Abstract: Abstract Throttle Linkage Structure And Method For Its Assembly And Disassembly A flexible cable connected at one end to a throttle lever (not shown) is displaceable in a telescoping manner relative to a protective sheath and is pivotally connected at its second end to a connecting lever.  The connecting lever and a portion of the flexible cable reside within a housing which is attachable to a mounting member.  The connecting lever has splines which are circumferentially engageable with a splined governor shaft which protrudes from the side of the member and extends into the housing through an opening.  A cover is attachable to the housing in closely spaced axial relationship with the connecting lever so as to prevent its disengagement from the governor shaft.  The connecting lever extends into the opening to insure access to the connecting lever when it is disengaged from the shaft.  The flexible cable has two extreme displacement limits (E,F) which correspond to two extreme rotative limits (E,F) for the shaft.  Method and apparatus are provided for maintaining the calibration and correspondence between the cable's displacement limits (E,F) and the shaft's rotative limits (E,F) when the connecting lever is disassembled and reassembled with the governor shaft.

Abstract: SECONDARY FIELD DIELECTRIC CONSTANT   WELL LOGGING SYSTEM AND METHOD         (D#77, 934-F) ABSTRACT     Apparatus  for  determining  the  dielectric  constant and/or conductivity of earth formations traversed by a borehole includes a transmitter which transmits electromagnetic energy into the earth formation from a first location in the borehole at a  frequency which enables the electromagnetic energy to propagate   throughout   the   surrounding   earth   formations.          Receivers receive electromagnetic energy at two locations in the  borehole  which  are  spaced  longitudinally  from  the transmitter  provide  signals  representative  of  the  total electromagnetic fields at the receiver locations.   Circuitry determines the dielectric constant and/or resistivity of the formations in accordance with a secondary field ratio and a phase  difference  derived  from  the  signals  provided by  the receiving means.

Abstract: LOW NOISE VALVE  Abstract of the Disclosure A low-noise valve has a body with a fluid inlet to receive pressurized fluid, an outlet and a fluid passageway extending between the inlet and outlet.  Located in the passageway are a number of spaced throats.  The valve also includes a movable stem with a number of plugs each adapted to be closely received by a corresponding throat.  Each plug includes a plurality of circumferential alternating grooves and lands, the lands being closely spaced within the throats to create a plurality of flow restrictions each incrementally restricting fluid flow when the stem is at a minimum flow position.  Movement of the stem toward a full open position sequentially removes the lands from the throat to reduce restriction of such fluid flow in stages.

Abstract: A B S T R A C T      A method of determining the depth of the molten electrolyte layer in an aluminium electrolytic reduction cell, and using the measurement to control the operation of the cell, is based on the fact that when an anode is raised, the current passing through it drops to zero when the anode carbon face loses physical contact with the molten electrolyte.   The method involves raising the anode and noting the distance travelled before the current falls to a predetermined fraction of its initial value.   The method is well adapted to automatic control of electrolyte depth.

Abstract: Abstract Of The Disclosure The polarized potential at the boundary between a submerged pipe and a medium is measured unaffected by the presence of a distributed IR drop in the medium due to a impressed current from a corrosion protection system.  The voltage between the pipe and a reference electrode in the medium is measured when the protection system current is zero.  This is accomplished with a sample-and-hold circuit controlled by a trigger signal derived from the input signal and having a variable phase for controlling the phase angle at which the sample is taken.

Abstract: RING LASER GYROSCOPE CURVED BLADE FLEXURE        AND SUPPORT RING ASSEMBLY AND METHOD               Abstract of the Disclosure A dither flexure for a ring laser gyroscope includes a central portion and a plurality of curved vanes extending therefrom to connect to a flexure ring. The flexure ring includes a boss in a central portion thereof. A glass ceramic ring having a pair of end bosses is bonded to the boss around the flexure ring with the end bosses facing outward toward the ring laser gyroscope frame. The end bosses contact the ring laser gyroscope frame so that a void is formed opposite the flexure ring boss, which prevents transmission of radially directed stresses from the dither flexure to the frame. The curved blades have high resistance to off-axis vibrations and have high off-axis resonant frequencies so that very little coning and axis sag occur. Each blade has a curved portion and a straight portion, which provides a convenient location for mounting piezoelectric drive elements for dithering the ring laser gyroscope.
