Abstract: A drill bit for abrasive jet drilling of wells having a plurality of nozzles extending through the bottom of the bit in position to discharge high velocity jet streams that erode a plurality of concentric grooves in the bottom of the borehole. Each of a plurality of generally sectorially shaped face plates of abrasive resistant material has a wedge extending over the full width of the face plate positioned to ride on the ridge on each side of a groove cut by the stream discharged from a nozzle in a different face plate.

Abstract: ARYL HALIDES, SUCH AS CHOROXYLENE, ARE HYDROLYZED TO THE CORRESPONDING RING HYDROXYLATED ARYL COMPOUNDS, SUCH AS XYLENOL, BY CONTACTING THE ARYL HALIDES AND STREAM WITH A RARE EARTH METAL PHOSPHATE CATALYST, SUCH AS LANTHANUM PHOSPHATE, CERIUM PHOSPHATE AND NEODYMIUM PHOSPHATE. A METHOD OF PREPARING THE RARE EARTH METAL PHOSPHATE IS ALSO DISCLOSED. THE ADDITION OF SMALL AMOUNTS OF COPPER GREATLY IMPROVES THE ACTIVITY OF THE RARE EARTH METAL PHOSPHATE OR YTTRIUM PHOSPHATE FOR THE HYDROLYSIS REACTION.

Abstract: UNWANTED VEGETATION IS COMBATED BY APPLICATION OF A CLASS OF PHENYLOXADIAZOLES WHICH POSSESS EITHER OR BOTH PRE- AND POST-EMERGENT PHYTOXICITY. THE HERBICIDES AS A CLASS ARE SEVERELY TOXIC TO A MINORITY OF PLANT SPECIES, MOST OF THE COMPOUNDS HAVING PRE-EMERGENT EFFECTIVENESS AGAINST CRABGRASS. SOME OF THE COMPOUNDS, AS FOR EXAMPLE, 2-(3'',4''-DICHLOROPHENYL)-5-METHYL-1,3,4-OXADIAZOLE, ARE PARTICULARLY USEFUL FOR PRE-EMERGENT CONTROL OF WEEDS IN A STANDING CROP BECAUSE OF AN ALMOST TOTAL ABSENCE OF POST-EMERGENT PHYTOXICITY. A SMALL GROUP OF COMPOUNDS, SUCH AS 2-DIMETHYLAMINO-5-(2'',4''-DIMETHYLPHENYL)1,3,4-OXADIAZOLE ARE PREDOMINANTLY POSTEMERGENT HERBICIDES AND A NUMBER OF COMPOUNDS, AS FOR INSTANCE, 2-DIETHYLAMINO-5-P-TOLYL-1,3,4-OXADIAZOLE, HAVE BOTH PRE- AND POST-EMERGENT ACTIVITY AND ARE USEFUL IN COMBATING BOTH CRABGRASS AND BROADLEAF WEEDS IN FIELDS OF SMALL GRAINS AND IN BROME GRASS PASTURES.

Abstract: In fluid catalytic riser cracking of a gas oil with a zeolite catalyst the inclusion of controlled amounts of residual oil in the feed results in an improvement in octane value and/or improvement in the distribution of octane value of the gasoline product. The octane number improvement is further enhanced by hydrodesulfurizing the residual oil prior to charging to the FCC unit. However, residual oil is relatively difficult to vaporize and the extent of its vaporization will depend on the equilibrium flash vaporization temperature at the bottom or inlet of the riser. Therefore, the quantity of residual oil in the feed must be controlled in relation to the equilibrium temperature in order to, on the one hand, vaporize and crack a sufficient quantity of residual oil to obtain the octane improvement effect, while, on the other hand, keeping the quantity of residual oil which remains unvaporized below a specified level.
