Abstract: ASYMMETRIC ERASE ACROSS A ROTARY         TRANSFORMER TO A ROTATING MAGNETIC HEAD          ABSTRACT OF THE DISCLOSURE         The equivalent of D.C. erase in magnetic tape using a rotating head is accomplished by trans-mitting a time asymmetric square wave across a rotary transformer to the rotating head.  The time asymmetry of the square wave in combination with passage of the square waveform across the rotary transformer creates in the rotating head an erase current asymmetric in amplitude about an average value.  The short interval of the square wave has a large amplitude in one direction and the long interval portion of the square wave has a short amplitude in the opposite direction.  This current signal in the head produces alternately a large flux bubble above the head and a small flux bubble above the head.  By maintaining the relative head to tape speed such that the large flux bubble always overlaps the small flux bubble, the tape can be D.C. erased by an asymmetric waveform.  A double-ended driving circuit and a single-ended driving circuit are shown for driving across a rotary transformer to the rotating head with the asymmetric waveform.

Abstract: ABSTRACT      An improved method is utilized to make a mold for a cast product having a plurality of spaced apart surfaces.  Although the method could be used for forming molds for different pro-ducts, the method is advantageously used to form a mold for a cast product having a plurality of airfoils disposed in a circular array.  To form the mold, a plurality of airfoil pattern segments are placed in a circular array with surfaces of the segments abutting at joints which are free of material interconnecting the segments.  A coating of liquid ceramic mold material is applied over the airfoil pattern segments.          Since the joints between the airfoil pattern segments are free of interconnecting material, the liquid ceramic mold material can flow into the joints.  After the ceramic mold material has been dried and the airfoil pattern segments disposed of, the ceramic mold material which entered the joints between the airfoil pattern segments forms a plurality of relatively thin projections from the main wall of the mold.  These thin pro-jections are broken away before the product is cast in the mold.          During the application of the ceramic coating to the airfoil pattern segments, the relatively flexible wax airfoil pattern segments are advantageously supported by a relatively rigid annular pattern member which is disposed outwardly of the airfoil segments.

Abstract: ABSTRACT OF THE DISCLOSURE     Phosphate rock and sulfuric acid are reacted under conditions which result in the formation of calcium sulfate hemihydrate and phosphoric acid of about 35% to about 55% P205.  A two vessel reaction system maybe used in which the reaction slurry undergoes inter and intra- vessel circulation. The solution portion of the slurry in the first vessel (the "dissolver") is preferably maintained at a negative sulfate concentration (i.e. excess Ca+2) and the solution in the second vessel (the "crystallizer") is preferably maintained at a positive sulfate ion concentration.  Also preferred is that the second vessel be maintained at a reduced pressure, (e.g. to provide evaporative cooling).  Better filtration rates can thus be obtained due to the favorable shape, size and distribution of the hemihydrate crystals.  Most preferred is that a crystal modifier (e.g. a sulfonic acid, a sulfonic acid salt, tall oil fatty acids or esterified tall oil fatty acids) be present in crystallizer.  Surprisingly, the sulfuric acid used in the process can be less (e.g., 0.5 - 10%) than the stoichiometric amount to convert the calcium in the feed phosphate rock to calcium sulphate.

Abstract: Title of the Invention Fault detecting system for a control system Abstract of the Disclosure In a speed feedback control system wherein a speed command signal and a speed feedback signal are compared and wherein the deviation between these signals is entered into a speed control unit, the speed signal is differentiated to apply a speed damping in order to suppress the oscillations of the control system.  In this case, while the speed command and the actual speed make a great difference transiently, the speed command is approximate to the sum between the speed feedback signal and the damping signal even transiently.          Therefore, the speed command signal is compared with the sum between the speed feedback signal and the damping signal, and fault of the speed control system is detected upon the fact that the deviation has exceeded a predetermined value.
