Abstract
Abstract A device for scanning a flat surface having a given orientation between two arbitrary orthogonal planes P and P', the device comprises: - a carrier arm whereon the detector can slide and be orientated, the said detector carrier arm itself being arranged to be slidable on an intermediate arm which constitutes, in conjunction with the detector carrier arm, a plane which is parallel to the plane P, - a carrier arm whereon the intermediate arm is arranged to be slidable and which constitutes, in conjunction with the latter, the plane P" which is perpendicular to the planes P and P' the said carrier arm being provided with means for displacement in a plane parallel to the plane P'.

Claim 1
Independent Claim
220 words
Apparatus for scanning a body for scintillations along a surface having any one of a plurality of different orientations which are parallel to a first horizontal direction, said apparatus comprising: a scintillation detector; a detector carrier arm assembly along which said detector is movable in a first horizontal direction, said detector being oriented perpendicular to said first horizontal direction and said detector carrier arm assembly being axially rotatable about said first horizontal direction, so that said detector may be oriented in any one of a plurality of different directions which are perpendicular to said first horizontal direction; an intermediate arm assembly along which said detector carrier arm assembly is movable in the vertical direction; a carrier arm assembly along which said intermediate arm assembly is movable in a second horizontal direction perpendicular to said first horizontal direction; a first drive motor mounted on said carrier arm assembly and coupled to said intermediate arm assembly for moving said intermediate arm assembly in said second horizontal direction; a second drive motor mounted on said intermediate arm assembly and coupled to said detector carrier arm assembly for moving said detector carrier arm assembly in the vertical direction; and a third drive motor mounted on said detector carrier arm assembly and coupled to said detector for moving said detector in said first horizontal direction.

Dependent Claim
220 words
Apparatus for scanning a body for scintillations along a surface having any one of a plurality of different orientations which are parallel to a first horizontal direction, said apparatus comprising: a scintillation detector; a detector carrier arm assembly along which said detector is movable in a first horizontal direction, said detector being oriented perpendicular to said first horizontal direction and said detector carrier arm assembly being axially rotatable about said first horizontal direction, so that said detector may be oriented in any one of a plurality of different directions which are perpendicular to said first horizontal direction; an intermediate arm assembly along which said detector carrier arm assembly is movable in the vertical direction; a carrier arm assembly along which said intermediate arm assembly is movable in a second horizontal direction perpendicular to said first horizontal direction; a first drive motor mounted on said carrier arm assembly and coupled to said intermediate arm assembly for moving said intermediate arm assembly in said second horizontal direction; a second drive motor mounted on said intermediate arm assembly and coupled to said detector carrier arm assembly for moving said detector carrier arm assembly in the vertical direction; and a third drive motor mounted on said detector carrier arm assembly and coupled to said detector for moving said detector in said first horizontal direction.
Claim 3
Dependent Claim
68 words
Apparatus as defined in claim 1 and further comprising a double friction plate rotatably mounting said detector carrier arm assembly to said intermediate arm assembly, said double friction plate having at least five predetermined detent positions corresponding to said detector being oriented in the vertical direction, in two opposing horizontal directions and in two inclined directions which respectively form the same angle with said two opposing horizontal directions.
