Siegfried, II, R W

This patent describes a borehole tool for generating signals indicating a condition of structure defining a borehole, including a rotatable transducer for transmitting and receiving signals relative to the structure. The improvement is characterized by: housing means for the tool; an elongated support member supported by the housing means; a support plate disposed on the support member and movable axially relative to the support member, the transducer being operably connected to the support plate for movement with the support plate axially relative to the support member; motor means connected to the support plate; and means engaged with the support member and operably connected to the transducer and the motor means for axially translating the transducer and rotating the transducer relative to the support member in timed relationship, one to the other, in response to operation of the motor means to provide a circumferential and axially extending transducer signal pattern along a portion of the borehole in which the tool is disposed.
