Abstract
Abstract In a scanning X-ray machine involving at least rotational movement of a source about an axis, a flexible connection arrangement is provided for electricity, coolant and the like in which a connection handling arrangement includes a guide to form at least one guided loop between fixed and movable parts of the machine and inside the machine cover, the connection being taken in from and returned to the loop with said movement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
In a scanning X-ray machine in which an X-ray source is supported inside a machine cover for scanning movement to direct radiation along substantially coplanar paths in various directions and has at least one flexible connection between movable and fixed machine parts, a connection handling arrangement including guide means to form at least one guided loop extending unsupported within the machine cover of each flexible connection, said guide means having a connection guide which is movable with the source and to which said connection is attached to take in and return said connection from and to said loop with movement of the source.
Claim 2
Dependent Claim
103 words
In a scanning X-ray machine in which an X-ray source is supported inside a machine cover for scanning movement to direct radiation along substantially coplanar paths in various directions and has at least one flexible connection between movable and fixed machine parts, a connection handling arrangement including guide means to form at least one guided loop extending unsupported within the machine cover of each flexible connection, said guide means having a connection guide which is movable with the source and to which said connection is attached to take in and return said connection from and to said loop with movement of the source.
Claim 3
Dependent Claim
66 words
A machine according to claim 1 including means for orbiting the X-ray source to direct radiation along paths inclined in different directions with respect to each other but being at about the same angle to an axis and wherein the connection guide is curved about said axis to vary the size of the loop with said movement and to thereby form a loop of variable size.
Claim 4
Dependent Claim
56 words
A machine according to claim 2 including means for moving the X-ray source along lines transverse to said axis to direct radiation along directions which are substantially parallel to each other for each line and wherein the connection guide causes the loop to roll along the connection with said movement and forms thereby a rolling loop.
Claim 5
Dependent Claim
39 words
A machine according to claim 3 in which the curved guide is between the loop of variable size and the rolling loop, the rolling loop extending to said source and being inclinable with said orbiting movement of the source.
Claim 6
Dependent Claim
28 words
A machine according to claim 2 in which the curved guide comprises a drum to which the connection is attached and about which drum the connection is wound.
Claim 7
Dependent Claim
31 words
A machine according to claim 3 in which the rolling loop is formed to substantially the minimum bending radius of the connection between a straight fixed and a straight movable guide.
Claim 8
Dependent Claim
46 words
A machine according to claim 2 including a floor engaging machine frame, wherein the source and curved guide are orbited through at least 270° about a horizontal axis and the variable loop is guided in a vertical plane within the floor engaging frame of the machine.
Claim 9
Dependent Claim
22 words
A machine according to claim 7 in which the loop is guided for movement in a curved path in the vertical plane.
Claim 10
Dependent Claim
61 words
A machine according to claim 5 including a floor engaging machine frame, wherein the source and drum are orbited through at least 360° about a horizontal axis and the loop is guided in a vertical plane in a curved path within the floor engaging frame of the machine and is further guided in the horizontal plane within the floor engaging frame.
