Abstract
Abstract This is a device that enables one to control the translation and rotation of an element 15A, B relative to a light beam 38. The device has a rotatable member 12 having a plurality of position-identifying circumferentially spaced openings 14A, B, C, D therein as well as code aperture 16A, B, C for the transmission of a light beam. The rotatable member 12 is mounted on a rotating mounting 20 driven from a motor 26. The mounting 20 is carried by a housing 22 which can be translated by motor 34. The code apertures 16 are read by an optical head 18 and the positional information used in the control of motor 26.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
82 words
A translation/rotation positioning device comprising a rotatable merger with a rotation axis and having a plurality of position identifying circumferentially spaced openings therein, said member having an aperture for the transmission of a light beam, means alignable with said openings for optically reading the presence or absence of an item within the openings, means for rotating the member continuously, and means concurrently operable for moving the member translationally in a place at right angles to the axis of rotation of said member.
Claim 2
Dependent Claim
82 words
A translation/rotation positioning device comprising a rotatable merger with a rotation axis and having a plurality of position identifying circumferentially spaced openings therein, said member having an aperture for the transmission of a light beam, means alignable with said openings for optically reading the presence or absence of an item within the openings, means for rotating the member continuously, and means concurrently operable for moving the member translationally in a place at right angles to the axis of rotation of said member.
Claim 3
Dependent Claim
126 words
Optical or other radiation apparatus comprising a mount for an element to be used in analysing the radiation or tc be analysed using the radiation which element is to be selectively positioned and orientated in the path of the radiation, said apparatus being characterised in that the mount comprises a rotatable member with a rotation axis and having a plurality of position identifying circumferentially spaced openings therein, said member having an aperture for the transmission of a light beam, means alignable with said openings for optically reading the presence or absence of an item within the openings, means for rotating the member continuously, and means concurrently operable for moving the member translationally in a place at right angles to the axis of rotation of said member.
Claim 4
Dependent Claim
126 words
Optical or other radiation apparatus comprising a mount for an element to be used in analysing the radiation or tc be analysed using the radiation which element is to be selectively positioned and orientated in the path of the radiation, said apparatus being characterised in that the mount comprises a rotatable member with a rotation axis and having a plurality of position identifying circumferentially spaced openings therein, said member having an aperture for the transmission of a light beam, means alignable with said openings for optically reading the presence or absence of an item within the openings, means for rotating the member continuously, and means concurrently operable for moving the member translationally in a place at right angles to the axis of rotation of said member.
Claim 5
Dependent Claim
54 words
Apparatus as claimed in claim 2, in which said mount is disposed in a radiation chamber which is evacuated during use and in which each of said rotating means and said moving means comprise electromechanical transducers within the chamber connected to control circuitry external of the chamber by leads sealed through the chamber wall.
