Abstract
Abstract A variable-orientation mechanism which provides 6* of freedom for positioning samples. A sample-holder block is mounted to rotate about a first axis carried by a yoke which is pivoted about a second axis located at right angles to the first. The yoke is in turn carried by a support of revolution which rotates about a third axis located at right angles to the other two axes. The movements of the sample-holder about the three axes are controlled independently by a set of differential pinions and a movement produced by three concentric shafts carried by a support sleeve and driven in rotation by means of engageable operating knobs being transmitted to the differential pinions by means of a set of three rods having terminal helical screws. Means are additionally provided for displacing the support sleeve with respect to an outer cylindrical casing and independently in the direction of their common axis, in a direction at right angles to said axis and in rotation about said axis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
210 words
A variable-orientation mechanism with six degrees of freedom for positioning samples comprising a sample-holder block mounted to rotate about a first axis carried by a yoke, said yoke being pivoted about a second axis located at right angles to the first axis, said yoke being in turn carried by a support of revolution rotating about a third axis at right angles to the axes aforesaid, a set Of pinions mounted on said support controlling independently the movements of the sample-holder block about the three axes, ring gears on said support, gearing means between said ring gears and said pinions for driving said pinions, a set of three rods, helical-thread screws on the ends of said rods, gearing means between said ring gears and said screws for transmitting movement to said ring gears and to the differential pinions, three toothed wheels rotating said rods and rigidly fixed to three concentric shafts, a support sleeve carrying said shafts, said shafts being driven in rotation by engageable operating knobs, a two-part cylindrical casing mounted coaxially with said sleeve and means for displacing said sleeve with respect to said casing independently in the direction of the common axis thereof, in a direction at right angles to said axis and in rotation about said axis.
Claim 2
Dependent Claim
210 words
A variable-orientation mechanism with six degrees of freedom for positioning samples comprising a sample-holder block mounted to rotate about a first axis carried by a yoke, said yoke being pivoted about a second axis located at right angles to the first axis, said yoke being in turn carried by a support of revolution rotating about a third axis at right angles to the axes aforesaid, a set Of pinions mounted on said support controlling independently the movements of the sample-holder block about the three axes, ring gears on said support, gearing means between said ring gears and said pinions for driving said pinions, a set of three rods, helical-thread screws on the ends of said rods, gearing means between said ring gears and said screws for transmitting movement to said ring gears and to the differential pinions, three toothed wheels rotating said rods and rigidly fixed to three concentric shafts, a support sleeve carrying said shafts, said shafts being driven in rotation by engageable operating knobs, a two-part cylindrical casing mounted coaxially with said sleeve and means for displacing said sleeve with respect to said casing independently in the direction of the common axis thereof, in a direction at right angles to said axis and in rotation about said axis.
Claim 3
Dependent Claim
61 words
A mechanism in accordance with claim 1, said two parts of said cylindrical casing being interengaged by a dovetail groove means formed in a direction at right angles to the direction of the axis of said support sleeve, said means for displacing said sleeve with respect to said casing including a screw and nut means for controlling the relative displacement thereof.
Claim 4
Dependent Claim
53 words
A mechanism in accordance with claim 1, said means for displacing said sleeve with respect to said casing including a threaded portion coacting with a capstan nut secured against translational motion with respect to said cylindrical casing and rotation of said nut causing displacement of said sleeve in the direction of its axis.
Claim 5
Dependent Claim
58 words
A mechanism in accordance with claim 1, said means for displacing said sleeve with respect to said casing including a crank-plate means for actuating a helical-thread screw coacting with a set of teeth formed in the outer surface of said support sleeve, the threads of the screw being parallel to the direction of the axis of said sleeve.
