a gyroscope and housing therefor mounted for free movement at one end of the elongated base; a reference plane mirror mounted on the housing of said gyroscope adapted to move with said gyroscope and housing; an optical system mounted at the other end of said elongated base for viewing said reference plane mirror comprising; eyepiece lens means; means providing an optical path between said eyepieCe lens means and said reference plane mirror; comparison reticle means interposed in the optical path between said eyepiece lens means and said reference plane mirror for indicating alignment between said optical system and said reference plane mirror.
Claim 12
Dependent Claim
52 words
A gyroscopic alignment device as set forth in claim 9 wherein said means providing an optical path between said eyepiece lens means and said reference plane mirror comprises a beamsplitter and a collimating lens and said comparison reticle means comprises cross hairs interposed in the focal plane of said eyepiece lens means.
