  • Patent number: 4399058
    Abstract: An aqueous, alkaline impregnating solution for the one-step impregnation of nickel and molybdenum onto a catalyst support is provided by admixing nickel sulfate, preferably an ammoniacal solution of nickel sulfate and an ammoniacal solution of Mo.sup.+VI oxide to form a compatible impregnating solution. Nickel and sulfate ions are present in a ratio of substantially 1 to 1. The use of nickel sulfate in a predissolved ammoniacal solution for admixture with the ammoniacal solution of the Mo.sup.+VI oxide permits a higher metals loading of the impregnating solution and renders the resulting impregnating solution highly suitable for impregnation of nickel and molybdenum onto a catalyst support by the incipient wetness technique in one-step. The catalyst produced using the present impregnating solution is highly active for desulfurization of naphthas, middle distillate oils and asphalt-containing oils.

  • Patent number: 4398005
    Abstract: There is provided a solid, particulate, catalytic complex suitable for the stereospecific polymerization of olefins prepared by reducing TiCl.sub.4, contacting the resultant reduced solid with a complexing agent to obtain a treated solid and contacting the treated solid with TiCl.sub.4 in the presence of silica which has been treated with an aromatic ester. When such a catalyst complex is combined with a suitable activator to polymerize olefins, a high degree of stereospecificity is attained, the activity of the catalyst complex is reduced for polymerization control and the efficiency of the titanium employed is enhanced.

  • Patent number: 4389149
    Abstract: Apparatus for unloading a top unloading mine car that is mounted to pivot about a horizontal axis extending along one side of the base of the mine car includes a hoist chain detachably connected to the mine car at the side opposite the pivotal axis. The hoist chain extends upwardly over a pulley mounted on a positioning crank arm. The pulley moves on rotation of the crank arm from a position substantially vertically above the connection means when the mine car is in an upright position to a position above the pivotal axis. The hoist chain continues around a pulley mounted on a drive crank arm and then to an attachment of restricted mobility. The drive crank arm and the positioning crank arm are rotated in a single direction by drive means which are adapted to rotate the drive crank arm at twice the angular velocity of the positioning crank arm.

  • Patent number: 4385840
    Abstract: Apparatus is provided for blending batches of particulate material that are compositionally heterogeneous into batches of material that are compositionally uniform. The apparatus consists of two vertically aligned cylindrical mixers, including means to transfer product from the first mixer to the second mixer. Each mixer contains six or more vertically aligned partition walls that extend radially from the midpoint of the mixer to the wall to divide the mixer into at least six storage compartments of substantially equal volumetric capacity. The vertical partition walls differ in height in a regular descending order so that as material is charged to and fills one compartment, it overflows the shorter wall to fill the adjacent compartment.

  • Patent number: 4382137
    Abstract: Novel resin products produced by reacting unique polycyclic, aromatic, polycarboxylic acid products with low molecular weight polyols display satisfactory toughness properties and good Barcol hardness values. The process for preparing these novel resin products first involves preparing an intimate, finely divided mixture comprising the acid product derived from the nitric acid oxidation of naturally occurring solid carbonaceous material, a roughly equivalent amount of a liquid polyol, and a suitable acid catalyst. The mixture is then subjected to a precure step which involves heating at temperatures between 80.degree. and 150.degree. C. for from about fifteen minutes to about four hours. The precured mixture may thereafter be subjected to suitable molding conditions at a temperature below about 220.degree. C.
