Abstract
Abstract A mechanical transducer probe assembly is provided which is both rugged and easy to assembly. The probe mechanism is located inside a hollow probe case. A reference point for assembly is located on the inner surface of the case. A motor assembly and a transducer mounting assembly are located within the case and are fixedly joined together. At the jointure of the two, the motor and transducer assemblies are in contact with the reference point, thereby positionally locating the transducer and its drive mechanism within the case. Means are provided for urging the motor and transducer assemblies against the references point, which means also provides shock mounting for the probe mechanism.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
An ultrasonic transducer probe, in which a drive mechanism is used to oscillate an ultrasonic transducer, comprising: a hollow probe case, including a reference indicator on the inner surface thereof, for containing elements of said probe; a motor assembly, located in said case, and having a forward end; a transducer assembly, located in said case and including means for mounting said ultrasonic transducer for oscillation, and having a rearward end; and means for connecting said motor assembly to said transducer assembly at a jointure of said forward and rearward ends, said jointure being fixedly positioned by said connecting means in reference to said reference indicator.
Claim 2
Dependent Claim
105 words
An ultrasonic transducer probe, in which a drive mechanism is used to oscillate an ultrasonic transducer, comprising: a hollow probe case, including a reference indicator on the inner surface thereof, for containing elements of said probe; a motor assembly, located in said case, and having a forward end; a transducer assembly, located in said case and including means for mounting said ultrasonic transducer for oscillation, and having a rearward end; and means for connecting said motor assembly to said transducer assembly at a jointure of said forward and rearward ends, said jointure being fixedly positioned by said connecting means in reference to said reference indicator.
Claim 3
Dependent Claim
22 words
The ultrasonic transducer probe of Claim 1, further comprising means for urging said motor assembly and transducer assembly against said reference indicator.
Claim 4
Dependent Claim
40 words
3 . The ultrasonic transducer probe of Claim 1 or Claim 2, further comprising a snap ring, located in said probe case in contact with said reference indicator, wherein said snap ring is sandwiched by said forward and rearward ends.
Claim 5
Dependent Claim
28 words
The ultrasonic transducer probe of Claim 3, wherein said reference indicator comprises a groove in the inner surface of said probe case, and said connecting means includes screws.
Claim 6
Dependent Claim
25 words
The ultrasonic transducer probe of any one of claims 1 to 4, wherein said transducer assembly includes a gimbal cup for pivotally mounting said transducer.
Claim 7
Dependent Claim
28 words
The ultrasonic transducer probe of Claim 5, wherein said transducer assembly includes a ring for holding said transducer, said ring and transducer being snap-fit into said qimbal cup.
Claim 8
Dependent Claim
47 words
The ultrasonic transducer probe of Claim 2 or any claim dependent thereon, wherein said motor further has a rearward end, and said urging means includes a spring located at said rearward end of said motor for urging said forward end of said motor against said reference indicator.
Claim 9
Dependent Claim
30 words
The ultrasonic transducer probe of Claim 7, wherein said reference indicator includes a groove in the inner surface of said hollow case, and a snap ring located in said groove.
Claim 10
Dependent Claim
34 words
The ultrasonic transducer probe of Claim 8, further including a spacer located between said rearward end of said motor and an inner surface of said probe for effecting a desired compression of said spring.
