Abstract: PIGMENTS STABLE AT HIGH TEMPERATURES                   Abstract of the Invention A pigment capable of withstanding elevated tempera-tures such as 175°C is provided by the formation of a spinel of iron and other metal, such as Cu, Ca, Cd, Co, Ba, Sr, Mg, Mn, and Li.  The pigment is made by a method which does not involve a step of calcining at high temperature, such as 600°C to 1100°C, but rather involves precipitation from aqueous solution and subsequent exposure to elemental oxygen, as by aeration, to form submicron-sized particles of desired spinel.          Colors other than yellow may be obtained, and the spinels of Fe-Ba and Fe-Sr have magnetic properties.

Abstract: CHLORINATION OF POLY(VINYL CHLORIDE) IN LIQUID    CHLORINE, AND CHLORINATED POLY(VINYL CHLORIDE) COMPOSITION     ABSTRACT OF THE DISCLOSURE          A process is disclosed for photochlorinating poly(vinyl chloride), ("PVC"), suspended in liquid chlorine ("Cl2") which swells the PVC and permits chlorination to occur in a gel phase. PVC starting material is in the form of solid free-flowing macrogranules which are slurried in from about 5 to about 50 times their weight of liquid C12 in a reaction zone maintained at a temperature in the range from about -50°C to about 50°C, and a pressure sufficient to maintain the chlorine in its liquid state. Since liquid Cl2 itself swells the PVC to provide a gel phase in which photochlorination occurs, no conventional chlorinated hydrocarbon swelling agents, catalytic materials and the like are necessary. The process may be operated as a batch process, or a continuous process. Typical chlorine content of PVC is about 56.7 percent by weight (% by wt), and the product of chlorination is chlorinated poly(vinyl chloride), ("CPVC"). When formed, this CPVC is dissolved in the liquid Cl2 to form a thick syrup-like solution. CPVC is recovered as a solid by evaporation of the liquid Cl2, or as a finely divided solid by adding a halogenated lower alkane slowly to the CPVC syrup. The solid CPVC is homogeneously chlorinated, and its morphology and spectra, especially its 13C nmr spectra, differentiate it from prior art compositions.

Abstract: ENGINE OPERATION RELATED EVENT TIMING SYSTEM          Abstract of the Invention A system for indicating the timing of an engine control event relative to the top dead center position of an internal combustion engine.  A sensor responsive to piston movement develops pulses of equal angular width before and after the top dead center position of a selected piston, and the time relation of the sensor pulses with respect to the initiation of an engine control event is used to determine the timing of the engine control event with respect to the piston top dead center position.  The timing so determined is compensated for engine accelera-tion by taking into account the difference in duration of the two sensor pulses.
