Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A device for use in geophysical exploration of earth formations traversed by a borehole, comprising: sensor means having detecting means for detecting seismic acoustic data and having a clamping means for clamping the sensor means to a wall of a borehole; carrier means for carrying the sensor means, the carrier means defined by a front end block, a rear end block spaced from the front end block, and a pair of side blocks extending in parallel between the front and rear end blocks, the front end block being adapted for connection to a first point of a cable and the rear block being adapted for connection to a second point of the cable, and at least one of the pairs of side blocks being formed with a conduit passage for receiving conductors of the cable; and damping means, comprising two O-rings interposed between the sensor means and the carrier means, for acoustically isolating the carrier means from the sensor means when the sensor means is clamped to the wall of the borehole.
Claim 2
Independent Claim
172 words
A device for use in geophysical exploration of earth formations traversed by a borehole, comprising: sensor means having detecting means for detecting seismic acoustic data and having a clamping means for clamping the sensor means to a wall of a borehole; carrier means for carrying the sensor means, the carrier means defined by a front end block, a rear end block spaced from the front end block, and a pair of side blocks extending in parallel between the front and rear end blocks, the front end block being adapted for connection to a first point of a cable and the rear block being adapted for connection to a second point of the cable, and at least one of the pairs of side blocks being formed with a conduit passage for receiving conductors of the cable; and damping means, comprising two O-rings interposed between the sensor means and the carrier means, for acoustically isolating the carrier means from the sensor means when the sensor means is clamped to the wall of the borehole.
Claim 3
Dependent Claim
32 words
The device of claim 1, wherein the two O-rings are respectively mounted on the front end block and the rear end block to acoustically isolate the carrier means from the sensor means.
Claim 4
Dependent Claim
19 words
The device of claim 2, the sensor means having seats at opposite ends for respectively receiving the two O-rings.
Claim 5
Dependent Claim
23 words
The device of claim 3, the front end block and the rear end block each having shoulders that respectively abut the two O-rings.
Claim 6
Independent Claim
93 words
A device for use in geophysical exploration of earth formations traversed by a borehole, comprising: sensor means having detecting means for detecting seismic acoustic data and having a magnetic clamping means for clamping the sensor means to a wall of a borehole; carrier means for carrying the sensor means and adapted for connection to a cable; damping means comprising two O-rings interposed between the sensor means and the carrier means for substantially acoustically isolating the carrier means from the sensor means when the sensor means is clamped to the wall of the borehole.
Claim 7
Independent Claim
93 words
A device for use in geophysical exploration of earth formations traversed by a borehole, comprising: sensor means having detecting means for detecting seismic acoustic data and having a magnetic clamping means for clamping the sensor means to a wall of a borehole; carrier means for carrying the sensor means and adapted for connection to a cable; damping means comprising two O-rings interposed between the sensor means and the carrier means for substantially acoustically isolating the carrier means from the sensor means when the sensor means is clamped to the wall of the borehole.
Claim 8
Dependent Claim
19 words
The device of claim 5, the sensor means having seats at opposite ends for respectively receiving the two O-rings.
Claim 9
Dependent Claim
19 words
The device of claim 6, the carrier means having shoulders at opposite ends for respectively abutting the two O-rings.
