Apparatus and method employing foam sleeves for supporting magnetic sensors in a tubular housing
First Claim
1. Apparatus for supporting magnetic sensors in a tubular housing, comprising an elongated support adapted to have magnetic sensors mounted thereon, a resiliently compressible sleeve through which said support extends, and attachment means securing the sleeve to the support at a leading end portion of the sleeve, the sleeve being tapered so that it is narrower at the leading end portion than at a trailing portion, whereby the elongated support may be inserted in the tubular housing axially, with the leading end portion of the sleeve entering the housing before the trailing portion, and the sleeve may engage the inner surface of the housing to shock mount the support in the housing and to resist movement of the support in the housing in a direction opposite to the insertion direction.

Abstract
A magnetic sensor assembly including an elongated support is supported in a tubular housing by a pair of tapered foam sleeves that space the support from the inner surface of the housing and that resist movement of the assembly in the housing in a direction opposite to the direction of insertion of the assembly into the housing. The sleeves, which are either continuous hollow cylinders or are formed of wound strips, are attached to the support by adhesive tape at the leading end of each sleeve.

- 6. Magnetic detector apparatus comprising a non-magnetic tubular housing, an elongated magnetic sensor support in said housing extending axially of the housing, and a pair of spaced sleeves surrounding the sensor support and spacing the sensor support from the inner surface of the housing, each sleeve being formed of resiliently compressible material and having its leading end portion secured to the support by attachment means so that the sleeve may be pulled into the housing from its leading end portion.
- 10. A method of supporting a magnetic sensor assembly in a tubular housing, which comprises providing a pair of spaced foam sleeves surrounding an elongated support on which magnetic sensors are mounted, attaching only the leading end portion of each sleeve to the support by wrapping adhesive tape about the leading end portion and the support, and inserting the assembly including the sensors, the support and the sleeves axially into the housing so that the leading end portion of each sleeve enters the housing before a trailing portion of each sleeve and so that the sleeves engage the inner surface of the housing.
