Abstract: ABSTRACT     A new induction motor control method and system utilizes one or more electric power inverters each supplying a separate induction motor with alternating current excitation power. The respective inverters pre-ferably comprise auto-sequential commutated controlled current inverters.       Direct current is supplied to each inverter in the system from a common direct current power supply preferably comprising a phase controlled rec-tifier circuit with individual current smoothing inductors connected in the direct current link to each power inverter for isolation purposes. A com-mon operator controlled power level control module is provided for con-trolling the magnitude of the output current supplied from the common phase controlled rectifier to all of the inverters in parallel. Respective motor flux sensing means are provided for each induction motor for de-riving individual feedback control signals representative of the flux de-veloped by the respective induction motors. The flux feedback signal is summed with an input command value of a flux control signal in a suitable summing circuit, and the error signal is supplied through a suitable com-pensating circuit for regulating the flux level of the respective induction motors by individually controlling the frequency of the excitation current supplied to the stator windings of the motor by its associated inverter. In a preferred embodiment the actual electro-magnetic flux produced across the induction motor stator-rotor gap is sensed and fed back to the summing circuit for control purposes. This sensed actual value of motor flux signal also is utilized to derive an actual value of torque feedback control signal that is employed in controlling the magnitude of the direct current supplied by the common phase controlled rectifier to all of the inverters in parallel.     It is also preferred to employ a phase lock-loop converter as the compensating circuit in the frequency control.

Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for producing starch and gluten from wheat, rye or barley.  The invention uses a conventional break system but the reduction system is modified to comprise three groups, namely a sizing group having pairs of fluted rolls for semolina reduction, the speed ratio of the sizing group pairs of rolls being between 1:1.3 and 1:1.8.  A pressing and impacting group follows the sizing group and is provided with pairs of smooth rolls whose speed ratio is in the range of 1:1 and 1:1.2. This group further includes an impact detacher or a beater detacher arranged between each pair of smooth rolls and its associated screening unit.  The third group is a final reduction group whose stages are provided with pairs of smooth rolls or fine fluted rolls having speed ratio between 1:1.2 and 1:1.4.  The final reduction group may also be provided with impact or beater detachers at each of the passage of the final group.  The method and apparatus results in virtually no losses in dry substance, at the same time achieving a reduced water consumption.  There is a higher yield in gluten as compared with the known methods.  The purity and quality of the obtained gluten is considerably better than obtained in prior art method and apparatus.

Abstract: LEAD-LAG, SERIES-SEQUENCE STARTING  AND OPERATING APPARATUS FOR THREE     TO SIX FLUORESCENT LAMPS     ABSTRACT OF THE DISCLOSURE      Lead-lag, series-sequence starting and operating apparatus for three to six fluorescent lamps comprises two parallel circuit branches, one of which comprises a ballast capacitor and two lamps in series for a three or four lamp apparatus or three lamps in series for a five or six lamp apparatus.  The other circuit branch comprises an inductor ballast and one or two lamps in series for a three or four lamp apparatus and two or three lamps in series for a five or six lamp apparatus.  An additional ballast inductor con-nects in series with the two parallel-connected circuits and the AC power source.  Starting capacitors parallel individual lamps and means are provided for preheating the lamp elec-trode coils upon energization of the apparatus.  In operation, the lamp electrode coils are all preheated and the lamps which are ballasted by the capacitor, which constitutes the lead circuit, then sequentially start.  The ballast capacitor and the additional ballast inductor constitute a circuit which is at least partially resonant at the line frequency and the resulting increased potential drop across the operat-ing lead circuit sequentially initiates the discharge in the lamps which are in series with the first inductor, which constitutes the lag circuit.  When all lamps are operating, the electrode coil heating potential is decreased to mini-mize power losses,  For a four lamp circuit, the cost of the apparatus is considerably less than the cost of two two-lamp rapid start ballasts which are presently used for most installations, and the power losses in the present ballast are also considerably reduced.

Abstract: ABSTRACT OF THE DISCLOSURE: Hydrochloric acid having a substantially constant HCl content of 20 to 36% is produced continuously by removing hydrogen chloride form hot combustion gas. To this end, hot combustion gas containing 1 to 10 % by volume of HCl and steam, this gas being obtained by the joint combustion of off-gases containing chlorinated hydrocarbons and liquid residues of chlorinated hy-drocarbons, is introduced into a quenching zone, and quenched therein, down to a temperature lower than its dew point, by means of cooled hydrochloric acid con-taining hydrogen chloride in a concentration of 20 to 36 %, which concentration corresponds to the concen-tration of the hydrochloric acid which is to be produced. The resulting gas-liquid mixture is separated in an absorption cooling zone into cooled hydrochloric acid and cooled combustion gas containing 0.1 to 1 % by volume of HCl.  The cooled hydrochloric acid is introduced into a reservoir zone capable of receiving a multiple of the quantity of hydrochloric acid produced per hour, and recycled from the said reservoir zone to the quenching zone. Additional 20 to 36 % hydrochloric acid produced is taken out of the quenching cycle.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a digital communication system of the type transmitting data on a plurality of modulated frequency-diversity-multiplex carriers interspersed between harmonics of a system-wide signal and utilizing a main synchronized detector at a receiving end.  The system is immunized to signal degradation due to reception of "noise" from the shifting of both signal harmonics and the modulation sidebands of adjacent carriers into the passband of the desired communication signal.  The methods used for interference minimization includes: emplacing each data carrier at a frequency mid-way between adjacent harmonics of the system-wide signal, locking the frequency of the data carrier to the system-wide signal frequency to maintain the data carrier fre-quency exactly mid-way between two adjacent harmonics of the system-wide signal, transmitting the data in digital form and modulating each data carrier at a baud rate essentially equal to an exact even submultiple of the frequency of the system-wide potentially-interfering signal, and detecting the transmitted digitally-modulated carrier at the receiving end by use of long-time-constant bandpass filters.  The main synchronized data detector uses integrating filters which discharge their storage elements after each baud time period, as determined by a baud clock synchronized with the system-wide signal.

Abstract: ALTERNATING CURRENT POWER     GENERATING SYSTEM          ABSTRACT OF THE DISCLOSURE A system for generating alternating current of selected voltage at a target frequency includes a plurality of A.C. generators, at least one of which has a rotatably mounted stator.  A prime mover drives a power input shaft at speeds extending through a wide range and the shaft is connected to the first rotor.  As speed increases, the gener-ator reaches the desired frequency and a sensing device re-leases the stator to rotate and maintain a relative speed between itself and the rotor corresponding to the target frequency.  The stator drives the second rotor at its own absolute speed which is the difference between the power input shaft speed and the relative speed between the first stator and rotor.  A field control maintains the desired voltage and a load control trans-mits the current output to a load and varies the load to maintain the generator at proper operating condition.
