Nucleonic gauges with traversing heads, and drive therefor

Claim 2

A gauge-traversing system for assuring accurate registration between a source head and a detector head throughout the range of their traversing movement, comprising guide means mounting said heads in superimposed spaced relation and defining a pair of transverse parallel paths along which said heads may be moved in said traversing movement, flexible interconnecting tension means of a defined length joining said heads together in an endless closed loop for concurrent movement and being formed with a pair of transversely oriented loop portions with one each of said heads being connected in one run of each of said loop portions, and means for imparting translatory movement to said flexible means to effect said traversing movement of said heads.

Claim 3

The traversing system of claim 1 including roller means for applying a tension force to said flexible means.

Claim 4

A gauge-traversing system for assuring accurate registration between one gauging head including a source of penetrating radiation and a radiation detector head throughout the range of their traversing movement, comprising guide means mounting said heads in superimposed spaced relation and defining a pair of transverse parallel paths along which said heads may be moved in said traversing movement, elongated flexible tension means of substantially constant length interconnecting said heads formed in a closed loop and defining the sole motivating connection between said heads so that translatory movement of said tension means effects concurrent traversing moving of each of said heads in the same direction by the same amount, and means for imparting translatory movement to said flexible tension means.

Claim 5

A gauge-traversing system for assuring accurate registration between one gauging head including a source of penetrating radiation and a radiation detector head throughout the range of their traversing movement, comprising guide means mounting said heads in superimposed spaced relation and defining a pair of transverse parallel paths along which said heads may be moved in said traversing movement, elongated flexible tension means of substantially constant length interconnecting said heads formed in a closed loop and defining the sole motivating connection between said heads so that translatory movement of said tension means effects concurrent traversing moving of each of said heads in the same direction by the same amount, and means for imparting translatory movement to said flexible tension means.

Claim 6

A nucleonic gauge-traversing system for assuring accurate registration between a radioactive source head and a detector head throughout the range of their traversing movement, comprising a pair of spaced apart stanchions, rigid tube means extending between said stanchions defining a traversing way, means mounting said heads for traversing guided movement on said tube means, an elongated flexible drive member of a defined length connected in a closed loop including each of said heads, means maintaining said loop in tension, said loop being formed in first and second runs with each run comprising two lengths of said member extending transversely between said stanchions sheave means in each of said stanchions supporting each run of said member, one length of each of said runs being received within said tube means and the other length of each of said runs engaging the associated one of said heads, and drive means for imparting translatory movement to said member.

Claim 7

A nucleonic gauge-traversing system for assuring accurate registration between a radioactive source head and a detector head throughout the range of their traversing movement, comprising a pair of spaced apart stanchions, rigid tube means extending between said stanchions defining a traversing way, means mounting said heads for traversing guided movement on said tube means, an elongated flexible drive member of a defined length connected in a closed loop including each of said heads, means maintaining said loop in tension, said loop being formed in first and second runs with each run comprising two lengths of said member extending transversely between said stanchions sheave means in each of said stanchions supporting each run of said member, one length of each of said runs being received within said tube means and the other length of each of said runs engaging the associated one of said heads, and drive means for imparting translatory movement to said member.
