Abstract: ABSTRACT OF THE DISCLOSURE        A thrust cancelling shaft coupling in which two generally axially disposed flanges are connected by two fructoconically shaped elements positioned in opposite rela-tionship to one another.  The large ends of both elements are connected to the flange on one shaft and both small ends are connected to the flange on the other shaft.  The thrust forces generated in one element as a result of a tendency to shorten in length under rotational and torque forces is counteracted by the corresponding forces in the other element so that thrust forces are not transmitted from the element to either the shafts, bearings or other parts of the driving and driven equipment. The larger end of each element is connected to the respective flange, with a sleeve-like member interposed between the larger ends of the elements, and the smaller ends of the elements are connected to a cylindrical member on the opposite flange. The two torsional elements, which are identical in size and shape, are constructed of elastomeric material and are capable of absorbing substantial angular and parallel misalignment between the drive and driven shafts.

Abstract: EXHAUST GAS RECIRCULATION CONTROL            ABSTRACT OF THE DISCLOSURE         A transducer regulates an operating pressure which positions an exhaust gas recirculation control valve pintle to provide exhaust gas recirculation at rates which maintain the pressure in the recirculation passage upstream of the valve pintle equal to a reference pressure; exhaust gas recirculation thus varies with engine exhaust backpressure and accordingly is substantially proportional to induction air flow.  The transducer has a pair of current carrying coils which create a bias affect-ing the reference pressure; the current is adjusted for selected operating conditions to change the reference pressure and thereby change the proportion of exhaust gas recirculation to induction air flow.

Abstract: A B S T R A C T     Reusable plastic container and plastic lid therefor, the lid being hermetically sealed to the container by a set adhesive.  The set adhesive has a greater attraction for the lid plastic than for the container plastic.  Such attraction is sufficient to ensure that, on removing the lid from the container, the adhesive is peeled from the container rim and removed with the reusable lid.  This leaves the container rim essentially free of adhesive to reduce the likelihood of contaminating the contained product with adhesive chemicals.  The lid or the container rim may be coated with the adhesive prior to heat-seal.  In the instance where the container is coated with the adhesive, the rim ledge portion may be provided with at least one continuous circumferentially extending raised portion to facilitate coating of the container rim.          Processes for manufacturing the adhesive-coated container lid and forming the container rim portion and applying adhesive thereto are disclosed.

Abstract: TEST CYCLE QUALITY CONTROL SYSTEM FOR AN             ELECTROPHOTOGRAPHIC MACHINE             Abstract of the Disclosure A system for checking copy quality variables within the image area of an electrophotographic machine.  During a test cycle, quality is checked by producing sample test areas within the photoconductor image area ordinarily used for producing copies.  Reflectance measurements are made on sample test areas and compared to a dynamically floating reference achieved by a reflectance measurement from a cleaned portion of the photoconductor within the image area.          The testing circuit is balanced so that the same reflectance voltage should be generated whether the single reflectivity-sensing device is viewing a sample test area or a cleaned reference area.  The system can be used to check for quality variables such as toner concentration, image voltage and an abnormally low reflectance photoconductor and provides a check on its own fault-free condition during periods when it is not in use.

Abstract: ABSTRACT     A quick disconnect assembly is disclosed for joining two members. The assembly is comprised of two circular steel bushings, a cylindrical steel pin and a steel spring ring. The bushings include axial circular openings and are each disposed in one of the legs of the first member so that they are axially aligned. The pin includes an annular groove in which is disposed the spring ring. The second member has a circular bearing at one end which has a circular opening extending axially therethrough.     Connection of the first and second members is accomplished by positioning the second member between the legs of the first member so that the bearing opening is in axial alignment with the bushing openings. The pin is then inserted into the three aligned openings from one end. Insertion is aided by chamfers which help to compress the spring ring. When the pin is fully inserted, the spring ring expands because of its resiliency and abuts against an annular shoulder in the opening of the first bushing to retain the pin in position.     Disconnection is accomplished by pulling the pin out of the openings. Pin removal in impeded by the annular shoulder. A second annular shoulder in the other bushing acts to retain the pin in a partially withdrawn position.

Abstract: Abstract of the Disclosure There is described a line isolation monitor for detecting ground faults in isolated power systems by determining the potential personnel hazard current due to the complex ground fault impedances and a method of accomplishing the same.  The total hazard current is determined by dividing the peak line voltage of the isolated power supply by the total impedance between ground and a common mode point, such as the center tap of the primary winding of the line isolation monitor transformer connected to the isolated power supply.  This impedance is determined at line frequency by impressing a minute, phase-modulated, power line frequency test signal into the isolated power system and using an extremely selective, coherent filter to remove the signals in phase with the power line signal.  The magnitude of the phase modulated test signal passed through the filter is related to the amount of fault impedance.  Comparison of this test signal magnitude to the line voltage provides an indication of the total hazard current.  The circuitry for accom-plishing this procedure includes a closed loop system which adjusts the current level of the test signal until the voltage of the filter test signal reaches a predetermined level related to the line voltage of the isolated system.  The current level of the test signal is then related to the total hazard current.

Abstract: ABSTRACT OF THE DISCLOSURE     A cover is provided for an electrical box, particularly when installed in an outside wall or in a ceiling, above which there is a cooler space.  The cover extends around all of the electrical box except the open face thereof andhas a flexible flange around its perimeter which contacts and seals against the back surface of the wall or ceiling in which the box is mounted.  The cover prevents cold air from entering the building through or around the box and heated air from escaping from the interior of the building which are disadvantages faced in electrical outlet box installations heretofore where no vapor barrier device is employed.  The cover also prevents water or moisture from entering the box from the outside.  The cover also can be specifically designed to receive particular shapes of electrical boxes including a plurality of boxes.  There are spacing means for varying the distance the open face of the box extends beyond the slanted flange so as to accommodate walls or ceilings of different thicknesses. These spacing means include a curved portion of the cover connecting the flange to the main portion of the cover 90 that the curved portion can collapse in a bellows-like fashion when the wall is urged against the flange.

Abstract: Abstract of the Disclosure A heading reference system mounted in a vehicle, e.g. an aircraft or a tank, includes a magnetic compass and a gyroscope.  The magnetic compass is subject to deviation in the magnetic field, hence the system must be calibrated.  If the vehicle is oriented in a starting direction, and the output of the magnetic compass compared to the output of the gyroscope, an error signal is developed.  This error signal is filtered to reduce noise, then stored.  The vehicle is then re-oriented and the procedure repeated until sufficient information is available to calibrate the system.  A micro-processor may be used for the computations and filtering of noise.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic continuous monitoring system for a chlorine dioxide generating process (10) which produces a gaseous mixture of chlorine dioxide and chlorine (12) is described.  The automatic system eliminates the need for periodic manual analysis of the off-gas stream and enables changes in the process efficiency to be rapidly compensated for.  The system preferably utilizes a gas-liquid chromatograph analyzer (36) to analyze the off-gases from the generator (10) and to provide signals (42, 44) corresponding to the measured amounts of chlorine dioxide and chlorine.  These signals then are converted (46) to a signal (47) corresponding to the ratio of chlorine dioxide and chlorine in the off-gas stream.  The ratio then is converted to the efficiency (48).  The efficiency value so obtained (49) may be compared with a previously determined value and changes compensated for by catalyst and/or reactant feed variations.
