Abstract: PREPARATION OF 2-(METHYLTHIOMETHYL)-6-(TRIFLUOROMETHYL) ANILINE FROM ORTHO-AMINOBENZOTRIFLUORIDE ABSTRACT This invention relates to a process for the preparation of 2-(methylthiomethyl)-6-(trifluoromethyl) aniline, [MTA], from ortho-aminobenzotrifluoride, (OABT), employing a single solvent transformation via a sulfilimine intermediate. A sulfilimine hydrochloride salt is pre-pared by the oxidative addition of dimethyl sulfide to OABT in the presence of N-chlorosuccinimide. Neutralization of the sulfilimine hydrochloride salt with aqueous sodium hydroxide followed by phase separation results in an organic phase containing free sulfilimine and an aqueous phase generally containing succinimide and/or sodium succinimide. In a preferred embodiment the phase separation is per-formed in such a manner to leave a catalytic amount of succinimide in the organic phase. The free sulfilimine catalytically rearranges at moderate temperatures in the presence of this succinimide catalyst to form MTA. The aqueous phase separated after neutralization of the sulfilimine hydrochloride salt contains succinimide and/or sodium succinimide which may be converted by the action of chlorine to N-chlorosuccinimide which in turn may be recycled to the first step in the process.

Abstract: ABSTRACT OF THE DISCLOSURE    An internal combustion engine combines the efficiency of a radial engine with the practicality of a piston and crankshaft arrangement.  A stationary frame supports a stationary sun gear, and a rotor is pivoted about the axis of the sun gear.  The rotor carries three crankshafts at 120° intervals, each having an eccentric portion.  For each crankshaft there is a cylinder in the rotor, a piston mounted for reciprocation in each cylinder, and a connecting rod from the piston to the eccentric portion of the corresponding crankshaft.  Each crankshaft is fixed to rotate with a respective planetary gear, and all the planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear, so that any point on the pitch circle of a planetary gear describes a cardioid as the planetary gear rotates around the sun gear once.  The crankshaft eccentricity is substantially 1/3 times the pitch radius of a planetary gear.  The eccentric portion of each crankshaft has roller means rotatable about the same axis as the connection between the connecting rod and the eccentric portion, and a ring member with an internal surface surrounds and contacts all of the roller means simultaneously, the ring member being-free to rotate about its own axis.  Fuel metering means provide a combustible mixture for the cylinders, and ignition means are provided to ignite the combustible mixture in each cylinder.  Three valves admit the combustible mixture to each cylinder, each valve having a valve shaft and a valve head at one end of the shaft.  The shaft reciprocates in a bore of the rotor, the bore being substantially radially arranged with respect to the rotor axis.  The shaft has at its end remote from the valve head a roller adapted to contact the internal surface of the ring member over a fraction of each rotor revolution, thereby to depress the valve for the admission of the combustible mixture.  Porting means are provided for exhausting products of combustion from each cylinder.

Abstract: SALT RECOVERY FROM ALUMINUM BLACK DROSS     Abstract Sodium and potassium chloride consolidated granular salt crystals are formed on a bed of granular salt by spraying, for example,  the clarified brine of aluminum black dross upon the heated bed.  The bed cascades in a revolving drum and is maintained at a temperature of about 250°-350°F (121°-177°C). That is, the bed is maintained at a temperature high enough to evaporate the water from the brine before the brine penetrates the bed and low enough to eliminate entrainment of salt in the evaporated water.  An apparatus and process for the recovery of this salt product are claimed.

Abstract: ABSTRACT: Multilayer ceramic capacitor.     A multilayer ceramic capacitor characterized by a stack of alternate dielectric layers of oxidic ceramic material and electrode layers consisting of a mixture of a metal having a high electric conductivity and ceramic particles of a material having a sintering temperature which is above the sintering temperature of the oxidic ceramic material of the dielectric layers. As a result of this electrode composition  the capacitor can be manufactured by means of a uniaxial pressure sintering process in which the stack is sintered while simultaneously applying pressure in the direction transverse to the plane of the layers. This leads to die-lectric layers which are substantially free from pores and have a thickness of at most 20µm.

Abstract: CORRELATION DETECTORS FOR USE IN DIRECT           SEQUENCE SPREAD SPECTRUM SIGNAL RECEIVER                     Abstract A plurality of transmitters synchronized to a common clock each transmit a data signal spread by a common bipolar pseudo-random code having a different assigned code sequence shift.  A receiver, synchronized to the clock, discriminates the signal transmitted by a predetermined transmitter from signals transmitted by the others by generating a first bipolar pseudo-random code that is a replica of the common bipolar pseudo-random code and has a code sequence shift corresponding to that of the predetermined transmitter, and a second bipolar pseudo-random code that is a replica of the common bipolar pseudo-random code and has an unassigned code sequence shift.  The difference between the first and second bipolar pseudo-random code sequences which is a trinary code sequence, is cross-correlated with the incoming signals.  The cross-correlation despreads only the signal spread by the sequence having the predetermined code sequence shift.  Each receiver includes a number of correlation detectors offset from each other by a fraction of a code chip together with decision circuitry to identify cross-correlation peaks for optimum synchronization.  Analog and digital implementations of the correlation detectors are disclosed.
