Title: Electronic ground detector for armature  supplies
Inventor: YOUNG JOHN A I
IPC: G01R31/34
Filed: 1979-03-23
Granted: 1982-01-12
Abstract: ELECTRONIC GROUND DETECTOR FOR ARMATURE SUPPLIES              ABSTRACT OF THE DISCLOSURE This invention relates to a ground fault detector for a d.c. machine having a convertor power source.  The detector includes a resistance circuit device that detects unbalanced currents corresponding to an asymmetrical ground fault in the machine.  An undesired common mode voltage from the convertor is also present.  A ground sensor connected to a mid-point of the resistance circuit filters out the harmonic voltage so that the ground sensor produces at its output a fault signal whose magnitude represents the ground fault current.  The detector also includes a terminal sensor for sensing the convertor output voltage and for providing a terminal output signal proportional thereto.  An attenuator attenuates this output signal by a predetermined amount which results in a threshold signal.  Both the fault signal and threshold signal vary as the convertor output voltage varies.  However, a trip signal is generated when the magnitude of the fault signal exceeds the magnitude of the threshold signal.  The trip signal is independent of variations in convertor output voltage.  Previous ground fault detectors have been desensitized by harmonic voltages from the convertor which resulted in false ground fault readings.  The present detector filters out the harmonic voltages and is independent of variations in convertor output voltage.

Abstract: Case 3736 TITLE:   COKE DESULPHURIZATION          Abstract of the Disclosure Coke is desulphurized by sequentially heating the coke to desulphurization temperatures, and maintaining the coke at desulphurization temperatures to effect desulphuriza-tion thereof, the coke reaching a temperature of at least 1000°C (preferably at least 1100°C and, most preferably at least 1200°C) during desulphurization.  Cooling and all or a portion of the heating is effected by direct counter-current contact with a gas, with the heat released from the coke during cooling being recuperated by the gas and employed to provide most of the heating to bring the coke to desulphurization temperature.  The coke and/or the gas are heated between the cooling and heating steps to maintain the gas at a temperature below that of the coke dur-ing cooling and at a temperature above that of the coke during heating.  The gas for the cooling and heating is a recycle gas, recovered from the direct contact heating to the direct contact cooling.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a hot tip seal located between the nozzle and the gate in an injection molding system.          The seal has a generally cylindrical hollow outer portion which is seated in the nozzle and extends to abut on the cavity plate around the gate.  Three ribs extend radially from the outer portion to an elongated central pin portion and define apertures therebetween.  Pressurized melt flows from a central passage in the nozzle, through the apertures around the central pin portion, and into the cavity.  The nozzle seal prevents direct contact between the heated nozzle and the cooled cavity plate to reduce heat loss, while at the same time improves heat transfer to the gate area by conducting heat downstream to a tip of the central pin portion which extends into the gate.  In one embodiment, the central pin portion is enlarged and formed of a more conductive material to improve this process.

Abstract: PHD 79-109                                        26.06.1980 ABSTRACT.            Method for examining a body with penetrating radiation.    Devices that measure the electron density in a body by means of radiation scattered from a narrow pencil beam of penetrating radiation directed through the body, produce defective images on reconstruction of the density distribution because of multiple scattering of radiation. This can of course be reduced by scattered ray diaphragms, but cannot be eliminated entirely. The invention therefore provides a means for detecting the size of the multiple scattered radiation component by measurement. For this purpose, the detector array which measures radiation including the single scattered radiation, is screened, at least occasionally, from the single scattered radiation and the detected intensity values measured by the detector elements when so screened, are used to correct the values generated by measuring the detected radiation including the single scattered radiation.

Abstract: FLUID SIGNAL TRANSMITTING APPARATUS        Abstract Of The Invention A fluid signal inverting unit includes a motion balance unit having a lever which operates a valve.  The balance lever is supported at the opposite ends by a pilot signal chamber and a feedback signal chamber and an intermediate pivot support is coupled to position a back pressure leakport valve.  Each chamber includes an outer matched linear metal diaphragm fixedly connected to the aligned end of the lever.  Increases in pilot pressure result in the outward movement of the linear diaphragm and corresponding outward and pivotal movement of the lever.  The lever tends to move away from and open the valve resulting in a decrease in the output pressure and an inverted output pressure signal which may be further amplified and transmitted to a flow booster relay, and as negative feedback signal to the feedback chamber.  Decrease in pilot pressure results in an opposite action and an increase output pressure.
