Abstract
Abstract A sensing device which defines the terminal position and inclination of a curved prospect hole drilled from a passage in a mine by indicating the distance, slope and deflection, from initial position and azimuth, of progessive points along the hole. An in-hole sensor is provided with a plurality of potentiometers mounted on mutually perpendicular axes to which are attached pendulums. Angular changes in inclination and attitude of the sensor with reference to the pendulum''s vertical position cause related electrical outputs from the potentiometers which can be read as degrees by a readout instrument. Other potentiometers therein have their electrical outputs altered to an extent proportional to the deflection of the hole. According to the method of the invention cross section samples may be taken from the ground surrounding and in the plane of mine workings by drilling curved prospect holes from within existing mine openings.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A probe assembly for determining the direction and extent of a bore in the earth including: a. a guided sensing device adapted to pass through a bore hole in the earth, said sensing device having a generally cylindrical casing; b. a rod, coaxial of said Sensing device, and positioned and carried at one end thereof, to thereby define with said sensing device two coaxial members bendable with respect to each other; c. said rod carrying a deflection shaft, one end of which extends into the adjacent end of the sensing device; d. a deflection transducer carried within said sensing device, said transducer having an actuating arm, said arm being in abutting contact with and actuated by said deflection shaft; and e. a pair of pendulums carried within said sensing device, each of which is coupled to and actuates its own separate transducer, the axes of rotation of said pendulum being mutually perpendicular, each transducer being fixed relative to and carried within said sensing device, whereby changes in orientation of the sensing device cause movement of the pendulums relative to their associated transducers to thereby actuate them.
Claim 2
