The master controller comprises a first flow sensor producing  a first flow variable signal in response to a sensed flow in the duct section asso-ciated with the said one damper.  An adjustable reference or bias signal generator is provided and a temperature signal is com-bined therewith to provide a composite signal for comparison with the flow variable signal.  A resultant signal after comparison operates the first pneumatic actuator for the said one damper. tracking controller comprises a second flow sensor producing a second flow variable signal in response to sensed flow in the duct section associated with the other damper.  A second signal comparitor and transmittor receives the first and second flow variable signals, compares the two and transmits a second re-sultant signal to the second pneumatic actuator for control of the said other damper.  The second comparitor includes a pivot-ally mounted lever acted upon by diaphragm actuated first and second push rods representing the first and second flow variable signals.  One of the diaphragm assemblies is mounted for slid-able adjustment along the lever to vary the relative mechanical advantage and to vary the flow ratio between the two dampers and duct sections.  The described system overcomes the limitations of the prior art by allowing for more accurate and co-ordinated flow rates in both duct sections.

Abstract: ABSTRACT          A method and apparatus are described for performing X-ray fluorescence (XRF) analysis where the physical relationship between the source/detector and the object being examined is not controlled.  This technique and apparatus is particularly advantageous in performing an in situ analysis of the concentration of one or more elements present in a matrix of a material such as rock. In accordance with this aspect of our invention, such a mineral assay is performed by drilling a borehole into the matrix, inserting into the borehole a probe containing a suitable XRF source/detector, irradiating the matrix, detecting the spectrum of radiation that is produced and analyzing this spectrum.  Preferably, the concentration of the assayed element is determined from the following formula:                                    where S is the number of photons counted having energies in a signal range where the X-ray spectral line of the assayed element is observed, C is the number of photons counted in a range where a radiation peak is observed, B is the number of photons counted in a background range, E is the number of photons counted in a range adjacent that where said radiation peak is observed, and K1 through K6 are empirically determined constants relating to the performance of the probe.

Abstract: ABSTRACT OF THE DISCLOSURE          Method  and  apparatus  for  removing  oil  and  other organic constituents from particulate, inorganic-rich mineral solids.  The method and apparatus are particularly suitable for removing oil from oil-contaminated drill cuttings.  The solids to be treated are transferred  into pressure vessel means wherein they are contacted with an extractant which is normally  a  gas  but  is  under  conditions  of  pressure  and temperature to provide the extractant in a fluidic solvent state  for  the  constituents  to be  removed,  whereby  the constituents  are  transferred  to  the  extractant.  The extractant containing the constituents is withdrawn from the pressure vessel and depressurized to render it a nonsolvent for the constituents and to form a two-phase system which can then be  separated  into  extractant  for  repressurizing  and recycling with proper handling of the constituents removed. In  the  case  of  removing  oil  from  drill  cuttings,  the essentially  oil-free  cuttings  can  be  disposed  of  in  any suitable manner including dumping overboard from an offshore drilling rig.

Abstract: MODULAR SCREW ANCHOR HAVING LEAD POINT     NON-INTEGRAL WITH HELIX PLATE            Abstract of the Disclosure A high strength, modular screw anchor is disclosed which exhibits enhanced failure resistance notwithstanding use of essentially the same amount of material as conventional anchors, and which can be installed using existing installation equipment.  The preferred screw anchors of the invention include an elongated rod having one or more separate, specialized anchor members supported thereon, and an improved, obliquely oriented, beveled earth-penetrating lead to facilitate installation, particularly in rocky soils.  The anchor member includes a tubular, central, rod-receiving hub presenting a polygonal in cross-section bore therethrough, and an outwardly extending helical blade affixed to and coaxial with the hub.  In installation procedures the anchor rod is passed through the hub bore and the anchor member is operably coupled to the rod (as by resting it atop an outwardly extending shoulder provided on the rod); the tubular shank of a standard anchor wrench is next telescoped over the anchor rod and inserted into the hub bore such that a driving connection is established between the rod, shank and anchor member.  Axial rotation of the wrench thus effects corresponding rotation of the screw anchor for installation purposes.  The earth-penetrating lead of the screw anchor may be formed integrally with the major portion of the rod, or threaded thereon; in the latter case the overall length of the rod can be adjusted as desired.  The (Docket No. 16993) modular nature of the screw anchors hereof permits stocking of only a relatively few standard compo-nents which can be used as needed in the field to achieve a desired anchor configuration.

Filed: 1982-10-28
Granted: 1986-03-18
Abstract: Abstract Apparatus for randomly offsetting the frequencies of each transmitter in a simulcast radio communications system is described. The random frequency offsetting apparatus includes a random noise source for generating a noise signal which is amplified and low-pass filtered before application separately or in combination with an information signal to the frequency modulation input of a corresponding transmitter. In frequency modulated systems, the noise signal and information signal are combined and modulated onto the transmitters; whereas, in envelope modulated systems, the noise signal is frequency modulated onto the transmitter, and the information signal is envelope modulated onto the transmitter. Since the frequency of each simulcasting transmitter is randomly varying, deep cancellation nulls created in the overlap areas between transmitters by multi-transmitter interference will be randomly distributed in randomly varying locations. Therefore, communications between a central station and remote stations located in the overlap areas will not be interrupted by the nulls for long periods of time, as was possible in prior art simulcast systems.
