Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus are disclosed for investigating lateral characteristics of an earth formation penetrated by a borehole.  Substantially identical measurement transducers are mounted in a fixed separation, side-by-side relationship on a pad adapted for sidewall application.  As a pad traverses the borehole, measurement signals are produced corresponding to the same formation investigation conducted along two side-by-side paths on the borehole wall.  The signals are recorded and provide an indication of lateral changes between the side-by-side paths.  By comparing the signals with varying depth displacements, the best likeness and corresponding displacement are determined and provided as an indication of lateral inclination of the formation.  The best likeness indicates a lateral formation homogeneity characteristic and the displacement the inclination of the lateral characteristic between the side-by-side paths.  In a multipad embodiment, the lateral characteristic determination is made for each pair of side-by-side paths around the borehole and combined to provide the dip of lateral characteristics which persist to some degree around the borehole.  When side-by-side transducer pads are employed on conventional dipmeters, twice as many dipmeter signals are produced, allowing more detailed correlation of signal features corresponding to vertical changes in formation characteristics, such as occur between bed boundaries, and thus improves the formation dip determination.

Abstract: ABSTRACT OF THE DISCLOSURE A magnetic flowmeter utilizes a field coil having a portion extend-ing generally along the longitudinal axis of a flow conduit to generate an integral magnetic field therein, concentrically located about the field coil and perpendicular to the flow.  An inner electrode surrounds the longitudinal portion of the coil, and the conduit itself is used as the other electrode across which flow induced voltages are sensed, thereby providing a large surface-area electrode.  The magnetic field excitation is accomplished by high current (over 20 amperes), very short duration (less than 10 millisecond) pulses.  The inductance of the field coil windings is of low enough value to establish very rapid (less than 2 millisecond) rise and decay time constants so that electrode output voltages may be read within a correspondingly short period of time after the field current pulse is turned on.  These electrode voltages are comprised of two components, i.e., a short-pulse, flow induced signal proportional to flow rate superimposed on a d-c voltage that is approximately equal to the galvanic potential at the electrodes.  In a pre-ferred embodiment, a pulse transformer, connected in the signal path between the sensing electrodes and the readout circuitry, passes the flow induced component, while at the same time isolating the d-c component, thereby pro-ducing at its output a signal representing the actual flow signal.  In an alternate embodiment, two voltage readings are sampled, one when the magnetic field is at steady-state on value, the other after the field current is turned off, and then subtracted to produce the actual flow signal.  Since these two readings are made within a few milliseconds of one another, no additional circuitry is required to compensate for any drift in the baseline galvanic d-c voltages.

Abstract: VARIABLE DIAMETER TORQUE SENSING DEVICE                ABSTRACT OF THE DISCLOSURE         A load responsive torque sensing unit adapted to drive the rotor of an axial flow combine and including a variable pitch V-belt input sheave, and an output shaft concentric therewith, the latter having means for connecting it drivingly to the combine rotor.  The input sheave consists of a pair of sheave sections, one of which is axially fixed on the output shaft in direct driving relationship, and the other of which is axially slidable, but freely rotatable, relative to the output shaft toward and away from the fixed section for V-belt reception therebetween.  A compression spring yieldingly biases the shiftable section toward the fixed section, while a cam on the shiftable section cooperates with a pair of cam followers which rotate in unison with the fixed section and shaft in such a manner that an increase in the load on the output shaft will cause the cam to ride on the followers and force the slidable section toward the fixed section, thus increasing the side forces acting on the V-belt to prevent belt slippage, thereby tensioning the belt only insofar as is required to transmit the necessary torque for output shaft driving purposes.  The unit is designed for cooperation with a special draw bolt arrangement which facilitates dismantling of the unit.
