Abstract
Abstract A mounting system for mounting a transducer to a case, such that the transducer position is fixed and stable, and such that stresses on the transducer due to thermal expansion are minimized. The mounting system comprises a band, lower arms extending in a first axial direction from the band, and upper arms extending in a second, opposite axial direction from the band. The transducer arms are connected to the lower, and the upper arms to the case. In response to differential thermal expansion, the arms S bend in a radial direction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A mounting system for mounting a transducer to a support, the mounting system comprising: a band; a plurality of lower arms extending in a first direction from the band, the first direction being parallel to a longitudinal axis about which the band extends, each lower arm being relatively compliant for bending in a radial direction normal to the longitudinal axis and relatively noncompliant for bending in other directions; transducer attachment means spaced from the band in the first direction for permitting attachment of the transducer and the lower arms to one another; a plurality of upper arms extending in a second direction from the band, the second direction being opposite to the first direction, each upper arm being relatively compliant for bending in the radial direction and relatively noncompliant for bending in other directions; and support attachment means spaced from the band in the second direction for permitting attachment of the support and the upper arms to one another.
Claim 2
Dependent Claim
159 words
A mounting system for mounting a transducer to a support, the mounting system comprising: a band; a plurality of lower arms extending in a first direction from the band, the first direction being parallel to a longitudinal axis about which the band extends, each lower arm being relatively compliant for bending in a radial direction normal to the longitudinal axis and relatively noncompliant for bending in other directions; transducer attachment means spaced from the band in the first direction for permitting attachment of the transducer and the lower arms to one another; a plurality of upper arms extending in a second direction from the band, the second direction being opposite to the first direction, each upper arm being relatively compliant for bending in the radial direction and relatively noncompliant for bending in other directions; and support attachment means spaced from the band in the second direction for permitting attachment of the support and the upper arms to one another.
Claim 3
Dependent Claim
34 words
The mounting system of claim 1, wherein for each lower arm there is associated upper arm connected to the band at the same position around a circumference of the band as the lower arm.
Claim 4
Dependent Claim
20 words
The mounting system of claim 1, wherein the support attachment means comprises an outwardly extending flange on each upper arm.
Claim 5
Dependent Claim
57 words
The mounting system of claim 1, wherein the transducer attachment means comprises an inwardly extending flange on each lower arm. each inwardly extending flange including intersecting seating and positioning surfaces for mounting the transducer, the seating surface being parallel to said plane in which the band lies, and the positioning surface being parallel to the lower arm.
Claim 6
Dependent Claim
40 words
The mounting system of claim 1, wherein the transducer and support have different coefficients of thermal expansion, and wherein the band comprises a material having a coefficient of thermal expansion between that of the transducer and that of the support.
Claim 7
Dependent Claim
25 words
The mounting system of claim 1, wherein the band is dimensioned such that the transducer can be positioned within the band without contacting the band.
Claim 8
Dependent Claim
57 words
The mounting system of claim 6, wherein the transducer attachment means comprises an inwardly extending flange on each lower arm, each inwardly extending flange including intersecting seating and positioning surfaces for mounting the transducer, the seating surface being parallel to said plane in which the band lies, and the positioning surface being parallel to the lower arm.
Claim 9
Dependent Claim
58 words
The mounting system of claim 1, wherein each lower arm includes a distal end spaced from the band in the first direction, wherein the transducer attachment means comprises an inner surface of the distal end of each lower arm, and wherein the mounting system is dimensioned such that the transducer can be directly attached to said inner surfaces.
