Abstract
Abstract A multiple transducer probe for pulse-echo ultrasonic testing, and especially for image-forming at depth within objects, comprising a transducer system focused along a line and having its component transducers situated along an arc of a circle. Separate transmitting and receiving transducers are preferably mounted covering end-to-end quadrants of a conical depression machined in a metallic transducer block. The transducer block is, in turn, mounted for movement on a coupling block having one surface shaped to fit a surface of the object to be tested.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
An ultrasonic inspection apparatus comprising means for generating pulses of sonic energy; means for displaying variations in reflected sonic energy; and at least one transducer, said transducer being connected to said generating means, and said transducer being connected to said display means, said transducer occupying a portion of an arc of a circle and focused along a narrow line perpendicular to the plane of said circle through its center, and perpendicular to the surface of the test object to which the inspection apparatus is coupled.
Claim 2
Dependent Claim
85 words
An ultrasonic inspection apparatus comprising means for generating pulses of sonic energy; means for displaying variations in reflected sonic energy; and at least one transducer, said transducer being connected to said generating means, and said transducer being connected to said display means, said transducer occupying a portion of an arc of a circle and focused along a narrow line perpendicular to the plane of said circle through its center, and perpendicular to the surface of the test object to which the inspection apparatus is coupled.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 including a plurality of transducers, a first portion of the transducers being connected to said generating means for generating acoustical pulses of energy, and a second portion of the transducers being connected to the display means.
Claim 4
Dependent Claim
42 words
The apparatus of claim 2 where the first portion occupies a quadrant of the circle and the second portion occupies an adjacent quadrant, said first portion being electrically connected to each other and said second portion being electrically connected to each other.
Claim 5
Dependent Claim
28 words
The apparatus of claim 3 including a metallic block having an acoustic decoupling means situated in at least one surface thereof, said transducers being mounted on said surface.
Claim 6
Dependent Claim
40 words
The apparatus of claim 4 including a coupling means, the metallic block situated on one surface of said coupling means, and the other surface of said coupling means being shaped to fit a surface of the object to be tested.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5 including means or producing translational movement of said metallic block, said means being mounted on said coupling means.
Claim 8
Dependent Claim
68 words
An ultrasonic probe comprising: a plurality of transmitting transducers mounted on an arc of a circle and electrically commonly connected; a plurality of receiving transducers mounted on an adjacent arc of said circle and electrically commonly connected; said transducers being constructed to focus on a line perpendicular to said circle through its center, and perpendicular to the surface of the test object to which the probe is coupled.
Claim 9
Dependent Claim
68 words
An ultrasonic probe comprising: a plurality of transmitting transducers mounted on an arc of a circle and electrically commonly connected; a plurality of receiving transducers mounted on an adjacent arc of said circle and electrically commonly connected; said transducers being constructed to focus on a line perpendicular to said circle through its center, and perpendicular to the surface of the test object to which the probe is coupled.
Claim 10
Dependent Claim
38 words
