Abstract: -?-                       PATENT                Abstract A compact, nonvolatile, zero static power, electrically alterable, bistable CMOS latch device is fabricated with single layer of polysilicon.  The single polysilicon layer forms the floating gates of the nonvolatile elements of the device.  The control gates are formed in the substrate by buried N+ diffusions and are separated from their respective floating gates by a thin oxide dielectric.  The circuit can be designed to power-up in a preferred mode even before any programming operation has been performed on it.  Thereafter, the circuit is available to be programmed to either of its two stable states.  After the programming operation is completed and the circuit is latched to one of its two stable states, the fields across the thin oxide dielectrics are minimal and virtually no read disturb condition exist.  Thus, the latch also offers excellent data retention characteristics.

Abstract: DISTRIBUTED PLANAR ARRAY BEAM STEERING CONTROL WITH AIRCRAFT ROLL COMPENSATION                    ABSTRACT        A distributed parallel processing architecture for electronically steerable multi-element RF array antennas provides real time rapid array updates with decreased hardware cost and complexity.  The array is subdivided into plural sub-arrays (each sub-array has more than one RF radiating element) and a phase shift interface electronics ("PIE") device is provided for each sub-array.  Parameters specific to the RF elements within the sub-arrays are preloaded into the corresponding PIE.  Pointing angle and rotational orientation parameters are broadcasted to the PIEs, which then calculate, in parallel and in a distributed processing mannor, the phase shifts associated with the various elements in their corresponding sub-arrays.  Linearization, phase compensation for various factors (e.g., operating frequency, measured characteristics of individual RF elements, feed line delay to individual elements, etc.), and the initial phase shift calculations themselves are thus performed on essentially an element-by element basis without requiring individual calculation hardware for each element.  Array spoiling in response to real time array rotational orientation is provided.  Update rates of greater than 10kHz are attainable.

Abstract: This invention relates to a process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter. Previously-known processes for the preparation of granules of this type have utilized polyamines; this has led to odor and color problems. These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used, the pKa value of the conjugate acid of the anion is greater than 2. The resulting granules are useful at matting and opacifying agents in, for example, paint compositions.

Abstract: Processes of reducing the inorganic sulfur-containing acid and the low equivalent weight organic sulfonic acid content of an acid mass comprising organic sulfonic components and inorganic sulfonating agent contaminants are described. In general, the process comprises the steps of (a) treating the acid mass with ammonia in the presence of water to neutralize the acids in said acid mass and to form a mixture containing the ammonium salts of said acids, (b) allowing separation of the mixture to provide a lower aqueous phase containing water-soluble ammonium salts and an upper phase comprising the oleophilic alcohol and ammonium salts of the organic sulfonic acids, and (c) recovering at least a portion of said upper phase. The efficiency of the reduction of undesirable materials from the acid mass can be increased by subjecting the recovered upper phase to additional water extractions in the presence of the oleophilic alcohol. The ammonium salts of the organic sulfonic acids recovered by the above process can be converted to oil-soluble metal salts by reacting said ammonium salts with a basically reacting metal compound in such amounts and under such conditions as to form metal salts of said organic sulfonic acids. The metals salts prepared in this manner may be neutral metal salts or highly basic metal salts. The neutral and metal basic salts are useful in a variety of applications including lubricants and fuels.
