Abstract: A B S T R A C T  O F  T H E  D I S C L O S U R E   Pellets having uniform size and excellent strength properties are manufactured without fluctuations in production from finely-divided moist material by rolling nuclei of substantially mutually identical size in at least one pellet-rolling circuit in the pre-sence of the finely-divided moist material, to form pellets having at least one layer of said material surrounding respective nuclei. A pre-determined quantity of the pellets formed during a rolling operation and comprising pellets which, during said roll-ing operation have obtained the largest diameter, is continuously removed as product pellets from said pellet-rolling circuit, while the remaining pellets formed during the rolling operation are re-turned to the circuit for renewed rolling therein, the supply of finely divided moist material and of the nuclei to the pellet-rolling circuit being adjusted so that the diameter of the product pellets and the amount of material in the pellet-rolling circuit are maintained substantially constant.

Abstract: ABSTRACT     A field effect transistor and method of making the same wherein a semi-conductor layer is placed on an insulating substrate, and wherein the gate region is separated from source and drain regions of a like conductivity type to that of the source and drain regions but of reduced conductivity, the gate electrode and gate region of the layer being of generally reduced length, and the gate region being of greatest length on its surface closest to the gate electrode.  This is accomplished by initially creating a relatively large gate region of one polarity, and then reversing the polarity of a central portion of this gate region by ion bombardment, thus achieving a narrower final gate region of the stated configuration.

Abstract: METHOD OF CORRECTING DOPPLER NAVIGATOR      Abstract of the Disclosure An improved method of processing the data from an airborne monopulse Doppler navigational radar, thereby to determine the aircraft velocity, is disclosed.  In such method, the difference channel return data from each of three sequentially formed radar beams are rotated through an angle to insure that the monopulse difference pattern null associated with each of the three beams re-mains parallel to a selected isodop.  Following rotation, the data are normalized by the sum channel data to reduce the effect of scintillation errors.  After normalization the data undergoes a processing technique to determine the Doppler frequency associated with the monopulse null for each of the three beams.  The Doppler frequency data are subsequently converted to velocity data and combined with velocity data obtained from an inertial platform in order to reduce the long term drift errors associated with the inertial platform.

This control voltage is supplied to all of the voltage controlled amplifiers so as to determine the respective gains thereof.  The signal expansion circuit includes a plurality of voltage controlled amplifiers, an input signal to be expanded being supplied in common to two of such amplifiers.
