Abstract: 2,3-Difluoro-5-(trifluoromethyl)pyridine is prepared by contacting a 2,3-dihalo-5-(trifluoromethyl) pyridine with an effective amount of KF or CsF in a polar aprotic solvent (diluent) at an elevated temperature under substantially anhydrous conditions with removal of the difluoropyridine products essentially as they are formed. The starting material may optionally be added as the reaction proceeds to minimize decomposition. The reaction is also optionally conducted in the presence of an acid scavenger and/or a crown ether or other phase-transfer catalyst.

Abstract: Symmetrical tetrachloropyridine is prepared by contacting chlorinated .beta.-(trichloromethyl)pyridines with chlorine in a liquid phase reaction in the presence of from 0.1 to 1.0 mole % of a catalyst.

Abstract: This invention provides an artificial doll eye with a realistic pupil opening allowing light to travel into the eye thrugh the lens some distance into a solid, transparent light shaft in the center of the lens and pupil giving the impression of a real human eye. An iris is simulated by a combination of a thin wafer having a colored surface, and an optical magnifying effect created by the texturing of the plastic in front of the colored wafer.

Abstract: Novel aniline compounds that are useful in preparing N-aroyl N'-phenyl ureas having alkyl substituents in the 2-, 3-, 5- and 6-positions and haloalkoxy in the 4-position of the N'-phenyl which are more active and have a broader spectrum of effectiveness than the known benzoylurea insecticides.

Abstract: This invention provides a pipe saddle assembly comprising (a) an insert housing having an outer open end and an inner open end, the inner open end being adapted for positioning adjacent to and around an opening in the wall of a pipe; (b) an insert having an outer end, an opposite inner end and an opening extending through the insert from its inner end to its outer end, the insert being positioned in the housing such that the inner ends and outer ends of the insert and the housing are respectively adjacent each other; (c) the inner end of the insert being adapted for positioning adjacent to and around the opening in the wall of the pipe; (d) the outer end of the insert being adapted to operatively engage a take-off means; and (e) the insert housing having means adapted to receive and engage the take-off means such that the take-off means holds the insert in a sealing position around the opening in the pipe and against the take-off means.
