Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
A carrier for use in determining a physical characteristic of a conduit, said carrier comprising: (a) an elongated carrier rod; (b) a fixed pivot mounting member rigidly affixed to one end of said carrier rod; (c) a first group of linkage arms pivotally connected to said fixed pivot mounting member; (d) a movable pivot mounting member slideably mounted over said carrier rod; (e) a second group of linkage arms pivotally connected to said movable pivot mounting member; (f) pivot connections and transducer holders intermediate said fixed and said movable pivot mounting members linking said first group of linkage arms with said second group of linkage arms, said pivot connections and transducer holders adapted to move radially outward from said carrier rod upon movement of said movable pivot mounting member toward said fixed pivot mounting member; and (g) an ultrasonic transducer attached to each of said transducer holders.
Claim 2
Dependent Claim
147 words
A carrier for use in determining a physical characteristic of a conduit, said carrier comprising: (a) an elongated carrier rod; (b) a fixed pivot mounting member rigidly affixed to one end of said carrier rod; (c) a first group of linkage arms pivotally connected to said fixed pivot mounting member; (d) a movable pivot mounting member slideably mounted over said carrier rod; (e) a second group of linkage arms pivotally connected to said movable pivot mounting member; (f) pivot connections and transducer holders intermediate said fixed and said movable pivot mounting members linking said first group of linkage arms with said second group of linkage arms, said pivot connections and transducer holders adapted to move radially outward from said carrier rod upon movement of said movable pivot mounting member toward said fixed pivot mounting member; and (g) an ultrasonic transducer attached to each of said transducer holders.
